RESUMEN
BACKGROUND AND AIMS: Fully covered self-expandable metal stents (FCSEMSs) are widely used in benign upper gastrointestinal (GI) conditions, but stent migration remains a limitation. An over-the-scope clip (OTSC) device (Ovesco Endoscopy) for stent anchoring has been recently developed. The aim of this study was to evaluate the effect of OTSC fixation on SEMS migration rate. METHODS: A retrospective review of consecutive patients who underwent FCSEMS placement for benign upper GI conditions between 1/2011 and 10/2022 at 16 centers. The primary outcome was rate of stent migration. The secondary outcomes were clinical success and adverse events. RESULTS: A total of 311 (no fixation 122, OTSC 94, endoscopic suturing 95) patients underwent 316 stenting procedures. Compared to the no fixation (NF) group (n=49, 39%), the rate of stent migration was significantly lower in the OTSC (SF) (n=16, 17%, p=0.001) and endoscopic suturing (ES) group (n=23, 24%, p=0.01). The rate of stent migration was not different between the SF and ES groups (p=0.2). On multivariate analysis, SF (OR 0.34, CI 0.17-0.70, p<0.01) and ES (OR 0.46, CI 0.23-0.91, p=0.02) were independently associated with decreased risk of stent migration. Compared to the NF group (n=64, 52%), there was a higher rate of clinical success in the SF (n=64, 68%; p=0.03) and ES group (n=66, 69%; p = 0.02). There was no significant difference in the rate of adverse events between the three groups. CONCLUSION: Stent fixation using OTSC is safe and effective at preventing stent migration and may also result in improved clinical response.
RESUMEN
BACKGROUND : There are limited data on the feasibility of endoscopic submucosal dissection (ESD) for superficial esophageal neoplasia (SEN) located at or adjacent to esophageal varices. We aimed to evaluate the outcomes of ESD in these patients. METHODS: This multicenter retrospective study included cirrhotic patients with a history of esophageal varices with SEN located at or adjacent to the esophageal varices who underwent ESD. RESULTS: 23 patients with SEN (median lesion size 30 mm; 16 squamous cell neoplasia and seven Barrett's esophagus-related neoplasia) were included. The majority were Child-Pugh B (57â%) and had small esophageal varices (87â%). En bloc, R0, and curative resections were achieved in 22 (96â%), 21 (91â%), and 19 (83â%) of patients, respectively. Severe intraprocedural bleeding (nâ=â1) and delayed bleeding (nâ=â1) were successfully treated endoscopically. No delayed perforation, hepatic decompensation, or deaths were observed. During a median (interquartile range) follow-up of 36 (22-55) months, one case of local recurrence occurred after noncurative resection. CONCLUSION: ESD is feasible and effective for SEN located at or adjacent to esophageal varices in cirrhotic patients. Albeit, the majority of the esophageal varices in our study were small in size, when expertise is available, ESD should be considered as a viable option for such patients.

BACKGROUND AND AIMS: Large colon polyps removed by EMR can be complicated by delayed bleeding. Prophylactic defect clip closure can reduce post-EMR bleeding. Larger defects can be challenging to close using through-the-scope clips (TTSCs), and proximal defects are difficult to reach using over-the-scope techniques. A novel, through-the-scope suturing (TTSS) device allows direct closure of mucosal defects without scope withdrawal. The goal of this study was to evaluate the rate of delayed bleeding after the closure of large colon polyp EMR sites with TTSS. METHODS: A multicenter retrospective cohort study was performed involving 13 centers. All defect closure by TTSS after EMR of colon polyps ≥2 cm from January 2021 to February 2022 were included. The primary outcome was rate of delayed bleeding. RESULTS: A total of 94 patients (52% female; mean age, 65 years) underwent EMR of predominantly right-sided (n = 62 [66%]) colon polyps (median size, 35 mm; interquartile range, 30-40 mm) followed by defect closure with TTSS during the study period. All defects were successfully closed with TTSS alone (n = 62 [66%]) or with TTSS and TTSCs (n = 32 [34%]), using a median of 1 (interquartile range, 1-1) TTSS system. Delayed bleeding occurred in 3 patients (3.2%), with 2 requiring repeated endoscopic evaluation/treatment (moderate). CONCLUSION: TTSS alone or with TTSCs was effective in achieving complete closure of all post-EMR defects, despite a large lesion size. After TTSS closure with or without adjunctive devices, delayed bleeding was seen in 3.2% of cases. Further prospective studies are needed to validate these findings before wider adoption of TTSS for large polypectomy closure.

