1/32. Obstructive jaundice and acute cholangitis due to papillary stenosis.Papillary stenosis is characterized by fixed fibrosis leading to structural outflow obstruction and it is usually secondary to inflammation and fibrosis from the chronic passage of gallstones, episodes of acute pancreatitis, chronic pancreatitis, sclerosing cholangitis, peptic ulcer disease, and cholesterolosis. However, obstructive jaundice with or without acute cholangitis which leads the physician to suspect the presence of malignancy as a cause is a rare manifestation of papillary stenosis. We report here a case of papillary stenosis presenting with obstructive jaundice and acute cholangitis. The lesion was so difficult to exclude the presence of malignancy preoperatively and intraoperatively that a pylorus-preserving pancreaticoduodenectomy was performed. Histologic examination of the resected specimen revealed fibrosis, adenomatoid ductal hyperplasia, and mild chronic inflammation of the papilla of Vater and distal common bile duct.- - - - - - - - - - ranking = 1keywords = papilla (Clic here for more details about this article) |
2/32. gallbladder carcinoma with choledochoduodenal fistula: a case report with surgical treatment.A 79 year-old man was admitted to our hospital because of upper abdominal pain and nausea. A mobile tumor was palpable in the right upper abdomen. Abdominal ultrasonography, computed tomography and celiac angiography revealed a gallbladder tumor. Endoscopic retrograde cholangiopancreatography revealed a fistula 1.5 cm oral to the orifice of the papilla of Vater, dilatation of the common bile duct, and a filling defect in the gallbladder. Pancreatoduodenectomy associated with reconstruction using Imanaga's method was performed under a pre-operative diagnosis of gallbladder carcinoma with choledochoduodenal fistula. The gallbladder contained a tumor and two bilirubin stones impacted in the orifice of the duodenal papilla. Histological studies confirmed that the gallbladder tumor was a mucinous adenocarcinoma and had not infiltrated the bile duct. We speculated that choledochoduodenal fistula stimulated the development of cancer due to chronic irritation from pancreatic juice reflux.- - - - - - - - - - ranking = 0.28571428571429keywords = papilla (Clic here for more details about this article) |
3/32. Ampullary hamartoma: A rare cause of biliary obstruction.Tumors of the papilla of Vater are very rare. Despite advanced imaging techniques the distinction between benign and malignant tumors remains very difficult. Because most ampullary and periampullary tumors are malignant, primary management is surgical. Here we report the case of a 65-year-old man with biliary obstruction caused by an ampullary hamartoma simulating cancer. The correct diagnosis was not established until surgery.- - - - - - - - - - ranking = 0.14285714285714keywords = papilla (Clic here for more details about this article) |
4/32. Adenomyomatosis of the papilla of Vater: a case illustrating diagnostic difficulties.AIMS: To describe the extremely rare case of an adenomyoma of the papilla of Vater. CASE REPORT: A 42-year-old woman was hospitalized for epigastralgia and high fever. The clinical presentation and endoscopic, biochemical, and radiologic findings led to the diagnostic impression of a dysfunction of the papilla of Vater. The patient was treated successfully by laparotomy and duodenotomy, incorporating cholangiomanometry and cholangiography. Intraoperative frozen-section examination of a transduodenal papillectomy specimen led to the diagnosis of adenomyomatosis of the papilla. The patient is doing well 38 months postoperatively. CONCLUSION: Such a combined approach to intraoperative diagnosis was important to avoid excessive surgery for a benign periampullary disease.- - - - - - - - - - ranking = 1keywords = papilla (Clic here for more details about this article) |
5/32. Heterotopic pancreas in the ampulla of vater.We report a patient in whom heterotopic pancreatic tissue was found within the ampulla and treated by ampullectomy. Only 16 cases of pancreatic tissue located at the ampulla of vater have been reported in the literature and pancreaticoduodenectomy has been performed in more than half the cases because malignancy was suspected preoperatively, reflecting a rather aggressive surgical attitude. An accurate preoperative evaluation thus appears decisive to avoid unnecessary radical surgery. Endoscopic treatment of ampullary tumors is emerging as a viable alternative to surgical treatment. Local surgical excision is a reasonable option to endoscopic treatment. The possibility of heterotopic pancreatic tissue, though rare, should be included in the differential diagnosis of papillary tumors. Histologic confirmation (frozen or delayed) is mandatory before attempting such major surgery.- - - - - - - - - - ranking = 0.14285714285714keywords = papilla (Clic here for more details about this article) |
