STEP procedure
Also written as: STEP — Serial Transverse Enteroplasty
Surgical lengthening technique for short bowel syndrome that increases absorptive surface area.
Full Definition
Serial Transverse Enteroplasty is a surgical procedure designed to increase the functional length and surface area of the small intestine in patients with short bowel syndrome. The technique involves creating serial transverse divisions of the bowel wall while preserving the mesenteric blood supply, effectively lengthening the intestine in a zigzag fashion. This procedure can be performed multiple times and is particularly beneficial in pediatric patients who may outgrow their intestinal length. The goal is to enhance nutrient absorption and reduce dependence on parenteral nutrition.
Usage
Usage note: Always capitalize when used as an acronym; the full procedure name is rarely used in clinical practice.
