Enterolith obstruction of the ileum as a complication of jejunal diverticulitis. Report of a case.

A case of intestinal obstruction due to impaction of an enterolith in the distal ileum is reported. The patient had jejunal diverticulosis. One of the diverticula showed evidence of acute inflammation and another showed signs of fibrosis suggesting previous inflammation. Apparently the enterolith had been released from the acutely inflamed diverticulum. One of the diverticula contained a smaller enterolith. The impacted enterolith was removed by enterotomy and the smaller one milked into the intestine. Chemical analysis of the removed stone showed that it consisted of mainly cholic, desoxycholic and fatty acids.

Temporary ischaemia of a large bowel segment induced by degradable starch microspheres in man.

Degradable starch microspheres were used to induce temporary ischaemia measured by electromagnetic flowmetry in colon segments during bowel resection. Severe reversible ischaemia free from unwanted side effects was induced in eight of nine patients. In one of the five patients where the tumour was included in the microsphere-embolised tissue volume no reduction in blood flow was seen. Segmental enteric ischaemia induced by degradable starch microspheres in man seems safe and may be useful for radioprotective purposes in clinical radiation therapy.
