BACKGROUND: The standard treatment for Mirizzi syndrome is surgical, although endoscopic and percutaneous management have also been described. The aim of this study was to evaluate the usefulness of shock wave lithotripsy combined with peroral cholangioscopy and its long-term outcome in patients with Mirizzi syndrome.
METHODS: The records of 25 patients with Mirizzi syndrome who underwent endoscopic treatment between April 1990 and November 1998 were retrospectively reviewed. Shock wave lithotripsy was performed under direct vision with a "mother-baby" endoscope system in 2 patients with type I and 23 with type II Mirizzi syndrome (12 men and 13 women, mean age 60 years). Follow-up data were obtained from clinical records or through telephone interviews.
RESULTS: In the two patients with type I, the cholangioscopic approach failed and both patients underwent open cholecystectomy. The 23 patients with type II were all successfully treated with shock wave lithotripsy alone. The cholangioscopic approach was unsuccessful in the treatment of residual gallbladder stones. Follow-up data were obtained in all but one patient (mean 43.6 months, range 4 to 103 months). Of the 23 patients with type II, 12 with no gallbladder stones had remained asymptomatic during the follow-up period. Of the 6 patients with type II with large residual gallbladder stones, 4 had acute cholangitis due to stone migration 6, 9, 28, and 34 months after endoscopic treatment. Two patients died during the follow-up period, one of non-biliary causes and the other of coexistent gallbladder carcinoma.
CONCLUSIONS: Endoscopic treatment of Mirizzi syndrome using peroral cholangioscopy is a safe and effective alternative to surgery, especially in patients with the type II syndrome. A favorable long-term outcome depends on the absence of large residual gallbladder stones.
