Ampulla of Vater* ; Duodenum ; Tuberculosis*

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.

Ampulla of Vater (AoV) is a small dilated duct less than 1.5 cm long, formed by the union of pancreatic duct and common bile duct. AoV has also anatomic layer of mucosa, sphincter of Oddi, perisphincteric or duodenal submucosa, and duodenal proper muscle, which corresponds to mucosa, muscularis mucosa, submucosa, and proper muscle layer of other gastrointestinal tract organs, respectively. Because of its small compact size and variation of anatomic structure, it is sometimes difficult to identify layering architecture of AoV. This anatomic difficulty may cause some problem in T classification of ampullary carcinoma (AC). The most confusing point in T classification is the vague definition of T2, "Tumor invades duodenal wall". It seems that duodenal wall includes duodenal mucosa, submucosa, and proper muscle layer. However there is no precise description or definition about duodenal wall that might lead personal variation in T classification of AC staging. We found that clinical course of AC with perisphincteric and/or duodenal submucosal invasion is more close to AC with T2 than T1. Although it is described as T1b according to T classification scheme of ordinary gastrointestinal tract cancer, we thought AC with T1b may have more high-grade malignant potential than those of other gastrointestinal (GI) tract malignancy. AC showed various clinicopatholgic findings that represent heterogeneous tumor groups within category of AC. Recently site-specific classification of AC was introduced, and it showed relatively well-categorized clinical prognosis. It may be reasonable to understand site-specific tumorigenesis in AC. The standard gross protocol is needed to evaluate pathologic T classification of AC. In conclusion, ampullary neoplasm is composed of various subtypes, which require a separate approach according to anatomic epicenter of ampullary neoplasm. Although submucosal invasion in AC was classified into pT1b, its' biologic behavior is more close to pT2.

Percutaneous transhepatic intervention for removal of common bile duct stones is introduced as a secondary choice of treatment in the high-risk patient. Through a percutaneous transhepatic biliary drainage catheter, a Dormia basket was inserted and the stone was entraped. Then the stone was crushed and fragments were passed spontaneously to the duodenum through the Ampulla of Vater. We experienced one case of successful treatment of a common bile duct stone using percutaneous transhepatic insertion of the Dormia basket.

Duodenum*

Cancer of the stomach is responsible for approximately 650,000 deaths globally each year and is probably second only to lung cancer worldwide as an overall cause of cancer-related mortality. Similar to the situation with most adenocarcinomas of the gastointestinal tract, carcinomas of the stomach can spread by local extension to adjacent normal structures and can develop lymphatic, peritoneal, and distant metastases. The tumor cells, can also permeate diffusely into the lymphatic plexus of the bowel, more often at the level of the upper duodenum hut sometimes down into the distal ileum and the large bowel. We report a case of lymphatic metastasis of gastric adenocarcinoma to the ampulla of Vater with review of the literature.

From November 1987 to December 1995, 76 patients with periampullary cancer underwent resectional surgery in the department of surgery, Kosin medical college. The object of this study was to assess the prognostic factors of the periampullary cancer after pancreaticoduodenectomy. The postoperative mortality rate was 11.8%. Significant morbidity occurred in 39.5% of the patients, early reoperation was required in 9.2% of these patients, and the mean hospital stay was 21.7 days. Univariate analysis on all patients revealed that the survival rate was significantly related to the size of the tumor (> or =3.0 cm 13%, <3.0 cm 41.4%; p<0.05), lymph node status (invasion 8.7%, no invasion 31.8%; p<0.05) and the age of the patient (>50 20.5%, < or =50 34.5%; p<0.05). The site was less significant(distal CBD 27%, ampulla of Vater 16.7%, pancreas 9%, duodenum 2%; p>0.05). These results indicated that patients with a tumor size lesser than 3cm, without lymph node involvement, and under the age of 50 had a long term survival rate.

Dieulafoy's lesion is an uncommon but important cause of massive upper gastrointestinal bleeding. The lesion usually occurs in the lesser curvature of the stomach within 6 cm of the gastroesophageal junction but extragastric locations of Dieulafoy's lesion are rare. In this study, diagnosis of Dieulafoy's lesion was frequently made by endoscopy instead of surgery. Hemostasis was achieved by endoscopic treatment in more than 90% of patients. We report the successful application of endoscopic hemoclipping for treatment of active bleeding from Dieulafoy's lesion in the ampulla of Vater of the duodenum.

Congenital duodenal web in adult life is an extremely rare condition, which results from an incomplete recanalization of the duodenum during early embryologic development. We report a case of congenital duodenal web in a 23-year-old man who complained of postprandial epigastric pain and fullness, as well as nausea since childhood. The plain abdomen showed a double-bubble sign. The UGI study showed a marked dilatation of the proximal duodenum and a delayed passage of barium into the third portion of the duodenum. Abdominal ultrasonography and CT revealed a marked dilatation of the proximal duodenum and a duodenal web with windsock deformity, which originated from the ampulla of Vater and extended to the third portion of the duodenum. A winsock web with a 0.9 cm eccentric aperture and a healed ulcer proximal to the ampulla of Vater were observed during a longitudinal duodenotomy. The web was excised circumferentially and the duodenum was closed transversely in a Heineke-Mikulicz fashion.

Objective: To evaluate the radiographic characteristics of the ampulla of Vater cancer. Subjects and Methods:The authors analyzed retrospectively the US(n=25) and CT(n=15) findings in 25 cases of ampulla of Vater cancer, with emphasis on the potential of CT & US in regand to the detectibility of the mass. ERCP(n=15) and hypotonic duodenography(n=5) were also evaluated for the configuration of obstructed duct. RESULTS: The tumor was detected on sonography in only 12 cases(48%) as a small, relatively well delinated mass with slighty low echogenicity to the pancreas. The tumor was shown by CT in 8 cases(53% ) as a well delinated mass protruding into the second portion of duodenal lumen with slightly low attenuation to the pancreas. CBD was dilated in 25 cases(100%), but pancreatic duct was dilated in 15 cases(60%). Obstructed end of CBD was nipple shaped in 7 cases(47%), clubbed in 3, flat in 3, and indistict in 2 by ERCP. Hypotonic duodenogram showed irregular filling defect in the medial wall of second portion of the duodenum in 5 cases (100%). CONCLUSION: Mas detection rate crsing US or CT were not high in ampulla of Vater cancer. Except for a CT finding of a small mass protruding into the regional duodenal lumen, other finclings were nonspecific. Therefore, additional studies or more afgressive approach should be attempted for a correct diagnosis.
