Investigations of the lymphatic routes using dye during operations and histological studies on the resected specimen of the pancreas and autopsied cases with pancreatic carcinoma have led to the conclusion that the surgery should be performed more extensively to improve the results and should consist of a complete lymphatic excision surrounding the celiac axis and the trunk of the superior mesenteric artery including dissection of the nerve plexus and wide retroperitoneal dissection surrounding the pancreas, upwards to the level of adrenal glands, and downwards to the level of iliac bifurcation. A translateral retroperitoneal approach was found to be the most useful and safe method for such extended resection in patients with pancreatic carcinoma. Our radical procedure for pancreatic carcinoma is described herein.

ABSTRACT— Two of three patients with infantile polycystic disease and all three patients with congenital hepatic fibrosis revealed multiple gross cystic dilatation of the intrahepatic biliary tree, referred to as Caroli's disease. All three patients with congenital hepatic fibrosis showed recurrent cholangitis related to coexisting Caroli's disease, and two of them died of sepsis following cholangitis. There were several common morphologic findings in the intrahepatic biliary tree of macroscopic and microscopic levels in infantile polycystic disease and congenital hepatic fibrosis with Caroli's disease: 1. irregular, non‐obstructive dilatation of the duct lumen; 2. bulbar protrusion of the duct wall into the lumen; and 3. bridge formation of the duct wall across the lumen. These ductal changes might be caused by a combination of uneven and disproportionate overgrowth of biliary epithelia and their supporting connective tissue. This pathogenetic mechanism might be operative along the entire intrahepatic biliary system in this disease group, and involvement of the smaller levels in early life might result in infantile polycystic disease and congenital hepatic fibrosis and simultaneous or possibly later involvement of the larger levels in Caroli's disease.

Candidiasis of the esophagus progressing to stricture formation in a 74-year-old male is reported. Esophageal candidiasis develops in the presence of various predisposing conditions such as long-standing administration of antibiotics or corticosteroids, and malignancy. The first endoscopic examination of this patient revealed unusual multiple black plaques in the esophagus. Despite intensive exploration, no predisposing factors were found. The stricture was progressive, despite the administration of adequate antifungal therapy, and its presence necessitated several attempts at dilatation. Case reports of esophageal candidiasis without underlying disease are very rare.

Three-dimensional-computed tomography (3D-CT) cholangiography is a 3D shaded surface display image of the biliary tract obtained by using helical CT after intravenous cholangiography or cholangiography per percutaneous transhepatic cholangio-drainage tube. We investigated whether 3D-CT cholangiography could provide a useful image, for preoperative examination in laparoscopic cholecystectomy. Sixty-five patients with biliary diseases were examined by 3D-CT cholangiography. Helical scanning was performed on a Proceed Accell (GE Medical Systems, Waukesha, WI, USA). Three-dimensional images were created using an independent workstation. A clear image of the common bile duct was obtained for all patients (100%) by 3D-CT cholangiography. The gallbladder was well visualized in 54 (93%) and the cystic duct was shown to be opacified in 55 (95%) of the 58 patients with a gallbladder. Thirty-one patients were diagnosed as having gallstones by 3D-CT cholangiography (sensitivity. 72.1%; specificity, 100%; accuracy, 79.3%), while 43 were diagnosed as having cholecystolithiasis by ultrasonography. The advantages of 3D-CT cholangiography were a low level of invasiveness, easily obtained images compared to those obtained with endoscopic retrograde cholangiography (ERC), good opacification, and provision of a three-dimensional understanding of the biliary system, especially of the cystic duct. When combined with ultrasonography and routine liver function tests, 3D-CT cholangiography was considered very useful for obtaining information before laparoscopic cholecystectomy. It allowed the omission of ERC in many patients who were considered to have no common bile duct stone, by employment of 3D-CT cholangiography.
