The objective of this study was to examine the rate of and indications for readmission in patients with advanced staged ovarian cancer undergoing rectosigmoid resection and primary anastomosis, an important quality metric. A retrospective review was conducted of patients with primary ovarian cancer who underwent rectosigmoid resection as part of cytoreductive surgery between July 2003 and July 2014. Univariate analysis identified rates and predictors of readmission. Fifty patients were eligible for analysis. The unanticipated 30-day readmission rate was 18% (n = 9). Of those readmitted less than 30 days from date of discharge, 3 were readmitted more than once, making 14 total readmissions. A total of 21 indications for readmission were reported, with the most common being: infection (23.8%, n = 5); thromboembolic events (19%, n = 4); and severe malnutrition (14.3%, n = 3). The median time to readmission was 14 days (range, 2-26). There were no deaths within 30 days of surgery in this cohort.IMPACT STATEMENTWhat is already known about the subject? Unanticipated 30-day readmission rates are reported to be between 12 and 20% among patients undergoing cytoreductive surgery for the management of ovarian cancer. The relative contribution of rectosigmoid resection at the time of cytoreductive surgery to readmission is not well studied.What do the results of this study add? In the examined cohort, the unanticipated 30-day readmission rate following rectosigmoid resection with primary reanastomosis at the time of cytoreductive surgery is 18%, similar to the readmission rate for patients undergoing cytoreductive surgery, in general. While the sample size is limited, the perioperative complications in this cohort appear similar to those of patients undergoing cytoreductive surgery.What are the implications of these findings for clinical practice and/or further research? Efforts to reduce unanticipated 30-day readmission following cytoreductive surgery is warranted. Future studies may benefit from multi-centre approaches and prospective data collection, while simultaneously assessing the impact of enhanced recovery programs. Ultimately, identification of risk factors, and programmatic initiatives to drive down readmission will be important across surgical platforms, and the opportunity exists in patients with advanced stage ovarian cancer.
