Pilonidal sinus: long term results of excision and closure technic. Review of the literature

The Authors report their experience in the surgical management of pilonidal sinus with modified Leichtling technique. Long term results of various treatments proposed in the past are analyzed: it is not possible to identify a satisfactory procedure for the treatment of pilonidal sinus. Ideal treatment should avoid hospital admission and general anaesthesia, assure a short time of healing, a reduced number of complications, a low risk of recurrence and a minimal time off from work. Authors' variations to the original technique show good results for non recurrent pilonidal sinus and a lower number of failed primary healing. Recurrences are probably related to the patient anatomical status which may be modified only by flattening natal cleft or surgically changing follicles orientation of presacral skin, together with a meticulous hygiene and shaving of the presacral healing area as well as a dietary regimen for obese patients.     

Comparison of the functional results of ileorectostomy and ileal pouch-anal anastomosis following total colectomy

To evaluate the functional results of continence reconstruction techniques following total colectomy, an analysis of long-term follow-up, quality of life parameters, and recurrence of basal disease was conducted on 17 patients who underwent ileal pouch-anal anastomosis, and 16 who underwent ileorectostomy. Satisfactory results were achieved in 29 of the 33 patients, partial results were achieved in 3, and only 1 remained totally incontinent. While this outcome was independent of the reconstruction technique, a lower mean daily frequency of defecation, better day-night distribution, faster definitive recovery from surgery, a higher degree of rehabilitation, and a lower frequency of unplanned outpatient visits, hospitalizations, and minor complications were achieved after ileorectostomy than after pouch-anal anastomosis. Furthermore, better results were observed in patients who had undergone surgery for familial polyposis or complicated diffuse colonic diverticulosis, compared to those who had undergone surgery for inflammatory bowel diseases (IBD). During the postcolectomy stage, tumor recurrence was found in 5 of 7 patients with familial polyposis and histologically confirmed malignancy, compared to only 1 of 6 patients with negative histological results. Extracolonic manifestations developed in two patients with ulcerative colitis, and a small bowel obstruction occurred in one with Crohn's disease. These findings emphasize the importance of carefully selecting patients for each type of continence reconstruction method after total colectomy according to their individual requirements.     

The treatment of basal cell carcinoma patients by dermatologists in Netherland

OBJECTIVE: To determine the policy of dermatologists practising in the Netherlands in the treatment of basal cell carcinoma. DESIGN: Written enquiry. SETTING: Catharina Hospital, Eindhoven, the Netherlands. METHOD: All 293 dermatologists practising in the Netherlands were sent a questionnaire in May 1996 containing 15 questions about diagnosis and treatment of basal cell carcinoma. RESULTS: Eighteen forms dropped off because of termination of the practice or joint completion in group practices. The response was 76% (208/275). The diagnosis was made usually on the basis of histological examination (71% of the respondents; 84% in a tumour recurrence). Excision was the preferred treatment for all subtypes of basal cell carcinoma; second choices were cryosurgery or curettage/electrocoagulation. Roentgen contact therapy has been practically abandoned. New methods such as photodynamic therapy and immunotherapy are being used only sporadically on an experimental basis. Most dermatologists regarded tumour recurrences as a bigger problem than primary tumours. They attempt to reduce the percentage of recurrences by giving advice about risk factors (sunlight). CONCLUSION: Too little use is being made of diagnostic biopsy to enable an optimal choice of therapy of basal cell carcinomas, especially in cases of recurrence tumours.     

