Abstract:
Objective To investigate the technique,efficacy,and safety of percutaneous interventional treatments for biliary complications (BC) after liver transplantation (LT).Methods The clinical and imaging data of 127 patients with BC after LT,who received percutaneous interventional treatments in the Third Affiliated Hospital of Sun Yat-sen University from January 2006 to December 2015,were analyzed retrospectively.On the basis of the cholangiographic appearance,patients were classified into 5 groups:biliary leakage group (n =11),anastomotic biliary strictures group (n=28),hilar biliary strictures group (n =30),multifocal biliary strictures group (n =51),and bilomas group (n =7).The modality of interventional treatments was percutanous transhepatic biliary drainage (PTBD),PTBD combined with balloon dilation,PTBD combined with balloon dilation and stent implantation.The methods of biliary drainage included external drainage and external-internal drainage.All the patients were followed up after treatment.The curative effect and operation-correlated complications were observed.Results The first successful rate of PTBD was 97.6％ (124/ 127).The total curative rate,improvement rate and inefficacy rate of interventional treatments were 37.8％ (48/127),44.9％ (57/127) and 17.3％ (22/127) respectively.In biliary leakage group,all the patients were cured by percutaneous interventional treatments with the curative rate being 100％.In anastomotic biliary strictures group,the cure and improvement rates were 64.3％ (18/28) and 35.7％ (10/28) respectively.The efficacy rate was 100％ (28/28).In hilar biliary strictures group,the cure,improvement and inefficacy rates were 40％ (12/30),53.3％ (16/30) and 6.7％ (2/30) respectively.The efficacy rate was 93.3％ (28/30).In multifocal biliary strictures group,the cure,improvement and inefficacy rates were 13.7％ (7/51),54.9％ (28/51) and 31.4％ (16/51) respectively.The efficacy rate was 68.6％ (35/51).In bilomas group,3 cases (3/7) obtained improvement and treatment of 4 cases was inefficative.The efficacy was the best for the patients with bilary leakage,and it was the worst for the patient with bilomas (P＜0.001).The main operation-correlated complication was bile tract infection during drainage.The rates of bile tract infection were 32.4％ (34/105) and 81.8％ (18/22) in patients with external drainage and external-internal drainage,respectively.There was statistically significant difference between these two items (P＜ 0.001).Conclusion PTBD combined with balloon dilation and biliary stent implantation is a safe and effective therapeutic modality for BC after LT,which can improve patients' clinical symptoms,improve patients' quality of life.The patients with bilomas should be treated by retransplantation as soon as possible.The biliary external drainage can decrease the rate of biliary tract infection significantly.
