Since then, only two multivisceral transplants were effectively performed, specially due to donor shortage, a common problem faced worldwide. Furthermore, IMT candidates compete with recipients from liver and pancreas transplantation. São Paulo state has an estimated population of 44 million people, 15 million of those living in the capital, São Paulo city. The state encloses two transplantation centers and 9 OPOs. Despite the almost doubling in the annual liver transplant numbers in the last 10 years and improvement in notification, donor care and organ procurement, indicators regarding donor profile and IMT viability (such as donor-recipient size and blood group match, ICU stay, etc) are still lacking. OBJECTIVES We aimed to analyze the epidemiological profile of potential donors based on the organs offered by the regional Organ Procurement Organization from Hospital das Clinicas-USP (OPO/HC-USP), and try to estimate possible matches and program viability. E-poster Number 225 MATERIALS AND METHODS Retrospectively analyzed information from the OPO/HC-FMUSP database regarding organs offered between january-2007 and december-2014, as well as from listed patients in the IMT program. Data regarding donor description profile (sex, age, race, BMI, blood type, cause of death), along with medical care details (ICU stay, use of vasopressors, antibiotics) and lab values were extracted and plotted for analyzes in Microsoft Excel. RESULTS In this time period there were 18.103 brain death notifications in the state of São Paulo, 5.202 (35%) becoming viable donors, resulting in 5.201(99%) effectively used livers. From the OPO/HC-FMUSP the numbers were 2.918, 1.063(36,4%) and 991(93%), respectively. Most potential donors were males, on their forties, from Caucasian origin, and had blood type O. Based on size criteria (<20% of body weight), there would´ve been potentially 11,8 donors/year for the smallest IMT patient and 6,2 donors/year for the heaviest one from OPO/HC-USP. However, only three potential donors would have reached the established minimum combined criteria for IMT donation during these 7 years. CONCLUSIONS Despite public efforts to increase organ donation in Brazil, the characteristics of donors are unsatisfactory for the IMT demand. Meanwhile, one should concentrate efforts on overcoming difficulties in obtaining convenient donors as well as improving intestinal rehabilitation, and possibly consider surgical alternatives, such as bowel-graft shortening techniques.
