The introduction of new technologies in endoscopy has been met with uncertainty, skepticism, and lack of standardization or training parameters, particularly when disruptive devices or techniques are involved. The widespread availability of a novel endoscopic suturing device (OverStitch™) for tissue apposition has enabled the development of applications of endoscopic suturing.The American Gastroenterological Association partnered with Apollo Endosurgery to develop a registry to capture in a pragmatic non-randomized study the safety, effectiveness, and durability of endoscopic suturing in approximating tissue in the setting of bariatric revision and fixation of endoprosthetic devices.We highlight the challenges of the adoption of novel techniques by examining the process of developing and executing this multicenter registry to assess real-world use of this endoscopic suturing device. We also present our preliminary data on the safety and effectiveness of the novel device as it is applied in the treatment of obesity.The Prospective Registry for Trans-Orifice Endoscopic Suturing Applications (ES Registry) was an effective Phase 4, postmarketing registry aimed at capturing pragmatic, real-world use of a novel device. These findings serve to solidify the role of endoscopic suturing in clinical practice.

Background and Aims Direct endoscopic necrosectomy (DEN) of walled-off pancreatic necrosis (WOPN) lacks dedicated instruments and requires repetitive and cumbersome procedures. This study evaluated the safety and efficacy of a new powered endoscopic debridement (PED) system designed to simultaneously resect and remove solid debris within WOPN. Methods This was a single-arm, prospective, multicenter, international device trial conducted from November 2018 to August 2019 at 10 sites. Patients with WOPN ≥6 cm and ≤22 cm and with >30% solid debris were enrolled. The primary endpoint was safety through 21 days after the last DEN procedure. Efficacy outcomes included clearance of necrosis, procedural time, adequacy of debridement, number of procedures until resolution, hospital stay duration, and quality of life. Results Thirty patients (mean age, 55 years; 60% men) underwent DEN with no device-related adverse events. Of 30 patients, 15 (50%) achieved complete debridement in 1 session and 20 (67%) achieved complete debridement within 2 or fewer sessions. A median of 1.5 interventions (range, 1-7) were required. Median hospital stay was 10 days (interquartile range, 22). There was an overall reduction of 91% in percent necrosis within WOPN from baseline to follow-up and 85% in collection volume. Baseline WOPN volume was positively correlated with the total number of interventions (ρ = .363, P = .049). Conclusions The new PED system seems to be a safe and effective treatment tool for WOPN, resulting in fewer interventions and lower hospital duration when compared with published data on using conventional instruments. Randomized controlled trials comparing the PED system with conventional DEN are needed. (Clinical trial registration number: NCT03694210 .)

Background: The use of peroral endoscopic myotomy (POEM) for achalasia has a high incidence of post-procedural gastroesophageal reflux (GER). Transoral incisionless fundoplication (TIF) may be an ideal endoscopic treatment. We report our experience with the use of post-POEM TIF. Methods: In this multicenter retrospective study, post-POEM patients with GER who underwent TIF were included. The study end points were: (i) technical success; (ii) safety; (iii) effectiveness (changes in symptoms, scores, proton pump inhibitor [PPI] use, pH studies). Results: 12 patients underwent TIF after POEM, nine of whom had daily symptoms, with 91.7% requiring twice daily (BID) PPIs. Technical success was achieved in all patients. Two adverse events occurred. There were significant decreases in the percentage of patients on BID PPIs (P = 0.03), frequency of daily symptoms (P = 0.03), Reflux Severity Index questionnaire, and GERD Health-related Quality of Life scores (P = 0.03 and P = 0.003; n = 6). pH studies performed in seven of the patients showed a significant reduction in the mean DeMeester score (P = 0.05) and mean percentage acid exposure time (P = 0.04). Conclusion: Our experience suggests that TIF may be effective and safe in treating GER after POEM. Larger prospective trials are needed.

