Abstract
Achalasia is a major esophageal motor disorder featured by the altered relaxation of the esophagogastric junction in the absence of effective peristaltic activity. As a consequence of the esophageal outflow obstruction, achalasia patients present with clinical symptoms of dysphagia, chest pain, weight loss, and regurgitation of indigested food. Other less specific symptoms can also present including heartburn, chronic cough, and aspiration pneumonia. The delay in diagnosis, particularly when the presenting symptoms mimic those of gastroesophageal reflux disease, may be as long as several years. The widespread use of high-resolution manometry has permitted earlier detection and uncovered achalasia phenotypes which can have prognostic and therapeutic implications. Other tools have also emerged to help define achalasia severity and which can be used as objective measures of response to therapy including the timed barium esophagogram and the functional lumen imaging probe. Such diagnostic innovations, along with the increased awareness by clinicians and patients due to the availability of alternative therapeutic approaches (laparoscopic and robotic Heller myotomy, and peroral endoscopic myotomy) have radically changed the natural history of the disorder. Herein, we report the most recent advances in the diagnosis, classification, and management of esophageal achalasia and underline the still-grey areas that needs to be addressed by future research to reach the goal of personalizing treatment.

Liu XY, Chen WF, He MJ, Zhong YS, Zhang YQ, Hu JW, Yao LQ, Li QL, Zhou PH. Publication trends of peroral endoscopic myotomy during 2010-2022: a bibliometric analysis. ANNALS OF TRANSLATIONAL MEDICINE 2022; 10:1272. [PMID: 36618796 PMCID: PMC9816838 DOI: 10.21037/atm-22-2469] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Accepted: 10/08/2022] [Indexed: 12/13/2022]
Abstract
Background Peroral endoscopic myotomy (POEM) has been rapidly accepted as a safe and effective therapy for achalasia and other esophageal motility disorders, and has inspired novel submucosal tunneling techniques. This study analyzed the trends in POEM research and compared contributions from different countries, regions, institutions, journals, and authors using bibliometric analysis to predict the trends and potential hotspots in POEM research. Methods Publications concerning POEM from January 1, 2010 to February 25, 2022, were extracted from the Web of Science database. Book chapters, retrieved manuscripts, news, erratum, non-English language publications, and irrelevant publications were excluded. Data, including keywords for each article, were collected, and network analysis was conducted. Microsoft Excel and VOSviewer were used to collect publication data, analyze publication trends, and visualize relevant results. Results A total of 1,853 publications were identified. Gastrointestinal Endoscopy has been the most popular journal in this field (n=383, 20.67%). Research from the United States was the largest contributor to POEM research worldwide and has provided a pivotal influence (n=743), followed by research from China (n=346) and Japan (n=223). Showa University (Japan) was the most active institution in the field of POEM research. In terms of authors, Dr. Inoue published the most papers in the field with the highest average citation number. Keywords were categorized into 5 clusters: management and outcomes, POEM-derived new techniques, diagnosis and classification, comparison with other treatment approaches, and fundoplication and POEM in children. Average appearing years of keywords was calculated. The topics of adverse events, gastroparesis, and gastric POEM (G-POEM) appeared most recently. Conclusions Researchers from the United States, China, and Japan have published the most articles in the field of POEM research, but there was a disparity between the quantity and quality of publications. Research of management and POEM-derived novel techniques were considered potential areas of focus for future research.

Abstract
PURPOSE OF REVIEW This review aims to provide an overview of the current role of per oral endoscopic myotomy (POEM) in the management of primary esophageal motility disorders and treatment of Zenker's diverticulum. RECENT FINDINGS POEM has been shown to be an effective treatment for achalasia. Recent research has suggested that the length of myotomy may be tailored to the disease phenotype and that short myotomy may be equally effective compared to long myotomy. The role of intra-operative EndoFLIP has shown promise as a tool to assess of the adequacy of myotomy. Further research is needed to determine the role of POEM in other esophageal motility disorders and for treatment of Zenker's diverticulum. Per oral endoscopic myotomy has been shown to be an effective and durable treatment option for achalasia with additional potential roles for the treatment of other esophageal motility disorders and Zenker's diverticulum.

Modified Peroral Endoscopic Myotomy Technique for Type II Achalasia: A Multicenter Retrospective Study. Gastroenterol Res Pract 2022; 2022:3424470. [PMID: 35368617 PMCID: PMC8975685 DOI: 10.1155/2022/3424470] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2021] [Revised: 02/11/2022] [Accepted: 03/15/2022] [Indexed: 11/17/2022] Open
Abstract
Aim This retrospective study is aimed at evaluating the outcomes of a modified peroral endoscopic myotomy (POEM) technique in patients with type II achalasia. Methods We performed a modified POEM procedure, which involved a shorter (total myotomy length = 4 cm), full-thickness myotomy, on 31 patients with type II achalasia. Clinical success rates, technical success rates, pre- and postoperative esophageal manometry results, complications, and reflux-related adverse events were evaluated. Results The clinical success (Eckardt score ≤ 3) rates were 100% and 88.9% within 2 years and beyond 2 years postoperatively, respectively. The median lower esophageal sphincter pressures (LESP) decreased from 31.6 (26.7-49.7) mmHg preoperatively to 13.4 (10.5-21.6) and 11.8 (7.4-16.7) mmHg (P < 0.001) at 6 and 12 months postoperatively, respectively. The median integrated relaxation pressure (IRP) decreased from 27.8 (20.6-37.5) mmHg preoperatively to 12.9 (11.3-23.4) and 11.6 (9.6-16.8) mmHg (P < 0.001) at 6 and 12 months after POEM, respectively. Only one case (3.2%) of mucosal injury, four (12.9%) cases of reflux esophagitis, and two (6.5%) cases of gastroesophageal reflux symptoms were reported. Conclusions The modified POEM technique showed excellent outcomes in patients with type II achalasia.