BACKGROUND: Complete closure of large mucosal defects following colorectal endoscopic submucosal dissection (ESD) with through-the-scope (TTS) clips is oftentimes not possible. We aimed to report our early experience of using a novel TTS suturing system for the closure of large mucosal defects after colorectal ESD. METHODS: We performed a retrospective multicenter cohort study of consecutive patients who underwent attempted prophylactic defect closure using the TTS suturing system after colorectal ESD. The primary outcome was technical success in achieving complete defect closure, defined as a <â5âmm residual mucosal defect in the closure line using TTS suturing, with or without adjuvant TTS clips. RESULTS: 82 patients with a median defect size of 30 (interquartile range 25-40) mm were included. Technical success was achieved in 92.7â% (nâ=â76): TTS suturing only in 44 patients (53.7â%) and a combination of TTS suturing to approximate the widest segment followed by complete closure with TTS clips in 32 (39.0â%). Incomplete/partial closure, failure of appropriate TTS suture deployment, and the need for over-the-scope salvage closure methods were observed in 7.3â% (nâ=â6). One intraprocedural bleed, one delayed bleed, and three intraprocedural perforations were observed. There were no adverse events related to placement of the TTS suture. CONCLUSION: The TTS suture system is an effective and safe tool for the closure of large mucosal defects after colorectal ESD and is an alternative when complete closure with TTS clips alone is not possible.

BACKGROUND: Endoscopic resection of lesions involving the appendiceal orifice remains a challenge. We aimed to report outcomes with the full-thickness resection device (FTRD) for the resection of appendiceal lesions and identify factors associated with the occurrence of appendicitis. METHODS: This was a retrospective study at 18 tertiary-care centers (USA 12, Canada 1, Europe 5) between November 2016 and August 2020. Consecutive patients who underwent resection of an appendiceal orifice lesion using the FTRD were included. The primary outcome was the rate of R0 resection in neoplastic lesions, defined as negative lateral and deep margins on post-resection histologic evaluation. Secondary outcomes included the rates of: technical success (en bloc resection), clinical success (technical success without need for further surgical intervention), post-resection appendicitis, and polyp recurrence. RESULTS: 66 patients (32 women; mean age 64) underwent resection of colonic lesions involving the appendiceal orifice (mean [standard deviation] size, 14.5 (6.2) mm), with 40 (61â%) being deep, extending into the appendiceal lumen. Technical success was achieved in 59/66 patients (89â%), of which, 56 were found to be neoplastic lesions on post-resection pathology. Clinical success was achieved in 53/66 (80â%). R0 resection was achieved in 52/56 (93â%). Of the 58 patients in whom EFTR was completed who had no prior history of appendectomy, appendicitis was reported in 10 (17â%), with six (60â%) requiring surgical appendectomy. Follow-up colonoscopy was completed in 41 patients, with evidence of recurrence in five (12â%). CONCLUSIONS: The FTRD is a promising non-surgical alternative for resecting appendiceal lesions, but appendicitis occurs in 1/6 cases.

