Abstract

Background: Choledocholithiasis is a common clinical bile duct disease, laparoscopic choledocholithotomy is the main clinical treatment method for choledocholithiasis. However, the recurrence of postoperative stones is a big challenge for patients and doctors.

Aim: To explore the related risk factors of gallstone recurrence after laparoscopic choledocholithotomy, establish and evaluate a clinical prediction model.

Methods: A total of 254 patients who underwent laparoscopic choledocholithotomy in the First Affiliated Hospital of Ningbo University from December 2017 to December 2020 were selected as the research subjects. Clinical data of the patients were collected, and the recurrence of gallstones was recorded based on the postoperative follow-up. The results were analyzed and a clinical prediction model was established.

Results: Postoperative stone recurrence rate was 10.23% (26 patients). Multivariate Logistic regression analysis showed that cholangitis, the diameter of the common bile duct, the diameter of the stone, number of stones, lithotripsy, preoperative total bilirubin, and T tube were risk factors associated with postoperative recurrence (P < 0.05). The clinical prediction model was ln (p/1-p) = -6.853 + 1.347 × cholangitis + 1.535 × choledochal diameter + 2.176 × stone diameter + 1.784 × stone number + 2.242 × lithotripsy + 0.021 × preoperative total bilirubin + 2.185 × T tube.

Conclusion: Cholangitis, the diameter of the common bile duct, the diameter of the stone, number of stones, lithotripsy, preoperative total bilirubin, and T tube are the associated risk factors for postoperative recurrence of gallstone. The prediction model in this study has a good prediction effect, which has a certain reference value for recurrence of gallstone after laparoscopic choledocholithotomy.
