Histological studies and morphometry quantitative analysis have been performed on trial rabbit’s dilated common bile duct(CBD),which does not dilate simultaneously.The results shows:①Epithelia of rabbit’s CBD have a ber reparable function,which is fairly significant to the prevention of bile duct’s further injure under the pathogenic situation.②The smooth muscle cell(SMC)of the CBD is the histological basis of contraction,some SMC can be seen in contracting state under light microscope.This indicates that the SMC in rabbit’s CBD possess contracting function.③The collagenous and elastic fibers have the normal histological morphometric characteristics and quantity in it’s dilatation process,and no breekdown and degeneration of the fibers can be detected.Because of the morphological structure of these sections is quite similiar with normal ones,theoretically,we suspect that when pathological change of bile duct’s distal portion is relieved and the bile pressure is normal again.It is possible for this dilating bile duct to return to its formal shape and size.
Objective To prevent bile duct injury, a new anatomy marker, named “common bile duct window” is created. Methods From November 2005 to March 2006, 60 patients who underwent laparoscopic cholecystectomy were researched in this hospital. All data were collected, including: age, gender, course of disease, body mass index (BMI), blood lipid level (triglyceride and cholesterol), the thickness of gallbladder wall and the degree of cholecystitis. The frequency, location and mean size of “common bile duct window” were recorded and calculated. Patients were divided into two groups according to the presence of “common bile duct window”, and the diference of data between two groups was analyzed by using χ2 test or t test. Results “Common bile duct window” was found at the end of hepatoduoduenal ligament with oval-shaped, the mean longitude of “common bile duct window” was (1.20±0.60) cm, and mean width was (0.45±0.30) cm. “Common bile duct window” were found in 81.6% (49/60) of patients. Age, gender, course of disease, BMI, triglyceride and cholesterol were proved to have no relationship with the presence of “common bile duct window” （Pgt;0.05）, but the thickness of gallbladder wall and the degree of cholecystitis affected the presence （P＜0.05）. Conclusion An oval-shaped “common bile duct window” can be found in almost all patients undergoing laparoscopic cholecystectomy. During the operation, the common bile duct can be located easily by the surgeon through “common bile duct window”, thereby to avoid common bile duct injury when the cyst duct was dissected. It is believed that during laparoscopic cholecystectomy the chances of bile duct injuries can be effectively decreased by the presence of “common bile duct window”.
ObjectiveTo evaluate the value of magnetic resonance cholangiopancreatography (MRCP) on prevention of the complications in laparoscopic cholecystectomy (LC). MethodsThe clinical data of 1 079 patients underwent LC from January 2006 to June 2010 in this hospital were retrospectively analyzed. According to the use of MRCP or not in the different period, the patients were divided into nonMRCP group (n=523) and MRCP group (n=556). The occurrence of bile duct injuries (BDI) and retained common duct stone (RCDS) were compared between two groups. ResultsConversion to open surgery was performed in 35 cases in nonMRCP group and in 41 cases in MRCP group. The intraoperative and postoperative BDI were found in five patients and RCDS were found in 27 patients in nonMRCP group, and those were not found in patients in MRCP group. The differences of BDI and RCDS of patients were significant between two groups (P=0.026 and P=0.000). In nonMRCP group, 23 of 55 patients were found common bile duct stones by intraoperative cholangiography. Common bile duct stones were found by intraoperative cholangiography other than preoperative MRCP in three patients in MRCP group, while another three patients did not find common bile duct stones by intraoperative cholangiography although preoperative MRCP suggested. By MRCP, double gallbladders were found in one patient, Mirizzi syndrome in eight patients, variant cystic duct in 34 patients, accessory hepatic duct in 28 patients, and complicating common bile duct stones in 27 patients in MRCP group, the diagnostic accuracy of those were 100%, 87.5%, 94.1%, 89.3% and 88.9%, respectively. ConclusionPreoperative MRCP is helpful to prevent BDI and RCDS for the patients with LC.
Objective To investigate the feasibility and patient selection of T-tube free laparoscopic common bileduct exploration through mini-incision in confluence of common bile duct （CBD） and cystic duct. Methods The clinical data of 52 patients who underwent CBD exploration from January 2009 to December 2011 were retrospectively analyzed. A 3-4mm longitudinal incision of anterior wall of CBD was made along the confluence of CBD and cystic duct， and then the choledochoscope was inserted into CBD through this mini-incision for the exploration and treatment by laparoscopy and choledochoscopy， the incision was sewed up by T-tube free primary suture. Results All 52 cases were cured and stone clearance rate was 100% as revealed by choledochoscopy and cholangiography. The time of operation， intraoperativecholangiography， removal of stones with help of choledochoscope， and removal drainage tube after operation was from 90 to 200 min with an average of 100min， 3 to 10min with an average of 6min， 5 to 15 min with an average of 8 min，and 3-5d with an average of 3.5d ， respectively. The drainage flow was 20-60mL/d with an average of 30mL/d. No biliary leakage， abdominal pain， and choloplania or infection of incision was observed following operation. The hospital stay was 5 to 12d with an average of 6.5d after operation. No calculus regeneration or bile duct stricture occurred during following-up of 3 to 40 months with an average of 20 months. Conclusion With proper patient selection， T-tube free laparoscopic CBD exploration through mini-incision in confluence of CBD and cystic duct is safe and feasible by proficient surgeons in laparoscopy and choledochoscopy.
