Selective circular muscle myotomy is designed to avoid gastroesophageal reflux (GER) postoperatively and decrease morbidity during POEM. But one meta-analysis showed that Heller's surgery could keep patients in long-time remission, mainly because of its full-thickness muscle bundle dissection to make sure of persist relaxation of LES. A retrospective study comparing the outcomes of full-thickness and circular muscle myotomy showed no differences in efficacy, GER or adverse events, although the procedural time was shorter in the full thickness myotomy group.\n\nFurther randomized controlled trials are warranted to assess the efficacy and safety of different modified myotomy approaches in POEM for patients with achalasia."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'maximumAge': '70 Years', 'minimumAge': '14 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* diagnosed as achalasia type I or II according to the Chicago Classification Version 4.0, with an Eckardt score \\>3\n* Their age is ≥14years and ≤70 years\n* Able to give written consent\n\nExclusion Criteria:\n\n* undergone previous surgical treatments\n* had contra-indication to general anesthesia\n* previous surgery of the mediastinum, stomach, or esophagus;\n* Pregnant or lactating female\n* type III achalasia\n* current alcohol or drug addiction, mental retardation, severe congenital or acquired coagulopathy (international normalized ratio \\>1.6)\n* hepatic cirrhosis with or without portal hypertension, eosinophilic esophagitis (biopsies were performed at index endoscopy), or confirmed Barrett's esophagus\n* esophageal diverticula or hiatal hernia based on findings from the index barium esophagram, or other conditions that the investigator believed not appropriate for POEM procedure"}, 'identificationModule': {'nctId': 'NCT04578769', 'briefTitle': 'Assessment of Different Modified POEM for Achalasia', 'organization': {'class': 'OTHER', 'fullName': 'Peking Union Medical College Hospital'}, 'officialTitle': 'Comparison Study of Conventional Peroral Endoscopic Myotomy (POEM) and Different Modified Procedures of POEM for Achalasia', 'orgStudyIdInfo': {'id': 'PUMCH-POEM-1'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'conventional myotomy', 'description': 'conventional myotomy for achalasia type I or II', 'interventionNames': ['Procedure: conventional myotomy']}, {'type': 'EXPERIMENTAL', 'label': 'full-thickness myotomy', 'description': 'modified myotomy (full-thickness myotomy) for achalasia type I or II', 'interventionNames': ['Procedure: full-thickness myotomy']}], 'interventions': [{'name': 'conventional myotomy', 'type': 'PROCEDURE', 'otherNames': ['circular myotomy', 'non-tailored myotomy'], 'description': '1.