BACKGROUND: Treatment of Zenker's diverticulum has evolved from open surgery to endoscopic techniques, including flexible and rigid endoscopic septotomy, and more recently, peroral endoscopic myotomy (Z-POEM). This study compared the effectiveness of flexible and rigid endoscopic septotomy with that of Z-POEM. METHODS: Consecutive patients who underwent endoscopic septotomy (flexible/rigid) or Z-POEM for Zenker's diverticulum between 1/2016 and 9/2019 were included. Primary outcomes were clinical success (decrease in Dakkak and Bennett dysphagia score toâ≤â1), clinical failure, and clinical recurrence. Secondary outcomes included technical success and rate/severity of adverse events. RESULTS: 245 patients (110 females, mean age 72.63 years, standard deviation [SD] 12.37 years) from 12 centers were included. Z-POEM was the most common management modality (nâ=â119), followed by flexible (nâ=â86) and rigid (nâ=â40) endoscopic septotomy. Clinical success was 92.7â% for Z-POEM, 89.2â% for rigid septotomy, and 86.7â% for flexible septotomy (Pâ=â0.26). Symptoms recurred in 24 patients (15 Z-POEM during a mean follow-up of 282.04 [SD 300.48] days, 6 flexible, 3 rigid [Pâ=â0.47]). Adverse events occurred in 30.0â% rigid septotomy patients, 16.8â% Z-POEM patients, and 2.3â% flexible septotomy patients (Pâ<â0.05). CONCLUSIONS: There was no difference in outcomes between the three treatment approaches for symptomatic Zenker's diverticulum. Rigid endoscopic septotomy was associated with the highest rate of complications, while flexible endoscopic septotomy appeared to be the safest. Recurrence following Z-POEM was similar to flexible and rigid endoscopic septotomy. Prospective studies with long-term follow-up are required.

BACKGROUND AND AIM: Despite widespread adoption and encouraging results seen over the last 5 years, no consensus exists regarding the endoscopic sleeve gastroplasty (ESG) technique, training, or preprocedure and postprocedure management of the patient. The aim of our survey was to assess practice trends and preferences of bariatric endoscopists with respect to ESG. METHODS: Using a digital platform, we conducted a worldwide survey by emailing a link with an electronic questionnaire to 1200 bariatric endoscopists trained to perform endoscopic suturing using the Apollo Overstitch suturing device (Apollo Endosurgery). RESULTS: We received 221 responses that were included in the analysis. Fifty-one responders (36.4%) required 1 to 10 procedures, and 37 (26.4%) needed 11 to 20 procedures to become proficient at ESG. Ninety-six (68.6%) stated that lower body mass index thresholds should be adopted for Asian and Arab patients. There was no consensus on the ideal number of sutures, with 45 (32.1%), 42 (30%), 36 (25.7%), 13 (9.3%), and 4 (2.9%) recommending 4 to 6, 5 to 7, 6 to 8, 7 to 9, and 8 to 12 sutures, respectively. The primary barriers to establishing an endobariatric program were the inability to establish a cash pay model, 77 (95.1%); lack of institutional support, 61 (75.3%); and difficulty in establishing an ambulatory surgical center/hospital to perform ESG, 73 (90.1%). CONCLUSIONS: ESG practice trends remain heterogenous among practitioners in regard to indication, technique, and preprocedure and postprocedure management. Specific ESG guidelines are warranted, and this survey will assist in providing the framework for these guidelines to be written.

Technologic advancements in the field of therapeutic endoscopy have led to the development of minimally invasive techniques to create GI anastomosis without requiring surgery. Examples of the potential clinical applications include bypassing malignant and benign gastric outlet obstruction, providing access to the pancreatobiliary tree in those who have undergone Roux-en-Y gastric bypass, and relieving pancreatobiliary symptoms in afferent loop syndrome. Endoscopic GI anastomosis is less invasive and less expensive than surgical approaches, result in improved outcomes, and therefore are more appealing to patients and providers. The aim of this review is to present the evolution of luminal endoscopic gastroenteric and enteroenteric anastomosis dating back to the first compression devices and to describe the clinical techniques being used today, such as magnets, natural orifice transluminal endoscopic surgery, and EUS-guided techniques. Through continued innovation, endoscopic interventions will rise to the forefront of the therapeutic arsenal available for patients requiring GI anastomosis.

