Details for simulation set 3

Case Number	Group I
1	Standard myotomy length (6 cm); no EGJ tone; myotomy affected zone walled by mucosa only; contraction type: normal peristalsis
2	Standard myotomy length (6 cm); with an EGJ tone; myotomy affected zone walled by mucosa only; contraction type: normal peristalsis
3	Standard myotomy length (6 cm); with an EGJ tone; myotomy affected zone walled by mucosa and weakened muscle layers (the strength of the muscle fibers were reduced by 99%, but the matrix of the muscle layers were intact at the myotomy site); contraction type: normal peristalsis
4	Short myotomy length (3 cm); no EGJ tone; myotomy affected zone walled by mucosa only; contraction type: normal peristalsis
5	Short myotomy length (3 cm); with an EGJ tone; myotomy affected zone walled by mucosa only; contraction type: normal peristalsis
6	Short myotomy length (3 cm); with an EGJ tone; myotomy affected zone walled by mucosa and weakened muscle layers (the strength of the muscle fibers were reduced by 99% but the matrix of the muscle layers were intact at the myotomy site); contraction type: normal peristalsis
Group II
POEM length: 12 cm; LM intact at the myotomy site while CM fibers were broken, and CM matrix strength reduced 100-fold; with an EGJ tone; contraction type: normal peristalsis

CM, circular muscle; EGJ, esophagogastric junction; LM, longitudinal muscle; POEM, Peroral endoscopic myotomy.
