Does abdominal surgery performed under general anesthesia increase somatostatin-like immunoreactivity in human serum?
In this human study we showed for the first time that surgical interventions elevate the endogenous SST-LI in human serum. It is assumed that the released SST is derived from the activated sensory nerves. Since antinociceptive and anti-inflammatory effects of neural SST have already been established in laboratory animals, we presume that this endogenous protective mechanism also operates in humans.
Our initial series confirms that aortic valve replacement performed through a right mini-thoracotomy is a safe procedure. When using running sutures, it is possible to obtain cardiopulmonary bypass and cross-clamping times comparable to those for the standard approach. A central cannulation can be performed easily to avoid groin incisions. In conclusion, we believe that this kind of surgery could really be a biologically minimally invasive approach, rather than just an aesthetic choice.
