To investigate the effects of shortening the duration of abstinence on preoperative anesthesia risk and other postoperative recovery of patients with gastroesophageal reflux syndrome.

From January 2019 to December 2019, 176 patients with minimally invasive surgery, hepatobiliary surgery and gallbladder disease combined with gastroesophageal reflux disease were selected for laparoscopic cholecystectomy in Xinjiang Uygur Autonomous Region People's Hospital,the patients in the study were randomly divided into A, B, C and D groups with A random number table according to different abstinence times before surgery,Each group consisted of 44 patients, and the abstinence times of each group were respectively 3 h, 4 h, 5 h and 6 h,preoperative gastric ultrasound was used to evaluate the anesthetic risk of different abstinence times.

Preoperative ultrasound examination of the stomach showed no statistically significant difference between the four groups (all P＞0.05), and they all met the requirements of anesthesia without reflux aspiration. Group A and B were significantly shorter than group C and D (P＜0.05), and the hospitalization expenses of group A was less than group D (P＜0.05). The comparison results of postoperative nausea among the four groups showed that group A and B were significantly less than group C and D (P＜0.05), but there was no statistically significant difference in vomiting between the four groups (P＞0.05).

It is safe and feasible for patients with gallbladder disease combined with gastroesophageal reflux to shorten the time of drinking abstinence before surgery. Ultrasound results show that all of them meet the requirements of anesthesia, which does not increase the risk of anesthesia for patients, can also reduce the time of postoperative infusion, reduce the length of hospital stay, and reduce the economic burden of patients.
