RESUMEN
Background and study aims Gastroesophageal reflux disease (GERD) following peroral endoscopic myotomy (POEM) occurs in 40% to 60% of patients. There are limited data evaluating antireflux surgery or transoral incisionless fundoplication (TIF) for refractory post-POEM GERD. Patients and methods In a single-center prospective cohort study, consecutive patients with medically refractory post-POEM regurgitation and/or GERD treated with TIF or combined laparoscopic hernia repair and TIF (cTIF) were evaluated. Baseline evaluation: GERD-Health Related Quality of Life (GERD-HQRL) and Reflux Symptom Questionnaire 7-day recall (RESQ-7) questionnaires, EGD, high-resolution manometry (HRM), 48-hour pH test off proton pump inhibitors (PPIs) and impedance planimetry of the esophagogastric junction (EGJ) to calculate the diameter distensibility index (EGJ-DI). A PPI was taken twice daily for 2 weeks after TIF and restarted later if required. Patients returned 9 to 12 months after treatment when all preoperative studies were repeated. Quality of life, pH studies and EGJ metrics before and after antireflux surgery were compared. Results Seventeen patients underwent TIF (n=2, 12%) or cTIF (n=15, 88%) a mean 25±15 months after POEM. At follow-up a mean of 9±1 months after TIF/cTIF, patients required less frequent daily PPIs (n=0.001), were more satisfied (P=0.008), had improved GERD-HQRL (P=0.001), less intensity and frequency of GERD (P=0.001) and fewer reflux episodes (P=0.04) by pH testing. There was no change in EGJ-DI, EGJ diameter, integrated relaxation pressure, % total time pH <4, or DeMeester score. Conclusions TIF and cTIF for difficult-to-control post-POEM GERD appear safe, decrease PPI use and reflux episodes, and improve QOL without significant change in IRP, EGJ compliance, diameter or esophageal acid exposure time.
RESUMEN
OBJECTIVES: Endoscopic ultrasound (EUS)-guided injection of cyanoacrylate (CYA) for primary prophylaxis (PP) of gastric varices (GV) is controversial. This study evaluates the safety and efficacy of this intervention. METHODS: Patients treated for PP of GV bleeding by EUS injection of CYA with or without coils were identified. Endoscopic techniques, outcomes, and adverse events (AEs) were reviewed and compared with a group treated for secondary prophylaxis (SP). Patients were followed until: (i) loss to follow-up; (ii) GV bleeding; (iii) interventional radiology or surgery decompression; (iv) liver transplant; or (v) death or comfort care. RESULTS: One hundred and nineteen patients (61 men; mean 59 ± 12 years) underwent EUS for PP (n = 24) or SP (n = 95). The PP group was treated with CYA alone (n = 18) or with coils (n = 4). Eight (33%) mild (n = 6) or moderate (n = 2) AEs and no index GV bleeding occurred during a mean of 6.1 ± 5.9 months follow-up. Repeat EUS in 22 (92%) PP patients showed 7 (32%) residual GVs, which were retreated with CYA alone (n = 6) or with coils (n = 1). Two (29%) mild (n = 1) or moderate (n = 1) AEs occurred after repeat EUS and 1/22 (5%) index GV bleed occurred during a mean 23 ± 25 months follow-up. Compared to the SP group, the PP group had lower Model for End-stage Liver Disease (MELD) score (P = 0.03), fewer GV stigmata (P < 0.001), required less CYA (P = 0.019) during index EUS, and had a longer time between index and surveillance EUS (P = 0.014). The incidence of AEs and GV bleeding between the two groups were similar. CONCLUSION: Posttreatment GV bleeding and AEs are similar following EUS-guided primary and secondary GV prophylaxis.
RESUMEN
BACKGROUND AND AIMS: Chronic narcotic use may cause opioid-induced esophageal dysfunction and associated type III achalasia, hypercontractile esophagus (HE), diffuse esophageal spasm (DES), and esophagogastric junction outflow obstruction (EGJOO). The frequency of opioid use and its impact on peroral endoscopic myotomy (POEM) in these patients is unknown. METHODS: Consecutive patients between April 2017 and September 2021 who underwent POEM for type III achalasia, EGJOO, DES, or HE with ≥6 months follow-up were identified. Baseline evaluation was done with EGD, esophageal high-resolution manometry (HRM), and functional lumen impedance planimetry (FLIP) of the esophagogastric junction (EGJ). Eckardt scores (ESs) were calculated at baseline and follow-up at 6 to 12 months after POEM for opioid users and nonusers. Clinical response was defined as ES ≤3, EGJ distensibility index >2.8 mm2/mm Hg, maximum EGJ diameter >14 mm, and integrated relaxation pressure (IRP) <15 mm Hg. Opioid use before baseline HRM was assessed. RESULTS: One hundred twenty-six patients underwent POEM, and 89 had ≥6 months of follow-up. Daily opioid use was present in 18 of 89 patients (20%). Baseline demographics, FLIP metrics, IRP, distribution of motility disorders, and POEM characteristics were similar between both groups. At 6 to 12 months after POEM, clinical response and frequency of GERD, esophagitis, and proton pump inhibitor use were similar between opioid users and nonusers. Heartburn was more frequent in the opioid group (82.4% vs 38.6%, P = .002). CONCLUSIONS: In this single-center study of 89 patients with type III achalasia, EGJOO, DES, or HE treated with POEM, daily opioid use was present in 20%. Response to POEM and post-POEM GERD were similar between opioid users and nonusers. (Clinical trial registration number: NCT02770859.).

