Abstract

The sonographic appearance and incidence of transverse common ducts were studied. A review of 118 intraoperative cholangiograms showed a transverse segment longer than 35 mm in 18% of the dilated extrahepatic ducts and in 6% of the normal caliber ducts. The causes of obstruction varied. When dilated, the transverse segment may be confused with the portal and splenic veins on a sonogram. An awareness of this anatomic variation can be helpful in locating an obstructing lesion of the extrahepatic bile duct.

Initial and long-term outcome after palliative surgical drainage of 269 patients with malignant biliary obstruction.

AIMS: This study aimed to analyse the current outcome after palliative surgical drainage of malignant biliary obstruction. METHOD: From 1992 to 2003, perioperative parameters and the incidence and indications of readmissions were analysed in 269 patients who underwent a palliative biliary bypass for periampullary carcinoma. RESULTS: Hospital mortality occurred in seven patients and median postoperative stay was 10 days. Anastomotic leakage occurred in three patients and intraabdominal haemorrhage in eight patients. Overall 75 patients experienced a complication. Nine patients underwent a relaparotomy during initial hospital admission. Overall, 142 patients were readmitted, 13 for indications related to the biliary bypass, 11 for surgery-related indications. Twenty-five patients were readmitted for radiochemotherapy, 112 for progressive disease and 23 for indications not related to the disease. Median survival was 7.5 months and the 3-year survival 3%. Survival was significantly lower in patients with metastases and in those who underwent elective bypass for gastric outlet obstruction. CONCLUSION: Current hospital mortality after palliative biliary bypass as well as readmission rates for complications related to the biliary bypass or surgical procedure are low. Surgical biliary bypass is a safe and effective palliative treatment for patients with malignant biliary obstruction.

Ectopic pancreas in the ampulla of vater with obstructive jaundice. A case report and review of literature.

Ectopic pancreas is an uncommon condition and is usually found in the gastrointestinal tract, such as stomach, duodenum and jejunum. However, ectopic pancreas in the ampulla of Vater is rare and its clinical presentations may be similar to periampullary cancer. It is difficult to diagnose preoperatively. We present such a case where the diagnosis was proven postoperatively. Our patient, a 51-year-old man, presented with epigastric pain, jaundice, weight loss and abnormal laboratory data. Imaging study, including abdominal sonography, abdominal computerized tomography with contrast and endoscopic retrograde cholangiopancreatography, showed a mass protruding into the ampulla of Vater. The mass was resected and histological examination revealed an ectopic pancreas. The patient presented with symptoms of periampullary tumor but the imaging study did not reveal an obvious lesion for us consider the possibility of ectopic pancreas. Surgical excision is indicated for symptomatic cases.

The Neo-Papilla: a new modification of porcine ex vivo simulators for ERCP training (with videos).

BACKGROUND: Computer simulators, live pigs, and ex vivo porcine simulators are used for training in ERCP. The location of the porcine biliary orifice in the proximal duodenum is dissimilar to human anatomy, making the endoscopy experience less realistic. In addition, in native porcine anatomy, the pancreatic duct enters the duodenum distal to the biliary orifice, limiting the teaching of pancreatic techniques and selective duct cannulation. OBJECTIVE: To overcome these limitations, we aimed to construct a Neo-Papilla that could be incorporated into an ex vivo model. DESIGN: We attached chicken heart tissue to the porcine duodenum, with integrated porcine arteries that resembled an artificial common bile duct and a pancreatic duct. SETTING: The simulator was presented and evaluated at 2 major GI endoscopy conferences. MAIN OUTCOME MEASUREMENTS: The feasibility and the realism of this prototype was tested by 9 recognized ERCP experts who rated this model in comparison to other teaching models for ERCP by recollection of prior experience. RESULTS: The Neo-Papilla was more prominent and more distally located than the native porcine papilla. The experts rated this modification superior to existing models in its usefulness as an educational tool. LIMITATIONS: Pilot study. CONCLUSIONS: We demonstrated the technical feasibility of a real-tissue Neo-Papilla modification of porcine ex vivo simulators, more closely approximating the natural anatomy. This new model should facilitate ERCP training. Formal validation studies are warranted.
