Medicine (Baltimore) 2024; 103:e38970. [PMID: 39121306 PMCID: PMC11315545 DOI: 10.1097/md.0000000000038970] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Accepted: 06/27/2024] [Indexed: 08/11/2024] Open
Abstract
Achalasia, a rare esophageal motility disorder characterized by the inability of the lower esophageal sphincter to relax and loss of esophageal peristalsis, significantly impacts pediatric patient quality of life through symptoms like dysphagia, chest pain, and weight loss. This nationwide retrospective cohort study evaluates the efficacy and safety of peroral endoscopic myotomy (POEM) for pediatric achalasia in Mongolia, contributing to the limited global data on this minimally invasive treatment in children. Conducted between February 2020 and March 2022 at 2 tertiary centers, the study included symptomatic achalasia patients, treatment-naive or those with unsatisfactory outcomes from previous esophageal dilations. The POEM procedure was assessed for its impact on esophageal structure and function, symptom severity via the Eckardt score, and procedure-related safety, with outcomes measured at baseline, 3 days, and 12 months post-procedure. The study demonstrated notable post-procedure improvements across all measured outcomes: abnormal contraction length and esophageal width significantly reduced, underscoring the procedure's effectiveness. More precisely, the integrated relaxation pressure showed a significant improvement from a mean of 26.8 mm Hg (standard deviation [SD], 5.4 mm Hg) pre-procedure to 10.8 mm Hg (SD, 1.1 mm Hg) 12 months (P < .001). Similarly, Eckardt scores, which assess symptom severity, improved significantly from a pre-procedure mean of 7.0 (SD, 1.0) to a substantially lower score post-procedure (P < .001), reflecting enhanced patient quality of life and symptom alleviation. This study underscores POEM's role as an effective, minimally invasive option for pediatric achalasia management within the Mongolian population, offering significant symptomatic relief and improved esophageal function.

Abstract
Per oral endoscopic myotomy (POEM) has emerged as a preferred approach for the treatment of idiopathic achalasia and various esophageal motility disorders, offering a minimally invasive alternative to traditional laparoscopic Heller's myotomy. Over the past decade, POEM has solidified its status as the primary therapeutic choice in these conditions through constant improvements. Its evolution has been marked by continuous progress, driven by the integration of innovative technologies and sophisticated techniques. Notable advancements in the techniques include the advent of shorter myotomies and sling fiber-preserving gastric myotomies. The introduction of novel image-enhanced endoscopic techniques, such as red dichromatic imaging and much safer bipolar devices, promises to enhance safety and reduce the technical demands of the POEM procedure. Furthermore, significant strides have been made in understanding gastroesophageal reflux (GERD) following POEM, enabling the differentiation of "true reflux" from acidification resulting from fermentation through manual pH tracing assessment. This distinction aids in identifying cases necessitating treatment with proton pump inhibitors. Other treatment strategies of post-POEM GERD have expanded to the incorporation of NOTES fundoplication and device-assisted fundoplication if the necessity arises. This comprehensive review delves into recent developments in POEM, encompassing technical variations, the assessment and management of post-POEM reflux, outcomes in special populations, and future prospects. By exploring these facets, we aim to provide a comprehensive overview of the current state of POEM, shedding light on its evolution and the promising directions it is poised to take in the field of third-space endoscopy.

Abstract
INTRODUCTION Pediatric gastrointestinal motility disorders represent some of the most challenging clinical conditions with largely undefined pathogenetic pathways and therefore limited therapeutic options. Herein, we provide an overview of the recent advances in treatment options for these disorders and their clinical impact. AREAS COVERED PubMed and Medline databases were searched for relevant articles related to the treatment of achalasia, esophageal atresia, gastroparesis, PIPO and constipation published between 2017 and 2022. In this article, we review and summarize recent advances in management of gastrointestinal motility disorders in children with a particular focus on emerging therapies as well as novel diagnostic modalities that help guide their application or develop new, more targeted treatments. EXPERT OPINION Gastrointestinal motility disorders represent one of the most challenging conundrums in pediatric age and despite significant advances in investigative tools, the palette of treatment options remain limited. Overall, while pharmacological options have failed to bring a curative solution, recent advances in minimal invasive therapeutic and diagnostic techniques have emerged as potential keys to symptom and quality of life improvement, such as ENDOFLIP, POEM, cine-MRI, fecal microbiota transplantation.

