Effects of preoperative oral enzyme-hydrolyzed rice flour solution on gastric emptying and insulin resistance in patients undergoing laparoscopic cholecystectomy: a prospective randomized controlled trial

Abstract

The effect of preoperative oral carbohydrates (POC) on insulin resistance (IR) of laparoscopic cholecystectomy (LC) remains debatable. Enzyme-hydrolyzed rice flour (EHR) is a kind of water-soluble micromolecular carbohydrates. This study aimed to investigate the impact of preoperative oral EHR solution on gastric emptying and IR in patients undergoing LC.