ObjectiveAlthough gastric per-oral endoscopic myotomy (G-POEM) is considered a promising technique for the management of refractory gastroparesis, high-quality evidence is limited. We prospectively investigated the efficacy and safety of G-POEM in unselected patients with refractory gastroparesis.DesignIn five tertiary centres, patients with symptomatic gastroparesis refractory to standard medical therapy and confirmed by impaired gastric emptying were included. The primary endpoint was clinical success, defined as at least one score decrease in Gastroparesis Cardinal Symptom Index (GCSI) with ≥25% decrease in two subscales, at 12 months. GCSI Score and subscales, adverse events (AEs) and 36-Item Short Form questionnaire of quality of life were evaluated at baseline and 1, 3, 6 and 12 months after G-POEM. Gastric emptying study was performed before and 3 months after the procedure.ResultsOf 80 enrolled patients, 75 patients (94%) completed 12-month follow-up. Clinical success at 12 months was 56% (95% CI, 44.8 to 66.7). GCSI Score (including subscales) improved moderately after G-POEM (p2.6 (OR=3.23, p=0.04) and baseline gastric retention >20% at 4 hours (OR=3.65, p=0.03) were independent predictors of clinical success at 12 months, as was early response to G-POEM at 1 month after therapy (OR 8.75, pConclusionG-POEM is a safe procedure, but showed only modest overall effectiveness in the treatment of refractory gastroparesis. Further studies are required to identify the best candidates for G-POEM; unselective use of this procedure should be discouraged.Trial registration numberClinicalTrials.gov Registry NCT02732821.

Background and study aims The coronavirus disease 2019 (COVID-19), and measures taken to mitigate its impact, have profoundly affected the clinical care of gastroenterology patients and the work of endoscopy units. We aimed to describe the clinical care delivered by gastroenterologists and the type of procedures performed during the early to peak period of the pandemic. Methods Endoscopy leaders in the New York region were invited to participate in an electronic survey describing operations and clinical service. Surveys were distributed on April 7, 2020 and responses were collected over the following week. A follow-up survey was distributed on April 20, 2020. Participants were asked to report procedure volumes and patient characteristics, as well protocols for staffing and testing for COVID-19. Results Eleven large academic endoscopy units in the New York City region responded to the survey, representing every major hospital system. COVID patients occupied an average of 54.5 % (18 – 84 %) of hospital beds at the time of survey completion, with 14.5 % (2 %-23 %) of COVID patients requiring intensive care. Endoscopy procedure volume and the number of physicians performing procedures declined by 90 % (66 %-98 %) and 84.5 % (50 %-97 %) respectively following introduction of restricted practice. During this period the most common procedures were EGDs (7.9/unit/week; 88 % for bleeding; the remainder for foreign body and feeding tube placement); ERCPs (5/unit/week; for cholangitis in 67 % and obstructive jaundice in 20 %); Colonoscopies (4/unit/week for bleeding in 77 % or colitis in 23 %) and least common were EUS (3/unit/week for tumor biopsies). Of the sites, 44 % performed pre-procedure COVID testing and the proportion of COVID-positive patients undergoing procedures was 4.6 % in the first 2 weeks and up to 19.6 % in the subsequent 2 weeks. The majority of COVID-positive patients undergoing procedures underwent EGD (30.6 % COVID +) and ERCP (10.2 % COVID +). Conclusions COVID-19 has profoundly impacted the operation of endoscopy units in the New York region. Our data show the impact of a restricted emergency practice on endoscopy volumes and the proportion of expected COVID positive cases during the peak time of the pandemic.

