Under the head of mild forms can be included all cases of intestinal

catarrh which by their short duration and benignant character point to

a mild degree of inflammation. They correspond to the following

anatomical states: hyperæmia of the mucous membrane of parts of the

small or large intestine, or of parts of both simultaneously; slight or

moderate swelling of the membrane from serous saturation; transudation

of serum into the canal; increase of lymphoid cells in the mucous and

submucous tissues; and increased manufacture of epithelial cells, but

without any marked tumefaction or ulceration of the closed follicles.

The termination is by resolution, which is reached in a few days

usually, and the membrane is rapidly and entirely restored to the

normal state. Between the normal condition of the mucous membrane, with

its recurring periods of physiological hyperæmia, and the hyperæmia

with exaggerated secretion and peristalsis which leads to diarrhoea,

there is no well-defined border-line. Diarrhoea may be regarded as the

most certain sign of the catarrhal process. Whenever the frequency and

fluidity of the stools are such as to be regarded as pathological, some

stage or other of catarrhal inflammation may be assumed to exist.

In a large number of mild forms the onset is sudden. After a meal of

indigestible food or an unusual excess pain will be felt in the

abdomen, recurring in paroxysms, which start in the neighborhood of the

umbilicus and radiate throughout the abdomen. The pain is accompanied

by borborygmi, and is succeeded sooner or later by a desire to go to

stool. The first one or two movements, which follow each other in quick

succession, are more or less consistent or moulded, but in a short time

diarrhoea is established by frequent discharges of watery fluid,

containing perhaps some undigested fragments of food, which may have

been the exciting cause of the illness by mechanical irritation. Each

stool is preceded by colics, griping pains in the abdomen, which are

relieved by the evacuation. An attack beginning in this way and from

such causes may cease in a few hours, and be unattended by any general

symptoms if proper precautions are taken. A slight dryness and coating

of the tongue, with loss of appetite and occasional griping pains or a

tendency to looseness of the stools, may continue for a day or two.

Indiscretions in diet or other imprudences, as fatigue, may prolong the

mildest attack during one or more weeks, but the character of the

illness is here due not to the nature of the disease, but to the

addition of fresh causes which delay the natural progress toward

recovery.

Severer forms either begin suddenly, as in the milder forms just

described, or are preceded for a time by symptoms of gastric or

intestinal indigestion. The patient may have complained of distress

after eating, flatulence, colicky pains, distension of the abdomen and

tenderness on pressure, loss of appetite, with a general feeling of

ill-health--symptoms which point to the existence of a condition of the

mucous membrane of the gastro-intestinal canal favorable to the action

of an exciting cause.

A feeling of chilliness ushers in the attack. This is accompanied by

fever, which at first, and sometimes throughout, is of a marked

remittent type. {679} The griping pains, colics, which at first are

infrequent and dull, now recur at short intervals and become sharper.

They are sometimes attended with vomiting of food or of a greenish

fluid. The intensity of suffering may be so great as to cause pallor of

the countenance, a feeling of faintness, and coldness of the surface

with sweating. The paroxysm usually precedes a movement. The more

severe pains extend to the lower extremities and the scrotum.

Movement of gas in the intestines produces rumbling, gurgling, or

splashing sounds, called borborygmi. They are paroxysmal, lasting a few

moments, or are coincident with pain, and frequently are the immediate

precursors of an evacuation. The cause for their production is the

quick propulsion of the fluids by strong peristaltic action from one

part of the bowel to the other or the rapid movement of gas within the

bowel. Relief is obtained both from the pain and from the sense of

distension by expulsion of flatus.

Tympanites is closely connected with the symptoms just described. An

excess of gases within the bowel is not primarily a result of the

inflammation of the mucous membrane, but is an early phenomenon due to

the decomposition of indigestible food in its transit through the

intestine. Later, the gases are developed very readily by the

decomposition of even the most digestible articles of food, the mucus,

which is the product of the catarrh, acting as a ferment.

The distension of the intestinal canal produces an intumescence of the

abdomen which is commonly uniform, but may be greater in some portions

of the tract than in others. Thus the transverse and descending colon

are more projecting and more distinctly outlined than other portions of

the canal.

Sensibility of the abdomen to pressure exists along the line of the

colon or over a considerable area. But no defined limitation of the

affected part can usually be made by the location of pain to the touch.

