Abstract Background and Aims EUS-guided gastroenterostomy (EUS-GE) is an effective option to palliate symptoms of gastric outlet obstruction (GOO). While the jejunum is conventionally targeted (EUS-GJ), targeting the duodenum (EUS-GD) may offer clinical advantages. Outcomes were compared for EUS-GJ and EUS-GD. Methods Adult patients who underwent EUS-GE for GOO between 2020 and 2024 were included and categorized as an EUS-GD if the stent entered the transverse or ascending duodenum or an EUS-GJ if the stent entered more distally. The primary outcome was clinical success (soft diet tolerance at 7 days). Secondary outcomes included adverse events (AEs), stent misdeployment, and unplanned endoscopic reintervention. Baseline demographic variables and outcomes were compared with statistical significance at p < 0.05. Results Of the 139 included patients (median age 67 years (IQR 61–74); 41% female), 105 underwent EUS-GJ and 34 underwent EUS-GD. Clinical success was 98% for EUS-GJ and 94% for EUS-GD (p = 0.25). The misdeployment rate was 7% for EUS-GJ and 0% for EUS-GD (p = 0.19). The AE rate was 22% for EUS-GJ and 12% for EUS-GD (p = 0.23). There were no significant differences for stent obstruction (EUS-GJ 12% vs. EUS-GD 6%), bleeding (2% vs. 6%), perforation (4% vs. 0%), stent migration (1% vs. 0%), infection (3% vs. 0%), and unplanned reintervention (14% vs. 9%). Conclusion Both EUS-GJ and EUS-GD demonstrate high clinical success with no significant differences in adverse event rates. These data can support intraprocedural decision-making for endoscopists performing EUS-GE.

ABSTRACT Objectives Patients requiring long‐term enteral nutrition or continuous infusion of carbidopa/levodopa can benefit from jejunostomy tube placement. Recently, directly placed percutaneous transgastric jejunal tubes (TGJs) have been used instead of gastrostomy tubes with jejunal extensions (PEG‐Js) for enteral access. We aim to compare patient characteristics and outcomes after placement of TGJs placed via the introducer technique compared to PEG‐Js. Methods We performed a retrospective study of 141 patients (TGJ = 58, PEG‐J = 83) assessed at Mayo Clinic between 2010 and 2024. Patients were identified using a prospectively maintained procedure data registry. Demographic data, patient characteristics, procedural indications, complications, and first‐replacement date were gathered. Statistical analysis included the Wilcoxon rank sum test, chi‐square test, Fisher's exact test, and Kaplan‐Meier estimates. Patients receiving carbidopa/levodopa were excluded from complications analysis due to the carbidopa/levodopa tube's proprietary structure. A p ‐value of <0.05 was set as a threshold for significance. Results Our results demonstrated no difference in cumulative incidence of complications within 1 year for TGJs and PEG‐Js, p ‐value 0.48. Regarding time to first replacement, treating death as a competing risk factor, there was no statistically significant difference in cumulative incidence of replacement within 1 year for TGJs and PEG‐Js, p ‐value 0.389. Conclusions Our study demonstrates that both direct TGJs and PEG‐Js are safe options for long‐term jejunal feeding. More studies are needed to compare endoscopic to radiologically placed percutaneous transgastric jejunal feeding tubes.

ABSTRACT Background Functional lumen imaging probe (FLIP) utility is established in treatment‐naïve achalasia but less clear following lower esophageal sphincter (LES) directed therapy. Methods Achalasia patients with LES directed therapy across three tertiary care centers between 2017 and 2024 with post‐treatment FLIP and timed barium esophagram (TBE) were retrospectively identified. Reduced esophagogastric junction (EGJ) opening was defined by distensibility index (DI) < 2 mm 2 /mmHg and diameter < 12 mm. Abnormal emptying on TBE was defined as column height ≥ 5 cm at 5 min and/or retained tablet. Eckardt scores ≤ 3 defined clinical response. Key Results The study included 222 patients (46% peroral endoscopic myotomy, 46% laparoscopic Heller myotomy, 8% pneumatic dilation) with a median of 1.4 years to post‐treatment TBE/FLIP. Abnormal emptying on TBE was associated with a narrower median EGJ diameter (13.2 vs. 14.8 mm, p = 0.008), a greater frequency of EGJ diameter < 12 mm (36% vs. 21%, p = 0.012), and a smaller change in EGJ diameter (+4.6 vs. +8.6 mm, p = 0.002). Abnormal emptying on TBE occurred more frequently in patients with EGJ DI < 2 mm 2 /mmHg (8.5% vs. 2.6%, p = 0.052), but was not associated with median EGJ DI (4.5 vs. 5.1 mm 2 /mmHg, p = 0.29) nor median change in EGJ DI (+2.9 vs. +3.9 mm 2 /mmHg, p = 0.25). Patients with reduced EGJ DI or EGJ diameter more often had abnormal TBE (37% vs. 22%, p = 0.012). Only the change in DI (+3.8 vs. +1.5 mm 2 /mmHg, p = 0.012) and diameter (+8.2 vs. +1.6 mm, p = 0.002) on FLIP was associated with a clinical response based on Eckardt ≤ 3. Conclusions and Inferences FLIP following achalasia therapy generally correlates with TBE, although discrepant findings are not uncommon. In particular, FLIP EGJ‐diameter has a strong association with esophageal emptying on TBE. Both TBE and FLIP have limited association with clinical response based on Eckardt, with change in DI and diameter on FLIP most strongly associated. Consequently, FLIP as part of multimodal assessment appears useful in the longitudinal follow‐up of treated achalasia.

