Background:To evaluate surgical outcome and survival benefit after quaternary cytoreduction (QC) in epithelial ovarian cancer (EOC) relapse.Methods:We systematically evaluated all consecutive patients undergoing QC in our institution over a 12-year period (October 2000–January 2012). All relevant surgical and clinical outcome parameters were systematically assessed.Results:Forty-nine EOC patients (median age: 57; range: 28–76) underwent QC; in a median of 16 months (range:2–142) after previous chemotherapy. The majority of the patients had an initial FIGO stage III (67.3%), peritoneal carcinomatosis (77.6%) and no ascites (67.3%). At QC, patients presented following tumour pattern: lower abdomen 85.7% middle abdomen 79.6% and upper abdomen 42.9%. Median duration of surgery was 292 min (range: a total macroscopic tumour clearance could be achieved. Rates of major operative morbidity and 30-day mortality were 28.6% and 2%, respectively.Mean follow-up from QC was 18.41 months (95% confidence interval (CI):12.64–24.18) and mean overall survival (OS) 23.05 months (95% CI: 15.5–30.6). Mean OS for patients without vs any tumour residuals was 43 months (95% CI: 26.4–59.5) vs 13.4 months (95% CI: 7.42–19.4); P=0.001. Mean OS for patients who received postoperative chemotherapy (n=18; 36.7%) vs those who did not was 40.5 months (95% CI: 27.4–53.6) vs 12.03 months (95% CI: 5.9–18.18); P<0.001.Multivariate analysis indentified multifocal tumour dissemination to be of predictive significance for incomplete tumour resection, higher operative morbidity and lower survival, while systemic chemotherapy subsequent to QC had a protective significant impact on OS. No prognostic impact had ascites, platinum resistance, high grading and advanced age.Conclusion:Even in this highly advanced setting of the third EOC relapse, maximal therapeutic effort combining optimal surgery and chemotherapy appear to significantly prolong survival in a selected patients ‘group'.

The outcome of bile duct reconstruction may be worse in the presence of combined biliary and vascular injuries than in patients with an intact blood supply of the bile ducts. We recommend arterial reconstruction when possible in early recognized injuries to prevent late strictures. Short-term follow-up is most important for early recognition of postoperative strictures and to avoid further complications such as secondary biliary cirrhosis.

Our data show that patients with elevated BMI have slightly more complications and an identical long term survival as patients with normal body weight.

Laparoscopic appendectomy is a safe and effective method to treat acute appendicitis in pregnant women regardless of the trimester. For the best outcome the operation should be performed in a center where surgeons, perinatologist, obstetricians and anesthesiologists work together as a part of an interdisciplinary team.
