[Clinical application of percutaneous cholecystolithotripsy]

From September 1990 to March 1991, 109 women and 41 men, aged 22-73, with symptomatic gallstones underwent percutaneous cholecystolithotripsy. The procedure is performed with the patient under epidural anesthesia. The fundus of gallbladder was pulled with forceps and fixed to the anterior abdominal wall, then the fundus of gallbladder was punctured and dilated, and gallstones were removed with a 23-F cholecystoscope under direct visual inspection. Larger stones were disintegrated with ultrasound lithotripsy, and small fragments aspirated or removed with forceps. In this group, all patients had a successful percutaneous cholecystolithotripsy, cure rate was 97.3%, only four (2.6%) had residual stones, there we ren't complications. The result shows percutaneous cholecystolithotripsy is a safe and effective technique, which is practicable and preferable when the stones are found within a gallbladder with normal drainage and normal contractility.
