[Pseudo-obstruction of the colon].

Pseudoobstruction of the colon is characterized by clinical and radiological findings suggesting a mechanical obstruction of the large intestine without any organic cause. 11 of our patients and 344 cases reported in the literature have been reviewed. 90% of the patients have an associated major system disorder, most of them (40%) are localized in the pelvis. An imbalance in sympathetic-parasympathetic innervation as an aetiological factor is discussed. Diagnosis is generally made on the basis of the plain roentgenogram of the abdomen and a barium enema of the colon. Surgical decompression is indicated when no improvement can be achieved by conservative treatment within 72 hours. Immediate surgical intervention becomes mandatory in case of the cecal diameter being greater than 12 cm or an evident perforation. Cecostomy is of crucial benefit. Extensive necrosis requires a colonic resection.
