RESUMEN
INTRODUCTION: The study aimed to develop international consensus recommendations on the safe use of lumen-apposing metal stents (LAMSs) for on- and off-label indications. METHODS: Based on the available literature, statements were formulated and grouped into the following categories: general safety measures, peripancreatic fluid collections, endoscopic ultrasound (EUS)-biliary drainage, EUS-gallbladder drainage, EUS-gastroenterostomy, and gastric access temporary for endoscopy. The evidence level of each statement was determined using the Grading of Recommendations Assessment, Development, and Evaluation methodology.International LAMS experts were invited to participate in a modified Delphi process. When no 80% consensus was reached, the statement was modified based on expert feedback. Statements were rejected if no consensus was reached after the third Delphi round. RESULTS: Fifty-six (93.3%) of 60 formulated statements were accepted, of which 35 (58.3%) in the first round. Consensus was reached on the optimal learning path, preprocedural imaging, the need for airway protection and essential safety measures during the procedure, such as the use of Doppler, and measurement of the distance between the gastrointestinal lumen and the target structure. Specific consensus recommendations were generated for the different LAMS indications, covering, among others, careful patient selection, the preferred size of the LAMS, the need for antibiotics, the preferred anatomic location of the LAMS, the need for coaxial pigtail placement, and the appropriate management of LAMS-related adverse events. DISCUSSION: Through a modified international Delphi process, we developed general and indication-specific experience- and evidence-based recommendations on the safe use of LAMS.

BACKGROUND: Extensive esophageal endoscopic submucosal dissections (ESDs) without preventive measures carry a high risk of stricture. Oral steroids and local injection of triamcinolone acetonide have proven to be effective in Asia for the prevention of esophageal stricture. This study aimed to assess the efficacy of a systematic steroid administration protocol for stricture prevention in a Western center. METHODS: A retrospective review was conducted of all esophageal ESDs performed at H.U.B. Erasme Hospital, Brussels between 2016 and 2022. Injection of triamcinolone was performed for mucosal defects between 50% and 89% of the circumference. We added oral corticosteroids for patients with resections of ≥90% of the circumference. The primary outcome was the incidence of symptomatic stenosis at 3 months. Secondary outcomes included the cumulative stricture rate assessed by endoscopy within 6 months of ESD. Potential risk factors of stricture were evaluated with univariate and multivariate analysis. RESULTS: 111 patients underwent 130 esophageal ESDs, with 59 patients receiving triamcinolone acetonide local injection and eight receiving local and oral corticosteroids. The primary outcome demonstrated a stricture incidence of 8.4%. The cumulative stricture rate assessed by endoscopy within 6 months of ESD was 10.4%. A mucosal defect of ≥60 mm in length was associated with a 15-fold increased risk of stricture, with circumferential extent also identified as being an independent prognostic factor for stricture. CONCLUSIONS: Our protocol led to a low stricture rate, even after extensive resection. As a single session treatment without systemic side effects, triamcinolone injection could provide benefits as a preventive method after large esophageal resections.
RESUMEN
BACKGROUND: This study evaluated the safety and efficacy of salvage endoscopic submucosal dissection (ESD) for Barrett's neoplasia recurrence after radiofrequency ablation (RFA). METHODS: Data from patients at 16 centers were collected for a multicenter retrospective study. Patients who underwent at least one RFA treatment for Barrett's esophagus and thereafter underwent further esophageal ESD for neoplasia recurrence were included. RESULTS: Data from 56 patients who underwent salvage ESD between April 2014 and November 2022 were collected. Immediate complications included one muscular tear (1.8%) treated with stent (Agree classification: grade IIIa). Two transmural perforations (3.6%; treated with clips) and five muscular tears (8.9%; two treated with clips) had no clinical impact and were not considered as adverse events. Seven patients (12.5%) developed strictures (grade IIIa), which were treated with balloon dilation. Histological analysis showed 36 adenocarcinoma, 17 high grade dysplasia, and 3 low grade dysplasia. En bloc and R0 resection rates were 89.3% and 66.1%, respectively. Resections were curative in 33 patients (58.9%), and noncurative in 22 patients (39.3%), including 11 "local risk" (19.6%) and 11 "high risk" (19.6%) resections. At the end of follow-up with a median time of 14 (0-75) months after salvage ESD, and with further endoscopic treatment if necessary (RFA, argon plasma coagulation, endoscopic mucosal resection, ESD), neoplasia remission ratio was 37/53 (69.8%) and the median remission time was 13 (1-75) months. CONCLUSION: In expert hands, salvage ESD was a safe and effective treatment for recurrence of Barrett's neoplasia after RFA treatment.

