Abstract
BACKGROUND Data on endoscopic resection (ER) for superficial duodenal epithelial tumors (SDETs) are insufficient owing to their rarity. There are two main ER techniques for SDETs: endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD). In addition, modified EMR techniques, such as underwater EMR (UEMR) and cold polypectomy, are becoming popular. We conducted a large-scale retrospective multicenter study to clarify the detailed outcomes of duodenal ER. METHODS Patients with SDETs who underwent ER at 18 institutions from January 2008 to December 2018 were included. The rates of en bloc resection and delayed adverse events (AEs; defined as delayed bleeding or perforation) were analyzed. Local recurrence was analyzed using the Kaplan-Meier method. RESULTS In total, 3107 patients (including 1017 undergoing ESD) were included. En bloc resection rates were 79.1 %, 78.6 %, 86.8 %, and 94.8 %, and delayed AE rates were 0.5 %, 2.2 %, 2.8 %, and 6.8 % for cold polypectomy, UEMR, EMR and ESD, respectively. The delayed AE rate was significantly higher in the ESD group than in non-ESD groups for lesions < 19 mm (7.4 % vs. 1.9 %; P < 0.001), but not for lesions > 20 mm (6.1 % vs. 7.1 %; P = 0.64). The local recurrence rate was significantly lower in the ESD group than in the non-ESD groups (P < 0.001). Furthermore, for lesions > 30 mm, the cumulative local recurrence rate at 2 years was 22.6 % in the non-ESD groups compared with only 1.6 % in the ESD group (P < 0.001). CONCLUSIONS ER outcomes for SDETs were generally acceptable. ESD by highly experienced endoscopists might be an option for very large SDETs.

Endoscopic excision as a viable alternative to major resection for early duodenal cancers: A population-based cohort study. Int J Surg 2022; 101:106644. [PMID: 35500880 DOI: 10.1016/j.ijsu.2022.106644] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Revised: 03/29/2022] [Accepted: 04/26/2022] [Indexed: 12/21/2022]
Abstract
BACKGROUND Duodenal cancer presents an elusive therapeutic challenge for clinicians to treat because of its highly malignant behavior and anatomical complexity. Endoscopic excision has been administered to treat early-stage cancers of upper gastrointestinal tract, especially esophagus and stomach cancer. There is currently a scarcity of data regarding the application and efficacy of endoscopic resection for early duodenal cancer due to its rarity. This study aimed at exploring the prevalence and efficacy of endoscopic excision in treatment for early duodenal cancer in comparison with major surgery. METHODS This cohort study retrospectively collected patients with primary Tis/T1-N0-M0 duodenal cancer in the Surveillance, Epidemiology, and End Results database from 2004 to 2017. Prevalence of endoscopic excision in duodenal cancer treatment, overall survival (OS) and disease-specific survival (DSS) of patients who received different tumor-resection procedures were estimated. RESULTS A total of 1354 patients with Tis/T1-stage duodenal cancer were identified. Most patients (69.4%) underwent tumor resection as initial treatments. Among them, 65.7% underwent endoscopic excision, while 34.3% underwent major surgery. The multivariable Cox analyses revealed that endoscopic excision was associated with a significantly favorable OS (HR: 0.70; 95% CI: 0.52-0.95, p = 0.02) and DSS (HR: 0.32; 95% CI: 0.17-0.60, p < 0.001), compared to major surgery, for Tis/T1-stage cancer patients. In addition to cancer-related deaths (p < 0.001), endoscopic resection manifested significantly lower cumulative mortality rate of post-operative infectious diseases (p = 0.03). CONCLUSION Endoscopic resection currently accounted for approximately two-thirds of all procedures to resect Tis/T1-stage duodenal tumor. Endoscopic resection represents a viable therapeutic option in the management of Tis/T1-stage duodenal cancer for its oncological superiorities to major surgery and its capacity to reduce operative traumas and morbidities.

