Project description:AimTo elucidate the impact of the coronavirus disease 2019 (COVID-19) on the practice of high-resolution manometry (HRM) and peroral endoscopic myotomy (POEM) in Japan.MethodsWe utilized a large-scale database involving 14 high-volume centers in Japan to investigate changes in the numbers of HRM and POEM procedures performed and outcomes of POEM between 2019 and 2020. A questionnaire survey was also conducted to analyze pandemic-associated changes in the HRM and POEM protocols.ResultsCompared to that in 2019, the number of HRM and POEM procedures decreased by 17.2% (1587-1314) and 20.9% (630-498), respectively. These declines were prominent during the state of emergency from April to May 2020, particularly in pandemic areas. HRM and POEM in nonpandemic areas were relatively unaffected. From 2019 to 2020, there was a 0.4% (254-248) decrease in POEM cases within the prefecture, but the number outside the prefecture decreased by 33.6% (372-247). During the pandemic, the safety and efficacy of POEM were maintained. The implementation of personal protective equipment (PPE) measures varied among facilities, and PPE for POEM was relatively insufficient compared to that for HRM.ConclusionThe COVID-19 pandemic influenced HRM and POEM practices in Japan. It is necessary to establish a sufficient system for HRM and POEM in each hospital as well as countrywide to overcome the effects of the pandemic.

Project description:BackgroundHigh-resolution manometry (HRM) has improved the accuracy of manometry in detecting achalasia and has helped distinguish between clinically relevant subtypes. This study investigated whether HRM metrics correlate with the achalasia symptoms and symptomatic outcomes of peroral esophageal myotomy (POEM).MethodsOf the 30 patients who were enrolled, 25 were treated with POEM, 12 of who underwent HRM after 3 months. All the patients completed the Eckardt score questionnaires, and those who underwent POEM were followed up for about 6 months. Pearson correlation was used to assess the relationship between the HRM metrics and symptoms and outcomes.Key resultsThe integrated relaxation pressure (IRP) score positively correlated with the total Eckardt score, regurgitation score and weight loss score in all the patients, and with the weight loss score in type I achalasia. In 25 patients (10 patients, type I; 15 patients, type II) who underwent POEM, the total Eckardt scores and individual symptom scores significantly decreased after surgery. Changes in the Eckardt scores were similar between type I and type II. Further, the Eckardt scores and weight loss score changes were positively correlated with baseline IRP. Twelve patients (4 patients, type I; 8 patients, type II) underwent HRM again after POEM. IRP changed significantly after POEM, as did the DEP in type II. The IRP changes after POEM were positively correlated with the Eckardt score changes.Conclusions & inferencesIRP is correlated with the symptoms and outcomes of achalasia patients. Thus, HRM is effective for assessing the severity of achalasia and can predict the efficacy of POEM.

Project description:Background/aimsThe motility change after peroral endoscopic myotomy (POEM) in achalasia is currently focused on lower esophageal sphincter (LES). This study aims to investigate the correlation of motility response between distal and proximal esophagus after POEM.MethodsA total of 32 achalasia patients who received POEM and high-resolution manometry (HRM) were included for analysis. Eckardt score was used to assess symptom improvement. HRM was applied for studying motility. Main parameters analyzed were (1) LES: resting pressure (restP), 4-second integrated relaxation pressure; (2) esophageal body (EB): contractile integral of distal segment with myotomy (CI-DM) and proximal segment without myotomy (CI-PNM); and (3) upper esophageal sphincter (UES): relaxation pressure (UES-RP).ResultsThere were 6 type I, 17 type II, and 9 type III achalasia patients included for analysis. (1) Eckardt score, LES tone, CI-DM, CI-PNM and UES-RP were reduced remarkably after POEM (P< 0.001). (2) no significant correlation was noted between LES tone and contractile intergral of EB. (3) a positive linear correlation of CI-DM and CI-PNM changes was detected (P< 0.001). (4) the change of UES-RP was positively correlated with the change of contractile integral of EB (P< 0.001).ConclusionsMyotomy of the distal esophagus would attenuate proximal EB contraction and assist UES relaxation in achalasia patients after POEM.

