Clinical Study Of Continuous Negative Pressure Irrigation Of Transanal Double-lumen Drainage Tube In Preventing Anastomotic Fistula After Anus-preserving Operation For Ultra-low Rectal Cancer

Objective: Analyze the value of the continuous negative pressure irrigation of transanal double-lumen drainage tube in the prevention of anastomotic fistula after ultra-low rectal cancer surgery clinical application.Methods: The data of 94 patients with anorectal surgery at the Jilin Provincial People’s Hospital from January 2014 to December 2019 were collected,and the age and sex between groups were not statistically significant(p> 0.05).Randomly divided into the observation group and the control group,in which 46 cases of the observation group were placed with a double-lumen drainage tube under negative pressure irrigation for continuous negative pressure washing,and 48 cases of the control group were placed with a conventional rubber drainage tube through the anus and an external drainage bag.Observe and compare the clinical indicators of the two groups of patients,including operation time,intraoperative blood loss,drainage tube placement time,postoperative first exhaust time,hospitalization time,incidence of anastomotic fistula,secondary surgical intervention rate,postoperative distance Complications,etc.,and statistical analysis and comparison.Results: The study showed that the observation group was significantly better than the control group in terms of the drainage tube placement time,postoperative first exhaust time,hospitalization time,and incidence of postoperative anastomotic fistulas,and the differences were statistically significant.There were no significant differences in the operation time,intraoperative blood loss,and long-term postoperative complications.Conclusion: Continuous negative pressure irrigation of transanal double-lumen drainage tube after anus-preserving operation for ultra-low rectal cancer can reduce the incidence of postoperative anastomotic fistula,shorten the length of hospital stay,and reduce the rate of secondary surgical intervention for patients.It has clinical application value.
