Colonoscopy-Assisted Pneumatic Reduction Of Intussusception

The aim of this study was to evaluate colonoscopyassisted pneumatic reduction(CAPR) of experimental colocolic intussusception(CCI). Twenty eight rabbits were divided into 2 groups each containing 14 rabbits: Group A and B. The animals were not fed orally 1 day before the experimental study and fed parenterally. After median line skin incision, abdominal wall was opened. Colocolic intussusception was performed. 100 ml/kg liquid electrolyte solution was given to all rabbits in postoperative period. Group A was observed for 2 days and Group B for 3 days. In Group A, the “currant jelly” stools were observed. Mean weights were 3.970±2.137 kg, reduction duration 3.97±2.47 minutes, air pressure 44.0±2.6 mmHg, and the success rate of reduction 100%. Perforation was not observed in this group. In Group B, the “currant jelly” stools were observed in 5 of 14 rabbits. Mean weights were 4.111±2.754 kg, reduction duration 4.01±1.71 minutes, air pressure 55.9±13.3 mmHg, and the success rate of reduction 93%. Perforation was observed in 1 rabbit in this group. The air pressure in group B was significantly higher than group A (p
