Transanal anastomosis in the treatment of low rectal strictures due to tribal enemas.

Enema administration is common in Black tribal communities. In the urban environment, toxic and corrosive ingredients may be used which can lead to severe complications. The diagnosis and principles of treatment of complicated proctocolitis of enema origin are discussed. The management of 2 patients who developed long stricutres extending low into the rectum is described. After subtotal rectal and sigmoid resection, continuity was successfully restored using a transanal sleeve anastomosis. Subsequent continence was normal in both patients.

Hamartomatous basal-cell carcinoma.

A 25-year-old woman developed a basal-cell carcinoma in the skin over the right scapula. The histopathology of the lesion revealed elements of typical basal-cell carcinoma as well as adenoid, trichoepitheliomatous, and ductal differentiation. Hamartomatous basal-cell carcimoma is a rare variant of ordinary basal-cell carcinoma as well as adenoid, trichoepitheliomatous, and viduals. It is a less aggressive neoplasm and may remain stationary for years. Its recognition as an entity brings awareness that basal-cell carcinomas sometimes occur in young persons.

Non-occlusive ischaemic colitis in a South African black. A case report.

A rare case of non-occlusive ischaemic colitis in a South African Black is described. The appearance of the bowel at an initial operation, and the histopathological changes demonstrated in the resected specimen after a subsequent operation, provide evidence for this diagnosis. The clinical presentation and radiological features which were also compatible with the diagnosis are presented. While the initiating mechanism remains obscure, it is suggested that ischaemia of the colon wall is likely to have been responsible for the final histopathological picture in this case.

The significance of starch powder contamination in the aetiology of peritoneal adhesions.

The presence or absence of starch granulomas on the peritoneal surface or within peritoneal adhesions is reported in 20 patients subjected to a second laparotomy. Evidence is presented to show that starch granuloma formation is common in the early months following operation and that adhesions associated with starch granulomas cause intestinal obstruction. It is suggested that although starch is usually absorbed within 2 years, associated band adhesions may persist. Glove powder contamination of the peritoneal cavity may thus be a common cause of band adhesion obstruction.
