Twenty-six young mongrel dogs were randomly divided into five groups: four groups with different magnetic pressures and 1 group with a hand-suture anastomosis. Serum bilirubin levels were measured in all groups before and 1 wk, 2 wk, 3 wk, 1 mo and 3 mo after surgery. Daily abdominal X-ray fluoroscopy was carried out postoperatively to detect the path and the excretion of the magnet. The animals were euthanized at 1 or 3 mo after the operation, the burst pressure was detected in each anastomosis, and the gross appearance and histology were compared according to the observation.RESULTS: The surgical procedures were all successfully performed in animals. However, animals of group D(magnetic pressure of 0.4 MPa) all experienced complications with bile leakage(4/4), whereas half of animals in group A(magnetic pressure of 0.1 MPa) experienced complications(3/6), 1 animal in the manual group E developed anastomotic stenosis, and animals in group B and group C(magnetic pressure of 0.2 MPa and 0.3 MPa, respectively) all healed well without complications. These results also suggested that the time required to form the stoma was inversely proportional to the magnetic pressure; however, the burst pressure of group A was smaller than those of the other groups at 1 mo(187.5 ± 17.7 vs 290 ± 10/296.7 ± 5.7/287.5 ± 3.5, P < 0.05); the remaining groups did not differ significantly. A histologic examination demonstrated obvious differences between the magnamosis groups and the hand-sewn group.CONCLUSION: We proved that the optimal range for choledochojejunostomy magnamosis is 0.2 MPa to 0.3 MPa, which will help to improve the clinical application of this technique in the future.展开更多

Among the patients, 38 consecutive cases underwent this new anastomosis method for choledochojejunostomy （improved group, IG） and 105 underwent standard Roux-en-Y choledochojejunostomy （control group, CG）. Changes in the incidence of cholangitis, the time of beginning to eat liquid meals, post-operative delayed gastric emptying and liver function between the two groups were compared. Results There was no statistical difference in the levels of alanine transaminase, alkaline phosphomonoesterase and gamma-glutamy transferase between the two groups. The time of beginning to eat liquid meals was significantly shorter in IG than CG （P 〈0.05）. The incidence of delayed gastric emptying was lower in IG than CG, with statistical tendency between the two groups （P=0.052）. Among nine patients with different degrees of acute cholangitis in the two groups, one patient （2.6%） in IG and eight （7.6%） in CG suffered from acute cholangitis within six months of follow-up after discharge, but with no statistical difference between the two groups （P 〉0.05）. Of the nine patients with acute cholangitis, none in IG and four in CG were hospitalized for further treatment （P 〉0.05）. Conclusions Patients in IG had satisfactory perioperative and long-term prognosis with shorter time of beginning to eat liquid meals and lower incidence of delayed gastric emptying. This new procedure of choledochojejunostomy by the way behind antrue pyloricum was easy and safe to perform with no mortality and low complication rates.展开更多

METHODS: In 37 post-surgical patients, a stepwise approach was performed to reach normal papilla or enteral anastomoses of the biliary tract/pancreas. When conventional endoscopy failed, DBE-based ERCP was performed and standard parameters for DBE, ERCP and interventions were recorded. RESULTS: Push-enteroscopy (overall, 16 procedures) reached enteral anastomoses only in six out of 37 post-surgical patients (16.2%). DBE achieved a high rate of luminal access to the biliary tract in 23 of the remaining 31 patients (74.1%) and to the pancreatic duct (three patients). Among all DBE-based ERCPs (86 procedures), 21/23 patients (91.3%) were successfully treated. Interventions included ostium incision or papillotomy in 6/23 (26%) and 7/23 patients (30.4%), respectively. Biliary endoprosthesis insertion and regular exchange was achieved in 17/23 (73.9%) and 7/23 patients (30.4%), respectively. Furthermore, bile duct stone extraction as well as ostium and papillary dilation were performed in 5/23 (21.7%) and 3/23 patients (13.0%), respectively. Complications during DBE-based procedures were bleeding (1.1%), perforation (2.3%) and pancreatitis (2.3%), and minor complications occurred in up to 19.1%. CONCLUSION: The appropriate use of DBE yields a high rate of luminal access to papilla or enteral anastomoses in more than two-thirds of post-surgical patients, allowing important successful endoscopic therapeutic interventions.展开更多

MFTHODS: The clinical data on 232 patients with hilar cholangiocarcinoma in the last 22 years were analyzed retrospectively. Palliative operations included extrahepatic or intrahepatie choledochojejunostomy (123 patients), bridge internal drainage (15), endoscopic biliary drainage (49), percutaneous transhepatic biliary drainage or celiotomy biliary drainage (29), and exploratory celiotomy external drainage (16). RESULTS: In this series, the operative mortality rate was 9.1%, and no significant difference was observed between groups. The rate of cholangitis after operation was significantly lower in Roux-en-Y choledochojejunostomy group (16.2%) and bridge internal drainage group (15.4%) than in internal drainage group (35.5%, P<0.01), including percutaneous transhepatic biliary drainage (PTBD), endoscopic retrograde biliary drainage (ERBD), and celiotomy (or PTBD) external biliary drainage group (39.1%, P<0.01). No significant difference in survival was observed between the Roux-en-Y choledcthojejunostomy group (9.3±1.8 months) and PTBD (or ERBD) internal drainage group (8.7±2.2 months), but the survivals of the above groups were significantly longer than those of the bridge internal drainage group (6.5±1.7 months, P<0.05) and celiotomy (or PTBD) external biliary drainage group (4.4±2.1 months, P<0.01). CONCLUSIONS: In unresectable cholangiocarcinomas, either operative bilioenteric bypass or percutaneous transhepatic biliary drainage can achieve significant palliation. Roux-en-Y choledochojejunostomy is the best choice for palliative operation. The use of U-tube is recommended for internal radiation therapy.展开更多

Details of primary cholecystectomy,biliary reconstruction as well as postoperative ma-nagement were recorded. All patients were followedup for at least 6 months (6 months to 9 years, medi-an 3.5 years). The adequacy of repair was assessedby regular evaluation of the patients clinical statusand liver function variables. Hepatobiliary B-ultra-sonography was used routinely in the follow up of pa-tients, and magnetic resonance cholangiopancreatog-raphy was applied in the patients suggestive of abnor-mality.Results: In 152 patients, bile duct injury happenedduring open cholecystectomy, and in 30 patients dur-ing laparoscopic cholecystectomy. All the injuries de-veloped during anterograde cholecystectomy (at theCalot’s triangle). All the patients with these injuriesunderwent choledochocholedochostomy or Roux-en-Ycholedochojejunostomy with good results (161 pa-tients), recurrent stricture (11), and death (10).Conclusions: During cholecystectomy, the Calot’s tri-angle should be identified anatomically, but retro-grade cholecystectomy is the optimal choice. Bileduct injury should be discovered as soon as possibleand be managed timely. Different operative methodsare optional according to the degree of injury and thepostoperative period.展开更多
