ABSTRACT

The aim of this paper is to compare the efficiency between standard plastic stents and polyurethane stents used in biliary tract malignant obstruction. The main problem of the plastic prosthesis is their early occlusion. On the other hand there is the hypothesis that due to the less porousness of the polyurethane surface, there might be lesser adherence and consequently a late occlusion. Thirty-eight patients in two groups of 19 were evaluated prospectively and at random in the Jerusalem Hadassah Hospital and the HIGA San Martín La Plata. They had biliary tract obstruction due to inoperable tumors. Biliary endoprosthesis (plastic standard or polyurethane 10 French diameter) were placed, according to the randomization, after a previous staging with clinical examination, laboratory analysis and images. The follow-up with the same parameters was monthly done. Twelve of the 38 patients were female and 26 male; age average 62.73 (range 81-49). The stents were placed in 17 patients with biliary cancer, 14 pancreatic cancer, 2 papila cancer, 2 gallbladder cancer with bile duct invasion and 3 liver metastasis with biliary tract compression. The clinical and laboratory parameters in 36 patients at 30 days improved. On the contrary, 2 (1 plastic standard and 1 polyurethane stent) did not improve. There were 29 deaths due to the basic illness and not related to the endoscopic method. The mean obstruction occurred at 12.76 weeks (range 32-4) in the standard stents and 12.05 (range 24-2) in the polyurethane ones. CONCLUSION: There were no significant differences in the two groups patients.

ABSTRACT

El propósito del presente trabajo es demostrar la utilidad del Drenaje Biliar Percutáneo Transhepático (DBPT) como procedimiento paliativo o prequirúrgico en pacientes con ictericia obstructiva, secundaria a patología maligna o benigna, así como para avaluar y observar el mejoramiento de la calidad de vida en los pacientes con patología maligna. Se estudiaron 28 pacientes, en los que se instaló con éxito en 26 de ellos, diferentes catéteres de drenaje y de calibre en el rango de 8 a 12 F. 14 drenajes fueron de tipo externo y 12 de tipo mixto. La etiología fue neoplasia maligna en 20 pacientes y sólo 8 con patología benigna. En la mayoría de los pacientes se mejoró el estado clínico general y la calidad de vida. Actualmente este procedimiento puede proporcionar información diagnóstica adicional sobre el tipo y nivel de la obstrucción, su extensión y el pronóstico. Provee además de una vía a través de la cual se puede realizar numeros procedimientos secundarios de tipo intervencionista

ABSTRACT

Biliary stent insertion was done in 25 patients. Eighteen were successful, 14 by endoscopic method and 4 by combined endoscopic percutaneous method. Twelve with malignant diseases and 4 with benign diseases had satisfactory drainage. Failed stent insertion occurred in 7 cases. Stent malfunction was found in 30 per cent and occlusion was the most common problem. Complications occurred in 32 per cent and most were mild. The 4 per cent mortality of the procedure is acceptable. Biliary stent should be considered as an alternative or as an adjunctive treatment to surgery.

ABSTRACT

Se presenta la experiencia obtenida con la aplicación de prótesis metálicas expansibles en 35 pacientes con estenosis de las vías biliares. Veinticuatro fueron tratadas por vía percutánea y 11 por vía endoscópica. La edad osciló entre los 16 y 93 años, con un promedio de 67 años. Hubo 26 casos con operaciones previas y 9 sin operar. Estenosis malignas fueron 24 y el resto benignas. De estas últimas hubo 4 iatropatogénicas. El seguimiento varió de 1 a 24 meses. En todos los casos desapareció el cuadro obstructivo. En 2 hubo recidivas a los 2 y 4 meses, pudiéndose corregir el primero. Las estenosis benignas evolucionaron bien, todas excepto una que fue reintervenida a los 5 meses por desplazamiento de la prótesis. No hubo complicaciones de gravedad ni mortalidad atribuible al procedimiento. Los fallecidos lo fueron por la progresión tumoral en un lapso entre los 2 y 16 meses
