Comparison of systemic and mucosal priming for mucosal immune responses to a bacterial protein antigen given with or coupled to cholera toxin (CT) B subunit, and effects of pre-existing anti-CT immunity

The advantages of the laparoscopic mode of access for hysterectomy include shorter recovery time and less pain and scarring. The laparoscopic component of the hysterectomy is usually combined with a vaginal component. The relative proportions of the procedure, performed laparoscopically and vaginally, vary considerably between surgeons. The main problem associated with the laparoscopic approach is to ensure adequate hemostasis while avoiding damage to the urinary tract. A variety of differing techniques have been developed in attempts to ensure the safe and efficient removal of the uterus laparoscopically.     

Abdominal radical trachelectomy: a new surgical technique for the conservative management of cervical carcinoma

Traditionally radical hysterectomy has formed the mainstay of treatment for early stage cervical carcinoma. More recently radical trachelectomy and laparoscopic lymphadenectomy have been introduced to allow preservation of fertility. We present a new approach to fertility-sparing surgery, namely abdominal radical trachelectomy. The technique is similar to a standard radical hysterectomy and lymphadenectomy. In our technique the ovarian vessels are not ligated and, following lymphadenectomy and skeletonisation of the uterine arteries, the cervix, parametrium and vaginal cuff are excised. The residuum of the cervix is then sutured to the vagina and the uterine ateries re-anastomosed.     

Laparoscopy-assisted radical vaginal hysterectomy modified according to Schauta-Stoeckel

In laparoscopy-assisted radical vaginal hysterectomy, laparoscopy is used to develop the paravesical and pararectal spaces. The cardinal ligament is isolated and cut after bipolar coagulation to the level of the deep uterine vein. By the vaginal approach, the ureters are identified before their entry into the bladder pillar. The uterine vessels are pulled down until their laparoscopically coagulated ends become visible. After incision of the vesicocervical reflection, the uterine fundus is grasped and developed (D?derlein maneuver). The lower cardinal and uterosacral ligaments are exposed by pulling the cervix and fundus uteri to the contralateral side. The cardinal and uterosacral ligaments are dissected and ligated, and the specimen is removed. We combined laparoscopic lymphadenectomy with radical vaginal hysterectomy in 33 women with cervical cancer. The mean operating time was 80 minutes for the vaginal phase and 215 minutes for the laparoscopic phase, including paraaortic and pelvic lymphadenectomy and preparation of the cardinal ligaments. Blood transfusions were necessary in four women. Three patients sustained injury to the bladder, one patient to the left ureter, and another patient to the left internal iliac vein. Repair was achieved at primary surgery for all intraoperative complications. No fistula was observed. The patients had fully recuperated after a mean of 28 days. The laparoscopy-assisted Schauta-Stoeckel approach may prove to be a safe alternative to conventional radical abdominal hysterectomy.     

Laparoscopic hysterectomy. Supracervical vs. assisted vaginal

Twenty cases of laparoscopic supracervical hysterectomy performed by operative laparoscopy without vaginal assistance were retrospectively compared to 232 cases of laparoscopically assisted vaginal hysterectomy reported in the literature. The specimens were morcellated intraabdominally and removed through the umbilicus. This is the first reported series of this technique with intraabdominal morcellation, which emphasizes cosmetic considerations and remains within the confines of the umbilicus. The postoperative hospitalization time ranged from 3.75 to 22.2 hours. On the second postoperative day, 10% of the patients returned to work, and 15% were able to drive. Patients resumed normal activity in an average of 5.6 days after surgery. As compared to laparoscopically assisted vaginal hysterectomy, there was a decrease in morbidity, blood loss and recovery time. Prolonged anesthesia from the longer operating time was clinically insignificant in terms of the patients' recovery. By decreasing the disability from hysterectomy from six weeks to one, the procedure provided financial savings through work time gained.     

Laparoscopy-assisted and -prepared hysterectomy. A series of 80 cases

OBJECTIVE: Our objective was to determine the interest of laparoscopic assisted vaginal hysterectomy. STUDY DESIGN: Between January 1991 to december 1994, 80 patients had laparoscopically assisted vaginal hysterectomy. We reviewed with particular emphasis characteristic indications, complications. RESULTS: Eighty were performed as laparoscopically assisted vaginal hysterectomy. 14 patients (17.5%) had laparotomy conversion; because of size of uterus in 3 cases, suspected ovarian tumor in 3 cases. Pelvic adherences in 4 cases, urinary tract injuries in 1 case, hypercapnia in 1 case, hemorrhage in 2 cases. 9 patients experienced febrile morbidity and 1 urinary infection. 1 patient received 2 units of packed red blood cells. The hospital stay was 5 days for laparoscopically assisted vaginal hysterectomy versus 5.9 for laparotomic hysterectomy. CONCLUSION: Laparoscopically assisted vaginal hysterectomy offers a technique to convert certain abdominal hysterectomies into vaginal hysterectomies with a 17.5% laparoconversion rate.     

