Risk Factors for Anatomic Leakage in Advanced Ovarian Cancer Surgery

Cytoreductive surgery is currently the main treatment for advanced epithelial ovarian cancer (AEOC), and the complete disease removal (RT=0) or the achievement of an optimal residual disease (RT \< 1 cm) remain the factors with the greatest prognostic impact, both in primary debulking surgery (PDS) and interval debulking surgery (IDS). To achieve the no residual disease (RT=0), several surgical manoeuvres are often needed both at the upper and lower abdomen, including intestinal resections. Recto-sigmoid resection is certainly the most frequent of intestinal resections, and it is also the one with the highest risk of complication. Albeit rare, anastomosis leakage (AL) is a life-threating condition and therefore it is the most feared of intestinal complications. The aim of this large single-center retrospective study was to assess the AL rate in patients subjected to colorectal resection and anastomosis during primary surgery (PDS or IDS) for advanced ovarian cancer, in a third referral centre for gynecologic oncology with ESGO certification. In addition, we evaluated several possible pre/intra and post-operative risk factors for AL in order to identify, at an early stage, the population at greatest risk, and attempt to reduce the morbidity and mortality of this severe post-operative complication
