Project description:Congenital duodenal web (CDW) is an uncommon cause of duodenal obstruction and endoscopic balloon dilatation has been reported in just eight pediatric cases to date. Here we are reporting three cases of CDW managed successfully with balloon dilatation.In 2014 we diagnosed three cases of CDW on the basis of typical radiological and endoscopic findings. Endoscopic balloon dilatation was done under conscious sedation with a through-the-scope controlled radial expansion (CRE) balloon.All three children presented late (median age 8 [range 2 - 9] years) with bilious vomiting, upper abdominal distension, and failure to thrive. One of them had associated Down syndrome and another had horseshoe kidney. In all cases, CDW was observed in the second part of the duodenum beyond the ampulla, causing partial duodenal obstruction. After repeated endoscopic dilatation (2 - 4 sessions), all three patients became asymptomatic. None of the patients experienced complications after balloon dilatation.Duodenal diaphragm should be suspected in patients with abdominal distension with bilious vomiting, even in relatively older children. Endoscopic balloon dilatation is a simple and effective method of treating this condition.

Project description:BackgroundAmpullary adenomas are lesions at the duodenum's major papilla commonly associated with familial adenomatous polyposis (FAP) but may also occur sporadically. Historically, ampullary adenomas were removed surgically, however endoscopic resection has become the preferred method of resection. Most of the literature on management of ampullary adenomas are small single-center retrospective reviews. The objective of this study is to describe endoscopic papillectomy outcomes to further refine management guidelines.MethodsThis is a retrospective study of patients who underwent endoscopic papillectomy. Demographic data were included. Details regarding lesions and procedures were also collected, including endoscopic impression, size, resection method and adjunctive therapies. Chi-square, Kruskal-Wallis rank-sum, and t-tests were performed.ResultsA total of 90 patients were included. 60% patients (54 of 90) had pathology-proven adenomas. 14.4% of all lesions (13 of 90) and 18.5% of adenomas (10 of 54) were treated with APC. Among APC-treated lesions, 36.4% developed recurrence (4 of 11) vs. 7.1% developed residual lesion (1 of 14) (P=0.019). 15.6% of all lesions (14 of 90) and 18.5% of adenomas (10 of 54) reported complications, and the most common was pancreatitis (11.1% and 5.6%). Median follow-up time was 8 months for all lesions and 14 months (range, 1-177 months) for adenomas, with time to recurrence 30 and 31 months (range, 1-137 months), respectively. Recurrence was observed in 16.7% of all lesions (15 of 90) and 20.4% of adenomas (11 of 54). Endoscopic success was observed in 69.2% of all lesions (54 of 78) and 71.4% of adenomas (35 of 49) after removing patients lost to follow-up.ConclusionsEndoscopic papillectomy is an effective method for managing duodenal adenomas. Pathology-proven adenoma should undergo surveillance for at least 31 months. Lesions treated with APC may require closer follow-up and for a prolonged period.

Project description:Common marmosets (Callithrix jacchus) are frequently used for biomedical research but gastrointestinal diseases have been major health problems to maintain captive marmosets. We have diagnosed a novel gastrointestinal disease in marmosets, as which we propose to call 'marmoset duodenal dilation syndrome'; this disease is characterised by proximal duodenal obstruction and dilation. This study aimed to reveal the clinical and pathological findings of this syndrome and establish appropriate diagnostic imaging methods. Animals with the syndrome comprised 21.9% of the necropsy cases at the Central Institute for Experimental Animals in Kawasaki, Japan. The syndrome is characterised by clinical signs included vomiting, bloating, and weight loss. Grossly, all diseased animals exhibited significant dilation of the descending part of the duodenum, which contained a mixture of gas and fluid. The duodenal dilations were definitively diagnosed by contrast radiography. Moreover, a combination of plain radiography and ultrasonography was found to be a viable screening method for diagnosing duodenal dilation. The animals with duodenal dilation characteristically showed adhesions between the descending duodenum and ascending colon with chronic peritonitis. The cause of marmoset duodenal dilation syndrome remains unknown, but was likely multifactorial, including peritoneal adhesion, chronic ulcer, and feeding conditions in this study.

Project description:BackgroundTo assess the short-term outcomes after endoscopic sphincterotomy (EST) plus endoscopic papillary balloon dilation (EPBD) versus EPBD alone and appropriate balloon dilation time in EPBD alone.Materials and methodsA total of 413 patients with common bile duct stones (CBDSs) were included in the EST plus EPBD group and 84 were in the EPBD alone group. We retrospectively evaluated the safety and efficacy between EST plus EPBD and EPBD alone group. The patients in EPBD alone group were assigned to dilation time ≥5 minutes group (n=35) and time <5 minutes group (n=49). Further, we preliminarily discussed the influence of balloon dilation time on the procedure-related complications.ResultsCompared with EST plus EPBD, the patients in EPBD alone group were younger [56.6 (range: 18 to 95) vs. 65.1 (24 to 92) y; P=0.006], had smaller diameter of the largest stone [10.4 (range: 3 to 20) vs. 12.3 (5 to 30) mm; P<0.001] and were lesser frequently performed with jaundice [22 (26.2%) vs. 189 (45.8%); P=0.001]. The mean duration of postoperative hospital stay in EPBD alone group was significantly shorter than EST plus EPBD group [6.3 (range: 1 to 18) vs. 9.2 (1 to 44) d; P<0.001]. The patients in EPBD alone group had higher risk of post endoscopic retrograde cholangiopancreatography pancreatitis than EST plus EPBD group [11 (13.1%) vs. 22 (5.3%); P=0.009]. Patients in the dilation time <5 minutes group had higher risk to suffer from postoperative pancreatitis than the EST plus EPBD group [9 (18.4%) vs. 22 (5.3%); P=0.002], while patients in the dilation time ≥5 minutes group had less procedure-related hemorrhage than the EST plus EPBD group [0 vs. 36 (8.7%); P=0.047].ConclusionLong balloon dilation time in EPBD alone is safe and effective in treating CBDSs.

