Endoscopic papillectomy for synchronous adenoma of the major and minor duodenal papilla. J Dig Dis 2024. [PMID: 38676317 DOI: 10.1111/1751-2980.13269] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 02/25/2024] [Accepted: 03/28/2024] [Indexed: 04/28/2024]
Abstract
OBJECTIVES Synchronous adenomas of the major and minor duodenal papilla are seldom reported. The aim of this study was to describe the characteristics of synchronous major and minor papilla adenomas and to evaluate the safety and efficacy of endoscopic papillectomy (EP) for the management of the disease. METHODS Consecutive patients who underwent endoscopy for synchronous major and minor papilla adenomas from January 1, 2013 to August 31, 2023 were analyzed retrospectively. Patients' characteristics, clinical manifestations, laboratory, imaging and endoscopic findings were collected. RESULTS The nine patients with synchronous major and minor papilla adenomas had an average age of 50.78 ± 10.70 years. The diameter of major and minor papilla adenomas was 12.11 ± 3.41 mm and 6.11 ± 1.05 mm, respectively. Most major papilla adenomas had R0 horizontal margins (n = 8), while R0 vertical margins were achieved in all patients. While minor papilla adenomas were resected with both R0 horizontal and vertical margins in all patients. Post-EP bleeding was observed in one patient, which was classified as mild. Post-EP hyperamylasemia and pancreatitis was observed in two and four patients, respectively; the latter consisted of three with mild pancreatitis and one with severe pancreatitis. No perforation was observed. The mean follow-up duration was 9.22 ± 5.99 months. Histologically confirmed recurrence at the resection site was detected in one patient at 3 months after the procedure. CONCLUSIONS Synchronous major and minor papilla adenomas may not be as rare as previously speculated. EP may be an effective and safe alternative modality for their management.

Endoscopic treatment of a patient with duodenal major papilla adenoma and ansa pancreatica. DEN OPEN 2024; 4:e240. [PMID: 37180358 PMCID: PMC10167413 DOI: 10.1002/deo2.240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Revised: 03/16/2023] [Accepted: 04/03/2023] [Indexed: 05/16/2023]
Abstract
A 35-year-old female who suffered from recurrent pancreatitis was admitted to our hospital. Her magnetic resonance cholangiopancreatography revealed ansa pancreatica. And during endoscopic retrograde cholangiopancreatography, a major duodenal papilla adenoma was identified. Hybrid endoscopic mucosal resection of this lesion was performed with pancreatic stent placement through the minor papilla to prevent recurrent pancreatitis. To our knowledge, this is the first report of a major papilla adenoma associated with ansa pancreatica. These minimally invasive endoscopic treatments solved a difficult clinical problem and avoided traumatic surgery.

The timing of recurrence after endoscopic papillectomy. Surg Endosc 2024; 38:688-696. [PMID: 38015261 DOI: 10.1007/s00464-023-10567-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Accepted: 10/23/2023] [Indexed: 11/29/2023]
Abstract
BACKGROUND Endoscopic papillectomy (EP) offers a safe and effective method for resection of ampullary adenomas. Data regarding the long-term resolution of adenoma following EP are limited. The aim of this study therefore was to examine the timing of recurrence after EP of ampullary adenomas. METHODS This was a single-center retrospective study including patients who received EP for ampullary adenomas from 8/2000 to 1/2018. Patients with confirmed complete eradication of adenoma were included in the recurrence analysis with recurrence defined as finding adenomatous histology after 1 negative surveillance endoscopy. Kaplan-Meier estimates were calculated to determine recurrence rates. RESULTS Of the 165 patients who underwent EP, 136 patients (mean age 61.9, 51.5% female) had adenomatous histology with a mean lesion size of 21.2 mm. A total of 124 (91.2%) achieved complete eradication with a follow-up of 345.8 person-years. Recurrence occurred in 20 (16.1%) patients at a mean of 3.2 (± 3) years (range 0.5-9.75 years) for a recurrence rate of 5.8 (95% CI 3.6-8.8) per 100 person-years. Nine (45%) recurrences occurred after the 1st 2 years of surveillance. Recurrence rate did not differ by baseline pathology [low-grade dysplasia: 5.2 (95% CI 3.0-9.0), high-grade dysplasia: 6.9 (95% CI 2.3-15.5), adenocarcinoma: 7.7 (95% CI 0.9-25.1)]. CONCLUSION Recurrence remains a significant concern after EP. Given the timing of recurrence, long surveillance periods may be necessary. Larger multicenter studies are needed, however, to determine appropriate surveillance intervals.

Efficacy of cap-assisted endoscopy for the visualization of the major duodenal papilla: a systematic review and meta-analysis. Gastrointest Endosc 2023; 98:1004-1008. [PMID: 37544335 DOI: 10.1016/j.gie.2023.07.050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Revised: 07/30/2023] [Accepted: 07/31/2023] [Indexed: 08/08/2023]
Abstract
BACKGROUND AND AIMS The current standard of practice is to use a duodenoscope for the evaluation of the major duodenal papilla (MDP). Recently, cap-assisted endoscopy (CAE), which uses a transparent cap at the tip of a standard front-viewing endoscope, has emerged as an alternative. METHODS A systematic literature search was performed in several databases from inception to January 2023 to identify studies evaluating the efficacy of CAE for the evaluation of the MDP. RESULTS Nine studies including 806 patients met our inclusion criteria. The pooled rate of technical success for CAE was 93.2% (95% confidence interval, 85.6-96.9; I2 = 84.6%). A subgroup analysis comparing CAE with a standard endoscope showed higher odds for the evaluation of the MDP with CAE (but not a duodenoscope, which was better than CAE) with an odds ratio of 57.294 (95% confidence interval, 17.767-184.755; I2 = 45.303%). CONCLUSIONS CAE offers a significant advantage with high rates of complete MDP evaluation compared with standard forward-viewing endoscopy. However, CAE is associated with lower rates of success when compared with side-viewing endoscopes.

Incidence and risk factors for recurrence of ampullary adenomas after endoscopic papillectomy: Comparative analysis of familial adenomatous polyposis and sporadic ampullary adenomas in an international multicenter cohort. Dig Endosc 2023. [PMID: 37985239 DOI: 10.1111/den.14725] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Accepted: 11/16/2023] [Indexed: 11/22/2023]
Abstract
OBJECTIVES Endoscopic papillectomy (EP) is a minimally invasive therapy for the management of ampullary adenomas (AA). We conducted this multicenter study to assess the incidence of and factors related to the recurrence of AA after EP in patients with familial adenomatous polyposis (FAP) compared to sporadic AA. METHODS We included patients who underwent EP for AA at 10 tertiary hospitals. Adenomatous tissue at the resection site at the time of surveillance endoscopies was considered recurrent disease. RESULTS In all, 257 patients, 100 (38.9%) with FAP and 157 (61%) patients with sporadic AA, were included. Over a median of 31 (range, 11-61) months, recurrence occurred in 48/100 (48%) of patients with FAP and 58/157 (36.9%) with sporadic AA (P = 0.07). Two (2%) FAP patients and 10 (6.3%) patients with sporadic AA underwent surgery for recurrence. On multivariable regression analysis, the recurrence in FAP was higher than in sporadic patients after the first year of follow-up. AA size (hazard ratio [HR] 1.03, 95% confidence interval [CI] 1.001, 1.056), periampullary extension (HR 2.5, 95% CI 1.5, 4.01), and biliary duct dilation (HR 2.04, 95% CI 1.2, 3.4) increased the risk, while en bloc resection (HR 0.6, 95% CI 0.41, 0.9) decreased the risk of recurrence. CONCLUSION Recurrence rates are high after EP. Most recurrences in sporadic patients occur within the first year of follow-up, but after the first year of follow-up in patients with FAP. Recurrences are higher with larger adenomas, biliary duct dilation, and periampullary extensions, and may be mitigated by en bloc resection. These factors should be considered in decision-making with the patients.

