Purification and characterization of a cytotoxin from Enterobacter cloacae

OBJECTIVE: To document our evolving surgical management of colonoscopic perforation and examine factors crucial to the improvement of patient care. DESIGN: We conducted a computer-based retrospective analysis of medical records (1980 through 1995). MATERIAL AND METHODS: Among 57,028 colonoscopic procedures performed, 43 patients (0.075%, or 1 perforation in 1,333 procedures) had a colonic perforation. Two additional patients were treated after colonoscopy performed elsewhere. The outcomes analyzed included surgical morbidity and mortality. RESULTS: Twenty-six women and 19 men who ranged in age from 28 to 85 years (median, 69) were treated for colonic perforation. More than 80% of perforations occurred during the latter half of the study period because of the increased volume of colonoscopic procedures (8 perforations among 12,581 examinations from 1980 through 1987 versus 35 perforations among 44,447 colonoscopies from 1988 through 1995). Emergency laparotomy was performed in 42 patients (93%). Perforations occurred throughout the colon: right side = 10; transverse = 9; and left side = 23. Three patients without evidence of peritoneal irritation fared well with nonoperative management. Most patients underwent primary repair or limited resection in conjunction with end-to-end anastomosis. In 14 patients (33%), an ostomy was created. One patient underwent laparotomy without further treatment. Intra-abdominal contamination ranged from none (31%) to local soiling (48%) to diffusely feculent (21%). Postoperative complications occurred in 12 patients and were associated with older age (P = 0.01), large perforations (P = 0.03), and prior hospitalization (P = 0.04). No postoperative deaths occurred. CONCLUSION: Despite a consistently low risk of colonic perforation, the increasing use of colonoscopy in our practice has resulted in an increased number of iatrogenic colonic perforations. In order to minimize morbidity and mortality, prompt operative intervention is the best strategy in most patients. Non-operative management is warranted in carefully selected patients without peritoneal irritation.     

Rifabutin versus placebo in combination with three drugs in the treatment of nontuberculous mycobacterial infection in patients with AIDS

OBJECTIVE: Most endoscopic perforations of the colon occur in the rectosigmoid area and are thought to be secondary to direct injury from the endoscopic instrument. The aim of this study was to describe the mechanisms of injury and clinical outcome of endoscopic perforation involving the cecum. METHODS: Retrospective review of 6684 consecutive colonoscopic procedures performed at a university hospital over a 7-yr period. RESULTS: Colonoscopy was complicated by perforation in 0.22%. Five of the 15 perforations occurred in the cecum. The mean age of these five patients was 79.6 +/- 17.7 yr (mean +/- SD). Indications for the procedure were bleeding (n = 4) and suspected obstructing cecal mass (n = 1). Abnormal endoscopic findings included diverticulosis, vascular malformations, cecal ulcer/inflammation, mass, and polyps. Perforation was directly attributable to an ancillary procedure (three routine biopsies, one electrocautery) in the cecal area in four patients, and cecal pathology (inflammation, ulceration) was a contributing risk factor in three patients. Mortality was 80%. In contrast, a noncecal perforation usually occurred at the sigmoid region and was associated with technical difficulties, e.g., inability to traverse a stricture or reach the cecum. CONCLUSIONS: Routine forceps biopsy (without electrocautery) is an under-recognized cause of cecal perforation. Ancillary endoscopic interventions in the cecal region should be minimized in elderly patients with evidence of cecal inflammation. Pneumatic injury may be an additional risk factor for cecal perforation in patients with a colonic stricture or a tortuous colon.     

Does colonoscopic polypectomy reduce the incidence of colorectal carcinoma?

The study's objective was to examine whether there is evidence that colonoscopic polypectomy reduces the incidence of colorectal cancer. The records of all patients who underwent colonoscopic polypectomy by a single surgeon between 1974 and 1991 were reviewed. Patients with colorectal cancer diagnosed at the initial colonoscopy, with a history of colorectal cancer, inflammatory bowel disease or familial adenomatous polyposis or with only hyperplastic polyps were excluded. There were 1008 remaining patients, of whom 645 have attended at least one follow-up colonoscopic examination, and these 645 patients from the basis of the study, because the incidence of cancer is known exactly in this group. The mean period of follow up was 4.4 years and the mean number of follow-up colonoscopic examinations was 2.2. There was a total of 2847 person-years of colonoscopic follow up. The expected incidence of cancer, age and sex adjusted, is calculated using Australian epidemiological figures. The observed incidence of cancer was 3 cases (all asymptomatic) per 2847 person-years, which is indistinguishable from the general population's risk of 3.75 cases per 2847 person-years. Analysis of previous publications suggests that patients with adenomas are at an increased risk of developing colorectal cancer of about 2.5 times the general population's risk. If correct, then the observed incidence of 3 cases per 2847 person-years is less than the expected incidence of 9.4 cases per 2847 person-years. This analysis suggests colonoscopic polypectomy does reduce the incidence of colorectal cancer.     

