BACKGROUND: The pre-transplant period is complex and includes lots of procedures. The severity of liver disease predisposes to a high number of hospitalizations and high costs procedures. Economic evaluation studies are important tools to handle costs on the waiting list for liver transplantation. OBJECTIVE: The objective of the present study was to evaluate the total cost of the patient on the waiting list for liver transplantation and the main resources related to higher costs. METHODS: A cost study in a cohort of 482 patients registered on waiting list for liver transplantation was carried out. In 24 months follow-up, we evaluated all costs of materials, medicines, consultations, procedures, hospital admissions, laboratorial tests and image exams, hemocomponents replacements, and nutrition. The total amount of each resource or component used was aggregated and multiplied by the unitary cost, and thus individual cost for each patient was obtained. RESULTS: The total expenditure of the 482 patients was US$ 6,064,986.51. Outpatient and impatient costs correspond to 32.4% of total cost (US$ 1,965,045.52) and 67.6% (US$ 4,099,940.99) respectively. Main cost drivers in outpatient were: medicines (44.31%), laboratorial tests and image exams (31.68%). Main cost drivers regarding hospitalizations were: medicines (35.20%), bed use in ward and ICU (26.38%) and laboratorial tests (13.72%). Patients with MELD score between 25-30 were the most expensive on the waiting list (US$ 16,686.74 ± 16,105.02) and the less expensive were those with MELD below 17 (US$ 5,703.22 ± 9,318.68). CONCLUSION: Total costs on the waiting list for liver transplantation increased according to the patient’s severity. Individually, hospitalizations, hemocomponents reposition and hepatocellular carcinoma treatment were the main cost drivers to the patient on the waiting list. The longer the waiting time, the higher the total cost on list, causing greater impact on health systems.

The number of pancreatic transplants has decreased in recent years. Pancreatic grafts have been underutilized compared to other solid grafts. One cause of discard is the macroscopic appearance of the pancreas, especially the presence of fatty infiltration. ...

Background: Hybrid liver resection is considered a modality of minimally invasive surgery; however, there are doubts regarding loss of benefits of laparoscopy due to the use of an auxiliary incision. We compared perioperative results of patients undergoing hybrid × open and hybrid × pure laparoscopic resections. Methods: Consecutive patients undergoing liver resection between June 2008 and January 2016 were studied. Study groups were compared after propensity score matching (PSM). Results: Six hundred forty-four resections were included in the comparative analysis: 470 open, 120 pure laparoscopic, and 54 hybrids. After PSM, 54 patients were included in each group. Hybrid × open: hybrid technique had shorter operative time (319.5 ± 108.6 × 376.2 ± 155.8 minutes, P = .033), shorter hospital stay (6.0 ± 2.7 × 8.1 ± 5.6 days, P = .001), and lower morbidity (18.5% × 40.7%, P = .003). Hybrid × pure laparoscopic: hybrid group had lower conversion rate (0% × 13%, P = .013). There was no difference regarding estimated blood loss, transfusion rate, hospital stay, complications, or mortality. Conclusions: Hybrid resection has better perioperative results than the open approach and is similar to pure laparoscopy. The hybrid technique should be considered a minimally invasive approach.
