Annular pancreas and obstructive jaundice.

Annular pancreas is a rare abnormality which, in some cases, will be an incidental finding. Recently, two case reports have highlighted the possibility that annular pancreas is responsible for extrahepatic biliary obstruction in the absence of pancreatitis. We present a case of obstructive jaundice in which an annular pancreas was noted at both ERCP and CT scanning, but in which the cause of the obstruction was a carcinoma of the ampulla of Vater. Obstructive jaundice should not be attributed to an annular pancreas until the alternative differential diagnoses have been positively excluded.

The choledocho-pancreatico-ductal junction in infantile obstructive jaundice diseases.

A histopathological study on how the common bile duct and main pancreatic duct open into the duodenum was performed on autopsied cases of infantile obstructive jaundice diseases, and control cases. The so-called "common channel" formation type (Type III) was divided into two types; the junction of the common bile duct and the pancreatic duct was situated in the mucosal or submucosal layer of the duodenum in type IIIa and the junction below the propria muscularis of the duodenum in type IIIb. Type IIIb was identified in 17 out of 28 cases in congenital biliary atresia and in 2 cases of congenital choledochal cyst, while the control cases all belonged to type IIIa. In cases of type IIIb the well-developed sphincter muscle was located in the submucosal layer and it surrounded the common channel after joining of both ducts suggesting the possibility of free communication of both ducts. As the intraductal pressure of pancreatic duct is normally higher than that of the bile duct, reflux of pancreatic juice may occur into the bile duct. Abnormal choledocho-pancreaticoductal junction was suggested to be a pathogenic factor which causes infantile obstructive jaundice diseases. ACTA PATHOL. JPN. 30: 187 approximately 194, 1980.

Obstructive jaundice caused by a cholesterol polyp of the gallbladder: report of a case.

We present herein the case of a 34-year-old man in whom obstructive jaundice was found to be caused by an impacted detached cholesterol polyp. A cholecystectomy with exploration of the common bile duct was performed after ultrasonography showed cholesterol polyps and stones in the gallbladder. Intraoperative cholangioscopy demonstrated an impacted cholesterol polyp at the distal end of the common bile duct which appeared to be detached from the gallbladder. To our knowledge, this is the first report of an impacted detached cholesterol polyp causing obstructive jaundice.

[Evaluation of body fluid compartments and their relationship with water-electrolyte changes in obstructive jaundice].

BACKGROUND: The alteration of the mechanisms of water and sodium preservation may be an important factor in the development of acute postoperative renal failure in obstructive jaundice (OJ). Experimental OJ has been associated with a depletion of the extracellular volume and alteration of the mechanisms of regulation of hydrosaline metabolism. The aim of this study was to evaluate the distribution of the body volumes and the regulating hormones of hydrosaline metabolism in human OJ. PATIENTS AND METHOD: A prospective, clinical study evaluating 18 patients with OJ (9 females and 9 males) with a mean age of 69 +/- 8.9 years was performed. The plasma levels of antinatriuretic peptide (ANP), aldosterone and renin were determined. The body volumes were evaluated by tetrapolar bioimpedanciometry. The results of the patients with OJ were compared with a control group (CG) of 12 healthy subjects, matched for age and sex (6 females and 6 males with a mean age of 64.5 +/- 14 years). RESULTS: High ANP values were observed in 87.5% of the patients. The results of the hormonal studies compared with the CG were: ANP (117.33 +/- 37.7 vs 41.31 +/- 16.8 pg/ml; p < 0.001), aldosterone (185.68 +/- 82.1 vs 44.3 +/- 21.6 pg/ml; p < 0.001) and renine (57.18 +/- 69.9 vs 16.08 +/- 9.7 microU/ml; p < 0.05). Depletion of extracellular volume was found in 75% of the patients. CONCLUSIONS: Human obstructive jaundice is associated with an important alteration in the hormonal mechanisms of water and sodium regulation. This alteration is accompanied by a marked depletion of extracellular volume.

Evaluation of Pringle maneuver during liver resection in a rat model of surgical obstructive jaundice.

Temporary portal triad clamping (Pringle maneuver) during liver resection reduces intraoperative blood loss. A normal liver can safely tolerate normothermic ischemia for up to 60 min. However, its safety in patients with surgical obstructive jaundice (SOJ) is not known. Therefore, we investigated the effect of hepatic ischemia in an experimental rat model of SOJ created by ligating the bile duct. Four groups of rats were created: Group I (sham operation, 10 days later, liver resection); Group II (sham operation, 10 days later, liver resection with 5 min of hepatic ischemia); Group III (bile duct ligation, 10 days later, liver resection); and Group IV (bile duct ligation, 10 days later, liver resection with 5 min of hepatic ischemia). The ischemic injury was assessed by the survival of rats, liver tissue malondialdehyde and total glutathione (markers of free radical injury), serum alanine aminotransferase, aspartate aminotransferase, and liver histology. The results showed decreased survival (47.6% vs. 90% [p = .046]), increased liver tissue malondialdehyde (161 +/- 35 vs. 129 +/- 33 microg/gm liver tissue [p = .05]), and decreased liver tissue total glutathione (565 +/- 169 vs. 1075 +/- 276 nmol/gm liver tissue [p = .05]) in rats with SOJ subjected to hepatic ischemia when compared to nonjaundiced rats. The changes in serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase showed an increasing trend in the SOJ group but were not statistically significant. Ischemic changes in liver histology were seen more often in the SOJ group but were not statistically significant. These data suggest that temporary portal triad clamping in an experimental model of SOJ is detrimental to the outcome of liver resection.

