[Abstract]:Objective: To investigate the effect of local hyperoxia on anaerobic bacterial infection in the abdominal cavity of patients with choledocholithiasis complicated with acute cholangitis and choledocholithotomy after laparoscopic choledocholithotomy by oxygen replacement of carbon dioxide pneumoperitoneum. Sixty-eight patients with choledocholithiasis complicated with acute cholangitis were randomly divided into two groups: control group (34 cases) and experimental group (34 cases). Laparoscopic cholecystectomy+common bile duct exploration+T-tube drainage was used in the experimental group,and oxygen was used to replace the residual carbon dioxide in the abdominal cavity three times after operation to keep the local high concentration of oxygen in the abdominal cavity. Blood cell count (WBC), procalcitonin (PCT), C-reactive protein (CRP), preoperative liver function indicators: Alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubi n (TBIL), direct bilirubi n (Conjugated bilirubi n, TBIL) The negative and positive results of anaerobic culture of bile duct in the two groups were recorded. The negative and positive results of anaerobic culture of bile duct in the two groups were recorded 1 and 3 days after operation, and the negative and positive results of anaerobic culture of abdominal drainage fluid in the abdominal drainage tube at 1 and 3 days after operation. The infection index (WBC, PCT, CRP) and liver function at 1 and 3 days after operation were recorded. Indicators (ALT, AST, TBIL, DBIL). And the above data were statistically analyzed. Results: 1. There was no significant difference in sex and age between the control group and the experimental group (P There was no significant difference in WBC between the control group and the experimental group (P 0.05). 3. There was no significant difference in WBC between the control group and the experimental group (P 0.05). There was no significant difference in PCT between the control group and the experimental group (P 0.05). There was significant difference in PCT between preoperative and postoperative day 1, postoperative day 3, preoperative and postoperative day 3 (P 0.05), and the decrease of procalcitonin in experimental group was more than that in control group. 5. There was no significant difference in CRP between preoperative and postoperative day 1 (P 0.05). The difference of CRP between the control group and the experimental group was statistically significant (P 0.05), and the decrease of CRP in the experimental group was more than that in the control group. There was no significant difference in the results of anaerobic culture of bile from T-tube on the third day after operation (P 0.05). There was significant difference in the results of anaerobic culture of bile from abdominal drainage tube on the first day after operation and on the third day after operation (P 0.05). The positive rate of experimental group was significantly lower than that of control group. Conclusion: 1. The positive rate of anaerobic bacteria culture in abdominal drainage fluid can be reduced by providing local hyperoxic environment in abdominal cavity. 2. Oxygen, as a safe gas for abdominal distention, can reduce the inflammatory index after laparoscopic operation. 3. Procalcitonin is whiter in the evaluation of infection after cholelithiasis operation. Cell counts and C reactive protein were sensitive.