Is laparoscopic hysterectomy a waste of time?

Laparoscopic hysterectomy (LH) is a way to avoid laparotomy. However, there is evidence that most women treated by abdominal hysterectomy are suitable for vaginal surgery. To test this hypothesis, and to determine the relative merits of laparoscopic and vaginal hysterectomy (VH) and the best technique for LH, we prospectively studied 98 women who had relative contraindications for vaginal surgery by traditional criteria. 75 underwent LH and 23 VH. The LH group included 22 women who had been assigned to this route of surgery as part of a prospective randomised controlled comparison with VH (23 women). Surgery was completed with the intended technique in 93.9% of cases. 5 women in the LH group (6.7%) and 2 in the VH group required laparotomy or additional procedures. In the prospective randomised study LH took longer than VH (mean duration 131 vs 77 min). VH was the faster procedure, irrespective of uterine size and need for oophorectomy. With LH, the operative time increased as more of the hysterectomy was carried out with laparoscopic rather than vaginal dissection. Complication rates, blood loss, analgesia requirements, and recovery were similar for the two techniques. Our study confirms that most hysterectomies could be performed vaginally, and that LH is a much slower procedure. If LH is done, it should be converted to a vaginal procedure as early as possible to reduce the overall operating time. LH does seem to be a waste of time for most patients.     

The importance of hypergastrinemia in the diagnosis of Biermer''s disease in the adult

Thirty-three patients were selected for laparoscopic hysterectomy and operated on in the Department of Obstetrics, Gynecology and Reproductive Medicine of Clermont-Ferrand University Hospital. Surgical techniques included blunt dissection with scissors and bipolar coagulation to achieve hemostasis. A case was considered successful when all the uterine vessels were treated by laparoscopy. Twenty-four cases were completed laparoscopically (72.7%). None of these patients had postoperative bleeding; 22 had an uneventful postoperative recovery. Nine procedures were converted to laparotomy (27.3%), five because of a difficult or unsatisfactory hemostasis. We conclude that in selected cases, a total hysterectomy can be performed safely by experienced laparoscopists. Further technological progress is necessary to make this procedure more acceptable. Its value as compared to the others will have to be demonstrated.     

An ultrasonic scalpel for laparoscopic gynecologic surgery

In order to obtain good results in laparoscopic surgery the surgeon should be well trained and experienced and the equipment perfect. The recent innovation in laparoscopic surgery is the ultrasonically activated scalpel. Scissors make the working part of scalpel with one hand vibrating 55,000 Hz in a second. The effect reflects in braking hydrogen links and denaturation of proteins in instant haemostasis and coagulation in blood vessels, and there is no need of tying them up. Practically, there is no damaging of the surrounding tissues. The technique is easy to use. When performing laparoscopic vaginal hysterectomy and adnexectomy the ligamentum infundibulopelvicum and ligamentum rotundum are cut, and there the blood vessels are not thicker than 3 millimeters. As these ligaments are easy to reach with ultrasonically activated scalpel, we can say that this instrument is the ideal option for laparoscopic vaginal hysterectomy.     

Tissue expander complications in the pediatric burn patient

OBJECTIVES: The main purpose of our study was to identify the patient characteristics of women undergoing hysterectomy and to estimate the proportion of hysterectomies that could be done vaginally by recognized surgical techniques. STUDY DESIGN: The records of 500 women who underwent hysterectomy were reviewed. The characteristics of patients without an absolute contraindication to vaginal hysterectomy were analyzed. RESULTS: Overall, 96 (19.2%) of our study group underwent vaginal hysterectomy. A total of 382 (76.4%) women were judged not to have an absolute contraindication to this route. The most frequent characteristics of this group were lack of uterine prolapse (76.4%), a myomatous uterus (44.5%), and a need for oophorectomy (43.2%). We did not exclude women who did not have significant uterine prolapse or a history of pelvic surgery or pelvic tenderness and we included those requiring oophorectomy or with a uterine size up to that of 14 weeks' gestation; with these criteria more than two thirds of the entire study population could undergo vaginal surgery. CONCLUSIONS: To maximize the proportion of hysterectomies performed vaginally, gynecologists need to be familiar with surgical techniques for dealing with nonprolapsed uteri, uterine leiomyomas, and vaginal oophorectomy.     