The Significance of Histopathological Findings on Clinical Outcomes in Endoscopic Papillectomy with Endocut. J Clin Med 2023; 12:6853. [PMID: 37959318 PMCID: PMC10648105 DOI: 10.3390/jcm12216853] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Revised: 10/21/2023] [Accepted: 10/29/2023] [Indexed: 11/15/2023] Open
Abstract
This study aimed to evaluate primary clinical outcomes in patients who underwent endoscopic papillectomy (EP) using the Endocut mode while examining the pathological characteristics of the margin of the resected specimen. To this end, 70 patients who underwent Endocut EP were included. Resection margins were classified according to pathological findings as "negative", "positive", or "uncertain (difficult pathological evaluation)". The effect of pathological resection margins on residual tumor recurrence rates was evaluated. The median follow-up was 47 months (range, 22-84). Eleven patients (15.7%) were diagnosed with residual tumors, ten of whom were diagnosed within 6 months after EP. The resection margins were pathologically negative in 27 patients, positive in 15, and uncertain in 28; residual tumors occurred in 5 patients (33.3%) in the positive group, 5 (17.9%) in the uncertain group, and 1 (3.7%) in the negative group. The patient in the negative group had familial adenomatous polyposis (FAP). Female sex, FAP, and uncertain or positive resection margins were significantly more common in residual patients (p = 0.009, 0.044, and 0.041, respectively). Pathological resection margins can be used to infer the residual tumor incidence, leading to early post-treatment of residual tumors.

Long-term follow-up of endoscopic papillectomy and the value of preventive pancreatic stent placement (with videos). Gastroenterol Rep (Oxf) 2023; 11:goad050. [PMID: 37867926 PMCID: PMC10585593 DOI: 10.1093/gastro/goad050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/26/2022] [Revised: 07/29/2023] [Accepted: 08/07/2023] [Indexed: 10/24/2023] Open
Abstract
Background Early-stage ampullary adenomas have only been reported in a small case series on endoscopic management. Hence, this study aimed to evaluate the long-term outcomes of early ampullary adenoma with endoscopic management and identify the risk factors for acute pancreatitis after endoscopic papillectomy (EP). Methods In this study, 115 patients who underwent EP at Changhai Hospital (Shanghai, China) between January 2012 and December 2018 were retrospectively analysed. Endoscopy was performed at 1, 3, 6, and 12 months after EP. Data were statistically analysed using the t-test or the Mann-Whitney U test. Results A total of 107 patients were included in this study and the follow-up period was 75 ± 43 months. The average age of the 107 patients was 54.6 years and the average tumor size was 17 mm. The average age of the patients (53.7 ± 10.7 years vs 55.2 ± 10.5 years, P = 0.482), minimum tumor size (13 vs 19 mm, P = 0.063), and complete resection rate (84.78% vs 85.25%, P = 0.947) did not differ significantly between the stent placement and non-stent placement groups. Post-EP acute pancreatitis rates in the non-stent placement and stent placement groups were 11.48% and 4.35%, respectively. The risk of post-EP acute pancreatitis was significantly associated with the preoperative carcinoembryonic antigen level in univariate analysis, but not in multivariate analysis. The risk of post-EP acute pancreatitis was not significantly associated with the placement of the pancreatic stent in either univariate or multivariate analysis. Moreover, delayed proximal pancreatic duct stenosis was not noted in either group during long-term follow-up. Conclusions EP is a satisfactory option for treating adenomas of the ampulla of the duodenum.

Abstract
INTRODUCTION There is an increasing interest in cold snare endoscopic mucosal resection (CS-EMR), and studies have shown its safety and efficacy for colonic polyps. This meta-analysis aims to assess the safety and efficacy of CS-EMR for the removal of duodenal adenomas. METHODS We conducted a comprehensive literature search of several databases, from inception through February 2023, for studies that addressed outcomes of CS-EMR for nonampullary duodenal adenomas. We used the random-effects model for the statistical analysis. The weighted pooled rates were used to summarize the technical success, polyp recurrence, bleeding, and perforation events. Cochran Q test and I2 statistics adjudicated heterogeneity. RESULTS Six studies were included in the analysis. In all, 178 duodenal polyps were resected using CS-EMR. The pooled rates were 95.8% (95% CI 89.1-98.5%, I2=21.5%) for technical success and 21.2% (95% CI 8.5-43.6%, I2=78%) for polyp recurrence. With regards to CS-EMR safety, the pooled rates were 4.2% (95% CI 1.6-10.5%, I2=12%) for immediate bleeding, 3.4% (95% CI 1.5-7.6%, I2=0%) for delayed bleeding, 2.8% (95% CI 1.1-6.7%, I2=0%) for perforation, and 2% (95% CL 0.5-7.5%, I2=0%) for post-polypectomy syndrome. Rates were not significantly different for large adenomas. Three studies reported data on CS-EMR and conventional EMR. Compared with conventional EMR, CS-EMR had lower odds of delayed bleeding, OR 0.11 (CI 0.02-0.62, P value 0.012, I2=0%). CONCLUSION Our findings suggest that CS-EMR is a safe and effective strategy for the resection of nonampullary duodenal adenomas, with an acceptable recurrence rate. Data from larger randomized controlled studies are needed to validate our findings.

Endoscopic Resection Techniques for Duodenal and Ampullary Adenomas. VIDEOGIE : AN OFFICIAL VIDEO JOURNAL OF THE AMERICAN SOCIETY FOR GASTROINTESTINAL ENDOSCOPY 2023; 8:330-335.

Abstract
Background and Aims Duodenal polyps have a reported incidence of 0.3% to 4.6%. Sporadic, nonampullary duodenal adenomas (SNDAs) comprise less than 10% of all duodenal polyps, and ampullary adenomas are even less common. Nonetheless, the incidence continues to rise because of widespread endoscopy use. Duodenal polyps with villous features or those that are larger than 10 mm may raise concern for malignancy and require removal. We demonstrate endoscopic resection of SNDAs and ampullary adenomas using some of our preferred techniques. Methods The duodenum has several components that can make EMR of duodenal polyps technically challenging. Not only does the duodenum have a thin muscle layer, but it is also highly mobile and vascular, which may explain higher rates of perforation and bleeding of duodenal EMR reported in the literature compared with colon EMR. A standard adult gastroscope with a distal cap is commonly used for duodenal EMRs. Based on the location, however, side-viewing duodenoscopes or pediatric colonoscopes may be used. To prepare for EMR, a submucosal injection is performed for an adequate lift. The polyp is then resected via stiff monofilament snares and subsequently closed with hemostatic clips if feasible. The ampullectomy technique differs slightly from duodenal EMRs and carries the additional risk of pancreatitis. Submucosal injection in the ampulla may not lift well; thus, its utility is debatable. Biliary sphincterotomy should be performed, and based on endoscopist preference, the pancreatic duct (PD) guidewire can be left during resection to maintain access. After resection, a PD stent is placed to minimize pancreatitis risk. Results The video shows the aforementioned duodenal EMR techniques. Two clips of ampullectomy are also shown in the video. Conclusions A few common techniques used to perform duodenal EMR and ampullectomy are highlighted in the video. It is important to understand and manage adverse events associated with these procedures and to have established surveillance plans.

