Insights
Duplicated gallbladder (GB) is a rare congenital anomaly requiring careful surgical planning. This case highlights the importance of preoperative evaluation for concurrent biliary anomalies to ensure patient safety during surgery.
Area of Science:
- Gastroenterology
- Surgical Anatomy
- Congenital Anomalies
Background:
- Duplicated gallbladder (GB) is a rare congenital anomaly.
- Surgical management requires careful consideration due to potential concurrent biliary duct anomalies and risks to adjacent arteries.
Observation:
- An 80-year-old male presented with right upper quadrant abdominal pain.
- Computed tomography revealed cholecystitis with a two-bodied GB.
- Magnetic resonance choledochopancreatography identified a V-shaped duplicated GB with a common cystic duct and noted the right posterior hepatic duct joining the common bile duct (CBD) near the cystic duct.
Findings:
- The patient underwent successful laparoscopic cholecystectomy.
- No adjacent organ injury occurred during the procedure.
- The patient was discharged uneventfully.
Implications:
- Preoperative evaluation is crucial for patients with suspected duplicated GB.
- Careful surgical planning and selection of adequate procedures are essential to mitigate risks associated with concurrent biliary anomalies.
- This case underscores the importance of detailed anatomical assessment in managing rare congenital GB variations.
Abstract:
Duplicated gallbladder (GB) is a rare congenital disease. Surgical management of a duplicated GB needs special care because of concurrent bile duct anomalies and the risk of injuring adjacent arteries during surgery. An 80-year-old man visited an emergency room with right upper quadrant abdominal pain. Computed tomography (CT) revealed cholecystitis with a 2-bodied GB. Because of this unusual finding, magnetic resonance choledochopancreatography was performed to detect possible biliary anomalies. The 2 GB bodies were unified at the neck with a common cystic duct, a so-called V-shaped duplicated GB. The patient's right posterior hepatic duct joined the common bile duct (CBD) near the cystic duct. The patient underwent laparoscopic cholecystectomy without adjacent organ injury, and was discharged uneventfully. Surgeons should carefully evaluate the patient preoperatively and select adequate surgical procedures in patients with suspected duplicated GB because of the risk of concurrent biliary anomalies.