Nonparasitic cysts of the liver: results and options of surgical treatment

Nonparasitic cysts of the liver (NPHC) are highly variable in respect to appearance and therapeutic approach. The treatment of these cysts varies according to the nature and appearance of the disease. Based on the variable nature of disease and the various therapeutic options, all of which were attempted in our patients, the most suitable mode of treatment for different forms of NPHC are discussed. Ninety-one patients with NPHC who had been treated surgically from 1977 through 1995 were examined retrospectively. Asymptomatic peripheral cysts measuring up to 10 cm do not require further treatment. Computed tomography (CT)-guided aspiration (n = 9) should be regarded as a palliative measure. Within a short period, CT-guided aspiration led to recurrence of symptoms in seven of our patients. Standard treatment of NPHC is fenestration with widest possible excision of the cystic wall, which can be performed laparoscopically (n = 10) or by the conventional surgical mode (n = 54). One patient was initially operated by the laparoscopic technique but developed bleeding, which necessitated conversion to the open mode. Three patients underwent synchronous laparoscopic cholecystectomy. Recurrence rates were similar: 11% in the laparoscopically treated group and 13% in the group that underwent conventional open surgery. Conventional surgical treatment was always successful in cases of solitary cysts. However, in cases of multiple cysts measuring more than 5 cm, conventional surgery was followed by recurrence of symptoms in 26% of patients (7/27), who then had to undergo a second operation. Partial resection of the liver (n = 9) was successfully performed in cases of polycystic disease (n = 5) with concomitant enlargement of the organ as well as in cases of large solitary cysts of the left lobe of the liver (n = 4). In patients in whom we found that the cysts communicated with the ductal system (n = 3), we performed a cystojejunostomy to drain the bile. The complication rate was low. In addition to frequent postoperative ascites, which necessitated no further intervention, we observed infectious complications in four patients. Twenty patients (22%) expired during a mean follow-up period of 6.2 years. Interestingly, deaths were frequently associated with malignancy (11/20). After fenestration of multiple cysts measuring > 5 cm, the patients are at high risk for recurrence. Hence partial resection of the liver is an excellent therapeutic alternative in selected patients with polycystic disease and massive enlargement of the organ in whom the disease could not be controlled by simple fenestration. The results of this study show that laparoscopic fenestration should replace the conventional surgical technique as the gold standard in cases of NPHC because the laparoscopic technique is less stressful for the patient and is associated with a rate of success similar to that of the conventional technique.     

Critical review of phonosurgical methods in the treatment of sulcus vocalis

INTRODUCTION: Sulcus vocalis is an epithelial invagination along the free edge of the membranous vocal fold. It interferes with the glottic closure and vibration pattern. Sulcus vocalis provokes voice fatigue, hoarseness and breathiness, and it usually appears in association with hyperkinetic phonatory pattern. Hyperkinesis develops secondarily, due to the compensatory effort to overcome the deficiency in glottic closure. The treatment of sulcus vocalis is very difficult. Phonosurgery is used, and is followed by postoperative voice therapy. PHONOSURGICAL OPERATIONS: Various surgical techniques are used in the therapy of sulcus vocalis. Over a 10-year period we have operated on 1550 patients with benign lesion of the vocal folds, of whom only 11 had sulcus vocalis (0.7%). We carried out various surgical techniques. a) Excision of sulcus A longitudinal incision of mucosa is performed along the upper surface of the vocal fold, distant of the free edge. Mucosa is undermined caudally, and sulcus is detached from its base. Sulcus is then removed by surgical scissors. With this technique we could not provide physiological phonation and vibration pattern, in spite of an apparent improvement in the voice. b) "Slicing mucosa" technique This procedure was suggested by Pontes, and it also begins with a longitudinal incision followed by creation of inferiorly based slices of mucosa. c) Excision plus rhyroplasty Excision of sulcus is combined with thyroplasty type I in order to achieve medialization of the vocal fold. It can be used in cases with severe glottal gap in order to improve the results of excision. d) Implants Various materials were used in order to enlarge the mass of the vocal fold. In our patients, the results of this procedure were inferior as related to excision surgery. DISCUSSION: The surgical procedure which is safe and accepted by the majority of surgeons has not yet been at our disposal. The treatment of sulcus vocalis should start with voice therapy, which lasts as long as the patient shows a progress. Only then the surgical procedure can be discussed. We obtained the best results with the combination of excision and voice therapy. However, the surgeon and the patient must be aware that the treatment is demanding and long-lasting.     

Importance of extended lymphadenectomy with lateral node dissection for advanced lower rectal cancer

A total of 448 patients with advanced lower rectal cancer who underwent curative wide lymphadenectomy with autonomic nerve preservation were reviewed with respect to surgical techniques, operative burdens, node status, survival rate, and mode of recurrence. Operative time and blood loss in patients who underwent lateral dissection were much greater than those encountered with conventional resection. According to the direction of lymphatic spread in patients with Dukes C disease, the incidence of upward spread was 94% and lateral spread 27%. The overall incidence of lateral metastasis was 14%. The overall 5-year survival was 70%. According to the Dukes classification, the 5-year survival rates were 92% for Dukes A, 79% for Dukes B, and 55% for Dukes C, whereas it was 43% in patients with lateral node metastasis. An analysis of the survival rate was carried out with regard to the number of node metastases, direction of lymphatic spread, and autonomic nerve preservation. The overall incidence of local recurrence was 9.3% and amounted to 16.0% in patients with Dukes C disease. The case of advanced lower rectal cancer was characterized by positive lymph nodes or circular lesions around the circumference (both diagnosed by endorectal ultrasonography). We recommend extended lymphadenectomy with lateral node dissection, as it preserves the autonomic nerve.     

