RESUMO
INTRODUCTION: Underwater endoscopic mucosal resection (UEMR) and cold snare polypectomy (CSP) are novel endoscopic procedures for superficial nonampullary duodenal epithelial tumors (SNADET). However, consensus on how to use both procedures appropriately has not been established. In this study, we evaluated treatment outcomes of both procedures, including resectability. METHODS: In this single-center randomized controlled study conducted between January 2020 and June 2022, patients with SNADET ≤12 mm were randomly allocated to UEMR and CSP groups. The primary end point was sufficient vertical R0 resection (SVR0), which was defined as R0 resection including a sufficient submucosal layer. We compared treatment outcomes including SVR0 rate between groups. RESULTS: The SVR0 rate was significantly higher in the UEMR group than in the CSP group (65.6% vs 41.5%, P = 0.01). By contrast, the R0 resection rate was not significantly different between study groups (70.3% vs 61.5%, P = 0.29). The submucosal layer thickness was significantly greater in the UEMR group than in the CSP group (median 546 [range, 309-833] µm vs 69 [0-295] µm, P < 0.01). CSP had a shorter total procedure time (median 12 [range, 8-16] min vs 1 [1-3] min, P < 0.01) and fewer total bleeding events (9.4% vs 1.5%, P = 0.06). DISCUSSION: UEMR has superior vertical resectability compared with CSP, but CSP has a shorter procedure time and fewer bleeding events. Although CSP is preferable for most small SNADET, UEMR should be selected for lesions that cannot be definitively diagnosed as mucosal low-grade neoplasias.

BACKGROUND AND AIMS: Nonampullary duodenal neuroendocrine tumors (NAD-NETs) are rare, with limited evidence regarding endoscopic treatment. This study investigated the efficacy and safety of endoscopic resection of well-differentiated NAD-NETs and evaluated long-term outcomes, including local recurrence and metastasis. METHODS: Seventy-eight patients with NAD-NETs who underwent endoscopic resection between January 2011 and August 2022 were included. Clinicopathologic characteristics and treatment outcomes were collected and analyzed. RESULTS: En-bloc resection was achieved for 74 tumors (94.9%) and R0 resection for 68 tumors (87.2%). Univariate analysis identified tumors in the second part of the duodenum, tumor size ≥10 mm, and muscularis propria invasion as risk factors for noncurative resection. Two patients with R1 resection (vertical margin involvement) and 2 patients with lymphovascular invasion underwent additional surgery. Four patients experienced adverse events (5.1%), including 2 cases of delayed bleeding and 2 cases of perforation, all successfully managed conservatively. During a median follow-up period of 62.6 months, recurrence and lymph node metastasis were only detected in 1 patient with R1 resection 3 months after the original procedure. CONCLUSIONS: Endoscopic resection is safe and effective and provides a favorable long-term outcome for patients with well-differentiated NAD-NETs without regional lymph node or distant metastasis.

BACKGROUND: Environmental enteric dysfunction (EED) is an enigmatic disorder of the small intestine that is postulated to play a role in childhood undernutrition, a pressing global health problem. Defining the incidence of this disorder, its pathophysiological features, and its contribution to impaired linear and ponderal growth has been hampered by the difficulty in directly sampling the small intestinal mucosa and microbial community (microbiota). METHODS: In this study, among 110 young children (mean age, 18 months) with linear growth stunting who were living in an urban slum in Dhaka, Bangladesh, and had not benefited from a nutritional intervention, we performed endoscopy in 80 children who had biopsy-confirmed EED and available plasma and duodenal samples. We quantified the levels of 4077 plasma proteins and 2619 proteins in duodenal biopsy samples obtained from these children. The levels of bacterial strains in microbiota recovered from duodenal aspirate from each child were determined with the use of culture-independent methods. In addition, we obtained 21 plasma samples and 27 fecal samples from age-matched healthy children living in the same area. Young germ-free mice that had been fed a Bangladeshi diet were colonized with bacterial strains cultured from the duodenal aspirates. RESULTS: Of the bacterial strains that were obtained from the children, the absolute levels of a shared group of 14 taxa (which are not typically classified as enteropathogens) were negatively correlated with linear growth (length-for-age z score, r = -0.49; P = 0.003) and positively correlated with duodenal proteins involved in immunoinflammatory responses. The representation of these 14 duodenal taxa in fecal microbiota was significantly different from that in samples obtained from healthy children (P<0.001 by permutational multivariate analysis of variance). Enteropathy of the small intestine developed in gnotobiotic mice that had been colonized with cultured duodenal strains obtained from children with EED. CONCLUSIONS: These results provide support for a causal relationship between growth stunting and components of the small intestinal microbiota and enteropathy and offer a rationale for developing therapies that target these microbial contributions to EED.