[PMID: 35310765 PMCID: PMC8828234 DOI: 10.1002/deo2.54] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/01/2021] [Revised: 08/10/2021] [Accepted: 08/11/2021] [Indexed: 11/29/2022]
Abstract
Although superficial non‐ampullary duodenal epithelial tumor (SNADET) was previously considered a rare disease, in recent years, the opportunities to detect and treat SNADET are increasing. Considering the high morbidity of pancreatoduodenectomy, endoscopic resection can be a treatment option that preserves the organs and contributes maintain patients’ quality of life. Endoscopic mucosal resection (EMR) is a standard treatment for relatively small lesions in gastrointestinal tracts, however, it is difficult because submucosal fibrosis frequently occurs due to the previous biopsy. Recently, some modified EMR techniques including underwater EMR (UEMR) and cold polypectomy (CP) have been proposed. In UEMR, the duodenal lumen is filled with water or saline and resected the targe lesion with a snare without injection into the submucosa. It would be a treatment option that could reduce candidates for ESD especially SNADET less than 20 mm. CP was reported as a safe and convenient means for SNADET. It would also be one of the standard treatments for diminutive lesions, though there remain some concerns on its resectability. ESD for SNADET is technically challenging, especially with an extremely high risk of adverse event (AE) with a reported bleeding rate of more than 20% and perforation rate up to about 40%. However, modified treatment techniques including the water pressure method and pocket creation method have been reported to potentially contribute to improving outcomes of ESD. Moreover, accumulated evidence shows closing the mucosal defect significantly reduces delayed adverse events after duodenal endoscopic treatments. Further studies are warranted to elucidate curative criteria, long‐term outcomes, and appropriate surveillance strategy.

Abstract
BACKGROUND An association between specific endoscopic findings and high-grade dysplasia/carcinoma in superficial nonampullary duodenal epithelial tumors ≤ 5 mm in size has not been reported. We sought to identify the endoscopic findings associated with high-grade dysplasia/carcinoma in patients with superficial nonampullary duodenal epithelial tumors ≤ 5 mm. METHODS We retrospectively assessed the data of 84 patients (88 lesions; low-grade dysplasia: n = 35, high-grade dysplasia/carcinoma: n = 53) with superficial nonampullary duodenal epithelial tumors who underwent initial treatment at a single center (from July 2009 to April 2021). All the patients had lesions sized ≤ 5 mm. We assumed that the endoscopic findings were independently associated with high-grade dysplasia/carcinoma and determined the accuracy, sensitivity, and specificity of a combination of independent factors for diagnosing high-grade dysplasia/carcinoma and low-grade dysplasia. RESULTS Multivariate logistic regression of significant factors in the univariate analysis revealed that lesions with depressed morphology (odds ratio: 23.9, 95% confidence interval: 2.8-204.2; p = 0.0037) and a reddish color (odds ratio: 175.7, 95% confidence interval: 11.4-2697.1; p = 0.0002) were independently associated with high-grade dysplasia/carcinoma. McNemar's test revealed that combining the macroscopic type and color provided significantly higher sensitivity for diagnosing high-grade dysplasia/carcinoma than color alone (98.1%, 95% confidence interval: 90.1-99.7 vs. 71.7%, 95% confidence interval: 58.4-82.0; p = 0.0002). CONCLUSIONS Reddish and depressed-type lesions before treatment were associated with high-grade dysplasia/carcinoma. Combining the macroscopic type and color can help detect high-grade dysplasia/carcinoma. These findings could help clinicians determine the best therapeutic strategy for patients with smaller (≤ 5 mm) superficial nonampullary duodenal epithelial tumors in clinical settings.

Abstract
BACKGROUND AND AIMS Duodenal endoscopic submucosal dissection (ESD) is considered technically challenging and has a high risk of adverse events. However, we recently made some progress with the ESD technique and device by introducing 2 features: a water pressure (WP) method and a second-generation ESD knife (DualKnife) with a water jet function (DualKnife J). The present study aimed to assess whether these changes improved the clinical outcomes of duodenal ESD. METHODS This was a retrospective observational study. Among all patients who underwent ESD for superficial duodenal epithelial tumors from June 2010 to December 2018, patients in whom a single expert performed the procedure were included in this study. Various factors, including the use of the WP method and ESD devices (DualKnife or DualKnife J) and the treatment phase (early, mid, and late), were analyzed to determine whether they were associated with intraprocedural perforation and procedure time. Treatment phase was assigned by dividing the study population equally into 3 subgroups according to the treatment phase. RESULTS The procedure time was significantly shorter, and the proportion of patients with intraprocedural perforations was the lowest in the late phase. Multivariate analysis of the use of the WP method revealed that it significantly decreased the intraprocedural perforation rate (odds ratio, 0.39; 95% confidence interval, 0.16-0.96), and analysis of the use of both the WP method (β coefficient, -0.40; P < .01) and the DualKnife J (β coefficient, -0.10; P = .032) revealed they were independently and negatively correlated with procedure time. CONCLUSION The present study reveals that the WP method significantly reduced the intraprocedural perforation rate and that both the WP method and the DualKnife J significantly shortened procedure times for duodenal ESD.

