Popis: This prospective randomized study examined the acute-phase response and wound healing, comparing laparoscopic (LA) and open posterior (PA) adrenalectomy in a cushingoid porcine model. Repository corticotropin gel was given to 40 pigs for 21 days. Biochemical and tissue parameters of Cushing syndrome were confirmed. The pigs were randomized to undergo LA or PA. In addition to operating time and morbidity, the acute-phase response was compared by measuring the postoperative white blood cell count, fasting glucose, C-reactive protein, and nitrogen balance. Wound healing was assessed by (1) scored (1-4) gross appearance at 48 hours and 1 and 2 weeks; (2) histologic examination; and (3) tensile strength. There was no difference in operating time (mean +/- SD) (36 +/- 9 minutes open vs. 37 +/- 7 minutes laparoscopic), perioperative mortality, degree of leukocytosis, fasting glucose, or C-reactive protein (p0.05). Nitrogen balance, wound scores, and tensile strength at 24 hours and 1 week were more favorable in the LA group than in the PA group (p0.05). In the cushingoid porcine model, laparoscopic adrenalectomy was less catabolic and was associated with fewer wound complications than the open posterior adrenalectomy. These findings provide support for continued pursuit of laparoscopic methods for adrenalectomy in the clinical setting.
