Application of Laparoscopic Ultrasound in Cystic Duct Stone Surgery: A Retrospective Experience

Abstract To investigate the value of laparoscopic ultrasound (LUS) in the diagnosis of cystic duct stones and formulation of surgical strategies. Clinical data from 41 patients with cystic duct stones were retrospectively analyzed. LUS was used to evaluate stone distribution and assess the surrounding vasculature, thereby preventing residual stones. Additionally, LUS was used to detect concurrent common bile duct (CBD) stones or assess potential stone migration into the CBD. Thirty-nine patients underwent laparoscopic cholecystectomy (LC), and two patients underwent LC combined with CBD exploration. The mean postoperative hospital stay was 3.95 ± 1.02 days. During a 3-month to 1-year follow-up, no biliary complications occurred. LUS ensures safe and effective cholecystectomy for cystic duct stones by enabling real-time stone detection and preventing residual or migrated stones.
