Afferent Loop Syndrome - an overview | ScienceDirect Topics
Afferent loop syndrome (ALS) after PDR is due to a partial or complete mechanical obstruction of bile, pancreatic juices, partially digested food, and in a redundant afferent jejunal limb. ALS is usually a late and chronic complication after PDR, and the higher-pressure fluid filled distal limb untwists and rapidly empties often into the ...
Afferent loop syndrome - Wikipedia
Afferent loop syndrome may result from volvulus, recurring cancer, stomal stenosis, adhesions, kinking at the anastomotic site, internal herniation, and gastrointestinal stones. [1] Laboratory investigations can help diagnose afferent loop syndrome, but imaging scans are required for a confirmation diagnosis. [2] .

Afferent limb syndrome (also called 'afferent loop syndrome') is a complication following Billroth II gastrojejunostomy characterized by acute or chronic intermittent obstruction of the afferent jejunal limb. Causes include jejunal herniation, intussusception, kinking, volvulus, marginal ulceration, para-anastomotic stenosis, and adhesion ...