Abstract
Background/Aims There are limitations in treating ampullary adenomas with intraductal extension using conventional endoscopic modalities. Endoscopic intraductal radiofrequency ablation (ID-RFA) may be useful for treating intraductal (common bile duct [CBD] and/or pancreatic duct [PD]) extensions of ampullary adenomas, but long-term data are lacking. We thus evaluated the long-term outcomes of endoscopic ID-RFA for managing ampullary adenomas with intraductal extension. Methods Prospectively collected endoscopic ID-RFA database at Asan Medical Center was reviewed to identify consecutive patients with ampullary adenoma who underwent ID-RFA for intraductal extension between January 2018 and August 2021. Technical success, short-term and long-term clinical success, and adverse events were evaluated. Results A total of 29 patients (14 CBD, 1 PD, and 14 CBD and PD) were analyzed. All patients had undergone endoscopic snare papillectomy prior to ID-RFA. A median of one session of ID-RFA (range, 1 to 3) for residual or relapsed intraductal extension of ampullary adenoma were successfully performed (technical success=100%). Both biliary and pancreatic stenting were routinely performed after ID-RFA to prevent ductal stricture. After a median follow-up of 776 days (interquartile range, 470 to 984 days), the short-term and long-term clinical success rates were 93% and 76%, respectively. Seven patients experienced procedural adverse events and three patients developed ductal strictures. Conclusions Endoscopic ID-RFA showed good long-term outcomes in treating residual or relapsed ampullary adenomas with intraductal extension. Repeated ID-RFA may be considered as an option for managing recurrence. Further studies are needed to standardize the procedure.

Abstract
BACKGROUND AND AIMS Ampullary adenomas are treated both surgically and endoscopically, however, data comparing both techniques are lacking. We aimed to compare long-term recurrence of benign sporadic adenomas after endoscopic (EA) and surgical ampullectomy (SA). METHODS A comprehensive literature search of multiple databases (until December 29, 2020) was performed to identify studies reporting outcomes of EA or SA of benign sporadic ampullary adenomas. The outcome was recurrence rate at 1 year, 2-year, 3 year and 5 years after EA and SA. RESULTS A total of 39 studies with 1753 patients (1468 EA [age 61.1 ± 4.0 years, size 16.1 ± 4.0 mm], 285 SA [mean age 61.6 ± 4.48 years, size 22.7 ± 5.4 mm]) were included in the analysis. At year 1, pooled recurrence rate of EA was 13.0% (95% confidence interval [CI] 10.5-15.9], I2 = 31%) as compared to SA 14.1% (95% CI 9.5-20.3 I2 = 15.8%) (p = 0.82). Two (12.5%, [95% CI, 8.9-17.2] vs. 14.3 [95% CI, 9.1-21.6], p = 0.63), three (13.3%, [95% CI, 7.3-21.6] vs. 12.9 [95% CI, 7.3-21.6], p = 0.94) and 5 years (15.7%, [95% CI, 7.8-29.1] vs. 17.6% [95% CI, 6.2-40.8], p = 0.85) recurrence rate were comparable after EA and SA. On meta-regression, age, size of lesion or enbloc and complete resection were not significant predictors of recurrence. CONCLUSION EA and SA of sporadic adenomas have similar recurrence rates at 1, 2, 3 and 5 years of follow up.

Abstract
BACKGROUND Conventional endoscopic papillectomy (ESP) for ampullary adenoma is performed as a hybrid endoscopy and fluoroscopy guided procedure. In this study, we report our preliminary experience of non-radiation ESP. METHODS The present method includes endoscopic snare resection, non-radiation endoscopic biliary and pancreatic stenting and endoclipping. Data from ten patients who underwent non-radiation ESP due to ampullary adenoma were collected. Procedure details, adverse events and follow-up were analyzed. RESULTS Complete resection was accomplished in all patients, with en bloc resection and piecemeal resection in nine and one patient(s), respectively. Both biliary and pancreatic stenting and biliary stenting alone were achieved in eight and two patients, respectively. Endoclipping was performed in all patients. Hyperleukocytosis and hyperamylasemia occurred in two and one patient(s), respectively. No other complications occurred. No lesion residual or recurrence occurred during follow-up. CONCLUSIONS Radiation-free ESP can be technically feasible and safely executed by experienced endoscopists. Our study provides a novel strategy for endoscopic resection of major papilla adenoma.

Abstract
BACKGROUND Evidence of endoscopic papillectomy (EP) for ampullar adenoma with high-grade dysplasia (HGD) or adenocarcinoma is insufficient. Here we investigated the long-term outcomes of the advanced ampullary tumors treated by EP with careful surveillance comparing to subsequent surgery after EP. METHODS Patients treated with EP for ampullary adenoma with HGD or adenocarcinoma from the multi-center retrospective Korean cohort of ampulla of Vater tumor were categorized into EP alone versus EP with subsequent surgery groups. The overall survival (OS) and recurrence-free survival (RFS) were analyzed for unmatched and matched cohorts using propensity score with nearest neighbor method. RESULTS During a median 43.3 months of follow-up, 5-year OS was not significantly different between the EP alone and EP surgery groups (91.9% vs. 82.3%, P = 0.443 for unmatched cohort; 89.2% vs. 82.3%, P = 0.861 for matched cohort, respectively). Furthermore, 5-year RFS was not significantly different between the two groups (82.1% vs. 86.7%, P = 0.520 for unmatched cohort; 66.1% vs. 86.7%, P = 0.052 for matched cohort, respectively). However, the patients with positive both (lateral and deep) margins showed significantly poorer survival outcomes than those with negative margins within the EP alone group (P = 0.007). CONCLUSION EP alone with careful surveillance showed comparable survival outcomes to those of EP with subsequent surgery for ampullar HGD or adenocarcinoma. Resection margin status could be a parameter to determine whether to perform subsequent radical surgery after EP.

Abstract
Upper gastrointestinal (GI) malignancy is a leading cause of cancer-related morbidity and mortality. Upper endoscopy has an established role in diagnosing and staging upper GI cancers, screening for pre-malignant lesions, and providing palliation in cases of advanced malignancy. New advances in endoscopic techniques and technology have improved diagnostic accuracy and increased the therapeutic potential of upper endoscopy. We aim to describe the different types of endoscopic technology used in cancer diagnosis, summarize the current guidelines for endoscopic diagnosis and treatment of malignant and pre-malignant lesions, and explore new potential roles for endoscopy in cancer therapy.

Endoscopic Papillectomy for Ampullary Tumors. THE KOREAN JOURNAL OF HELICOBACTER AND UPPER GASTROINTESTINAL RESEARCH 2022.

