Absence of port-site metastases following staging laparoscopy for gastric carcinoma Ausencia de metástasis en los orificios de trócares tras laparoscopia de estadificación en el carcinoma gástrico

Abstract

Background: port-site metastases (PSM) have been reported following oncological laparoscopic surgery. However, their frequency after laparoscopic examination in gastric cancer has not been well established. Material and methods: prospective follow-up of 41 patients having had a staging laparoscopy and a follow-up longer than 12 months. Mean age was 65 years (29-89). After staging, an open gastrectomy was performed in 33 cases. Mean follow-up was 21.4 (12-66) months. PSM was defined as a node in the former port-site wound with adenocarcinoma histology at biopsy. Results: no patient showed clinical signs of PSM or port-site recurrence, even in advanced stages. We had no morbidity or postoperative mortality attributable to laparoscopic manoeuvres, and no need for laparotomy in cases without a gastrectomy indication. Conclusions: our results suggest that staging laparoscopy is a safe procedure in gastric carcinoma, as it is not associated with PSM after even considerable follow-up, and has a very low complication rate.
