Summary
Recurrent cholangitis is common after hepatolithiasis treatment. Risk factors include residual or recurrent stones and common bile duct strictures, while hepatic resection may be protective.
Area of Science:
- Gastroenterology
- Hepatology
- Surgical Oncology
Background:
- Hepatolithiasis is a prevalent condition in East Asia.
- It can lead to severe complications like recurrent cholangitis, biliary stricture, liver cirrhosis, and cholangiocarcinoma.
- Risk factors for cholangitis post-treatment remain poorly understood.
Purpose of the Study:
- To identify risk factors influencing the rate of cholangitis following hepatolithiasis treatment.
- To analyze the impact of various factors on post-treatment cholangitis incidence.
Main Methods:
- A retrospective review of clinical records for 193 newly diagnosed and treated hepatolithiasis patients.
- A mean follow-up period of 56 months (range: 1-242 months).
- Multivariate analysis to determine significant risk factors.
Main Results:
- Cumulative cholangitis rates reached 25.0% at 3 years and 37.0% at 5 years.
- Hepatic resection was associated with a reduced risk of cholangitis (HR=0.28).
- Residual stones (HR=1.77), recurrent stones (HR=4.02), and strictures in the common hepatic or bile duct were significantly associated with increased cholangitis risk.
Conclusions:
- Cholangitis frequently occurs in hepatolithiasis patients with residual/recurrent stones and common hepatic/bile duct strictures.
- Non-hepatic resection treatments were linked to higher cholangitis rates.
- Specific biliary stricture locations significantly impact cholangitis risk.