Abstract
Ampullary tumors originate from the ampulla of Vater and are often discovered incidentally during an upper endoscopy. These tumors usually occur sporadically and may be benign or malignant in nature. Tumor growth clinically presents with cholestasis, pancreatitis, and bleeding. Patients with ampullary adenomas are often asymptomatic; however, removal of these lesions is recommended in view of their malignant potential. Following advances in endoscopic techniques and the accumulation of experience, considering high recurrence, mortality, and morbidity rates associated with surgery, endoscopic papillectomy may be useful as first-line treatment for adenomatous lesions with ambiguous malignant changes or focal intraepithelial carcinoma. Although it is relatively safe and easy to perform, the operation is a high-level procedure that may be associated with serious complications. It should be performed by an experienced endoscopist at a well-equipped hospital/center with emergency facilities and support personnel. Accurate resection is associated with high treatment success rates. Most complications are mild and can be treated medically. Pancreatitis is the most common complication, and pancreatic duct stenting is useful for prophylaxis. Recurrence may occur, and is more frequently observed during segmental resection; therefore, close periodic follow-up is essential. Although there are no unified indications or guidelines for endoscopic papillectomy, endoscopic papillectomy may be safe and effective for management of ampullary adenomas. Careful patient selection and follow-up are mandatory.

Comparison of cold snare and hot snare polypectomy for the resection of sporadic nonampullary duodenal adenomas. Gastrointest Endosc 2022; 96:657-664.e2. [PMID: 35618029 DOI: 10.1016/j.gie.2022.05.007] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/06/2022] [Accepted: 05/14/2022] [Indexed: 02/08/2023]
Abstract
BACKGROUND AND AIMS Nonampullary duodenal adenomas can undergo malignant transformation, making endoscopic resection, often by hot snare (HSP) or cold snare polypectomy (CSP), necessary. Although CSP has been shown to be safer for removal of colon polyps, data comparing these techniques for the resection of duodenal adenomas are limited. Our aim was to compare the safety and efficacy of CSP and HSP for the removal of nonampullary duodenal adenomas. METHODS We performed a retrospective cohort study of patients referred to 2 academic medical centers with a histologically confirmed sporadic, nonampullary duodenal adenoma who underwent endoscopic snare polypectomy between January 1, 2007 and March 1, 2021. Patients with underlying polyposis syndromes were excluded. Outcomes included postprocedural adverse events and polyp recurrence. RESULTS Of 110 total patients, 69 underwent HSP and 41 underwent CSP. Intraprocedural bleeding was similar between both groups, but 7 patients in the HSP group experienced delayed adverse events versus none in the CSP group (P = .04). Fifty-four patients had complete polyp resection and subsequent surveillance endoscopies. Multivariate analysis showed polyp size to be associated with recurrence (per mm; odds ratio, 1.11; 95% confidence interval, 1.04-1.20; P < .01). Endoscopic resection technique (HSP vs CSP) was not a predictor of recurrence (P = .18). CONCLUSIONS HSP led to more delayed adverse events compared with CSP, whereas no significant differences on outcomes were noted, suggesting that CSP is equally effective and potentially safer for the removal of duodenal adenomas.

Abstract
An increasing number of duodenal tumors are being diagnosed over the years, leading to increased confusion regarding the choice of treatment options. Small-to-large tumors and histological types vary from adenoma to carcinoma, and treatment methods may need to be selected according to lesion characteristics. Because of its anatomic characteristics, complications are more likely to occur in the duodenum than in other gastrointestinal organs. Several reports have described the outcomes of conventional endoscopic mucosal resection, endoscopic submucosal dissection, cold snare polypectomy, underwater endoscopic mucosal resection, endoscopic full-thickness resection, and laparoscopic and endoscopic cooperative surgery for duodenal tumors. However, even in the guidelines set out by various countries, only the treatment methods are listed, and no clear treatment strategies are provided. Although there are few reports with a sufficiently high level of evidence, considering the currently available treatment options is essential. In this report, we reviewed previous reports on each treatment strategy, discussed the current issues and prospects, and proposed the best possible treatment strategy.

Prospective single-center feasible study of innovative autorelease bile duct supporter to delay adverse events after endoscopic papillectomy. World J Clin Cases 2022; 10:7785-7793. [PMID: 36158476 PMCID: PMC9372830 DOI: 10.12998/wjcc.v10.i22.7785] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2022] [Revised: 04/18/2022] [Accepted: 06/17/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Conventional endoscopic papillectomy (EP) is safe and effective for the treatment of small papilla adenoma to even large laterally spreading tumors of duodenum lesions. As reported by some existing studies, temporarily placing a prophylactic stent in the pancreatic and bile duct can lower the risk of this perioperative complication.
AIM To evaluate the usefulness, convenience, safety, and short-term results of a novel autorelease bile duct supporter after EP procedure, especially the effectiveness in preventing EP.
METHODS A single-center comparison study was conducted to verify the feasibility of the novel method. After EP, a metallic endoclip and human fibrin sealant kit were applied for protection. The autorelease bile duct supporter fell into the duct segment and the intestinal segment. Specifically, the intestinal segment was extended by nearly 5 cm as a bent coil. The bile was isolated from the pancreatic juice using an autorelease bile duct supporter, which protected the wound surface. The autorelease bile duct supporter fell off naturally and arrived in colon nearly 10 d after the operation.
RESULTS En bloc endoscopic resection was performed in 6/8 patients (75%), and piecemeal resection was performed in 2/8 of patients (25%). None of the above patients were positive for neoplastic lymph nodes or distant metastasis. No cases of mortality, hemorrhage, delayed perforation, pancreatitis, cholangitis or duct stenosis with the conventional medical treatment were reported. The autorelease bile duct supporter in 7 of 8 patients fell off naturally and arrived in colon 10 d after the operation. One autorelease bile duct supporter was successfully removed using forceps or snare under endoscopy. No recurrence was identified during the 8-mo (ranging from 6-9 mo) follow-up period.
CONCLUSION In brief, it was found that the autorelease bile duct supporter could decrease the frequency of procedure-associated complications without second endoscopic retraction. Secure closure of the resection wound with clips and fibrin glue were indicated to be promising and important for the use of autorelease bile duct supporters. Well-designed larger-scale comparative studies are required to confirm the findings of this study.

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.

Abstract
Most ampullary lesions (ALs) are sporadic, involve the major papilla, and are premalignant (adenomas). They are often diagnosed as an incidental finding during endoscopy or imaging procedures. Diagnosis and staging of ALs include endoscopic, histologic, and radiological evaluations. Currently, endoscopic papillectomy is the preferred treatment for ALs in most situations. In this article, we will describe the diagnostic work-up and focus on the endoscopic treatment, including indications, technique, outcomes, complications, and follow-up.

Abstract
BACKGROUND Endoscopic papillectomy is a minimally invasive treatment for benign tumors of the ampulla of Vater or early ampullary carcinoma. However, reported recurrence rates are significant and risk factors for recurrence are unclear. OBJECTIVE The aims of this study were to evaluate the efficacy and safety of endoscopic papillectomy and to identify risk factors for recurrence and adverse events. METHODS All patients who underwent endoscopic papillectomy at five tertiary referral centers between January 2008 and December 2018 were included. Recurrence was defined as the detection of residue on one of the follow-up endoscopies. Treatment success was defined as the absence of tumor residue on the last follow-up endoscopy. RESULTS A total of 227 patients were included. The resections were en bloc in 64.8% of cases. The mean lesion size was 20 mm (range: 3-80) with lateral extension in 23.3% of cases. R0 resection was achieved in 45.3% of cases. The recurrence rate was 30.6%, and 60.7% of recurrences were successfully treated with additional endoscopic treatment. Finally, treatment success was achieved in 82.8% of patients with a median follow-up time of 22.3 months. R1 resection, intraductal invasion, and tumor size > 2 cm were associated with local recurrence. Adverse events occurred in 36.6% of patients and included pancreatitis (17.6%), post-procedural hemorrhage (11.0%), perforation (5.2%), and biliary stenosis (2.6%). The mortality rate was 0.9%. CONCLUSION Endoscopic papillectomy is an effective and relatively well-tolerated treatment for localized ampullary tumors. In this series, R1 resection, intraductal invasion, and lesion size > 2 cm were associated with local recurrence.