BACKGROUND & AIMS: Several endoscopic methods have been proposed for the treatment of large biliary stones. We assessed the comparative efficacy of these treatments through a network meta-analysis. METHODS: Nineteen randomized controlled trials (2752 patients) comparing different treatments for management of large bile stones (>10 mm) (endoscopic sphincterotomy, balloon sphincteroplasty, sphincterotomy followed by endoscopic papillary large balloon dilation [S+EPLBD], mechanical lithotripsy, single-operator cholangioscopy [SOC]) with each other were identified. Study outcomes were the success rate of stone removal and the incidence of adverse events. We performed pairwise and network meta-analysis for all treatments, and used Grading of Recommendations, Assessment, Development, and Evaluation criteria to appraise the quality of evidence. RESULTS: All treatments except mechanical lithotripsy significantly outperformed sphincterotomy in terms of stone removal rate (risk ratio [RR], 1.03-1.29). SOC was superior to other adjunctive interventions (vs balloon sphincteroplasty [RR, 1.24; 95% CIs, 1.07-1.45], vs S+EPLBD [RR, 1.23; range, 1.06-1.42] and vs mechanical lithotripsy [RR, 1.34; range, 1.14-1.58]). Cholangioscopy ranked the highest in increasing the success rate of stone removal (surface under the cumulative ranking [SUCRA] score, 0.99) followed by S+EPLBD (SUCRA score, 0.68). SOC and S+EPLBD outperformed the other modalities when only studies reporting on stones greater than 15 mm were taken into consideration (SUCRA scores, 0.97 and 0.71, respectively). None of the assessed interventions was significantly different in terms of adverse event rate compared with endoscopic sphincterotomy or with other treatments. Post-ERCP pancreatitis and bleeding were the most frequent adverse events. CONCLUSIONS: Among patients with large bile stones, cholangioscopy represents the most effective method, in particular in patients with larger (>15 mm) stones, whereas S+EPLBD could represent a less expensive and more widely available alternative.

BACKGROUND: Long-term transmural double-pigtail stent (DPS) placement is recommended for patients with disconnected pancreatic duct syndrome (DPDS) and peripancreatic fluid collections (peri-PFCs). The long-term safety and efficacy of indwelling DPSs were evaluated. METHODS: Medical files of patients treated with DPS for DPDS-associated peri-PFC and with a follow-upâ≥â48 months were reviewed. Early (â<â30 days) and late complications of DPS placement were evaluated and the primary endpoint, i.âe., incidence of late complications per 100 patient-years of follow-up, was calculated. Short- and long-term success rates of endoscopic treatment and rate of peri-PFC recurrence were among secondary endpoints. RESULTS: From 2002 to 2014 we identified 116 patients, with mean (SD) follow-up of 80.6 (34.4) months. Among early complications (nâ=â20), 6 occurred peri-interventionally. Late complications (nâ=â17) were mainly pain due to DPS-induced ulcer or erosion (nâ=â10) and 14 of these were treated conservatively or by stent removal; 2 gastro-pancreatico-colo-cutaneous fistulas and 1 persisting bleed required surgical intervention. No DPS-related deaths were recorded. The incidence rate (95â%CI) of late complications was 2.18 (1.27-3.49) per 100 patient-years of follow-up.âShort- and long-term success rates (with 95â%CI) of endoscopic treatment were 97.4â% (94.5â%-100â%) and 94â% (89.6â%-98.3â%), respectively. The peri-PFC recurrence rate was 28â% (20.1â%-35.9â%), and 92.3â% of these occurred within the first 2 years. Stent migration, chronic pancreatitis, and length of stent (>â6âcm) were independently associated with higher rates of peri-PFC recurrence. CONCLUSIONS: Long-term transmural drainage with DPS is a safe and effective treatment for DPDS-associated peri-PFCs. However, about one quarter of peri-PFCs will recur.

