Laparoscopic lymphocele fenestration in gynaecological cancer patients after retroperitoneal lymph node dissection as a first-line treatment option.

OBJECTIVE: To evaluate laparoscopic lymphocele fenestration (LLF) as a first-line treatment in gynaecological cancer patients with a history of retroperitoneal lymph node dissection (LND). DESIGN: Retrospective cohort study. SETTING: A tertiary referral centre. POPULATION: Patients who underwent LLF between January 2001 and December 2010 for a symptomatic lymphocele following retroperitoneal LND. METHODS: Surgical outcomes of 102 patients who underwent LLF at our hospital between January 2001 and December 2010 were analysed. Patients were identified using hospital database search software, and hand-written and electronic charts were reviewed. MAIN OUTCOME MEASURES: Outcomes included operating time, blood loss, conversion rate, intra- and postoperative complication rates, hospital stay and relapse rate. RESULTS: A total of 132 lymphoceles were fenestrated in 102 patients. The mean duration of surgery was 115.6 minutes and the average intraoperative blood loss per patient was 146 ml. The overall conversion rate to laparotomy was 7.8%. Intra- and postoperative complication rates were estimated at 9.8 and 5.9%, respectively. The rate of intraoperative and postoperative complications was significantly higher in patients after pelvic plus paraaortic LND (23.8%), compared with those after pelvic LND only (3.6%; P > 0.01). The mean follow-up time was 60.4 months and a total of seven symptomatic recurrences of lymphoceles were observed (a recurrence rate of 6.9%). CONCLUSIONS: For the treatment of symptomatic lymphoceles, LLF has previously been established as an efficient first-line treatment option in a post-transplant context. Our data suggest that these favourable results for LLF may be transferable to gynaecological cancer patients.

Treatment of endometriosis of uterosacral ligament and rectum through the vagina: description of a modified technique.

BACKGROUND: Endometriosis is common in women of childbearing age, whereas involvement of the rectosigmoid requiring resection is rare. Laparoscopy has become a standard procedure in the management of endometriosis. The optimum way to diagnose endometriosis is by direct visualization of the implants. Usually for the removal of the specimen, an additional larger abdominal incision is needed. METHODS: Here we report on cases of four patients with a uterosacral ligament and rectal endometriosis who were successfully treated with combined laparovaginal resection, using a modification of an existing technique. They had been complaining of rectal bleeding and lower abdominal pain in relation to their menstrual cycle. The aim of this technique is to achieve a careful and margin-free resection of the area involved. This can be done without any large incisions of the abdominal wall. The hypogastric nerves remain preserved on both sides. RESULTS: The intra- and post-operative courses were uneventful. No blood transfusions were needed. Haemoglobin decrease was usually < or =1 mmol/l. The average tumour diameter was 3.5 cm. CONCLUSIONS: Our technique circumvents a larger abdominal incision. This combined laparoscopic-transvaginal approach, avoiding the extension of port-site incisions, represents a viable option for the treatment of bowel endometriosis.

Sentinel lymph node biopsy in vulvar cancer: a pilot study.

BACKGROUND: The aim of the pilot study was to assess the feasibility, efficacy, and accuracy of the sentinel lymph node biopsy (SLNB) procedure in vulvar cancer. PATIENTS AND METHODS: From February 2003 to March 2007, 17 patients with vulvar cancer, clinical Stages I and II, underwent SLN (sentinel lymph node) detection, followed by a complete inguinal-femoral lymphadenectomy. Demographic, surgical, and pathologic data on all patients were reviewed. RESULTS: 17 patients underwent the SLNB procedure. Sixteen had vulvar carcinoma and one patient suffered from melanoma of the vulva. Midline localisation was done in 11 patients (64.7%). A total of 371 lymph nodes were resected. The median number of removed lymph nodes was 15 (range 2 to 81). Nineteen lymph nodes were positive with a maximum of six in one patient. Overall the detection rate for the sentinel lymph node was 88.2% (15 out of 17). One of the two patients with a non detectable sentinel node had positive lymph nodes. Eighty lymph nodes were detected as the sentinel node. The median number of sentinel nodes was five (range 0 to 11). Seventeen sentinel nodes were involved. The sentinel node was negative in nine patients; one of these had involved lymph nodes. CONCLUSIONS: SLNB is feasible and safe to perform in vulvar cancer. Further evaluation is needed until new guidelines allow the use in early-stage vulvar cancer.

Laparascopically assisted vaginal resection of rectovaginal endometriosis.

BACKGROUND: We wanted to establish a technique of laparoscopically assisted radical vaginal surgery for deep endometriosis of the rectovaginal septum with extensive rectal involvement. TECHNIQUE: The procedure is started by vaginally excising the involved area which is left on the rectum, followed by bilateral dissection of the pararectal and retrorectal spaces. Para- and retrosigmoido-rectal spaces are developed laparoscopically along the coccygeosacral bone and medially to the pelvic splanchnic nerves toward the para- and retrorectal openings that were made transvaginally. Rectal transection is done with a laparoscopic stapling device caudal to the endometriotic lesion. Using a suprapubic minilaparotomy, the bowel is transected cranial to the lesion and reintroduced into the abdomen, and a transanal circular stapler anastomosis is done. EXPERIENCE: Thirty-four women had this procedure. The mean distance of the anastomosis was 4 cm above the anus. None required ileostomy or colostomy and no major complications were noted. CONCLUSION: The combination of laparoscopic and vaginal approaches is useful for removing extensive endometriotic infiltration of the rectosigmoid; bladder and rectal function and fertility can be preserved.

