A decade of adult liver transplantation in a single center in Chile.

INTRODUCTION: Since the early days, liver transplantation (OLT) has conquered several barriers worldwide to become a proven therapy. We assessed the evolution of our adult liver transplant program. METHODS: We studied all adult patients who underwent OLT since the inception from November 1993 through May 2003. Donor data, recipient pretransplantation evaluation, surgical technique, results, and costs were examined over our evolution, stratifying 3 groups over time, based on the number of adult OLT per year. RESULTS: Between November 1993 and May 2003, 70 OLT were performed in 64 patients older than 15 years of age. Preoperative Child score, preoperative creatinine level, donor and recipient age, and proportion of emergencies were similar in the 3 groups. Over time, the predominant surgical technique was the piggyback technique (97% of OLT) with a decrease in the use of bypass from 63% to 5% during the last time period. Over the 10 years of our program's existence, warm ischemia time has been reduced to less than 1 hour, whereas cold ischemia time has remained constant at around 5 hours. Biliary and vascular complications decreased over time to around 10%. The mean length of hospital stay (LOS) decreased to 12 days (excluding emergencies). Since inception, our 1-year patient survival rate average is 91%; however, in just the last 3 years of our program (2000 through 2003), the 1-year patient survival rate is 97%. CONCLUSIONS: In summary, our surgical technique has evolved toward piggyback use without veno-venous bypass with a significant decrease in warm ischemia times. As expected, our results have improved over time and our LOS and costs have decreased. Finally, our current results are similar to the best ones reported in the medical literature today.

Trends in mechanical ventilation and immediate extubation after liver transplantation in a single center in Chile.

INTRODUCTION: Some groups have reported early extubation post-liver transplantation in patients with previously defined criteria, in an attempt to shorten the ICU stay and decrease costs. We review our experience with trends in mechanical ventilation and resource utilization. METHODS: We retrospectively reviewed the length of mechanical ventilation, ICU stay, hospital stay, transfusions, and costs of liver transplants performed since the program's inception in 1993 and 2002 including 82 OLT in 71 patients. We also report our experience with immediate postoperative extubation, which we have done from October to December of 2002. We compare different periods: the early days (1993 to 1997), namely, fewer than 10 OLT per year, with the subsequent years assessed individually. RESULTS: There has been a progressive decrease over time in the length of mechanical ventilation, ICU stay, hospital stay, and costs. Since the program's inception actuarial adult patient 1- and 5-year survival rates were 88.7% and 78%, respectively. The 1-year survival rate increased to 97% during the period of 2000 to 2002 (n = 30). From October to the present, we extubated four of seven adult patients who met criteria with none of them requiring reintubation. CONCLUSIONS: We demonstrate improved results, decreased length of mechanical ventilation, ICU, and hospital stay, and costs. The immediate postoperative extubation may be feasible for patients who meet previously defined criteria.
