Multiple Carcinomata Associated with Anomalous Arrangement of the Biliary and Pancreatic Duct System

Two rare cases of multiple neoplasms occurring in association with anomalous arrangement of the pancreatobiliary duct system (PBD) are reported. Ultrasonography, computed tomography and endoscopic retrograde cholangiopancreatography revealed cholecystic tumor in the first case, and multiple choledochocholecystic tumors in the second case. In the first case, pancreatic tumor was discovered two years after cholecystectomy. In the second case, a pancreatic tumor was discovered incidentally in the removed pancreatic head after the operation. The histology of all of these biliary and pancreatic tumors revealed papillary adenocarcinoma in both patients, and additionally small pancreatic endocrine tumors were found in the first case. Postoperative prognosis was comfortably favorable in both patients. In a literature survey, two other cases of double carcinomata associated with anomalous PBD were found, in which the tumors showed the same histology of papillary adenocarcinoma and the postoperative prognoses were also good. These mutual clinicopathological features appear to suggest that this abnormal condition acts as a carcinogenetic risk factor in the pancreatic duct and the biliary duct system, and may finally cause multiple carcinomata in the PBD.

Anomalous arrangement of the pancreatobiliary ductal system in patients with a choledochal cyst

An anomalous arrangement of the pancreatobiliary ductal system is usually observed in patients with a congenital choledochal cyst and is represented by a long common channel distal to the pancreatobiliary junction. According to the angle of the pancreatobiliary junction, anomalous junctions can be classified into four groups: right angle, acute angle, complex union, and normal union (presented here in the order of their incidence). The right-angle type tends to have cystic dilatation of the choledochus, whereas the acute-angle type generally has cylindrical dilatation. However, the grade and length of the stenosis on the distal part of the choledochus tend to determine the type of choledochal cyst. Cystic dilatation is usually observed in patients with high-grade and long stenosis, whereas cylindrical dilatation is seen in those with low-grade and short stenosis. Patients with an acute angle junction seem to only suffer from abdominal pain, and those in the complex union group tend to have jaundice and an abdominal tumor. A high amylase level in the bile within the cyst is observed frequently. In patients with obstructive jaundice, however, the amylase level is usually not elevated, because pancreatic juice cannot enter the choledochus.

Surgical anatomy of the pancreatobiliary ductal system. Observations.

Introduction The continuing hospitalization of patients with postoperative traumatic defects of the pancreatobiliary ductal system, despite the improvements in surgical aids and skills in the past decade, has stimulated a rereview of this problem from a technical standpoint. In analysis of such cases in the literature 2 etiological factors are uniformly reiterated: (1) inadequate personal surgical skill and (2) unrecognized deviations from the anatomical normal. The authors defer correction of the former to the category of improvements in modern surgical education. However, it is believed that dissolution of the latter as an etiological agent of a critical postoperative complication can be effected by more thorough knowledge of the surgical anatomy of the region involved. To this end a detailed anatomical dissection of the complete pancreatobiliary ductal system was performed in 100 unselected autopsy specimens. The marked variation of anatomical relationships observed during this study has suggested that the term normal
