Gas in gallbladder-gallstone ileus?

Area of Science:

• Gastroenterology
• Abdominal Surgery
• Diagnostic Imaging

Background:

• Gallstone ileus is an infrequent cause of acute surgical abdomen.
• Non-specific symptoms frequently lead to delayed diagnosis of gallstone ileus.
• Small bowel obstruction (SBO) presentation requires careful diagnostic consideration.

Observation:

• The patient presented with a 2-day history of SBO.
• Initial plain abdominal radiography suggested SBO but was inconclusive for gallstone ileus.
• The patient had a history of gallstone disease and no prior abdominal surgeries.

Findings:

• Computed tomography (CT) of the abdomen is superior to plain radiography for diagnosing gallstone ileus.
• CT excels at detecting subtle findings like small amounts of gas and differentiating soft tissue densities.
• Early CT imaging is vital for accurate diagnosis and management of suspected gallstone ileus.

Implications:

• This case highlights the diagnostic limitations of plain radiography for gallstone ileus.
• Emphasizes the critical role of early CT scanning in patients with suspected gallstone ileus.
• Timely diagnosis through CT imaging can prevent delayed treatment and improve patient outcomes.