Conservative management of colonoscopic perforation can be misleading

The management of colonoscopic perforations is still evolving. Many now agree to the selective management strategy: Perforations during diagnostic colonoscopy being treated surgically and therapeutic ones treated conservatively. However, patients with diagnostic perforation, if they have clean bowel and no signs of peritonitis, are still treated conservatively. We report here the case of a woman who had a perforation during diagnostic colonoscopy who was treated medically with good progress and no signs of peritonitis during her hospital stay for five days, but collapsed and died at home two days later.     

Complications in the endoscopic polypectomy of colonic adenomas

Endoscopic polypectomy is associated with a small but definite risk of bleeding and perforation. Patients with large adenomas are thus usually hospitalized for endoscopic resection. In order to evaluate whether these procedures can be performed in the setting of one day surgery, we retrospectively analyzed the complications and results of polypectomy done in the period from 1.1.1990 through 31.12.1994. Of 1399 colorectal adenomas respected in 680 patients, 385 (28%) were larger than 1 cm. Altogether we observed only 3 (0.2%) clinically significant complications: bleeding was seen in 2 patients, of whom only one required transfusion of one unit. One patient required surgery because of perforation after removal of a sessile cecal adenoma with uneventful outcome. These results show that endoscopic resection of colorectal adenomas is safe even if the polyps are large.     

Failure of colonoscopic surveillance in ulcerative colitis

A prospective surveillance programme for patients with longstanding (> = 8 years), extensive (> = splenic flexure) ulcerative colitis was undertaken between 1978 and 1990. It comprised annual colonoscopy with pancolonic biopsy. One hundred and sixty patients were entered into the programme and had 739 colonoscopies (4.6 colonoscopies per patient; 709 patient years follow up). Eight eight per cent of examinations reached the right colon. There was no procedure related death. One Dukes's A cancer was detected. Forty one patients (25%) defaulted. Of these 25 remain well; 13 are unaccounted for, and one died from colonic cancer. One patient had colectomy for medical reasons, and another died of carcinoma of the pancreas. Retrospectively an additional 16 eligible patients were identified who had not been recruited. Of these, 14 remain well, two are unaccounted for. None developed colonic cancer. Four patients refused colonoscopy. All remain well. Over the same period seven other cases of colonic cancer were found in association with ulcerative colitis, two in patients who had erroneously been diagnosed as having only proctitis and were therefore not entered into the programme, but were found at operation to have total colitis, one in a patient with colitis of seven years duration, and four patients who had previously attended the clinic but had been lost to follow up before 1978 and then had represented with new symptoms during the surveillance period. Thus, of the nine colitis related cancers diagnosed in this centre during the study period only one was detected by the surveillance programme. The results of this large study, a a review of published works, cast doubts on the effectiveness of colonoscopic surveillance programmes in detecting colorectal cancer in patients with ulcerative colitis.     

Outcome of large-bowel perforation in patients with colorectal cancer

PURPOSE: Perforation of the colon is seldom associated with malignant disease. Operative mortality varies widely in published studies and little is known about patterns of failure and long-term outcome. An observational study was undertaken to assess the outcome of colorectal cancer complicated by perforation. METHOD: We reviewed a series of 83 consecutive patients treated during a 14-year period at one institution. RESULTS: Fifty-four (65 percent) patients had perforation of the tumor itself, and 29 (35 percent) had diastatic perforation proximal to an obstructing tumor. Twenty-six (31.5 percent) patients had metastatic disease at laparotomy. Primary resection of the diseased segment was performed in 47 (87 percent) patients with perforation of the tumor itself and in 21 (72.4 percent) patients with diastatic perforation proximal to an obstructing tumor. However, only 57 patients (39 (72.2 percent) with perforation of the tumor itself; 18 (62 percent) with diastatic perforation proximal to an obstructing tumor; P = not significant) were potentially cured. Operative mortality was 16.7 and 48.3 percent, respectively (P < 0.01) and correlated significantly with Hinchey's stage (P < 0.001) and advanced disease (P = 0.023). At a mean follow-up of 43 (median 31) months, 21 (46 percent) of the 46 potentially cured survivors were alive. The local recurrence rate was 22.9 percent in patients with perforation of the tumor itself and 18.2 percent in patients with diastatic perforation proximal to an obstructing tumor (P = not significant). Peritoneal seeding occurred in 17 and 0 percent (P = not significant); the mean disease-free interval was 33.9 and 49.9 months (P = not significant); and five-year cumulative disease-related survival probability was 0.51 and 0.90 (P = 0.049), respectively. CONCLUSIONS: Diastatic perforation proximal to an obstructing tumor is associated with higher operative mortality and better cancer-related survival than a tumor perforating through the bowel wall. Early diagnosis in diastatic perforation and aggressive management of sepsis associated with radical surgical resection is recommended.     