Costs and charges associated with three alternative techniques of hysterectomy

BACKGROUND: Many hysterectomies are now performed by a laparoscopically assisted vaginal technique. This procedure is controversial, partly because of concern about cost. We studied hospital charges and costs for the procedure as compared with those for total abdominal hysterectomy and total vaginal hysterectomy in clinically similar groups of patients. METHODS: From hospital-discharge data and patients' charts, we identified hysterectomies performed in 1993 and 1994 by 96 surgeons at a community teaching hospital to treat benign conditions. The patients were grouped according to the surgical procedures performed in conjunction with the hysterectomy. Data on hospital charges and cost-to-charge ratios for 64 hospital cost centers were used to assess charges and costs for specific resources, as well as for the hospitalization overall. RESULTS: Of 1049 patients studied, 26 percent underwent laparoscopically assisted vaginal hysterectomy, 54 percent underwent abdominal hysterectomy, and 20 percent underwent vaginal hysterectomy. The average hospital stays were 2.6, 3.9, and 2.9 days, respectively, and the mean total charges (facility charges plus professional fees) for the hospitalizations were $6,116, $5,084, and $4,221 (P<0.001 for the comparison of the laparoscopic technique with both other techniques). The mean facility costs were $4,914, $3,954, and $3,116, respectively (P<0.001 for the same comparison), with similar findings in all subgroups. The higher charges and costs for laparoscopically assisted vaginal hysterectomy were due to higher supply costs, particularly when disposable supplies were used, and to longer operating-room time. CONCLUSIONS: Despite shorter hospital stays, in-hospital charges and costs for laparoscopically assisted vaginal hysterectomy are higher than for either alternative procedure, because of the disposable supplies that are typically used and the longer operating-room time.     

Laparoscopically assisted vaginal hysterectomy

OBJECTIVE: To report our experience with laparoscopically assisted vaginal hysterectomy (LAVH) and evaluate the advantages of LAVH. STUDY DESIGN: From January 1991 to August 1992, 176 LAVHs were performed at the Department of Obstetrics and Gynecology, College of Medicine, Chung-Ang University, Seoul, Korea. The indications for LAVH, based on the preoperative diagnosis, were uterine myomas, dysmenorrhea, chronic pelvic inflammatory disease or pelvic pain, dysfunctional uterine bleeding and cervical intraepithelial neoplasia (in order of frequency). RESULTS: Patients had concomitant procedures, including incidental appendectomy, posterior wall repair, pelvic adhesiolysis and salpingo-oophorectomy. Bipolar forceps were used to compress and desiccate vessels. The Nd-YAG laser, scissors and/or unipolar electrode were used for tissue division, excision of adhesions and cutting. The intraoperative complications were bladder perforation, massive hemorrhage and inferior epigastric vessel injury (one case each). The postoperative complications were infection, voiding difficulty, febrile morbidity, pelvic abscess, incisional hernia, vaginal vault bleeding and peroneal nerve palsy (one case each). CONCLUSION: Hysterectomy can be safely performed vaginally assisted by operative laparoscopy by well-trained laparoscopists, resulting in reduced surgical morbidity, blood loss, postoperative discomfort, recovery time and hospitalization.     

Guidelines to determine the route of oophorectomy with hysterectomy

OBJECTIVES: Our purpose was to determine whether there is adequate visibility and access for transvaginal oophorectomy in most patients and the success rate of the transvaginal approach. The final goal was to establish objective guidelines for choosing the route of oophorectomy with hysterectomy. STUDY DESIGN: Patients underwent laparoscopy-assisted vaginal hysterectomy (n = 91) or vaginal hysterectomy (n = 875). Ovarian removal, either unilateral (n = 97) or bilateral (n = 187), was carried out for clinical or prophylactic reasons. The accessibility of the ovaries for transvaginal removal was assessed by stretching the infundibulopelvic ligament and grading the position of the ovaries from 0 (no descent) to III (descent past the hymenal ring with traction). RESULTS: In 158 patients transvaginal bilateral oophorectomy was performed without laparoscopic assistance. In another 29 patients bilateral transvaginal oophorectomy was performed with laparoscopy-assisted vaginal hysterectomy, and prophylactic bilateral oophorectomy by the transvaginal route was successful in all but 1 of 143 patients with ovaries of grade I or higher. In 20 patients laparoscopic lysis of adhesions was necessary to permit transvaginal oophorectomy. Ninety-seven patients underwent transvaginal unilateral oophorectomy, 74 with conventional vaginal hysterectomy and 23 with laparoscopy-assisted vaginal hysterectomy. Among the patients not having oophorectomy, all ovaries had sufficient mobility to have been removed transvaginally. CONCLUSION: Good surgical practice dictates that visibility and accessibility be the primary criteria for selecting the route of oophorectomy with hysterectomy. In most patients the ovaries are visible and accessible to transvaginal removal.     