Abstract
OBJECTIVES The relationship between the pathological classification and recurrence of duodenal papillary adenomas (DPAs) has not been elucidated. We studied the clinicopathological characteristics of DPAs with different pathological types and conducted long-term follow-up to explore its prognosis and identify methods for appropriate clinical management of DPAs. METHODS In total, 95 DPA cases confirmed by postoperative pathology were enrolled, of which 58 underwent endoscopic papillectomy (EP) and 37 underwent pancreatoduodenectomy (PD). The cases were classified into three anatomical and two histomorphological types according to the histopathology and location of endoscopic features. We analyzed the clinicopathological characteristics of DPAs with different pathological types and investigated the factors associated with recurrence in the EP subgroup. RESULTS Although EP was associated with fewer adverse events, the complete resection rate was significantly lower (72.4% vs. 100.0%, p < 0.001) and the recurrence rate significantly higher than with PD (16.3% vs. 0.0%, p < 0.001). Among eight EP cases with recurrence, six had intra-DPA (75%). A positive resection margin (HR 23.67, 95% CI 6.42-87.27; p < 0.001) and MUC2-negative status (HR 3.47, 95% CI 1.16-10.40; p = 0.026) were independent risk factors for recurrence after EP. CONCLUSION We identified different pathological types within DPAs, which presented varying clinicopathological features. The majority of peri-DPAs and mixed-DPAs were of the intestinal type histologically and EP is the primary recommendation. However, intra-DPA was mainly of the pancreaticobiliary type, which tends to get positive resection margins; thus, surgical resection is more suitable.

Abstract
BACKGROUND AND AIMS Ampullary adenomas (AAs), common in familial adenomatous polyposis (FAP), are precursors to ampullary carcinoma. We assessed the natural history of AAs and factors associated with clinically significant progression (CSP). METHODS Consecutive FAP patients with AAs and at least 2 EGDs were identified from a hereditary GI cancer registry. We assessed the incidence of CSP (increase in size to ≥10 mm and/or development of advanced histology) of AAs. Clinical, endoscopic, and pathologic features between patients with CSP and nonprogressors were compared. RESULTS One hundred forty-three patients with AAs were included. Over a median follow-up of 7.8 years (interquartile range, 4.3-11.1), 41 patients (28.6%) developed CSP for an incidence of 35 per 1000 patient-years. Of 143 patients, 22 (15.6%) progressed to AAs ≥10 mm, 12 (8.5%) progressed to advanced histology, and 7 (4.9%) progressed both in size and histology. Two patients (1.4%) developed ampullary cancer. Male gender, abnormal appearance of the papilla at initial AA detection, prior cholecystectomy, and personal history of extracolonic malignancy were associated with CSP. Neither Spigelman stage nor the adenomatous polyposis coli gene pathogenic variants were associated with CSP. An intervention specifically for AA and not duodenal polyposis was performed in 24% of patients with AAs, including endoscopic papillectomy in 23 patients and duodenectomy in 3 patients at a median observation of 8.2 years. CONCLUSIONS Most FAP patients with AAs did not experience CSP or require resection over 8 years of surveillance. Ampullary cancer was rare. Male gender, abnormal appearance of the papilla at AA detection, cholecystectomy, and history of extracolonic malignancy were associated with CSP. Our findings favor endoscopic surveillance of AAs over expedited resection for most patients with FAP.

Abstract
The Japan Gastroenterological Endoscopy Society has developed the "Clinical Practice Guidelines for Endoscopic Papillectomy (EP)" as a fundamental guideline using scientific approach. EP is a recently spreading therapeutic modality for ampullary tumors ranked as high risk endoscopic technique. Because of the paucity of high level of evidence, strength of recommendations had to be determined by a consensus among specialists. These guidelines, shed light on the following five issues: Indications, Preoperative/intraoperative preparations and techniques, Early adverse events, Therapeutic outcomes and remnants/recurrences, and Follow-up and late adverse events, to guide current clinical practice on EP.

Abstract
Duodenal polyps are found in 0.1 % to 0.8 % of all upper endoscopies. Duodenal adenomas account for 10 % to 20 % of these lesions. They can be sporadic or occur in the setting of a hereditary predisposition syndrome, mainly familial adenomatous polyposis. Endoscopy is the cornerstone of management of duodenal adenomas, allowing for diagnosis and treatment, primarily by endoscopic mucosal resection. The endoscopic treatment of duodenal adenomas has a high morbidity, reaching 15 % in a prospective study, consisting of bleeding and perforations, and should therefore be performed in expert centers. The local recurrence rate ranges from 9 % to 37 %, and is maximal for piecemeal resections of lesions > 20 mm. Surgical resection of the duodenum is flawed with major morbidity and considered a rescue procedure in cases of endoscopic treatment failures or severe endoscopic complications such as duodenal perforations. In this paper, we review the existing evidence on endoscopic diagnosis and treatment of non-ampullary duodenal adenomas.

Abstract
Background: Endoscopic snare papillectomy (ESP) has been established as a safe and effective treatment for ampullary adenomas. However, little is known about the optimal post-procedure follow-up period and the role of routine endoscopic surveillance biopsy following ESP. We aimed to evaluate patient adherence to a 5-year endoscopic surveillance and routine biopsy protocol after ESP of ampullary adenoma. Methods: We reviewed our prospectively collected database (n = 98), all members of which underwent ESP for ampullary lesions from January 2011 to December 2016, for the evaluation of long-term outcomes. The primary outcome was the rate of patient adherence to 5-year endoscopic surveillance following ESP. The secondary outcomes were the diagnostic yield of routine endoscopic biopsy, recurrence rate, and adverse events after endoscopic surveillance in the 5-year follow-up (3-month, 6-month, and every 1 year). Results: A total of 19 patients (19.4%) experienced recurrence during follow-up, all of these patients experienced recurrence within 3 years of the procedure (median 217 days, range 69–1083). The adherence rate for patients with sporadic ampullary adenoma were 100%, 93.5%, and 33.6% at 1, 3, and 5 years after ESP, respectively. The diagnostic yield of routine endoscopic biopsy without macroscopic abnormality was 0.54%. Pancreatitis occurred in four patients (4%, 3 mild, 1 moderate) after surveillance endoscopic biopsy without macroscopic abnormality. Conclusions: Given the low 5-year adherence rate and diagnostic yield of routine endoscopic biopsy with risk of pancreatitis, optimal surveillance intervals according to risk stratification (low grade vs. high grade adenoma/intramucosal adenocarcinoma) may be required to improve patient adherence, and routine biopsy without macroscopic abnormality may not be recommended.

