Huisong Lee, Jin Young Park, Wooil Kwon, Jin Seok Heo, Dong Wook Choi, Seong Ho Choi
BACKGROUND: Transduodenal ampullectomy (TDA) is a less invasive procedure than pancreaticoduodenectomy (PD). However, the outcomes of TDA and PD have been compared rarely in early ampullary cancer. METHODS: From September 1994 to June 2013, the patients who underwent curative surgery for Tis or T1 ampulla of Vater neoplasm were identified. The patients were divided into two groups according to the types of surgery; TDA group and PD group. The patient characteristics and survival outcomes were retrospectively investigated between the two groups...

MULTICENTER STUDY
L Solaini, N B Jamieson, M Metcalfe, M Abu Hilal, Z Soonawalla, B R Davidson, C McKay, H M Kocher
BACKGROUND: Factors influencing long-term outcome after surgical resection for duodenal adenocarcinoma are unclear. METHODS: A prospectively created database was reviewed for patients undergoing surgery for duodenal adenocarcinoma in six UK hepatopancreaticobiliary centres from 2000 to 2013. Factors influencing overall survival and disease-free survival (DFS) were identified by regression analysis. RESULTS: Resection with curative intent was performed in 150 (84·3 per cent) of 178 patients...

BACKGROUND AND AIM: Gastrointestinal carcinoid tumors < 10 mm in diameter and limited to the submucosal layer demonstrate a low frequency of lymph node and distant metastasis, and are suitable for endoscopic treatment. The aim of this study was to assess the efficacy, safety, and long-term prognosis of endoscopic resections for the treatment of duodenal carcinoid tumors. METHODS: This study included a total of 41 duodenal carcinoid tumors in 38 patients between January 2006 and December 2011...

COMPARATIVE STUDY
Reese W Randle, Shuja Ahmed, Naeem A Newman, Clancy J Clark
BACKGROUND: Previous case series report that neuroendocrine tumors (NETs) of the ampulla of Vater have worse overall survival (OS) than NETs in the duodenum. We aimed to compare the OS of patients with ampullary NETs to patients with duodenal NETs. METHODS: This retrospective comparative cohort study used the Surveillance, Epidemiology, and End Results (SEER) registry from 1988 to 2009. OS was evaluated using Kaplan-Meier estimates and Cox proportional hazard regression...

REVIEW
Dermot O'Toole, Gianfranco Delle Fave, Robert T Jensen
Gastric neuroendocrine neoplasms (NENs) are increasing in frequency and have a varied spectrum with regard to histology, clinicopathologic background, stage, and prognosis. They are usually discovered incidentally, are for the most part benign and are associated with hypergastrinaemia (secondary either to chronic atrophic gastritis or rarely Zollinger-Ellison syndrome; types 1 and 2, respectively) or more rarely sporadic type 3. Applications of recent staging and grading systems - namely using Ki-67 proliferative indices - (from ENETS and WHO 2010) can be particularly helpful in further categorising these tumours...

AIM: To describe the specific characteristics of duodenal/perivaterian carcinoids and to analyze the diagnostic/therapeutic approach. MATERIAL AND METHODS: Eight patients were included in our study. Symptoms on admission included dyspepsia, upper gastrointestinal (GI) bleeding and anemia. All patients underwent upper GI endoscopy and gastrointestinal peptides (gastrin) and neuroendocrine markers (Chromogranin-A, CgA) measurement. Imaging studies were performed in all patients, including OCTREOSCAN, while in patients with ACs MRCP or ERCP was also performed, when necessary...

BACKGROUND: Carcinoid tumors of the duodenum are rare, and their natural history has not been defined. Consequently, there is no consensus on the optimal extent of surgical treatment. METHODS: The authors reviewed the records of all patients with primary carcinoid tumors of the duodenum treated at their institution from 1969 through 2004. Patients with primary periampullary tumors and gastrinomas were excluded. RESULTS: Twenty-four patients had a pathologic diagnosis of duodenal carcinoid tumor...

PURPOSE: To retrospectively evaluate the imaging features of duodenal carcinoids with clinical-pathologic comparison. MATERIALS AND METHODS: The institutional review board approved this study; informed consent was not required. The study was HIPAA compliant. The authors retrospectively reviewed the barium studies (n = 20), computed tomographic (CT) scans (n = 16), magnetic resonance (MR) images (n = 2), pathology reports (n = 33), gross pathology photographs (n = 15), and clinical data (n = 33) from 33 patients (16 men and 17 women; age range, 19-90 years; mean age, 52...
