Background And Study Aims:
In order to perform peroral endoscopic myotomy (POEM) safely, retained liquid and food debris must be removed before the procedure is started. We developed a novel technique using a super-slim gastroscope, and a gastric tube to remove retained food debris in achalasia patients. In this study, the safety and efficacy of this novel technique were investigated.
Patients And Methods:
Eleven patients with achalasia were enrolled in this study and underwent this novel method for esophageal clearance.
Results:
All patients had complete clearance of the retained food debris using this method. The median procedure time (range) was 13 (6 - 30) minutes. There were no serious adverse events (AEs) and one minor AE of mucosal erythema due to mucosal suctioning.
Conclusion:
This novel method for esophageal clearance is safe and effective in achalasia patients with large amounts of retained food debris.
