Comparison of Laparoscopy-assisted Total Gastrectomy with Conventional Open Total Gastrectomy for Treating Early Proximal Gastric Cancer

Abstract

Purpose: The purpose of this study was to compare the short-term clinical outcomes of laparoscopy-assisted total gastrectomy (LATG) with conventional open total gastrectomy (OTG) for treating proximal early gastric cancer and to determine the usefulness of the LATG procedure. Methods: The records of 21 patients who underwent LATG for proximal early gastric cancer from January 2004 to August 2006 were retrospectively reviewed and compared with those records of 20 patients who underwent OTG during the same period. Results: The patient characteristics, including gender, age, body mass index and comorbidities, were similar between the two groups. Combined resections were more frequently done in the OTG group than in the LATG group. The blood loss in the LATG group was significantly less than that in the OTG group. The operating time, time to first flatus and initial oral intake and the postoperative hospital stay were significantly shorter in the LATG group. The number of resected lymph nodes, lymph node metastasis, histologic type, TNM stage, complications, leukocyte counts and serum lactic acid levels were not significantly different between the two groups. Conclusion: LATG is a technically safe and feasible procedure for treating proximal early gastric cancer. Prospective multi-center trials are necessary to establish LATG as the standard treatment for proximal early gastric cancer.
