G-POEM is promising method, which is still under investigation as its safety and efficacy has not been established yet. The ideal closure technique in patients undergoing G-POEM needs to be established. Several techniques may be used for endoscopic mucosal closure: endoscopic clips, OTSC (over the scope clips), endo-loop based methods (KING closure) or endoscopic suture.\n\nThe aim of this prospective, open-label study is to compare efficacy and safety of two methods for incision closure in patients who undergo G-POEM: endoscopic clips vs. endoscopic suturing system (OverStitch).', 'detailedDescription': 'Based on principles of NOTES (natural orifice transluminal endoscopic surgery), a mini-invasive therapeutic procedure such as per-oral endoscopic myotomy (POEM) or gastric per-oral endoscopic pyloromyotomy (G-POEM) have been assessed as new modalities for treatment of oesophageal achalasia or refractory gastroparesis. G-POEM is a new and promising method, which is still under investigation as its safety and efficacy has not been established yet. There are several questions, which need to be answered before G-POEM is considered as a standard clinical procedure. These questions concern, among others, efficacy, safety, technical performance etc. Mucosal incision should be endoscopically closed to prevent leakage into the abdominal cavity. Obtaining adequate mucosal closure is one of the most important steps of the procedure and is essential in avoiding major morbidity. The ideal closure technique in patients undergoing G-POEM needs to be established. Several techniques may be used for endoscopic mucosal closure: endoscopic clips, OTSC clips, endo-loop based methods (KING closure) or endoscopic suture. At present, simple closure with endoscopic clips has been the most frequently described method for mucosal closure in patients undergoing G-POEM. However, as gastric mucosa is thicker compared to the esophagus, where clips are used for POEM without any major problems, several authors have described problems during gastric incision closure - it takes a rather longer time, some clips cannot be placed and in some patients, other closure method had to be used. Thus, endoscopic clips may not be an ideal closure method in the stomach. A platform that replicates a principle of surgical suturing is endoscopic suturing system.\n\nThe aim of this prospective, open-label study is to compare efficacy and safety of two methods for incision closure in patients who undergo G-POEM: endoscopic clips vs. endoscopic suturing system (OverStitch).\n\nInvestigators plan to randomize 30-40 patients (15-20 in both arms, ratio 1:1).\n\nThe assigned closure method will be decided by an endoscopist prior to starting closure.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '90 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