If there is any local tenderness, it is over the descending colon. In

one form of enteritis--typhlitis--the localization of the inflammation

in the cæcum produces subjective pain and pain on pressure in a

restricted region--a peculiarity which results no doubt from the early

intensity of the inflammation and the implication of the connective

tissue behind the bowel. But this is not true of inflammation of any

other part of the intestinal canal.

A sensation of soreness on movement, as in turning in bed, standing, or

walking, is not uncommon, even when the attack is of no great gravity.

The patient on standing bends forward to relieve tension, and he may

feel nervous when the bed is shaken.

Diarrhoea is the most important symptom, as it is directly related to

catarrh. The number of evacuations varies from one or two to twenty or

more in the day. In cases of medium intensity there are from six to ten

in twenty-four hours, the interval between the movements being two to

three hours during the day and somewhat longer at night. The matters

passed in quantity range from two ounces to a pint; the average is

about four fluidounces. This, however, is subject to great variations,

depending upon the intensity of the disease; the more choleriform the

attack the greater the amount of fluid passed. The weight of the

evacuations varies from five ounces to forty pounds in twenty-four

hours; this increase does not depend upon the greater quantity of water

only, but the solid constituents are in greater amount.

{680} The normal brown color, which is due to hydrobilirubin, changes

as the movements become thinner to yellowish-brown or pale yellow from

dilution of the fecal matter with water. An excess of serum or mucus

renders them colorless. A greenish-brown, greenish-yellow, or green hue

is due to the presence of bile. The rapid descent of the contents of

the bowel delays or prevents the reabsorption of bile,[22] or the fluid

is expelled before the usual transformations in color take place.[23]

The bile-pigment is also absent in duodenal catarrh from closure of the

opening of the ductus choledochus.

[Footnote 22: L. Brunton, "On the Action of Purgative Medicines," _The

Practitioner_, London, June, 1874, p. 403.]

[Footnote 23: The reaction of bile-pigment with nitric acid, which does

not take place in the contents of the colon or in normal feces, is seen

in the green stools of acute intestinal catarrh, especially in

children.]

The coloration of the stools further depends upon the character of the

food and drink and upon the drugs given. From an exclusive milk diet

the discharges are pale or contain undigested whitish lumps of casein.

The preparations of bismuth and iron give a black color and the

sulphate of copper a dark-green hue. A green or greenish-brown tint is

observed after the use of calomel, and while the experiments of the

Edinburgh committee demonstrated that no increase of bile follows its

administration in dogs, yet the opinion is still general that the green

stools contain an excess of bile.

Blood appears in three forms in the stools: as a coffee-ground or black

powder from hemorrhage in the stomach or upper bowel; as a reddish

fluid with small coagula in flakes, which come from intense congestion

or ulceration of the intestine; or an abundant hemorrhage may result

from deep ulceration in the duodenum or elsewhere.

The characteristic odor of the feces is altered in several ways. As the

movements become less solid they acquire a nauseous or sour smell, due

essentially to the volatile products formed in connection with the

decomposition of fatty matters.[24] When very thin and containing

little or no feculent matter the discharges lose odor, as in cholera,

or they become excessively offensive--cadaveric--in intense and fatal

inflammation and in ulceration of the bowels. After exposure to the air

the stools of diarrhoea undergo decomposition and develop offensive

smells more rapidly than in health. The absence of bile, whether there

is diarrhoea or not, gives rise to a peculiar and unpleasant odor,

showing that this secretion is to some extent an antiseptic. The escape

of fetid gas from the anus is rarely an accompaniment of a decomposed

state of the rectal contents. In children the stools are more variable

in quantity, color, and odor than in adults, and are more readily

affected by the ingesta.

[Footnote 24: Guttmann, _Physical Diagnosis_, Sydenham Soc. ed., p.

404. The odor of normal feces is due to a substance isolated by

Briequer, called scatol, which is a final product of the putrefaction

of albumen (Ewald, _Lectures on Digestion_, New York, 1881, p. 106).]

In the diarrhoea of old persons the discharges are thin, yellow,

offensive, and often frothy.

