ABSTRACT
Endoscopic biliary drainage through endoscopic retrograde cholangiopancreatography (ERCP) is a widely accepted therapeutic option in malignant biliary obstructions. However, the procedure is not free of complications. Perforation is one possible complication although it is much less frequent (less than 1%) than pancreatitis (5.4%) or hemorrhage (2%). We present 2 cases of duodenal perforation after placement of a biliary prosthesis through ERCP. Both patients had extensive hilar cholangiocarcinoma. Onset of symptoms of perforation occurred a few hours after placement of the prosthesis and the diagnosis was confirmed by computed tomography and laparotomy. We believe that the mechanism through which perforation occurred was proximal adhesion of the prosthesis to the tumor. This increased the intensity of distal trauma produced by the intraduodenal segment, preventing adaptation of the prosthesis to intestinal peristalsis. A good preventive measure would consist of correctly adjusting the length of the prosthesis in relation to the proximal end of the biliary stenosis.

La perforación esuna de éstas, aunque mucho menos frecuente (menos de 1%)que la pancreatitis (5,4%) o la hemorragia (2%). Presentamos2 casos de perforación duodenal tras la colocación deuna prótesis biliar por CPRE. En ambos casos, se tratabade un colangiocarcinoma hiliar extenso, la clínica relacionadacon la perforación fue de inicio temprano, horas despuésde la colocación de la prótesis, y la tomografía computarizadajunto a la laparotomía confirmaron el diagnóstico de lacomplicación. Creemos que el mecanismo por el cual se produjola perforación fue por fijación proximal de la prótesispor el tumor. Ésta aumentaba la intensidad del trauma distalproducido por el segmento intraduodenal e impedía laadaptación de la prótesis al peristaltismo intestinal. Unabuena medida de prevención sería un adecuado ajuste de lalongitud de la prótesis respecto al extremo proximal de la estenosisbiliar
