The aim of the study was to evaluate the role of colloid osmotic pressure in post-transplant lymphocele pathogenesis. We have analyzed total plasmatic protein and albumin levels, and electrophoresis has been completed in blood samples before transplantation and in days 3 and 14 after transplantation in 50 patients with lymphocele (Lymphocele) and 198 patients without lymphocele (control), respectively. Colloid osmotic pressure (COP) was calculated according to the Hoefs formula. Statistically significant differences were confirmed in albumin levels (42.2 respectively 44.8 g/L) before transplantation (day 0); in total protein (52.5 resp. 55.5 g/L), in albumin (30.1 resp. 32.1 g/L), and COP (15.6 respectively 17.7 kPa) in day 3; and in total protein (52.8 resp. 58.9 g/L), in albumin (30.5 respectively 35.4 g/L), in COP (16.1 respectively 21.2 kPa) in day 14. A potentially critical albumin level was established in 44.1 g/L in the blood analyzed, but its sensitivity was only 62%. The main risk element for the lymphocele formation remains the surgeon's hand. We can proclaim the role of proteins and their COP in the post-transplant lymphocele formation as one of possible pathogenetic cofactors. It is responsible for the impaired mechanisms of the reabsorption the lymph back to the tissues. Better metabolic care could help to reduce incidence of this surgical complication.
