Comparative Study
Cardiovascular responses to prolonged carbon dioxide pneumoperitoneum in neonatal versus adolescent pigs.
Long-lasting minimally invasive procedures are increasingly used for children. However, the hemodynamic effects of a prolonged carbon dioxide (CO(2)) pneumoperitoneum (PP) on small infants are poorly understood and may differ from the effects on adolescents. This study aimed to detect and compare these effects in neonatal and adolescent pigs. ⋯ A prolonged CO(2) PP induces hypotension and cardiac depression in neonatal but not in adolescent pigs. Thus, intensive monitoring during prolonged laparoscopic procedures and particularly afterward may be mandatory for neonates.

The placement of self-expanding metal stents (SEMS) is a safe and effective definitive procedure for the palliation of malignant colorectal obstruction. In this study, the clinical outcomes, including the technical and clinical success rates, and the risk factors associated with the long-term outcomes of palliative SEMS were evaluated. ⋯ Patients with bowel obstruction involving a short segment and those with a distal obstruction had better stent outcomes.
