Abstract
BACKGROUND
Bile duct cyst (BDC) is a rare congenital bile duct malformation. The incidence of bile duct malignancy in BDC patients is markedly higher than that in the general population. However, few studies have been conducted on the risk factors for preoperative carcinogenesis in BDC patients.
AIM
To analyze the risk factors associated with preoperative carcinogenesis in BDC patients.
METHODS
The medical records of BDC patients treated at our hospital between January 2012 and December 2018 were retrospectively reviewed. We constructed a database and compared the characteristics of BDC patients with dysplasia and carcinoma against those with benign cysts. The risk factors for preoperative carcinogenesis were identified using univariate and multivariate analyses.
RESULTS
The cohort comprised 109 BDC patients. Ten patients had preoperative dysplasia or adenocarcinoma. Univariate and multivariate analyses showed that gallbladder wall thickness > 0.3 cm [odds ratio (OR), 6.551; 95% confidence interval (CI), 1.351 to 31.763; P = 0.020] and Todani type IV (OR, 7.675; 95%CI, 1.584 to 37.192; P = 0.011) were independent factors associated with preoperative carcinogenesis.
CONCLUSION
BDC is a premalignant condition. Our findings show that gallbladder wall thickness > 0.3 cm and Todani type IV are independent risk factors for preoperative carcinogenesis of BDC. They are therefore useful for deciding on the appropriate treatment strategy, especially in asymptomatic patients.
Core Tip: Bile duct cyst (BDC) is a rare congenital bile duct malformation that is more common in Asian countries. The incidence of bile duct malignancy in BDC patients is 20- to 30-fold higher than that in the general population. However, few studies have been conducted on the risk factors for preoperative carcinogenesis of BDC. The present study retrospectively analyzed 109 BDC patients and found that gallbladder wall thickness > 0.3 cm and Todani type IV were independently associated with preoperative carcinogenesis. The clinical data and long-term follow-up information of ten BDC patients with dysplasia or carcinoma were also presented.
