Abstract Introduction Congenital choledochal malformations (CCMs) are characterized by intra- and/or extrahepatic bile duct dilatation. Five basic types (1–5) are recognized in Todani's classification and its modifications, of which types 1 and 4 typically have an associated anomalous pancreatobiliary junction and common channel (CC). We describe two cases with previously undescribed features. Case Report 1 Antenatal detection of a cyst at porta hepatis was made in an otherwise normal girl of Iranian parentage. She was confirmed to be a CCM (20 mm diameter), postnatally, with no evidence of obstruction. Surgical exploration was performed at 12 weeks. She had an isolated cystic dilatation of the right-hepatic duct only. The left-hepatic duct and common bile duct (CBD) were normal without a CC. Histology of the resected specimen showed stratified squamous epithelium. Case Report 2 A preterm (31 weeks of gestation) boy of Nigerian parentage was presented. His mother was HIV + ve and he was treated with nucleoside reverse transcriptase inhibitors following birth. He had persistent cholestatic jaundice and a dilated (10 mm) bile duct from birth. Although the jaundice resolved, the dilatation persisted and increased, coming to surgery aged 2.5 years. This showed cystic dilatation confined to the common hepatic duct, and otherwise normal distal common bile duct and no CC. Result Both underwent resection with the Roux-en-Y hepaticojejunostomy reconstruction to the transected right-hepatic duct alone in case 1, leaving the preserved left duct and CBD in continuity, and to the transected common hepatic duct in case 2. Conclusions Neither choledochal anomaly fitted into the usual choledochal classification and case 1 appears unique in the literature.

The permeability of the biliary epithelium to [14C]ursodeoxycholic acid (UDCA), a hypercholeretic bile acid, was compared to that of the 14C-labeled nonhypercholeretic bile acids cholic acid (CA), taurocholic acid (TCA), and tauroursodeoxycholic acid (TUDCA) by means of anterograde intrabiliary infusions and retrograde intrabiliary injections in the anesthetized rat. Anterograde intrabiliary infusions were performed by perfusing an isolated segment of common bile duct in vivo. After anterograde intrabiliary infusions, the fraction of unrecovered UDCA (that had presumably been absorbed from the biliary lumen) was 11.03 +/- 1.03 (SE)% (n = 6) of the administered dose. It was significantly higher than that of TUDCA (1.25 +/- 0.27%; n = 5; P less than 0.01), CA (2.62 +/- 0.43%; n = 4; P less than 0.01), and TCA (2.57 +/- 0.79%; n = 6; P less than 0.01). In separate experiments, bile was collected from the common bile duct and from the left hepatic duct. UDCA recovered from the left hepatic duct was found in the conjugated form, indicating that, after absorption in the common bile duct, it had been conjugated by the hepatocyte and secreted into bile. After retrograde intrabiliary injections of UDCA and CA, the cumulative percentages of recovered radioactivity were not significantly different (84.50 +/- 2.65 and 87.33 +/- 1.80%, respectively); however, peak recovery of UDCA was significantly delayed compared with that of CA. Moreover, UDCA was recovered mostly in the conjugated form, while CA was recovered mostly in the unconjugated form. These results suggest that, in the rat, UDCA is significantly more absorbed by the biliary tree than CA, TUDCA, and TCA. They support the hypothesis that UDCA undergoes a cholehepatic circulation.

AIM: This study aimed to analyze the causes, diagnosis, and clinical treatment of postoperative obstructive jaundice (POOJ) in routine surgical practice. MATERIALS AND METHODS: Twenty-four patients with POOJ that developed in the organs of the hepatobiliary system after surgical interventions were included in this study. The patients were subjected to the following procedures to diagnose the causes of POOJ and choose the treatment methods: general clinical examination, biochemical blood tests, dynamic postoperative ultrasound examination of the abdominal organs, video laparoscopy, computed tomography, magnetic resonance imaging, fistulocholangiography, endoscopic retrograde cholagiopancreatography, and percutaneous transhepatic cholangiostomy. RESULTS: POOJ occurred in 18 cases after they had different variants of surgical interventions on the biliary tract after traditional (n = 6) and video laparoscopic cholecystectomy (n = 12). POOJ also developed in 6 cases after they underwent surgery on the liver: atypical (n = 2) and anatomical (n = 2) resection of the liver. This condition manifested after the opening and draining of liver abscesses under US control (n = 2). POOJ was treated with different methods to alleviate the developed complications. After surgical interventions on the liver and biliary tract in 6 cases, relaparotomy, sequestrectomy with sanation, drainage of the abdominal cavity (n = 4), and right-sided hemihepatectomy (n = 2) were performed. In 6 other cases, on days 34 of the development of POOJ after laparoscopic operation (n = 2), relaparotomy was performed, clips and ligature were removed from the choledoch with the formation of Roux-en-Y hepaticojejunostomy. Minimally invasive methods of POOJ correction were applied to 12 cases. Of the 12 cases, 5, 2, and 1 were subjected to endoscopic papillosphincterotomy with lithoextraction, endoscopic papillosphincterotomy with lithoextraction coupled with nasobiliary drainage, and relaparoscopy and redrainage of the common bile duct, respectively. In 4 cases, percutaneous transhepatic cholangiostomy was performed at the first stage. At the second stage, after POOJ resolution, the following procedures were implemented: redrainage of the common bile duct (n = 2) and dilatation of the orifice of the right hepatic duct with reconstruction of hepaticojejunostomy on the hidden transhepatic drainage. CONCLUSION: POOJ is still encountered in clinical practice in a sufficient number of cases. Treatment results largely depend on the time of diagnosis and the choice of optimal surgical strategies. The main causes of POOJ are tactical and technical diagnostic and treatment errors. POOJ is diagnosed on the basis of the data of modern radiation and laboratory and instrumental examination methods. Surgical tactics for POOJ are individually active and dependent on the severity, time, and causes of development. They also depend on the general condition of patients. Along with minimally invasive interventions for POOJ, early relaparotomy is less dangerous than passive expectation tactics.