Background and Aims Endoluminal functional luminal imaging probe (EndoFLIP) is an imaging tool that measures the physiologic characteristics of GI sphincters. In this study, we used EndoFLIP to evaluate the association between the pyloric physiologic measurements and the clinical outcomes of gastric peroral endoscopic myotomy (G-POEM) in patients with refractory gastroparesis. Methods Thirty-seven patients from 5 centers who underwent G-POEM for management of refractory gastroparesis and had EndoFLIP measurements were evaluated. Cross-sectional area (CSA), balloon pressure, and the distensibility index (DI) of the pylorus were evaluated by EndoFLIP at 40 mL and 50 mL balloon fills before and after G-POEM. One-year clinical success and change in gastric emptying study 3 months after the G-POEM procedure were compared with the EndoFLIP measurements. Results Clinical success was achieved in 26 (70%) patients. Post–G-POEM CSA and DI were significantly higher in the clinical success group with both 40-mL volume distension (CSA: 89.9 ± 64.8 vs 172.5 ± 71.9 mm2, P =.003; DI: 5.8 ± 4.4 vs 8.8 ± 6.1 mm2/mm Hg, P =.043) and 50-mL volume distention (CSA: 140.1 ± 89.9 vs 237.5 ± 80.3 mm2, P =.003; DI: 5.6 ± 3.3 vs 9.9 ± 6.6 mm2/mm Hg, P =.049). CSA using 40-mL volume distention with an area under the curve of 0.83 yielded a specificity of 91% and a sensitivity of 71% at a cutoff point of 154 mm2. Conclusions Post–G-POEM CSA of the pylorus is associated with clinical success and improvement in a gastric emptying scan after G-POEM. EndoFLIP measurements of the pylorus have the potential to be used as a tool to predict the clinical outcome of G-POEM.

Gastric peroral endoscopic myotomy (G-POEM) has emerged as an effective management approach for patients with refractory gastroparesis. This study aims to comprehensively study the safety of G-POEM and describe the predictive factors of adverse events (AEs) occurrence.This study is a retrospective study involving 13 tertiary care centers (7 USA, 1 South America, 4 Europe, and 1 Asia). Patients who underwent G-POEM for refractory gastroparesis were included. Cases were identified by the occurrence of AEs. For each case, two controls were randomly selected and matched for age (± 10 years), gender, and etiology of gastroparesis.A total of 216 patients underwent G-POEM for gastroparesis. Overall, 31 (14%) AEs were encountered [mild 24 (77%), moderate 5 (16%), and severe 2 (6%)] during the duration of the study. The most common AE was abdominal pain (n = 16), followed by mucosotomy (n = 5) and capnoperitoneum (n = 4), and AEs were most commonly identified within the first 48-h post-procedure 18 (58%). The risk of adverse event occurrence was significantly higher for endoscopists with experience of 20 G-POEM procedures (OR 3.03 [1.03-8.94], p 0.05).G-POEM seems to be a safe intervention for refractory gastroparesis. AEs are most commonly mild and managed conservatively. Longitudinal mucosal incision, use of hook knife, use of clips for mucosal closure and endoscopist's experience with 20 G-POEM procedures is significantly associated with decreased incidence of AEs.

Minimally invasive endoscopic antireflux therapies are critical for bridging the gap between medical and surgical treatments for gastroesophageal reflux disease (GERD). Although multiple endoscopic devices have been developed, perhaps some of the most exciting options that are currently evolving are the full-thickness suturing techniques using widely available and low-cost platforms. Full-thickness endoscopic suturing can allow for a highly durable recreation of the anatomic and functional components of a lower esophageal sphincter, which are deficient in patients with GERD. Proper patient selection, endoscopic hiatal hernia evaluation, and standardized suturing methods are necessary to ensure success of endoscopic suturing for antireflux therapy.

