Objective:

To investigate the value of endoscopic duodenal papillary sphincterotomy combined with balloon dilatation in the treatment of duodenal papilloplasty with titanium clip after choledocholithiasis in post-operative complications.

Materials and methods:

One hundred and twenty-five patients (69 males and 56 females) with a median age of 65 (32-81) years were included. The treatment plan was randomly divided into Group A (n = 59) and Group B (n = 66) according to the random number table. Patients in Group A were treated with endoscopic sphincterotomy (EST) combined with endoscopic papillary large balloon dilation (EPLBD), followed by a titanium clip for duodenal papilloplasty and then indwelling nasobiliary drainage, whereas those in Group B were treated with EST combined EPLBD to remove stones and then indwelling nasobiliary drainage.

Results:

In patients with choledocholithiasis or with anatomical changes that make stone extraction difficult, this prospective study attempted to perform duodenal papilloplasty with titanium clips after EST and EPLBD lithotripsy to compare and observe post-operative papillary healing, biliary reflux, and complication rates.

Conclusions:

The use of endoscopic duodenal papilloplasty with a titanium clip can improve biliary reflux after lithotripsy and reduce the incidence of post-operative cholangitis complications.
