METHOD FOR GASTROENTEROANASTOMOSIS FORMATION Russian patent published in 2014 - IPC A61B17/00 A61B17/11 

FIELD: medicine.

SUBSTANCE: Billroth-II operation is performed. A window is created in the transverse mesocolon; an initial jejunem is delivered through the above window into an upper level of the abdominal cavity. A gastroenteroanastomosis is formed with the use of an adductor loop of no more than 3.5-4.5 cm from the duodenojejuneal junction. The intestinal loop is anchored with three seromuscular interrupted sutures in the transverse direction to a posterior wall of the stomach along the greater curvature isoperistaltically at 2.0-2.5 cm from the gastroenteroanastomosis line. The gastric stump is positioned horizontally by high fixation of the latter in the mesocolon window with interrupted sutures. The gastroenteroanastomosis is transferred into the medium abdominal wall and directed with its lumen to the right and upward at an angle of about 30° to a sagittal line.

EFFECT: method enables avoiding postoperative complications and leakage by forming a transversal gastroenteroanastomosis, which represents a valvular anastomosis arranged at the level of the gastric bottom and a lumen of which is deflected to the left and upwards from the sagittal line, and using the ultra-short adductor loop.
