Comparing intracorporeal mechanical anastomosis vs. hand-sewn esophagojejunostomy after total laparoscopic gastrectomy for esophagogastric junction cancer: a single-center study.

Objective: This study aimed to compare the effects of continuous hand-sewn esophagojejunostomy with barbed suture and mechanical anastomosis in total laparoscopic gastrectomy for esophagogastric junction cancer.

Materials And Methods: The clinical data of 60 patients who underwent total laparoscopic total gastrectomy from January 2020 to October 2021 were collected retrospectively. Baseline data and short-term surgical results of patients in the hand-sewn anastomosis (n = 30) and mechanical anastomosis (n = 30) groups were analyzed.

Results: No significant differences were detected in the baseline data between groups. Meanwhile, the hand-sewn group had a shorter anastomosis time (21.2 ± 4.9 min vs. 27.9 ± 6.9 min, p < 0.001) and a decreased operation cost (CNY 70608.3 ± 8106.7 vs. CNY 76485.6 ± 3149.9, p = 0.001). The tumor margin distance in the hand-sewn group was longer than in the mechanical group (2.7 ± 0.4 cm vs. 2.2 ± 0.75 cm, p = 0.002). In esophagojejunostomy anastomosis, the distance between the jejunal opening and jejunal stump in the hand-sewn group was significantly shorter than that in the mechanical group (2.2 ± 0.54 cm vs. 5.7 ± 0.6 cm, p < 0.001). No significant difference was detected in the incidence of postoperative anastomotic complications.

Conclusion: The continuous hand-sewn anastomosis with barbed suture in total laparoscopic gastrectomy for esophagogastric junction cancer is practical, safe, and cost-effective. It is also an effective supplementary technique for mechanical anastomosis.
