Background: For laparoscopic gastrectomy, it is significant to reduce the incidence of anastomotic leakage. The authors develop a novel technique for safe extracorporeal anastomosis that employs the bronchus forceps to reinforce the esophageal ring. @@@ Methods: From January 2017 to July 2020, 173 consecutive patients with gastric cancer received laparoscopic total gastrectomy or laparoscopic proximal gastrectomy. One hundred thirty-one patients only underwent extracorporeal anastomosis with a purse-string suture instrument (PSI) and a 25 mm circular stapler (Ethicon Intraluminal Circular Staplers CDH25A, Ethicon) (Conventional Surgery Group). In addition to these tools for extracorporeal anastomosis, the surgeon creatively used bronchus forceps to reinforce the esophageal ring on the anvil of circular stapler in 42 patients (Bronchus Forceps Ligation Group). The condition and the mean diameter of the narrowest part of the esophageal rings, postoperative outcomes, and complications were compared between the two groups. @@@ Results: Under direct vision, the esophageal rings were more complete in the Bronchus Forceps Ligation Group. Furthermore, the mean diameter of the narrowest part of the esophageal rings in the Bronchus Forceps Ligation Group was wider than that in the Conventional Surgery Group (4.34 +/- 0.84 versus 2.68 +/- 0.74 mm; P < .001). Meanwhile, the incidence of anastomotic leakage was lower in the Bronchus Forceps Ligation Group. Although reinforcing the anvil with the bronchus forceps will add additional surgery time, almost all can be done in less than 5 minutes. @@@ Conclusions: With applying the bronchus forceps to reinforce the esophageal ring on the anvil of the circular stapler, the extracorporeal anastomosis can be performed more safely.
