Comparison of thrombocytopenia in hepatectomy for neoplasia <span class="elsevierStyleItalic">vs.</span> living liver donation has not been previously described. We performed a retrospective review of all patients who underwent right lobe hepatectomy from 2005 - 2015. Throm-bocytopenia was defined as a platelet value of less than 150 x 10<span class="elsevierStyleSup">9</span>/L. Spleen sizes were measured before and after surgery in the coronal and axial planes, with the largest diameter used. Ultrasound evaluation was used if cross sectional imaging was unavailable. We excluded patients who received chemotherapy (n = 15) which may influence platelet values in the post-hepatectomy period. There were no patients with cirrhosis in either group. We compared platelet values in the postoperative period of patients who underwent right hepatectomy for living donation (n = 93) to those who underwent hepatectomy for neoplasia (n = 21). We used unpaired and paired <span class="elsevierStyleItalic">t</span>-tests to compare both groups. Mean age of patients in the neo-plasia group was 53 ± 16, and 57% were females. Mean age of living donors was 37 ± 11, and 58% were females. Six patients in the neoplasia group had thrombocytope-nia, three at 12 months, two at 3 months, and 1 patient that was lost to follow up after the first month. In the living donor group, seven patients had thrombocytopenia at 12 months, seven patients at 3 months and two patients at 1 month. There was no significant difference in platelet values between the two groups at one month (291.2 ± 100 <span class="elsevierStyleItalic">vs.</span> 285.73 ± 159, p = NS), three months (223.8 ± 61 <span class="elsevierStyleItalic">vs.</span> 185.27 ± 80, p = NS) and at 12 months (212 ± 44 <span class="elsevierStyleItalic">vs.</span> 191 ± 60, p = NS). There was a significant difference in pre- and post-hepatectomy spleen sizes in both groups of patients with available data (n = 36), 11.2 ± 1.43 cm <span class="elsevierStyleItalic">vs.</span> 12 ± 2.12 cm, p = 0.014 with a median follow up period of 32 days in the living donor group and 335 days in the neoplasia group.</p><p id="p0040" class="elsevierStylePara elsevierViewall">There are several limitations of our study.
