Chronic pancreatitis is accompanied by symptoms simulating those of cancer; the enlargement of the gland, however, is not so great, nor are the indications of pressure upon adjacent organs so prominent. The pain is less severe, the general failure in health more gradual, the progress slower, and constipation less common.
TREATMENT.—The indications are to maintain the strength of the patient, to provide a diet that is nutritious and at the same time easily digested, to allay pain by the employment of narcotics, and to relieve as far as possible the various symptoms as they arise. The plan of administering a calf's pancreas or extractum pancreatis will prove serviceable when the fecal evacuations contain fat. Nutritious and peptonized enemata may be of service in some cases.
Sarcoma and Tubercle of the Pancreas.
Sarcoma of the pancreas occurs with extreme rarity. It is impossible during life to distinguish it from carcinoma.
Tubercle of the gland is infrequently met with. Some pathologists deny its occurrence, and believe that the cases recorded as such are merely instances of caseous degeneration of the neighboring glands. When it does occur, it is always secondary, the primary disease being situated in the lungs or intestines. The alterations in the gland consist in the development of cheesy masses or of miliary granulations in the connective tissue between the acini. The condition gives rise to no definite symptoms, and its diagnosis during life is impossible.
DEGENERATIONS OF THE PANCREAS.
Fatty Disease of the Pancreas.
Two forms of fatty degeneration occur, either separately or combined—namely, fatty infiltration and fatty metamorphosis.
Fatty infiltration consists of a true hypertrophy of the fat-tissue normally existing in the gland, or of an increase and extension into the gland of the peripancreatic adipose tissue. Yellow bands and masses of fat-tissue appear between the acini, and by constantly increasing in size lead gradually to a total atrophy of the cells of the acini. The canal of Wirsung contains a fatty liquid. These changes are found associated with fatty liver, heart, and omentum, in drunkards especially.
