The impact of the development of POEM on the frequency of Heller Myotomy procedures in the management of achalasia. A statewide analysis.

Our objective with this study is to take a retrospective look at patients with achalasia in the state of Indiana who have undergone either surgical therapy via laparoscopic or open Heller myotomy, or endoscopic therapy with the Per-oral endoscopic myotomy (POEM) procedure. We plan to compare the year-on-year trends between the number of POEM procedures carried out in Indiana (the vast majority of which are carried out at the Indiana University School of Medicine and the number of Heller myotomies (laparoscopic or open) done at various hospitals across Indiana. Our hypothesis is that the increase in POEM procedures over the last eight years has led to a decrease in the number of Heller myotomies and pneumatic dilations done.
