A Modified Mucosal Incision for Easy Entry Into the Submucosal Space During Peroral Endoscopic Myotomy.

A technique of modified mucosal incision is discussed here for easy submucosal entry during peroral endoscopic myotomy (POEM). An L-shaped mucosal incision was used during peroral endoscopic myotomy in six cases of achalasia cardia. The incision was closed by clips in all the cases after the complete myotomy. Peroral endoscopic myotomy was successful in all six cases without any complication. The mucosal incision was closed by clips without any difficulty. The L-shaped mucosal incision for submucosal entry during peroral endoscopic myotomy made the procedure easy and quick.
