The patient underwent staged surgical and endoscopic management: early cholecystectomy for acute cholecystitis followed by post-operative endoscopic retrograde cholangiopancreatography (ERCP) with therapeutic sphincterotomy for CBD obstruction from periampullary diverticulum compression.

The patient underwent staged surgical and endoscopic management: early cholecystectomy for acute cholecystitis followed by post-operative endoscopic retrograde cholangiopancreatography (ERCP) with therapeutic sphincterotomy for CBD obstruction from periampullary diverticulum compression. This case illustrates the diagnostic challenges in identifying Lemmel syndrome when acute cholecystitis masks the underlying obstructive process, and demonstrates a practical staged approach to managing concurrent biliary pathology.