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

OBJECTIVE: To determine if oesophago-gastro-duodenoscopy (OGD) generates increased levels of aerosol in conscious patients and identify the source events. DESIGN: A prospective, environmental aerosol monitoring study, undertaken in an ultraclean environment, on patients undergoing OGD. Sampling was performed 20 cm away from the patient's mouth using an optical particle sizer. Aerosol levels during OGD were compared with tidal breathing and voluntary coughs within subject. RESULTS: Patients undergoing bariatric surgical assessment were recruited (mean body mass index 44 and mean age 40 years, n=15). A low background particle concentration in theatres (3 L-1) enabled detection of aerosol generation by tidal breathing (mean particle concentration 118 L-1). Aerosol recording during OGD showed an average particle number concentration of 595 L-1 with a wide range (3-4320 L-1). Bioaerosol-generating events, namely, coughing or burping, were common. Coughing was evoked in 60% of the endoscopies, with a greater peak concentration and a greater total number of sampled particles than the patient's reference voluntary coughs (11 710 vs 2320 L-1 and 780 vs 191 particles, n=9 and p=0.008). Endoscopies with coughs generated a higher level of aerosol than tidal breathing, whereas those without coughs were not different to the background. Burps also generated increased aerosol concentration, similar to those recorded during voluntary coughs. The insertion and removal of the endoscope were not aerosol generating unless a cough was triggered. CONCLUSION: Coughing evoked during OGD is the main source of the increased aerosol levels, and therefore, OGD should be regarded as a procedure with high risk of producing respiratory aerosols. OGD should be conducted with airborne personal protective equipment and appropriate precautions in those patients who are at risk of having COVID-19 or other respiratory pathogens.

Duodenal mucosal resurfacing (DMR) is a new endoscopic ablation technique aimed at improving glycemia and metabolic control in patients with type 2 diabetes mellitus (T2DM). DMR appears to improve insulin resistance, which is the root cause of T2DM, but its mechanism of action is largely unknown. Bile acids function as intestinal signaling molecules in glucose and energy metabolism via the activation of farnesoid X receptor and secondary signaling [e.g., via fibroblast growth factor 19 (FGF19)], and are linked to metabolic health. We investigated the effect of DMR and glucagon-like peptide-1 (GLP-1) on postprandial bile acid responses in 16 patients with insulin-dependent T2DM, using mixed meal tests performed at the baseline and 6 mo after the DMR procedure. The combination treatment allowed discontinuation of insulin treatment in 11/16 (69%) of patients while improving glycemic and metabolic health. We found increased postprandial unconjugated bile acid responses (all P < 0.05), an overall increased secondary bile acid response (P = 0.036) and a higher 12α-hydroxylated:non-12α-hydroxylated ratio (P < 0.001). Total bile acid concentrations were unaffected by the intervention. Postprandial FGF19 and 7-α-hydroxy-4-cholesten-3-one (C4) concentrations decreased postintervention (both P < 0.01). Our study demonstrates that DMR with GLP-1 modulates the postprandial bile acid response. The alterations in postprandial bile acid responses may be the result of changes in the microbiome, ileal bile acid uptake and improved insulin sensitivity. Controlled studies are needed to elucidate the mechanism linking the combination treatment to metabolic health and bile acids.NEW & NOTEWORTHY Glycemic and metabolic improvements are seen in patients with type 2 diabetes after replacing their insulin therapy with DMR and GLP-1. These changes are accompanied by changes in postprandial bile acid concentrations: increased unconjugated and secondary bile acids.