Project description:BackgroundSporadic nonampullary duodenal adenocarcinoma is a rare malignant neoplasm in which poor prognosis is often associated with delayed diagnosis.ObjectiveA case-control study was designed to evaluate the clinical and endoscopic characteristics of patients with nonampullary duodenal epithelial tumours (NADETs).MethodsPatients with NADETs were chronologically divided into a discovery and a validation sets. Two age- and sex-matched control individuals for each case in the discovery set were randomly selected from individuals without NADET. A prediction model for the presence of NADET, constructed in the discovery set, was evaluated in the validation set.ResultsIn total, 368 adenomas, 81 adenocarcinomas, and 314 controls were analysed. Current smoking, Barrett oesophagus, fundic gland polyps, history of malignant disease, and absence of dyslipidaemia were independently associated with the presence of NADET. The combination of these five factors enabled significant discrimination for NADET in the bulb with a sensitivity of 0.81 in the validation set. We also showed that duodenal adenocarcinomas in the bulb had greater invasive potential than adenocarcinomas in the second portion.ConclusionThe presence of a duodenal tumour in the bulb could be predicted by clinical and endoscopic findings, which helps improve the prognosis and quality of life of patients.

Project description:IntroductionTo develop a simplified scoring system for clinical prediction of difficulty in CBD stone removal to assist endoscopists working in resource-limited settings in deciding whether to proceed with an intervention or refer patients to a center capable of performing additional procedures and interventions.MethodsThis study included patients with CBD stones who underwent ERCP at Pattani Hospital between August 2017 and December 2021. Retrospective cohort data was collected and patients were categorized into two groups: bile duct stones successfully treated by endoscopic biliary sphincterotomy and extraction compared to the former method combined with EPLBD. We explored potential predictors using multivariable logistic regression. The chosen logistic coefficients were transformed into a scoring system based on risk with internal validation via bootstrapping procedure.ResultsAmong the 155 patients who had successful endoscopic therapy for bile duct stones, there were 79 (50.97%) cases of endoscopic biliary sphincterotomy, EPLBD and extraction versus 76 (49.03%) cases without EPLBD. The factors used to derive a scoring system included the size of CBD stones >15 mm, the difference between the stone and distal CBD diameter >2mm, distal CBD arm length <36 mm and stone shape. The score-based model's area under ROC was 0.88 (95% CI: 0.83, 0.93). For clinical use, the range of scores from 0 to 16, was divided into two subcategories based on CBD stone removal difficulty requiring EPLBD to derive the PPV. For scores <5 and ≥ 5, the PPV was 23.40 (p <0.001) and 93.44 (p <0.001) respectively. The Bootstrap sampling method indicated a prediction ability of 0.88 (AuROC, 95% CI: 0.83, 0.94).ConclusionThis scoring system has acceptable prediction performance in assisting endoscopists in their choice of stone removal procedure.

Project description: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. Video Video 1 EMR techniques of duodenal and ampullary adenomas.

Project description:BackgroundThere is a discrepancy in the surgical and endoscopic literature for managing duodenal perforations. Although often managed conservatively, surgical repair is the standard treatment for duodenal perforations. This contrasts with the gastroenterology literature, which now recommends endoscopic repair of duodenal perforations, which are more frequently iatrogenic from the growing field of advanced endoscopic procedures. This study aims to provide a scoping review to summarize the current literature content and quality on endoscopic repair of duodenal perforations.MethodsThe protocol for performing this scoping review was outlined by the Joanna Briggs Institute. All studies that reported primary outcomes of patients who had undergone endoscopic repair of duodenal perforations before February 2022, regardless of perforation etiology or repair type were reviewed, with studies after 1999 meeting inclusion criteria. The study excluded articles that did not report clinical outcomes of endoscopic repair, articles that did not describe where in the gastrointestinal tract the endoscopic repair occurred, pediatric patients, and animal studies.Results7606 abstracts were screened, with 474 full articles reviewed and 152 studies met inclusion criteria. 560 patients had duodenal perforations repaired endoscopically, with a technical success rate of 90.4% and a survival rate of 86.7%. Most of these perforations (74.5%) were iatrogenic from endoscopic procedures or surgery. Only one randomized control trial (RCT) was found, and 53% of studies were case reports.ConclusionThese results suggest that endoscopic repair could emerge as a viable first-line treatment for duodenal perforation and highlight the need for more high-quality research in this topic.
