Clinical Outcomes and Treatment Strategy of Mirizzi's Syndrome Treated With Surgery.

Background: There is currently no standardized treatment for Mirizzi's syndrome (MS). We aim to explore the surgical treatment strategy for MS by analyzing its clinical characteristics and treatment outcomes.

Methods: This retrospective study analyzed the clinical data of 130 patients with MS who underwent surgery at our hospital from April 2013 to April 2020.

Results: The study population comprised 130 patients with MS, with an approximately balanced sex ratio and a median age of 58.5 years. The preoperative diagnostic rate was 82.3%. The diagnostic accuracy of ERCP was 92.5%, higher than that of MRCP and ultrasound. All patients underwent surgical treatment, with 74 cases of laparoscopic surgery, 43 cases of laparotomy, and 13 cases of laparoscopic surgery converted to laparotomy. A total of 23 patients experienced short-term and long-term complications after surgery, with a complication rate of 17.7%. There was no statistical difference between laparoscopic surgery and open surgery in terms of intraoperative hemorrhage, operative time, and postoperative complication rate. However, the length of hospital stay was shorter in the laparoscopic surgery compared to the open surgery, which was statistically different from each other.

Conclusion: ERCP is the gold standard for the diagnosis of MS, especially for identifying the type of MS. ERCP plays an important role in both the preoperative and postoperative phases of MS. Our study demonstrated that laparoscopic surgery was a safe and feasible option for MS treatment, even requires less hospitalization than open surgery.