INTRODUCTION: In patients with familial adenomatous polyposis, the Spigelman classification is recommended for staging and risk stratification of duodenal adenomatosis. Although the classification has been used for decades, it has never been formally validated. METHODS: We included consecutive FAP patients undergoing upper gastrointestinal endoscopic surveillance and evaluated the inter- and intrarater reliability of the Spigelman classification. RESULTS: The interrater reliability of the endoscopic parameters and the Spigelman classification was good and excellent, respectively. The intrarater reliability of the endoscopic parameters and the Spigelman classification was moderate and good, respectively. DISCUSSION: The results support continued use of the Spigelman classification as the primary end point for future studies and as key endoscopic performance measure.

BACKGROUND: Propofol combined with opioids can reduce the dosage of propofol and improve the safety of endoscopy. However, there are few studies on propofol combined with S-ketamine in children undergoing gastro-duodenoscopy. We aim to determine the sedative effect and safety of different doses of S-ketamine in combination with propofol in school-aged children undergoing gastro-duodenoscopy. METHODS: This is a prospective, randomized trial. Totally, 120 school-aged children who underwent gastro-duodenoscopy were randomly allocated into Group P, Group S0.3, Group S0.5 and Group S0.7. During induction, children in Group P, Group S0.3, Group S0.5 and Group S0.7 received 0, 0.3 mg.kg-1, 0.5 mg.kg-1 and 0.7 mg.kg-1 S-ketamine, respectively, following 3 mg.kg-1 propofol injection. During gastro-duodenoscopy, 1 mg.kg-1 of propofol was added according to the condition of the children and the BIS (bispectral index) value. The primary outcome was smooth placement rate of the first endoscope insertion. The secondary outcome was the times of additional propofol, the total amount of propofol, adverse events, recovery time, length of PACU (post anesthesia care unit) stay and endoscopist satisfaction. RESULTS: The smooth placement rate of the first endoscope insertion in Group P, Group S0.3 and Group S0.5 was significantly lower than that in Group S0.7 (16.70%, 34.50%, 50.00% vs. 83.30%, respectively, P < 0.001). The times of additional propofol in Group S0.3 (P = 0.018), Group S0.5 (P = 0.014) and Group S0.7 (P = 0.001) were significantly less than Group P. The total amount of propofol in Group S0.7 was significantly less than Group P (P < 0.001). The incidence of intraoperative hypotension in Group S0.5 and Group S0.7 was low. Group S0.7 had significantly higher incidence of postoperative dizziness (P = 0.003), longer PACU stay (P = 0.018) and higher endoscopist satisfaction (P = 0.001) than Group P. There was no difference in the recovery time among groups. CONCLUSION: S-ketamine (0.7 mg.kg-1) in combination with propofol can provide satisfactory sedative effect and reduce the dosage of propofol in school-aged children undergoing gastro-duodenoscopy, but there are higher incidence of postoperative dizziness and longer PACU stay.

An 80-year-old female with a mechanic mitral valve treated with acenocumarol was admitted to the hospital due to tarry stools over the last two days and hemoglobin levels of 5.6 g/dl. She had not biliary pathology. An emergency esophagogastroduodenoscopy showed lots of fresh clots over the second part of the duodenum that seemed to come from the major papilla. A duodenoscopy was performed in order to obtain a direct view, showing a huge clot near the papilla. Its removal with a polypectomy snare revealed a large duodenum diverticulum with little saculations inside, one of which showed a visible, actively bleeding vessel. Sclerosis with epinephrine was performed and subsequently, two through-the-scope Cook® 11 mm clips were placed, achieving the cessation of the hemorrhage. Several attempts with different clips were needed since they were separated by the elevator nail of the duodenoscope. No complications developed during the procedure or once anticoagulation was restarted.

