Abstract

Achalasia is characterized by the absence of lower esophageal sphincter relaxation and esophageal aperistalsis. Diagnosis is confirmed through high-resolution esophageal manometry. Laparoscopic myotomy is the standard treatment, but peroral endoscopic myotomy (POEM) is a safe and effective alternative, with good short-term and medium-term results. Our aim was to describe the short-term and medium-term experience with POEM at a tertiary care center. The study was conducted within the time frame of November 2014 and February 2017. Treatment-naïve achalasia patients and previously-treated achalasia patients that were candidates for POEM were included. A protocolized 24-month follow-up was carried out. Fifty procedures were included and 31 (68%) were performed on women. Forty-one (82%) of the procedures were carried out on previously untreated patients, 7 (14%) were performed on previously treated patients, and 2 (4%) of the patients had redo-POEM. The mean age of the patients was 48.8±14.1 years. The pre-POEM Eckardt score was 9 and the integrated relaxation pressure was 24.4mmHg. Sixty-eight percent of the patients had type ii achalasia. Procedure time was 80min and myotomy length was 12.6cm. Hospital stay was 3 days and subcutan...Continue Reading
