Evaluation of short- und long-term morbidity of bowel mobilisation in patients with epithelial ovarian cancer after primary undergoing debulking surgery with special interest on Low anterior resection syndrome (LARS) - a retrospective analysis.

Interventions: Group 1: Evaluation of the LARS score in patients undergoing debulking surgery for ovarian cancer who underwent sigma / rectosigmoid or deep anterior rectal resection.
The control cohort will be:
1) Ovarian cancer patients who underwent debulking surgery without sigma/rectum resection;
2) breast cancer patients (matched-pair) who have neo / adjuvant chemotherapy based on their diagnosis but no history of abdominal/bowel surgery.
Primary outcome(s): The aim of the present study is to evaluate the prevalence of the low anterior resection syndrome (LARS) in patients with advanced epithelial ovarian cancer..
