    Background and study aims Epiphrenic diverticula are rare and mainly occur in patients with underlying esophageal motility disorders. The current standard treatment is surgical diverticulectomy often combined by myotomy and is associated with significant adverse event (AE) rates. The aim of this study was to examine the efficacy and safety of peroral endoscopic myotomy in reducing esophageal symptoms in patients with esophageal diverticula. Patients and methods We performed a retrospective cohort study including patients with an esophageal diverticulum who underwent POEM between October 2014 and December 2022. After informed consent, data were extracted from medical records and patients completed a survey by telephone. The primary outcome was treatment success, defined as Eckardt score below 4 with a minimal reduction of 2 points. Results Seventeen patients (mean age 71 years, 41.2 % female) were included. Achalasia was confirmed in 13 patients (13 /17, 76.5 %), Jackhammer esophagus in two patients (2 /17, 11.8 %), diffuse esophageal spasm in one patient (1 /17, 5.9 %) and in one patient no esophageal motility disorder was found (1 /17, 5.9 %). Treatment success was 68.8 % and only one patient (6.3 %) underwent retreatment (pneumatic dilatation). Median Eckardt scores decreased from 7 to 1 after POEM (p < 0.001). Mean size of the diverticula decreased from 3.6 cm to 2.9 cm after POEM (p < 0.001). Clinical admission was one night for all patients. AEs occurred in two patients (11.8 %) which were classified as grade II and IIIa (AGREE classification). Conclusions POEM is effective and safe to treat patients with esophageal diverticula and an underlying esophageal motility disorder

    No full text
    Background: Nocturnal gastroesophageal reflux symptoms have a major impact on sleep quality and are associated with complicated gastroesophageal reflux disease (GERD). We performed a systematic review to assess the data on the effectiveness of the currently available interventions for the treatment of nocturnal reflux symptoms. Methods: We searched PubMed, EMBASE, and the Cochrane Library. All prospective, controlled, and uncontrolled clinical trials in adult patients describing interventions (lifestyle modifications, surgical and pharmacological) for nocturnal gastroesophageal reflux symptoms were assessed for eligibility. A narrative descriptive summary of findings is presented together with summary tables for study characteristics and quality assessment. Key Results: The initial reference search yielded 3067 citations; 66 citations were screened in full text, of which 31 articles were included. Studies on lifestyle modifications include head of bed elevation (n = 5), prolonging dinner-to-bed time (n = 2), and promoting left lateral decubitus position (n = 2). Placebo-controlled clinical trials investigating proton pump inhibitors (PPIs) (n = 11) show success rates ranging from 34.4% to 80.8% in the PPI group versus 10.4%–51.7% in the placebo group. Laparoscopic fundoplication is reserved for severe disease only. There is insufficient evidence for a recommendation on the use of nasal continuous positive airway pressure (nCPAP), hypnotics, baclofen and adding bedtime H2 receptor antagonists for reducing nocturnal reflux. Conclusion Inferences: A sequential treatment strategy, including head of bed elevation, prolonging dinner-to-bed time, promoting left lateral decubitus position and treatment with acid-suppressive medication is recommended for nocturnal gastroesophageal reflux symptoms. Currently, there is insufficient evidence for the use of nCPAP, hypnotics, baclofen and adding bedtime H2 receptor antagonists

    Associations Between Sleep Position and Nocturnal Gastroesophageal Reflux: A Study Using Concurrent Monitoring of Sleep Position and Esophageal pH and Impedance

    INTRODUCTION: The aim of this study was to investigate the effect of spontaneous sleep positions on the occurrence of nocturnal gastroesophageal reflux. METHODS: In patients referred for ambulatory pH-impedance reflux monitoring, the concurrent sleep position was measured using a sleep position measurement device (measuring left, right, supine, and prone positions). RESULTS: Fifty-seven patients were included. We observed a significantly shorter acid exposure time in the left (median 0.0%, P25-P75, 0.0%-3.0%), compared with the right lateral position (median 1.2%, 0.0%-7.5%, P = 0.022) and the supine position (median 0.6%, 0.00%-8.3%, P = 0.022). The esophageal acid clearance time was significantly shorter in the left lateral decubitus position (median 35 seconds, 16-115 seconds), compared with the supine (median 76 seconds, 22-257 seconds, P = 0.030) and right lateral positions (median 90 seconds, 26-250 seconds, P = 0.002). DISCUSSION: The left lateral decubitus position is associated with significantly shorter nocturnal esophageal acid exposure time and faster esophageal acid clearance compared with the supine and right lateral decubitus positions (see visual abstract)