There are limited data on the safety of same-day discharge (SDD) after peroral endoscopic myotomy (POEM). The aim of our study is to assess the frequency and relationship to POEM for emergency department (ED) visits and hospitalizations after SDD in these patients. We retrospectively identified consecutive patients between November 2019 and August 2021 who underwent POEM with SDD and at least 6 months follow-up. Criteria for SDD includes: (1) no serious procedure-related adverse event; (2) post-POEM esophagram without leak; (3) stable vital signs; (4) ability to take liquids orally; (5) pain controlled without IV analgesia; (6) adequate social support; (7) American Society of Anesthesiologists (ASA) class I-III. A causative relationship between POEM and ED visits and hospitalizations was assigned by consensus. Out of 185 POEMs performed, 78 (41.7%, 42M, mean 51±16 years) had SDD. Within 30 days of POEM, 8 ED visits occurred in 7/78 (9%) patients and 2 (25%) were considered related to POEM; hospitalization was required in 3 (38%). After 30 days, 11 ED visits occurred in 10/78 (12.8%) patients and 1 (9%) was considered related to POEM; hospitalization was required in 5 (45%). In this study of consecutive SDD patients after POEM, 3/19 (16%) ED visits and 2/8 (25%) hospitalizations within 6 months were considered related to the procedure. Therefore, eligible patients who follow and fulfill a strict protocol after POEM may be safely discharged the same day.

INTRODUCTION: There are limited data correlating symptoms with reflux episodes during pH studies after peroral endoscopic myotomy. METHODS: Consecutive patients who underwent POEM followed up ≥6 months later by 48-hour ambulatory wireless pH testing off antisecretory therapy were identified. Reflux symptom association was defined as symptom association probability >95%. RESULTS: The most frequent symptoms of heartburn (47.2%), cough (45.1%), and chest pain (39.6%) were associated with a positive reflux symptom association (symptom association probability >95%) in 20.9%, 17.1%, and 19.4%, respectively. DISCUSSION: There is poor correlation between reported symptoms and esophageal acid exposure during pH testing after POEM.

BACKGROUND AND AIMS: Outcomes after peroral endoscopic myotomy (POEM) are assessed clinically by the Eckardt score (ES) or objectively by high-resolution manometry (HRM) and functional lumen imaging probe (FLIP). This study compared HRM and FLIP to evaluate clinical response after POEM. METHODS: This was a single tertiary center retrospective study of consecutive patients who underwent POEM for treatment-naive achalasia and with ≥6 months of follow-up. Baseline and follow-up testing in all patients included ES, HRM, and FLIP of the esophagogastric junction (EGJ). A normal post-POEM (or normalized) EGJ distensibility index (EGJ-DI) >2.8 mm2/mm Hg, maximum EGJ diameter (MxEGJD) ≥14 mm, and integrated relaxation pressure (IRP) <15 mm Hg were compared with a clinical response, defined as ES ≤3. RESULTS: Eighty-seven patients (58% men, mean age 51 ± 17 years) were included. Overall clinical response by ES, IRP, MxEGJD, and EGJ-DI were 97.7%, 86.2%, 75.9%, and 92.0%, respectively. The sensitivity of a normal IRP (87.1% [95% confidence interval {CI}, 78.0-93.4]) was similar to the sensitivity of a normal MxEGJD (75.3% [95% CI, 64.7-84.0], P = .053) and normal EGJ-DI (91.8% [95% CI, 83.8%-96.6%], P = .39) after POEM to predict clinical response. However, the sensitivity of a normal post-POEM EGJ-DI was superior to a normal post-POEM MxEGJD (P = .001) to predict clinical response. There was no difference in the area under the curve of a normal MxEGJD or EGJ-DI to predict a normal IRP (P = .956) after POEM. CONCLUSIONS: Normal FLIP metrics ≥6 months after POEM for achalasia show good to excellent sensitivity but are equivalent to a normalized IRP by HRM to predict clinical response by ESs. FLIP may be used as an alternative to HRM to assess lower esophageal sphincter response to POEM in these patients. (Clinical trial registration number: NCT02770859.).