BACKGROUND AND AIMS: Endoscopic sleeve gastroplasty (ESG) has been shown to be effective for inducing weight loss. The efficacy of liraglutide, a glucagon-like peptide-1 agonist, to augment weight loss after ESG is unknown. This study aims to evaluate the efficacy of ESG and liraglutide (ESG-L) compared with ESG alone. METHODS: This was a retrospective study of prospectively collected data from patients undergoing ESG at 3 outpatient clinics in Brazil between November 2017 and July 2018. Liraglutide was offered to all patients 5 months after ESG. Patients who opted to take liraglutide (ESG-L) were matched 1:1 to patients who declined it (ESG). The primary outcome was percent total body weight loss (%TBWL), and percent excess weight loss (%EWL) 7 months after initiation of liraglutide (12 months after ESG). The secondary outcome was change in percent body fat 12 months after ESG. ESG technique and postprocedure follow-up were identical at all 3 sites. RESULTS: Propensity score matching yielded 26 matched pairs. Adjusted comparisons between the 2 groups showed that patients who opted to take liraglutide had a superior mean %TBWL 7 months after initiation of liraglutide (ESG-L) compared with those who declined it (ESG) (24.72% ± 2.12% vs 20.51% ± 1.68%, respectively; P < .001). ESG-L had a statistically greater reduction in percent body fat compared with ESG (7.85% ± 1.26% vs 10.54% ± 1.88%, respectively; P < .001) at 12 months. CONCLUSIONS: Addition of liraglutide at 5 months results in superior weight loss and improved efficacy as demonstrated by decreased body fat 12 months after ESG. Further studies are imperative to determine optimal dose, timing, and duration of liraglutide.

BACKGROUND AND AIMS: Laparoscopic sleeve gastrectomy (LSG) facilitates significant and durable weight loss; however, weight recidivism and need for revisional surgery occur in a subset of patients. Reduction of a dilated LSG using the revisional endoscopic sleeve gastroplasty (R-ESG) approach is an appealing and minimally invasive alternative to surgical revision that is congruent with obesity as a chronic relapsing disease model. In this study, we examine the safety and efficacy of the technique in a large multicenter international cohort. METHODS: Prospectively collected data from 9 centers for 82 consecutive adults who underwent R-ESG for weight regain after LSG using the OverStitch device (Apollo Endosurgery, Austin, Tex, USA) from March 2014 to November 2019 were reviewed. Total body weight loss (TBWL) and adverse events were reported up to 12 months. Univariable logistic regression was used to identify predictors of response at 12 months. RESULTS: Eighty-two adults (92.7% female) experienced 27.9 ± 20.7 kg weight regain from post-LSG nadir weight, prompting R-ESG (mean age, 42.8 ± 10.4 years) at a mean weight of 128.2 ± 57.5 kg. Mean R-ESG procedure duration was 48.3 ± 20.5 minutes, and the median number of sutures used was 4 (interquartile range, 3-4). After R-ESG, TBWL (follow-up %) was 6.6% ± 3.2% at 1 month (81.7%), 10.6% ± 4.4% at 3 months (74.4%), 13.2% ± 10.1% at 6 months (63.4%), and 15.7% ± 7.6% at 12 months (51.2%). In a per-protocol analysis, ≥10% TBWL was achieved by 37 of 51 patients (72.5%) at 6 months and 34 of 42 patients (81.0%) at 12 months; ≥15% TBWL was achieved by 20 of 46 patients (43.5%) at 6 months and 22 of 42 patients (52.4%) at 12 months. Only 1 moderate adverse event occurred in the form of a narrowed gastroesophageal junction, which resolved after a single endoscopic dilation. CONCLUSIONS: R-ESG is a safe and effective means of facilitating weight loss for weight recidivism after LSG, with sustained results at 1 year. R-ESG should be considered before pursuing more-invasive surgical revisional options.

