Effects of Malnutrition on Respiratory and Renal Functions in Patients Undergoing Peroral Endoscopic Myotomy (POEM)

The primary purpose of this study is to define mild, medium and severe risk groups for malnutrition by using preoperative albumin values and MUST score in achalasia patients planned for POEM operation, and to determine the relationship of malnutrition/degree as well as demographic characteristics and comorbidities with postoperative respiratory and renal complications.

The secondary aim of this study was to determine persistent respiratory and renal outcome at 3 months after POEM procedure.
