Intracorporeal Circular Stapled Esophagojejunostomy Using Conventional Purse-String Suture Instrument After Laparoscopic Total Gastrectomy

摘要

Background: An optimal alimentary tract reconstruction technique after laparoscopic total gastrectomy (LTG) remains controversial. The authors developed a new simple technique for intracorporeal esophagojejunal anastomosis that employs a conventional purse-string suture instrument (PSI) and circular stapler. Methods: From May 2014 to April 2016, 41 consecutive patients with gastric cancer underwent LTG in the author's institution. Intracorporeal esophagojejunal anastomosis using the following method was attempted for all patients. After total gastrectomy was completed laparoscopically, a small vertical incision (about 40mm) was created at the left midclavicular line and retracted by a wound retractor. An anvil of a 25mm circular stapler was introduced into the abdominal cavity. Then a previously prepared surgical glove, which was cut open at the thumb and the little finger through which the two hand shafts of the PSI were passed separately and sealed by ties, was attached to the wound retractor to maintain airtightness, and the PSI was introduced into the abdominal cavity. The following procedure was similar to conventional open surgery except that it was performed under laparoscopic vision. Results: Intracorporeal esophagojejunal anastomosis was performed successfully for all 41 patients. No case required extension of the initial incision for difficulties during anastomosis. The mean operation time was 245 minutes, and the mean time for the purse-string suture and anvil placement was 15 minutes. Tumor-free margins were achieved in all 41 patients. There were no anastomosis-related complications or other major surgical complications. Conclusions: With the described method, intracorporeal esophagojejunal anastomosis can be performed easily and safely.