In vitro antimalarial activity of a new organometallic analog, ferrocene-chloroquine

OBJECTIVES: Diagnostic peritoneal lavage (DPL) had been widely used in evaluating patients with suspected intraperitoneal injuries due to its high sensitivity. If the positive criteria are strictly followed, however, the incidence of nontherapeutic laparotomies will be unacceptably high. This realization has become more important recently with the popularization of nonoperative treatment for blunt solid organ injuries. For these patients, the early diagnosis of an associated hollow organ perforation is mandatory. METHODS: Three hundred and twenty patients undergoing DPL over an 18-month period were retrospectively reviewed to evaluate the usefulness of "cell count ratio" in diagnosing hollow organ perforation. The cell count ratio was defined as the ratio between white blood cell count and red blood cell count in the lavage fluid divided by the ratio of the same parameters in the peripheral blood. RESULTS: Two hundred twelve patients were diagnosed as having a positive DPL according to the classic criteria. Forty-four patients (21%) had a cell count ratio of greater than or equal to 1. The diagnosis at laparotomy was small bowel perforation in 31 patients, colon perforation in eight patients, diaphragmatic hernia in one patient, pancreatic transection in two patients, and liver laceration in two patients. None of the patients with a cell count ratio of less than I sustained hollow organ perforation. The average interval from injury to DPL was 5 hours, with the shortest being 1.5 hours. CONCLUSION: A cell count ratio of greater than or equal to 1 predicted hollow organ perforation with a specificity of 97% and a sensitivity of 100%. The selective use of the cell count ratio has improved the probability of early diagnosis of bowel perforation without increasing the cost of care. Nonoperative management can be applied more confidently to those patients sustaining a blunt solid viscus injury of the abdomen if the cell count ratio is low. We conclude that the cell count ratio of DPL effluent is a very sensitive and specific indicator of hollow organ perforation. In the treatment of blunt abdominal injuries, if the cell count ratio is positive, nonoperative treatment should be abandoned and a laparotomy undertaken.     

CYP2D6 genotype and smoking behaviour in cigarette smokers

BACKGROUND: Esophageal perforation is one of the most dreaded complications in therapeutic gastrointestinal endoscopy. We assessed the frequency of esophageal perforation after endoscopic procedures in a highly specialized endoscopy unit and compared clinical outcomes in patients undergoing either surgical or conservative management. METHODS: From January 1985 to June 1996, 1011 instrumental endoscopic procedures (dilatation and bougienage) were performed in our department. The computerized complication database was searched to identify all patients with esophageal perforation during this same period, and their records were reviewed. RESULTS: Seventeen esophageal perforations (1.7%) occurred in the course of 1011 procedures. Four perforations resulted from balloon dilatation, and 13 were secondary to bougienage. Six patients were managed surgically (35%), all of them recovering uneventfully. Eleven patients were managed conservatively, mainly because they were unfit for surgery. Survival rate in this group was 82%; only two patients died, both of whom had underlying malignant disease. CONCLUSIONS: The current concept in management of esophageal perforations comprises surgical as well as medical treatment. In well-selected cases, non-operative treatment can be considered with favorable results.     

