Abstract:Objective To evaluate the feasibility, efficacy and safety of after initial peroral endoscopic myotomy (POEM) failure and repeated peroral endoscopic myotomy (Re-POEM) procedure for achalasia.Methods From February 2018 to August 2020, 10 patients with achalasia who failed after initial POEM and Re-POEM were performed in our center. The success rate, operation time, postoperative hospital length of stay, complications, total cost of hospitalization and follow-up were observed and statistically analyzed.Results Re-POEM procedures were conducted successfully in all the patients. Compared with the initial POEM, there were no statistically significant differences in operation time, postoperative fasting time, postoperative hospital length of stay and total cost of hospitalization. In terms of complications, there were no perforation, pleural effusion, gas-related complications in the two operations, and the incidence of mucosal injury, chest pain, fever, delayed bleeding were comparable (P > 0.05). After a median follow-up of 8.5 months (5~28 months), the Eckardt scores of all patients after Re-POEM were ≤ 3, with an average of 1.4 (1~3 Points). 3 patients developed clinically related gastroesophageal reflux disease (GERD), of which 1 case showed reflux esophagitis by gastroscopy.Conclusion Re-POEM is still safe and effective as a remedy for patients who underwent initial POEM for achalasia and presenting with either persistent or recurrent dysphagia.
