High insertion of cystic duct at the gallbladder fundus: An undescribed anomaly!

Area of Science:

• Surgical Anatomy
• Gastroenterology
• Medical Case Reports

Background:

• Biliary tree anatomy exhibits significant variations in up to 30% of the population.
• These anatomical variations are often undetected by standard pre-operative imaging.
• Undetected variations can lead to surgical challenges and iatrogenic injuries during laparoscopic cholecystectomy (LC).

Purpose of the Study:

• To report an undescribed anomaly of the biliary tree encountered during a laparoscopic cholecystectomy.
• To highlight the potential for unexpected anatomical variations to complicate surgical procedures.
• To contribute to the existing literature on biliary duct anomalies.

Main Methods:

• A case report of a 53-year-old female patient undergoing laparoscopic cholecystectomy.
• Intraoperative identification and documentation of an unusual biliary duct anomaly.
• Review of relevant medical literature for previously described anomalies.

Main Results:

• A unique anomaly was identified: a high insertion of the cystic duct into the fundus of the gallbladder.
• This specific anomaly has not been previously documented in existing medical literature.
• The anomaly presented a surgical challenge during dissection in Calot's triangle.

Conclusions:

• Awareness of potential biliary tree variations is crucial for surgeons performing laparoscopic cholecystectomy.
• Undescribed anomalies, such as the one presented, can pose unexpected difficulties.
• Further documentation of rare biliary anomalies is important for surgical planning and patient safety.