Background and study aims The aim of this study was to evaluate whether timed barium esophagram within 24 hours post-per-oral endoscopic myotomy (POEM) (TBE-PP) could predict clinical outcomes. Patients and methods This was a single-center retrospective study of prospectively collected data on consecutive patients withâ≥â6-month follow-up who underwent POEM followed by TBE-PP. Esophageal contrast retention 2 minutes after TBE-PP was assessed as Grade 1 (<â10â%), 2 (10â%-49â%), 3 (50â%-89â%) or 4 (>â90â%). Eckardt score, esophagogastroduodenoscopy (EGD), high-resolution manometry (HRM) and function lumen imaging probe (FLIP) of the esophagogastric junction (EGJ) were obtained at baseline. These tests along with pH testing of antisecretory therapy were repeated 6 and 24 months after POEM. Clinical response by Eckardt scoreâ≤â3, EGJ-distensibility index (EGJ-DI) >â2.8âmm 2 /mm Hg, and integrated relaxation pressure (IRP) <â15âmm Hg and incidence of gastroesophageal reflux disease (GERD) were compared by transit time. Results Of 181 patients (58â% male, mean 53â±â17 yr), TBE-PP was classified as Grade 1 in 122 (67.4â%), Grade 2 in 41 (22.7â%), Grade 3 in 14 (7.7â%) and Grade 4 in 4 (2.2â%). At 6 months, overall clinical response by ES (91.7â%), IRP (86.6â%), EGJ-DI (95.7â%) and the diagnosis of GERD (68.6â%) was similar between Grade 1 and Grade 2-4 TBE-PP. At 24 months, Grade 1 had a higher frequency of a normal IRP compared to Grades 2-4 (95.7â% vs. 60â%, P â=â0.021) but overall response by ES (91.2â%), EGJ-DI (92.3â%) and the diagnosis of GERD (74.3â%) were similar. Conclusions Contrast emptying rate by esophagram after POEM has limited utility to predict clinical response or risk of post-procedure GERD.
RESUMEN
BACKGROUND AND AIMS: Gastroparesis (GP) is a multifactorial disease associated with a large burden on the health care systems. Pyloric-directed therapies including gastric peroral endoscopic myotomy (G-POEM) can be effective in improving patient quality of life and symptom severity. We report on the safety and efficacy of G-POEM and its impact on the quality of life of patients managed at a large referral center. METHODS: Consecutive patients with confirmed GP referred for G-POEM due to failure of medical therapy were included. All patients were assessed at baseline and then at 1, 3, 6, and 12 and 24 months after G-POEM using validated symptom and quality of life instruments, including the Gastroparesis Cardinal Symptom Index (GCSI), Patient Assessment of Gastrointestinal Disorders Symptom Severity Index (PAGI-SYM), and 36-Item Short Form Survey (SF-36). Patients were evaluated before and 6 months after the procedure with EGD, 4-hour scintigraphy, and pyloric EndoFLIP. Technical success was defined as the ability to perform full-thickness pyloromyotomy. Clinical response was defined as an improvement of ≥1 point on GCSI. RESULTS: Fifty-two patients (median age, 48 years; range, 25-80 years, 88% female) underwent G-POEM between February 2018 and September 2020 for the following phenotypes: vomiting-predominant (n=30), dyspepsia-predominant (n=16), and regurgitation-predominant (n=6) GP. The technical success rate was 100%. Adverse events were noted in 3 of 52 patients (5.77%), and were all managed successfully endoscopically. Clinical response was achieved in 68%, 58%, and 48% of patients at 1-month, 6-month, and 12-month follow-up (P < .001, P < .001, and P < .01, respectively). When classified by the cause of GP, the clinical response rates were diabetic GP 64% (11 of 17), postsurgical GP 67% (6 of 9), and idiopathic GP 72% (13 of 18). A statistically significant improvement in PAGI-SYM scores was observed at 1, 3, 6, 12, and 24 months, in addition to significant improvement in several domains of SF-36. Mean 4-hour gastric emptying was reduced 6 months after G-POEM (10.2%) compared with baseline (36.5%, P < .001). We report a significant reduction in the number of emergency department visits and days spent in the hospital up to 24 months after G-POEM. CONCLUSIONS: G-POEM appears to be a safe and feasible treatment alternative for refractory GP with significant short-term and mid-term improvements in overall symptoms, quality of life scores, and health care utilization.
