Computed tomography (CT) reveals key signs of gallstone ileus, a rare intestinal obstruction. Early recognition of these CT findings can improve patient outcomes for this serious condition.

Area of Science:

  • Radiology
  • Gastroenterology
  • Surgical Pathology

Background:

  • Gallstone ileus is a rare but serious complication of gallstones.
  • It occurs when a gallstone erodes through the gallbladder wall and enters the gastrointestinal tract, causing obstruction.

Observation:

  • CT scans of three patients with gallstone ileus showed a distorted gallbladder with air and direct continuity to a thickened duodenal wall.
  • In one case, serial CT scans documented the progression from gallstone disease to cholecystitis and perforation into the duodenum.

Findings:

  • Gallstone ileus was diagnosed in all three patients via CT.
  • The CT findings included gallbladder distortion, intraluminal air, and small bowel gallstones.
  • One patient's CT progression showed evolution from gallstone disease to cholecystitis and duodenal perforation.

Implications:

  • Recognizing CT findings of gallstone ileus can lead to faster diagnosis and treatment.
  • Prompt intervention may reduce the high morbidity and mortality associated with gallstone ileus.