Recurrence of initial pressure ulcer in persons with spinal cord injuries

Whether treated with surgery or by conservative, nonsurgical measures, pressure ulcers recur in 5% to 91% of spinal cord injured (SCI) patients. Factors other than the surgical technique used or the standard conservative management provided may be responsible. A retrospective study of 176 SCI patients with a history of one or more pressure ulcers was conducted at the Department of Veterans Affairs Medical Center at Castle Point, N.Y. Approximately 35% of patients who received either surgical or nonsurgical treatment had a recurrence. Patients who smoked and patients with diabetes or cardiovascular disease had higher recurrence rates.     

Effects of La3+ on lipid fluidity and structural transitions in human erythrocyte membranes

Laparoscopic pyeloplasty is one of several minimally invasive treatment options for UPJ obstruction. In fact, several endoscopically and fluoroscopically controlled methods of incising the obstructed UPJ are now available that are significantly less invasive and less morbid in comparison with open pyeloplasty. However, the long-term success rates of these incisional techniques are less than the rates reported for open pyeloplasty. Several causes of obstruction may be present in the primarily obstructed UPJ, including kinking or compression related to crossing vessels or intrinsic narrowing at the UPJ. One potential reason for the inferior success rates of incisional methods in comparison with open pyeloplasty is that the former techniques address the intrinsically narrowed UPJ but may not address extrinsic problems such as kinking of the ureter associated with fibrotic bands or compression from crossing vessels. Laparoscopic pyeloplasty addresses all potential causes of obstruction. Any fibrotic bands kinking the ureter are divided, and the ureter is spatulated through the level of the UPJ prior to completion of the anastomosis. If a crossing vessel is encountered, a dismembered pyeloplasty is performed, the ureter and renal pelvis are transposed to the opposite side of the vessels, and the anastomosis is completed. An additional disadvantage of incisional techniques is the significant risk of hemorrhage following incision of the UPJ, with as many as 3% to 11% of patients requiring blood transfusion. Hemorrhage may occur owing to an errant anterior incision, the presence of a crossing vessel, incision into the renal parenchyma adjacent to the UPJ, or as the result of bleeding from the percutaneous access site. In contrast, mean estimated blood loss in the authors' series of 57 laparoscopic pyeloplasties was 139 mL, and none of the patients required blood transfusion. Although it is more morbid in comparison with retrograde or fluoroscopically controlled endopyelotomy, laparoscopic pyeloplasty seems at least comparable to antegrade percutaneous endopyelotomy in terms of the length of hospitalization and patient convalescence. Laparoscopic pyeloplasty, however, offers a higher success rate than with incisional techniques, not only from a radiographic standpoint but from a subjective standpoint as determined by the results of the analogue pain and activity questionnaire. The major disadvantage of laparoscopic pyeloplasty is the need for proficiency in laparoscopic techniques and for a longer operative time. As a result, the literature on laparoscopic pyeloplasty consists primarily of small series. Janetschek and co-workers reported on a series of 17 patients who underwent laparoscopic pyeloplasty, including 14 via a transperitoneal approach and 3 via a retroperitoneal approach. Procedures performed included ureterolysis alone, dismembered pyeloplasty, and nondismembered (Fenger) pyeloplasty. "Fenger-plasty" is similar to Y-V pyeloplasty and is performed by incising the UPJ longitudinally and closing the incision transversely in a Heineke-Mikulicz fashion. Janetschek and colleagues reported a 100% success in the eight patients who underwent dismembered pyeloplasty but believed that this technique was too cumbersome and should be reserved for patients with long stenoses, dorsally crossing vessels, or large renal pelvis. Because two of the four patients undergoing ureterolysis alone failed treatment, Janetschek and colleagues have abandoned this technique. They now prefer the Fenger-plasty technique, even in the setting of ventrally crossing vessels, because the technique can be performed quickly with one to three sutures, and the anastomosis can be sealed with fibrin glue and a flap of Gerota's fascia. Their experience with this technique, however, remains relatively limited. Technologic advances such as the Endostitch device have facilitated reconstructive laparoscopic procedures such as pyeloplasty. (ABSTRACT TRUNCATED)     

