Laparoscopic versus open total gastrectomy for advanced proximal gastric carcinoma: a matched pair analysis

Laparoscopic total gastrectomy for advanced proximal gastric carcinoma is a complex and challenging procedure, limited to a few expert centers. This study analyzed the short- and long-term outcomes of laparoscopic total gastrectomy for advanced proximal gastric carcinoma compared with open gastrectomy. From January 2008 to January 2015, 61 patients underwent laparoscopic total gastrectomy for advanced proximal gastric carcinoma. They were matched and compared to 61 patients who underwent a conventional open operation. Short-term operative and postoperative outcomes as well as long-term outcomes, including overall survival and disease-free survival rates, were assessed. Patients were well matched for several preoperative factors. Overall postoperative 30-day complication rates were significantly higher for the open group. No significant difference was seen in 5-year overall survival and 5-year disease-free survival between the open and laparoscopic groups. The same result was seen in subgroup analyses of TNM stage. This study shows the feasibility of laparoscopic total gastrectomy for advanced proximal gastric carcinoma compared to open resection in regard to both short- and long-term outcomes. Laparoscopic surgery offers many advantages commonly attributed to laparoscopy and is well suited for proximal gastric carcinoma when performed by experienced surgeons.
