Duodenal neuroendocrine tumors are rare neoplasms arising from endocrine cells. Here we present a case of 32-year-old woman with Duodenal neuroendocrine tumors, report the imaging and contrast-enhanced Ultrasound (CEUS) features and review previous literatures of neuroendocrine tumors, which may be valuable for the differential diagnosis of duodenal neoplasms.

AbstractFor the management of diminutive duodenal neuroendocrine tumors (d-NETs), Harshit et al. have proposed – in the work accompanying this editorial – an interesting approach, the endoscopic banding without resection (BWR) technique. Given the risks associated with classic endoscopic resections and surgical procedures, and the likely favorable natural history of diminutive d-NETs, BWR may be an option for these selected patients with a very low risk of LN + and recurrence. However, a close follow-up (endoscopic, EUS and thoraco-abdominal CT scan) is then required to guarantee the safety of this policy.

Duodenal neuroendocrine tumors (NETs) are rare. Historically, when feasible a less aggressive surgical approach is considered. The aim of this study was to identify factors associated with prognosis and the necessity for more aggressive surgical procedures. All patients who underwent surgery for duodenal NETs between September 2005 and June 2014 were identified retrospectively. Data collected included clinical presentation, operative findings, and histopathological data. Eighteen patients underwent surgical management for duodenal NETs. Two patients underwent transduodenal excision (11%), two patients had partial duodenal resection (11%), two patients had antrectomy including 1st part of duodenum (D1) resection (33%), and eight underwent pancreaticoduodenectomy [PD (44%)]. On analysis, 2nd part of duodenum (D2) location was the most common site of duodenal NETs (n = 9, 50%). The odds of having a PD were 10 times higher when the lesion was in D2 location. The odds of having a positive lymph node are nine times higher when the lesion is in D2 region. The odds of having a positive lymph node are three times higher when lesion is greater than T1. D2 location of NETs is associated with higher odds of lymph node positivity and need for more extensive procedures like PD.

Abstract Background and study aims Regardless of size, duodenal neuroendocrine tumors (dNETs) should be considered potentially malignant. A complete resection without complications is essential to increase safety procedures. The aim of this review was to describe effectiveness and possible complications of endoscopic techniques resection for resectioning dNETs in patients with tumors ≤ 20 mm in diameter. Methods An electronic bibliographic search was conducted using MEDLINE (via PubMed), Embase, Cochrane Central, and Google Scholar virtual databases. The types of intervention were endoscopic mucosal resection alone (EMR) or with cap (EMR-C), with a ligation device (EMR-L), with previous elevation of the tumor (EMR-I) or with endoscopic submucosal dissection (ESD); argon plasm coagulation (APC), and polypectomy. The outcome measures adopted were presence of free margin associated with tumor resection, tumor recurrence, complications (bleeding and perforation), and length of the procedure. Results Ten publications were included with the result of 224 dNET resections. EMR alone and polypectomy resulted in the most significantly compromised margin. The most frequent complication was bleeding (n = 21), followed by perforation (n = 8). Recurrence occurred in 13 cases, the majority of those under EMR or EMR-I. Conclusions EMR-C or EMR-I should be preferred for resectioning of dNETs. Polypectomy should not be indicated for resection of dNETs due to the high occurrence of incomplete resections. EMR alone must be avoided due a higher frequency of compromised margin and recurrent surgery. ESD was associated with no recurrence, however, but an increased occurrence of bleeding and perforation.
