Laparoscopic treatment for Mirizzi syndrome.

BACKGROUND

Mirizzi syndrome is an uncommon complication of longstanding gallstone disease resulting in obstructive jaundice and remains surgically challenging. Mirizzi syndrome is generally considered a contraindication to laparoscopic surgery. We present the surgical experience of 11 consecutive patients with Mirizzi syndrome who were diagnosed correctly preoperatively and treated laparoscopically.

METHODS

From January 1991 to December 2001, 4,560 patients underwent laparoscopic cholecystectomy for gallbladder lesions, 11 (0.24%) of whom were diagnosed with Mirizzi syndrome.

RESULTS

The 11 patients diagnosed with Mirizzi syndrome included four men and seven women, with ages ranging from 21 to 72 years (median, 54). There were 10 patients with Mirizzi syndrome type I (one was caused by gallbladder cancer in the neck), and 1 patient with type II, according to McSherry's classification. Right upper quadrant abdominal pain was the most common symptom, occurring in all 11 patients. All 11 patients were diagnosed correctly preoperatively by endoscopic retrograde cholangiography (ERCP) with 100% sensitivity. Four of the 11 patients (36.4%) were converted to open procedure. The postoperative course was uneventful, except for one patient complicated with a residual common bile duct stone. Hospital stay ranged from 4 to 33 days (median, 7).

CONCLUSIONS

Mirizzi syndrome is an uncommon disorder. Preoperative suspicion is crucial for correct preoperative diagnosis. ERCP is the most useful tool for correct preoperative diagnosis and consequent prevention of common bile duct injury during operation. Should Mirizzi syndrome be diagnosed, laparoscopic treatment is a feasible and safe procedure, especially for type I Mirizzi syndrome.
