title: Endometriosis of the sigmoid colon: a diagnostic problem.
abstract: Colonic endometriosis is often difficult to diagnose pre-operatively and most cases are diagnosed postoperatively from histology. The main problems with pre-operative diagnosis are due to the radiographic similarities between endometriosis and malignant lesions and the difficulties in obtaining satisfactory biopsy material.
