Laparoscopic total gastrectomy for remnant gastric cancer: feasibility study

Abstract

The benefits and feasibility of laparoscopic surgery for remnant gastric cancer are still unclear. The purpose of this study was to describe the detailed procedure and to evaluate the clinical short-term outcomes of laparoscopic total gastrectomy (LTG) compared with open total gastrectomy (OTG) for remnant gastric cancer (RGC). Of 1,247 consecutive patients who underwent gastrectomy for gastric cancer in our department at Kyushu University Hospital from January 1996 to May 2012, 22 patients who underwent successful curative resection of RGC with precise nodal dissection were enrolled in this study. Twelve patients underwent LTG and the remaining ten patients underwent OTG. We analyzed the clinical short-term outcomes of LTG and compared the results between LTG and OTG groups to evaluate the safety and feasibility of LTG. Twelve patients with RGC successfully underwent LTG without open conversion and morbidity. The mean operation time of LTG, 362.3 ± 68.4 min, was significantly longer than that of OTG (p = 0.0176), but the mean blood loss of LTG, 65.8 ± 62 g, was smaller than that of OTG (p < 0.01). The mean postoperative times to resumption of water and food intake were significantly shorter in the LTG group than in the OTG group (p < 0.01). The overall 3-year survival rate was comparable between the LTG and OTG groups (77.8 vs. 100 %; p = 0.9406). This study shows that LTG is a feasible and reliable procedure for the treatment of RGC in terms of short-term outcomes.
