ABSTRACT
Introducción: Las complicaciones del tracto biliar posteriores al trasplante ortotópico de hígado (TOH) son uno de los problemas más importantes, ya que pueden ocasionar disfunción del injerto y muerte. Objetivo: Evaluar la incidencia de las complicaciones biliares posteriores al TOH en la serie de nuestra institución. Metodología: De forma retrospectiva se evaluaron las historias clínicas de 254 pacientes a quienes se les realizó TOH con donante cadavérico y se identificaron aquellos pacientes que presentaron complicaciones biliares. Resultados: Se documentaron 25 pacientes con complicaciones biliares, para una frecuencia de 9,84%; 21 casos (84%) de estenosis biliar, de estos, 16 (64%) estenosis anastomóticas y 5 (20%) estenosis no anastomóticas. Hubo 7 casos (28%) de fugas biliares. Otras complicaciones fueron menos frecuentes. La sobrevida es de 88% con una media de seguimiento de 37,8 meses. Conclusión: Las complicaciones biliares pos-TOH continúan siendo frecuentes, sin embargo, el desarrollo en las técnicas de intervención endoscópica y percutánea han mejorado el pronóstico general de estos pacientes.
Introduction: Biliary duct complications following an orthotopic liver transplant (OLT) are some of the most important problems since they can cause graft dysfunction and death. Objective: Evaluate the incidence level of biliary complications following OLTs in our institution. Methodology: The clinical charts of 254 patients who had had OLTs with deceased liver donors were retrospectively evaluated to identify those who developed biliary complications. Results: 25 patients with biliary complications, or a frequency of 9.84%, were documented. 21 cases (84%) had biliary strictures. Of these 16 (64%) had anastomotic strictures and 5 (20%) had non-anastomotic strictures. There were 7 cases (28%) of biliary leakage. Other complications were less frequent. The survival rate is 88% with mean follow up time of 37.8 months. Conclusion: Post OLT biliary complications are still frequent; however, the development of endoscopic and percutaneous interventions has improved the general prognosis of these patients.

Two cell strains from human pancreatic cancer taken surgically were transplanted to the pancreas of pureline BALB/C-nu/nu nude mice and 9 generations of PTNMP-1 and 6 generations of PTNMP-2 were obtained. Biological properties were studied. It yielded a transplant success rate of 95% - 100% and large amount of CEA. Analysis of the karyotype confermed that they retained the karyotype of human cancer cells. Some lymphatic and blood stream metastasis and invasion could be found in the nude mice orthotopically transplanted with tumour, showing that the transplanted tumour had characteristics identical with the donor tumour.