BACKGROUND: A forward-viewing linear (FVL) echoendoscope has been developed with the aim of overcoming some of the limitations of standard curved linear-array (CLA) echoendoscopes. There are no existing studies comparing the performance of the two echoendoscopes for endoscopic ultrasound-guided tissue acquisition (EUS-TA) of solid lesions other than subepithelial lesions. METHODS: This was a prospective, multicenter, randomized trial with a noninferiority design comparing FVL vs. CLA echoendoscopes in patients with solid lesions of the gastrointestinal tract or adjacent organs. Primary outcomes were successful identification of the lesion and success of EUS-TA. Secondary outcomes were safety, sensitivity, specificity, and diagnostic accuracy of the two different scopes for EUS-TA. RESULTS: 126 patients with solid lesions were randomly assigned to the CLA group (63 patients) or the FVL group (63 patients). The two groups were homogeneous with no differences in terms of needle type used, mean number of passes, and site of EUS-TA. No differences were observed between the FVL vs. CLA scopes in identification of the lesion (96.8â% vs. 98.4â%; Pâ>â0.99) and technical success of EUS-TA (92.1â% vs. 96.8â%; Pâ=â0.44). No adverse events occurred. Overall, diagnostic accuracy (77.8â% vs. 84.1â%), sensitivity (76.6â% vs. 84.1â%), and specificity (81.3â% vs. 84.2â%) did not differ between the two groups. CONCLUSIONS: Our results strongly suggest that the FVL echoendoscope is noninferior to the CLA scope for the detection and performance of EUS-TA in patients with solid lesions of the gastrointestinal tract and adjacent organs. In addition, the FVL scope has the same diagnostic yield, accuracy, and safety as the CLA scope.

OBJECTIVE: To develop clinical tools assessing the refluxogenic potential of foods and beverages (F&B) consumed by patients with laryngopharyngeal reflux (LPR). METHODS: European experts of the LPR Study group of the Young-Otolaryngologists of the International Federation of Oto-rhino-laryngological societies were invited to identify the components of Western European F&B that would be associated with the development of LPR. Based on the list generated by experts, four authors conducted a systematic review to identify the F&B involved in the development of esophageal sphincter and motility dysfunctions, both mechanisms involved in the development of gastroesophageal reflux disease and LPR. Regarding the F&B components and the characteristics identified as important in the development of reflux, experts developed three rational scores for the assessment of the refluxogenic potential of F&B, a dish, or the overall diet of the patient. RESULTS: Twenty-six European experts participated to the study and identified the following components of F&B as important in the development of LPR: pH; lipid, carbohydrate, protein composition; fiber composition of vegetables; alcohol degree; caffeine/theine composition; and high osmolality of beverage. A total of 72 relevant studies have contributed to identifying the Western European F&B that are highly susceptible to be involved in the development of reflux. The F&B characteristics were considered for developing a Refluxogenic Diet Score (REDS), allowing a categorization of F&B into five categories ranging from 1 (low refluxogenic F&B) to 5 (high refluxogenic F&B). From REDS, experts developed the Refluxogenic Score of a Dish (RESDI) and the Global Refluxogenic Diet Score (GRES), which allow the assessment of the refluxogenic potential of dish and the overall diet of the LPR patient, respectively. CONCLUSION: REDS, RESDI and GRES are proposed as objective scores for assessing the refluxogenic potential of F&B composing a dish or the overall diet of LPR patients. Future studies are needed to study the correlation between these scores and the development of LPR according to impedance-pH study.

OBJECTIVE: To summarise current knowledge about the prevalence, aetiology and management of recalcitrant laryngopharyngeal reflux (LPR) patients-those who do not respond to anti-reflux medical treatment. METHODS: A literature search was conducted following the PRISMA guidelines to identify studies that reported success of anti-reflux medical treatment with emphasis on studies that attempted to be rigorous in defining a population of LPR patients and which subsequently explored the characteristics of non-responder patients (ie aetiology of resistance; differential diagnoses; management and treatment). Three investigators screened publications for eligibility from PubMED, Cochrane Library and Scopus and excluded studies based on predetermined criteria. Design, diagnostic method, exclusion criteria, treatment characteristics, follow-up and quality of outcome assessment were evaluated. RESULTS: Of the 139 articles screened, 45 met the inclusion criteria. The definition of non-responder patients varied substantially from one study to another and often did not include laryngopharyngeal signs. The reported success rate of conventional therapeutic trials ranged from 17% to 87% and depended on diagnostic criteria, treatment scheme, definition of treatment failure and treatment outcomes that varied substantially between studies. The management of non-responders differed between studies with a few differential diagnoses reported. No study considered the profile of reflux (acidic, weakly acid, non-acid or mixed) or addressed personalised treatment with the addition of alginate or magaldrate, low acid diet, or other interventions that have emerging evidence of efficacy. CONCLUSION: To date, there is no standardised management of LPR patients who do not respond to traditional treatment approached. A diagnostic and therapeutic algorithm is proposed to improve the management of these patients. Future studies will be necessary to confirm the efficacy of this algorithm through large cohort studies of non-responder LPR patients. LEVEL OF EVIDENCE: 2a.

