Objective To evaluate the efficacy and safety of small-middle endoscopic sphincterotomy combined with endoscopic papillary balloon dilation for patients with extrahepatic bile duct stone. Methods The patients with special duodenal papilla included 38 cases, and those with normal duodenal papilla 143 cases. 38 patients had received SEST + EPBD, 143 had received MEST + EPBD. Results 181 patients had received SMEST + EPBD in our hospital and the related data were retrospectively analyzed. All 181 patients were successfully removed, the success rate was 100.00 %. There was no perforation occurred postoperatively, but mild acute pancreatitis occurred in 8 patients (4.42 %, 8/181) and bleeding occurred in 9 patients. The three major early complications rate were 9.93 %(17/181), which was cured by the conservative management. Conclusion SMEST plus EPBD is a safe and effective treatment for extrahepatic bile duct stone, with retaining the feature of sphincter of duodenal papilla, especially for patients with special duodenal papilla.

Analysis of clinical efficacy of LTCBDE in patients with secondary extrahepatic bile duct stones / 实用医学杂志

Objective To investigate the effect of laparoscopic cholecystectomy (LTCBDE) in treatment of patients with secondary extrahepatic bile duct stones. Methods Eighty-seven cases of our hospital patients with secondary to extrahepatic bile duct stones were randomly divided into the laparoscopic bile duct exploration and T tube drainage surgery (LCBDE) treatment group and the laparoscopic transcystic duct exploration of common bile duct lithotomy (ltcbde) treatment group. The observation focused on the operation time, bleeding volume , postoperative transfusion , postoperative drainage time , postoperative hospitalization time , cost of hospitalization, postoperative recovery time and complications compared clinical efficacies. Results LTCBDE group of patients in operation time (2.1 ± 0.5) was longer than that of the control group (1.6 ± 0.4), (P <0.001), while the bleeding volume, postoperative fluid volume, postoperative drainage time, postoperative hospitalization time, hospitalization expenses and postoperative recovery time were (17.4 ± 5.4), (6 550.4 ± 1 076.9), (3.5. 1.6), (4.1 ± 1.7), (12 243.5 ± 2 379.6), (11.3 ± 3.5) were lower than that of the group LCBDE (22.1 ± 7.5), (8 304.2 ± 1 394.8), (32.9 ± 10.4), (6.4 ± 2.4), (14 098.1 ± 2 897.3), (16.1 ± 5.7) P, respectively (P values were defined as 0.001, 0, 0, 0.015, 0.001, 0 individually); LTCBDE group of patients with bile leakage, acute peritonitis rates were 1/46,1/46,in which those were lower than the corresponding LCBDE in 6/41, 7/41 (P values were 0.033, 0.016, separately). Conclusion According to indications, LTCBD surgery has the advantages of less injury, less cost, less complications and so on. It has important significance to improve the condition of patients with secondary extrahepatic bile duct stones.

Theraneutic effects of endoscopic sphincterotomy and endoscopic papillary balloon dilation for extrahepatic bile duct stones / 中华消化内镜杂志

Objective To study the safety and efficacy of endoscopic sphincterotomy (EST) and endoscopic papillary balloon dilation (EPBD) in the treatment for extrahepatic bile duct stones.Methods A total of 164 patients underwent endoscopic treatment for extrahepatic bile duct stones.Seventy eight underwent EST and EPBD (the EST + EPBD group),86 others underwent EST only (the EST group).The complication rate,complete stone clearance rate and gravel incidence rate were compared between the two groups.Results Hyperamylasemia occurred in 3 cases,mild acute pancreatitis in 2 cases of the EST and EPBD group,while hyperamylasemia occurred in 5 cases,mild acute pancreatitis in 3 and hemorrhage in 2 of the EST group.There were no severe complications like severe acute pancreatitis or intestinal perforation.The complication rate of the EST + EPBD group ( 6.4％,5/78 ) was slightly lower than that of the EST group ( 11.6％,10/86),(x2 =1.340,P =0.288),so was gravel incidence (33.3％ vs.60.5％,x2 =12.073,P =0.001 ).While complete stone clearance rate of this group was obviously higher than that of the EST group (100.0％ vs.93.0％ ),(x2 =5.649,P=0.030).Conclusion EST combined with EPBD is safe and effective for extrahepatic bile duct stone removal,especially for large stones or poor duodenal papilla.

