Abstract

Background: Technological and operative advancements have allowed laparoscopic intragastric surgery (LIGS) to be applied in the treatment of superficial gastric or submucosal lesions. The aim of this study was to evaluate short- and long-term outcomes following LIGS.

Methods: From 2000 to 2013, 25 LIGSs were performed for superficial gastric lesions. Clinical records were reviewed retrospectively for peri-operative course and long-term outcomes with particular attention to the oncological follow-up for patients with malignant lesions.

Results: Nineteen (76%) lesions were located close to the EGJ, three (12%) in the lesser curvature, two (8%) in the posterior wall and one (4%) in the prepyloric-antral region. A multiport technique was used in 15 (60%) patients and a single-access approach in 10 (40%) patients. The median operative time was 140 (50-210) minutes. No conversion to open or conventional laparoscopic surgery was needed. Mortality was nil, and severe morbidity occurred in one (4%) patient. The median length of stay was 6 (3-10) days. Indications of LIGS were adenocarcinoma in 11 (44%) patients, gastrointestinal stromal tumors (GISTs) in 6 (24%) patients and benign lesions in eight (32%) patients. En bloc resection was obtained in 24 (96%) patients with R0 margins in 23 (92%) patients. After a median follow-up of 76 (26-171) months, recurrence was detected in 4 (36%) patients with advanced malignant adenocarcinoma.

Conclusion: LIGS provides an interesting alternative to major gastric and EGJ resection when endoscopic resection is not suitable for highly selected patients with superficial gastric lesions.
