Experience With Radical Resection in The Management of Proximal Bile Duct Cancer
Multiple surgical and nonsurgical approaches have been advocated for the treatment of proximal bile duct
cancer. However, survival appears longest when a resection can be performed. Fifteen patients treated at a
university center were managed with an aggressive surgical approach. Resection of the tumor was
performed in 13 of 15 patients (87%). Of the patients undergoing resection, major hepatic resection was
performed in 8 (62%), while excision of vessels with reconstruction was performed in 5 (38%). Eleven of
the 13 resected patients (85%) were discharged from the hospital. Clinical symptoms of recurrent disease
occurred between 3 and 36 months after surgery in 7 patients, 6 of whom have died. Three other patients
are alive at 5, 21, and 36 months without clinical evidence of recurrence. There was no correlation between
the completeness of resection and the duration of disease-free survival
Segmental Liver Transplantation From Living Donors Report of the Technique and Preliminary Results in Dogs
A technique of orthotopic liver transplantation using a segmental graft from living donors was
developed in the dog. Male mongrel dogs weighing 25–30 kg were used as donors and 10–15 kg as
recipients. The donor operation consists of harvesting the left lobe of the liver (left medial and left
lateral segments) with the left branches of the portal vein, hepatic artery and bile duct, and the left
hepatic vein. The grafts are perfused in situ through the left portal branch to prevent warm ischemia.
The recipient operation consists of two phases: 1total hepatectomy with preservation of the inferior
vena cava using total vascular exclusion of the liver and veno-venous bypass, 2implantation of the graft
in the orthotopic position with anastomosis of the left hepatic vein to the inferior vena cava and portal,
arterial and biliary reconstruction. Preliminary experiments consisted of four autologous left lobe
transplants and nine non survival allogenic left lobe transplants. Ten survival experiments were
conducted. There were no intraoperative deaths in the donors and none required transfusions. One
donor died of sepsis, but all the other donor dogs survived without complication. Among the 10 grafts
harvested, one was not used because of insufficient bile duct and artery. Two recipients died
intraoperatively of air embolus and cardiac arrest at the time of reperfusion. Three dogs survived, two
for 24 hours and one for 48 hours. They were awake and alert a few hours after surgery, but eventually
died of pulmonary edema in 2 cases and of an unknown reason in the other. Four dogs died 2–12 hours
postoperatively as a result of hemorrhage for the graft's transected surface. An outflow block after
reperfusion was deemed to be the cause of hemorrhage in these cases. On histologic examination of the
grafts, there were no signs of ischemic necrosis or preservation damage
Neurologic complications in adult living donor liver transplant patients: an underestimated factor?
Liver transplantation is the only curative treatment in patients with end-stage liver disease. Neurological complications (NC) are increasingly reported to occur in patients after cadaveric liver transplantation. This retrospective cohort study aims to evaluate the incidence and causes of NC in living donor liver transplant (LDLT) patients in our transplant center. Between August 1998 and December 2005, 121 adult LDLT patients were recruited into our study. 17% of patients experienced NC, and it occurred significantly more frequently in patients with alcoholic cirrhosis (42%) and autoimmune hepatitis (43%) as compared with patients with hepatitis B or C (9/10%, P = 0.013). The most common NC was encephalopathy (47.6%) followed by seizures (9.5%). The choice of immunosuppression by calcineurin inhibitor (Tacrolimus or Cyclosporin A) showed no significant difference in the incidence of NC (19 vs. 17%). The occurrence of NC did not influence the clinical outcome, since mortality rate, median ICU stay and length of hospital stay were similar between the two groups. Most patients who survived showed a nearly complete recovery of their NC. NCs occur in approximately 1 in 6 patients after LDLT and seem to be predominantly transient in nature, without major impact on clinical outcome
Resecci\uf3n de hepatoma o trasplante
Los tumores m\ue1s frecuentes del h\uedgado se originan en los hepatocitos, el epitelio de los conductos biliares y las c\ue9lulas endoteliales. El carcinoma hepatocelular constituye 80 a 90% de los c\ue1nceres primarios del h\uedgado. El colangiocarcinoma, neoplasia que se origina en el \ue1rbol biliar, es la segunda enfermedad maligna primaria del h\uedgado m\ue1s frecuente. En este art\uedculo se habla de los aspectos epidemiol\uf3gicos y el cuadro cl\uednico as\ued como de la confirmaci\uf3n diagn\uf3stica y la clasificaci\uf3n de ambos trastornos. El art\uedculo termina con una descripci\uf3n del tratamiento mediante resecci\uf3n hep\ue1tica y trasplante para ambos tipos de trastornos
