PNEUMATOSIS COLI - AN UNCOMMON BUT TREATABLE CAUSE OF FECAL INCONTINENCE

Pneumatosis intestinalis is defined as the presence of gas within the bowel wall. Small bowel pneumatosis is less commonly reported and more severe than colonic disease in adults. Pneumatosis coli is characteri sed by multiple collections of encysted gas occurring within the sub-m ucosa and subserosa of the colon and rectum. It is an uncommon conditi on which typically presents in late middle age and has been associated with a number of gastrointestinal (e.g. pyloric stenosis, sigmoid vol vulus and ischaemic bowel) and non-gastrointestinal (e.g chronic obstr uctive pulmonary disease, depression and multiple sclerosis) diseases. Some cases, however, are idiopathic or primary. Symptoms can include diarrhoea, constipation, mucus per rectum, bleeding, flatus, abdominal pain and, rarely, faecal incontinence, We report on two patients, one of whom presented with faecal incontinence, the other who had trouble some lower gastrointestinal symptoms including faecal incontinence. Bo th responded well to continuous oxygen therapy.
