Abstract

BACKGROUND/AIMS
The risk of peritoneal seeding following perforation after endoscopic resection in patients with early gastric cancer is unclear. The purpose of this study was to investigate long-term clinical outcomes including peritoneal seeding and overall survival rate following gastric perforation during endoscopic submucosal dissection (ESD).
METHODS
Between January 2002 and March 2015, 556 patients were diagnosed with early gastric cancer and underwent ESD. Among them, 34 patients (6.1%) experienced gastric perforation during ESD. Clinicopathological data of these patients were reviewed to determine the clinical outcome and evidence of peritoneal seeding.
RESULTS
Among 34 patients with perforation, macroperforations occurred during ESD in 17 cases (50%), and microperforation was identified in the remaining 17 cases (50%). All patients except one who underwent emergency surgery due to severe panperitonitis were managed successfully by endoscopic clipping (n=27) or conservative medical treatment (n=6). No evidence of peritoneal seeding after perforation associated with ESD was found in our cohort. Cumulative survival rates did not differ between the perforation and non-perforation groups (p=0.691). Furthermore, mortality was not associated with perforation. In addition, multivariate analysis showed that tumor size and achievement of curative resection were related to cancer recurrence. Perforation was not associated with cancer recurrence and survival.
CONCLUSIONS
Perforation associated with ESD does not lead to worse clinical outcomes such as peritoneal seeding or cumulative survival rate. Therefore, periodic follow-up might be possible if curative resection was achieved even if perforation occurred during ESD.