Subsegmentectomy or segmentectomy in hepatocellular carcinoma

BACKGROUND/AIMS: We determined the optimal therapeutic strategy for improving survival in patients with hepatocellular carcinoma (HCC), based on an analysis of our surgical results. METHODOLOGY: Between January 1990 and December 1996, 205 patients underwent initial curative hepatectomy. The liver volume to be resected was decided according to the plasma retention of indocyanine green 15 minutes after injection. The appropriate subsegmental and segmental areas were disclosed by staining under ultrasonographic guidance. Limited resection or tumor enucleation was performed in 119 patients, subsegmentectomy or segmentectomy in 71, and lobectomy or extended lobectomy in 15. RESULTS: Intrahepatic recurrence was documented in 115 patients, 46 of whom died from cancer recurrence. Disease free survival was 65% after 1 year, 35.1% after 3 years and 25.3% after 5 years. The type of hepatectomy (limited vs. subsegmental or segmental resection) significantly affected the cumulative survival (p = 0.047) and disease free survival rates (p < 0.01). Among the 115 patients with recurrence, 22 patients underwent repeated hepatectomy combined with TAE (transcatheter arterial embolization) and the remainder underwent TAE alone. Patients who underwent repeated hepatectomy combined with TAE survived significantly longer after recurrence than those who underwent TAE alone (p = 0.0197). CONCLUSION: Initial subsegmentectomy or segmentectomy prolongs disease free survival, and patients eligible for repeated hepatectomy combined with TAE after recurrence have a good chance of long-term survival. Subsegementectomy or segmentectomy should be performed in a lot more HCC patients in order to improve survival.     

Humor in the helping relationship

BACKGROUND: Our aim was to determine the frequency, survival and symptomatic local recurrence rate of patients with a positive proximal resection margin in a series of patients having a resection for carcinoma of the oesophagus or stomach. METHODS: A retrospective study of pathology reports and case notes. Survival and data on local recurrence were obtained from the patient or general practitioner. RESULTS: Ten (11.5%) of 87 patients having a gastric or oesophageal resection for carcinoma had a positive proximal resection margin. All 10 patients underwent a palliative resection for late-stage disease. Nine were dead at an average 8.3 months (range 2-20 months) post-resection and one patient remains alive at 9 months. Only one of these 10 patients had evidence of a local recurrence with recurrent dysphagia prior to death at 11 months. CONCLUSION: A high incidence of a positive proximal resection margin was found. This occurred in patients who underwent a palliative resection for late-stage disease, most of whom died before local recurrence became a problem. For patients recognized as having late-stage disease, surgery for symptom palliation need not be aggressive (such as to include a thoracotomy) because achieving microscopic clearance is unlikely to affect the long-term outcome.     

Wound seeding associated with endometrial cancer

We report a patient with well-differentiated adenocarcinoma of the endometrium who developed a recurrence in the anterior abdominal wall probably secondary to wound seeding at the time of her original surgery. She underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy. She then received 15 mCi of 32P for positive peritoneal washings. She was free of disease until 2 years later when a large lower incision mass developed. She had no evidence for intra-abdominal disease and a radical resection with a myocutaneous flap was undertaken. Radical resection for isolated metastases may be of benefit for patients with endometrial cancer. Patients with positive cytology should be observed closely for incisional recurrence.     

A pulmonary vascularization study in pulmonary atresia with an interventricular defect in relation to the presence of a chromosome 22 deletion