Rafeeqi T, Salimi-Jazi F, Cunningham A, Wall J. The utility of Endoscopic Functional Luminal Imaging (EndoFLIP) in the diagnosis and management of children with achalasia. J Pediatr Surg 2023; 58:639-642. [PMID: 36683001 DOI: 10.1016/j.jpedsurg.2022.12.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Accepted: 12/12/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND Per-oral endoscopic myotomy (POEM) has is an alternative treatment to laparoscopic Heller myotomy for children with achalasia. The EndoFLIP functional luminal imaging system is used to measure esophagogastric junction (EGJ) distensibility pre- and post-POEM. Previous adult studies have established a correlation between obstructive symptoms and Distensibility Index (DI). Here we analyze the utility of EndoFLIP in diagnosis and management of achalasia in the largest study on pediatric POEM patients and hypothesize that DI may aid diagnosis and treatment of pediatric achalasia. METHODS Demographics, preoperative basal and residual pressures measured on manometry, and EndoFLIP measurements pre- and post-POEM were recorded for children that underwent POEM. Pearson correlation coefficient and T-scores were used to assess for correlation between manometry measurements and pre-POEM DI. Linear regression was conducted to analyze the relationship between pre-POEM DI, Eckardt scores, and manometry pressures. RESULTS Of 33 patients that underwent POEM and EndoFLIP since 2014 (21 male, 12 female), the median pre-POEM Eckardt score decreased from 7 to 1 post-POEM. The median basal pressure was 50 ± 25 mmHg, pre-POEM DI was 0.9 (0.8-1.6) mm2/mmHg and the post-POEM DI was 3.8 (3.2-4.4) mm2/mmHg. There was no correlation between DI and basal pressure or residual pressure, though there was a strong negative correlation between Eckardt scores and DI. CONCLUSION The EndoFLIP system is a valuable tool in adult patients in diagnosing achalasia and defining the endpoint of the POEM procedure. We find that there is a role for EndoFLIP in the pediatric population in diagnosis and management of the disease. TYPE OF STUDY & LEVEL OF EVIDENCE Study of diagnostic test; Level IV.

Abstract
Submucosal endoscopy or third-space endoscopy utilizes the potential space between the mucosal and muscularis layers of the gastrointestinal tract to execute therapeutic interventions for various diseases. Over the last decade, endoscopic access to the submucosal space has revolutionized the field of therapeutic endoscopy. Submucosal endoscopy was originally used to perform endoscopic myotomy in patients with achalasia cardia, and its use has grown exponentially since. Currently, submucosal endoscopy is widely used to resect subepithelial tumors and to manage refractory gastroparesis and Zenker's diverticulum. While the utility of submucosal endoscopy has stood the test of time in esophageal motility disorders and subepithelial tumors, its durability remains to be established in conditions such as Zenker's diverticulum and refractory gastroparesis. Other emerging indications for submucosal endoscopy include esophageal epiphrenic diverticulum, Hirschsprung's disease, and esophageal strictures not amenable to conventional endoscopic treatment. The potential of submucosal endoscopy to provide easy and safe access to the mediastinum and peritoneal spaces may open doors to novel indications and rejuvenate the interest of endoscopists in natural orifice transluminal endoscopic surgery in the future. This review focuses on the current spectrum, recent updates, and future direction of submucosal endoscopy in the gastrointestinal tract.

Abstract
Esophageal achalasia is a relatively rare disease in children that has been treated with balloon dilatation, botulinum toxin injection, and Heller myotomy. Peroral endoscopic myotomy (POEM) is another treatment that has been successfully employed to treat adults with achalasia for over a decade and has been increasingly used in children. This State of the Art Review from the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition Endoscopy Committee reviews the current literature in pediatric POEM including the technique, success rate, complications as well as training guidelines. Though there is limited data, POEM in children has shown encouraging success rates and with further study may become the mainstay of pediatric achalasia treatment.
