BACKGROUND:  Endoscopic resection of ampullary adenomas is a safe and effective alternative to surgical resection. A subgroup of patients have large laterally spreading lesions of the papilla Vateri (LSL-P), which are frequently managed surgically. Data on endoscopic resection of LSL-P are limited and long-term outcomes are unknown. The aim of this study was to compare the outcomes of endoscopic resection of LSL-P with those of standard ampullary adenomas. METHODS:  A retrospective analysis of a prospectively collected and maintained database was conducted...

BACKGROUND/AIMS: Endoscopic papillectomy (EP) has emerged as an alternative to surgery in the management of ampullary lesions. The aim of this study is to evaluate feasibility, efficacy, safety, outcome, and impact of EP in the management of benign ampullary lesions. MATERIALS AND METHODS: This is a multicenter, retrospective study of 44 patients who had EP of benign ampullary lesions. RESULTS: Over the 11-year period, 44 (55.7%) of 79 patients underwent EP for benign ampullary lesions...

Background and study aims:  To determine the clinical features associated with advanced duodenal and ampullary adenomas in familial adenomatous polyposis. Secondarily, we describe the prevalence and clinical significance of jejunal polyposis. Patients and methods:  This is a single center, prospective study of 62 patients with familial adenomatous polyposis. Duodenal polyposis was classified according to Spigelman and ampullary adenomas were identified. Patients with Spigelman III and IV duodenal polyposis underwent balloon assisted enteroscopy...

BACKGROUND: and study aims: Endobiliary dysplasia may persist after endoscopic papillectomy. Intraductal radiofrequency ablation (ID-RFA) is a potential alternative to complementary surgery. The aim of the study was to evaluate the efficacy and safety of ID-RFA for the treatment of adenomatous intraductal residue after endoscopic papillectomy. PATIENTS AND METHODS: A prospective open-label multicenter study included patients with histologically proven endobiliary adenoma remnant (ductal extent <20 mm), after endoscopic papillectomy for ampullary tumor...

We present here a case of transduodenal ampullectomy for an ampullary neoplasm coexisting with gastric and colon cancer. The patient was a 72-year-old man who was referred to our hospital with a positive fecal blood test. Colonoscopy revealed advanced cancer in the descending colon. As part of the preoperative examination, for the colonic cancer, upper gastrointestinal endoscopy was performed. Endoscopy showed a 2 cm elevated lesion(0'-II a type)with subserosalinfil tration on the small curvature side of the upper part of the stomach, and a 2 cm elevated lesion on the papilla of Vater...

OBJECTIVE: We investigate the efficiency of endoscopic mucosal resection (EMR) of non-ampullary sporadic duodenal adenomas (NASDA) in a retrospective analysis with long-term follow-up. METHODS: Consecutive patients undergoing EMR of NASDA between May 2002 and December 2016 were retrospectively identified from an electronic database. Endoscopic follow-up was scheduled after 3, 6 and 12 months for the first year, then yearly for up to five years. RESULTS: EMR of 75 NASDA was performed in 68 patients (56% en-bloc, 44% piecemeal)...

BACKGROUND AND AIMS: We aimed to investigate an association between clinicopathological features, including immunohistochemical mucin phenotypes, and magnifying chromoendoscopic findings with crystal violet staining (ME-CV) in non-ampullary duodenal epithelial tumors (NADETs). METHODS: A total of 55 patients with NADET were divided into 3 groups by mucin phenotype: intestinal, gastrointestinal, or gastric. ME-CV findings were classified into 4 patterns: convoluted, leaf-like, reticular/sulciolar, and pinecone...

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 AND AIMS: Sporadic non-ampullary duodenal adenomas (SNADAs), although uncommon, pose clinical challenges. Because SNADAs have malignant potential, endoscopic or surgical resection is generally recommended. EMR is increasingly used for resection of SNADAs, but large-scale data on natural history after EMR are scarce. In this study, we aimed to evaluate the clinical outcome of EMR for SNADAs and the natural history after EMR from a large, single-operator experience with dedicated follow-up...

BACKGROUND AND AIM: Endoscopic snare papillectomy (ESP) is an effective treatment for ampullary adenoma. Argon plasma coagulation (APC) is widely used as an additional method to control bleeding or ablate the residual tumor. However, the efficacy of this procedure has not yet been fully evaluated. This study aimed to evaluate the usefulness of APC as an additional method to ESP. METHODS: Patients who underwent ESP for ampullary adenoma between September 2005 and September 2015 were retrospectively reviewed...

Radiofrequency ablation (RFA) is a well-established treatment for several benign, premalignant, and malignant disorders. Although the role of RFA has been clearly defined, new indications for luminal and extraluminal applications of endoscopic RFA-directed therapies have emerged. RFA has recently produced promising results in patients with a variety of gastrointestinal and hepatopancreatobiliary pathologies. For example, endoscopic RFA has been used to treat patients with gastric antral vascular ectasia, chronic radiation proctitis, malignant biliary strictures, and ampullary adenomas with intraductal extension...

Yun Jung Nam, Byung Wook Kim, Joon Sung Kim, Gi Jun Kim
Sporadic non-ampullary duodenal adenoma is uncommon and found incidentally during endoscopic examinations. Brunner's gland hyperplasia is commonly encountered during endoscopic examinations. Adenomas arising from Brunner's gland hyperplasia originate from the glandular cells, and the surface epithelia are usually intact. Little has been reported on adenomas originating from the surface epithelium that overrides Brunner's gland hyperplasia. Here, we report a case of a sporadic non-ampullary duodenal adenoma overriding the cystic dilatation of Brunner's gland hyperplasia...

Adenomas of the ampulla of Vater are distinctly rare, representing <10% of periampullary neoplasms. Very few reports of the cytologic features of ampullary adenomas are present in literature, particularly in bile duct brushing samples. A case report and review of the literature is presented. The typical cytologic features of ampullary adenomas on cytologic preparations include tall, thin columnar cells with mildly hyperchromatic elongated nuclei and nuclear pseudostratification, in a relatively clean background...

REVIEW
Michael X Ma, Michael J Bourke
Duodenal adenomas are the most common type of polyp arising from the duodenum. These adenomas can occur within and outside of genetic syndromes, and are broadly classified as non-ampullary or ampullary depending on their location. All adenomas have malignant potential and are therefore appropriately treated by endoscopic resection. However, the unique anatomical properties of the duodenum, namely its relatively thin and vascular walls, narrow luminal diameter and relationship to the ampulla and its associated pancreatic and biliary drainage, pose an increased degree of complexity for any endoscopic interventions in this area...

Acute renal failure can be the result of acute renal cortical necrosis (RCN), which commonly occurs from complications occurring during pregnancy. RCN is rarely caused by medications, although tranexamic acid, which is used in patients with acute bleeding for its antifibrinolytic effects, reportedly causes acute RCN in rare cases. An 82-year-old woman experienced gastrointestinal bleeding after endoscopic papillectomy of an ampullary adenoma. The bleeding was controlled with tranexamic acid administration; however, 4 days later, her urine volume decreased and she developed pulmonary edema and dyspnea...

BACKGROUND: Endoscopic papillectomy (EP) is reported to be a relatively safe and reliable procedure for complete resection of ampullary neoplasms. The aim of this study was to evaluate the therapeutic outcomes and complications of EP for ampullary neoplasms. METHODS: A retrospective multicenter study was conducted with 5 participating centers from January 2007 to July 2014. A total of 104 patients who underwent EP for ampullary neoplasms were reviewed retrospectively...
