[Critical areas and suture incompetence in interintestinal anastomoses]
Insights
Disrupting the right colon's blood supply can harm the small intestine. Surgeons must position sutures carefully during intestinal resections to maintain blood flow and ensure tissue viability.
Area of Science:
- Gastroenterology and Surgical Anatomy
Background:
- The intestine has critical zones in its blood supply that are vital for maintaining tissue health.
- Understanding these vascular territories is crucial for preventing complications during gastrointestinal surgery.
Abstract:
Clinical observations confirming the presence of critical zones in blood supply of the intestine are presented. It was shown that exclusion of the vessels of the right half of the colon is responsible for the disturbance of blood supply in the terminal part of the small intestine. Suture bands should be displaced to the level at which the intramural pressure ensures the viability of the intestine in the anastomosis zone. This should be taken into account in resections of the transverse colon, left-side hemicolectomy, abdominal resection and frontal resection of the rectum.
