[Dextranomer in the postoperative of anorectal surgery]. / Dextranómero en el postoperatorio de cirugía anorrectal.

Twenty patients were treated with the usual hemorrhoidectomy and fistulectomy techniques; from the nature of the region it was assumed that the postoperative wounds developed infection. Dextranomer was applied locally on 10 patients and the other 10 served as controls. It was observed that the medicament was easy to apply and the patient adapted himself to it quickly enough; none of the group under study presented collateral effects which might contraindicate its use. The healing period was considerably reduced in the problem-group and the patients went back to their usual tasks before expected. Photographic series were taken from all of them during postoperative days until healing. There were not complications in any of the groups under study.

[Angiodysplasia of the colon]. / Angiodisplasia de colon.

The authors present a case review of a congenital abnormality of the inferior mesenteric blood vessels which resulted in ischemia of the descending colon and rectosigmoid area. The resulting colitis is only very rarely secondary to a vascular congenital abnormality. In this case, rectosigmoidoscopy, barioum study of the large bowel and a biopsy of the rectal mucosa pointed towards the ischemic nature of the lesion. This led to the selective angiographic study of the inferior mesenteric vessels with findings of a dilated inferior mesenteric artery and angiodysplasia. Surgical treatment included tying off of the inferior mesenteric artery and resection of the descending and rectosigmoid colon followed by transverse colon-rectum anastomosis. The angiographic and histopathologic studies were of great importance in establishing the true nature of the patient's clinical syndrome. One must keep in mind that the rectosigmoidoscopic findings may be seen in other disease states which do not have a vascular origin. These include Crohn's disease, severe amoebiasis and penumatosis of the intestine.
