Most tumors affecting Vater's ampulla are adenocarcinomas, but a neuroendocrine carcinoma in the ampulla of Vater is extremely rare. The coexistence of these two tumors has been reported in only a few cases. Here, we report a rare case of a collision tumor of the ampulla of Vater with an adenocarcinoma and a large cell neuroendocrine carcinoma.

Study on 4 cases of malignant tumor of Vater’s ampulla operated at Viet-Duc Hospital and 1 case treated at University of Medicine and Pharmacy at Ho Chi Minh City between August 2003 and December 2004. Results: clinical sign is biliary obstruction jaundice. Gastroduodenoscopy with flexible tube found that papilla of Vater with the diameter lower than 3cm (histological finding: carcinomas), without metastasis to adjacent duodenum. Tumor invasion into head of pancreas and the lower of choledochous duct was determined by pancreatic and liver ultrasound, CT scanner or MRI examinations, in combination with intraoperative balance, immediate biopsy of lymph nodes in group 14 and group 8, sections of bile duct, pancreatic duct and duodenum in order to ensure the elimination of surgery. Initial outcomes showed that there wasn’t post-operative complication or death.

Duodenal duplication cysts are rare congenital malformations. Most symptomatic cases are diagnosed in children and usually present with obstructive findings or bleeding symptoms. Treatment traditionally involves surgical resection, which can be often difficult because of the close proximity of the cysts to the papilla and bilopancreatic confluence. Endoscopic therapy has been used as an alternative to open surgery in a few selected cases. We report a case with a duodenal duplication cyst containing a brown pigmented stone within the cystic lumen. He was visited because of sudden right upper quadrant abdominal pain. An abdominal computed tomography revealed the presence of a cyst with a stone, which was finally removed by endoscopic resection.

Small cell carcinoma in the ampulla of Vater is rare, and the concurrent occurrence of adenocarcinoma and small cell carcinoma is extremely rare. We report the case of a double primary tumor, adenocarcinoma and small cell carcinoma, in the ampulla of Vater.

For many years ERCP has been contraindicated in acute pancreatitis. The injection of contrast medium. which may cause hyperamylasemia and occasionally an attack of acute pancreatitis even in normal indivisuals, was allowed only two to three weeks after subsidence of symptoms. Gallstone disease is one of the most common etilogical factors in pancreatitis and migration or impaction of gallstone in the ampulla of Vater causes pancreatitis. (continue...)

BACKGROUND/AIMS: In recent years, endoscopic snare papillectomy has been performed to treat tumors of the ampulla of Vater. This procedure requires accurate preoperative evaluation. In this study, we diagnosed the focal extension of such tumors by using endoscopic ultrasonography (EUS) and intraductal ultrasonography (IDUS), and examined the indications for endoscopic snare papillectomy. METHODS: The subjects were 48 patients with a papillary tumor (13 patients, surgical resection; 35 patients, endoscopic snare papillectomy) who were evaluated preoperatively with EUS and IDUS. The tumor-node-metastasis classification was used for the endosonographic evaluation and pathological diagnosis of these tumors. RESULTS: The diagnostic accuracy of EUS was 97% for diagnosing adenomas and pTis tumors, 73% for pT1 tumors, 50% for pT2 tumors, and 50% for pT3-4 tumors, for an overall accuracy of 85% for T-staging. The diagnostic accuracy of IDUS was 94% for adenomas and pTis tumors, 73% for pT1 tumors, 50% for pT2 tumors, and 100% for pT3-4 tumors, for an overall accuracy of 80% for T-staging. CONCLUSIONS: EUS and IDUS are highly capable of evaluating tumors of the ampulla of Vater preoperatively. However, these techniques are not sufficient for evaluating the focal extension of carcinomas preoperatively. Currently, endoscopic snare papillectomy is adequate for treating adenomas and pTis tumors.

Endoscopic retrograde cholangiopancreatography (ERCP) in post-gastrectomy patients with Billroth II (BII) reconstruction and Roux-en-Y (RY) reconstruction presents a challenge to therapeutic endoscopists. Major difficulties, including intubation to the ampulla of Vater, selective cannulation, and ampullary intervention, must be overcome in these patients. Recent data have shown that device-assisted ERCP allows for high success rates in these patients because various devices are useful for overcoming major difficulties. Therefore, good knowledge of postoperative anatomy and various devices is mandatory before performing ERCP procedures for post-gastrectomy patients.

A 51-year-old man underwent diagnostic work-up for an abnormal-appearing ampulla of Vater. Three hours after biopsy of the ampulla, the patient presented with intense symptoms suggesting acute pancreatitis, which was later confirmed with laboratory and radiographic examinations. Other causes were excluded and the acute pancreatitis was considered a procedural complication. This is a rarely reported complication that must be taken into consideration when biopsies are performed in the ampulla of Vater.

Adenomyoma is a nonneoplastic lesion that can be found anywhere in the gastrointestinal tract, but it's rarely found in the ampulla of Vater. To the best of our knowledge, it is a benign lesion, but most cases are misdiagnosed as carcinoma or adenoma by a preoperative endoscopic or radiologic procedure, and this leads to unnecessarily extensive surgical resection. We report here on a case of ampulla of Vater adenomyoma that resulted in biliary and pancreatic duct dilatation. The tumor was diagnosed by endoscopic papillectomy.
