Use of locally innovated radiopaque markers (MAKKO pills) for colonic transit study

ABSTRACT

Locally made radiopaque markers for colonic transit study are presented, specifically on how they were made, and how they compared radiographically with markers available abroad. These markers were produced using locally available materials like barium powder, a feeding tube, cyanoacrylate, and emptied drug capsules. They were then ingested and monitored by X-ray. They were found to be radiographically comparable with imported ones. No adverse events were noted when used in 5 patients 2 patients with constipation secondary to chronic laxative abuse, 2 patients with reducible complete rectal prolapse, and 1 patient with constipation secondary to short segment Hirschsprungs' Disease.
