Objective:To investigate the application value of drainage with a self-made self-releasing stent and primary suture in bile duct exploration. Methods:A total of 198 patients who underwent surgical treatment of common bile duct stones in our hospital from June 2016 to April 2019 were enrolled

and according to the surgical procedure

they were divided into groups A and B. The 97 patients in group A underwent drainage with a self-made self-releasing stent and primary suture

and 101 patients in group B underwent T-tube drainage of the common bile duct. The two groups were compared in terms of general status

time of operation

and postoperative complications.Results:There were no significant differences between groups A and B in general status

time of operation

and intraoperative blood loss（P > 0.05）

but after surgery

group A had a significantly shorter time to first flatus

a significantly shorter length of hospital stay

and significantly lower costs than group B（P < 0.05）. Group A had a significantly lower incidence rate of postoperative complications than group B. Conclusion:Drainage with a self-made self-releasing stent and primary suture have advantages over conventional T-tube drainage in common bile duct exploration and cholecystolithotomy and thus hold promise for clinical application in primary hospitals.
