Laparoscopic esophagogastrostomy using a knifeless linear stapler after proximal gastrectomy

Proximal gastrectomy should improve the late postoperative function in patients with gastric cancer located in the upper third of the stomach or esophagogastric junction. However, a standard method of esophagogastrostomy has not been established for improving the postoperative function. To prevent reflux and stenosis following proximal gastrectomy, we introduced a novel esophagogastrostomy method using a knifeless linear stapler. The stapler was inserted into holes created in both the esophagus and remnant stomach and fired proximally. A 1.5-cm incision was made from the edge of the entry hole between the staples. The entry hole was then closed with continuous sutures, and fundoplication was performed by wrapping the remnant stomach. We performed this technique in 12 consecutive patients without observing any anastomosis-related complications. The proportion of weight lost 1 year after surgery was 8.8%. Our surgical procedure might be feasible for treating gastric cancer located in the upper third of the stomach or esophagogastric junction.
