Intestinal Lengthening Procedure
Surgical techniques to increase functional bowel length in patients with short gut syndrome, including STEP and spiral lengthening.
Full Definition
Intestinal lengthening procedures are surgical techniques designed to increase the functional length and absorptive capacity of the small intestine in patients with short gut syndrome. The Serial Transverse Enteroplasty Procedure (STEP) involves creating a zigzag pattern of stapled divisions to lengthen the bowel while narrowing the diameter. Spiral intestinal lengthening involves creating a helical division pattern. These procedures aim to improve nutritional independence and reduce dependence on total parenteral nutrition. Success rates vary, and patients may require multiple procedures or eventual intestinal transplantation.
Usage
Usage note: Always specify the type of lengthening procedure (STEP, spiral, or Bianchi) performed.