Abstract
Periampullary carcinoma refers to a malignant tumor within 2 cm of the duodenal ampulla. Primary ampullary carcinoma is very rare, accounting for only 0.2% of malignant gastrointestinal tumors. The small intestine accounts for 75% of the length of the gastrointestinal tract, and primary tumors in the small intestine account for only 2% of all gastrointestinal tumors. Here, we report the case of a duodenal ampullary tumor with malignant transformation of parapapillary polyps. The patient had both a primary ampullary tumor and high-grade intraepithelial neoplasia of juxtapapillary adenomatous duodenal polyps.

Abstract
Ampullary adenomatous lesions of the gastrointestinal tract are rare and can be asymptomatic. Therefore, ampullary adenomas with malignant potential require prompt removal, regardless of whether they are adenomatous or carcinomatous lesions. Endoscopic papillectomy is a safe and effective alternative therapy to surgery to treat duodenal papillary lesions in selected patients. Accurate preoperative diagnosis and staging of ampullary adenomatous lesions are critical for predicting prognosis and determining the most appropriate therapeutic approach. Furthermore, the management and prevention of adverse events and endoscopic treatment for remnant or recurrent lesions and surveillance are essential for successful endoscopic management of ampullary adenomatous lesions. This literature review was based on PubMed and MEDLINE and focused on recent advancements in the endoscopic papillectomy technique to provide a comprehensive view of endoscopic papillectomy to treat ampullary adenomatous lesions.

Abstract
BACKGROUND/AIMS The malignant potential of non-ampullary duodenal epithelial tumors (NADETs) is lower compared to that of other gastrointestinal epithelial tumors, but it should not be overlooked. Recently, endoscopic resection (ER) has been proposed as an alternative treatment option for NADETs. Therefore, we aimed to analyze the clinical outcomes of ER of NADETs and determine the factors associated with an incomplete resection. MATERIALS AND METHODS We conducted a retrospective observational study of 54 patients (56 lesions) with NADETs, who underwent ER in the period between October 2006 and March 2016, and analyzed the therapeutic outcomes and procedure-related adverse events. RESULTS Endoscopic mucosal resection (EMR) was performed on 41 lesions, and endoscopic submucosal dissection (ESD) was performed on 15 lesions. The en bloc and complete resection rates were 82% (46/56) and 54% (30/56), respectively. Multivariate logistic regression analyses determined that the resection method (EMR: odds ratio 4.356, 95% confidence interval 1.021-18.585, p=0.047) was independently associated with incomplete resection. The procedure-related bleeding and perforation rates were 4% and 5%, respectively. Recurrence of tumor occurred in one of 44 patients during the median follow-up period of 25 months (range: 6-89 months). CONCLUSION ER is an effective, safe, and feasible treatment option for NADETs. However, the incomplete resection rate increases when EMR is performed. Nevertheless, given the longer procedure time and the technical difficulty associated with ESD, and the excellent long-term outcomes associated with EMR, EMR of NADETs is appropriate, especially in patients with dysplastic lesions.

Expert consensus on endoscopic papillectomy using a Delphi process. Gastrointest Endosc 2021; 94:760-773.e18. [PMID: 33887269 PMCID: PMC8878358 DOI: 10.1016/j.gie.2021.04.009] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2020] [Accepted: 04/11/2021] [Indexed: 12/11/2022]
Abstract
BACKGROUND AND AIMS Consensus regarding an optimal algorithm for endoscopic treatment of papillary adenomas has not been established. We aimed to assess the existing degree of consensus among international experts and develop further concordance by means of a Delphi process. METHODS Fifty-two international experts in the field of endoscopic papillectomy were invited to participate. Data were collected between August and December 2019 using an online survey platform. Three rounds were conducted. Consensus was defined as ≥70% agreement. RESULTS Sixteen experts (31%) completed the full process, and consensus was achieved on 47 of the final 79 statements (59%). Diagnostic workup should include at least an upper endoscopy using a duodenoscope (100%) and biopsy sampling (94%). There should be selected use of additional abdominal imaging (75%-81%). Patients with (suspected) papillary malignancy or over 1 cm intraductal extension should be referred for surgical resection (76%). To prevent pancreatitis, rectal nonsteroidal anti-inflammatory drugs should be administered before resection (82%) and a pancreatic stent should be placed (100%). A biliary stent is indicated in case of ongoing bleeding from the papillary region (76%) or concerns for a (micro)perforation after resection (88%). Follow-up should be started 3 to 6 months after initial papillectomy and repeated every 6 to 12 months for at least 5 years (75%). CONCLUSIONS This is the first step in developing an international consensus-based algorithm for endoscopic management of papillary adenomas. Surprisingly, in many areas consensus could not be achieved. These aspects should be the focus of future studies.

Abstract
BACKGROUND Ectopic pancreas is a rare developmental anomaly that results in a variety of clinical presentations. Patients with ectopic pancreas are mostly asymptomatic, and if symptomatic, symptoms are usually nonspecific and determined by the location of the lesion and the various complications arising from it. Ectopic pancreas at the ampulla of Vater (EPAV) is rare and typically diagnosed after highly morbid surgical procedures such as pancreaticoduodenectomy or ampullectomy. To our knowledge, we report the first case of confirmed EPAV with a minimally invasive intervention.
CASE SUMMARY A 71-year-old male with coronary artery disease, presented to us with new-onset dyspepsia with imaging studies revealing a ‘double duct sign’ secondary to a small subepithelial ampullary lesion. His hematological and biochemical investigations were normal. His age, comorbidity, poor diagnostic accuracy of endoscopy, biopsies and imaging techniques for subepithelial ampullary lesions, and suspicion of malignancy made us acquire histological diagnosis before morbid surgical intervention. We performed balloon-catheter-assisted endoscopic snare papillectomy which aided us to achieve en bloc resection of the ampulla for histopathological diagnosis and staging. The patient’s post-procedure recovery was uneventful. The en bloc resected specimen revealed ectopic pancreatic tissue in the ampullary region. Thus, the benign histopathology avoided morbid surgical intervention in our patient. At 15 mo follow-up, the patient is asymptomatic.
CONCLUSION EPAV is rare and remains challenging to diagnose. This rare entity should be included in the differential diagnosis of subepithelial ampullary lesions. Endoscopic en bloc resection of the papilla may play a vital role as a diagnostic and therapeutic option for preoperative histological diagnosis and staging to avoid morbid surgical procedures.

Safety of Endoscopic Mucosal Resection Using a Bipolar Snare for Superficial Nonampullary Duodenal Epithelial Tumors and the Predictive Factors of Piecemeal Resection. Digestion 2021; 102:682-690. [PMID: 33045711 DOI: 10.1159/000510601] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2020] [Accepted: 08/02/2020] [Indexed: 02/04/2023]
Abstract
INTRODUCTION Endoscopic mucosal resection for small superficial nonampullary duodenal epithelial tumors is a noninvasive treatment; however, perforations can occur. Bipolar snares can reduce the risk of perforation due to small tissue damage. Currently, only few studies have reported endoscopic mucosal resection for small superficial nonampullary duodenal epithelial tumors using a bipolar snare and the effect of preoperative findings. OBJECTIVE To investigate (1) resectability and adverse events of endoscopic mucosal resection using a bipolar snare for small superficial nonampullary duodenal epithelial tumors and (2) the predictions of piecemeal resection. METHODS Between 2007 and 2017, 89 patients with 107 lesions underwent endoscopic mucosal resection using a bipolar snare. Among them, 88 lesions of 77 patients were evaluated. The primary outcome was the incidence of en bloc resection and R0 resection and adverse events. Risk factors associated with piecemeal resection, including preoperative lesion findings, were also examined. RESULTS The incidence rates of en bloc and R0 resections were 85.2 and 48.9%, respectively. Neither intraoperative or delayed perforations nor procedure-related mortality was noted. The nonlifting sign after submucosal injection was associated with an increase in piecemeal resection (odds ratio: 20.3, 95% confidence interval: 2.53-162; p = 0.005). CONCLUSION Endoscopic resection for small superficial nonampullary duodenal epithelial tumors can cause perforation; however, endoscopic mucosal resection using a bipolar snare can be a safe treatment option as it does not cause perforations. The nonlifting sign after submucosal injection is a predictive factor for piecemeal resection.