BACKGROUND: The standard oesophago-gastro-duodenoscopy procedure is performed with a single endoscopist (SE). Nurse-assisted (NA) oesophago-gastro-duodenoscopies have not yet been studied. We aimed to evaluate the efficacy of an NA endoscopy compared to an SE endoscopy. METHODS: A prospective, single-center, randomized trial, in which 500 adult patients were divided into two groups. In the first group, patients underwent an endoscopy with an SE. In the second group, the endoscopy was performed with an NA. The ease of the procedure (scores 1-4; 1 difficult, 2 satisfactory, 3 easy, 4 veryeasy), evaluation of patient satisfaction (scores 1-4; 1 uncomfortable, 2 satisfactory, 3 comfortable, 4 verycomfortable), total time of the procedure and vocal cord observation were determined as quality indicators. RESULTS: Mean patient satisfaction scores in groups 1 and 2 were 2.98±0.79 and 3.11±0.78, respectively (p=0.043), with uncomfortable ratings in 5.2% vs 4%, satisfactory in 16.8% vs 13.2%, comfortable in 53.2% vs 50.4%, and very comfortable in 24.8% vs 32.4% of patients in groups 1 and 2, respectively. Retching rates during the procedure were 54.4% and 45.2% (p=0.040) in groups 1 and 2, respectively. No differences were seen in vocal cord observation (54.4% vs 56.0%), total procedure time (2.35±1.56 vs 2.41±1.48min) and easy score (3.26±0.603 vs 3.25±0.64) in groups 1 and 2 for the procedures. Very easy, easy, satisfactory, and difficult ratings were given by 33.6% vs 34.8%, 60.4% vs 56.4%, 4.8% vs 7.6% and 1.2% vs 1.2% of groups 1 and 2, respectively. CONCLUSIONS: Compared with the conventional method, the assisted endoscopic technique provides more comfort and less gag reflex without increasing the processing time or difficulty of performing the procedure.

Small bowel cancer (SBC) is the malignancy with the highest standardized incidence ratio in Lynch syndrome (LS) patients. Of all SBCs, about 50% are duodenal cancers (DCs), therefore being accessible by esophago-gastro-duodenoscopy (EGD) for surveillance. We asked whether early detection of DC is possible for LS patients undergoing surveillance by EGD and if surveillance should be limited to specific subgroups. Data for LS patients with DC were retrieved from the registry of the German Consortium for Familial Intestinal Cancer. Patients undergoing active surveillance by EGDs (surveillance group) were compared to those who did not (nonsurveillance group) regarding tumor stage at diagnosis. Union for International Cancer Control stages I-IIA were defined as early stage disease and IIB-IV as advanced stage disease. Statistical analysis was performed using Fisher's exact test. Among 2015 patients with pathogenic variants in any mismatch-repair-gene, 47 patients with 49 DCs were identified. In 10% of cases, patients were under 35 years at diagnosis; family and personal tumor history did not correlate with DC diagnosis. Pathogenic germline variants in MSH6, PMS2 or EPCAM were present in 10% of patients. Statistical analysis could be performed on 13 DC patients in the surveillance group and 14 in the nonsurveillance group. Early detection was possible for 71% of patients in the surveillance group and 29% of patients in the nonsurveillance group (P = .021). Early detection of DC by EGD in LS patients is feasible regardless of family history, mutational status and should start no later than 25 years of age.

