[Proctologic examination in pediatrics].
The study included 873 rectal examinations carried out in children where inspection, rectal examination and endoscopy were performed in each case. Most examinations were done in children complaining of gastroenterocolitis. Inspection of gluteal, perianal and sacrococcygeal areas was normal in most cases: however, ammoniacal erythema was frequently found (44.2%). Rectal examination showed hypotonicity of the external sphincter in 146 cases which was linked to prolonged diarrhea and malnutrition. At the endoscopy, the rectal mucosa showed ulcerations, congestion, friability, edema and bleeding; however, it was considered normal in 274 occasions. In 540 patients, the endoscopic diagnosis was colitis of different types. In 54 cases, the endoscopic examination, plus the examination of fecal mucus taken directly from the rectal mucosa led to the diagnosis of amebic colitis. In opposition with adults, neoplastic lesions were uncommon and usually corresponded to leukemic infiltration or tumoral metastases. There were no complications attributable to the process.
