Can intraoperative endoscopy prevent esophagojejunal anastomotic leakage after total gastrectomy?

ABSTRACT

BACKGROUND: Esophagojejunostomy (EJ) is frequently performed after total gastrectomy for proximal gastric tumors. Despite evolving surgical techniques and improving perioperative care, the EJ leak is one of the most severe life-threatening complications. This study investigated the preventability of postoperative anastomotic complications by performing intraoperative endoscopy. METHODS: We included 86 patients who underwent total gastrectomy and Roux-en-Y esophagojejunostomy anastomosis in the study. Patients were divided into two groups and analyzed retrospectively. Group 1 consisted of 43 patients who did not undergo intraoperative endoscopy between 2017 and 2019, and Group 2 included 43 patients who underwent intraoperative endoscopy between 2019 and 2020. RESULTS: Esophagojejunostomy anastomotic leak (EAL) was observed in 2.3 % of patients in Group 1 but not in Group 2. Anastomosis-related abnormal findings (anastomotic defect, bleeding, air leak, mucosal separation) were recorded in seven patients of Group 2 during endoscopy. When such findings were observed, additional full-thickness sutures were placed on the anastomosis line and strengthened. Complication related to anastomosis was not observed in the postoperative period in Group 2. DISCUSSION: After a total gastrectomy, the most severe complication affecting mortality, morbidity, and consequently the cost of the disease is esophagojejunal anastomotic leakage. Most of these complications are induced by technical errors not noticed during surgery. The crucial advantage of performing intraoperative endoscopy is the technically detailed evaluation of anastomosis. CONCLUSION: Intraoperative endoscopy is a safe method to evaluate the strength of anastomosis. This procedure provides detailed information regarding anastomotic integrity.
