The Liver.—The liver should be removed from the body and no attempt made to examine the organ in situ. After raising first one lobe and then the other, the diaphragm should be cut on either side and the suspensory and lateral ligaments divided, then the organ can easily be removed. The weight of the organ is ascertained, as also the measurements of its size recorded. The normal weight is from fifty to sixty ounces. The organ is normally about twelve inches in length by seven inches in depth by three and one-half inches in thickness.
The gall bladder is first examined to determine the character and amount of the bile and the presence or absence of gall stones, inflammatory lesions, and tumors.
At autopsies the surface of the liver, especially along the free border, is generally seen to be of a greenish or dark-brown color. This discoloration is due to the action of the gases developed by decomposition on the coloring matter of the blood, and has no pathological significance. The character of the surface of the liver is now noted, whether smooth or rough. The organ is opened by deep incisions in various directions, and the color, consistency, and blood supply of the liver tissue carefully recorded. The presence of new connective tissue, amyloid degeneration, abscesses, or tumors should not be overlooked. It should be remembered that, of all the poisons, phosphorus alone leaves characteristic appearances in the liver.
The Pancreas.—The pancreas is now easily removed, and its size and weight recorded. Normally it should weigh three ounces and measure eight inches in length by one and one-half inches in breadth by one inch in thickness. The organ should be opened by a longitudinal cut and examined for evidences of acute or chronic inflammation, fat-necrosis, tumors, calculi, and amyloid degeneration.
Genito-Urinary Organs.—It is very important in medico-legal cases that all the urine should be preserved and obtained uncontaminated; therefore before the bladder is opened a catheter should be introduced and the urine drawn off into a clean bottle which has previously been rinsed with distilled water. If more convenient the bladder itself can be punctured at its upper portion, a pipette introduced, and the urine drawn off in this manner.
The genito-urinary organs are removed together. This is done in the following manner. The body of the penis is pushed backward within the skin and cut off just behind the glans penis; the remaining portion of the rectum is raised. This with the prostate gland, bladder, and penis attached is removed by carrying the knife around the pelvis close to the bone and separating the pubic attachments. The organs are then laid on a clean board and the urethra is opened on a grooved director passed into the bladder, and the incision prolonged so that the internal surface of the bladder itself will be completely exposed. Examine the urethra for strictures, inflammatory lesions, and ulcers. Examine the bladder for congestion, hemorrhages, inflammation, and ulcers of its mucous surface, and note the thickness of its walls. Open the rectum and examine for ulcers, strictures, tumors, and the evidence of hemorrhage. The prostate gland is opened by a number of incisions into its substance. Examine for hypertrophies, tumors, and inflammatory lesions. Force the testicles through the inguinal canal, and cut them off. Weigh, open, and examine them for evidence of inflammation, tuberculosis, and tumors.
Female Organs.—Before removing these organs, any abnormalities such as adhesions, malpositions, and tumors should be noted. Dissect the organs away from the pelvic bones by carrying the point of the knife around the pelvis close to the bone. Cut through the vagina at its lower third, and the rectum just above the anus. The organs can now readily be removed. Examine the vulva for ulcers, hypertrophies, and tumors. Open and examine the bladder. Open the vagina along its anterior border and carefully examine its mucous surface for evidences of inflammation.
The Uterus.—Before opening the uterus, its size and shape should be recorded. The average normal weight of the organ is about one and one-quarter ounces; its length three inches, breadth two inches, and thickness one inch. Open the organ along its anterior surface by a blunt-pointed scissors passed through the cervix, and the incision carried as far as the fundus. Note the thickness of its walls and any abnormalities of its mucous membrane. During menstruation, the mucous membrane of the body is thickened, softened, and covered with blood and detritus. Retention cysts are found in the mucous membrane of the cervix and are not generally of pathological significance.
Remove, measure, and weigh the ovaries. Their normal weight is about one drachm each; their size, one and one-half, by three-quarters, by one-half inch. Open the organs by a single incision and examine for the evidences of acute and chronic inflammations, tumors, and cysts. The corpora lutea in various stages can be easily recognized in the substance of the organ. Open the Fallopian tubes and examine their contents and the condition of their membranes (see Disputed Pregnancy and Delivery, Vol. II.).
