Objective: To evaluate the prevalence of low anterior resection syndrome (LARS) in patients with debulking surgery for primary advanced epithelial ovarian cancer and to identify potential risk factors for development of LARS.
Methods: We reviewed data on 552 consecutive patients with primary epithelial ovarian cancer (EOC), who underwent upfront or interval cytoreductive surgery including low anterior resection at two different academic institutions (Kliniken-Essen-Mitte, Germany, and Medical University of Vienna, Austria). Intestinal dysfunction was assessed by the validated LARS-questionnaire via telephone call. We performed descriptive statistics and a binary logistic regression model to evaluate risk factors for LARS.
Results: In total, 341 patients were eligible and 206 (60.4%) were successfully contacted and provided complete information. Major LARS was observed in 78 (37.9%) patients, minor LARS in 44 (21.4%) patients, and no LARS in 84 (40.8%) patients. The prevalence rate of major LARS was not influenced by time interval between surgery and LARS assessment, type of cytoreductive surgery, and recurrent disease at the time of assessment. In multivariate analyses, number of anastomosis was independently associated with an increased risk for presence of major LARS (OR 3.76 [1.95-7.24]). In the present cohort, 25.2% patients had more than one bowel anastomosis.
Conclusions: LARS in general and major LARS in particular seem to be a frequent long-term complication after debulking surgery including low anterior resection in primary advanced EOC patients. Particularly EOC patients with more than one bowel anastomosis during surgery seem to be at an increased risk for major LARS.
