A study retrospectively analyzed the intraoperative and postoperative indexes in 132 patients undergoing precise hepatectomy and 52 patients undergoing irregular hepatectomy and concluded that precise hepatectomy was better than irregular hepatectomy for the treatment of hepatolithiasis. Another study compared the surgical data of hilar cholangiocarcinoma in 18 cases with preoperative three-dimensional (3D) reconstruction and 20 patients without preoperative 3D reconstruction and found that 3D visualization could accurately complete the preoperative assessment of hilar cholangiocarcinoma.
In addition, as in PD, biliary variation is one of the important etiologic factors for recurrent pancreatitis, as well as recurrent cholangitis and hepatolithiasis. This is caused by stasis of bile drainage which is usually seen in type 3a branching pattern due to the acute angle between RP and LHD (14).
[7] reported that hepatolithiasis is considered as a cause of sarcomatous cholangiocarcinoma.
Potential risk factors of CCA are parasitic infections (Opisthorchis viverrini and Clonorchis sinensis), bile duct disorders (biliary tract cysts and hepatolithiasis), toxins, complications (diabetes, cirrhosis, and obesity), alcohol consumption, and smoking [1].
Hepatolithiasis is frequently seen in Type IV A choledochal cysts, and is being observed in increasing frequency in the long follow-up.
MRCP shows diagnostic accuracy comparable to that of ERCP in the evaluation of benign and malignant stenosis of the extrahepatic biliary tree [14]; in addition, it demonstrates high diagnostic capability in locating hepatolithiasis and detecting accompanying biliary strictures [15], in the identification of clinical alterations after cholecystectomy [16], in the assessment of normal or pathological changes after biliary surgery (hepatic resection, liver transplantation) [17, 18].
However, the patient did not present cholangiocarcinoma risk factors, including parasitic infections, primary sclerosing cholangitis, biliary-ducts cysts, hepatolithiasis, toxins, or other less-established risk factors such as inflammatory bowel disease, hepatitis C or B, liver cirrhosis, diabetes, obesity, significant alcoholism (>40 g/day), or smoking [1, 9].
In Southeast Asia, intrahepatic cholangiocarcinoma is more frequent than extrahepatic cholangiocarcinoma, for which hepatolithiasis and fluke infestation are common predisposing factors.
The addition of T1-weighted gradient echo in phase images to standard MRCP sequences improves the detection and differentiation of hepatolithiasis and intrahepatic pneumobilia.
