primary anastomosis
Surgical connection of bowel segments performed at the initial operation without temporary diversion.
Full Definition
A surgical technique where intestinal continuity is restored immediately during the initial operation by directly connecting bowel segments, without creating a temporary stoma. In pediatric gastroenterology, primary anastomosis is often preferred when conditions allow, as it avoids the need for subsequent stoma closure procedures. The decision depends on factors such as bowel viability, absence of infection, adequate blood supply, and patient stability. Common applications include repair of intestinal atresias, treatment of necrotizing enterocolitis, and management of traumatic bowel injuries. Success rates are generally high when appropriate patient selection criteria are met, but complications may include anastomotic leak or stricture formation.
