Objective: Splenectomy with or without distal pancreatectomy is occasionally performed during cytoreductive surgery for advanced ovarian cancer. We investigated pre-, intra-, postoperative risk factors and predictors of clinically relevant postoperative pancreatic fistula (CR-POPF) in patients who underwent cytoreductive surgery for advanced ovarian cancer.
Methods: We investigated 165 consecutive patients with ovarian, fallopian tube, and peritoneal carcinoma categorized as stage III/IV disease, who underwent splenectomy with or without distal pancreatectomy as a component of cytoreductive surgery performed as initial treatment at Chiba University Hospital. Patient characteristics, clinical factors, and surgical outcomes were compared between those with and without CR-POPF.
Results: CR-POPF occurred in 20 patients (12%). There were no significant intergroup differences in the characteristics between patients with CR-POPF and patients without CR-POPF except for operative time, intraoperative blood loss, amylase (AMY) levels in drain fluid on postoperative day (POD)1 and POD3, and pancreatic stump thickness. Multivariate analysis showed that the POD3 drain fluid AMY level was the only significant risk factor and predictor of CR-POPF in patients who underwent cytoreductive surgery for advanced ovarian cancer. The receiver operating characteristic curve of the POD3 drain fluid AMY level, which predicted development of CR-POPF showed an area under the curve of 0.77, and the optimal cut-off value of AMY was 808 U/L. A pancreatic fistula did not occur in patients with POD3 drain fluid AMY levels <130 U/L.
Conclusion: The POD3 drain fluid AMY level can be early diagnostic predictor CR-POPF after splenectomy with or without distal pancreatectomy for advanced ovarian cancer.