The European Society of Gastrointestinal Endoscopy (ESGE) and United European Gastroenterology present a list of key performance measures for endoscopy services. We recommend that these performance measures be adopted by all endoscopy services across Europe. The measures include those related to the leadership, organization, and delivery of the service, as well as those associated with the patient journey. Each measure includes a recommendation for a minimum and target standard for endoscopy services to achieve. We recommend that all stakeholders in endoscopy take note of these ESGE endoscopy services performance measures to accelerate their adoption and implementation. Stakeholders include patients and their advocacy groups; service leaders; staff, including endoscopists; professional societies; payers; and regulators.

For routine EUS-guided sampling of solid masses and lymph nodes (LNs) ESGE recommends 25G or 22G needles (high quality evidence, strong recommendation); fine needle aspiration (FNA) and fine needle biopsy (FNB) needles are equally recommended (high quality evidence, strong recommendation).When the primary aim of sampling is to obtain a core tissue specimen, ESGE suggests using 19G FNA or FNB needles or 22G FNB needles (low quality evidence, weak recommendation).ESGE recommends using 10-mL syringe suction for EUS-guided sampling of solid masses and LNs with 25G or 22G FNA needles (high quality evidence, strong recommendation) and other types of needles (low quality evidence, weak recommendation). ESGE suggests neutralizing residual negative pressure in the needle before withdrawing the needle from the target lesion (moderate quality evidence, weak recommendation).ESGE does not recommend for or against using the needle stylet for EUS-guided sampling of solid masses and LNs with FNA needles (high quality evidence, strong recommendation) and suggests using the needle stylet for EUS-guided sampling with FNB needles (low quality evidence, weak recommendation).ESGE suggests fanning the needle throughout the lesion when sampling solid masses and LNs (moderate quality evidence, weak recommendation).ESGE equally recommends EUS-guided sampling with or without on-site cytologic evaluation (moderate quality evidence, strong recommendation). When on-site cytologic evaluation is unavailable, ESGE suggests performance of three to four needle passes with an FNA needle or two to three passes with an FNB needle (low quality evidence, weak recommendation).For diagnostic sampling of pancreatic cystic lesions without a solid component, ESGE suggests emptying the cyst with a single pass of a 22G or 19G needle (low quality evidence, weak recommendation). For pancreatic cystic lesions with a solid component, ESGE suggests sampling of the solid component using the same technique as in the case of other solid lesions (low quality evidence, weak recommendation).ESGE does not recommend antibiotic prophylaxis for EUS-guided sampling of solid masses or LNs (low quality evidence, strong recommendation), and suggests antibiotic prophylaxis with fluoroquinolones or beta-lactam antibiotics for EUS-guided sampling of cystic lesions (low quality evidence, weak recommendation). ESGE suggests that evaluation of tissue obtained by EUS-guided sampling should include histologic preparations (e.âg., cell blocks and/or formalin-fixed and paraffin-embedded tissue fragments) and should not be limited to smear cytology (low quality evidence, weak recommendation).

OBJECTIVES: To investigate the added value of diffusion-weighted (DW) magnetic resonance (MR) imaging in the detection of infection in pancreatic fluid collections (PFC). METHODS: Forty-patients with PFC requiring endoscopic-transmural drainage underwent conventional-MR and DW-MR imaging (b = 1000 s/mm2) before endoscopy. MR images were divided into two sets (set1, conventional-MR; set2, conventional-MR, DW-MR and ADC maps) and randomized. Two independent readers performed qualitative and quantitative (apparent diffusion coefficient, ADC) image analysis. Bacteriological analysis of PFC content was the gold standard. Non-parametric tests were used for comparisons. Sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV) and accuracy were calculated for the two sets for both readers. Receiver operating characteristic curves (ROC) were drawn to assess quantitative DW-MR imaging diagnostic performance. RESULTS: For both readers, sensitivity, specificity, NPV, PPV and accuracy for infected PFCs were higher for set2 (P > .05). ADC were lower in infected versus non-infected PFCs (P ≤ .031). Minimum ADC cut-off: 1,090×10-3 mm2/s for reader 1 and 1,012×10-3 mm2/s for reader 2 (sensitivity and specificity 67 % and 96 % for both readers). CONCLUSION: Qualitative information provided by DW-MR may help to assess PFCs infection. Infected PFCs show significantly lower ADCs compared to non-infected ones. KEY POINTS: ⢠DW improves MR diagnostic accuracy to detect infection of PFC ⢠Infected PFCs show lower ADC compared to non-infected ones (P < .031) ⢠DW-MR images are easy to interpret especially for non-experienced radiologist.