Background Most studies on endoscopic ultrasound (EUS)-guided gastroenterostomy (EUS-GE) for palliation of malignant gastric outlet obstruction (GOO) utilized a 15-mm lumen-apposing metal stent (LAMS). More recently, a 20-mm LAMS has become available. This study aimed to compare rates of technical and clinical success and adverse events (AEs) in patients undergoing EUS-GE using a 20-mm vs. 15-mm LAMS. Methods Patients who underwent EUS-GE with 15-mm or 20-mm LAMS for malignant GOO during the period from January 2018 to October 2020 were included. The primary outcome was clinical success, defined as an increase in the gastric outlet obstruction score (GOOS) by at least 1 point during follow-up. Secondary outcomes were technical success, maximum tolerated diet, re-intervention rate, and rate/severity of AEs. Results 267 patients (mean age 67 years, 43 % women) with malignant GOO from 19 centers underwent EUS-GE. Clinical success rates were similar for the 15-mm and 20-mm stents (89.2 % [95 %CI 84.2 %–94.2 %] vs. 84.1 % [77.4%–90.6 %], respectively). However, a significantly higher proportion of patients in the 20-mm group tolerated a soft solid/complete diet at the end of follow-up (91.2 % [84.4 %–95.7 %] vs. 81.2 % [73.9 %–87.2 %], P = 0.04). Overall, AEs occurred in 33 patients (12.4 % [8.4 %–16.3 %]), with similar rates for 15-mm and 20-mm stents (12.8 % [7.5 %–18.2 %] vs. 11.8 % [6 %–17.6 %]), including incidence of severe/fatal AEs (2 % [0.4 %–5.8 %] vs. 3.4 % [0.9 %–8.4 %]). Conclusions The 20-mm and 15-mm LAMS show similar safety and efficacy for patients undergoing EUS-GE for malignant GOO. The 20-mm LAMS allows a more advanced diet and is, thus preferred for EUS-GE.

Coronavirus disease 2019 (COVID-19) patients may have varying degrees of hyperlipasemia. The aim was to compare outcomes among different levels of hyperlipasemia in patients with COVID-19.This is a retrospective study examining outcomes among hospitalized COVID-19 patients with a lipase3× upper limit of normal (ULN), asymptomatic hyperlipasemia (3× ULN), secondary pancreatitis (typical respiratory COVID-19 symptoms and found to have pancreatitis), and primary pancreatitis (presenting with pancreatitis).Of 11,883 patients admitted with COVID-19, 1560 patients were included: 1155 patients had normal serum lipase (control group), 270 had elevated lipase3× ULN, 46 patients had asymptomatic hyperlipasemia with lipase3× ULN, 57 patients had secondary pancreatitis, and 32 patients had primary pancreatitis. On adjusted multivariate analysis, the elevated lipase3× ULN and asymptomatic hyperlipasemia groups had worse outcomes with higher mortality (odds ratio [OR], 1.6 [95% confidence interval [CI], 1.2-2.2) and 1.1 [95% CI, 0.5-2.3], respectively), higher need for mechanical ventilation (OR, 2.8 [95% CI, 1.2-2.1] and 2.8 [95% CI, 1.5-5.2], respectively), and longer length of stay (OR, 1.5 [95% CI, 1.1-2.0] and 3.16 [95% CI, 1.5-6.5], respectively).Patients with COVID-19 with elevated lipase3× ULN and asymptomatic hyperlipasemia have generally worse outcomes than those with pancreatitis.

Backgrounds Endoscopic ultrasound (EUS)-guided placement of lumen-apposing metal stents (LAMSs) has gained popularity for the treatment of pancreatic walled-off necrosis (WON). We compared the 20-mm and 15-mm LAMSs for the treatment of symptomatic WON in terms of clinical success and adverse events. Methods We conducted a retrospective, case-matched study of 306 adults at 22 tertiary centers from 04/2014 to 10/2018. A total of 102 patients with symptomatic WON who underwent drainage with 20-mm LAMS (cases) and 204 patients who underwent drainage with 15-mm LAMS (controls) were matched by age, sex, and drainage approach. Conditional logistic regression analysis was performed to compare clinical success (resolution of WON on follow-up imaging without reintervention) and adverse events (according to American Society for Gastrointestinal Endoscopy criteria). Results Clinical success was achieved in 92.2 % of patients with 20-mm LAMS and 91.7 % of patients with 15-mm LAMS (odds ratio 0.92; P = 0.91). Patients with 20-mm LAMS underwent fewer direct endoscopic necrosectomy (DEN) sessions (mean 1.3 vs. 2.1; P Conclusions The 20-mm LAMS showed comparable clinical success and safety profile to the 15-mm LAMS, with the need for fewer DEN sessions for WON resolution.

