A Rare Case of Afferent Loop Syndrome

Afferent loop syndrome (ALS) is an uncommon mechanical complication defined by a distal obstruction causing distension of the afferent limb secondary to the accumulation of bile, pancreatic fluid, and proximal small bowel secretions, occurring after procedures involving anastomosis of stomach or esophagus to jejunum. It was described with Billroth II gastrojejunostomy and other Roux-en-y procedures.
