Short-term outcomes after laparoscopic cytoreductive surgery in patients with limited peritoneal metastases from colorectal cancer.

Surgery 2018 November 20
BACKGROUND: The purpose of this study was to investigate the safety of laparoscopic cytoreductive surgery versus open surgery for patients with limited peritoneal metastases from colorectal cancer.

METHODS: Laparoscopic surgery for patients with colorectal cancer with peritoneal metastases has been performed at our institution since December 2004. We retrospectively evaluated data from patients with colorectal cancer metastatic to the peritoneum, with a peritoneal cancer index ≤10. We compared short-term operative and survival outcomes in the laparoscopic cytoreductive surgery group and open cytoreductive surgery group.

RESULTS: A total of 21 patients underwent open cytoreductive surgery and 42 underwent laparoscopic cytoreductive surgery, of whom 6 (14%) required open conversion. Clinicopathologic characteristics and operative outcomes were comparable between the groups. Complete cytoreduction was achieved in all patients in the laparoscopic cytoreductive surgery group and in 19 patients (91%) in the open cytoreductive surgery group (P = .042). Both the mean hospital stay and use of postoperative narcotics were significantly less in the laparoscopic cytoreductive surgery group than in the open cytoreductive surgery group. The type of operation (open cytoreductive surgery versus laparoscopic cytoreductive surgery) was not related to survival outcomes.

CONCLUSION: With careful selection by experienced laparoscopic surgeons, laparoscopic cytoreductive surgery was technically feasible and safe to treat colorectal cancer patients with limited peritoneal metastases.
