BACKGROUNDReflux cholangitis has been the most common complication after Roux-en-Y choledochojejunostomy. In this study we intended to evaluate the perioperative and long-term efficacy of a new anastomosis method for choledochojejunostomy.

METHODSClinical data of 143 eligible patients who underwent choledochojejunostomy in the Eastern Hepatobiliary Surgery Hospital affiliated to the Second Military Medical University, China between January 2007 and December 2010 were retrospectively analyzed. 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.

RESULTSThere 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).

CONCLUSIONSPatients 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.

OBJECTIVE: To demonstrate a comprehensive review of published articles regarding endoscopic ultrasound (EUS)-guided biliary drainage. MATERIALS AND METHODS: Review of studies regarding EUS-guided biliary drainage including case reports, case series and previous reviews. RESULTS: EUS-guided hepaticogastrostomy, coledochoduodenostomy and choledoantrostomy are advanced biliary and pancreatic endoscopy procedures, and together make up the echo-guided biliary drainage. Hepaticogastrostomy is indicated in cases of hilar obstruction, while the procedure of choice is the coledochoduodenostomy or choledochoantrostomy in distal lesions. Both procedures must be performed only after unsuccessful ERCPs. The indication of these procedures must be made under a multidisciplinary view while sharing information with the patient or legal guardian. CONCLUSION: Hepaticogastrostomy and coledochoduodenostomy or choledochoantrostomy are feasible when performed by endoscopists with expertise in biliopancreatic endoscopy. Advanced echo-endoscopy should currently be performed under a rigorous protocol in educational institutions.

BACKGROUNDIt is difficult and time-consuming for carrying out conventional hand-sewn bilioenteric anastomosis, especially for small bile duct anastomosis and laparoscopic procedure. In order to simplify it, we have developed a novel procedure of sutureless bilioenteric anastomosis with an intraluminal degradable stent. This study aimed to evaluate the feasibility and safety of this technique with cholangioduodenostomy in dog model.

METHODSA patent intraluminal degradable stent tube for sutureless choledochoduodenostomy in dog model was made with polylactic acid in diameter of 3 mm or 4 mm. Thirty-eight dogs were randomly divided into to a stent group (SG, n = 20) and a control group (CG, n = 18). Dogs in the SG underwent sutureless choledochoduodenostomy with intraluminal stent, while the CG underwent conventional choledochoduodenostomy (single layer discontinuous anastomosis with absorbable suture). Dogs of each group were divided into 4 subgroups according to time of death (1, 3, 6, and 12 months postoperatively) to evaluate the healing of anastomosis. Operation time, intraoperative tolerance pressure of anastomosis, rate of postoperative bile leakage, bursting pressure of anastomosis were compared between the two groups. Anastomosis tissue was observed afterwards by pathology evaluation, hydroxyproline content, serum bilirubin, liver enzyme level and magnetic resonance cholangio-pancreatography (MRCP) to assess the stricture.

RESULTSAll procedures were completed successfully. The surgical time of the SG was significantly less than the CG (SG: (19.2 ± 4.3) minutes, vs. CG: (29.2 ± 7.1) minutes, P = 0.000). One bile leakage was occurred in either group. No significant difference of intraoperative tolerance pressure of anastomosis, rate of bile leakage and postoperative bursting pressure of anastomosis, anastomotic stricture, hydroxyproline content, serum bilirubin and liver enzyme level was found between the two groups. MRCP showed no anastomosis stricture and obstruction during months of follow-up.

CONCLUSIONThe technique of sutureless choledochoduodenostomy with a degradable intraluminal stent is feasible and a safe procedure in this dog model.

We report a rare case of a massive fatal embolism that occurred in the middle of endoscopic retrograde cholangiopancreatography (ERCP) and retrospectively examine the significant causes of the event. The patient was a 50-year old female with an uncertain history of previous abdominal surgery for multiple biliary stones 20 years prior. The patient presented with acute right upper quadrant pain. An abdominal computed tomographic (CT) scan revealed the presence of multiple stones in the common bile duct (CBD) and intra-hepatic duct (IHD) with biliary obstruction, multifocal liver abscesses, and air-biliarygram. Emergency ERCP showed a wide and straight opening of choledochoduodenostomy, which may have been created during a previous surgery, and multiple filling defects in the CBD. With the use of a forward endoscope, mud stones were extracted through the opening of the choledochoduodenostomy. Cardiac arrest suddenly developed during the procedure, and despite immediate resuscitation, the patient died due to a massive systemic air embolism. We reviewed previously reported fatal cases and accessed factors facilitating air embolisms in this case.

OBJECTIVETo study the characters of chronic pancreatitis complicated by non-calculous obstructive jaundice, and discuss the methods for differentiation and treatment.

METHODTwenty cases selected from January 1985 to December 2004 were analysed in the fields of differentiation and treatment.

