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., (Copyright © 2020 Elsevier Masson SAS.

Background: The majority of laparoscopic gastrectomy (LG) reports arise from Asia and the benefit of this approach in western countries remains unclear. The objective of this study was to compare the postoperative outcomes between LG and open gastrectomy (OG) for gastric cancer in a western center., Methods: Between 2005 and 2015, all consecutive patients with gastric cancer who underwent either LG or OG were enrolled. Postoperative morbimortality was evaluated according to Dindo-Clavien classification., Results: Over 164 patients, 60 had LG and 104 OG with a mean age of 62 and 65 years, respectively. Total gastrectomy represented 58% of LG and 54% of OG (P=0.749). Operative time was not different in the two groups (160.8 vs. 174.2min, P=0.780) so as intraoperative blood loss (111 vs. 173mL, P=0.057). The rate of severe complications (including postoperative bleeding) was significantly higher in the LG group (40% vs. 23%, P=0.012) so as reoperation rate (27% vs. 6%, P<0.001). There was no statistical difference in terms of postoperative mortality (0 vs. 3%, P=0.252) or length of hospital stay (20 vs. 16 days, P=0.116)., Conclusion: Laparoscopic gastrectomy for the treatment of gastric cancer in western countries appears to be feasible but with a higher rate of severe complications compared to open gastrectomy., (Copyright © 2017 Elsevier Masson SAS.
