Clinical Application of Mucosal Valve Technique for Anastomosis During Esophagogastrostomy

Background The study aims to compare the efficacy in prevention of anastomotic complications using layer-to-layer mucosal valve technique versus circular stapled technique for esophagogastric intrathoracic anastomosis after resection for esophageal and gastric cardiac carcinoma. Methods From January 2005 to December 2010, 136 patients received layer-to-layer mucosal valve technique (LM group), 219 received circular stapled anastomosis (CS group) after curative intent resection for esophageal and gastric cardiac carcinoma. The technique details were reported and the clinical results were analyzed. Results The two groups were comparable on clinical baseline characteristics. The average duration of operation was longer with LM technique by 16 min, but without statistical significance ( P = 0.073). There was no anastomotic leakage in the LM group, while in the CS group, leakage occurred in seven patients (3.2 %, P = 0.047). Both the incidence and grade of postoperative dysphagia were significantly lower in the LM group ( P
