Appendiceal Colic in Childhood The Role of Inspissated Casts of Stool within the Appendix

Abstract

Seventy pediatric patients with histories of recurrent crampy abdominal pain, right lower quadrant tenderness, and proven filling defects or distention of the appendix on radiographs, have been subjected to appendectomy. Inspissated fecal material was found within the appendix in 72.8% of such children. Fecal material was found in only 12.9% of 155 normal appendices and in 33.8% of 530 acutely inflamed appendices. It is postulated that inspissated fecal material acts as a foreign body of the appendix, leading to intermittent obstruction and distention of the appendix--appendiceal colic. An 86% correlation between the appendiceal filling defects seen on radiographs and the inspissated fecal material found within the appendix at operation has been noted. Ninety-six per cent of these 70 children had been relieved of their recurrent abdominal pain by appendectomy. Appendiceal colic characterized by crampy abdominal pain, right lower quadrant tenderness, and appendiceal filling defects appears to be a veritable and verifiable diagnosis.
