A case of endometrioid carcinoma arising from endometriosis of the sigmoid colon is reported. The patient had been treated with unopposed continuous estrogen injection for twenty years after bilateral salpingo-oophorectomy because of severe endometriosis. The pathology, pertinent literature and implications of the present case are discussed.

Recently, promising results with different modifications of an anal continence plug were reported in a pilot study. We have performed a clinical assessment of the plug preferred by the majority of patients in this study in an ambulatory group of patients incontinent to liquid and solid stool. Nine of 14 patients (64 percent; 95 percent confidence interval: 35-87 percent) were continent when they used the plug. In 43 percent (18-71 percent), the plug occasionally slipped out, and 71 percent (42-92 percent) experienced discomfort to a varying degree, which caused 11 patients to withdraw from the study before the end of the planned study period. No correlation was found between the results of anorectal physiology studies and the benefit or inconvenience of using the plug. The overall conclusion is that the majority of patients would use the plug under special circumstances because it eliminates the fear of fecal leakage but that local discomfort, possibly due to the material, would prevent its daily use.