6/32. Needle-knife suprapapillary sphincterotomy avoids postprocedure pancreatitis in patients with sphincter of oddi dysfunction of biliary type II: a report of three cases.We report the cases of three patients who fulfilled the criteria for sphincter of oddi dysfunction of biliary type II and underwent needle-knife suprapapillary sphincterotomy. These patients presented with episodes of biliary-type pain after cholecystectomy and significant elevation of liver enzymes. ultrasonography and MRI cholangiography revealed dilatation of the common bile duct, without visible stones. The patients all underwent needle-knife suprapapillary sphincterotomy because free cannulation of the common bile duct could not be achieved. Needle-knife suprapapillary sphincterotomy enabled catheterization of the common bile duct. After clearing of the common bile duct with a balloon catheter, no stones, fragments of stones, or sludge were observed to exit from the sphincterotomy. None of our patients developed postprocedure pancreatitis. When needle-knife suprapillary sphincterotomy is performed by an experienced biliary endoscopist, it is a safe and effective procedure for patients with sphincter of Oddi dysfunction of biliary type II, who otherwise constitute a high-risk group for the development of postsphincterotomy pancreatitis.- - - - - - - - - - ranking = 1keywords = papilla (Clic here for more details about this article) |
7/32. Endoscopic ultrasound-guided bile duct access for rendezvous ERCP drainage in the setting of intradiverticular papilla.Cannulation of an intradiverticular papilla during endoscopic retrograde cholangiopancreatography (ERCP) can be challenging. We present here a technique for endoscopic ultrasound-guided puncture of the common bile duct followed by rendezvous ERCP for biliary drainage through the native intradiverticular papilla.- - - - - - - - - - ranking = 0.85714285714286keywords = papilla (Clic here for more details about this article) |
8/32. Parapapillary choledochoduodenal fistula associated with cholangiocarcinoma.Parapapillary choledochoduodenal fistula is a rare disorder. We herein report a case of parapapillary choledochoduodenal fistula associated with cholangiocarcinoma. A 61-year-old woman was admitted to our hospital for further examination of a liver tumor. She had no clinical symptoms, but computed tomography scans showed an irregularly contoured liver tumor which was histologically confirmed to be adenocarcinoma, by a needle biopsy examination. Duodenal fiberscopy revealed a fistula orifice 1.0 cm proximal to the orifice of the papilla of Vater, and endoscopic retrograde cholangiography through the fistula showed a communication to the common bile duct. Hypotonic duodenography demonstrated reflux of contrast material into the choledochoduodenal fistula. The bile sample collected from the common bile duct showed extremely high levels of pancreatic enzymes, including amylase, phospholipase-A2, and elastase-I. Furthermore, helicobacter dna was detected in bile by polymerase chain reaction (PCR) analysis. This experience suggests to us that parapapillary choledochoduodenal fistula may be a risk factor for biliary tract carcinoma, and surgical management is the treatment of choice for this rare condition, even when the patient has no significant clinical symptoms.- - - - - - - - - - ranking = 1.1428571428571keywords = papilla (Clic here for more details about this article) |
9/32. Endoscopic ultrasound guided therapy of benign and malignant biliary obstruction: a case series.OBJECTIVES: Endoscopic retrograde cholangiography is an established method for treatment of common bile duct stones as well as for palliation of patients with malignant pancreaticobiliary strictures. It may be unsuccessful in the presence of a complex peripapillary diverticulum, prior surgery, obstructing tumor, papillary stenosis, or impacted stones. Percutaneous transhepatic biliary drainage and surgery are alternative methods with a higher morbidity and mortality in these cases. Recently, endoscopic ultrasound (EUS) guided biliary stent placement has been described in patients with malignant biliary obstruction. We describe our experience with this method that was also used for the treatment of cholangiolithiasis for the first time. methods: The EUS guided transduodenal puncture of the common bile duct with stent placement was performed in 5 patients. In 2 of these patients, the stents were removed after several weeks and common bile duct stones were extracted. In another patient with gastrectomy, the left intrahepatic bile duct was punctured transjejunally and a metal stent was introduced transhepatically to bridge a distal common bile duct stenosis. RESULTS: Biliary decompression was successful in all 6 patients. No immediate complications occurred. One patient developed a subacute phlegmonous cholecystitis. CONCLUSIONS: Interventional EUS guided biliary drainage is a new technique that allows drainage of the biliary system in benign and malignant diseases when the bile duct is inaccessible by conventional ERCP.- - - - - - - - - - ranking = 0.28571428571429keywords = papilla (Clic here for more details about this article) |
10/32. Sphincter of Oddi response to caerulein after endoscopic sphincterotomy for papillary stenosis.Using a percutaneous transhepatic cholangioscopy (PTCS) catheter, sphincter of Oddi motility was measured in a patient with papillary stenosis secondary to bile duct stones. Prior to sphincterotomy, intramuscular injection of 20 micrograms caerulein did not inhibit pathological contraction waves of the sphincter of Oddi or relieve abdominal pain. Endoscopic sphincterotomy of the lower segment of the sphincter of Oddi resulted in recovery of the normal response to caerulein, i.e. relaxation of the sphincter of Oddi. This observation indicates that the pathological contraction and lack of relaxation to cholecystokinin in a patient with papillary stenosis is due to high common bile duct pressure. The measurement of motility of sphincter of Oddi via the PTCS route is useful in diagnosing motor disorders in the sphincter of Oddi and is helpful in deciding to perform endoscopic sphincterotomy.- - - - - - - - - - ranking = 0.85714285714286keywords = papilla (Clic here for more details about this article) |