Progressive osseous heteroplasia. Report of a family

OBJECTIVES: The purposes of this study were to investigate the use of computed tomography (CT) imaging in patients with suspected acute appendicitis and to evaluate the impact of CT on negative appendectomy and perforation rates. In patients clinically diagnosed of acute appendicitis the reported overall negative appendectomy rate is about 15-20%; 10% in men and 25-45% in women of childbearing age. This is associated with a perforation rate of 21-23%. METHODS: This is a retrospective analysis of 146 consecutive patients presenting with clinical symptoms suspicious of appendicitis over a 2-yr period in whom CT examinations were performed before therapy was instituted. The overall negative appendectomy and perforation rates were calculated for the entire group, as well as for the 54 women aged 15-50 yr in the childbearing cohort. RESULTS: The negative appendectomy rate was 4% in 122 patients operated on and the perforation rate was 22%. Among 36 women 15-50 yr of age operated on, the negative appendectomy rate was 8.3% and the perforation rate was 19%. Surgery was avoided in 24 patients, 18 of whom were women of childbearing age. CONCLUSIONS: The judicious use of CT imaging in patients with equivocal clinical presentation suspected of having appendicitis led to a significant improvement in the preoperative diagnosis. It resulted in a substantial decrease in the negative appendectomy rate compared to previously published reports, without incurring an increase in the perforation rate.     

Management of colorectal foreign bodies

Colorectal foreign bodies (CFBs) present a serious dilemma regarding extraction and management. In an 11-year period ending March 1994, 48 patients presented to the University of California, San Diego Medical Center and Hammersmith Hospital London with CFBs. Identified patients charts were reviewed in a retrospective manner and the medical literature was reviewed. A wide variety of CFBs were identified and all were extracted transanally. Circumstances surrounding CFB insertion was most commonly sexual stimulation (78%), but included sexual assault (10%). Extraction in the emergency department was successful in 31 (63%) patients. Operating room extraction was performed in 18 (37%) patients; in 12 cases the CFBs were simply extracted under anaesthesia, five patients required primary repair and diverting colostomy for rectal perforation and one required primary repair of an external anal sphincter laceration. Post-extraction observation following simple extraction ranged from immediate discharge to 72 h (mean 13.1 h) and there were no reported complications. A thorough history is essential in order to identify those cases that have resulted from assaults. With adequate sedation, most CFBs can be extracted transanally either in the emergency department or operative suite under direct vision. Sigmoidoscopy is required following extraction to evaluate mucosal injury or perforation. After effortless extraction of a smooth object, with no evidence of mucosal injury, the patient can be discharged after a short period of observation. Rectal perforation can be treated with primary repair and diverting colostomy with low morbidity. This is a relatively common surgical dilemma that requires a thorough history, physical examination, radiographs inventiveness to treat. Additionally, the physician should demonstrate a caring attitude and not subject the patient who is suffering pain and embarrassment to ridicule.     

Hartmann's procedure in colorectal tumors. Evolutions of the indications in a series of 46 patients

The Authors report a retrospective study of 46 cases of Hartmann's operation in order to analyze the changing indications to this procedure in the management of colo-rectal cancer. The Hartmann's is operation has been performed in 46 out of 723 patients (6.4%) with colorectal cancer treated surgically from 1973 to 1997. Data concerning the indications have been analyzed in two consecutive periods, from 1973 to 1985 and from 1986 to 1997, respectively. In the first period, the procedure has been performed in patients with neoplastic perforation (40% of Hartmann's cases), and in an elective basis in patients with locally invasive tumor or intra-abdominal metastasis (20%). Indications for the procedure in the period 1986-1997 have been locally invasive tumor and/or distant metastasis (52.8% of Hartmann's procedures), neoplastic perforation (22.2%), high surgical anaesthesiologic risk (22.2%) or intestinal obstruction (2.8%). In the second period it has been noted a decrease of the number of patients that underwent Hartmann's procedure for bowel obstruction, and an increase in the number of cases in which the operation was performed for neoplastic perforation, for local and/or distant diffusion, or for high surgical risk.     