Increased procoagulant activity of peripheral blood monocytes in human and experimental obstructive jaundice.

We studied the procoagulant activity of peripheral blood monocytes in 41 patients with severe obstructive jaundice and in 27 nonjaundiced control patients using a one-stage clotting assay. Mononuclear cells from jaundiced patients, tested immediately after isolation, expressed low levels of procoagulant activity, which were, however, significantly higher than in cells from controls (p less than 0.01). In addition, after incubation in short-term cultures with and without endotoxin, these cells generated more procoagulant activity than did the control ones (p less than 0.001). No significant difference in procoagulant activity was found between patients with and without malignancy in either group. The relief of biliary obstruction resulted in the reduction of both serum bilirubin levels and monocyte procoagulant activity. Endotoxin-induced monocyte procoagulant activity was about threefold higher in the jaundiced patients who died than in the survivors (p less than 0.001). In rabbits made icteric by bile duct ligation and separation (15 days), the endotoxin-induced monocyte procoagulant activity was markedly increased as compared with sham-operated animals (p less than 0.005). In all instances, procoagulant activity was identified as tissue factor. The increased capacity of mononuclear phagocytes to produce procoagulant activity might help explain the activation of blood coagulation in severe obstructive jaundice.

[Transhepatic biliary drainage as a method in the diagnosis and treatment of obstructive jaundice].

Percutaneous transhepatic biliary drainage was performed on eleven jaundiced patients, who had obstruction of the bile duct, in order to determine the exact site and nature of the obstruction and to alleviate the jaundice. In the present series, six patients were treated with external biliary drainage. Four of them received this treatment prior to radical surgery. In the remaining two cases the external drainage was a palliative procedure. In five patients, the drainage catheter was internalized through the obstructed bile duct (internal biliary drainage). One of these patients was subsequently treated with radical surgery. In two cases, the internal biliary drainage was palliative. In the two remaining cases, intraluminal selective irradiation was introduced via Iridium 192 flexible wires. Severe hemobilia occurred in one patient, who was successfully treated by lithotomy and "T" tube drainage. We conclude that the simplicity and low cost of these drainage procedures recommend them as extremely useful for the diagnosis and treatment of obstructive jaundiced patients.

Anomalous junction of the pancreaticobiliary duct accompanied by gallbladder cancer and obstructive jaundice in a patient with high serum and bile cytokine levels.

We report a case of anomalous junction of the pancreaticobiliary duct (AJPBD) associated with gallbladder cancer and obstructive jaundice in a patient with high serum and bile cytokine levels. The patient was a 63-year-old woman who complained of right hypochondralgia. Ultrasound, computed tomography, percutaneous transhepatic cholangiography, and endoscopic retrograde cholangio-pancreatatography revealed dilation of the bile ducts, an elevated lesion of the gallbladder, and AJPBD. She underwent percutaneous transhepatic cholangio-drainage (PTCD) for obstructive jaundice. However, the total bilirubin concentration remained high 7 days after PTCD. Her serum interleukin 6 level was 57,359 pg/ml before PTCD, and gradually decreased to 10 pg/ml after PTCD. Bile interleukin 6 level was 10 pg/ml before PTCD, 8997 pg/ ml 3 h after PTCD and gradually decreased there after. Serum and bile levels of tumor necrosis factor alpha and hepatocyte growth factor were high before and after PTCD. The patient underwent an extended cholecystectomy and resection of the extrahepatic bile duct. The resected specimen showed two elevated lesions of the gallbladder which, microscopically, revealed moderately differentiated tubular adenocarcinoma. These findings suggest that pre-existing inconspicuous inflammation of the biliary tract due to reflux of pancreatic juice is involved in elevation of serum and bile cytokines, and that cytokines may participate in gallbladder carcinogenesis associated with AJPBD.

[A case of advanced gastric cancer with obstructive jaundice that responded to TS-1/CPT-11 combination therapy after percutaneous transhepatic cholangio drainage].

TS-1/CPT-11 combination therapy was carried out in a case of advanced gastric cancer with liver and lymph node metastases and obstructive jaundice after percutaneous transhepatic cholangio drainage (PTCD). Regression of the primary carcinoma and reduction in size of metastases were observed. Grade 1 fatigue and grade 2 neutropenia were noted as adverse reactions to the treatment. TS-1/CPT-11 combination therapy was useful in this case of advanced gastric cancer with liver and lymph node metastases.

[Obstructive jaundice and bilirubin level].

A brief comparative description of normal and pathological bilirubin levels is followed in this paper by an account of findings recorded from 301 patients with obstructive jaundice. Particular reference is made to laws underlying preoperative rise, in the form of a logistic function, and postoperative decline of bilirubin, in the form of an exponential function. Average half-life, t/2, amounted to 7.5 days after successful surgery. Half-life was found to be affected by preoperative albumin levels but not by duration of obstructive jaundice, primary disease, surgical technique or other parameters.

