Úvod: Efekt kyanoakrylátových lepidel byl opakovaně hodnocen u resekcí jater, plic a dalších orgánů, ale minimálně u resekcí ledvin. Cílem bylo zhodnocení užití kyanoakrylátového tkáňového lepidla u otevřené a laparoskopické resekce ledviny. Metoda: Byl hodnocen soubor 32 pacientů, kteří podstoupili resekci ledvin s ošetřením resekované plochy kyanoakrylátovým lepidlem. Dvacet tři pacientů prodělalo laparoskopickou resekci a 9 pacientů otevřenou. Byly hodnoceny operační výsledky, komplikace a onkologické výsledky. Výsledky: Medián doby sledování byl 46 měsíců. Průměrná doba byla u otevřené resekce 104 minut a u laparoskopické 157 minut, krevní ztráty byly 250 a 184 ml. Nebyla zaznamenána žádná závažná operační komplikace. Ve sledovaném souboru nebylo zaznamenáno úmrtí ani recidiva nádoru v tříletém pooperačním sledovaném období. Závěr: Hemostáza kyanoakrylátovým lepidlem Glubran II se jevila jako účinná a bezpečná u resekce ledvin. Na druhou stranu zvyšuje náklady na operaci a není nezbytná. Klíčová slova: parciální nefrektomie − laparoskopická resekce ledvin − kyanoakrylátové tkáňové lepidlo, Introduction: The effect of cyanoacrylate glues was repeatedly evaluated in resections of liver, lungs and others organs, but minimally in kidney resection. The aim of our study was to evaluate the use of cyanoacrylate tissue glue in open and laparoscopic partial nephrectomy. Method: We evaluated a cohort of 32 patients who underwent partial nephrectomy with treatment of the resected area using cyanoacrylate glue. Laparoscopic resection was done in 23 patients, while 9 patients underwent an open procedure. Surgical results, complications and oncologic results were assessed. Results: The median follow-up duration was 46 months. The mean time of open partial nephrectomy was 104 minutes and that of laparoscopic resection was 154 minutes; blood losses reached 250 ml and 184 ml, respectively. No serious complications occurred, and all patients survived the 3-year follow-up without any tumor recurrence. Conclusion: Hemostasis using the cyanoacrylate glue Glubran II was effective and safe. On the other hand, it increased the costs of the surgery and was not necessary. Key worlds: partial nephrectomy − laparoscopic resection of kidney − cyanoacrylate tissue glue, and J. Košina, J.

Cardiac surgery is inseparably linked to the activation of innate immunity cells recognizing danger signals of both endogenous and exogenous origin via pattern recognition receptors such as TLR receptors. Therefore, we followed by flow cytometry TLR2 and TLR4 expression on blood monocytes and granulocytes of patients who underwent coronary artery bypass grafting using beating heart surgery (off-pump, n = 34), with use of standard cardiopulmonary bypass (CPB), (on-pump, n = 30), and miniinvasive CPB (mini on-pump, n = 25), respectively, before, during surgery, and up to 7th postoperative day. TLR2 and TLR4 expression both on monocytes and granulocytes was significantly diminished already at the end of CPB being highly significantly decreased at the end of surgery in all patients' groups. TLR2 and TLR4 expression reached preoperative value at the 1st postoperative day being significantly higher at the 3rd postoperative day. Using intracellular staining we found the peak of TLR2 and TLR4 expression inside of monocytes and granulocytes at the first postoperative day in a subgroup of on-pump patients. In conclusion, TLR2 and TLR4 expression is significantly modulated in patients undergoing coronary artery bypass grafting as a part of adaptive homeostatic mechanisms induced by major surgery. The very surgical trauma is responsible for TLR2 and TLR4 modulation. Surprisingly, cardiopulmonary bypass itself was little contributing to the modulation of TLR2 and TLR4 expression. and J.