Abstract
BACKGROUND Endoscopic papillectomy (EP) is rapidly replacing traditional surgical resection and is a less invasive procedure for the treatment of duodenal papillary tumors in selected patients. With the expansion of indications, concerns regarding EP include not only technical difficulties, but also the risk of complications, especially delayed duodenal perforation. Delayed perforation after EP is a rare but fatal complication. Exposure of the artificial ulcer to bile and pancreatic juice is considered to be one of the causes of delayed perforation after EP. Draining bile and pancreatic juice away from the wound may help to prevent delayed perforation.
AIM To evaluate the feasibility and safety of placing overlength biliary and pancreatic stents after EP.
METHODS This is a single-center, retrospective study. Five patients with exposure or injury of the muscularis propria after EP were included. A 7-Fr overlength biliary stent and a 7-Fr overlength pancreatic stent, modified by an endoscopic nasobiliary drainage tube, were placed in the common bile duct and pancreatic duct, respectively, and the bile and pancreatic juice were drained to the proximal jejunum.
RESULTS EP and overlength stents placement were technically feasible in all five patients (63 ± 12 years), with an average operative time of 63.0 ± 5.6 min. Of the five lesions (median size 20 mm, range 15-35 mm), four achieved en bloc excision and curative resection. The final histopathological diagnoses of the endoscopic specimen were one tubular adenoma with high-grade dysplasia (HGD), one tubulovillous adenoma with low-grade dysplasia, one hamartomatous polyp with HGD, one poorly differentiated adenocarcinoma and one atypical juvenile polyposis with tubulovillous adenoma, HGD and field cancerization invading the muscularis mucosae and submucosa. There were no stent-related complications, but one papillectomy-related complication (mild acute pancreatitis) occurred without any episodes of bleeding, perforation, cholangitis or late-onset duct stenosis.
CONCLUSION For patients with exposure or injury of the muscularis propria after EP, the placement of overlength biliary and pancreatic stents is a feasible and useful technique to prevent delayed perforation.

Abstract
BACKGROUND Lesions involving the ampulla of Vater have traditionally been managed by surgical resection, albeit with high rates of morbidity and mortality. Endoscopic ampullectomy is increasingly recognized as an efficacious and safer treatment option. This study aims to evaluate the safety and efficacy of endoscopic ampullectomy for non-invasive ampullary lesions in a single tertiary referral center. METHODS Patients with non-invasive ampullary lesions, with or without familial adenomatous polyposis (FAP), were identified using pathology and endoscopy databases. The study included all patients who underwent the index ampullectomy between January 2007 and January 2017. Outcome parameters included accuracy of forceps biopsies, adverse events, success of endoscopic resection, and rate of recurrence. RESULTS A total of 53 patients underwent endoscopic ampullectomy over the 10-year period. Histological upstaging was seen in 37.8% of cases at ampullectomy compared to biopsy, including 5 cases (9.4%) of invasive adenocarcinoma. Adverse events occurred in 10 patients (18.9%) consisting of bleeding (11.3%), benign papillary stenosis (3.8%), acute pancreatitis (1.9%), and duodenal perforation (1.9%). Recurrence occurred in 32.7% over a median follow-up of 30 months (range 6-104 months), with the majority (18.4%) occurring at the first surveillance endoscopy. Nonetheless, 75% of recurrences were able to be cleared endoscopically. Endoscopic resection was successful in 91.1% of patients. CONCLUSIONS Endoscopic ampullectomy is an effective and safer therapeutic modality for non-invasive ampullary lesions, in addition to being a valuable diagnostic and staging tool. Nevertheless, careful patient selection and a commitment to endoscopic follow-up are of primary importance to achieve an optimal therapeutic outcome.