The disorder of the digestive apparatus is attended with other

symptoms. The tongue is normal in some cases; in others red at the

point and edges with a central whitish coat, or the surface is red,

polished, and dry. Marked change in the appearance of the tongue is due

to a complicating gastric catarrh. There is thirst, with loss of

appetite, and a tendency to {681} nausea and vomiting in children and

feeble persons. The breath has a peculiarly offensive odor (spoken of

as fecal) in some instances.

Fever is not always present. In cases of moderate severity it occurs in

the beginning of the illness, but declines rapidly under treatment by

rest and diet. The course of fever does not conform to any type even in

severe cases, although it so nearly resembles that of typhoid fever in

its first week as to lead to mistakes in diagnosis. The height of the

fever and its duration are measures of the extent of the lesions and

their gravity. Sudden outbursts of fever point to some complication. In

catarrh of the bowel due to cold the fever is higher than when

indigestion is the cause. In very feeble persons, in children, and in

any case from neglect and improper feeding the body-heat may be very

high.

The urine is diminished and high-colored. Very little disturbance of

the nervous system is seen except in young and old patients; some

headache and restlessness are all that may be observed. Moderate

delirium at night accompanies very acute attacks. In children

convulsions are not unusual in the onset and at the end of the attack.

In the aged exhaustion from the illness soon lapses into stupor or

coma.

Paraplegia and contraction of the muscles of the extremities are

referred by some observers to gastro-intestinal inflammation.[25]

[Footnote 25: Potain, _Le Praticien_, Paris, 1879-80, p. 88.]

In uncomplicated mild cases of intestinal catarrh there is a movement

toward recovery after a few days' illness. The stools become less

frequent, smaller, and more consistent. In a week to ten days the

tongue cleans, the thirst ceases, the appetite returns, the tympanites

and pain diminish. The fever declines, and ceases before the diarrhoea

is completely arrested. There are always more or less emaciation and

loss of strength from the fever and arrest of nutrition. The liability

to relapse is great, and the patient by indiscretions reproduces the

same symptoms, thus prolonging the attack for several weeks. Acute

intestinal catarrh may pass into the chronic form by a disappearance of

fever and amelioration of all the abdominal symptoms. The patient

begins to take solid food, gains strength and flesh, but complete

recovery does not come. The diarrhoea recurs at variable intervals as

the result of indulgences in a mixed diet, over-exercise, or exposure

to cold, and in time we have some degree of chronic catarrh permanently

established.

Very mild cases may be prolonged by the neglect of the patient to

consider his painless diarrhoea of sufficient moment to need attention.

In inflammation of the more intense kind the picture is somewhat

different. The prodromes are longer and the general symptoms more

severe. Restlessness, a sense of prostration, delirium, and high fever

mark the early stages and continue for a longer time. The patient loses

flesh and strength quickly. The features express anxiety and illness,

the skin is hot and dry, and the thirst great. Vomiting is repeated.

Borborygmi, the tension of the abdomen, pain, and sensibility to

pressure are all intensified. The stools are at first yellow and thin,

but change much from day to day. They may be green or very thin and

dark or grayish, and are sometimes very offensive in odor. Blood and

mucus may be seen in them, being slimy or grumous and bloody. When the

patient is very weak the discharges are involuntary; the tongue is

coated white, with bright red tip and edges, and is often dry.

{682} The severer forms last from three to six weeks. After a tedious

period of alternate improvement and relapse the illness becomes chronic

or the patient dies from asthenia, perforation and peritonitis, or some

other complication.

In the most intense varieties which find examples among Europeans and

Americans in intertropical countries, or result from acute mineral

poisoning and from rapidly-progressing cases of acute ulceration of the

intestinal wall, especially in children, there is a sharper and more

violent invasion. The strength is reduced in a very short time, and

there is rapid emaciation; the features assume an anxious expression;

the complexion is leaden or livid; the skin is cold and clammy; the

pulse is small, weak, and rapid; the breath comes quick and short, and

is frequently complicated with hiccough. In the early stages vomiting

occurs, due to a concurrent gastritis; in cases of poisoning vomiting

is incessant.

The pain in the abdomen is intense, and less paroxysmal than in other

forms. The abdomen is tympanitic and excessively tender to the touch,

and the knees are drawn up to relieve the tension of the abdominal

muscles. Thin, black, or reddish stools are passed every few moments.