Abstract
OBJECTIVE To develop the indications and assess an effectiveness of treatment of patients with ampullary tumors followed by mechanical jaundice. MATERIAL AND METHODS There were 26 patients with major duodenal papilla neoplasms for the period 2015-2020 at the Sklifosovsky Research Institute for Emergency Care. RESULTS Twenty patients underwent transpapillary interventions: papillosphincterotomy followed by lithoextraction and bilio-duodenal stenting in 4 (15.3%) patients, bilio-duodenal stenting in 12 (46.1%) patients, nasobiliary drainage in 2 (7.6%) patients, pancreaticoduodenal stenting in 2 (7.6%) patients. Percutaneous transhepatic microcholecystostomy was performed in 6 (23.4%) patients. In all cases, laboratory values decreased in 5-7 days after drainage. Eight (30.7%) patients refused further surgical treatment and were discharged in satisfactory condition. Another 8 (44.5%) patients underwent endoscopic submucosal papillectomy. There were no postoperative complications. Patients were discharged after 5-7 days. Four (22.2%) patients underwent tumor resection via laparotomy. One of these patients required redo laparotomy in postoperative period due to acute perforated duodenal ulcer. Six (33.3%) patients underwent palliative bilio-duodenal stenting. CONCLUSION Invasion of muscle layer or distal parts of the common bile duct, as well as abnormal vascularization are indications for open surgery or palliative endoscopic treatment. Tumor location within mucous and muscle layers without invasion of distal third of the common bile duct and no abnormal vascularization of tumor justify endoscopic papillectomy. Endoscopic approach can be considered as a final minimally invasive method with minimal risk of postoperative complications in case of benign ampullary tumor.

Abstract
OBJECTIVES There are few reports on the long-term prognosis of papillary tumors after endoscopic papillectomy. Here, we report a retrospective study of the therapeutic effects, long-term prognosis, and affecting factors. METHODS The inclusion criteria were papillary adenoma with/without an adenocarcinoma component on biopsy results and ≤10 mm intraductal extension, and the exclusion criteria were moderate to poorly differentiated adenocarcinoma on biopsy results. If no residual lesion was confirmed ≥6 months after the last endoscopic treatment, remission was defined. Subsequently, follow-up endoscopy was scheduled once a year. Surgery was required in the case of adenocarcinoma recurrence or intraductal lesions >10 mm. The rates of adverse events, remission, recurrence, and need for surgery were examined. The affecting factors were calculated. RESULTS There were a total of 253 subjects, including 65 with adenocarcinoma. Pancreatitis (7.5%), bleeding (9.1%) and perforation (2.8%) were observed as adverse events. Among 221 subjects with ≥6 months of follow-up, 212 (95.9%) were in remission. The cumulative recurrence rate using the Kaplan-Meier analysis at 5 years was 16.9% (22 cases), with the need for surgery in 5.9% (5 cases). Intraductal extension on preoperative diagnosis was the only significant risk factor for both recurrence (P < 0.001) and the need for surgery (P = 0.005). The presence of adenocarcinoma had no significant effect. CONCLUSION Although remission was achieved in more than 95% of our patients, we observed a high rate of recurrence at the long-term follow-up, which was significantly associated with intraductal extension but not with the presence of adenocarcinoma.

Abstract
BACKGROUND/PURPOSE Recurrence of ampullary neoplasms after endoscopic papillectomy (EP) has not been well elucidated. This study aimed to clarify the predictive factors for recurrences after EP. We also aimed to investigate the retreatment of the recurrent lesions and their outcomes. METHODS This multicenter, retrospective cohort study included 96 patients with ampullary neoplasms who underwent EP at four tertiary centers between January 2000 and October 2018. RESULTS The pathological diagnoses of resected specimens confirmed adenoma in 62 and adenocarcinoma in 34 patients (six Tis, 24 T1a, three T1b, one inconclusive). Complete resection was confirmed for 79 patients (82.3%). Recurrent lesions were observed in 13 patients (13.5%) during a median follow-up of 3 months (1-36 months) after EP. The predictive factors of recurrence were piecemeal resection, and non-negative horizontal or vertical margin in univariate analysis. Non-negative vertical margin was the only independent predictive factor of recurrence in the multivariate analysis. The recurrent lesions were treated endoscopically in 11 patients. Recurrence after the endoscopic retreatments was observed in one patient. CONCLUSIONS Complete resection with negative vertical margin is an important factor in preventing the recurrence of ampullary neoplasms after EP. Endoscopic retreatments are also feasible for recurrent lesions.

Abstract
BACKGROUND Adenomatous neoplasia in the papilla of Vater needs to be resected in order not to progress. It can be challenging to distinguish between early ampullary malignant lesions and non-invasive adenomas, due to the overlap in symptoms and radiological findings. This retrospective study describes the different findings and treatment decisions taken prior to endoscopic and/or surgical resection of ampullary adenomatous lesions. MATERIALS AND METHODS Patients treated with endoscopic and/or surgical resection for suspected or verified ampullary adenomatous neoplasia, between January 2006 and July 2018, where pre-interventional cross-sectional imaging could not discern an obvious invasive, malignant tumor, were included. Findings were compared against the final diagnosis of the histopathological analysis on the resected specimen. RESULTS In total, 172 met the inclusion criteria. Patients were treated with either surgical resection (n = 96), endoscopic papillectomy (EP) (n = 55) or both (n = 21). The final diagnosis was in 48% ampullary adenocarcinoma, and the remaining had either ampullary adenoma (38%) or non-neoplastic lesions (14%). In patients where symptoms and cross-sectional imaging were suspicious for malignancy, but with no tissue samples that confirmed neoplasia prior to surgical resection, only 47% had adenocarcinoma. The remaining had either adenoma (9%) or non-neoplastic lesions (44%). Adenocarcinoma was revealed in 27% of the patients where endoscopic biopsies had shown adenoma. Patients with adenoma, treated with EP, were cured in 59%. However, 28% were after EP sent for further surgery due to ductal invasion or a finding of adenocarcinoma. CONCLUSIONS In patients with a suspicion of ampullary neoplasia on imaging, attempts should be made to get endoscopic tissue samples before deciding on a treatment strategy. If biopsies show ampullary adenoma, patients should be considered for EP, unless there are clear radiologic or endoscopic signs of malignancy. Patients with adenocarcinoma on endoscopic biopsies should undergo surgical resection.