[Clinical and experimental status of the metabolic aspects of obstructive jaundice].

In the paper, the authors gave an analysis of some aspects of the metabolism in 90 patients, treated surgically for extrahepatic bile tract diseases (in 43 of them obstructive jaundice being noted), and the results of 34 experiments on white rats are summarized. Based on the conducted studies on acid-base balance, electrolyte metabolism and oxidative phosphorylation in hepatic mitochondria in the experiment under various kinds of anesthesia, some recommendations are given for including sodium oxybutyrate in anesthesia, the latter possessing a positive metabolic effect in patients with obstructive jaundice.

Common bile duct papillary adenoma causing obstructive jaundice: case report and review of the literature.

Common bile duct (CBD) adenomas are rare tumors that often present in a fashion similar to their malignant counterparts. We report a case of a papillary CBD adenoma causing obstructive jaundice. We also present a review of the CBD adenomas found in the English literature through a Medline search (1970-2003). A 74-year-old female presented with a 10-day history of pruritus, progressive painless jaundice, acholic stools, bilirubinuria, and 10-lb weight loss. Abdominal exam showed no masses. Abdominal ultrasound (U/S) showed cholelithiasis without choledocholithiasis. Endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic U/S revealed a shelf-like stricture, 1.5 cm long and 0.9 cm in diameter, located in the distal CBD. At the time of biliary stent placement, fine-needle aspiration showed benign ductal epithelial cells in sheets and clusters. Abdominal CT scan showed a low attenuation 15 x 17 mm lesion in the head of the pancreas that abutted the superior mesenteric vein (SMV) but no metastatic lesions. We performed a standard pancreaticoduodenectomy (Whipple procedure). Final pathology showed a papillary adenoma without evidence of dysplasia in the distal common bile duct proximal to the ampulla of Vater. The incidence of these tumors and their potential for malignant degeneration is unknown. Pancreaticoduodenectomy is an effective means of treatment and cure for CBD adenoma.

Obstructive jaundice.

The case of a 67-year-old male patient affected by ingravescent obstructive jaundice, calcific choledocholithiasis and cardiopathic hypertension, is presented. On sonography, marked dilatation of intra- and extrahepatic bile ducts with a hyperechoic round neoformation was visualized. CT was performed to ascertain the nature of the lesion. However, it did not confirm the lithiasic nature of the stenosis. Sampling for ERCP was inadequate. Cholangiopancreatography was therefore necessary to establish a correct diagnosis and the subsequent therapeutic approach. Distal choledochal obstruction was evidenced, suspicious for lithiasis obstruction. A definitive diagnosis could not be established on exclusive imaging findings. Surgery was performed with the diagnosis of cholangiocarcinoma with lithiasis.

The effect of PARS inhibition on ileal histopathology, apoptosis and lipid peroxidation in LPS-induced obstructive jaundice.

In our experimental study, we investigated the protective effect of 3-aminobenzamide (3-AB), the poly (ADP-ribose) synthetase (PARS inhibitor), on the ileal histopathology and the apoptosis in lipopolysaccharide (LPS)-induced inflammation in rats with obstructive jaundice (OJ). We randomized 40 rats into five groups. Group 1: sham group; Group 2: OJ group; Group 3: OJ+LPS; Group 4: OJ+3-AB+LPS; Group 5: OJ+LPS+3-AB. At the fifth day; the rats were jaundiced. In Group 3; 10 mg kg(-1) LPS was injected intraperitoneally at the fifth day and then after 6h the rats were sacrificed. In Group 4; 10 mg kg(-1) 3-AB was administrated intraperitoneally at the fifth day and repeated daily for 3 days and at the eighth day, 10 mg kg(-1) LPS was injected intraperitoneally. In Group 5, 10 mg kg(-1) LPS was injected intraperitoneally at the fifth day and after 6h 10 mg kg(-1) 3-AB was administrated intraperitoneally and repeated daily for 3 days. At the eighth day, rats were sacrificed. Blood samples were taken for detection of serum MDA levels. Ileum samples were taken after relaparotomy for histopathological examination to evaluate the endotoxin-related intestinal injury and Caspase-3 apoptosis and for detection of tissue MDA and ATPase activities. There was marked destruction of villous and crypt epithelial cells and extensive apoptosis in Groups 3 and 5 in histopathological examination. In Group 4, the scores of intestinal mucosal damage and apoptotic cells were reduced significantly (P<0.05). On the other hand, the scores of intestinal mucosal damage and apoptotic cells were not improved in Group 5. After the administration of 3-AB (Group 4), serum and ileal MDA levels decreased, ileal ATPase increased as compared to Groups 1 and 2. Our study showed that 3-AB prevented the mucosal damage and apoptotic loss of intestinal epithelial cells significantly if it was administrated before LPS. However, 3-AB failed to prevent the mucosal damage and apoptotic loss of intestinal epithelial cells significantly if there was established endotoxemia in OJ.