BACKGROUND AND STUDY AIMS: Diverse endoscopic methods, such as placement of temporary self-expandable stents, have proven effective for the treatment of post-bariatric surgery leaks. However, some patients do not respond to the usual endoscopic treatment. This study tested the efficacy of an alternative treatment strategy based on trans-fistulary drainage with double-pigtail plastic stents. PATIENTS AND METHODS: We performed a retrospective analysis of patients with abdominal collections following bariatric surgery who were treated by trans-fistulary stenting between May 2007 and February 2015. Clinical success was defined as a sustained (>â4 months) clinical resolution (patient discharged from the hospital without antibiotics and able to resume a normal diet) and radiological response. Patient records, radiological images, and the hospital endoscopy database were reviewed. RESULTS: A total of 33 patients (26 women/7 men, mean age 42 years [SD 11.2]) were included. Collections occurred after sleeve gastrectomy (nâ=â28) or after gastric bypass (nâ=â5). Fourteen patients were treated by trans-fistulary stenting as primary treatment, and 19 patients had undergone previous unsuccessful endoscopic treatment. No serious complication occurred during the drainage procedure. Clinical success was achieved in 26 patients (78.8â%). In two successfully treated patients, stents are still in place. Spontaneous stent migration occurred in 12 patients. In 12 patients, the stents were removed, either electively (nâ=â5) or because of complications (ulcerations nâ=â3, upper gastrointestinal symptoms nâ=â3, splenic hematoma nâ=â1). CONCLUSIONS: Trans-fistulary drainage of post-bariatric abdominal collections is safe and associated with high success rates. This technique can be considered in previously untreated patients, when a collection is not properly drained percutaneously, or after failure of other endoscopic treatments.

BACKGROUND AND STUDY AIMS: Paraduodenal pancreatitis is histologically well defined but its epidemiology, natural history, and connection with chronic pancreatitis are not completely understood. The aim of this study was to review the endoscopic and medical management of paraduodenal pancreatitis. PATIENTS AND METHODS: Medical records of all patients with paraduodenal pancreatitis diagnosed by magnetic resonance cholangiopancreatography (MRCP) or endoscopic ultrasonography (EUS) between 1995 and 2010 were retrospectively reviewed. Clinical features, imaging procedures, and treatments were investigated. The primary end point was the rate of clinical success, and the secondary end points were the radiological or endoscopic improvement, complication rate, and overall survival rate. RESULTS: A total of 51 patients were included in the study (88.2â% alcohol abuse; median age 49 years [range 37â-â70]; 50 men). The most frequent symptoms at presentation were pain (nâ=â50; 98.0â%) and weight loss (nâ=â36; 70.6â%). Chronic pancreatitis was present in 36 patients (70.6â%), and 45 patients (88.2â%) had cysts. Other findings included stricture of the pancreatic duct (nâ=â37; 72.5â%), common bile duct (nâ=â29; 56.9â%), and duodenum (nâ=â24; 47.1â%). A total of 39 patients underwent initial endoscopic treatment: cystenterostomy (nâ=â20), pancreatic and/or biliary duct drainage (nâ=â19), and/or duodenal dilation (nâ=â6). For the patients with available follow-up (nâ=â41), 24 patients required repeat endoscopy and 9 patients required surgery after the initial endoscopic management. After a median follow-up of 54 months (range 6â-â156 months), complete clinical success was achieved in 70.7â% of patients, and the overall survival rate was 94.1â%. CONCLUSIONS: This is the largest series concerning the management of paraduodenal pancreatitis using endotherapy as the first-line intervention. Although repeat endoscopic procedures were required in half of the patients, no severe complication was observed and surgical treatment was ultimately needed in less than 25â% of the patients.

