ABSTRACT
Background:
Advanced achalasia cardia (AC) represents the end stage in the natural history of AC. Role of per oral endoscopic myotomy (POEM) in this technically difficult subset is emerging.
Methods:
Retrospective review of the patients who had undergone POEM for advanced AC with sigmoid esophagus. We assessed the technical success, clinical success and adverse event rate. Pre and post POEM Eckardt score (ES), integrated relaxation pressure-4sec (IRP-4), lower oesophageal sphincter pressure (LESP) and height and width of barium column at 5 minutes were noted.
Results:
Of the 85 patients who underwent POEM for AC, 10 patients had advanced AC with sigmoid esophagus of which eight were sigmoid and two were advanced sigmoid. The clinical and technical success was 100% with significant reduction of ES, IRP-4, LESP and height and width of barium column at 5 minutes. One patient had a minor adverse event in the form of mucosal injury that was closed with hemoclips. At a median follow up of 17 months there was no recurrence.
Conclusion:
Our study demonstrates POEM to be a safe and effective modality of treatment in this technically difficult subset of AC with sigmoid morphology.
