- Consecutive eligible patients will be randomized in a 1:1 ratio to esophagogastric complex only myotomy or standard myotomy groups. Randomization is done according to the computer-generated algorithm. A clinical research coordinator will prepare the sealed randomization envelops and will hand over to the operating endoscopists before the beginning of the procedure. Written informed consent will be obtained from all participants. In this study, the participants and the care-provider assessing the clinical response to the POEM procedure at 3months will be blinded to the allocation.

• To study total procedure time , intra operative adverse effects and duration of hospital stay.
• Severity of oesophagitis
• Presence of GERD symptoms based on GERD questionnaire & Quality of life questionaire post procedure.
