Is reduction in visceral slide a good sign of underlying postoperative viscero-parietal adhesions in children? Context: Viscera stuck to the anterior abdominal wall from previous surgery risk injury during laparoscopic surgery. A prospective study was conducted to determine if these adhesions are detectable on ultrasound scan by showing a reduction in the normal visceral slide. Patients undergoing laparoscopic procedure after a previous laparotomy underwent preoperative real-time ultrasound scan to observe if viscera slides freely under the abdominal wall. A reduction in slide was considered a positive sign of underlying adhesions. These findings were correlated with the operative findings. Anterior abdominal wall scans were performed on 17 children. Reduced visceral slide was seen in 10. Viscero-parietal adhesions were found in 9 of 10 patients. Visceral slide was reduced in a very localized area in 6 patients, and, in these, a loop of bowel (n = 3), liver and bowel (n = 2), or liver (n = 1) was adherent. In 4, reduced visceral slide was seen over a wide area. Extensive adhesions were found in 3 of 4. One renal transplant patient with peritonitis had a false-positive ultrasound scan. At laparotomy there were no adhesions. The peritonitis is thought to have prevented an adequate examination. Seven patients had normal visceral slide. Of these, 4 had no adhesions, but 3 children had flimsy omental adhesions. The sensitivity and specificity of visceral slide in predicting adhesions were 75% and 80%, respectively.

Reduction in visceral slide is a good sign of underlying postoperative viscero-parietal adhesions. Ultrasonographic mapping of the abdominal wall may be useful in selecting an adhesion-free site for trocar insertion in children with previous operations requiring laparoscopic procedures. Final Decision: yes
