Objective To explore the feasibility and efficiency of laparoscopic surgery for the treatment of acute biliary pancreatitis (ABP) at early stage. Methods From January 2003 to June 2006, 18 patients with ABP received laparoscopic surgeries, including laparoscopic cholecystectomy (LC) in 3, LC combined with laparoscopic common bile duct exploration (LCBDE) in 9, LC combined with opening of the pancreatic capsule for drainage in 5, and LC combined with LCBDE and opening of the pancreatic capsule for drainage in 1. Results In all the patients, the laparoscopic operations were completed successfully without conversion to open surgery. The operation time was 100-150 min with a mean of (115.3?15.2) min. The stones in the bile duct were removed completely by LCBDE in 10 patients. No subcutaneous emphysema, hemorrhage, abdominal abscess or stenosis of the bile duct occurred in this series. The 18 patients were followed up for 4-40 months (mean, 28.5 months), during which 2 patients developed pancreatic pseudocyst. One of the patients was cured by internal drainage. In the other patient, the pseudocyst was absorbed spontaneously. No recurrence of pancreatitis or common bile duct stones was found. Conclusions Laparoscopic surgery is minimally invasive and effective for the treatment of ABP at early stage.

Objective To compare the efficacy of minimally invasive pereutaneous nephrosomy for complicated renal calculi between holimium laser hthotfipsy and ultrasonic lithotripsy.Methods 120 patients with renal calculi according to the different treatment methods,were divided into holimium laser lithotfipsy group 60 cases(group A)and tdtrasonic lithotripsy group 60 cases(group B).The index of operative time、hemoglobin drop blood transfusion rate、postoperative hospital stay、stone clearance rate were observed.Results Operative time(60.8±16.4)min,postoperative hospital stay(7.5±2.0)d in group A were shorter than[(80.5±18.5)min,(9.5±2.5)d]in group B (t=2.328,2.240,all P＜O.05);Hemoglobin decline(5.0%)in group A was lower than the(9.0%)in group B (x2=3.89,P＜0.05);Calculi clearance rate(81.7%)in the B group was highter than that(61.6%)in group B (x2=3.98,P＜0.05);Complication incidence of postoperative 10.O%in group A compared with group B 13.3%had no significant difference(x2=1.56,P＞0.05).Conclusion Percutaneous nephrostomy with ultrasonic lithotripter for complicated renal calculi had the advantages of mini-invasion,less operative time,less bleeding,and faster clearance calculi efficiency compared with laser lithotripsy.