BACKGROUND AND OBJECTIVE: The prevalence of Hepatitis Delta Virus (HDV) is underestimated and the assessment of fibrosis is recommended for this infection. We tested the diagnostic impact of an annual screening for HDV serology in Hepatitis B Surface Antigen (HBs Ag) chronic carriers and followed the progression of fibrosis in these patients. METHODS: Between January 2014 and October 2021, we annually tested all chronic HBs Ag-positive patients for HDV antibody (HDV Ab). Each HDV Ab positive patient underwent annually repeated elastometry. Patients with detectable HDV RNA levels (group 1) were compared to those with undetectable HDV RNA (group 2). RESULTS: We identified 610 chronic HBs Ag-positive patients, and repeated screening for HDV Ab was performed in 534 patients. Sixty (11%) patients were HDV Ab positive at baseline and were considered as "coinfected". Seven cases of HDV superinfection were diagnosed through repeated screening. In co-infected patients, cirrhosis was initially diagnosed in 12/60 patients and developed in six patients during follow-up. HDV RNA PCR was performed in 57/67 patients and 27 had detectable levels (group 1). Cumulative incidence of cirrhosis at 7 years was 13.8% (95% CI 0-30) in group 1 and 0 (95% CI 0-0) in group 2 (p = 0.026). CONCLUSION: A systematic screening for HDV in chronic HB Ag carriers revealed a high prevalence of HDV Ab. Repeated serological screening enables the diagnosis of superinfections in asymptomatic patients. Regular assessment of fibrosis using elastometry leads to the identification of incidental cirrhosis in patients with detectable HDV RNA.

CONTEXT: Pancreatic/para-pancreatic tuberculosis is an extremely rare clinical entity even in endemic regions. It can present as a cystic or solid pancreatic mass mimicking pancreatic malignancy. There are no specific imaging criteria and the clinical symptoms remain vague. Therefore, most cases are diagnosed after surgical exploration for presumed pancreatic neoplasia. CASE REPORT: We report five cases of pancreatic tuberculosis each time with a different clinical presentation, in an occidental country setting where the diagnosis was done by EUS guided FNA (EUS-FNA). CONCLUSION: EUS-FNA is a safe and promising technique for the diagnosis of pancreatic/para-pancreatic tuberculosis, avoiding unnecessary surgery.

OBJECTIVE: Helicobacter pylori and human immunodeficiency virus (HIV) are both pandemic infections with variable geographic prevalence rates. H. pylori-HIV co-infection at the regional and sub-regional levels with a perspective on gastric cancer incidence is discussed. DESIGN: Based on PRISMA guidelines, national data for H. pylori, HIV, and H. pylori-HIV co-infection were collected for the general population through December 2019. Joint temporal and geographical data for H. pylori and HIV infections in 48 countries were available and used to generate H. pylori-HIV co-infection estimates by cross-sectional analysis. These data were compared with gastric carcinoma statistics for the same countries. RESULTS: The estimated global prevalence rate of H. pylori-HIV co-infection was 1.7 per 1000 people, representing 12.6 million people. Prevalence according to region was, in decreasing order, sub-Saharan Africa 21.9‱, Eastern Europe/Central Asia 4.3‱, Latin America/Caribbean 2.0 ‱, North America/Western/Southern/Northern Europe 1.1‱, Asia/Pacific 0.8‱, and North Africa/Middle East 0.1 ‱. The incidence and mortality rates for gastric carcinoma were higher in East/Pacific Asia, Southern/Andean Latin America, and Eastern Europe regions, and the incidence appeared to be 1.8-fold greater in H. pylori-HIV-infected people in East Asia. CONCLUSIONS: The population at risk of H. pylori-HIV co-infection is estimated to be 12.6 million people (2015 reference year). The heterogeneity of H. pylori-HIV co-infection across regions and sub-regions does not show a clear association with gastric carcinoma. Other methodological approaches with analytical studies (cohort, case-control) are required to measure the potential effect of H. pylori infection and its treatment on the incidence of gastric carcinoma in the large HIV-H. pylori-positive cohort.
RESUMEN
BACKGROUND: Post-laparoscopic fundoplication (LF) dysphagia occurs in 5%-17% of patients and optimal management remains a topic of expert discussion. We assessed the efficacy and safety of pneumatic dilation (PD) in patients with persistent post-lLF dysphagia. METHODS: Medical files of patients treated with PD for persistent post-fundoplication-associated dysphagia were reviewed. The primary outcome was long-term clinical success. Secondary endpoints were initial clinical success, dysphagia recurrence rate, and PD-related complication incidence. RESULTS: Overall, 46 patients (74% women, 57.9±11.9 years) underwent 74 PD (mean: 1.6±0.8). A 30 mm, 35 mm, and 40 mm balloon was used in 45.9%, 43.2%, and 10.8%, respectively, of dilations. Among 45 patients with available follow-up, the overall long-term success rate of PD was 31/45 (68.9% [55.4-82.4]). Initial clinical success was 36/45 (80% [68.3-91.7]). Dysphagia recurred in 9 patients (25%; 95%CI 10.9-39.1) and 4 of these were effectively treated with a new dilation. Among 14 non-responders to PD, 11 underwent surgery. Four complications (2 perforations, 1 muscularis dilaceration, and 1 peri-procedural bleeding) occurred in 4 patients (incidence: 5.4% [95%CI; 0.3-10.6]) and were treated with partially covered self-expandable esophageal stents andhemostatic clips. CONCLUSIONS: Pneumatic balloon dilation for post-fundoplication-associated symptoms is associated with a satisfactory long-term success rate and acceptable safety profile.

