Abstract:Objective To explore the effect of high glucose solution on gastrointestinal function recovery, inflammatory reaction and complications of colorectal cancer patients after laparoscopic surgery.Methods Sixty-four patients with colorectal cancer underwent laparoscopic surgery from January 2019 to January 2021 were randomly divided into high glucose group and control group, with 32 cases in each group. Colorectal surgery in both groups was performed by doctors in the same group, and 400 mL of 12.5% glucose solution was taken orally in the high glucose group 3 hours before operation. The recovery of gastrointestinal function, perioperative changes of tumor necrosis factor-α (TNF-α), high mobility group protein B1 (HMGB1), fasting plasma glucose (FPG), insulin, endotoxin, homeostatic model assessment of insulin resistance (HOMA-IR) and insulin-like growth factor-I (IGF-I) were compared between the two groups, and the occurrence of postoperative complications was recorded.Results The postoperative exhaust time, first defecation time and hospitalization time in the high glucose group were shorter than those in the control group, gastric tube indwelling rate in the high glucose group was lower than that in the control group, with statistical significance (P < 0.05). The levels of serum TNF-α and HMGB1 in both groups on the first day after operation and the third day after operation were higher than those on the first day before operation. Serum TNF-α and HMGB1 in the high glucose group were lower than those in the control group on the 1st day and 3rd day after operation, and the difference was statistically significant (P < 0.05). The levels of serum FPG, insulin, endotoxin and HOMA-IR in the two groups on the 1st day and 3rd day after operation were higher than those on the 1st day before operation, and IGF-I was lower than that on the 1st day before operation. Serum FPG, insulin, endotoxin and HOMA-IR in the high glucose group were lower than those in the control group on the 1st day and 3rd day after operation, and IGF-I was higher than that in the control group at the same period, with statistical significance (P < 0.05). The incidence of postoperative complications in high glucose group was 12.50%, which was lower than that in control group (34.38%), and the difference was statistically significant (P < 0.05).Conclusion Oral administration of high-glucose solution before laparoscopic radical resection of colorectal cancer can reduce postoperative inflammatory reaction and blood sugar fluctuation, and help to promote the recovery of gastrointestinal function and decrease postoperative complications.
