Objective: To evaluate the technical feasibility, effectiveness, and safety of robot-assisted gastrectomy (RAG) with lymphadenectomy, using the da Vinci system through analyses of our initial series of 100 consecutive patients. SUMMARY BACKGROUND DATA:: The application of robotic surgery was proven to be one of the best cutting-edge technologies for successful minimally invasive surgery by providing solutions to the many drawbacks of laparoscopic surgery, yet few reports have studied robotic surgery in gastric cancer. METHODS:: A review of a prospectively designed database at our institute from July 2005 to October 2007 revealed a series of 100 consecutive RAG patients with a preoperative diagnosis of early gastric cancer. Clinicopathologic characteristics and surgical outcomes were analyzed. RESULTS:: All operations were performed successfully without open or laparoscopic conversion. There were 33 total gastrectomies and 67 subtotal gastrectomies with D1+β or extended lymphadenectomy (D2). The mean total operation time and console time were 231 and 150 minutes, respectively. There were 13 postoperative morbidities and 1 postoperative mortality. The first flatus was noted on postoperative day 2.9, soft diet was started on postoperative day 4.2, and the mean postoperative hospital stay was 7.8 days. Although all patients were diagnosed as early gastric cancer preoperatively, the final pathology report revealed that 19 patients exhibited a depth deeper than T2. The mean number of retrieved lymph nodes was 36.7 (range, 11-83). None of the specimens showed microscopic tumor involvement in the resection line. CONCLUSIONS:: This study demonstrated that RAG with lymphadenectomy can be applied safely and effectively for patients with gastric cancer.
