Summary

Laparoscopic proximal gastrectomy using Kamikawa's hinged double flap method effectively treats upper third gastric cancer. This technique prevents reflux and allows endoscopic surveillance, showing excellent short-term patient outcomes.

Area of Science:

  • Surgical Oncology
  • Gastroenterology
  • Minimally Invasive Surgery

Background:

  • Establishing a standard proximal gastrectomy for upper third gastric cancer (UGC) remains challenging.
  • Current methods often fail to prevent gastro-esophageal reflux and hinder postoperative endoscopic surveillance.

Purpose of the Study:

  • To describe the laparoscopic proximal gastrectomy with the hinged double flap method (Kamikawa's method).
  • To evaluate the short- to medium-term outcomes of this surgical approach for UGC.

Main Methods:

  • 24 patients with early-stage primary UGC underwent laparoscopic proximal gastrectomy.
  • The technique involved preserving celiac and hepatic nerves, no pyloroplasty, and intracorporeal hand-sewn esophagogastric anastomosis.

Main Results:

  • No in-hospital deaths or conversions to open surgery.
  • Low complication rate (2/24 patients) with no reflux symptoms.
  • No cases of postoperative bowel obstruction or cancer recurrence observed.

Conclusions:

  • Laparoscopic proximal gastrectomy with Kamikawa's method is safe and effective for UGC.
  • The method excels in preventing gastro-esophageal reflux and facilitating endoscopic surveillance.
  • Further multi-center clinical studies are warranted to validate these findings.