Project description:Background and aimsGastric peroral endoscopic myotomy (GPOEM) is a promising treatment for refractory gastroparesis. Initially, endoscopists performed GPOEM along the greater curve of the stomach. We, herein, present a novel modification with a lesser curve approach that offers the advantages of shorter tunnel and possibly better myotomy.MethodsThree patients with refractory gastroparesis underwent GPOEM by use of the lesser curve approach. Two of the patients had a prior GPOEM by the traditional greater curve approach. All procedures were performed with the patient under general anesthesia. The specific tools used for incision, dissection, and myotomy are described. The patients were followed up closely, and the gastroparesis cardinal symptom index (GCSI) was calculated before, and 4 weeks after, the procedure.ResultsThe pyloric ring was exposed very well with the lesser curve approach. The mean procedure time was 48 ± 12 minutes. No immediate or late adverse events were observed. All patients had significant improvement in the GCSI 4 weeks after GPOEM, with resolution of gastroparesis symptoms. The mean follow-up time was 6 months.ConclusionThe lesser curve approach to GPOEM provides an excellent exposure to the pyloric ring and can be used as a primary or a salvage technique for the treatment of refractory gastroparesis.

Project description:There is a need for a lower cost manometry system for assessing anorectal function in primary and secondary care settings. We developed an index finger-based system (termed "digital manometry") and tested it in healthy volunteers, patients with chronic constipation, and fecal incontinence. Anorectal pressures were measured in 16 participants with the digital manometry system and a 23-channel high-resolution anorectal manometry system. The results were compared using a Bland-Altman analysis at rest as well as during maximum squeeze and simulated defecation maneuvers. Myoelectric activity of the puborectalis muscle was also quantified simultaneously using the digital manometry system. The limits of agreement between the two methods were -7.1 ± 25.7 mmHg for anal sphincter resting pressure, 0.4 ± 23.0 mmHg for the anal sphincter pressure change during simulated defecation, -37.6 ± 50.9 mmHg for rectal pressure changes during simulated defecation, and -20.6 ± 172.6 mmHg for anal sphincter pressure during the maximum squeeze maneuver. The change in the puborectalis myoelectric activity was proportional to the anal sphincter pressure increment during a maximum squeeze maneuver (slope = 0.6, R2 = 0.4). Digital manometry provided a similar evaluation of anorectal pressures and puborectalis myoelectric activity at an order of magnitude less cost than high-resolution manometry, and with a similar level of patient comfort. Digital Manometry provides a simple, inexpensive, point of service means of assessing anorectal function in patients with chronic constipation and fecal incontinence.

Project description:PurposeDysphagia, vomiting and feeding difficulties are common symptoms, with which children present. Esophageal function testing with high resolution manometry can help in diagnosing and treating these patients. We aim to access the clinical utility of high-resolution manometry of esophagus in symptomatic pediatric patients.MethodsA retrospective chart review was done on all symptomatic patients who underwent esophageal high-resolution manometry between 2010 and 2019 at Sydney Children's Hospital, Australia. Manometry results were categorized based on Chicago classification. Demographic data, indication of procedure, manometric findings, and details of treatment changes were obtained and analyzed.ResultsThere were 62 patients with median age of 10 years (9 months-18 years). The main indication for the procedure was dysphagia (56%). Thirty-two percent of patients had a co-morbid condition, with esophageal atresia accounting for 16%. The majority (77%) of patients had abnormal manometry which included, ineffective esophageal motility in 45.2%. In esophageal atresia cohort, esophageal pressurization was seen in 50%, aperistalsis in 40% and 10% with prior fundoplication had esophago-gastric junction obstruction. Patients with esophago-gastric junction obstruction or achalasia were treated by either pneumatic dilation or Heller's myotomy. Patients with ineffective esophageal motility and rumination were treated with a trial of prokinetics/dietary texture modification and diaphragmatic breathing.ConclusionEsophageal high-resolution manometry has a role in the evaluation of symptomatic pediatric patients. The majority of our patients had abnormal results which led to change in treatments, with either medication, surgery and/or feeding modification with resultant improvement in symptoms.
