BackgroundAnastomotic leakage and stricture contribute to a large number of mortality and morbidity after esophagectomy. The aim of this work is to evaluate the outcome of modified double-layer hand-sewn esophagogastric anastomosis during minimally invasive esophagectomy for esophageal cancer.MethodsThe clinicopathological data of 176 consecutive esophageal cancer patients who underwent cervical esophagogastric anastomosis using modified double-layer hand-sewn technique after radical esophagectomy were retrospectively reviewed. Total minimally invasive approach, including thoracoscopic surgery for thoracic procedure and laparoscopic approach for abdominal procedure, was implemented during the radical Mckeown esophagectomy. Patients were followed up for the assessment of postoperative anastomotic complications including anastomotic leakage and stricture, being the primary outcome measures for this study.ResultsAnastomotic leakage occurred in 2 of 176 patients (1.1%); both of the patients experienced only minor leakage and were treated conservatively. There was no significant difference in leakage between patients with and without major comorbidity (p = 0.331). After a mean follow-up of 21.3 months, four patients (4/176, 2.3%) developed benign anastomotic strictures, including those 2 patients experienced postoperative leakage. Symptoms for stricture were improved by endoscopic dilatations in all 4 patients. Besides, there was one case (1/176, 0.6%) of gastric necrosis in this cohort, who was also successfully managed by conservative therapy with no operative mortality.ConclusionThis modified double-layer hand-sewn anastomosis is a highly safe and stable technique for esophagogastrostomy, which is an effective way to prevent both anastomotic leakage and stricture.
