Oxamniquine treatment for schistosomal polyposis: a 1-2 year follow-up study.

A follow-up was carried out into the study of schistosomal colonic polyposis reported in the last article. Eighteen patients with schistosomal colonic polyposis were treated with oxamniquine and their progress was evaluated for 2-3 weeks after treatment, at 3 months and at 12-24 months. Sigmoidoscopy to examine mucosa on the polyps and barium enemata to determine the size and number of polyps showed variable success, but treatment with oxamniquine produced no untoward side effects.
