Estenosis benigna de la vía biliar principal / Benign bile duct strictures

El manejo de las estenosis benignas de los conductos biliares es uno de los problemas más difíciles de la cirugía abdominal. El diagnóstico no siempre es evidente a partir de la historia clínica, y la intervención quirúrgica para restablecer el flujo normal de bilis en el tracto gastrointestinal, presenta muchos problemas técnicos y requiere del mayor ingenio por parte del cirujano.Se presenta el caso de un paciente de sexo masculino de 58 años de edad, que presentaba una estenosis del tracto biliar distal de etiología indeterminada, al cual se le realizó una duodeno pancreatectomía cefálica, descartándose la patología maligna.

The management of benign bile duct strictures is one of the most difficult problems in abdominal surgery. Diagnosis is not always clear from the history, and surgical intervention to restore the normal bile flow in the gastrointestinal tract presents many technical issues and it requires the surgeon’s ingenuity. We report the case of a 58 year old male patient who presented with distal biliary tract stenosis of unknown etiology and underwent pancreaticoduodenectomy, which discarded malignancy.

Clinical analysis of 212 patients suffering from benign biliary strictures / 中国综合临床

Objective To analyze the etiology,diagnosis and therapy of benign biliary strictures and im-prove curative and preventive effects. Methods 212 patients suffering from benign biliary strictures in Nankai Hos-pital from January 2004 to December 2006 were retrospectively analyzed. Results Inflammatory strictures (65.12%,140/215) and strictures caused by operations (20.46%,44/215) were the most two causes. Strictures parts were mainly located in the latter segment of common bile duct 52.09% (112/215). In our group,the stent of strictures parts took 31.37% (64/204), bilioendodraignage 18.13% (37/204), and the modification of strictures parts 43.63% (89/204) as well as resection of stricture parts 1.96% (4/204). Conclusions Inflammatory stricture is the main cause in benign biliary strictures and the main locus is the hinder segment of common bile duct. The di-agnesis of benign biliary strictures before operation is important because it can help to decide the approach way and prognosis. The strategies of curing benign biliary strictures could include operations and endoscopy. The stent of stric-tures parts, bilioendodraignage and the modification of strictures parts are the main treaments for benign biliary stric-tures.