    The effect of sleep positional therapy on nocturnal gastroesophageal reflux measured by esophageal pH-impedance monitoring

    Background & Aims: The aim of the study was to evaluate the effect of an electronic positional therapy wearable device on nocturnal gastroesophageal reflux measured by pH-impedance reflux monitoring. Methods: We performed a single-center, prospective, interventional study in 30 patients with nocturnal reflux symptoms and a nocturnal esophageal acid exposure time (AET) ≥1.5% measured off acid-suppressive medication by ambulatory pH-impedance reflux monitoring. Patients were treated with an electronic positional therapy wearable device for 2 weeks. The device vibrates in the right lateral decubitus position so it conditions patients to avoid that sleep position. After 2 weeks treatment, the pH-impedance study was repeated. Primary outcome was the change in nocturnal AET. Secondary outcomes include change in number of reflux episodes and reflux symptoms. Results: Complete data were available for 27 patients (13 females, mean age 49.8 years). The median nocturnal AET decreased from 6.0% (IQR, 2.3–15.3) to 3.1% (0.1–10.8) after 2 weeks of treatment (p = 0.079). The number of reflux episodes was significantly reduced after 2 weeks of treatment (baseline: 8.0 (3.0–12.3) vs. end: 3.0 (1.0–8.0); p = 0.041). Treatment led to a statistically significant decrease in time spent in right lateral decubitus position (baseline: mean 36.9% ± 15.2% vs. end: 2.7% ± 8.2%; p = <0.001) and an increase in the left lateral decubitus position (baseline 29.2% ± 14.8% vs. end: 63.3% ± 21.9%; p = <0.001). Symptom improvement was reported by 70.4% of the patients. Conclusions: Sleep positional therapy using an electronic wearable device promotes sleeping in the left lateral decubitus position and improves reflux parameters measured by pH-impedance reflux monitoring

    Sleep Positional Therapy for Nocturnal Gastroesophageal Reflux: A Double-Blind, Randomized, Sham-Controlled Trial

    No full text
    Background & Aims: Experimental studies have suggested that sleep position plays a role in the occurrence of nocturnal gastroesophageal reflux and the left lateral decubitus position is most favorable. The aim of this study was to evaluate the effect of a novel electronic sleep positional therapy wearable device on sleep position and nocturnal reflux symptoms. Methods: We performed a double-blind, randomized, sham-controlled trial in patients with nocturnal symptoms of gastroesophageal reflux. Patients were advised to sleep in the left lateral decubitus position and were assigned randomly (1:1) to an electronic sleep positional therapy wearable device, programmed to either produce a vibration when in the right lateral position (intervention) or only during the first 20 minutes (sham). The primary outcome was treatment success, defined as a 50% or more reduction in the nocturnal reflux score. Secondary outcomes included change in sleep position and reflux symptoms. Results: One hundred patients were randomized. In the intention-to-treat analysis, the rate of treatment success was 44% in the intervention group (22 of 50) vs 24% in the sham group (12 of 50) (risk difference, 20%; 95% CI, 1.8%–38.2%; P =.03). Treatment led to a significant avoidance of sleeping in the right lateral decubitus position (intervention 2.2% vs sham 23.5%; P =.000) and increased time sleeping in the left lateral decubitus position (intervention 60.9% vs sham 38.5%; P =.000). More reflux-free nights were observed in the intervention group (intervention 9 nights [interquartile range, 6–11 nights] vs sham 6 nights [interquartile range, 3–9 nights]; P =.01). Conclusions: Sleep positional therapy using an electronic wearable device promotes sleeping in the left lateral decubitus position and effectively alleviates nocturnal reflux symptoms compared with sham treatment (https://www.trialregister.nl, NL8655)
