Perioperative Management of Morbidly Obese Patients during Major Abdominal Surgery

ABSTRACT

The population with obesity is seeing a steady increase globally. Obesity is known to be associated with morbidity and mortality after major abdominal surgery, and this correlation becomes more prominent in morbidly obese (MO) patients. Accordingly, adequate preoperative evaluation and preparation should be performed with an understanding of the pathophysiological changes associated with the MO. Precise surgery and adequate postoperative management are also mandatory to reduce complications and unplanned readmissions. However, adequate guidelines for the perioperative management of MO patients undergoing major abdominal surgery are lacking. We provide an overview of the pathophysiologic changes and practical guidelines on the perioperative management of major abdominal surgery in MO patients.
