METHOD OF SURGICAL TREATMENT OF RECTAL TUMORS Russian patent published in 2019 - IPC A61B17/11 A61B17/03 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to surgery, and can be used in oncoprotrology in surgical treatment of rectal tumors. Anterior rectal resection is performed and a stump is formed by applying a linear mechanical suture. Head of stapling apparatus is introduced and fixed in adducting department of large intestine. Base portion of the suturing apparatus is introduced transanally into the lumen of the rectal stump. Suture of the stapling apparatus is drawn from a lumen of the rectal stump into a small pelvis cavity. Single U-suture is applied on the rectal stump at 1 cm to both sides of the stylet in a sagittal direction. For this purpose needle prick-in is performed on posterior surface of rectal stump at point at distance of at least 1 cm from linear mechanical suture. Needle is pricked out on a forward surface of a stump of a rectum in a point spaced at the distance of not less than 1 cm from a linear mechanical suture. Needle prick-in is performed on the rectal stump front surface, prick-out on its posterior surface. Base portion of the stapling apparatus is removed from the cavity of the rectum at a distance of not less than 2 cm. U-shaped suture is tightened around the stylet, bringing the edges of the linear mechanical seam closer to the inner diameter of the base portion of the stapling apparatus. U-shaped suture assembly is tied, the ligature ends are cut off. Base of the stapling apparatus is repeatedly inserted into the cavity of the rectal stump and connected to its head. Instrumental circular anastomosis is applied, after which the stapling apparatus is removed from the rectum.

EFFECT: method provides higher effectiveness of surgical treatment of rectal tumors, virtually ruling out inconsistencies of anastomosis and infection of a small pelvis cavity in the postoperative period due to U-shaped suture.