Though superficial non-ampullary duodenal epithelial tumors (SNADETs) have been traditionally considered rare, there is a growing detection under the development and widespread of endoscopic techniques in recent times. Many case studies have revealed early manifestations of lesions through advanced endoscopic technology, however, because of the low incidence of duodenal tumors and challenges in diagnosing, the preoperative diagnosis criteria have not been established so far. In spite of this, recently the increasing detection rate of early duodenal epithelial lesions enhances the demand for minimally invasive treatment as well. The most suitable therapeutic endoscopic modality to remove duodenal lesions should be selected according to the size, location and histological invasive depth of duodenal lesions. Nevertheless, due to the special anatomical structure of the duodenum, the incidence of complications is much higher than in any other part of the digestive tract. To prevent these adverse events prophylactically, a few novel strategies have been applied effectively after resection. This review describes the current status of preoperative endoscopic diagnosis and endoscopic resection approaches, as well as countermeasures for avoiding procedure-related complications.

BACKGROUND AND AIMS: Differentiating superficial non-ampullary duodenal epithelial tumors (SNADETs) that harbor malignant potential is important. We developed a simple scoring system and investigated whether it enables the differentiation of low-grade adenoma and high-grade adenoma/adenocarcinoma. PATIENTS AND METHODS: We retrospectively enrolled 197 consecutive patients with 207 SNADETs who underwent endoscopic resection at NTT Medical Center Tokyo between March 2016 and May 2019. Endoscopic findings were compared between Vienna Classification (VCL) C3 and C4/5 lesions. A multivariate logistic regression analysis was performed to develop a scoring system to identify VCL C4/5 lesions. The efficacy of our scoring system was elucidated among five novice and five expert endoscopists. RESULTS: Of 207 SNADETs, 66 and 141 lesions were pathologically diagnosed as VCL C3 and C4/5. A multivariate logistic regression analysis identified a tumor diameter of 10-19 mm (OR, 3.81; 95% CI, 1.02-14.2; P = 0.04), a tumor diameter ≥20 mm (OR, 95.2; 95% CI, 10.4-871.0; P < 0.001), a red color (OR, 14.5; 95% CI, 3.55-59.6; P < 0.001), the presence of irregular surface pattern (OR, 12.4; 95% CI, 3.00-51.4; P < 0.001), and the presence of irregular vessel pattern (OR, 13.7; 95% CI, 4.03-46.6; P < 0.001) as independent significant predictors of VCL C4/5. Considering these results, we developed a scoring system. Using an appropriate cutoff value, the diagnostic accuracy, sensitivity and specificity were calculated as 92%, 95% and 93%. The average diagnostic accuracy did not differ between novice and expert endoscopists (86% vs 87%, P = 0.76). CONCLUSIONS: Our scoring system was useful for differentiating VCL C3 and C4/5 lesions.

Duodenal duplication cyst (DDC) is a rare form of intestinal malformation (2-12% of all gastrointestinal duplications). There are many difficulties in diagnosis and management of DDC. We present a case of successful endoscopic transluminal treatment of DDC in a 30-year-old female. She complained of epigastric pain, nausea and vomiting, weight loss of 5 kg over the past 3 months. Laparoscopic cholecystectomy for gallstone disease was performed 18 months prior to admission. Examination revealed a cyst 52×60?35 mm in descending part of duodenum. There was a calculus inside the cyst. Transluminal endoscopic cyst fenestration was performed. Histological examination confirmed DDC. According to control duodenoscopy data, cyst was collapsed. The patient remains asymptomatic three months after surgery. DDC is a rare disease of gastrointestinal tract, which should be differentiated first with choledochocele Todani type III and intraluminal duodenal diverticulum. Endoscopic treatment may be an adequate alternative to traditional interventions in some cases.