RESULTSAll cases didn't present with typical clinical presentations and radiological features. Jaundice was presented as the main complaint. Stricture of the intra-pancreatic common bile duct was the symbolic radiological feature. Pancreatic disseminated inflammation was verified pathologically in these cases. CT, ultrasound, EUS, ERCP, MRCP and antigen-marker of neoplasm failed to offer the data for differentiation. The diagnosis could only be determined by pathological exam. The obstructive jaundice could be solved by biliary-enteric anastomoses successfully.

CONCLUSIONSThe patients with sole complaint of obstructive jaundice account for 15% of all inpatients with chronic pancreatitis. There exists a direct relationship between the jaundice and the pancreatic inflammation. This disorder should be differentiated from total pancreatic carcinoma, but few differentiated material could be offered by preoperative studies. Pathological result derived from the tissue sample obtained within the exploration would be reliable for diagnosis. The bypass between biliary tract and intestine would be a safe and economical treatment method.

OBJECTIVETo evaluate the combined surgical therapy for calculi of intrahepatic duct.

METHODSOne hundred and eight cases of hepatolithiasis treated in our hospital from January 1986 to September 2003 were summarized and analyzed retrospectively. The primary surgery included 57 cases of biliary tract exploration and cholangiolithotomy, 26 cases of cholangiojejunostomy, and 25 cases of partial hepatectomy. Of these cases, 156 operations were performed totally. There were 36 patients undergoing two or more operations for cholangiolithiasis problem. Fiberoptic choledochoscopy was employed to examine and remove the residual stones during and after operation in all cases.

RESULTSThe residual stone rates were 57.89% (33/57), 26.92% (7/26), and 24.0% (6/25) for biliary tract exploration and cholangiolithotomy, cholangiojejunostomy, and partial hepatectomy, respectively. Fiberoptic choledochoscopy was utilized pre- and post-operatively for each patient, which was performed 2 to 9 times on each case. Following the combined treatment, the rate of residual stone after operation decreased to 12.96% (14/108).

CONCLUSIONSThe combined surgical therapy is valuable for resolving the problem of hepatolithiasis in most of the patients. Regarding the clinical outcomes of different surgical procedures, partial hepatectomy is superior to cholangiojejunostomy or biliary tract exploration and cholangiolithotomy. Fiberoptic choledochoscopy is also important to reduce the occurrence of residual stones and the rate of reoperation.

OBJECTIVETo evaluate the effects of primary duct closure and T-tube drainage in laparoscopy choledochotomy to treat the common bile duct stones.

METHODSThe enrollment of the patients was in accordance with 6 criteria. 55 patients with cholecystolithiasis and secondary common bile duct stones from January 2000 to February 2003 were treated with laparoscopic choledochotomy. The patients were randomly divided into two groups: primary duct closure group and T-tube drainage group. Their all data were recorded and studied prospectively,and patients were followed up after discharge.

RESULTSThere were 27 patients and 28 patients in primary duct closure group and T-tube drainage group respectively. The operation time and the results of following up between the two groups had no significant difference. Compared with T-tube drainage group, primary duct closure group had less the total quantity of postoperative transfusion and hospital costs, shorter postoperative hospital stay. The incidence of postoperative complications in primary duct closure group was 11.1% (3/27), and all of them were biliary complications. The incidence of postoperative complications in T-tube drainage group was 28.6% (8/28), and seven of them were biliary complications. The incidence of severe complications that needed reoperations was 10.7% (93/28), and all of them were caused by T-tubes. There was no mortality in two groups.

CONCLUSIONSThe primary duct closure in laparoscopic choledochotomy can avoid the deficiency of T-tube drainage, and it is feasible and safe and lower complications in treating the common bile duct stones, so we advocate it in appropriate cases.

OBJECTIVETo discuss the technique and its advantage on application of ultrasonic scalpel in laproscopic cyst excision with Roux-en-Y hepatoenterostomy.

METHODSForty-five cases were undergone laparoscopic cyst excision with Roux-en-Y hepatoenterostomy by ultrasonic scalpel. After intraoperative cholangiogram, the gallbladder and the dilated bile duct were completely excised by ultrasonic scalpel. Roux-en-Y hepatoenterostomy was performed extracorporeally through umbilical incision, then an end-to-side anastomosis was carried out intracorporeally.

RESULTSAll 45 cases were completely accomplished under laparoscope combined with ultrasonic scalpel. Median duration of operation was 4.2 h (3.5-6.0 h). Intraoperative bleeding was between 10-50 ml (median 15 ml). No complication were found during operation. All children were discharged in 3-9 d (median 5.5 d) after operation. Thirty-eight cases were followed up 1-18 months. No stenosis or ileus occurred. Liver functions were in normal level.

CONCLUSIONSTotal cyst excision with Roux-en-Y hepatoenterostomy by ultrasonic scalpel under the laparoscope was effective and safe for choledochal cyst. The most excellence was that clearly viewing during operation, less bleeding and injury, free of pain postoperation, microincision and scar.
