Abstract

Background: Laparoscopic distal gastrectomy (LDG) is becoming the standard procedure for gastric cancer. However, supporting evidence thus far has been derived primarily from randomized control trials conducted by centers of excellence. In the present study we used the National Clinical Database (NCD) in Japan to prospectively accumulate data from diverse types of hospitals and examine whether LDG is a safe and valid standard procedure. Methods: From the NCD, 169 institutions were selected to form a cohort that was considered to be representative of Japan. From August 2014 to July 2015, 5288 patients who underwent LDG were registered prospectively, and clinical data were acquired through the NCD. To compare surgical outcomes between open distal gastrectomy (ODG) and LDG, we adjusted for confounding factors using propensity score matching, ultimately retrieving data from 1067 patients in each group. Results: There were no significant differences in the number of in-hospital deaths in the ODG and LDG groups (3/1067 vs. 6/1067; P = 0.51) or in the number of reoperations (20/1067 vs. 29/1067; P = 0.19). However, the length of hospital stay was significantly shorter in the LDG. Although wound infection and dehiscence were more common in the ODG group, LDG was more often associated with grade B or higher pancreatic fistulas. Conclusion: The safety and minimal invasiveness of LDG were confirmed in the present Japanese nationwide survey. However, care must be taken to prevent the formation of pancreatic fistulas with LDG, and further improvements in surgical quality are warranted in this regard.
