Description
Afferent Loop Syndrome (ALS) is a rare but important mechanical complication that can occur after Billroth II gastrectomy, Roux-en-Y reconstruction, pancreaticoduodenectomy (Whipple procedure), and other upper gastrointestinal surgeries. It develops when the afferent limb becomes partially or completely obstructed, leading to the accumulation of bile, pancreatic secretions, and intestinal fluids. If left untreated, it may result in bowel ischemia, perforation, cholangitis, or pancreatitis.
In this comprehensive educational lecture, Dr. R.K. Mishra explains the anatomy, pathophysiology, causes, clinical presentation, diagnosis, and management of Afferent Loop Syndrome. Learn how to recognize symptoms such as postprandial upper abdominal pain, nausea, bilious vomiting, abdominal distension, jaundice, and recurrent pancreatitis. The lecture also covers modern diagnostic tools including CT scan, upper GI contrast studies, endoscopy, and laboratory investigations, as well as the role of laparoscopic and endoscopic treatment.
This lecture is ideal for general surgeons, gastrointestinal surgeons, bariatric surgeons, gastroenterologists, residents, fellows, and healthcare professionals involved in upper GI surgery and postoperative patient care.
Topics Covered:
* What is Afferent Loop Syndrome?
* Relevant postoperative anatomy
* Causes and mechanisms of obstruction
* Acute and chronic clinical presentation
* Differential diagnosis
* CT scan, contrast studies, and endoscopic findings
* Medical stabilization and emergency management
* Endoscopic decompression techniques
* Laparoscopic and revisional surgical treatment
* Prevention and long-term outcomes
