candy cane syndrome
A condition where the blind-ended afferent limb in gastric bypass becomes excessively long, causing food stasis and symptoms.
Full Definition
Candy cane syndrome is a mechanical complication that can occur after Roux-en-Y gastric bypass surgery when the afferent limb (the blind-ended portion of the divided duodenum) becomes elongated and creates a dependent loop resembling a candy cane shape. This configuration allows food particles and debris to collect in the blind limb, leading to symptoms such as epigastric pain, nausea, vomiting, and halitosis. The condition may require surgical revision to shorten the afferent limb and prevent food stasis.
Usage
Usage note: Descriptive term based on the radiographic appearance of the elongated limb.
