METHOD FOR FORMING A SINGLE-ROW INTERINTESTINAL ANASTOMOSIS Russian patent published in 2020 - IPC A61B17/00 A61B17/11 

FIELD: medicine; abdominal surgery.

SUBSTANCE: point of intersection of intestine segments is taken on direct Kocher's clamps for 2–3 minutes, intestine is leveled with a clamp. After the clamp is removed, the squeezed edges are coagulated without opening the stuck together lumen. Anastomosed segments of the intestine are sutured together by two ligatures at distance of 1 cm from the edge. Posterior lip of the anastomosis is formed with a single-row continuous suture without mucosal capture, grasping 5–7 mm from the edge, and at pitch of 5–7 mm, a submucosal-muscular-serous and seromuscular-submucosal layer is sutured. In the transition to the anterior lip of the anastomosis, a fixing suture is applied—perpendicular to the axis of the anastomosis from the inside to the outside, a pricked out and pricked out on one of the intestinal segments, then suture is applied on both pieces of the intestine in parallel to the anastomosis axis. Then a prick-in and out-of-the-inside inside perpendicular to an anastomosis axis on another intestine segment, after that the lumen of both intestine sections is opened. Anterior lip of anastomosis is also formed continuously without a mucosa. When the anterior anastomosis lip is completed, the continuous suture is continued at 5–7 mm beyond the beginning of the anastomosis with the serous-muscular layer capture without engorgement of the intestinal mucosa.

EFFECT: method provides creation of single-row intestinal interstitial anastomosis with minimally narrowed lumen, reduced risk of developing stricture and inconsistency of anastomosis.