BACKGROUND/AIMS: Bare sclera resection with and without use of mitomycin C and conjunctival autograft placement are three surgical techniques currently in use for the treatment of primary pterygium. The purpose of this study was to determine through a meta-analysis the risk for postoperative pterygium recurrence comparing the three surgical treatment modalities. METHODS: A search through Medline for randomised controlled clinical trials comparing at least two of the three surgical techniques in the treatment of primary pterygium, along with a hand search of all references in relevant papers, was conducted. All eligible clinical trials were graded for quality utilising the Detsky score; those studies with a score of 0.5 or greater were included. The main outcome measurements were the pooled odds ratios and 95% confidence intervals for the risk of pterygium recurrence. These were calculated utilising the Mantel-Haenszel method. RESULTS: Five eligible studies with an adequate quality score were retrieved, three comparing bare sclera resection with and without mitomycin C use, one comparing bare sclera resection with conjunctival autograft placement, and one comparing both. The pooled odds ratio for pterygium recurrence in patients who had only bare sclera resection was 6.1 (95% confidence intervals, 1.8 to 18.8) compared with the patients who had conjunctival autograft placement and 25.4 (9.0 to 66.7) compared with the patients who received mitomycin C. CONCLUSIONS: The odds for pterygium recurrence following surgical treatment of primary pterygium are close to six and 25 times higher if no conjunctival autograft placement is performed or if no intra/postoperative mitomycin C is used, respectively. Surgeons and clinical triallists should not be encouraged in the use of bare sclera resection as a surgical technique for primary pterygium.     

Percutaneous femoropopliteal graft placement

Femoropopliteal bypass surgery is now recommended for the treatment of long-segment or diffuse superficial femoral artery disease. The authors describe a technique for percutaneous placement of a prosthetic femoropopliteal graft. The technique has been accomplished with conventional polytetrafluoroethylene graft material and a variety of implantation techniques. Technical success was achieved in eight patients who underwent graft placement. Grafts up to 28 cm in length were placed, and graft patency was demonstrated up to 6 months after implantation. Six of the eight patients were asymptomatic during the follow-up period; one patient who had symptoms during this time underwent thrombolysis and redilation of the distal stent, and the symptoms resolved. This study demonstrates the feasibility of percutaneous graft placement in the femoral artery, but durability must be established in relation to traditional bypass surgery before it can be recommended on a wider scale.     

Clinical efficacy of ultrasound guided percutaneous drainage of abscesses in patients with leukaemia and lymphoma

Ultrasound guided percutaneous drainage (US-PD), a minimally invasive technique, has been reported as highly effective for the treatment of deeply located abscesses, particularly in immunocompromised patients. Therefore, we retrospectively studied its therapeutic efficacy and safety in a series of 14 patients with leukaemia and lymphoma. We collected the clinical and sonographic data of 14 patients with various types of leukaemia and lymphoma. These patients were consecutively observed in four clinical centres with long-term experience with ultrasound guided therapeutic techniques. The cases were analysed according to underlying disease, clinical features, location of the abscess, drainage technique, microbiological data and both short- and long-term outcome. In our series, 11 patients were treated with repeated ultrasound guided needle aspirations (US-NA) and 3 underwent catheter drainage (US-PCD). In 12/14 cases the procedure was successful (86%): the mortality rate was 14%. 5 patients died during the follow-up period because of the underlying disease, without abscess recurrence. No complications were reported. Our data suggest that ultrasound guided percutaneous drainage should be considered the first choice, minimally invasive procedure for the treatment of deeply located abscesses in patients with leukaemia and lymphoma.     

A surgical algorithm for the treatment of Peyronie's disease

PURPOSE: When conservative treatment of Peyronie's disease fails, the optimal surgical approach is not well defined. Multiple factors, including penile rigidity, degree of curvature, shaft narrowing with hinge effect and erectile response to vasoactive penile injections, indicate that no single approach is likely to solve the problem in all patients. MATERIALS AND METHODS: A surgical algorithm was developed for the treatment of Peyronie's Disease based on our previous surgical experience, which was used prospectively in 103 consecutive men. Penile straightening without prosthesis was offered to patients with adequate rigidity for coitus. Specifically, for mild to moderate curvature less than 60 degrees without hourglass or hinge effect deformity the less complicated tunica albuginea plication procedure was performed. For those men with more severe, complex curvature greater than 60 degrees and/or significant hourglass or hinge effect deformity plaque incision or partial excision with dermal grafting was offered to limit shaft shortening and to reconstruct a shaft with normal caliber to provide optimal axial support during intromission. For men with poor sexually induced erections and/or inadequate response to intracavernosal pharmacotherapy penile prosthesis placement was recommended to provide adequate straightening and rigidity. RESULTS: Of 22 patients who underwent plication procedures 91% remained potent and the penis remained straight postoperatively. Of 52 patients who underwent an incision or partial excision and grafting procedure, 48 had dermal grafts with the penis remaining straight in 94% and 75% remaining potent postoperatively. A total of 29 patients received a prosthesis with the penis remaining straight in 93% who were sexually active postoperatively. During the follow up period (mean 22.3 months) there have been no mechanical device failures. CONCLUSIONS: Surgical outcome was optimized with this algorithm, which correlates surgical complexity to the underlying severity of the penile deformity and erectile capacity.     

