Introduction: Simultaneous organ resection is performed in 10% of laparoscopic gastrectomies for gastric cancer. The purpose of this study is to investigate the feasibility and safety of simultaneous organ resection.

Methods and Procedures: We retrospectively reviewed the medical records from a prospectively collected database of patients who underwent laparoscopic gastrectomy from May, 2003 to April, 2012 in a single center. The patients were classified into three groups: a gastrectomy only group as a control (no simultaneous resection or NS), a combined resection group (CB) characterized by additional resection due to tumor invasion and extensive lymphadenectomy, and a concomitant resection group (CC) including patients with other pathologic conditions. The clinical outcomes, in particular morbidity and mortality, were compared between the three groups.

Results: The NS, CB, and CC groups included 1883(90.1%), 66(3.2%), and 140(6.7%) patients, respectively. Mean operation time was longer in CB and CC patients than in NS patients (233.0±59.3, 227.4±100.9, and 180.1±54.0 min, respectively, p<0.001), and mean hospital stay was longer in the CB andCC group than in the NS group (9.6±5.2, 8.3±4.7, and 6.9±4.4, respectively,p<0.001). However, there were no statistically significant differences between the groups in the complication rate (p<0.141), complications more severe than grade II (p=0.066), or mortality (p=0.947).

Conclusions: Laparoscopic simultaneous organ resection during laparoscopic gastrectomy for gastric cancer prolonged the operation time and hospital stay but did not increase morbidity and mortality.