Abstract
Background and study aims Intraductal extension of ampullary adenoma represents a challenging endoscopic issue. Intraductal radiofrequency ablation (RFA) has been recently suggested, but evidence and standardization of this technique are still lacking. This study aimed to provide a long-term evaluation of clinical efficacy and safety of intraductal RFA ablation with a standardized algorithm of treatment. Patients and methods Data were prospectively collected from consecutive patients with intraductal extension of adenomatous ampullary lesions from January 2016 to November 2018. Endpoints of the study were clinical success evaluated on histology results at the last follow-up, technical success, and adverse events assessment. Results Nine patients with intraductal (biliary ± pancreatic) extension of ampullary adenomas were treated with RFA during the study period. Histology on the papillectomy specimen confirmed intraductal involvement with low-grade dysplasia (LGD) in five cases (56 %), high-grade dysplasia (HGD) in three (33 %), and HGD with intramucosal adenocarcinoma in one patient (11 %). Additional argon plasma coagulation to ablate the adenoma on the duodenal mucosa was applied in five patients (56 %). Technical success was 100 %. One patient (11 %) with failed pancreatic stenting, developing acute pancreatitis after RFA, recovered with medical therapy. After a median follow-up of 21 months (IQR 20-31), six patients (67 %) achieved clinical success being free of recurrence, whereas one was diagnosed with persistence of adenocarcinoma, one with recurrent HGD, and one with recurrent LGD. Conclusions In our experience, intraductal RFA achieved acceptable results after a 2-year follow-up. Further studies are required to confirm our results and to select those patients most likely to respond.

Abstract
BACKGROUND Endoscopic papillectomy is increasingly performed as an alternative to surgery for early ampullary tumors. AIM This retrospective study aimed to evaluate the long-term results of endoscopic papillectomy, the management of cases with incomplete endoscopic resection, and the long-term recurrence rates. METHODS All 46 patients who underwent endoscopic papillectomy for ampullary tumors between November 2003 and March 2018 were retrospectively evaluated. RESULTS The final pathological diagnoses were adenoma (n = 44) and adenocarcinoma (n = 2). Histopathological evaluations after endoscopic papillectomy revealed that complete resection was achieved in 19 patients (19/46, 41.3%). Among the 27 patients with incomplete resection, the margin was histopathologically positive in 14 patients and difficult to evaluate in 13. Additional surgery was performed for 2 of the 14 patients with positive margins. Excluding 2 patients who received additional surgery, 7 of the 25 patients with incomplete resection had recurrence, and 18 had no recurrence during the follow-up period. Ten (77%) of the 13 patients in whom the margin was difficult to evaluate had no recurrence. CONCLUSION Approximately 80% of the patients in whom the histopathological evaluation of the resected margin was difficult had no recurrence even after approximately 5 years of follow-up. Thus, careful observation may be considered for these patients.

Abstract
Ampullary carcinomas of the duodenum are uncommon. Moreover, the diversity in the clinical outcomes of these patients makes it difficult to interpret previous studies and clinical trial results. The difficulty in proper staging of ampullary carcinomas, especially with regard to the T category of the tumor in the TNM system, reflects the anatomic complexity and non-uniform histopathologic subtypes. One major reason for this difficulty in interpretation is that the tumors may arise from any of the three epithelia (duodenal, biliary, or pancreatic) that converge at this location. Generally, ampullary carcinomas are classified into intestinal and pancreaticobiliary types based on morphology and immunohistochemical features. While many studies have described their specific characteristics and clinical impact, the prognostic value of these subtypes is controversial. In recent years, whole-exome sequencing analyses have advanced our understanding of the genomic overview of ampullary carcinoma. Gene mutations serve as prognostic and predictive biomarkers for this disease. Therefore, basic knowledge of the genomic profile of ampullary carcinomas is required for surgeons to understand how best to apply precision medicine as well as surgery and adjuvant therapies. This review provides an overview of the current basic and clinical issues of ampullary carcinoma.

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 & AIMS Ampullary and duodenal cancer are the leading causes of death in patients with familial adenomatous polyposis (FAP) after colectomy has been performed. Risk of duodenal cancer is determined based on Spigelman stage (SS) of duodenal polyposis. Guidelines recommend endoscopic surveillance of the duodenum and visualization of the papilla to stage duodenal polyposis. There is no consensus on whether biopsies should be routinely collected from duodenal papilla and findings included in SS. Additionally, there are no data on the risk of pancreatitis after biopsy collection from papilla of patients with FAP. We studied the incidence of pancreatitis after biopsy of the papilla in patients with FAP and effects of biopsy findings on SS. METHODS We identified consecutive patients with FAP at a single center from January 2011 through December 2018 with ≥1 endoscopy with biopsy of the papilla. Patients with history of foregut surgery were excluded. We identified 273 patients with FAP who had biopsies collected from papilla over 792 EGDs, with 1-8 independent exams with biopsy per patient. We collected demographic, endoscopic, and histology data from patients and calculated SS with vs without biopsy findings. Post-procedural pancreatitis was defined by 2 of the following: abdominal pain, lipase level 3-fold the upper limit of normal, or radiography findings consistent with pancreatitis within 7 days of esophagogastroduodenoscopy (EGD). RESULTS Pancreatitis developed in 2 patients (0.73%): 1 after biopsy of a normal-appearing papilla and 1 after biopsy of an abnormal appearing papilla. Inclusions of biopsy data increased SS in 36 patients (13.2%), with consideration of prophylactic duodenectomy for 3.3%. CONCLUSIONS Pancreatitis after biopsy of the duodenal papilla is rare. Histology data obtained from biopsy of the papilla in patients with FAP can change SS and affect patient management.

Abstract
BACKGROUND Biliary stricture evaluation with brush cytology and intraductal forceps biopsy carries a low sensitivity, but the combination of newer modalities may improve sensitivity. AIM To determine whether the addition of advanced modalities increases diagnostic yield of ERCP-based sampling. METHODS This single-center retrospective study evaluates patients with biliary strictures sampled using brush cytology. Operating characteristics were calculated for individual and combinations of modalities including cholangioscopy, fluoroscopy- and cholangioscopy-directed intraductal biopsy, fluorescence in situ hybridization (FISH), and confocal laser endomicroscopy. Analyses under Standard Criteria (SC) included malignant results as "positive" and Expanded Criteria (EC) included "suspicious" and "high-grade dysplasia" results as "positive." RESULTS A total of 614 patients were included, and 354 (57.8%) received brush cytology alone, which had a sensitivity of 38.5% (SC) to 40.3% (EC) and a specificity of 97.8% (EC) to 99.3% (SC). Combining brush cytology with fluoroscopy-guided biopsy (n = 259, 42.2%) had a sensitivity of 62.5% (SC) to 67.9% (EC) and specificity of 90.2% (EC) to 96.7% (SC). Adding FISH to brush cytology had a sensitivity of 84.2% (SC) to 87.5% (EC) and specificity of 54.1% (SC and EC), while cholangioscopy visualization addition resulted in a sensitivity of 80.4% (SC) to 92.2% (EC) and specificity of 67.3% (EC) to 89.1% (SC). There were no significant differences in sensitivity and specificity using SC and EC. CONCLUSIONS Brush cytology has a low sensitivity, but the addition of other modalities increases sensitivity. There was no difference in specificity between the SC and the EC, supporting the inclusion of "suspicious" impressions with malignant results at our center.
