=Abdomen.=—The position for examination of the abdominal viscera is usually with the patient supine, head slightly elevated, knees drawn up partially and supported to relieve any muscular strain, and with the hands at the sides. In this position complete relaxation is obtained. Observe any enlargements from gas, fluid, or tumor, muscular changes, color, etc. The patient may, also, be placed upon the side, and in the knee-chest position for further verification of the diagnosis. Where the abdominal wall is much relaxed, or there is a pendulous abdomen with enteroptosis, there will be found a change of relations of the viscera by these different positions, allowing them to be palpated in another position. When there is marked tenderness it is often possible to go deeper with less discomfort with the patient in the knee-chest position. The Trendelenburg position may also be utilized. Where ascites is suspected palpation should be made with the patient in various positions in order to note changes of location of the fluid. Frequently much can be learned by inspection with the patient standing. Clues to visceral disturbance can often be had by tracing the nerve connection from the spinal lesions to the suspected part. In examining the =liver= care must be taken that any gouging or severe bruising of the organ does not take place. The liver can be outlined by percussion and also by palpation of its lower and inner borders Congestions, atrophy, enlargement or hardening should be noted, also any change in position. A rather complete examination can be given the =biliary tract= from the =gall-bladder= to the =duodenal orifice= of the =biliary duct=. By a careful inhibitory pressure over the duct the outline of the tract can be discerned providing the patient is not too stout. When the tract is swollen considerable tenderness will be present. The patient will complain of a stabbing or piercing pain upon pressure and manipulation if the duct is inflamed. Usually the tenderness is greatest nearer the =duodenal orifice=. The duodenal orifice is about one and one-half inches diagonally downward to the right from the umbilicus. In cases of impacted =gall-stones= the osteopath as a rule has very little trouble in locating the stone. The =spleen= may be percussed and when in a markedly enlarged condition its lower border can be palpated. Great care must be used in the latter condition as there is danger of rupture. In examining the =stomach= the usual methods of inspection, palpation, percussion, analysis of the contents, etc., are employed.
