RESUMO
INTRODUCTION: In ovarian cancer (OC), survival benefit in case of complete cytoreduction with absence of residual tumor has been clearly demonstrated; however, it often requires extensive surgery. Particularly, pancreatic resection during cytoreduction, may severely impact perioperative morbidity and mortality. OBJECTIVES: The aim of this systematic review is to evaluate complication rates and related optimal management of ovarian cancer patients undergoing pancreatic resection as part of cytoreductive surgery. METHODS: Literature was searched for relevant records reporting distal pancreatectomy for advanced ovarian cancer. All cohorts were rated for quality. We focused our analysis on complications related to pancreatic surgical procedures evaluating the following outcomes: pancreatic fistula (PF), abdominal abscess, pancreatitis, iatrogenic diabetes, hemorrhage from splenic vessels and pancreatic-surgery-related mortality. RESULTS: The most frequent complication reported was PF. Similar rates of PF were reported after hand-sewn (20%) or stapled closure (24%). Continued drainage is the standard treatment, and often, the leak can be managed conservatively and does not require re-intervention. Abdominal abscess is the second most frequent complication and generally follows a non-adequately drained PF and often required re-laparotomy. Pancreatitis is a rare event that could be treated conservatively; however, death can occur in case of necrotic evolution. Cases of post-operative hemorrhage due to splenic vessel bleeding have been described and represent an emergency. CONCLUSIONS: Knowledge of pancreatic surgery and management of possible complications ought to be present in the oncologic-gynecologic armamentarium. All patients should be referred to specialized, dedicated, tertiary centers in order to reduce, promptly recognize and optimally manage complications.
