A second endoscope is inserted into the stomach through the created gastric fistula up to a lower boundary of the stricture. A guide string is delivered through the endoscope canal through a scar stricture. The string is taken with forceps and brought out through a mouth. A guide suture is fixed to the guide string. The suture is pulled through the gastric fistula. The suture is fixed to the skin within the restored gastric fistula and to a wing of nose.

EFFECT: method enables providing further forced minimally invasive non-surgical bougienage by the guide suture.
