Gallbladder agenesis (GA) is a rare congenital anomaly of the biliary system often associated with other congenital abnormalities. Patients become symptomatic in 23% of cases. GA is often misinterpreted as other diseases, therefore, leading to unnecessary surgery. We report a case of congenital GA associated to cystic duct absence and a biliary tract abnormality diagnosed by Magnetic Resonance with Cholangiopancreatography.

Experimental infection of the intubated and previously sterile biliary tract of the dog with particles of the stools leads to a formation of urobilin from the bilirubin of the bile as it flows through the ducts. No urobilinuria occurs, however, unless temporary biliary obstruction is produced, or the liver parenchyma injured. Then urobilinuria develops, despite the fact that no bile is reaching the intestine and, by corollary, no urobilin being formed there. Cholangitic urobilinuria, as one may term the phenomenon just described, to distinguish it from the urobilinuria having origin in pigment absorbed from within the intestine, is far more pronounced in animals possessing a healthy gall bladder than in those with a pathological gall bladder or with one prevented from functioning by severance of the cystic duct. These facts suggest that there may be an active absorption of urobilin from the normal gall bladder. There can be no doubt that the pigment is absorbed from within the bile ducts. There is no evidence whatever to justify the belief that urobilin is ever formed through the action of liver parenchyma. There may conceivably be an intralobular formation of the pigment consequent upon the activity of bacteria within the liver tissue, though such a happening has yet to be demonstrated.

The existence of a gradient inherent to muscle cells of the biliary tract was examined in muscle cells isolated separately from the fundus of the gallbladder, cystic duct, and common bile duct of the dog. Muscle cells, measured in suspension or as single perfused cells, exhibited a proximal-to-distal gradient expressed by the magnitude of response and the sensitivity to hormonal cholecystokinin octapeptide and neural (acetylcholine and methionine-enkephalin) contractile agonists. Measurements in suspensions showed that cells from the fundus 1) were 7-40 times more sensitive to contractile agonists than cells from the cystic duct and 13-200 times more sensitive than cells from the common bile duct and 2) generated greater maximal contraction. The latter was expressed by the ratio of maximal responses (fundus: cystic duct cells, 1.90 +/- 0.12, P less than 0.001; fundus: common bile duct cells, 1.50 +/- 0.07 P less than 0.001), which was independent of sensitivity to agonists. Similar results were obtained in measurements on single cells with respect to relative sensitivity and to ratio of maximal responses (fundus: cystic duct cells, 1.80 +/- 0.08, P less than 0.001; fundus: common bile duct cells, 1.49 +/- 0.06, P less than 0.001). The ratio of responses to low concentrations of agonists was even higher (three- to fourfold), reflecting both the greater sensitivity and the greater contraction of muscle cells of the fundus. We conclude that a proximal-to-distal biliary gradient exists that is an inherent property of muscle cells from various regions of the biliary tract; the gradient would act to facilitate gallbladder emptying in response to hormonal and neural stimulation.

AbstractAnatomic anomalies of the biliary tract are not uncommon, but gallbladder and cystic duct agenesis is rare, with an incidence of 0.01% to 0.04% and a frequency of 0.016% at autopsy. It is usually asymptomatic and discovered incidentally. Although this congenital anomaly is infrequent, it may be encountered in clinical practice; thus, the surgeon should be aware of the associated problems. A correct preoperative diagnosis of this congenital anomaly is difficult to establish because of the nonspecific nature of the symptoms and the relative inaccuracy of the currently available diagnostic tests. Here we report a patient with a preoperative false diagnosis of cholelithiasis that was found on laparoscopy and open surgery to be agenesis of the gallbladder.

Objective: To assess the frequency of anatomical variations of the extra-hepatic biliary tract in patients undergoing laparoscopic cholecystectomy in Combined Military Hospital & Pak Emirates Military Hospital Rawalpindi. Study Design: Comparative cross-sectional study. Place and Duration of Study: Department of General Surgery, Combined Military Hospital & Pak Emirates Military Hospital, Rawalpindi, from Mar to Aug 2017. Methodology: A total of 136 patients of either gender with cholelithiasis of more than one month were included. Participants were distributed into equal number of groups for both hospitals by lottery method. All the participants had under gone laparoscopic cholecystectomy by consultant general surgeon or senior registrar under direct supervision. Structures mainly assessed for variations were gall bladder, cystic duct, common hepatic duct, supraduodenal part of common bile duct, cystic artery, and hepatic artery which were characteristically encountered during laparoscopy. Results: Overall Extra hepatic biliary variations were 136 (23%), at Combined Military Hospital 68 (16%) and Pak Emirates Military Hospital 68 (29.4%). Gall bladder anomaly was seen in 3% patients, cystic duct anomaly 4.4%, supraduodenal part of common bile duct anomaly 0.7%, cystic artery anomaly 11% and hepatic artery anomaly was seen in 3.6% patients (p>0.05). Conclusion:  Anatomic variations were found to be not uncommon in our set up. Thus, there is a need for doctors to continuously refresh knowledge of normal anatomy and the variants of biliary tract.

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.