Initial experiences and outcome of gasless laparoscopic pelvic lymph node excision combined with Schauta vaginal radical hysterectomy in stage IB cervix carcinoma

In 11 patients with a cervical cancer stage IB a gasless laparoscopic pelvic lymph node dissection in combination with a vaginal radical Schauta-Amreich-hysterectomy was performed. The technique of the gasless lymph node dissection with the Laparolift (ORIGIN Medsystems, Menlo Park) is described. Because of the advantages of this technique (ability to use conventional and endoscopic instruments, perform irrigation and suction, dot with sponge sticks, change instruments quickly, prepare and remove lymph nodes without influence on visibility) it was possible to obtain a radicality (45 lymph nodes-median value) according to oncological standards for an abdominal radical Wertheim hysterectomy. If the radicality is equivalent to a Wertheim hysterectomy the combination of the radical vaginal Schauta-Amreich-hysterectomy and the gasless laparoscopic pelvic lymph node dissection offers a real alternative to the abdominal Wertheim hysterectomy because of low postoperative morbidity and quick mobilisation.     

Necrotizing fasciitis following laparoscopic surgery. Case report and review of the literature

Necrotizing fasciitis is a rare and potentially fatal infection characterized by rapid and progressive involvement of the fascia and subcutaneous tissues. Early diagnosis, aggressive initial debridement followed by planned redebridements in conjunction with nutritional support and antibiotics remain the mainstay of therapy. We present a case of necrotizing fasciitis of the abdominal wall following a laparoscopically assisted vaginal hysterectomy. Literature is reviewed and discussed with reference to this catastrophic infection in the age of laparoscopic surgery.     

Vaginal endoscopic oophorectomy with vaginal hysterectomy: a simple minimal access surgery technique

The main advantage of laparoscopic assisted vaginal hysterectomy (LAVH) is ease of access to the ovaries; despite this, LAVH is infrequently performed due to the inherent difficulty of the technique. Lower morbidity, shorter length of surgery, reduced hospital stay and more rapid recovery are the main advantages of vaginal hysterectomy, but one of its limitations is the accessibility of the ovaries. Three methods of vaginal endoscopic oophorectomy following vaginal hysterectomy are described in this paper. Endoscopic vaginal oophorectomy was successfully performed during 82 cases of vaginal hysterectomy and the results show that the technique is simple, safe and easy to learn, and an alternative to laparotomy and LAVH in the absence of pelvic adhesions.     

Laparoscopic distal resection of the pancreas with the preservation of the spleen

Management of the pancreatic diseases is still a challenge to the laparoscopic technique. Some experience has been gained in the laparoscopic exploration of the pancreas and staging in cancer. Anatomically the accessibility of the distal pancreas provides the laparoscopic approach technically feasible. Patient and method: A case of insuloma in the tail of the pancreas is presented, where distal pancreatic resection was performed laparoscopically with the preservation of the spleen. In a 55 years old female patient with typical clinical symptoms of hyperinsulinism CT identified a 3 cm large solid tumor in the tail of the pancreas. Complete mobilization of the distal pancreas was enhanced by the use of an ultrasonic dissector (UltraCision). The pancreas is detached from the splenic hilum after dividing the spleen vessels. The pancreas is transected proximally by laparoscopic linear stapler. Preservation of the short gastric vessels provides the necessary blood supply of the spleen following division of the splenic artery and vein. Thus removal of the spleen is not a necessary step in this procedure. The operation was carried out within 4.5 hours. Postoperative course was uneventful, the patient left the hospital on the 5th postoperative day. Advantages of the procedure were the earlier mobilization and shorter recovery time, less postoperative pain. The procedure can be safely performed with a good experience in both pancreatic and laparoscopic surgery.     