Abstract
Acute pancreatitis (AP) is a common adverse event (AE) of endoscopic papillectomy (EP). Prophylactic plastic pancreatic stent (PPS) placement appears to prevent AP. We evaluated factors associated with post-EP AP by a retrospective analysis of patients with tumors of the duodenal papilla who underwent EP from January 2008 to November 2016 at 2 tertiary care centers. Clinical, laboratory, endoscopic ultrasound parameters, and PPS placement were evaluated. Seventy-two patients underwent EP (37 men), with mean age of 60.3 (31–88) years. Mean main pancreatic duct (MPD) diameter was 0.44 (0.18–1.8) cm. Mean tumor size was 1.8 (0.5–9.6) cm. Tumors were staged as uT1N0, uT2N0, and uT1N1 in 87.5%, 11.1%, and 1.4%. Thirty-eight AEs occurred in 33 (45.8%) patients, with no mortality. Total bilirubin, tumor size, MPD diameter, and PPS placement had odds ratios (ORs) of 0.82, 0.14, 0.00, and 6.43 for AP. Multivariate analysis (PPS placement × MPD diameter) showed ORs of 4.62 (95%CI, 1.03–21.32; p = 0.049) and 0.000 (95%CI, 0.00–0.74; p = 0.042) for AP. In conclusion, patients with jaundice, large tumors, and dilated MPD seem less likely to have post-EP AP. PPS placement was associated with a higher risk of AP, which may question its use.

Abstract
Background and study aims Duodenal endoscopic submucosal dissection (ESD) is still considered technically challenging; however, few studies have objectively analyzed predictors of the technical difficulty. Therefore, the aim of the current study was to elucidate predictors of the technical difficulty of duodenal ESD. Patients and methods This was a retrospective observational study. From June 2010 to June 2017, a total of 174 consecutive patients with superficial duodenal epithelial neoplasia who underwent ESD were included in this study. We tried to identify predictors for technical difficulty of ESD by defining technical difficulty as either procedure time > 100 minutes or intraprocedural perforation. Moreover, we constructed a scoring system consisting of factors that were significant in the multivariate analysis. Results The proportion of patients with technical difficulty was 34.5 %. In the multivariate analysis, lesion location in flexural part [odds ratio (OR), 2.61; 95 % confidence interval (CI), 1.02 - 6.68], larger lesion size (> 40 mm) (OR, 5.26; 95% CI, 2.15 - 12.9), and occupied circumference > 50 % of the duodenum (OR, 5.80; 95 % CI, 1.83 - 18.4) were associated with technical difficulty. Conclusion A lesion location in flexural part, lesion size >40 mm and occupied circumference > 50 % were risk factors for technical difficulty of duodenal ESD.

Abstract
Background The management of ampullary lesions has shifted from surgical approach to endoscopic resection. Previous reports were limited by small numbers of patients and short follow-up. The aim of this study is to describe short- and long-term outcomes in a large cohort of patients undergoing endoscopic ampullectomy. Methods Retrospective study of endoscopic ampullectomies performed at a tertiary center from January 1999 to October 2016. Information recorded includes patient demographics, clinical outcomes, lesion pathology, procedural events, adverse events and follow-up data. Results Overall, 103 patients underwent endoscopic resection of ampullary tumours (mean age 62.3 ± 14.3 years, 50.5% female, mean lesion size 20.9 mm; 94.9% adenomas, with a majority of lesions exhibiting low-grade dysplasia (72.7%). Complete endoscopic resection was achieved in 82.5% at initial procedure. Final complete endoscopic resection was achieved in all patients with benign pathology on follow-up procedures. Final pathology showed that 11% had previously undiagnosed invasive carcinoma. Delayed postprocedure bleeding occurred in 21.4%, all of which were managed successfully at endoscopy. Acute pancreatitis complicated 15.5% of procedures (mild in 93.8%). Perforation occurred in 5.8%, all treated conservatively except for one patient requiring surgery. Piecemeal resection was associated with significantly higher recurrence compared to en-bloc resection (54.3% versus 26.2%, respectively, P = 0.012). All recurrences were treated endoscopically. Conclusion Endoscopic ampullectomy appears both safe and effective in managing patients with ampullary tumours in experienced hands. Most adverse events can be managed conservatively. Many patients develop recurrence during long-term follow-up but can be managed endoscopically. Recurrence rates may be reduced by performing initial en-bloc resection.