ObjectiveTo investigate the efficacy and safety of laparoscopic cholecystectomy and common bile duct exploration(LCBDE) with biliary stent drainage or T tube drainage. MethodsThe clinical data of 68 cases of gallbladder and bile duct stones with the LCBDE by the same surgeon in our hospital from June 2008 to June 2013 were retrospectively analyzed. Twenty-two patients were treated with LCBDE and biliary stent drainage(stent drainage group), 46 patients were treated with LCBDE and T tube drainage(T tube drainage group). ResultsThe operation were successfully completed of 2 groups. The anal exhaust time, peritoneal drainage time, postoperative hospitalization time, and hospital expenses in stent drainage group were shorter or less than thoes T tube drainage group(P < 0.05). There were no significant difference in the operative time, postoperative bilirubin level, and incidences of postoperative complications between the two groups(P > 0.05). ConclusionsThe stent drainage and T tube drainage after LCBDE has its own indications. Laparoscopic common bile duct exploration and biliary stent drainage is superior to the laparo-scopic common bile duct exploration and T tube drainage.
ObjectiveTo summarize the clinical experience on primary suture after common bile duct exploration and to investigate its clinical indications and curative effects. MethodsThe clinical data of 137 patients underwent primary closure of common bile duct between February 2006 and June 2010 were analyzed retrospectively. ResultsAll operations were successful. The operative time ranged from 65-213 min (mean 129 min) and the blood loss ranged from 50-350 ml with an average of 148 ml. One hundred and twenty-four patients (90.5%) were discharged from hospital without complications within 7 d after operation. Postoperative bile leakage occurred in 13 patients (9.5%) consisted of 10 early stage cases (18.5%, 10/54) and 3 later stage cases (3.6%, 3/83), which were discharged with improvement by conservative treatment within 3 weeks after operation. Totally 113 patients (82.5%) were followed up for 2-54 months with a median time of 14 months, no residual or retained stone and biliary duct stricture occurred. ConclusionOnly with the strict indication and proficient surgical technology, primary suture after common bile duct exploration is a safe and effective way to choledocholithiasis.
Objective To study the effect of laparoscopic common bile duct exploration via choledochotomy and T tube drainage. Metheods Laparoscopic exploration of common bile duct with choledochoscopy via choledochotomy was performed in 105 patients, T tube was placed in all patients with laparoscopic suturing technique.Results Except negative exploration in 2 cases, duct clearance was achieved in 99 per cent (102/103) of patients. Conclusion Laparoscopic exploratoin of common bile duct via choledochotomy and T tube drainage is one of the safe and effective management options for common bile duct calculi.
ObjectiveTo explore how to select the suitable indications of ERCP for clinical diagnosis and treatment. MethodsThe data of patients treated by ERCP between January 2005 and December 2009 in our hospital were analyzed retrospectively. ResultsTotal 221 patients received ERCP, among whom 99 (45%) cases of common bile duct stones, 44 (20%) cases of malignant tumor, 9 (4%) cases of papilla narrow, 45 (20%) cases were negative, and 24 (11%) cases were failed. It had the trend that the number of the patients received ERCP reduced year by year. The postoperative complication rate was 11% (25 cases), including 15 cases of postoperative pancreatitis, 3 cases of bleeding, 5 cases of biliary duct infection, and 2 cases of basket stranded. ConclusionIn the modern medical condition, with the advancement of image and laparoscopy technology, we should select the diagnosis and treatment methods with the principles of no damage or less damage for patients, without unlimitedly broadening the clinical indications of ERCP.
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.
ObjectiveTo compare the cost-effectiveness between endoscopic retrograde cholangio-pancreatography (ERCP) treatment and laparotomy treatment for simple common bile duct stone or common bile duct stone combined with gallbladder benign lesions. MethodsA total of 596 patients with common bile stone received ERCP (ERCP group) and 173 received open choledocholithotomy (surgical group) in our hospital between January 2009 and December 2012. Their clinical data were retrospectively analyzed. The curing rate, postoperative complications, hospital stay, preoperational preparation and total cost were compared between the two groups of patients. Meanwhile, for common bile stone combined with gallbladder benign lesion, 29 patients received ERCP combined with laparoscopic cholecystectomy (LC) (ERCP+LC group), 38 received pure laparoscopy treatment (laparoscopy group) and 129 received open choledocholithotomy combined with cholecystectomy (surgery group). ResultsFor simple common bile stone patients, no significant difference was found in cure rate and post-operative complication between endoscopic and surgical treatment groups (P>0.05). However, total hospitalization expenses[(13.1±6.3) thousand yuan, (20.6±7.5) thousand yuan)], hospital stay[(8.91±4.95), (12.14±5.15) days] and preoperative preparation time[(3.77±3.09), (5.13±3.99) days] were significantly different between the two groups (P<0.05). For patients with common bile stone combined with gallbladder benign lesion, no significant discrepancy was detected among the three groups in curing rate and post-operative complications (P>0.05). Significant differences were detected between ERCP+LC group and surgical group in terms of total hospitalization expense[(18.9±4.6) thousand yuan, (23.2±8.9) thousand yuan] hospital stay[(9.00±3.74), (12.47±4.50) days] and preoperative preparation time[(3.24±1.83), (5.15±2.98) days]. No significant difference was found in total hospitalization expense and hospital stay, while significant difference was detected in preoperative preparation time between ERCP+LC group and simple LC group. ConclusionFor patients with simple common bile stone, ERCP is equivalent to surgery in the curing rate, and has more advantages such as less cost, shorter length of hospital stay, and lower preoperative preparation time. For the treatment of common bile duct stone with gallbladder benign disease, ERCP combined with LC also has more advantages than traditional surgery.
