Bowel hath no fury like a gallbladder inflamed.

Gallstone ileus is a well-established phenomenon in which a large gallstone leads to mechanical small bowel obstruction. This case, however, reports the novel finding of a patient presenting with suprapubic pain and guarding caused by paralytic ileus of the small bowel and a duodenal perforation secondary to a necrotic gallbladder. It highlights the importance of distinguishing between gallstone ileus and paralytic ileus and how the management of the two conditions differs. Furthermore, this article discusses how paralytic ileus caused by intra-abdominal inflammatory conditions such as cholecystitis can mask the typical clinical findings making the diagnosis difficult.
