Summary
Brief summary
The investigators propose a multicenter prospective study in patients undergoing either an
elective bariatric procedure or an elective benign procedure, including laparoscopic/open
cholecystectomy, laparoscopic/open hiatus hernia repair, laparoscopic/open inguinal hernia
repair, laparoscopic/open umbilical hernia repair or laparoscopic ventral wall hernia repair.
Perioperative blood ketone and venous blood gas levels will be measured pre-surgery,
post-surgery and on post-operative days until discharge.

Our primary research objective is to clarify the expected perioperative ketone and blood gas
levels in elective bariatric patients who have been on a VLCD and fasting for surgery,
compared to elective surgical patients who have only been fasting prior to surgery.