Evidence of peripheral axonal neuropathy in primary restless legs syndrome

The aim of this study was to assess the risk and prognostic factors of gut perforation after orthotopic liver transplantation in children with biliary, atresia using univariate and stepwise regression analysis. Among 51 pediatric recipients who underwent transplantation because of biliary atresia after failure of portoenterostomy, 10 patients (20%) had 19 episodes of gut perforations after 14 transplantations. The median delay between transplantation and perforation was 13 days. These perforations were treated either by suture (n = 21) or ostomy (n = 11). The study of preoperative and perioperative variables showed that children with gut perforation were in surgery for a significantly longer period of time including a longer period of receiving hepatectomy and undergoing portal venous clamp. These children also needed large amounts of blood transfused during hepatectomy. After transplantation there was no difference regarding total steroid doses and early occurrence of cytomegalovirus disease between the two groups. Stepwise regression analysis identified three factors associated with the occurrence of gut perforation: duration of transplant operation, posttransplant intra-abdominal bleeding requiring reoperation, and early portal vein thrombosis. During the postoperative course, severe fungal infections were significantly more frequent in the gut perforation group. The 3-year patient survival rate was 70% in the group with gut perforation and was not different from the group without perforation (80%). This study shows that children with previous portoenterostomy carry a high risk of developing gut perforation after liver transplantation. This is especially true for those patients with the most difficult hepatectomies, which are responsible for the iatrogenic injury of the bowel. Other risk factors pointed out in this study were splanchnic congestion in case of prolonged portal venous clamp time or early portal vein thrombosis and repeated trauma of the bowel caused by reoperations. On the other hand, other well known risk factors, such as steroid therapy and viral diseases, were not involved in the occurrence of gut perforations in this study. Besides emergent surgical treatment, this type of complication requires aggressive therapy against fungal infections.     

The role of esophagectomy in the management of esophageal perforations

BACKGROUND: Despite the many advancements made in thoracic surgery, the management of patients with esophageal perforation remains problematic and controversial. METHODS: Between 1985 and 1995, 27 esophagectomies were performed for perforation of the thoracic esophagus. A retrospective review of the records of these patients was carried out, and a scoring scale developed by Elebute and Stoner to grade the severity of sepsis was applied. RESULTS: Among the 27 patients undergoing esophagectomy for a perforation, the interval between rupture and esophagectomy was less than 24 hours in only 11 patients (40.7%). Postoperative surgical complications occurred in 4 patients (14.8%) and nonsurgical complications, in 7 (25.9%). The hospital mortality rate was 3.7% (1/27). In 14 patients, primary reconstruction was performed in the bed of the excised esophagus. There were no anastomotic leaks in this subgroup. This suggests that an anastomosis between viable, well-vascularized tissues is more important for successful healing than avoidance of some degree of contamination of the adjacent mediastinum. On follow-up, which averages 41 months, 73% of patients (16/22) have neither symptoms nor complaints. CONCLUSIONS: Esophageal resection definitively eliminates the source of intrathoracic sepsis, the perforation, and the affected esophagus. Reconstruction carried out in one stage does not increase operative morbidity. Esophageal resection and reconstruction is a valid approach even in cases of spontaneous perforation in which the diagnosis is markedly delayed.     

The clinical and diagnostic characteristics of perforations in acutely bleeding gastroduodenal ulcers

Over the period 1982-1996 a total of 8822 patients with ulcerorrhagias were treated in a clinical setting. In 122 (1.4%) patients different variants of association of perforation of the bleeding ulcers (PBU) were recordable. Features of development, course, diagnosis and treatment of PBU patients were studied. Two variants of PBU development were identified: concurrently emerging perforation with ulcer bleeding--in 34 (27.9%) patients; when perforation of the ulcer emerged in 88 (72.1%) in--patients one to seven days following a bleeding event, presenting in 48 (54.5%) with bleeding recurrence, and in 40 (45.5%) patients without the above recurrence against the background of varying degrees gravity of loss of blood. As to PBU localization, 92 (75.4%) patients had the same site (in the stomach--18 subjects, pyloroduodenal region--74 ones), 30 (24.6%) patients developed simultaneously one perforating gastric or duodenal ulcer and some other ulcer bleeding. Analysis of symptoms in PBU and in 474 patients presenting with perforating ulcers without bleeding revealed varying degrees atypicalness of PBU course depending on variants of combination. A symptom complex of lesser PBU sign has been singled out, an algorithm proposed for procedures that might be helpful in making early diagnosis and planning surgical treatment to be done in a timely fashion. The suggested approach enabled the postoperative mortality to be reduced 3.5-fold (from 25% to as low as 7.1%).     

The protective effect of a cut-resistant glove liner. A prospective, randomised trial

We performed a prospective, randomised study comparing the rates of glove perforation using double latex gloving with or without a disposable protective glove liner (Paraderm) on 118 patients undergoing primary or revision arthroplasty of the hip or knee by one surgeon (FRH). The patients were randomly allocated into two groups: in group 1 an inner and outer pair of latex gloves were worn as double gloves and in group 2 the glove liner was worn between the two latex gloves. There was glove perforation in at least one outer glove in 99 operations (84%). The operating surgeon was aware of the perforation in 21 of these. There were 22 perforations of the inner glove. Group 1 had a significantly higher perforation rate per operation (p < 0.05) than group 2. Our findings show that protective glove liners significantly reduce the rate of perforation of the inner glove during hip and knee arthroplasty.     