Background Cryoballoon ablation could induce stricture formation to achieve outlet and pouch reduction in patients regaining weight after Roux-en-Y gastric bypass (RYGB). This pilot study aimed to assess technical feasibility and short-term efficacy. Methods A retrospective chart review (January – November 2018) at two academic centers identified patients with weight regain post-RYGB, treated with cryoablation if pouch > 4 cm and/or outlet > 15 mm. Patients were scheduled for surveillance endoscopies at 8 weeks. Results 22 patients presented 10.5 years (SD 4.42) post-RYGB with weight regain of 30.9 kg (SD 13.7). Technical success was 89.5 % for outlet ablation and 93.0 % for pouch ablation. From baseline to 8 weeks, the outlet was reduced from 24.1 mm (95 % confidence interval [CI] 19.8 to 28.5) to 17.1 mm (95 %CI 13.1 to 21.1; P Conclusion Cryoablation appears technically feasible and effective for outlet and/or pouch reduction in the short term.

Background and Aims The novel use of peroral endoscopic myotomy (POEM) in the treatment of Zenker’s diverticulum (ZD) was recently described in case reports. The aim of this study is to report a multicenter experience with the POEM technique in the management of ZD. Methods This is a multicenter international retrospective study involving 10 centers. The Zenker’s POEM technique was performed using principles of submucosal endoscopy. Results Seventy-five patients (73.3 ± 1.2 years, 33 women) were included with a mean Charleson comorbidity index of 4 ± .2. The mean size of ZD was 31.3 ± 1.6 mm (range, 10-89). The overall technical success rate was 97.3% (73/75). There were 2 technical failures because of the inability to locate the septum and failed tunnel creation. Adverse events occurred in 6.7% (5/75): 1 bleed (mild) conservatively managed and 4 perforations (1 severe, 3 moderate). The mean procedure time was 52.4 ± 2.9 minutes, and mean length of hospital stay was 1.8 ± .2 days. Clinical success was achieved in 92% (69/75) with a decrease in mean dysphagia score from 1.96 to .25 (P Conclusions Endoscopic management of ZD using the POEM technique is novel and feasible with promising efficacy and safety results. Long-term follow-up is needed to ensure durability of response. In addition, comparative studies with other treatment modalities are warranted.

Peroral endoscopic myotomy (POEM) offers an effective and a minimally invasive approach for the management of patients with achalasia and is now considered the standard of care at many centres around the world. Despite its excellent outcomes, the high incidence of postoperative GORD remains its major limitation. Unlike laparoscopic Heller myotomy (LHM), no concomitant fundoplication is performed during POEM, which can increase the incidence of GORD and its long-term consequences. Recently, we diagnosed a case of de novo Barrett’s oesophagus (BE) with oesophageal adenocarcinoma in a patient, 4 years after POEM was performed for achalasia, highlighting the possible long-term consequences of postprocedural GORD. Since it was first clinically described,1 POEM has gained worldwide acceptance as an endoscopic technique for the management of achalasia. Despite its well-established efficacy and safety, the development of GORD post-POEM remains a major concern.2 Of particular concern is that up to two-thirds of patients have asymptomatic and unrecognised GORD.3 The effectiveness of our current management and monitoring strategies for GORD following POEM is not well established. In addition, long-term data pertinent to chronic oesophageal acid exposure after POEM are lacking. The following case is of a 69-year-old man who initially presented at the age of 64 with a 15-year history of dysphagia, regurgitation, microaspiration and intermittent chest pain, and high-resolution oesophageal manometry (HREM) was consistent with type III achalasia. Impedance-pH study was negative for underlying gastro-oesophageal reflux (GER), and the patient had no additional pertinent medical, surgical or family history. POEM was performed with a 17 cm oesophageal myotomy and 2 cm gastric myotomy with no adverse events. Postprocedure, the distensibility index increased from a baseline value of 1.7 mm2/mm Hg to 6.3 mm2/mm Hg using the endoluminal functional lumen imaging probe (EndoFLIP), and oesophagram revealed proper lower oesophagus emptying with no …

