Endoscopic mucosal biopsies of the ampulla of Vater (AmpBx) are obtained to histologically assess for dysplasia or carcinoma. However, biopsy material is often scant and a host of factors can induce histologic changes that pose diagnostic challenges. We sought to investigate observer variability in interpretation of AmpBx and the impact clinical data may have on diagnostic interpretation. Thirty-one cases from institutional archives were selected, including 12 cases of reactive atypia (RA), 8 indefinite for dysplasia (ID), and 11 showing low-grade dysplasia (LGD)...

OBJECTIVES: To investigate immunohistochemical predictors for intestinal and pancreatobiliary types of adenocarcinoma of ampulla of Vater and identify clinicopathological characteristics associated with the histological types and patient survival. METHODS: Immunohistochemical markers included MUC1, MUC2, MUC5AC, CDX2, CK7, and CK20. The data were analyzed by univariate and multivariate methods. The two-step cluster method was used to determine the best immunohistochemical markers to discriminate the intestinal from the pancreatobiliary type...

The incidence of complex hepatobiliary injury secondary to blunt abdominal injuries varies between 3.4 and 5%. A 25-year old male patient underwent an urgent operation due to a motorcycle accident. During intraabdominal exploration, Grade 4 laceration was detected at the liver and bleeding was controlled through primary repair. In the postoperative seventh day, he was referred due to 1500 cc bile leakage from the drainage tube. During the operation, an extensive Kocher maneuver was done and the second part of duodenum was observed to be exposed to total avulsion from the head of the pancreas...

Introduction: Pancreatic ductal adenocarcinoma (PDAC) and ampulla of Vater adenocarcinomas (AVAC) are periampullary tumors. These tumors have overlapping symptoms and a common treatment, but present differences in their survival and biology. No recent studies in Mexico have been published that describe the clinicopathological characteristics of these tumors. Therefore, the aim of this study was to describe the clinicopathological characteristics of PDAC and AVAC in patients at a reference center in Mexico...

Cutaneous metastases from an adenocarcinoma of the Ampulla of Vater are very rare, with only a few cases previously reported. We present here an additional case in a 57-year-old woman who complained of a painful growth on her frontal scalp that she had noticed 4 months earlier. Her medical history included an ampullary adenocarcinoma, which was diagnosed 4 years ago, excised through a Whipple procedure, and treated using chemotherapy and radiotherapy. The scalp biopsy showed a dermal and epidermotropic well-differentiated glandular neoplasm with abundant neutrophils within the luminae of the tumoral glands...

A 71-year-old male presented to our institution with cholestatic hepatitis after having recently undergone upper endoscopy for treatment of gastrointestinal bleeding. Further investigation with endoscopic retrograde cholangiopancreatography revealed a hemostatic clip on the ampulla of Vater. After initial attempts at cannulation of the common bile duct were unsuccessful, biliary decompression was achieved by use of needle-knife fistulotomy. A common bile duct stent was placed and the liver function tests improved prior to discharge...

BACKGROUND: The invasive front of tumor can provide prognostic information in many cancers. We investigated the prognostic morphological factors at the invasive front including tumor differentiation (Difinv ) and tumor budding (Bud) in biliary tract cancer (BTC). METHODS: The resected specimen from the 299 BTC patients were examined. Intrahepatic cholangiocarcinoma, extrahepatic cholangiocarcinoma, gallbladder cancer, and ampulla of Vater cancer were found in 16%, 48%, 17%, and 19%, respectively...

BACKGROUND: Ampulla of Vater (AOV) carcinoma is a rare malignancy but has a relatively good prognosis. The aims of this study were to determine the clinicopathologic factors associated with survival and disease recurrence in patients with AOV cancer, focusing on the impact of preoperative endoscopic retrograde cholangiopancreatography (ERCP) and type of biliary drainage (endoscopic retrograde biliary drainage [ERBD] or percutaneous transhepatic biliary drainage [PTBD]). METHODS: We retrospectively reviewed the medical records of 80 patients who underwent curative resection for AOV cancer at a single institution between 1995 and 2015...

BACKGROUND: Bowel dilatation is a common adaptive mechanism after intestinal resection. The symptomatic dilated dysmotile duodenum is difficult to manage, since conventional bowel tailoring and lengthening techniques are potentially hazardous because of the anatomy of the duodenal blood supply, the proximity to the pancreas, and the risk of injury to the common bile duct. METHODS: A 2-month-old child with short bowel and a symptomatic massively dilated duodenum was treated with a Transverse Flap Duodenoplasty (TFD)...

