Efficacy and safety of peroral endoscopic myotomy in the treatment of achalasia cardia / 中南大学学报(医学版)

ABSTRACT

OBJECTIVE@#To evaluate the efficacy and safety of peroral endoscopic myotomy (POEM) for achalasia cardia (AC).
@*METHODS@#A total of 62 patients with AC were enrolled and treated with POEM in the Third Xiangya Hospital, Central South University from April 2012 to October 2014. The symptoms and complications were retrospectively analyzed.
@*RESULTS@#The ages of patients, including 32 males and 30 females, were 14-68 (43.2±5.6) years old. Eckardt scores were 4-6 or ≥7 for 25 patients or 37 patients (including 20 patients were at a score of 12). Thirteen patients suffered balloon expansion for 2-3 times. Sixty-one patients had completed POEM treatment, 1 patient were given Heller surgery instead of POEM because of extensive submucosal adhesion during POEM. The operative time for POEM was (60.8±15.1) min. Fourteen patients had mild subcutaneous emphysema. Among them, 5 suffered pneumoperitoneum and felt better after abdominal puncture exhaust; 2 patients suffered bronchospasm hypoxemia and were relieved after treatment by positive pressure oxygen for 1 h. The hospital stay was (4.3±1.2) d. The postoperative follow-up period was (11.4±5.4) months. Swallowing obstruction, vomiting and chest pain in patients was relieved at different degrees. The treatment effective rate was 100%. 
@*CONCLUSION@#POEM is a safe, effective and minimally invasive approach for AC.
