Abstract
The study was designed to compare patients after laparoscopic and conventional colectomy with regard to early postoperative mood, cognitive function, and neurocognitive variables S100beta and neuron-specific enolase (NSE). Forty-five laparoscopic and 25 open colectomies were enrolled into the prospective study. Outcome measurements were positive and negative postoperative mood (BSKE), neuropsychological tests (Trail-Making Test; word reproduction; Stroop Test), and serum biochemical parameters (S100beta; NSE). Following laparoscopic procedure, patients described significantly better positive mood (P< .05), tended to require less time in the Trail-Making Test and Stroop Test, and had lower postoperative serum concentrations of S100beta compared to conventional colectomy patients (P< .01). The current results revealed several group differences, which, in their entirety, seem to represent a more beneficial outcome after laparoscopic colonic surgery.
