This paper evaluated whether multislice CT with rectal enteroclysis (MSCTe) can diagnose bowel endometriosis by using bowel distention, pharmacologic hypotonicity, IV iodinated contrast, and a single volumetric abdominal acquisition. The reported CT findings suggestive of bowel endometriosis were solid nodules with positive enhancement that were contiguous with or penetrating the colonic wall, and the extent of intestinal wall infiltration could be estimated using serosal, muscular, and mucosal layer assessment based on thin-slice isotropic voxels and multiplanar reconstructions. A key limitation explicitly stated was that depth of invasion may be underestimated when nodules reach the submucosa. This paper is centrally about endometriosis — specifically using CT-enteroclysis to detect and assess bowel endometriosis and its depth of intestinal wall infiltration.

Abstract

Although several radiological techniques have been used for the diagnosis of bowel endometriosis, no gold standard is currently established. We used multislice computerized tomography (CT) combined with the distention of the colon by rectal enteroclysis (MSCTe) for the diagnosis of bowel endometriosis. Following bowel preparation, pharmacological hypotonicity, retrograde colonic distention by water enteroclysis, and intravenous injection of iodinated contrast medium, a single volumetric acquisition of the abdomen is performed. MSCTe findings suggestive of bowel endometriosis are the presence of solid nodules with positive enhancement, contiguous or penetrating the colonic wall. When endometriotic lesions are detected, the degree of infiltration of the intestinal wall can be estimated; however, the depth infiltrated by nodules reaching the submucosa may be underestimated. MSCTe is well tolerated by the patients. The strength of MSCT consists in the high spatial resolution; volumetric data acquired by using thin slices provide isotropic voxels and multiplanar reconstructions have a quality comparable with that of the original axial scans. The potential of MSCTe for the diagnosis of bowel endometriosis relies on the fact that the serosal, muscular, and mucosal layers of the bowel wall can be evaluated.