Combination of endoscopy and laparoscopic hepatectomy in the treatment of intra-and extrahepatic bile duct stones / 中华消化外科杂志

Objective To study the approach of the combination of endoscopy and laparoscopic hepatectomy in the treatment of intra-and extrahepatic bile duct stones.Methods Eighty-one patients with intra-and extrahepatic bile duct stones who had been admitted to Nankai Hospital from July 2004 to March 2008 were divided by random number table into 2 groups.Twenty patients in group A underwent open hepatectomy+biliary exploration.Sixty-one patients in group B received duodenoscopy first,and patients with successful clearance of stones in the extrahepatic bile duct underwent total laparoscopic hepatectomy or hand-assisted laparoscopic hepateetomy according to the location of the stones in the liver;patients with residual stones in the extrahepatic bile duct underwent hand-assisted laparoscopie hepateetomy+biliary exploration.The changes of the indexes during perioperative period of the 2 groups were analyzed by t test.Results Minimally invasive surgeries were successfully carried out in group B.Satisfactory outcomes were obtained,and no severe complication was observed.The gastrointestinal function recovery time of patients who underwent hand-assisted laparoscopic hepatectomy+biliary exploration in group B was significantly shorter than in group A(t:3.062,P＜0.05),but there was no significant difference in operation time and perioperative blood loss between the 2 groups(t=0.953,0.911,P＞0.05).Compared with patients who underwent hand-assisted laparoscopic hepateetomy,the operation time was significantly longer,hut the gastrointestinal function recovery time was significantly shorter in patients who underwent total laparoscopic hepatectomy(t:2.046,2.316,P＜0.05),there was no significant difference in operation time between the 2 groups(t=0.874,P＞0.05).Conclusion Endoscopy+laparoscopic hepatectomy is safe and effective,and can decrease the trauma to the minimum for patients with intra-and extrahepatic bile duct stones.

Percutaneous Treatment of Extrahepatic Bile Duct Stones Assisted by Balloon Sphincteroplasty and Occlusion Balloon

OBJECTIVE: To describe the technical feasibility and usefulness of extrahepatic biliary stone removal by balloon sphincteroplasty and occlusion balloon pushing. MATERIALS AND METHODS: Fifteen patients with extrahepatic bile duct stones were included in this study. Endoscopic stone removal was not successful in 13 patients, and two patients refused the procedure due to endoscopy phobia. At first, all patients underwent percutaneous transhepatic biliary drainage (PTBD). A few days later, through the PTBD route, balloon assisted dilatation for common bile duct (CBD) sphincter was performed, and then the stones were pushed into the duodenum using an 11.5 mm occlusion balloon. Success rate, reason for failure, and complications associated with the procedure were evaluated. RESULTS: Eight patients had one stone, five patients had two stones, and two patients had more than five stones. The procedure was successful in 13 patients (13/15). In 12 of the patients, all stones were removed in the first trial. In one patient, residual stones were discovered on follow-up cholangiography, and were subsequently removed in the second trial. Technical failure occurred in two patients. Both of these patients had severely dilated CBD and multiple stones with various sizes. Ten patients complained of pain in the right upper quadrant and epigastrium of the abdomen immediately following the procedure, but there were no significant procedure-related complications such as bleeding or pancreatitis. CONCLUSION: Percutaneous extrahepatic biliary stone removal by balloon sphincteroplasty and subsequent stone pushing with occlusion balloon is an effective, safe, and technically feasible procedure which can be used as an alternative method in patients when endoscopic extrahepatic biliary stone removal was not successful.

Overall Success and Factors Predicting Failure for Endoscopic Extrahepatic Biliary Stone Extraction / 대한내과학회지

OBJECTIVES: Developments in endoscopic technique and equipments have improved duct clearance rate in patients with extrahepatic bile duct(EHBD) stone. In this study, we reviewed our experience in extracting EHBD stones with standard and more advanced technique and equipments such as mechanical lithotripsy and extra corporeal shock wave lithotripsy. Aims of this study were to determine the overall success rate of endoscopic ex tracting for EHBD stone, to identify risk factors for failed duct clearance at initial and final therapeutic ERCP. METHODS: We retrospectively reviewed 214 consec utive patients who underwent Endoscopic Retrograde Cholangiopancreatography(ERCP) for EHBD stone over 45 months period. Factors evaluated for failed duct clearance included stone size, stone number, stone shape, concomitant stone of gallbladder and intrahepatic duct, presence of distal bile duct stricture, periampullary diverticula(PAD), Billroth-II gastrojejunostomy, and sepsis at admission. RESULTS: The overall success rate of endoscopic treatment for EHBD stone was 93.5% (200/214). The causes of failed duct clearance were failed endoscopic sphincterotomy in 5/214 (2.3%), technical failure of extracting stone in 5/214(2.3%), and aggravation of acute cholecystitis between therapeutic endoscopic sessions in 4/214(1.9%). Risk factors for failed duct clearance with endoscopic extraction of EHBD stone were size and shape of the stone, concomitant stone of gallbladder and intra hepatic duct, and stricture of distal common bile duct. The duct clearance rate with initial therapeutic ERCP was 56.5%(121/200). Risk factors for failed duct clearance with initial therapeutic ERCP were size, shape and number of stone, and sepsis at admission. The com plications of endoscopic treatment for EHBD stone were major bleeding in 5/200 (2.5%), pancreatitis in 18/200 (9.0%), but there was no perforation. CONCLUSION: Eventhough risk for failure of endo scopic treatment for EHBD stone were giant or piston shaped stone, concomitant stone of gallbladder and intra hepatic duct, and stricture of distal common bile duct, we conclude that endoscopic treatment for EHBD stone is safe and effective treatment modality, and choice of treatment.
