Abstract

Introduction: The most common intrathoracic anastomosis techniques for Siewert type II adenocarcinoma of the esophagogastric junction (AEG) are the overlap and transorally inserted anvil (OrVil) methods. However, the criteria for choosing between these two methods require further study.

Aim: This retrospective study aimed to compare the efficacy and safety of overlap versus OrVil anastomosis in transabdominal radical surgery for Siewert type II adenocarcinoma of the esophagogastric junction.

Material and methods: A total of 34 patients with Siewert type II AEG who underwent transabdominal radical surgery and intrathoracic anastomosis with the overlap or OrVil methods at our center from January 2018 to June 2019 were retrospectively analyzed. The relevant surgical and postoperative complication data of the two groups were collected and analyzed.

Results: Clinical characteristics: the mean tumor size was 7.5 ±2.4 cm in the OrVil group and 4.3 ±1.9 cm in the overlap group (p < 0.05). Surgery: the distance from the upper resection margin of the esophagus to the tumor was 3.2 ±0.84 cm in the OrVil group and 2.4 ±0.6 cm in the overlap group (p < 0.05). Postoperative complications: there were two cases of pleural effusion in the OrVil group and 18 cases of pleural effusion in the overlap group (p < 0.05).

Conclusions: There is no significant difference between the OrVil and overlap anastomosis in terms of the feasibility and safety; however, OrVil anastomosis can provide a higher margin of resection of the esophagus and is suitable for tumors with extensive esophageal invasion.

Keywords: OrVil anastomosis; adenocarcinoma of the esophagogastric junction; esophagojejunostomy; overlap anastomosis; surgical complications.