Summary Introduction Peroral plication of the esophagus (POPE) can reduce sump size and improve symptoms in end-stage achalasia. However, its long-term efficacy and safety are unknown. Methods Patients with end-stage achalasia who underwent POPE at our institution (2016–2024) were identified. Data were abstracted for patient demographics, procedural details, and clinical and radiographic outcomes. Results Twelve patients underwent POPE. The technical success rate was 100%, with mean procedural time of 57 minutes and without adverse events. Symptomatic improvement occurred in 75% of patients (mean follow-up of 15 months), while 86% had radiographic improvement in sump size. Repeat POPE in 6 (50%) patients a mean of 2.6 years after index POPE and a third POPE in four (33%) patients a mean of 3.1 years later was performed, with similar technical success rates and outcomes to the index POPE. Conclusions POPE is a safe and repeatable long-term therapeutic option in end-stage achalasia.

AbstractObjectiveTo compare reflux symptoms, Zenker's diverticulum recurrence, and clinical outcomes in patients with and without a history of hiatal hernia who underwent Zenker's diverticulotomy (ZD).Study DesignSingle institution retrospective review.SettingTertiary care academic hospital.MethodsA retrospective review of patients with and without a history of hiatal hernia who underwent ZD via an open stapler, rigid endoscopic CO2 laser, stapler, or harmonic scalpel technique from January 2006 to December 2020 was performed. Data were abstracted for patient demographics, reflux symptoms, and rates of adverse events and symptomatic recurrence.ResultsA total of 426 patients were included in the study, 97 (22.8%) of which had a history of hiatal hernia. Eleven patients (11.3%) with a history of hiatal hernia had undergone Nissen fundoplication prior to ZD. Patients with a history of hiatal hernia showed less symptomatic improvement postoperatively. Significant differences were noted in the change in the Eating Assessment Tool (EAT‐10) (P < .01) and Reflux Symptom Index (RSI) (P = .03) where patients without a history of hiatal hernia improved more than hiatal hernia patients. Despite these differences in symptom relief, rates of postoperative complications and rates of recurrence did not significantly differ between groups. The median time to recurrence was similar for both groups.ConclusionPatients without a history of hiatal hernia had significantly larger improvements in EAT‐10 and RSI scores compared to patients with a history of hiatal hernia. However, these differences in scores may not represent clinically meaningful differences. There were no significant differences in postoperative adverse events or in recurrence of the Zenker's diverticulum between groups.

Abstract Background and study aims Limited comparative data exist to guide optimal through-the-scope (TTS) clip selection. The aim of this study was to compare the efficacy, retention, and safety of three industry-leading TTS clips on tissue that mimics common clinical scenarios. Methods A survival study involving six domestic pigs was undertaken. Three commonly used clip models were selected: Assurance (STERIS, Mentor, Ohio, United States), Resolution (Boston Scientific, Boston, Massachusetts, United States), and SureClip (Micro-Tech, Ann Arbor, Michigan, United States). To mimic clinical practice, the following scenarios were assessed: (1) normal mucosa; (2) cold snare resection; and (3) hot mucosal resection simulating fibrotic ulcers. Deployment of clips was randomized to target sites. Repeat endoscopy was performed 2 weeks following placement. Endoscopists rated the ease of use of clip placement on a Likert scale of 1 to 5. Results Fifty-four clips (18 Assurance, 18 Resolution, and 18 SureClip) were placed in six pigs. Mucosal healing was noted at all sites on follow up. Overall retention was nine of 18 (50.0%) SureClip, 10 of 18 (55.6%) Assurance, and 13 of 18 (72.2%) Resolution (P=0.369). There was no difference in clip retention on normal and cold snare resection sites; however, clip retention was significantly higher for Resolution clips on fibrotic ulcers (50.0% versus 0% for Assurance and 0% SureClip, P=0.03). No adverse events were reported. Ease of use was equivalent across all models. Conclusions All clips were equivalent in efficacy and safety with successful clip deployment and mucosal healing. Overall retention rate was low for fibrotic tissue, with an improved retention rate observed with Resolution clips.

AbstractObjectiveTo describe the outcomes of patients undergoing open stapler versus transoral rigid and flexible endoscopic therapies for symptomatic Zenker's diverticulum.Study DesignSingle institution retrospective review.SettingTertiary care academic hospital.MethodsWe retrospectively evaluated the outcomes of 424 consecutive patients who underwent Zenker's diverticulotomy via an open stapler, rigid endoscopic CO2 laser, rigid endoscopic stapler, rigid endoscopic harmonic scalpel, or flexible endoscopic technique from January 2006 to December 2020.ResultsA total of 424 patients (173 females, mean age 73.1 ± 11.2 years) from a single institution were included. A total of 142 patients (33%) underwent endoscopic laser treatment, 33 (8%) underwent endoscopic harmonic scalpel, 92 (22%) underwent endoscopic stapler, 70 (17%) underwent flexible endoscopic, and 87 (20%) underwent open stapler. All open and rigid endoscopic procedures and most of the flexible endoscopic procedures (65%) were performed under general anesthesia. The flexible endoscopic group had a higher percentage of procedure‐related perforation, defined as subcutaneous emphysema or contrast leak on imaging (14.3%). The recurrence rates were higher in the harmonic stapler, flexible endoscopic, and endoscopic stapler groups at 18.2%, 17.1%, and 17.4%, respectively, and lower in the open group (1.1%). Length of hospital stay and return to oral intake were similar among groups.ConclusionThe flexible endoscopic technique was associated with the highest rate of procedure‐related perforation, while the endoscopic stapler had the lowest number of procedural complications. Recurrence rates were higher among the harmonic stapler, flexible endoscopic, and endoscopic stapler groups and lower in the endoscopic laser and open groups. Prospective comparative studies with long‐term follow‐up are needed.
