Laparoscopy-Assisted Proximal Gastrectomy with the Hinged Double Flap Method

Abstract

Background

No standard proximal gastrectomy method for gastric cancer of the upper third of the stomach (UGC) has been established because few of the current methods prevent gastro-esophageal reflux and allow easy postoperative endoscopic surveillance. In the present study, we describe laparoscopic proximal gastrectomy with the hinged double flap method (Kamikawa's method) in detail and examine the short- to medium-term outcomes of this approach, which resulted in excellent postoperative function.

Methods

Between 2011 and 2015, 24 patients with early-stage primary UGC underwent laparoscopic proximal gastrectomy with the above-mentioned method. The celiac and hepatic nerves were preserved without pyloroplasty. A hand-sewn esophagogastric anastomosis was produced intracorporeally.

Results

There were no in-hospital deaths, and none of the patients were converted to open surgery. Complications occurred in two patients in the early part of this study (minor anastomotic leakage in one case and an abdominal abscess in the other). None of the patients exhibited symptoms of reflux. Regarding the patients' postoperative endoscopic classifications, 17, 2, and 1 patient were considered to have grade N or M, grade A, and grade B esophagitis, respectively. All of the patients remain alive, and no cases of postoperative bowel obstruction or recurrent cancer have been observed.

Conclusions

This method can be performed safely and achieves excellent outcomes in terms of preventing gastro-esophageal reflux. It deserves further evaluation in a multi-center clinical study.