Effectiveness of mastectomy by response to induction chemotherapy for control in inflammatory breast carcinoma

BACKGROUND: Controversy exists as to the treatment regimen necessary to best provide optimal local control for inflammatory breast carcinoma (IBC). This study was conducted to determine if mastectomy combined with radiotherapy offered any advantages over radiotherapy alone in patients with IBC who had been treated with doxorubicin-based combination chemotherapy. METHODS: A retrospective review of 178 women treated for IBC on doxorubicin-based multimodality therapy protocols between January 1974 and September 1993 was performed. Clinical and histologic response to treatment, time to local recurrence, survival, and ultimate control of local disease were analyzed. Kaplan-Meier analysis was used to examine survival and relapse times, and Fisher's exact test was used to test differences in treatment outcomes. Significance was determined at p < or = 0.05. RESULTS: Median follow-up was 89 months (range 22 to 223 months). Locoregional disease persisted in seven patients and recurred in 44 patients who had been rendered disease free at a median time of 10 months. The mortality rate after a local recurrence (LR) was 98%, and all patients but one with LR developed systemic metastases. Response to induction chemotherapy influenced the incidence of LR, and the amount of residual disease found on histologic examination of mastectomy specimens was highly prognostic for local failure. Patients who underwent mastectomy in addition to radiotherapy had a lower incidence of LR than did patients who received radiotherapy alone (16.3% vs. 35.7%, p = 0.015). CONCLUSIONS: The addition of mastectomy to combination chemotherapy plus radiotherapy improved local control in patients with IBC. The addition of mastectomy to chemotherapy plus radiotherapy improved distant disease-free and overall survival in patients with a clinical complete or partial response to induction chemotherapy. Patients who had no significant response to induction chemotherapy received no survival or local disease-control benefit from the addition of mastectomy to their treatment regimen. These patients should be considered for entry into clinical trials of new treatment regimens.     

Salivary duct carcinoma: a report of nine cases

We studied loco-regional recurrence during follow-up (median observation time 8 years) in 1,153 patients, who underwent modified mastectomy and were randomly assigned to one of the following postoperative treatments; Premenopausal patients: radiotherapy, cyclophosphamide, or both; Post-menopausal patients: radiotherapy, tamoxifen, or both. Recurrence occurred in a total of 419 patients, 123 of whom had loco-regional recurrence with or without distant metastasis. The loco-regional recurrence rate was 7% in the irradiated subgroups and 17% in the non-irradiated subgroups, the corresponding cure rates being 43% and 58%. Complete remission of all local recurrence was obtained after the first treatment in 67% of the cases, and was persistent in 67% of them (44% overall). Complete remission was obtained in all patients with local recurrence who received local treatment only, and was persistent in 65%. Of local recurrences treated with a combination of surgery, radiotherapy and hormone therapy, complete response was obtained in 94% of the patients, and was persistent in 94% of them (88% overall). Complete remission of all regional recurrence was obtained after the first treatment in 58% of the patients and was persistent in 67% of them (39% overall). Postoperative radiotherapy reduced not only the total number of loco-regional recurrences but also the number of uncontrolled loco-regional recurrences. Aggressive local treatment would appear to yield both satisfactory initial control and, when combined with the hormone therapy, a high rate of persistent loco-regional control.     

