[Laparoscopic resection of benign submucosal stomach tumors. A report of 65 cases]

Abstract

Aim of the study: The aim of this retrospective multicenter study was to evaluate the feasibility and the results of laparoscopic resection of benign submucosal gastric tumors.

Patients and methods: We reviewed the cases of 65 patients (20 centers) who have been operated on laparoscopically for benign submucosal gastric tumors. The tumor was symptomatic in 56 cases, located on the posterior wall in 23 cases. The mean size of the tumor was 3.8 cm (1.5-10).

Results: A laparoscopic wedge resection was performed in 53 cases. In 1 case a laparoscopic-assisted gastrectomy was done. A conversion to laparotomy was mandatory in 11 cases because of difficulties in localization of the tumor (n=5), in excision (n=5) or for safety reasons (n=1). There was no mortality. Two patients required reoperation because of bleeding. During follow-up, one patient developed recurrence requiring a second laparoscopic excision.

Conclusion: Most submucosal benign gastric tumors can be removed by laparoscopy. The location of the tumor (posterior wall or closed to the lesser curvature) or the size of the tumor (large or very small) can make the laparoscopic approach difficult.
