Abstract
In the present study, we compared outcomes of biliary drainage by either
percutaneous transhepatic cholangiography (PTC) or endoscopic biliary
drainage (EBD) in patients with malignant hilar biliary obstruction bismuth type
I and II.
This current prospective study was conducted on 60 patients with biliary
obstruction due to malignant hilar liver lesions. Patients were subdivided into 2
equally subgroups: group I (underwent PTC) and group II (underwent ERCP)
for biliary drainage recruited from the endoscopy and intervention radiology
units of the National Liver Institute hospital (NLI), Menoufia University.
All patients were subjected to history taking, physical examination,
laboratory investigations and radiological investigations (abdominal
ultrasonography, dynamic computed tomography (CT) and Magnetic resonance
cholangiopancreatography (MRCP)).
After draining of biliary tree, patients were followed up at 1, 4 & 12
weeks by (Liver tests, renal function tests and ultrasound of the abdomen).
The studied patients in group I were 25 males (83.3 %) and 5 females
(16.7 %) with mean age of 54.60 ± 10.15. About (60 %) of these patients were
smokers and (53.3%) were diabetics. According to Bismuth classification,
twenty-three patients (76.7 %) of these patients were of bismuth class type I.
While, 7 patients (23.3%) were of type II according to Bismuth classification.
The studied patients in group II were 21 males (70%), 9 females (30%)
with mean age with mean age of 63.80 ± 11.94. About (80%) of these patients
were smokers and (56.7%) were diabetics. Seventy three percent of patients
were Bismuth type I and 26.7 % were of Bismuth type II.
