Defecography: I. Description of a new procedure and results in normal patients.

To solve frequently encountered clinical problems in the anorectal area, we have developed a simplified dynamic method of defecography. A radiopaque substance, the consistency of normal stools, is introduced into the rectum and the patient is then seated on a specially designed seat composed of superposed air chambers which, for technical reasons, are filled with water. The movements induced by evacuation of the rectum are recorded using 100-mm ampliphotography. After recording findings in 56 normal patients, we are able to define 5 criteria for "normal": increase in anorectal angulation, obliteration of the impression of the puborectal muscle, wide opening of the anal canal, total evacuation of the rectal contents, and normal resistance of the pelvic floor. The mean value of the anorectal angle (ARA) was 91.96 degrees (+/- 1.52 SEM) at rest and 136.76 degrees (+/- 1.51 SEM) during straining. The increase of ARA during straining is 44.8 degrees.

Defecography: II. Contribution to the diagnosis of defecation disorders.

Our simple method of defecography has proved to be more sensitive than clinical evaluation in the detection and description of defecation disorders. Among the different types of disorders, described on the basis of 144 abnormal defecograms, the most common are rectal intussusception (RI), intraanal rectal intussusception (IRI), external manually (EMRP) or spontaneously (ESRP) reducible prolapses, rectocele, and accentuation of the impression of the puborectalis sling (AIPR). Study of the mean values of the anorectal angle (ARA) (normal mean value = 92 degrees at rest) reveals an increase (p less than 0.05) in the ARA in IRI and ESRP and a decrease (p less than 0.05 at rest, p less than 0.001 at strain) in AIPR. The most striking observation is a highly significant increase (p less than 0.001) in the ARA associated with incontinence.

[Colonic complications of pancreatitis. A report on 39 cases (author's transl)].

Colonic complications of pancreatitis are not infrequent occurrences, as illustrated by the fact that the authors have personally treated 39 such cases. Lesions are found in the colon at sites which correspond perfectly to diffusion of pancreatic necrotic lesions along mesenteric pathways as described by Meyers. They occur mainly in the left colic flexure (17 cases) and transverse colon (10 cases) but may affect the ascending (6 cases) and descending (4 cases) colon by diffusion of the pancreatitis into the anterior extrarenal space. These topographical characteristics, associated with the extrinsic and inflammatory nature of the lesions, produce a very specific and typical radiological syndrome which should assist diagnosis.

[Double-contrast radiologic examination of the colon and rectum].

Double contrast (DC) barium enema is used at many centers as a routine technique for examination of the colon. However, simple contrast enema remains an efficient alternative easy to perform. DC may be performed in a direct manner in a single operation. The contraindications are few (severe colitis, risk of perforation). DC has proved advantageous for detection of polyps and study of inflammatory diseases of the colon. In granulomatous colitis in particular, it contributes to better analysis and differential diagnosis of the lesions, and surveillance of their evolution.

[Plain film findings and contrast enema in colon ischemia (author's transl)].

We describe our observations on abdominal roentgenograms without preparation in two cases of segmental colon infarct and eighteen cases of ischemic colitis. In both infarct cases a colic ileus was noted. In one patient the infarcted loop appeared as gas contrasted. In the ischemic cases there were, in addition to the bowel ileus: a colectasis in two patients, a collapsed segment in thirteen and a gas-filled segment in three. When associated to a significant clinical situation the two latter images have some diagnostic value. In the majority of patients, the contrast enema made possible a diagnosis of ischemic colitis; in three it shaved the sigmoid narrowing responsible for the ischemia.