Clinical impact of closure of the mucosal defect after duodenal endoscopic submucosal dissection. Gastrointest Endosc 2019; 89:87-93.

Abstract
BACKGROUND AND AIMS Delayed adverse events (bleeding or perforation) are major concerns associated with duodenal endoscopic submucosal dissection (ESD). The aim of this study was to assess the efficacy of prophylactic closure of the mucosal defect after duodenal ESD. METHODS This is a retrospective study from a university hospital. One hundred sixty-eight patients (173 lesions) who underwent duodenal ESD between July 2010 and June 2017 were included in this study. The study participants were divided into 3 subgroups according to the degree of closure: complete group, incomplete group, and unclosed group. The proportion of delayed adverse events, maximum serum level of C-reactive protein (CRP), and total length of hospital stay were compared among these subgroups. Moreover, a multivariate logistic regression model was constructed to identify the risk factors for delayed adverse events. RESULTS The proportion of delayed adverse events in the complete group, incomplete group, and unclosed group were 1.7%, 25%, and 15.6%, respectively. The difference between the complete group and the other groups was significant (P < .01). The maximum serum CRP level was much lower (1.51 ± 2.18 mg/dL vs 6.28 ± 10.0 mg/dL, P < .01), and the length of hospital stay was significantly shorter in the complete group than in the incomplete/unclosed group (median [range] 5 [5-14] days vs 8 [4-59] days, P < .01). Multivariate analysis revealed that complete closure had a significant decrease in delayed adverse events (odds ratio [OR], 0.055; 95% confidence interval [CI], 0.01-0.29; P < .01), and a lesion located distal from the descending part showed a statistical tendency to an increase in delayed adverse events (OR, 4.48; 95% CI, 0.85-23.6; P = .08). CONCLUSION The present study revealed that complete closure of the mucosal defect after duodenal ESD significantly decreased the number of delayed adverse events and improved other outcomes.

Abstract
BACKGROUND AND AIMS Pancreaticoduodenectomy is an invasive procedure, and endoscopic resection (ER) is an alternative therapy. However, details regarding the outcomes of ER are unknown, especially for superficial duodenal epithelial neoplasia (SDET). The aim of this study was to elucidate the outcomes of ER for SDET and to compare EMR with endoscopic submucosal dissection (ESD). METHODS This was a retrospective observational study. From June 2010 to June 2017, 320 cases of endoscopically resected SDET (146 EMR-treated cases and 174 ESD-treated cases) were included in this study. We analyzed the proportions of en bloc resection, R0 resection, perforation, and bleeding as outcomes of ER and compared outcomes between the EMR and ESD groups. Next, we collected data on the features and clinical course of cases with adverse events. RESULTS The proportions of en bloc resection and R0 resection among all cases were 96.6% and 83.4%, respectively. In over 95% of cases, ESD achieved en bloc resection, regardless of lesion size. The incidences of perforation and bleeding were 8.8% and 3.4%, respectively, and the former was largely successfully managed by conservative treatment. The mortality rate was 0%, and all patients were discharged with a median hospital stay of 8.5 days (range, 4-52 days). Evaluation of the hospital stay duration according to lesion circumference revealed a significantly longer duration for lesions present on the medial wall than for other lesions (median 41 vs 7 days, P = .0331). CONCLUSION The present study revealed that ER achieved secure en bloc resection, with the treatment type (ESD or EMR) selected according to the lesion size. A lesion located on the medial wall was associated with worse outcomes, such as prolonged hospital stay after perforation.