BACKGROUND: The duodenum has become a metabolic treatment target through bariatric surgery learnings and the specific observation that bypassing, excluding or altering duodenal nutrient exposure elicits favourable metabolic changes. Duodenal mucosal resurfacing (DMR) is a novel endoscopic procedure that has been shown to improve glycaemic control in people with type 2 diabetes mellitus (T2D) irrespective of body mass index (BMI) changes. DMR involves catheter-based circumferential mucosal lifting followed by hydrothermal ablation of duodenal mucosa. This multicentre study evaluates safety and feasibility of DMR and its effect on glycaemia at 24 weeks and 12 months. METHODS: International multicentre, open-label study. Patients (BMI 24-40) with T2D (HbA1c 59-86 mmol/mol (7.5%-10.0%)) on stable oral glucose-lowering medication underwent DMR. Glucose-lowering medication was kept stable for at least 24 weeks post DMR. During follow-up, HbA1c, fasting plasma glucose (FPG), weight, hepatic transaminases, Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), adverse events (AEs) and treatment satisfaction were determined and analysed using repeated measures analysis of variance with Bonferroni correction. RESULTS: Forty-six patients were included of whom 37 (80%) underwent complete DMR and 36 were finally analysed; in remaining patients, mainly technical issues were observed. Twenty-four patients had at least one AE (52%) related to DMR. Of these, 81% were mild. One SAE and no unanticipated AEs were reported. Twenty-four weeks post DMR (n=36), HbA1c (-10±2 mmol/mol (-0.9%±0.2%), p<0.001), FPG (-1.7±0.5 mmol/L, p<0.001) and HOMA-IR improved (-2.9±1.1, p<0.001), weight was modestly reduced (-2.5±0.6 kg, p<0.001) and hepatic transaminase levels decreased. Effects were sustained at 12 months. Change in HbA1c did not correlate with modest weight loss. Diabetes treatment satisfaction scores improved significantly. CONCLUSIONS: In this multicentre study, DMR was found to be a feasible and safe endoscopic procedure that elicited durable glycaemic improvement in suboptimally controlled T2D patients using oral glucose-lowering medication irrespective of weight loss. Effects on the liver are examined further. TRIAL REGISTRATION NUMBER: NCT02413567.

INTRODUCTION: Nonalcoholic fatty liver disease (NAFLD) is an obesity-related disorder that is rapidly increasing in incidence and is considered the hepatic manifestation of the metabolic syndrome. The gut microbiome plays a role in metabolism and maintaining gut barrier integrity. Studies have found differences in the microbiota between NAFLD and healthy patients and increased intestinal permeability in patients with NAFLD. Fecal microbiota transplantation (FMT) can be used to alter the gut microbiome. It was hypothesized that an FMT from a thin and healthy donor given to patients with NAFLD would improve insulin resistance (IR), hepatic proton density fat fraction (PDFF), and intestinal permeability. METHODS: Twenty-one patients with NAFLD were recruited and randomized in a ratio of 3:1 to either an allogenic (n = 15) or an autologous (n = 6) FMT delivered by using an endoscope to the distal duodenum. IR was calculated by HOMA-IR, hepatic PDFF was measured by MRI, and intestinal permeability was tested using the lactulose:mannitol urine test. Additional markers of metabolic syndrome and the gut microbiota were examined. Patient visits occurred at baseline, 2, 6 weeks, and 6 months post-FMT. RESULTS: There were no significant changes in HOMA-IR or hepatic PDFF in patients who received the allogenic or autologous FMT. Allogenic FMT patients with elevated small intestinal permeability (>0.025 lactulose:mannitol, n = 7) at baseline had a significant reduction 6 weeks after allogenic FMT. DISCUSSION: FMT did not improve IR as measured by HOMA-IR or hepatic PDFF but did have the potential to reduce small intestinal permeability in patients with NAFLD.

