Anorectal continence and bladder function. Effects of major sacral resection.

The effect of sacral resection up to S-2 has been investigated in two patients with "chordomas," surgical division of the spinal roots was unilateral and bilateral, respectively. Anal manometry, electromyography of the sphincters, and the ascertaining of tactile, thermic, and painful stimuli perception in the perineum and anal canal were executed to determine the effects of denervation on anorectal continence. Vesical function was tested by vesical manometry.

[Histopathology of reflux esophagitis at an early phase. Study and significance of intraepithelial eosinophilia].

The diagnosis of reflux esophagitis in the early stage is not easy because endoscopy rarely shows evident findings and histology of biopsy specimens still appears unclear and doubtful. Usual histopathological findings are reported and most available diagnostic criteria are discussed, on the basis of the literature and personal experience. Intraepithelial eosinophils are a possible marker of early reflux esophagitis: its diagnostic usefulness is outlined.

[Gastroesophageal reflux of mixed type].

Gastroesophageal reflux has been showed both clinically and experimentally to be especially damaging esophageal mucosal layer when the elements which make up reflux are gastric content and bilio-pancreatic juice.