Background and study aims Saliva, bubbles, or mucus can limit gastric mucosal visualization (GMV), increasing the risk of missed lesions such as gastric cancer. Several studies using endoscopy photodocumentation-based scores have reported increased quality of GMV when mucolytic and/or defoaming agents are administered. This single-center, prospective, double-blind, randomized, placebo-controlled trial aimed to evaluate whether simethicone administration could improve GMV. Patients and methods Patients were randomly assigned (1:1) to receive either 200âmg of simethicone (Group A) or placebo (Group B). Two independent endoscopists reviewed the entire video recording from each examination to assess the quality of GMV. The primary outcome was the rate of adequate GMV, defined as the percentage of patients in each group with a video score scaleâ<â7 based on gastric visualization of five gastric landmarks. Secondary outcomes included procedure duration, patient satisfaction, and side effects. Results A total of 110 consecutive outpatients were randomly assigned to one of the two study groups (11 were excluded for various reasons). For the primary endpoint, 32 patients (61.5â%) in group A achieved adequate GMV compared to one of 47 (2.1â%) in group B (odds ratio [95â% confidence interval]: 73.6 [9.4-576.6]; P â<â0.001). Median procedure time did not differ between the groups ( P â=â0.55), and no differences were detected in patient satisfaction ( P â=â0.18) or side effects ( P â=â0.58). No serious adverse events were documented. Conclusions Premedication with simethicone before upper gastrointestinal endoscopy significantly improves the quality of GMV without affecting the duration of the examination, patient satisfaction, and the rate of side effects.
RESUMEN
Background and study aims Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) is an emerging and minimally invasive technique that seems promising for treatment of focal pancreatic and peripancreatic lesions. Our aim was to prospectively evaluate the feasibility, safety, and technical and clinical success of pancreatic and extra-pancreatic EUS-RFA. Patients and methods We prospectively collected clinical and technical data for all patients who underwent EUS-RFA at two Belgian academic centers from June 2018 to February 2022. Feasibility, adverse events (AEs), and follow-up were also assessed. Results Twenty-nine patients were included, accounting for 35 lesions: 10 non-functioning neuroendocrine tumors (29â%), 13 pancreatic insulinomas (37â%), one adenocarcinoma (3â%), and 11 intra-pancreatic and extra-pancreatic metastatic lesions (31â%). Technical success was achieved in 100â% of cases, with a median of three power applications per lesion (interquartile range 2). The majority of patients (59â%) presented no collateral effects, three (10.3â%) developed non-severe acute pancreatitis, and four (14â%) had mild abdominal pain. At 6 months follow-up (nâ=â25), 36â% of patients showed radiological complete response, 16â% presented a significant partial response and 48â% showedâ<â50â% decrease in diameter. At 12 months (nâ=â20), 30â% showed complete necrosis and 15â% >â50â% decrease in diameter. Hypoglycemia related to insulinoma was immediately corrected in all 13 cases, with no recurrence during follow-up. Conclusions EUS-RFA is feasible, safe, and effective for treatment of pancreatic and peripancreatic tumors. Larger and longer multicenter prospective studies are warranted to establish its role in management of focal pancreatic lesions and oligometastatic disease. Symptomatic insulinoma currently represent the best indication.
