ILEOCECAL TUBERCULOSIS.—Lawrason Brown has recently pointedout that the most characteristic roentgen sign of this disease is a failure ofthe cecum to fill and remain filled in a normal manner with an opaque 848 MEDICAL DIAGNOSIS enema. Whether this sign is due to spasm, to a hypermotility, or to a diffuseinfiltration producing a rigidity of the part of the bowel affected, is unde-termined. The speed with- which this phenomenon manifests itself fromtime to time seems to indicate that it is due to Fig. 444.—Gall bladder disease. Note thickened gallbladder producing deep concaveimpression upon bulbus duodeni. {Dr. Frank S. BisseU.) Tuberculosis elsewhere in the intestine manifests itself in no typicalmanner but is indicated by obstructions or localized narrowing of the bowellumen. CHRONIC ULCERATIVE COLITIS is characterized by an absence ofhaustral markings and at times by a marked narrowing of the affectedcolon. THE STOMACH TUBE 849 GALL-BLADDER.—The degree of precision with which chronic chole-cystitis can be diagnosed roentgenological^ seems to vary directly with theeffort and persistence devoted to the problem. The modern trend seemsto be toward an attempt to demonstrate thickened and hence pathologicalgallbladders rather than gallstones which may be contained therein. Ifone accepts the statistical reports of an increasing number of men of largeexperience, one reaches the conclusion that it is possible to demonstrate