Background and study aims Surgical gastroenterostomy (SGE) has been the mainstay treatment for gastric outlet obstruction (GOO). The emergence of endoscopic ultrasound-guided gastroenterostomy (EUS-GE) presents a less invasive alternative for palliation of GOO. We conducted a comprehensive review and meta-analysis to compare the effectiveness and safety of EUS-GE compared to SGE. Methods Multiple electronic databases and conference proceedings up to April 2021 were searched to identify studies that reported on safety and effectiveness of EUS-GE in comparison to SGE. Pooled odds ratios (ORs) of technical success, clinical success, adverse events (AE) and recurrence, and pooled standardized mean difference (SMD) of procedure time and post-procedure length of stay (LOS) were calculated. Study heterogeneity was assessed using I 2 and Cochran Q statistics. Results Seven studies including 625 patients (372 EUS-GE and 253 SGE) were included. EUS-GE had lower pooled odds of technical success compared with SGE (OR 0.19, 95 % confidence interval [CI] 0.06–0.60, I 2 0 %). Among the technically successful cases, EUS-GE was superior in terms of clinical success (OR 4.73, 95 % CI 1.83–12.25, I 2 18 %), lower overall AE (OR 0.20, 95 % CI 0.10–0.37, I 2 39 %), and shorter procedure time (SMD –2.4, 95 % CI –4.1, –0.75, I 2 95 %) and post-procedure LOS (SMD –0.49, 95 % CI –0.94, –0.03, I 2 78%). Rates of severe AE (0.89, 95 % CI 0.11–7.36, I 2 67 %) and recurrence (OR 0.49, 95 % CI 0.18–1.38, I 2 49 %) were comparable. Conclusions Our results suggest EUS-GE is a promising alternative to SGE due to its superior clinical success, overall safety, and efficiency. With further evolution EUS-GE could become the intervention of choice in GOO.

Background and AimsCOVID-19 patients may have asymptomatic hyperlipasemia without abdominal imaging findings or abdominal pain. In addition, primary and secondary pancreatitis have been described in COVID-19 patients. There is limited information on how the groups compare in outcomes. The aim is to compare outcomes among these groups.MethodsThis is a retrospective study from 12 hospitals within one healthcare system examining outcomes between hospitalized COVID-19 patients with a lipase 3x ULN), secondary pancreatitis (typical respiratory COVID-19 symptoms and found to have pancreatitis), and primary pancreatitis (presenting with pancreatitis).ResultsOf 11,883 patients admitted with COVID-19, 1,560 patients were included: 1,155 COVID-19 patients with a normal serum lipase (control group), 270 with an elevated lipase ConclusionCOVID-19 patients with an elevated lipase< 3x ULN and asymptomatic hyperlipasemia have generally worse outcomes than those with pancreatitis. This could be attributed to extrapancreatic causes (liver failure, renal failure, enteritis, etc), which may signify a more severe course of clinical disease.