BACKGROUND: The double purse-string pattern (DPSP) of transoral outlet reduction (TORe) should conceivably result in a more robust scaffolding for the gastrojejunal anastomosis (GJA). However, there is a paucity of literature pertaining to post-TORe stenosis as an adverse event. Our aim was to determine the rate of stenosis, its potential predictors, and other complications of DPSP TORe. METHODS: We performed a retrospective analysis of a prospectively maintained database of 129 consecutive patients who underwent DPSP TORe between December 2015 and August 2019. RESULTS: The adverse event rate of TORe was 17.1â% (nâ=â22), with a 13.3â% (nâ=â17) rate of stenosis. Stenosis was not significantly associated with any baseline characteristics. GJA diameter pre- and post-TORe, the difference between these values, and procedure duration were not predictive of stenosis. Of patients who developed stenosis, 10 (58.8â%) responded to endoscopic balloon dilation and 7 (41.2â%) required stent placement. CONCLUSION: As the DPSP technique is a challenging procedure, with high complication rate and limited benefit, it should not be used for TORe.

BACKGROUND : There is heterogeneity regarding the technical aspects of endoscopic sleeve gastroplasty (ESG), such as applying fundal sutures. Our aim was to determine whether ESG with fundal suturing (ESG-FS) affects weight loss and the serious adverse event (SAE) rate when compared with ESG with no fundal suturing (ESG-NFS). METHODS: We conducted a two-center retrospective analysis of 247 patients who underwent ESG with or without fundal suturing. The primary outcome was percentage excess weight loss (%EWL) at 3, 6, and 12 months post-ESG. The secondary outcomes included the SAE rate and procedure duration. RESULTS: At 3, 6, and 12-months, ESG-NFS had a significantly greater mean %EWL compared with ESG-FS (38.4â% [standard deviation (SD) 15.3â%] vs. 31.2â% [SD 13.9â%], Pâ=â0.001; 54.7â% [SD 19.2â%] vs. 37.7â% [SD 17.3â%], Pâ<â0.001; 65.3â% [SD 21.1â%] vs. 40.6â% [SD 23.5â%], Pâ<â0.001, respectively). There was no statistically significant difference in the SAE rates for ESG-NFS (nâ=â2; 2.0â%) and ESG-FS (nâ=â4; 2.6â%; Pâ>â0.99). The mean procedure time was significantly shorter in the ESG-NFS group at 59.1 minutes (SD 32.7) vs. 93.0 minutes (35.5; Pâ<â0.001), and a lower mean number of sutures were used, with 5.7 (SD 1.1) vs. 8.4 (SD 1.6; Pâ<â0.001). CONCLUSION : ESG-NFS demonstrated greater efficacy and shorter procedure duration. Therefore, fundal suturing should not be performed.

BACKGROUND: Zenker's peroral endoscopic myotomy (Z-POEM) is a novel procedure for the management of symptomatic Zenker's diverticulum. This study aims to report the technical feasibility and outcomes of Z-POEM in the management of Zenker's diverticulum after prior failed interventions. METHODS: Patients with persistent or recurrent symptoms after prior endoscopic and/or surgical intervention for Zenker's diverticulum were retrospectively included. The primary outcome was clinical success, defined as complete or near complete resolution of dysphagia (dysphagia score of 0 or 1) without the need for repeat endoscopic or surgical intervention during follow-up. RESULTS: Z-POEM was technically successful in 30/32 patients (93.8â%). Clinical success was achieved in 29/30 patients (96.7â%), and Z-POEM significantly reduced the median (interquartile range [IQR]) dysphagia score of patients from 2 (1â-â2) to 0 (0) (Pâ<â0.001) over a median duration of follow up of 166 days (IQR 39â-â566). Four patients (12.5â%) had adverse events (two inadvertent mucosotomies and two leaks found on post-procedural esophagrams). CONCLUSION: Z-POEM is feasible, safe, and effective in the majority of patients with recurrent symptoms after prior surgical or endoscopic interventions.

