Mirizzi syndrome: history, present and future development
1Department of Surgery, Prince of Wales Hospital, Chinese University of Hong Kong, Shatin, New Territories, Hong Kong.
Background:
Mirizzi syndrome was reported in 0.3-3% of patients undergoing cholecystectomy. The distortion of anatomy and the presence of cholecystocholedochal fistula increase the risk of bile duct injury during cholecystectomy.
Methods:
A Medline search was undertaken to identify articles that were published from 1974 to 2004. Additional papers were identified by a manual search of the references from the key articles.
Results:
A preoperative diagnosis was made in 8-62.5% of cases. Open surgical treatment gave good short-term and long-term results. There was a lack of good data in laparoscopic treatment. Conversion to open surgery rates was high, and bile duct injury rate varied from 0 to 22.2%.
Conclusion:
A high index of clinical suspicion is required to make a preoperative or intraoperative diagnosis, which leads to good surgical planning to treat the condition. Open surgery is the gold standard. Mirizzi syndrome should still be considered as a contraindication for laparoscopic surgery.
Insights
Mirizzi syndrome, a complication of gallstones, increases bile duct injury risk during gallbladder removal. High suspicion and open surgery are recommended due to limited laparoscopic data and high conversion rates.
Area of Science:
- Gastroenterology
- Hepatobiliary Surgery
Background:
- Mirizzi syndrome affects 0.3-3% of patients undergoing cholecystectomy.
- Anatomical distortion and cholecystocholedochal fistula increase bile duct injury risk.
Purpose of the Study:
- To review the diagnosis and surgical management of Mirizzi syndrome.
- To evaluate outcomes of different surgical approaches.
Main Methods:
- A systematic literature search was conducted using Medline (1974-2004).
- References from key articles were manually reviewed.
Main Results:
- Preoperative diagnosis rates ranged from 8-62.5%.
- Open surgery demonstrated good short- and long-term outcomes.
- Laparoscopic treatment data was limited, with high conversion rates and variable bile duct injury (0-22.2%).
Conclusions:
- High clinical suspicion is crucial for preoperative/intraoperative diagnosis and surgical planning.
- Open surgery remains the gold standard for Mirizzi syndrome.
- Mirizzi syndrome should be considered a contraindication for laparoscopic surgery.
