=Diagnosis=, as a rule, is not a difficult matter. The various neurasthenic symptoms in a lean patient with constipation, indigestion, and stomach and intestinal distress would lead one to suspect intestinal displacement. The outline or contour of the abdomen will often reveal the character of the trouble. The atonic, thin and relaxed walls of the abdomen may readily give view of the displaced organs. Then careful examination by palpation and percussion will help very materially in the diagnosis. Radiographic examination is a decidedly helpful diagnostic method. The =hepatic flexure= is frequently prolapsed. The bowel (colon) ascends from below upward to beneath the costal arch and then angles sharply into the transverse colon, which extends directly across the abdomen to the left side. The ligaments that support this flexure are apt to become weakened or stretched and allow a descent of this section of the bowel, which is followed by constipation, indigestion, etc. The ligament especially involved is the colo-hepatic ligament. The =duodenum= may require attention. This can be raised by getting beneath it where the organ descends alongside of the ascending colon. The effect of treatment is to release tension of the duodeno-hepatic ligament which is closely associated with the portal vein, hepatic artery and bile-duct. The =ileo-cecal region= is an area that readily becomes congested and catarrhally inflamed, especially from constipation or impaction at this point. The section often becomes atonic and prolapsed with resultant clogging of fecal matter. Owing to the close proximity of the vermiform appendix, appendicitis frequently results from the above condition. The osteopath can do much in these cases of appendicitis. Lesions are invariably found in the lumbar vertebræ or the floating ribs are depressed. The =sigmoid flexure= is also frequently prolapsed. The fecal mass often becomes impacted here, owing to a settling or prolapse of this part. In some cases the prolapse is so marked that it extends to the rectum below and drags on the splenic flexure above. Lumbar and innominate lesions are the usual causes, although, it seems in a number of instances, that relaxed walls of the abdomen cause a “contraction of the diaphragm resulting in kidney displacement and followed by intestinal prolapse.” The vertebral lesions, probably, first weaken the muscular coat of the bowel, then, second, the bowel supports (other than its own inherent tonicity) and the abdominal walls.