Coronavirus-19 (COVID-19) caused by SARS-CoV-2 has become a global pandemic. Risk of transmission may occur during endoscopy and the goal is to prevent infection among healthcare professionals while providing essential services to patients. Asia was the first continent to have a COVID-19 outbreak, and this position statement of the Asian Pacific Society for Digestive Endoscopy shares our successful experience in maintaining safe and high-quality endoscopy practice at a time when resources are limited. Sixteen experts from key societies of digestive endoscopy in Asia were invited to develop position statements, including patient triage and risk assessment before endoscopy, resource prioritisation and allocation, regular monitoring of personal protective equipment, infection control measures, protective device training and implementation of a strategy for stepwise resumption of endoscopy services after control of the COVID-19 outbreak.

Background and Aims High rates of technical and clinical success were reported for lumen-apposing metal stent (LAMS) placement for peripancreatic fluid collection (PFC) drainage. However, data on the adverse event (AE) rates are heterogeneous. The aim of this study was to evaluate the incidence, severity, management, and risk factors of AEs related to the use of LAMSs for drainage of PFCs in a large cohort of patients. Methods This is a multicenter, international, retrospective review from 15 centers of all patients who underwent placement of LAMSs for the management of PFCs. A nested case-control study was conducted in patients with (case) or without (control) AEs. Results Three hundred thirty-three procedures in 328 patients were performed (5 patients treated with 2 LAMSs). Technical success was achieved in 321 patients (97.9%). Three hundred four patients were finally included in the study (7 excluded for lost to follow-up information; 10 excluded for deaths unrelated to LAMSs). The rate of clinical success was 89.5%. Seventy-nine LAMS-related AEs occurred in 74 of 304 patients (24.3%), after a mean time of 25.3 days (median, 18 days; interquartile range, 6-30) classified as 20 (25.3%) mild, 54 (68.4%) moderate, or 5 (6.3%) severe. On multivariable analysis compared with control subjects, cases were more likely to have walled-off necrosis (WON) versus pancreatic pseudocysts (odds ratio, 2.18; 95% confidence interval, 1.09-4.46; P = .028), whereas cases were less likely to have undergone tract (balloon) dilation (yes vs no; odds ratio, .47; 95% confidence interval, .22-.93; P = .034). Conclusions Data from this large international retrospective study confirm that the use of LAMSs for management of PFCs has excellent technical and good clinical success rates. The rate of AEs, however, is not negligible and should be carefully considered before using these stents for drainage of PFCs and in particular for WON. Further prospective studies are needed to confirm these findings. (Clinical trial registration number: NCT 03544008.)

Background and study aims Acute non-variceal upper gastrointestinal bleeding (UGIB) due to peptic ulcer disease (PUD) remains a common and challenging emergency managed by gastroenterologists. The proper role of endoscopic suturing on the management of PUD-related UGIB is unknown. Patients and methods This is an international case series of patients who underwent endoscopic suturing for bleeding PUD. Primary outcome was rate of immediate hemostasis and rate of early rebleeding (within 72 hours). Secondary outcomes included technical success, delayed rebleeding (> 72 hours), and rate of adverse events (AEs). Results Ten patients (mean age 66.7 years, 30 % female) were included in this study. Nine (90 %) had prior failed endoscopy hemostasis with an average of 1.4 ± 0.7 (range 1 – 3) prior endoscopic sessions. Forrest classification was Ib in 5 (50 %), IIa in 3 (30 %), IIb in 1(10 %), and IIc in 1 (10 %). Mean suturing time was 13.4 ± 5.6 (range 3.5 to 20) minutes. Technical success was 100 %. Rate of immediate hemostasis was 100 % and rate of early rebleeding was 0 %. Mean number of sutures was 1.5 (range, 1 – 4). No AEs were observed. Delayed recurrent bleeding was not observed in any cases after a median of 11 months (range 2 – 56), after endoscopic suturing. Conclusions Oversewing of a bleeding or high-risk ulcer using endoscopic suturing appears to be a safe and effective method for achieving endoscopic hemostasis. It may be considered as rescue endoscopic therapy when primary endoscopic hemostasis fails to control the bleeding or when hemorrhage recurs after successful control of bleeding.