Abstract
BACKGROUND - Conventional esophagogastroduodenoscopy is the best method for evaluation of the upper gastrointestinal tract, but it has limitations for the identification of the major duodenal papilla, even after the use of the straightening maneuver. Side-viewing duodenoscope is recommended for optimal examination of major duodenal papilla in patients at high risk for lesions in this region. OBJECTIVE To evaluate the use of the biopsy forceps during conventional esophagogastroduodenoscopy as an additional tool to the straightening maneuver, in the evaluation of the major duodenal papilla. METHODS A total of 671 patients were studied between 2013 and 2015, with active major duodenal papilla search in three endoscope steps: not straightened, straightened and use of the biopsy forceps after straightening. In all of them it was recorded whether: major duodenal papilla was fully visualized (position A), partially visualized (position B) or not visualized (position C). If major duodenal papilla was not fully visualized, patients continued to the next step. RESULTS A total of 341 were female (50.8%) with mean age of 49 years. Of the 671 patients, 324 (48.3%) major duodenal papilla was identified in position A, 112 (16.7%) in position B and 235 (35%) in position C. In the 347 patients who underwent the straightening maneuver, position A was found in 186 (53.6%), position B in 51 (14.7%) and position C in 110 (31.7%). Of the 161 remaining patients and after biopsy forceps use, position A was seen in 94 (58.4%), position B in 14 (8.7%) and position C in 53 (32.9%). The overall rate of complete visualization of major duodenal papilla was 90%. CONCLUSION The use of the biopsy forceps significantly increased the total major duodenal papilla visualization rate by 14%, reaching 604/671 (90%) of the patients (P<0.01) and it can be easily incorporated into the routine endoscopic examination of the upper gastrointestinal tract.

Abstract
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. This review will discuss the epidemiology of duodenal adenomas, their endoscopic detection and diagnosis, and techniques for safe and effective endoscopic resection of ampullary and non-ampullary lesions.

Abstract
BACKGROUND AND AIM It can be difficult to identify the cause of an enlarged ampulla of Vater (AOV). This study evaluated the accuracy of wire-guided intraduodenal ultrasonography (US) for the differential diagnosis of an enlarged AOV during endoscopic retrograde cholangiopancreatography (ERCP). PATIENTS AND METHODS Thirty-four patients with enlarged AOVs of unknown cause identified on imaging studies or endoscopic observations underwent wire-guided intraduodenal US using a catheter probe. RESULTS The final diagnoses were malignant or premalignant tumors in 10 patients (29.4%), stones in nine patients (26.5%), inflammation in 14 patients (41.2%), and cyst in one patient (2.9%). The overall diagnostic accuracy of intraduodenal US for enlarged AOVs was 91.2%. The diagnostic accuracies of stones, inflammation, and AOV tumors were 100.0%, 94.1%, and 91.1%, respectively. CONCLUSIONS Wire-guided intraduodenal US using a catheter probe is readily applicable during ERCP and may be useful in the differential diagnosis of enlarged ampullary lesions.

Abstract
The purpose of this two-part article is to review the cross-sectional anatomy of the ampulla and periampullary region, to propose novel and optimized MDCT and MRI techniques that allow accurate evaluation of the ampulla of Vater, and to summarize the cross-sectional imaging features of benign and malignant ampullary conditions. In this first part, we will review the normal anatomy of the ampullary region, provide suggestions on how to optimize evaluation of the ampullary region by MDCT and MRI, and review the imaging features of select epithelial neoplasms of the ampulla. Familiarity with the normal ampullary anatomy and the pathologic conditions involving the ampulla, as well as the use of optimized MDCT and MRI techniques, may improve the diagnostic accuracy of radiologists facing ampullary abnormalities.

Abstract
Historically, neoplasia of the duodenal papilla has been managed surgically, which may be associated with substantial morbidity and mortality. In the absence of invasive cancer, even lesions with extensive lateral duodenal wall involvement, or limited intraductal extension may be cured endoscopically with a superior safety profile. Endoscopic papillectomy is associated with greater risks of adverse events such as bleeding than resection elsewhere in the gastrointestinal tract. Additionally site-specific complications such as pancreatitis exist. A structured approach to lesion assessment, adherence to technical aspects of resection, endoscopic management of complications and post-resection surveillance is required. Advances have been made in all facets of endoscopic papillary resection since its introduction in the 1980s; extending the boundaries of endoscopic cure, optimizing outcomes and enhancing patient safety. These will be the focus of the present review.

Abstract
In the majority of cases, duodenal papillary tumors are adenomas or adenocarcinomas, but the endoscopy biopsy shows low accuracy to make the correct differentiation. Endoscopic ultrasonography and endoscopic retrograde cholangiopancreatography are important tools for the diagnosis, staging and management of ampullary lesions. Although the endoscopic papillectomy (EP) represent higher risk endoscopic interventions, it has successfully replaced surgical treatment for benign or malignant papillary tumors. The authors review the epidemiology and discuss the current evidence for the use of endoscopic procedures for resection, the selection of the patient and the preventive maneuvers that can minimize the probability of persistent or recurrent lesions and to avoid complications after the procedure. The accurate staging of ampullary tumors is important for selecting patients to EP or surgical treatment. Compared to surgery, EP is associated with lower morbidity and mortality, and seems to be a preferable modality of treatment for small benign ampullary tumors with no intraductal extension. The EP procedure, when performed by an experienced endoscopist, leads to successful eradication in up to 85% of patients with ampullary adenomas. EP is a safe and effective therapy and should be established as the first-line therapy for ampullary adenomas.

