“…Therefore, it is important to focus on MSP for the diagnosis of SNADETs under magnifying endoscopy. Among the 11 reports summarized in Table 2, four found 33,34,39,42 multiple MSPs, and eight found 21,33,35,37,39,[41][42][43] irregularities or obscure MSPs as predictive of VCL C4/5 endoscopic findings. The results suggested that magnifying IEE is a useful procedure for the diagnosis of SNADETs atypia histologic grade.…”

Miura et al 41 recently reported the value of spraying acetic acid under M-NBI. According to their scheme, irregular MSPs are classified into three grades (iG1, iG2, and iG3); iG2 and iG3 are suggested to be signs of VCL C4/5 for protruding lesions and iG3 to be a sign of VCL C4/5 for depressed lesions.…”

In recent years, there have been significant advances in the endoscopic resection (ER) procedures of superficial nonampullary duodenal epithelial tumors (SNADETs). A preoperative endoscopic diagnosis is thus deemed necessary in determining the indication for subsequent ER. For the histologic and endoscopic diagnosis of SNADETs, understanding the mucin phenotype is inevitable. Recently, two diagnostic algorithms for the differential diagnosis of SNADETs from nonneoplastic lesions under magnifying endoscopy with narrow-band imaging have been proposed. In addition, various endoscopic approaches have been proposed to differentiate low-and high-grade adenomas/carcinomas, including white light endoscopy, magnifying image-enhanced endoscopy, and endocytoscopy. These methods, however, have not been standardized with respect to the classification of their findings and the validation of their diagnostic accuracy. Moreover, there are still concerns with respect to the histologic criteria required to establish a SNADETs diagnosis. Standardization in the histologic and endoscopic diagnosis of SNADETs is needed.

Purpose of review Adenomas are the most common benign lesions of the gastrointestinal tract. The current review aims to summarize recent literature regarding risk factors, natural history, diagnostic and staging technique, and management strategies for ampullary and nonampullary duodenal adenomas. Recent findings Recent studies identified several possible risks factors for duodenal adenomas (e.g., cholecystectomy, proton pump inhibitor use), although these associations require corroboration. Chromoendoscopy and endocystoscopy may offer accuracy comparable to biopsies in expert hands. Recent publications underscore the reduction in morbidity with endoscopic resection for lesions without signs of malignancy with submucosal invasion. Submucosal injection did not improve safety of endoscopic ampullectomy. Summary Surveillance may be a reasonable strategy for sub-centimeter ampullary adenomas occurring in familial adenomatous polyposis, as they carry a relatively low risk of malignancy. Endoscopic resection is the preferred strategy over surgery in patients without lesions suggestive of invasive malignancy. For nonampullary duodenal adenomas, several endoscopic resection techniques are available, each with their unique advantages and trade-offs. In patients who are not operative candidates but have intraductal extension, endoscopic ablation is an emerging option.

Background and AimOptical diagnosis of superficial nonampullary duodenal epithelial tumors using white‐light imaging (WLI) and/or narrow‐band imaging with magnifying endoscopy (NBI‐ME) is used to guide the treatment strategy and avoid biopsy‐induced fibrosis. However, the effectiveness of this approach has not been elucidated. We conducted a systematic review and meta‐analysis aiming to investigate the diagnostic yield between Vienna classification category 3 (VCL C3) and categories 4 or 5 (VCL C4/C5) using biopsy, WLI, NBI‐ME, and WLI + NBI‐ME.MethodsA literature search identified studies on the diagnosis of superficial nonampullary duodenal epithelial tumors using biopsy, WLI, or NBI‐ME. A bivariate random‐effects model was utilized to analyze the summary estimates of sensitivity and specificity, as well as the area under the summary receiver operating characteristic curves for diagnosing VCL C4/C5.ResultsUltimately, 13 studies were included in the meta‐analysis. For the diagnosis of VCL C4/C5, summary estimates of sensitivity, specificity, and area under the curve were for biopsy 47% (95% confidence interval: 37–58), 86% (79–91), and 0.745; for WLI 80% (65–89), 80% (70–87), and 0.859; for NBI‐ME were 72% (61–81), 76% (68–85), and 0.811; and for WLI + NBI‐ME 88% (67–96), 87% (51–98), and 0.929, respectively.ConclusionsWLI, NBI‐ME, and WLI + NBI‐ME showed high values for sensitivity and area under the curve. Biopsies can be replaced by WLI, NBI‐ME, and WLI + NBI‐ME for the preoperative diagnosis of superficial nonampullary duodenal epithelial tumors. However, further accumulation of research findings is needed.
