Laparoscopically assisted total gastrectomy with lymph node dissection for upper and middle gastric cancer

Abstract

Background: In recent years, laparoscopic gastrectomy has been applied for the treatment of gastric cancer in Japan and Western countries. This report describes the short- and long-term results for patients with gastric cancer who underwent laparoscopically assisted total gastrectomy (LATG) with lymph node dissection.

Methods: From September 1999 to December 2007, 20 patients underwent LATG, and 18 underwent conventional open total gastrectomy (OTG) for upper and middle gastric cancer. The indications for LATG included depth of tumor invasion limited to the mucosa or submucosa and absence of lymph node metastases in preoperative examinations. The LATG and OTG procedures for gastric cancer were compared in terms of pathologic findings, operative outcome, complications, and survival.

Results: No significant difference was found between LATG and OTG in terms of operation time (254 vs 248 min.), number of lymph nodes (26 vs 35), complication rate (25% vs 17%), or 5-year cumulative survival rate (95% vs 90.9%). Differences between LATG and OTG were found with regard to blood loss (299 vs 758 g) and postoperative hospitalization (19 vs 29 days).

Conclusion: For properly selected patients, laparoscopically assisted total gastrectomy can be a curative and minimally invasive treatment for early gastric cancer.