AIM: To emphasize the significance of the platelet-to-lymphocyte ratio (PLR) in estimating the postoperative prognosis or survival measures in patients with carcinoma of the ampulla of Vater. METHODS: We retrospectively reviewed 82 patients, who underwent pancreaticoduodenectomy for ampullary carcinoma between July 2001 and April 2014. We investigated the predictive significance of the preoperative PLR for disease-free survival (DFS) or overall survival (OS). The possible correlations between the PLR and clinical or pathological features were also evaluated...

Renal cell carcinoma is the most common primary renal neoplasm in adults. Although renal cell carcinoma is known to spread to unusual sites, the ampulla of Vater is considered a rare site for metastasis. Here we present a case of renal cell carcinoma metastasized to the ampulla of Vater along with literature review. A 62-year-old Korean male had a history of hypertension and right-sided renal cell carcinoma diagnosed in September 2004, for which he underwent right radical nephrectomy in October 2004. The patient eventually underwent laparoscopic pylorus-preserving total pancreaticoduodenectomy in January 2017...

Marital status has been identified as a prognostic factor in multiple malignancies. In this study, we assessed the prognostic value of marital status in 24,035 patients from the Surveillance, Epidemiology, and End Results database diagnosed with biliary tract cancer (BTC) between 2004 and 2014. Widowed patients were more likely to be women, elderly (> 60 years), have gallbladder cancer, and have localized SEER Stage disease than all other patients. Marital status was identified as an independent prognostic factor in both univariate and multivariate analyses, and cause-specific survival (CSS) rates were higher in married patients than unmarried patients...

BACKGROUND: The American Joint Committee on Cancer recently proposed the eighth edition of cancer staging system. Validation studies are required to evaluate the prognostic stratification of ampulla of Vater cancer patients. METHODS: In the study, 369 operatively resected patients with ampullary cancers were grouped based on the eighth T (T1a, limited to sphincter of Oddi; T1b, invasion to duodenal submucosa; T2, invasion to duodenal proper muscle; T3a, invasion to pancreas ≤0...

Secondary tumours of the ampulla of Vater are rare. Underlying primary tumours, clinical presentation, macroscopic appearance, treatment strategies and outcome of secondary ampullary lesions have not been systematically analysed. The present case study reported a 57-year old patient with an ampullary metastasis from renal cancer and a literature review was performed in which a further 32 patients were included. The most common responsible primary tumours were malignant melanoma and renal clear cell carcinoma, followed by breast cancer...

Pancreatico-biliary (P-B) tumors arise from the pancreas, bile duct, and ampulla of Vater. Despite their close anatomical location, they have different etiology and biology. However, they uniformly share a poor prognosis, with no major improvements observed in overall survival over decades, even in the face of progress in diagnostic imaging and surgical techniques, and advances in systemic and loco-regional radiation therapies. To date, cytotoxic treatment has been associated with modest benefits in the advanced disease setting, and survival for patients with stage IV disease has not exceeded a year...

Mixed adenoneuroendocrine carcinoma (MANEC) is defined as a tumor that has morphologically recognizable both adenocarcinoma and neuroendocrine carcinoma components comprising at least 30% of either components. MANEC occurring in the ampulla of Vater is extremely rare, and only 16 cases have been reported in the English language literature. In the present report, we describe the first case of MANEC of the ampulla of Vater with immunocytochemical analyses. An 82-year-old Japanese male was incidentally found to have a tumorous lesion in the ampulla of Vater...

Background: Although some familial cancer syndromes include biliary tract cancers (BTCs; cancers of the gallbladder, intrahepatic and extrahepatic bile ducts, and ampulla of Vater), the few studies that have examined the relationships between family history of cancer (FHC) and BTCs have reported inconclusive findings. The objective of this study was to investigate the associations of FHC with risk of BTC in the Biliary Tract Cancers Pooling Project (BiTCaPP). Methods: We used Cox proportional hazards regressions models to estimate HRs and 95% confidence intervals for associations between FHC (any, first-degree, in female relative, in male relative, relative with gastrointestinal cancer, and relative with hormonally related cancer) and BTC risk by anatomic site within the biliary tract, adjusting for sex and race/ethnicity...

LESSONS LEARNED: Panitumumab has no clinical activity in metastatic RAS wild-type small bowel adenocarcinoma (SBA) and ampullary adenocarcinoma (AAC), possibly due to the foregut and midgut derivation of small bowel and ampulla.These results, along with findings from genomic characterization of SBA, suggest that SBA represents a unique intestinal malignancy and treatments should not be habitually extrapolated from colorectal cancer.Further studies evaluating the benefit of targeted therapies exclusively in SBA and AAC are warranted...