Creativity of undergraduates with and without family history of alcohol and other drug problems

BACKGROUND: Colonoscopic surveillance is a standard procedure in many patients with long standing, extensive ulcerative colitis (UC), in order to avoid death from colorectal cancer. No conclusive proof of its benefits has been presented however. AIMS: To evaluate the association between colonoscopic surveillance and colorectal cancer mortality in patients with UC. PATIENTS: A population based, nested case control study comprising 142 patients with a definite UC diagnosis, derived from a study population of 4664 patients with UC, was conducted. METHODS: Colonoscopic surveillance in all patients with UC who had died from colorectal cancer after 1975 was compared with that in controls matched for age, sex, extent, and duration of the disease. Information on colonoscopic surveillance was obtained from the medical records. RESULTS: Two of 40 patients with UC and 18 of 102 controls had undergone at least one surveillance colonoscopy (relative risk (RR) 0.29, 95% confidence interval 0.06 to 1.31). Twelve controls but only one patient with UC had undergone two or more surveillance colonoscopies (RR 0.22, 95% confidence interval 0.03 to 1.74), indicating a protective dose response relation. CONCLUSION: Colonoscopic surveillance may be associated with a decreased risk of death from colorectal cancer in patients with long standing UC.     

Clinical observation of the temporal association between crack cocaine and duodenal ulcer perforation

HYPOTHESIS: To determine if a cause-effect relationship exists between crack cocaine use and duodenal ulcer perforation (DUP). PATIENTS AND METHODS: A retrospective study was conducted of all patients undergoing emergency surgical management for peptic ulcer disease over a 6-year period at a large inner-city municipal teaching hospital. The hospital records of 78 consecutive patients presenting with complications of peptic ulcer disease between April 1990 and April 1996 were reviewed. Group A (n = 24) consisted of patients with confirmation of crack cocaine usage within 8 hours of clinical presentation; group B (n = 54) consisted of patients with no antecedent history of crack cocaine use. Demographic data, timing of drug use, clinical presentation, laboratory and radiographic findings, toxicology screening, operative findings, and postoperative course were compared between the two groups. RESULTS: Both groups revealed a similar gender distribution, tobacco use, prior peptic ulcer symptoms, and laboratory findings. Group A patients were younger (t test, P = 0.01) and more likely to present with perforation, whereas patients in group B presented with a combination of symptoms (chi square, P = 0.03). Duodenal ulcer perforation was present in 75% of patients in group A compared with 46% of patients in group B (chi square, P = 0.04). Group B patients had a significantly longer hospital stay compared with those in group A (t test, P = 0.01). Both crack cocaine and alcohol are independent predictors of duodenal ulcer perforation. CONCLUSIONS: Patients with recent use of crack cocaine and/or alcohol are more likely to present with duodenal perforations. Although a temporal association between crack cocaine use and duodenal ulcer perforation was demonstrated, this study does not confirm a cause-effect relationship. A prospective cohort study is needed to clarify the pathogenesis of this potential cause-effect relationship.     

Stress urinary incontinence. Our experience with its treatment using the transvaginal colposuspension technique (Raz I and II)

Presentation of our experience in the surgical treatment of urinary stress incontinence, with transvaginal colposuspension techniques, specifically those described by S. Raz and known as Raz I and Raz II. Over a 24-month period, 25 transvaginal colposuspensions (22 Raz I and 3 Raz II) were performed. The results achieved were 21 patients (84%) have recovered, while 4 (16%) remain incontinent, 3 of them referring improvement and 1 without improvement, after a follow-up of 12 to 36 months. With regard to complications, there has been 5 cases (20%) of postoperative retention, one vesical perforation while passing the needles, and a vesicle perforation during vaginal dissection of the retropubic space.     

Stercoral perforation of the normal colon: report of five cases

A series of five consecutive patients with stercoral perforation of the colon is presented. Four of the patients had free perforation and one had an abscess between the splenic flexure, spleen and surrounding organs, a yet unreported entity. All patients underwent emergency surgery including laparostomy with repeated explorations and lavages in two of them. The ethiology, pathophysiology and treatment of the condition are updated. A graphic algorithm for decision-making in appropriately dealing with stercoral perforation of the colon is proposed.
