[Radiodiagnosis of intestinal endometriosis]. / Rentgenodiagnostika éndometrioza kishechnika.

Twenty-five women aged 24 to 52, suffering from endometriosis of the large and small intestine were examined. The rectum and the rectosigmoid portion were the most frequent sites of involvement. The endoscopic information is absolutely insufficient. The authors distinguish 4 endometriosis forms with different growth forms and degree of the intestinal wall involvement. Each of these forms has a specific x-ray pattern. The condition is to be differentiated from cancer, regional colitis, strictures and pericolitis by x-ray diagnostic methods.

The study was concerned with evaluation of the clinical and roentgenologic data on 57 cases of malignant polyps of the colon. Malignant polyps reaching 10 mm in length were found. Malignancies were identified using endoscopy and biopsy in 58.6% and X-ray examination--45.8%. Among the most effective methods of X-ray examination of the large bowel for cancer should be: high-voltage roentgenography employing incomplete barium enema, primary double contrast examination, direct blow-up and parietography. X-ray signs of malignant transformation of polyps are: persistent retention of barium, wavy and indistinct contours, irregular pattern, rapid growth of neoplasm, retraction of tumor base and disparity between polyp size and its pedicle length.
