Abstract
Peroral endoscopic myotomy (POEM) for treatment of esophageal motility disorders has recently been reported to be highly effective and less invasive than other treatment. POEM was recently introduced in Okayama University Hospital under the supervision of a physician from a high-volume center. To verify the safety and efficacy of POEM during its introduction in our institution. We examined 10 cases in whom POEM was performed between January 2016 and April 2017. The patients included 7 men and 3 women, with a median age (range) of 49 years (17-74) and median symptom duration of 6 years (1-21). Seven patients had a straight esophagus, and the remaining 3 had a sigmoid esophagus. According to the Chicago classification, 6 patients were diagnosed with type I achalasia, 2 with type II achalasia, and 2 with distal esophagus spasm. Treatment outcomes and adverse events were evaluated. Treatment success was defined as a > 3 decrease in Eckardt score or a score of <3 at the time of discharge. The treatment success rate was 90%, with the average Eckardt score decreasing significantly, from 4.7 to 0.9 (p<0.05). No mucosal perforation, severe infection, mediastinitis, severe bleeding, or gastroesophageal reflux occurred intraoperatively or postoperatively. POEM was introduced to Okayama University Hospital, and the first 10 cases were accomplished safely and effectively under the supervision of an expert physician from a high-volume center.