BACKGROUND & AIMS: Bariatric surgery is the most successful treatment for obesity. However, many patients avoid surgery due to its perceived invasive nature and fear of complications. Endoscopic sleeve gastroplasty (ESG) is a seemingly less invasive option for patients with obesity. We performed a systematic review and meta-analysis to evaluate the efficacy and safety of ESG in adults. METHODS: We searched MEDLINE, Embase, Web of Science, and Cochrane Library through July 2019. Investigated outcomes included the percent total body weight loss (TBWL), body mass index reduction, percent excess weight loss (EWL), and adverse events. RESULTS: We extracted data from 8 original studies, published from 2016 through 2019, which included a total of 1772 patients. At 6 months, mean TBWL was 15.1% (95% CI, 14.3-16.0), mean decrease in body mass index was 5.65 kg/m2 (95% CI, 5.07-6.22), and mean excess weight loss was 57.7% (95% CI, 52.0-63.4). Weight loss was sustained at 12 months and 18-24 months with a TBWL of 16.5% (95% CI, 15.2-17.8) and 17.2% (95% CI, 14.6-19.7), respectively. The pooled post-ESG rate of severe adverse events was 2.2% (95% CI, 1.6%-3.1%), including pain or nausea requiring hospitalization (n = 18, 1.08%), upper gastrointestinal bleeding (n=9, 0.56%), and peri-gastric leak or fluid collection (n = 8, 0.48%). CONCLUSIONS: In a systematic review and meta-analysis, we found ESG to produce clinically significant weight loss that was reproducible among independent centers and to have a low rate of severe adverse events. ESG appears to be an effective intervention for patients with obesity, although comparative studies and randomized controlled trials are necessary. PROSPERO Identifier: CRD42019121921.

PURPOSE OF REVIEW: Obesity is a chronic relapsing disease that results in cardiovascular disease, diabetes mellitus, and non-alcoholic fatty liver disease. Currently, surgery represents the most effective treatment. However, the advent of minimally invasive endoscopic bariatric therapy (EBT) has shifted the treatment paradigm to less invasive, cost-effective procedures with minimal complications and recovery time that are preferred by patients. In this review, we will describe current and future EBTs, focusing on outcomes and safety. RECENT FINDINGS: The endoscope has provided an incisionless portal into the gastrointestinal tract for placement of space-occupying devices and intraluminal procedures. EBTs are no longer solely manipulating anatomic alterations; instead, they aim to improve metabolic parameters such as glycated hemoglobin, low-density lipoprotein, cholesterol, and hepatic indices by targeting the mucosal layer of the gastrointestinal tract. The endoscope has succeeded in facilitating clinically meaningful weight loss and improvement of metabolic parameters. Future, solutions to the obesity epidemic will likely entail genetic testing, evaluation of the microbiome, and delivery of personalized therapy, utilizing combination endoscopic modalities that change the anatomy and physiology of individual patients, with new targets such as the abnormal metabolic signal.

BACKGROUND: Since July 2015, Lebanon has been experiencing a waste management crisis. Dumpsites in inhabited areas and waste burning have emerged due to the waste accumulation, further adding to the gravity of the situation. However, the association between the crisis and health of the population has not been scientifically reported. METHODS: A comparative cross-sectional study was conducted to assess whether exposure to open dumpsites and waste burning is associated with acute health symptoms. The study sample included 221 male workers between the ages of 18-60 years selected from two areas chosen based on their proximity to a garbage dumpsite and waste burning. 110 workers were exposed to a garbage dumpsite and waste burning, and 111 workers were not. Data were collected via a face-to-face interview using a newly developed validated structured questionnaire. Chi-square tests were used to check for statistically significant differences between exposure and covariates. Multivariable analyses using multiple logistic regression were used to compare health symptoms between exposed and unexposed workers adjusting for potential confounders. RESULTS: The prevalence of acute health symptoms was greater among the exposed workers than the non-exposed workers, including gastrointestinal, respiratory, dermatological and constitutional symptoms. Controlling for confounding variables, such as age, insurance, family support, residence near dumpsite, work site, and smoking, a minimum odds ratio (OR) of 4.30 was obtained when comparing the exposed population to those non-exposed. CONCLUSION: The strong association between improper waste management and physical health calls for immediate attention by the government, stakeholders and community members to find optimal solutions for this waste management crisis and set immediate priority interventions such as regular waste collection, volume reduction and recycling performance improvement. However, the long recall period may have underestimated our results.