A new uterine manipulator for operative laparoscopic hysterectomy

A new, reusable uterine manipulator was developed to facilitate pelviscopic surgery and laparoscopic hysterectomy. The device is weighted to hold the uterus in an anteverted position and allow easy access to the cul-de-sac. It is spring loaded to create a tight seal for tubal insufflation. The instrument is calibrated in centimeters and has a sliding cervical plug that allows it to be inserted into the fundus to a depth of 15 cm for uterine manipulation during laparoscopic hysterectomy. The spring-loading mechanism holds the device firmly to the cervical tenaculum regardless of the depth of penetration, and rotates 180 degrees for use in the retroverted uterus.     

Indications for laparoscopic surgery in cases of gynecological malignancies (endometrial cancer)

The role of surgery in the treatment of patients with invasive cervical cancer is undisputed, but how radical surgery should be is debatable. Every case requires detailed knowledge of the development and spread of cervical cancer. Tumor volume is the most important diagnostic factor in cervical cancer and also correlates with vascular invasion and lymph node involvement. As radical hysterectomy requires in cervical cancer besides the laparoscopically easy performable lymphadenectomy also the resection of parametria with sceletonisation of ureters we started to treat endometrial cancer with a combined laparoscopic and vaginal approach. In patients with the suspicion of stage I endometrial cancer prior to laparoscopic staging, the prerequisites of histological grading with ploidy and measurement of monoclonal antibodies were performed. All patients underwent a general check with radiography, computer tomography, liver scan, bone scan and lymphography. The performance of lymphadenectomy in cases of stage I endometrial cancer remains a controversial subject. We believe that laparoscopic assisted surgical staging of stage I endometrial cancer is an attractive alternative to the traditional laparotomy-surgical approach. The change from laparotomy to a laparoscopic assisted vaginal approach allows for a similar success rate with the less invasive approach. No complications occurred in this series and the results of our pilot study were satisfactory.     

Enzymatic phosphorylation of soy globulins by the protein kinase CK2. Determination of the phosphorylation sites of beta-conglycinin alpha subunit by mass spectrometry

Being quite experienced in the field of gynaecologic surgery and hysterectomies especially, being familiar with recent innovations in laparoscopic surgery and also having some own experience in laparoscopic surgery, the authors discuss the advantages and disadvantages of all surgical methods of hysterectomy. Comparing the techniques, the duration, bearing in mind the the risks, overall costs and all other surgical details, the authors concluded that laparoscopically assisted vaginal hysterectomy is the best choice because it is the least invasive, less risky, no scars are left, the postoperative recovery is quick, there are numerous indications for it, the preparation obtained as a whole can be used for further clinical examination. The only disadvantage is it is too costly and sometimes the operation itself lasts too long, so it should not be applied in some cases.     

Vaginal hysterectomy for the large uterus

OBJECTIVE: To assess the feasibility and safety of performing vaginal hysterectomy on enlarged uteri the equivalent of 14 to 20 weeks of gestation in size. DESIGN: A prospective observational study. SETTING: The Royal Free Hospital, London. PARTICIPANTS: Fourteen consecutive women undergoing vaginal hysterectomy for uterine fibroids up to 20 weeks in size. INTERVENTIONS: Vaginal hysterectomy with or without bilateral salpingo-oophorectomy or oophorectomy. MAIN OUTCOME MEASURES: Uterine size and weight, techniques used to reduce uterine size, surgical outcome, operative time, estimated operative blood loss, intra- and post-operative complications, duration of hospitalisation. RESULTS: The mean uterine size was 16.3 weeks (range 14 to 20 weeks). All hysterectomies were completed successfully by the vaginal route. The uteri weighed 380 to 1100 g, with a mean of 638.7 g. Bisection combined with myomectomy and morcellation were used in most cases to obtain reduction in uterine size, whereas coring was only utilised in two cases. The mean operating time was 84.3 min with a range of 30 to 150 min. The only complications were transient haematuria (n = 6) and superficial vaginal grazes (n = 5). One of the women required a blood transfusion. The mean post-operative hospital stay was 3.7 days (range 2 to 9 days). CONCLUSION: Enlargement of the uterus to a size equivalent to 20 weeks of gestation should no longer be considered a contraindication to vaginal hysterectomy. Many more hysterectomies should be carried out vaginally without resorting to abdominal or laparoscopic surgery.