Prophylactic bilateral salpingectomy (PBS) to reduce ovarian cancer risk incorporated in standard premenopausal hysterectomy: complications and re-operation rate.

PURPOSE: Hysterectomy for benign conditions can be combined with bilateral salpingectomy to prevent re-intervention for malignant or benign fallopian tube pathologies. The objective of this study was to evaluate the benefit of prophylactic bilateral salpingectomy (PBS) in standard hysterectomy in premenopausal women. METHODS: This retrospective cohort study included all premenopausal patients at our institution who underwent laparoscopically assisted vaginal hysterectomy (LAVH) without oophorectomy for benign pathologies between 2001 and 2007 [PBS group (LAVH + PBS), 2006-2007; non-PBS group (LAVH without PBS), 2001-2005]. Electronic and paper-based files as well as questionnaire responses were analyzed. In 2010, a survey on patients of a non-BRCA background with and without PBS was requested to complete a standardized questionnaire. Data were analyzed for differences between both subgroups regarding surgical outcome and adnexal pathologies as reported in the postoperative follow-up. RESULTS: Surgical outcomes of 540 patients (PBS: 127; non-PBS: 413) revealed no difference between groups. No preneoplastic or malignant lesions were diagnosed in the fallopian tubes. Follow-up (non-PBS 92 months, PBS 55 months; p < 0.01) responses from 295 (54.6 %) patients showed a higher incidence of benign adnexal pathologies in the non-PBS group (26.9 vs. 13.9 %; p = 0.02). The rate of LAVH-related surgical re-intervention was higher in the non-PBS group (12.56 vs. 4.16 %; p = 0.04). No malignant neoplasm was reported in the cohort. CONCLUSIONS: PBS did not increase the complication rate and reduced the incidence of adnexal pathologies requiring surgical re-intervention. Prospective trials should clarify the impact of PBS on cancer mortality.

[Intraluminal hypertension as a pathogenetic factor of acute pancreatitis in the rat (author's transl)]. / Die duktale Obstruktion als pathogenetischer Faktor der akuten Pankreatitis. Eine tierexperimentelle Untersuchung.

By the use of various experimental procedures with rats, the significance of intraluminal hypertension, caused by ductal obstruction, reflux of bile and duodenal reflux were considered with regard to their capacity for producing pancreatitis. The extent of the histological changes in the pancreas after 48 hours as well as the period of survival in the individual experimental groups served as the parameters for the comparison. The results show that the rise in intraluminal pressure is alone enough to produce acute pancreatitis. It follows from this that rise of pressure in the duct system caused by ductal obstruction may be the triggering factor in the induction of pancreatitis. Reflux of bile, bacterial colonisation of the pancreas by duodenal reflux as well as activation of proteolytic enzymes were not necessary a prior factors but ones which have an aggravating effect in the development of the disease.

Is the decision for colorectal resection justified by histopathologic findings: a prospective study of 100 patients with advanced ovarian cancer.

OBJECTIVE: We compare the indication for colorectal resection in patients with advanced ovarian cancer with histopathologic findings. We describe the effect on pelvic control and morbidity associated with surgery. METHODS: Between February 1995 and March 2001, 100 patients with FIGO stage IIIc ovarian cancer underwent pelvic en bloc resection with excision of the rectosigmoid colon as part of primary or secondary cytoreductive surgery. Decision for resection was made by the surgeon when tumor involvement of the cul-de-sac was suspected. Rectosigmoid infiltration was histopathologically defined as infiltration of the serosa or deeper. RESULTS: In 73 of 100 patients (73%) tumor involvement of the rectum was confirmed histopathologically: infiltration of the serosa in 28 (28%) patients, infiltration of the muscularis in 31 (31%) patients, and infiltration of the mucosa in 14 (14%) patients; in 27 (27%) patients no infiltration was found. Histopathologically confirmed pelvic R0 resection was achieved in 85 (85%) patients. In 11 (11%) patients the pelvic resection margins were tumor-involved and in four (4%) patients visible parametric tumor remained in situ. Pelvic recurrence occurred in 4 (4.7%) of 85 optimally debulked patients compared with 9 (60%) of 15 patients with suboptimal pelvic resection status (P < 0.05). End colostomy could be prevented in 94 (94%) of 100 patients. CONCLUSION: Pelvic en bloc surgery with rectosigmoid resection was justified by histopathologic outcome since deperitonealization with preservation of the rectosigmoid would have left tumor in situ in 73% of patients with suspected cul-de-sac involvement.