BACKGROUND: Esophagogastroduodenoscopy (EGD) provides an indispensable and unambiguous inspection allowing the discovery upper gastrointestinal lesions. However, many patients are anxious about undergoing EGD. Few studies have investigated the influence on patients' vital signs and tolerance during EGD using subjective and objective assessments. This study was a prospective randomized controlled study that investigated the influence of audio and visual distraction on EGD. METHODS: We randomly divided 289 subjects who underwent EGD into 4 groups (control group, audio group, visual group, combination group) and examined their vital signs, heart rate variability (HRV), psychological items, and acceptance of distraction. RESULTS: Pulse rate (PR) at post-distraction and post-EGD in the 3 distraction groups were significantly lower than those of control group (p < 0.001 and p < 0.01, respectively). Blood pressure (BP) during and post-EGD was significantly higher than that at pre-EGD in control group (p < 0.05), but no significant elevation of BP was observed during the latter half of EGD and post-EGD in the 3 distraction groups. BP at post-distraction improved significantly compared to pre-distraction in the 3 distraction groups (p < 0.05). There was a significant difference in the low-frequency (LF) power/ high-frequency (HF) power at post-distraction and post-EGD among the 4 groups (p < 0.001 and p < 0.001, respectively). The LF power/HF power at post-distraction and post-EGD in the 3 distraction groups was significantly lower than that in control group (p < 0.05). Several items of profile of mood states (POMS) and the impression of EGD at post-distraction improved significantly compared to those at pre-distraction among the 3 distraction groups (p < 0.05). Visual analog scale (VAS) of willingness for the next use of distraction in the 3 distraction groups was excellent because VAS was more than 70. CONCLUSIONS: Distractions effectively improved psychological factors, vital signs and some of HRV at pre and post-EGD. Distractions may suppress BP elevation during the latter half of EGD and lead to stability of HRV on EGD. TRIAL REGISTRATION: This prospective trial was registered in the University Hospital Medical Information Network (UMIN) Clinical Trials Registry as UMIN000029637. Registered on 20 October 2017.

PURPOSE OF REVIEW: The purpose of this review was to examine the historical roots of endoscopic management of ampullary lesions and explore emerging data on improved techniques, technologies, and outcomes. Of specific interest was answering whether there exists a reasonable body of data to support one resection technique or strategy above others. RECENT FINDINGS: Review of recent literature suggests the continued use of endoscopic ampullectomy is a safe and effective means of curative treatment of ampullary adenomas. Complications are relatively infrequent and complete endoscopic resection is possible in a majority of cases, with proper patient and lesion selection. Greater than 2 decades of experience with endoscopic ampullectomy have shown this to be a viable, well-tolerated, and highly effective means of treating ampullary adenomas. While few concrete guidelines exist to advise endoscopists on the ideal technique for resection, experience, patient selection, and prior planning can greatly influence the technical and clinical success of endoscopic ampullectomy.

BACKGROUND: Pyloric gland adenomas (PGAs) are very rare and underdiagnosed, mostly be founded in the stomach. Similar to colorectal adenomas they have a high risk of malignant transformation to adenocarcinoma up to 12-47â%. Endoscopic resections in the duodenum harbor a significant risk of complications. EMR is the current standard technique for treatment of duodenal non-ampullary adenomas. Complete resection rates are considerably high at about 90â%. Adverse events as bleeding was reported up to 25â%. ESD is not recommended for resection of duodenal lesions since the perforation rate may be as high as 35â%. Use of EFTR in the duodenum are limited to a single case study of 20 patients. CASE: A 67 year old patient with attenuated polyposis coli presented for screening. Gastroscopy showed a 20âmm large, non-ampullary lesions in the proximal duodenum (pars I). The margins of the duodenal lesions were marked with a high-frequency (HF) probe. An integrated balloon dilatation (20âmm) of the upper esophageal sphincter and the pylorus was performed to facilitate advancing of the gastroduodenal FTRD® (Ovesco Endoscopy AG). After pulling the duodenal lesion into the cap with a grasper the FTRD clip was deployed and the lesion immediately resected with the preloaded snare. A single-shot antibiotic prophylaxis with 2âg ceftriaxone i.âv. was administered during the intervention. Second-look endoscopy was scheduled 24âh after resection. The resectat showed histologically a gastric type adenoma of 18âmm in the proximal duodenum (immunohistochemistry positive for Mucin-1, Mucin-5, Mib 1). CONCLUSION: Herein we present the first case of duodenal EFTR in a patient with attenuated FAP and a PGA. There are currently no specific guidelines for the removal and surveillance. ASGE recommends resection and surveillance endoscopy at 3-5 years interval.
