Anastomotic technique, gastrointestinal, end-to-end, open, continuous, hand suture, rotation technique - general and visceral surgery

As an example, the suture is demonstrated in a right-sided hemicolectomy. An ileotransversostomy is planned. Owing to the long mesenteries, the intestine can be rotated here; therefore, the anterior wall will be sutured first, and after rotating the intestine this will be followed by the posterior wall.

First, dissect free both intestinal walls at the planned anastomosis. Limit skeletonization of the intestinal wall to less than 1.5 cm for the small intestine and no more than 0.5-1 cm for the large bowel. Always check for a healthy, grayish-red color of the intestinal tissue, bleeding wound edges, and palpable or visible arterial pulses in the intestinal section to be sutured.

Block the intestine with intestinal clamps. By transecting the intestine with the scalpel perfusion of the intestinal wall will not be jeopardized.

Note: The ileum is resected at an oblique angle to account for the bigger lumen of the transverse colon; if necessary, extend the ileum length of the anastomosis by slitting the ileum along its antimesenteric aspect.
