Abstract
Objective To compare the effectiveness and safety of two different treatment methods for patients with polycystic liver disease using super selective hepatic arterial embolization. Methods This retrospective study enrolled 41 patients with polycystic liver disease treated from June 2008 to June 2016 in the First Medical Center of Chinese PLA General Hospital. The patients underwent transcatheter super-selective hepatic arterial embdization (TAE). There were 5 men and 36 women. The age ranged from 36 to 68 years. The patients were divided into the observation group (n=14) and the control group (n=27). The observation group underwent treatment using an emulsion of iodized oil and bleomycin and N-butyl-2-cyanoacrylate. The control group underwent iodized oil and N-butyl-2-cyanoacrylate. The clinical symptoms, operative complications, volumes of intrahepatic cysts, hepatic parenchyma volumes of pre-TAE and post-TAE at 3, 6 months and every 6 monthly were compared. Results TAE was technically successful in all the patients. The follow-up periods ranged from 24 to 72 months. The clinical symptoms improved remarkably in the observation group at 3 month, 6 months, 12 months, and 24 months, being 92.9% (13/14), 92.9% (13/14), 92.9% (13/14), 92.3% (12/13), respectively. One patient was lost to follow-up 24 months after operation. The clinical symptoms improved remarkably in the control group at 3 month, 6 months, 12 months, and 24 months, being 88.9% (24/27), 85.2% (23/27), 84.6% (22/26), 81.8% (18/22), respectively. One patient was lost to follow-up 12 months after operation and five patients were lost to follow-up 24 months after operation. Compared with preoperative, the abdominal circumference of two groups had decreased, the total volume of intrahepatic cyst and liver decreased at 6 months, 12 months, and 24 months after surgery (P<0.05). Conclusions TAE was a safe and effective treatment for polycystic liver disease. Patients in the observation group had more effective treatment outcomes on follow-up.