In cell amplification

130 total hysteroscopic resections of the endometrium (RE) were performed at the Department of Gynecology and Obstetrics of the Deutschlandsberg Hospital from August 1, 1992 to May 31, 1997. 115 patients (88.5%) suffered from distinctive therapy-resistant uterine bleeding in terms of hypermenorrhea and menorrhagia, frequently combined with poly- and dysmenorrhea. 15 (11.5%) women who had previously been operated for breast cancer developed--during continuous treatment with tamoxifen--endometrial hyperplasia or polyps on which RE was performed after a hysteroscopic biopsy or resection had been carried out in a second setting. The operation showed that 98 out of 115 patients (85.2%) had pathologic anomalous uteri which were the organic cause of the uterine bleeding. Only 17 women (14.8%) suffered from dysfunctional uterine bleeding (12 cases) or from iatrogenically reduced coagulability (5 cases). The majority of the women (106 cases = 81.5%) were older than 40 (average 46.9 +/- 6.21 years). All RE were performed under inhalation anesthesia whereby the complete uterine cavity up to the inner orifice of the uterus was resected with the resectoscope loop. 92 out of 130 patients (70.8%) underwent a hysteroscopy or a dilatation and curettage before the RE. 77 patients (66.9%) received pretreatment with drugs to reduce the endometrium. 15 women (13.0%) underwent a laparoscopic tubal sterilization in the same setting. Finally, the results of 107 patients were analyzed excluding dropouts and patients who had undergone continuous treatment with tamoxifen and those who had an observation time of less than 6 months. After an observation period of 6-58 months, the success rate was 84.1%. For treatment of relapses 7 second resections were performed, whereby in 1 patient with a further uterine bleeding the uterus had to be extirpated. Nine of the 10 remaining patients had a hysterectomy, 1 patient refused any further treatment. The total hysterectomy rate was 12.2%. Basically, RE is absolutely practicable as far as the treatment of abnormal uterine bleeding is concerned, since hysterectomy can be avoided in a number of cases. Satisfactory long-term results, however, can only be achieved if indication and operation technique are of high quality. A problem which has not yet been solved is the indication and treatment of proliferating adenomyosis uteri interna.     

Supratentorial malignant gliomas in childhood: a single institution perspective

BACKGROUND: A retrospective study evaluated the clinical characteristics, prognostic factors, and outcome of patients with newly diagnosed supratentorial malignant gliomas treated with preirradiation chemotherapy. METHODS: Of 41 patients with supratentorial malignant gliomas accrued between 1984-1994, all had neuroimaging documentation of the extent of resection and 37 had complete neuraxis staging prior to treatment; 80% were treated with one of a variety of neoadjuvant chemotherapy regimens. RESULTS: Thirteen patients had anaplastic astrocytoma (AA), 25 had glioblastoma multiforme (GBM), and 3 had anaplastic oligodendroglioma. Gross total resection (GTR) was performed in 10 patients, subtotal resection (STR) in 22 patients, and biopsy (Bx) alone in 9 patients. For the entire group the 3-year overall and progression free survivals were 35 +/- 8% and 18 +/- 6%, respectively. Tumor recurrence was dominantly local. However, 9 patients with initially local disease failed at a distant neuraxis site, giving a 26 +/- 7% actuarial risk of dissemination at 3 years. The only significant prognostic factor was extent of tumor resection: patients who underwent GTR survived longer than those who underwent STR or Bx (P = 0.004). Histology (GBM vs. AA), age, and the use of enhanced local dose radiation therapy (brachytherapy or stereotactic irradiation) did not affect survival. CONCLUSIONS: Neoadjuvant chemotherapy was not associated with a survival rate significantly different from that observed in adjuvant chemotherapy studies. Systematic neuraxis staging at diagnosis and recurrence revealed a rate of neuraxis dissemination as a component of recurrence that was higher than previously reported; the utility of craniospinal irradiation in preventing isolated dissemination remains uncertain.     

Surgical treatment of locally recurrent rectal carcinoma

PURPOSE: This study was performed to analyze the outcomes of patients with local (pelvic) recurrence (following radical surgery for rectal cancer) who subsequently underwent a new operation. METHODS: Forty-five patients (19 percent of 213 local recurrences) were explored surgically because the disease was deemed to be confined to the pelvis with a limited extension and, therefore, amenable to surgical cure. RESULTS: Only 21 of the 45 patients who underwent surgical exploration had an oncologically radical operation (R0). In the remaining 24 patients, either a simple exploration or palliation or a nonradical procedure (R1-R2) was performed. In the R0 group, there was a 19 percent five-year survival rate vs. a 0 percent rate in the R1-R2 group (median survival, 4 months). Site of recurrence (anastomosis vs. other sites) was statistically associated with a higher chance of long-term survival for those who underwent an R0 operation. CONCLUSIONS: The prognosis of locally recurrent rectal cancer is dismal; less than 10 percent of all patients who underwent surgical treatment benefit from reoperation with an overall survival for five years. On the basis of these results, we no longer consider the surgical approach as the primary option for treating locally recurrent rectal cancer.
