  • Combination of Laparoscope, Choledochoscope, and Balloon Nasobiliary Exploration in Treatment of Cholecystolithiasis Combined with Choledocholithiasis with Small Diameter of Common Bile Duct (Report of 43 Cases)

    ObjectiveTo summarize clinical experiences of combination of laparoscope,choledochoscope,and balloon nasobiliary exploration (LCBNE) in treatment of cholecystolithiasis combined with choledocholithiasis with small diameter (0.3-0.8 cm) of common bile duct (CBD). MethodsFrom April 2010 to May 2015,there were 43 cases of cholecystolithiasis combined with choledocholithiasis with small diameter of CBD underwent LCBNE,involving choledochotomy,choledochoscopic exploration,electrohydralic lithothipsy,balloon nasobiliary dilatation for removing cholelith,nasobiliary drainage,and the primary closure of incision. ResultsThe procedure was successful in 27 cases of removing the bile duct residual stones through the choledochoscopic procedure,9 cases through the balloon nasobiliary procedure,and 7 cases were converted to endoscopic sphincterotomy for choledocholithasis.No case was converted to open CBD exploration.No case had residual stone.Bile leakage occurred in 1 case,which was cured by peritoneal drainage and nasobiliary drainage.One patient had a slight pancreatitis after operation.One patient had the stenosis of primary suture of CBD incision.Total postoperative complications rate was 7.0%(3/43).No case had perforations of intestine and bile duct,bleeding,severe pancreatitis,and death after operation. ConclusionFrom preliminary results of limited cases in this study,if patients are indicated,combination of LCBNE in treatment of cholecystolithiasis combined with choledocholithiasis with small diameter of CBD is safe and effective.

  • Application of MRCP in 998 Cases of Common Bile Duct Stones of Diameter in The Normal Range

    ObjectiveTo investigate the clinical value of MRCP and (or) MRI on combination of choledochoscopy and duodenoscopy during the course of therapeutic laparoscopy with preoperative or intraoperative help diagnosis and treatment of gallbladder stone with common bile duct stones of diameter in the normal range. MethodsThe clinical data of 998 patients with calculus of bile duct with diameter in the normal range of common bile duct (common bile duct diameter of 0.2-0.8 cm) by MRCP and (or) MRI assist in diagnosis and treatment from Oct. 2001 to Dec. 2015 in the Second People's Hospital of Chengdu City were retrospectively analized. ResultsThe 998 cases of common bile duct diameter≤0.8 cm were diagnosed and treated by using MRCP and (or) MRI examination. Choledochoscopy group: There were 399 cases, 352 cases (88.2%) were successful removed the bile duct residual stones through the choledochoscopic procedure, converted to intraoperative endoscopic sphincterotomy in 47 cases (11.8%). The false positive rate of MRCP and (or) MRI was 3.7% (13/352), the false negative rate of color Doppler ultrasound was 79.3% (279/352). Duodenoscopy treatment group: It was performed in 408 cases. The stones of common bile duct removed with duodenoscopic papillo-tomy in 381 cases (93.4%), the stone expulsion after duodenoscopic papillotomy in 18 cases (4.4%), 9 cases (2.2%) were shifted to other operation. False negative rate of color Doppler ultrasound was 79.5% (303/381). Three endoscopy group: There were 191 cases that intraoperative choledochoscopic exploration or intraoperative endoscopic papillotomy. The false positive rate of MRCP and (or) MRI was 2.6% (5/191), the false negative rate of color Doppler ultrasound was 76.4% (146/191). ConclusionsRoutine use of MRCP and MRI, in preoperative or intraoperative help diagnosis and treatment of gallbladder stone with common bile duct stones of diameter in the normal range, on combination of choledochoscopy and duodenoscopy during the course of therapeutic laparoscopy. It is necessary, feasible, effective and safe.

