Summary
Congenital absence of gallbladder (CAGB) often presents with biliary symptoms and is difficult to diagnose with standard imaging. Abdominal CT is crucial for accurate CAGB diagnosis, preventing unnecessary surgical exploration.
Area of Science:
- Gastroenterology
- Diagnostic Imaging
- Surgical Pathology
Background:
- Congenital absence of gallbladder (CAGB) is a rare condition.
- Patients with CAGB frequently present with various biliary symptoms.
- Preoperative diagnostic challenges are common in identifying CAGB.
Purpose of the Study:
- To review surgically confirmed cases of CAGB.
- To evaluate the diagnostic efficacy of various imaging modalities for CAGB.
- To highlight the importance of appropriate diagnostic work-up in suspected CAGB cases.
Main Methods:
- Retrospective review of nine surgically proven CAGB cases.
- Analysis of diagnostic performance of abdominal ultrasonography, cholecystography, and endoscopic retrograde cholangiography.
- Evaluation of abdominal computed tomography (CT) in one case.
- Confirmation of CAGB through surgical exploration and operative cholangiography.
Main Results:
- Standard biliary imaging tests failed to diagnose CAGB and often suggested other conditions.
- Abdominal CT was the only imaging modality that accurately identified CAGB in the reviewed cases.
- Five patients had concurrent biliary pathologies, while four had isolated CAGB.
- Surgical exploration confirmed CAGB in all nine patients.
Conclusions:
- CAGB is a rare but significant clinical entity.
- Accurate diagnosis of CAGB is challenging with conventional imaging.
- Abdominal CT should be considered in the diagnostic work-up for suspected CAGB.
- Appropriate imaging can prevent unnecessary surgical interventions, especially in isolated CAGB cases.