As the attack progresses the urine is suppressed, the voice becomes

whispering, and collapse is developed. This is marked by cold

extremities, dyspnoea, feeble and finally imperceptible pulse. Death

may end the scene in a few hours or the patient may rally and recover

slowly.

Choleriform diarrhoea occurs chiefly in children during hot weather.

VARIETIES DUE TO SEAT.--The symptoms and progress of acute catarrh of

the intestines present numerous differences depending upon the seat of

the inflammation. The symptomatology already given is that of the most

common form (ileo-colitis), in which the lower part of the ileum and a

considerable portion of the colon are simultaneously involved. Many

cases no doubt occur in which the disease is limited and in which early

recovery is the rule. The pathological anatomy of cases of generalized

catarrh is better known, as they form the bulk of the fatal cases.

I. Acute Duodenitis.--The most common form of duodenitis is that in

which the inflammation spreads by continuity of tissue from the stomach

to the duodenum, as in acute gastric catarrh after a debauch. The

prominence of the gastric symptoms disguises the intestinal lesion,

unless the catarrh, as is frequently the case, extends into and

obstructs the common bile-duct and its branches, and suddenly develops

icterus with clayey stools and altered urine. Besides icterus, a

careful isolation of symptoms will show that some cannot be attributed

to the stomach: there is a dull pain seated in the right hypochondrium,

extending to the right shoulder or shoulder-blade, which is increased

by pressure upon the region of the duodenum. As the gastric symptoms

improve there is no change in the icterus, which continues for some

days or weeks longer. The connection between burns of the integument

and ulcer of the duodenum is well known. Symptoms of perforation, with

death, may be the first sign of this lesion, but vomiting of blood,

icterus, purging of blood, indigestion, and cardialgia occur from

duodenal ulcers.

The typical acute duodenitis described by authors as an independent

{683} affection is of rare occurrence. An epidemic of duodenitis[26]

has been reported where many persons were simultaneously attacked, all

the cases having had the same traits--headache, pain in the line of the

duodenum at the left edge of the right hypochondrium, pain in the first

and second lumbar vertebræ, constipation, jaundice, slow pulse, and

mental depression. Gangrenous inflammation of the duodenum[27] has been

once seen, and produced a chill, a severe sense of weight and pain in

the epigastrium, retching and eructations of gas, tenderness on

pressure, frequent pulse, and high temperature. There was obstinate

constipation, with dyspnoea, death ensuing in a few days. At the

autopsy gangrenous inflammation of the duodenum was found, which ended

abruptly twelve inches from the pylorus. There was a large gall-stone

in the gall-bladder.

[Footnote 26: McGaughey, _Philada. Med. Times_, Aug. 1, 1872, ii. p.

407; also, T. N. Reynolds, _Detroit Clinic_, June 7, 1882, p. 181.]

[Footnote 27: Eskridge, _Philada. Med. Times_, Feb. 15, 1879, ix. p.

239.]

A fatal case of duodenitis is recorded[28] in which the following

symptoms were observed: sudden and severe pain in the right

hypochondrium, increased by pressure; rigors, vomiting and purging of a

green flocculent fluid, and later of blood; jaundice, fever, delirium,

collapse, and death. The pylorus and two-thirds of the duodenal mucous

membrane were much inflamed and the orifice of the bile-duct closed.

[Footnote 28: _Die Krankheiten des Duodenums_, Mayer, quoted by Leube

in _Ziemssen's Cyclopædia_, Am. ed., vol. vii. p. 373.]

II. Acute Ileitis, Acute Jejunitis.--When the ileum, with or without

the jejunum, is the seat of catarrh, diarrhoea may not be present,

provided the inflammation is slight and there is no increase of colon

peristalsis. The symptoms then are borborygmi, pain and fulness about

and below the umbilicus or between it and the right ileum, especially

after eating, and the general symptoms arising from indigestion and

malnutrition. Fever is slight or absent; there are malaise and loss of

strength. The feces give important indications. They contain unaltered

bile and fragments of muscular fibre and starch-granules in excess of

the quantity found in health. An increased quantity of mucus, diffused

evenly in a fluid evacuation, or globules of mucus stained with bile,

or bile-stained epithelium, denote inflammation confined to the small

intestine. A larger amount of indican in the urine than is normally

present is a sign of the same lesion.[29]

[Footnote 29: These conclusions are based upon the results of one

thousand examinations of feces made by H. Nothnägel, and reported in

_Zur Klinik der Darmkrankheiten; Zeitschrift für klin. Medicin_, iv.,

1882, p. 223.]