Anomalies in the biliary tract development are a relatively rare pathology in the practice of a pediatric surgeon. A combination of two or more defects of the biliary tract is even less common. The article presents literature data and own clinical observation of a child with a combination of a cyst of the common bile, or hepatic, duct (common bile duct) and an additional bile duct. The anatomical structure of the biliary tract was identified before surgery using magnetic resonance cholangiography. Based on the analysis of literature data and our own observation, we propose an algorithm for diagnostic measures in children with malformations of the biliary tract, which helps to avoid intraoperative injuries.

Increased Risk

To identify factors involved in choledocholithiasis, clinical characteristics were studied using univariate and multivariate analyses. Factors involved in recurrence were also investigated. The subjects consisted of 51 patients with calcium bilirubinate stones (B group) and 52 patients with cholesterol stones (C group). All patients had choledocholithiasis and underwent lithotripsy by endoscopic sphincterotomy (EST) during the past 9 years. Twenty variables, including clinical symptoms and endoscopic retrograde cholangiopancreatography (ERCP) findings, were analyzed using a Statistical Analysis System (SAS) software package. Univariate analysis were done using Student's t-test and the chi-square test. Multivariate analyses were done by stepwise logistic regression analysis. In univariate analyses, there were significant differences between the B group and C group in nine variables: age, common bile duct diameter, common hepatic duct diameter, common bile duct stone diameter, cystic duct diameter, and the presence of gallbladder stones, atypical arrangement of the hepatic duct, parapapillary diverticulum, and large parapapillary diverticulum. In multivariate analysis, the four variables of no gallbladder stone, large parapapillary diverticulum, cystic duct less than 8 mm, and atypical arrangement of the hepatic duct were significant independent factors for the development of stones in the B group, with relative risks of 37.75, 16.73, 5.56, and 5.49, respectively. The results indicated that calcium bilirubinate stones were frequently associated with parapapillary diverticulum and abnormal arrangement of the bile duct. The formation of these stones was attributed to chronic biliary stasis caused by dysfunction of the biliary tract, including the papilla. In contrast, most cholesterol stones found in the common bile duct had apparently descended from the gallbladder. Common bile duct stones recurred after EST in 9 patients, all of whom had calcium bilirubinate stones. On ERCP, recurrence was found to be frequently associated with gallbladder stones, large parapapillary diverticula, and atypical arrangement of the hepatic duct. Patients with these characteristics on initial ERCP should therefore receive appropriate treatment and undergo strict follow-up observations owing to the increased risk of recurrence caused by dysfunction of the biliary tract.

Further Development

The main causes of cholangitis are hypertension in the biliary ducts and infection. In order to determine the place of the infectious factor in the acute cholangitis development, a retrospective and prospective analysis of case histories of 176 patients with choledocholithiasis and manifestations of acute and chronic cholangitis was performed. Bile from the common bile duct in the patients with obstruction of the biliary tract was studied. In the patients with mechanical jaundice without and with cholangitis, the intraductal pressure in the common bile duct averaged 227.3±26.1 mm of water column, in the patients without signs of cholangitis that was 97.5±8.3 mm of water column. With mechanical jaundice without acute cholangitis, it was slightly elevated if compared to normal. This suggests that the increase in pressure in the bile ducts in acute cholangitis is not influenced by the fact of obstruction of the biliary tract, and the development of the inflammatory process in them. In the patients with cholangitis, the initial values of the number of colonizing units were much higher than in "pure" choledocholithiasis. After endoscopic papillosphincterotomy in the patients with vivid clinical cholangitis, in whom decompression was achieved, in the control study, this value decreased by 100−500 times, which was accompanied by clinical improvement. According to the results of the study, it was noted that in the patients with a manifested clinic sign of cholangitis there is a significant decrease in the number of colonizing units on the third day after endoscopic papillosphincterotomy. At the stone stuck in a papilla the choledoch turns into so−called analog of an abscess. The opening of the papilla provides a free passage of the contents of the choledochus (i.e. pus) into the duodenum, so there is an almost instant therapeutic effect. The increase in pressure in the bile ducts in acute cholangitis is influenced by the development of an inflammatory process, which indicates the manifestations of biliary infection. The presented research has a prospective character and needs further development. Key words: cholangitis, biliary infection, intraductal pressure, bile.
