RESUMO
Objective To investigate the value of percutaneous balloon dilation and percutaneous transhepatic cholangial drainage (PTCD) catheter maintenance in the treatment of benign biliary strictures.Methods The clinical data of 21 patients with benign biliary strictures at Peking Union Medical College Hospital from June 2005 to June 2011 were retrospectively studied,in which 12 patients in severe stricture (stenosis ＞ 70％ ) were treated with percutaneous balloon dilation and PTCD catheter placed across the stricture,while another 9 patients in median stricture( stenosis ＜ 70％ ) were only treated with PTCD catheter maintenance.Results Of the 12 patients underwent balloon dilation and 6-12 months ( median:9 months)of PTCD catheter placement,11 patients had the catheter successfully removed.In the follow-up of 6-24months ( median:10 months),patency of bile duct was preserved in 9 of 11 patients,and recurrent stenosis was seen in 2 patients.A severe complication with biliary artery branch rupture and massive hemobilia was seen in 1 patient during balloon dilation.Of the 9 patients only treated with 1-12 months (median:6months) of PTCD catheter placement,7 patients had the catheter successfully removed.In the follow-up of 5-18 months (median:8 months),patency of bile duct was preserved in 5 of 7 patients,and recurrent stenosis was seen in 2 patients.No severe complication occurred.Conclusions When endoscopy therapy is failed or the patient can't undergo endoscopy therapy,the percutaneous balloon dilation and PTCD catheter maintenance method is an effective alternative therapeutic approach in the treatment of benign biliary strictures.The moderate benign biliary stricture may be effectively treated only by the PTCD catheter maintenance method.
RESUMO
Renal lymphangiomatosis is a rare developmental malformation of the perirenal lymphatic system, and this can result in the development of cystic masses in the peri-pelvic or peri-renal areas. This is difficult to differentiate from other cystic renal disease on imaging studies. We present here a case of metachronous bilateral renal lymphangiomatosis that was falsely diagnosed as a simple renal cyst. A 47 year-old man was referred for a large amount of drainage after right renal cyst marsupialization. The abdominal computed tomography(CT) findings and fluid analysis were compatible with a lymphangiomatosis. After 6 month, he presented with flank pain on his left side and CT showed intracystic hemorrhage on the left renal lymphangiomatosis. Percutaneus drainage and conservative management were done.
