Perihepatitis.

DEFINITION.—By the term perihepatitis is meant an acute inflammation of the serous envelope of the liver. It may be acute or chronic, very rarely the latter, and it is usually a secondary affection, although primary cases are not uncommon.

PATHOGENY.—Inflammation of the hepatic portion of the peritoneum may arise by an extension of the morbid process from neighboring parts, as in perforation of the stomach or duodenum, pleuritis of that part of the membrane reflected from the diaphragm, etc. More frequently it arises by contiguity from some disease of the liver itself, as chronic interstitial hepatitis, abscess, echinococci cysts, cancer, etc. The author has frequently (comparatively) seen perihepatitis follow the passage of gall-stones. It is usual to find considerable organized exudation at the hilus of the liver in the case of those who have had several attacks of hepatic colic, and attachments to various neighboring parts also. In those instances of secondary hepatitis there may be more or less extensive connective-tissue formation and compression of the hepatic substance (Budd).⁴⁷

Direct perihepatitis arises from traumatic causes—from contusions of the right hypochondrium by spent balls, blows and falls, etc. Tight-lacing and wearing a strap to support the trousers are supposed to excite a slow, chronic hepatitis, but the latter is more certain to bring about such a result than the former.

SYMPTOMS.—Acute perihepatitis, if of sufficient extent, causes more or less fever; pain is felt in the right hypochondrium, and is increased by pressure and by deep inspirations, and in some rare instances a friction murmur is audible synchronous with the respiratory movements. These symptoms succeed to attacks of hepatic colic, perforation of the stomach or intestine, and contusions of the abdominal wall. The chronic form is not febrile; there is a feeling of soreness instead of acute pain; pressure, the movements of the body, respiration, etc. increase the distress, and on turning on the left side a painful dragging is experienced. A slight degree of icterus may be present in both acute and chronic cases.

COURSE, DURATION, AND TERMINATION.—The course of the acute cases is toward recovery. In two or three days the inflammation reaches the maximum, adhesions form, and then the morbid process declines. The whole course of an acute perihepatitis caused by external injury or by the passage of gall-stones is terminated in a week or ten days. The mischief done may not be limited to the adhesions formed. The large quantity of newly-organized connective tissue may, in its subsequent contraction, compress the common, cystic, or hepatic duct, or the portal, or both ducts and vein. The course of the chronic cases is determined by the causative lesion. The contraction of the new-formed connective tissue may compress the organ and lead to sclerotic changes which cannot be distinguished from cirrhosis. In some instances contusions set up suppurative inflammation, and an abscess forms between the parietal and glandular layer of the peritoneum. Such a case will then present the phenomena of hepatic abscess.

DIAGNOSIS.—The determination of the character of the case will be largely influenced by the history. If the attack has followed a blow on the side or a paroxysm of hepatic colic or the symptoms of perforation, there will be no difficulty in determining its seat and character. In the absence of the history the differentiation must be made between perihepatitis and pleuritis. The distinction consists in the fact that in the former the pain and soreness are below the line of respiratory sounds, although synchronous with them. In chronic perihepatitis the symptoms come on in the course of the hepatic disorder, or are consequent on a local injury, as the pressure of stays or a band.

TREATMENT.—If the symptoms are acute and the subject robust, the local abstraction of blood by leeches affords relief and diminishes the violence of the disease. A bandage should be tightly applied around the body at the level of the hypochondrium to restrain the movements of the affected organ. A turpentine stupe may be confined in this way, or a compress of water may be utilized to serve the same purpose. If the pain is acute and the peritonitis due to perforation or to the passage of calculi, the hypodermatic injection of morphia is the most important resource.
