membranotomy can also be performed by advancing of a double-lumen catheter designed for sphincterotomy - Minitome double lumen sphincterotome (Cook Medical, USA) with a length of 200 cm—to the location of duodenal stenosis. After the device is activated, mixed current is supplied to it from the electrosurgical unit. Bleeding from the edges of the membrane can be stopped using a soft coagulation mode. After destruction of the membrane, the endoscope is advanced into the distal portion of the duodenum.

Postoperatively, patients are observed in the intensive and critical care unit until their respiratory and circulatory functions are stabilized. Enteral nutrition is initiated by the end of the first postoperative, as the lumen of the bowel was not opened. Diet advancement is based on tolerance to increasing amounts of nutrition, with gradual increase of nutrition volumes within the first two postoperative days.