  • Application of Transabdominal Reverse Guided-Laparoscopic Endoscopic Sphincteropa Pillotomy: A Report of 501 Cases

    Objective To explore the operation methods and indications of the transabdominal reverse guided-laparoscopic endoscopic sphincterotomy in treatment of duodenal papilla stenosis during the course of laparoscopic common bile duct exploration. Methods The clinical data of 501 cases of duodenal papilla stenosis who underwent laparoscopic endoscopic sphincterotomy with the transabdominal reverse guide technique from March 2003 to July 2015 in the Second People’s Hospital of Chengdu city were analyzed retrospectively. Results All operation of the 501 cases were successful, no death happened. The operation time were 60-190 min (average of 107 min), the blood loss were 5-100 mL (average of 21.8 mL), and postoperative hospitalization time were 4-9 days (average of 6.7 days). It was successful in 501 cases that removed the gallbladder, and successful in 493 cases (98.4%) that removed the common bile duct stones out of 501 cases. Six cases (1.2%) had residual stones in T tube drainage and received treatment with postoperative choledochoscope and electrohydraulic lithotripsy. Two cases (0.4%) of primary suture had residual stones. In the 501 cases, 364 cases (72.7%) underwent directly implementation of primary suture after the success of papillary stenosis cutting, 9 cases (1.8%) underwent primary suture after indwelling ureteral catheter, 118 cases (23.5%) underwent primary suture after detaining nasobiliary drainage, 4 cases (0.8%) failed in cutting the papillary stenosis and 6 cases (1.2%) had residual stones, all the 10 cases turned into the T tube drainage. After the operation, 9 cases (1.8%) suffered from mild pancreatitis and 23 cases (4.6%) suffered from bile leakage, no perforation of intestine and bile duct, bleeding, severe pancreatitis, and other complications happened. The overall incidence of postoperative complication was 6.8% (34/501). Conclusion If patients are suitable, transabdominal reverse guided-laparoscopic endoscopic sphincterotomy in treatment of duodenal papilla stenosis is safe and effective.

  • REPAIR OF ACUTE CLOSED ACHILLES TENDON RUPTURES BY CHANNEL-ASSISTED MINIMALLY INVASIVE REPAIR SYSTEM

    ObjectiveTo evaluate the effectiveness of channel-assisted minimally invasive repair (CAMIR) for acute closed Achilles tendon ruptures. MethodsBetween January 2011 and June 2012, 30 patients (30 sides)with acute closed Achilles tendon ruptures were treated with CAMIR technique. Among 30 patients, 18 were male and 12 were female with an average age of 30.4 years (range, 22-50 years); the locations were left side in 10 cases and right side in 20 cases. All the causes were sports injury. B-ultrasound was used to confirm the diagnosis, with the average distance from the rupture site to the Achilles tendon insertion of 4.4 cm (range, 2-8 cm). The time from injury to operation was 3 hours to 9 days (median, 4 days). All injuries were repaired by CAMIR technique. ResultsThe average operation time was 17.0 minutes (range, 10-25 minutes), and the mean incision length was 2.0 cm (range, 1.5-2.5 cm). All the incisions healed by first intention. There was no complication of wound problem, deep vein thrombosis, re-rupture, or sural nerve injury. All cases were followed up 12-24 months with an average of 16 months. At last follow-up, the patients could walk normally with powerful raising heels and restored to normal activity level. MRI imaging suggested the continuity and healing of ruptured tendon. The circumference difference between affected leg and normal leg was less than 1 cm, and the ankle dorsi-extension was 20-30°, plantar flexion was 20-30°. Arner Lindholm score showed that the surgical results were excellent in 28 cases and good in 2 cases, with an excellent and good rate of 100%. ConclusionCAMIR is a safe and reliable method to repair acute closed Achilles tendon rupture, with many advantages of minimal injury, low re-rupture and infection. Sural nerve injury can be minimized using CAMIR by carefully placing the suture channel with a stab incision and special trocar based on a modified Bunnel suture technique.
