We evaluated the feasibility of using this method for TLDG.
METHODS: A retrospective analysis was performed in 114 patients who underwent TLDG with DS anastomosis. Twenty-four patients reconstructed with a Roux-en-Y (RY) anastomosis during the same period were analyzed as control subjects.
RESULTS: The patient characteristics of DS and RY anastomoses were slightly different in terms of tumor location and extent of lymph node dissection, since this was not a prospective comparative study. Blood loss, postoperative complication rate and postoperative hospital stay were not different between the two groups. There was only 1 case of anastomotic leakage, and no case of anastomotic stricture after DS anastomosis. The length of the operation using DS anastomosis was significantly shorter than for RY anastomosis. The rates of body weight loss were not significantly different at 1 year after the operation.
CONCLUSIONS: Although this was a small retrospective analysis, DS anastomosis was feasible, required a shorter operation time, and had no associated complications. This method can therefore be recommended as a standard procedure for TLDG.