Intense inflammation of the small intestine may exist without diarrhoea

or other symptoms betokening the real nature of the attack. Flint[30]

mentions having met with three such instances, and Goodhart[31] records

thirteen cases of enteritis with marked lesions in which no diagnosis

had been made before death. Rilliet and Barthez report twenty-four

autopsies in children with intestinal lesions in which no symptoms had

been observed.[32]

[Footnote 30: _Clinical Medicine_, Philada., 1879, p. 280.]

[Footnote 31: _Guy's Hospital Gazette_, Sept., 1878, p. 98 _et seq._]

[Footnote 32: _Maladies des Enfants_, Paris, 1861, tome i. p. 748.]

III. Acute Colitis.--Fifty years ago colitis was synonymous with

enteritis, and not with dysentery, as at a more recent date.[33] The

older {684} signification expressed the fact that inflammation in the

colon is essential to diarrhoea. Later the term was used synonymously

with dysentery.[34]

[Footnote 33: _Journal général de Médecine_, Paris, 1825, t. xci. p.

18.]

[Footnote 34: Tweedie, _System of the Practice of Medicine_, 1841.]

The colon is a conducting tube; the contents are composed of matters

unabsorbed in the small intestines. At first the mass entering the

colon is fluid, but by the gradual absorption of its watery part it

approaches solidity. The discharge from the rectum of a fluid shows

that the propulsion through the large intestine is so rapid that the

process of drying does not take place, or that from inflammation of the

colon there is an excess of fluid transudation from the intestinal

wall. The superficial position of the colon, its great size and length,

expose it to the action of external cold, to blows, etc.

In catarrh limited to the colon there are essentially the same symptoms

as in ileo-colitis, inasmuch as the inflammation of the colon gives to

that form its characteristic features--borborygmi, diarrhoea, and

tympanites. When the disease in the colon preponderates or exists

alone, the pain and tenderness are more superficial and confined to the

line of the large intestine. The distended colon projects and the

abdominal swelling is not so uniform. If the attack is subacute or

mild, the stools contain normal feces mixed with a great deal of mucus;

when the inflammation is in the sigmoid flexure, pure mucus is passed.

Blood mixed with mucus and tenesmus accompany inflammation low down.

Blood may, however, come from intense inflammation of the ascending and

transverse colon without disease of the lower bowel.[35]

[Footnote 35: In a case seen by the writer of colitis terminating

fatally from perforation of the transverse colon this point was

illustrated. A woman aged fifty was taken with diarrhoea in August,

1873. In November the symptoms became worse: tongue dry and red;

abdominal pain; tympanites; frequent stools, ten to seventeen in

twenty-four hours; quantity large, of a yellow or brownish-red color

with floating flakes. General symptoms grew worse; blood in stools from

time to time. November 24, sudden cessation of discharges from the

bowels, and the following day sudden collapse and death. Autopsy:

Descending colon and sigmoid flexure comparatively healthy. Transverse

colon adherent to stomach; deposits of lymph on colon and small

intestines; fluid and feces in the peritoneal cavity. The mucous

membrane of the ascending and transverse colon in a state of black

pulpy disintegration. In the transverse colon the walls were thinned by

ulceration and easily torn; gangrenous appearance of mucous coat;

perforation of the colon wall below greater curvature of the stomach.]

IV. Proctitis.--The rectum may be the seat of simple catarrh, which

differs in its symptoms from catarrh of other portions of the canal. By

many this form is called simple, non-infective dysentery. But as it is

a form of intestinal catarrh, it is right that it should be considered

in connection with colitis. The first indication of its onset is a

frequent desire to go to stool, with an unsatisfied feeling after each

effort. Normal fecal matter is first expelled in solid form, coated

with mucus which may be streaked with blood. Soon, however, the

discharges consist of jelly-like mucus, alone or mixed with blood. A

small quantity of this is passed with tenesmus at short intervals. The

patient complains of a burning feeling in the rectum and a constant and

irresistible desire to strain. The same spasmodic contraction may

involve the bladder.