PATIENTS All 45 patients who had suspicious ampullary lesions (enlarged or protruded morphology) during duodenoscopy and underwent NBI between March 2010 and January 2011. INTERVENTIONS NBI. MAIN OUTCOME MEASUREMENTS NBI images were assessed for irregular villous arrangement, irregular villous size, ridge disappearance, demarcation with normal villi, and abnormal microvasculature. Histology of NBI-guided lesion biopsy specimens provided the final diagnoses. Agreement between NBI images and histologic findings was analyzed. RESULTS Of the 60 ampullary lesions, 11, 26, and 23 were adenocarcinomas, adenomas, and benign inflammatory diseases, respectively. Irregular villous arrangement, irregular villous size, ridge disappearance, demarcation with normal villi, and abnormal microvasculature were observed in 45%, 63%, 50%, 48%, and 58% of the lesions, respectively. Multivariate analysis revealed that irregular villous arrangement (odds ratio [OR] 15.76; 95% confidence interval [CI], 3.38-64.12; P < .001) and abnormal microvasculature (OR 86.63; 95% CI, 14.56-515.41; P < .001) were significant independent factors for identifying ampullary adenomas and adenocarcinoma. All tumors had at least one abnormal NBI feature. LIMITATIONS Retrospective design. CONCLUSION The NBI findings of irregular villous arrangement and/or abnormal microvasculature were useful for differentially diagnosing ampullary tumors. NBI may complement the accurate diagnosis of ampullary lesions by white-light imaging.

Abstract
Compared to tumors from other parts of the gastrointestinal tract, primary tumors of the duodenum are uncommon. Both benign tumors and malignancies are possible, although the majority are malignancies. The treatment of choice is surgical resection, mostly pancreaticoduodenectomy. With the development of endoscopy microsurgery and medical imaging technology, especially the advent of gastroduodenal fiberscopy, capsule endoscopy, endoscopic ultrasonography (EUS), endoscopic retrograde cholangio-pancreatography (ERCP) and laparoscopy, more duodenal neoplasms have been detected in recent years. Some advances have been achieved in the diagnosis and treatment of duodenal tumors. Endoscopic and segmental resections play a more and more important role in the management of duodenal tumors. In this paper, we describe the clinical features, pathological patterns, diagnosis and treatment of primary duodenal tumors.

Abstract
Endoscopic papillectomy (EP) is currently accepted as a viable alternative therapy to surgery in sporadic ampullary adenoma and has been reported to have high success and low recurrence rates. At present, the indications for EP are not yet fully established. The accepted criteria for EP include size (up to 5 cm), no evidence of intraductal growth, and no evidence of malignancy on endoscopic findings (ulceration, friability, and spontaneous bleeding). Endoscopic ultrasound (EUS) is the imaging modality of choice for local T staging in ampullary neoplasms. Data reported in the literature have revealed that linear EUS is superior to helical computed tomography in the preoperative assessment of tumor size, detection of regional nodal metastases and detection of major vascular invasion. Endoscopic ampullectomy is performed using a standard duodenoscope in a similar manner to snare polypectomy of a mucosal lesion. There is no standardization of the equipment or technique and broad EP methods are described. Endoscopic ampullectomy is considered a ‘‘high-risk’’ procedure due to complications. Complications of endoscopic papillectomy can be classified as early (pancreatitis, bleeding, perforation, and cholangitis) and late (papillary stenosis) complications. The appropriate use of stenting after ampullectomy may prevent post-procedural pancreatitis and papillary stenosis. Tumor recurrence of benign lesions occurs in up to 20% of patients and depends on tumor size, final histology, presence of intraductal tumor, coexisting familial adenomatous polyposis (FAP), and the expertise of the endoscopist. Recurrent lesions are usually benign and most can be retreated endoscopically.
