The consequences of anastomotic leakage following colorectal resection are severe. However, the consequences of stoma reversal are often underestimated. Surgeons should adopt a selective strategy regarding the use of defunctioning ileostomy, and counsel patients further prior to the original surgery. In this way, patients at low risk may be spared the morbidity of stoma reversal.

Perinatal asphyxia can result in neuronal injury with long-term neurological and behavioral consequences. Although hypothermia may provide some modest benefit, the intervention itself can produce adverse consequences. We have investigated whether xenon, an antagonist of the N-methyl-D-aspartate subtype of the glutamate receptor, can enhance the neuroprotection provided by mild hypothermia. Cultured neurons injured by oxygen-glucose deprivation were protected by combinations of interventions of xenon and hypothermia that, when administered alone, were not efficacious. A combination of xenon and hypothermia administered 4 hours after hypoxic-ischemic injury in neonatal rats provided synergistic neuroprotection assessed by morphological criteria, by hemispheric weight, and by functional neurological studies up to 30 days after the injury. The protective mechanism of the combination, in both in vitro and in vivo models, involved an antiapoptotic action. If applied to humans, these data suggest that low (subanesthetic) concentrations of xenon in combination with mild hypothermia may provide a safe and effective therapy for perinatal asphyxia.

In our series, we have demonstrated SILS to be a safe and efficacious method for appendicectomy and cholecystectomy. Further studies are required to investigate any potential advantages of this method over standard laparoscopic techniques.
