The fatality of rupture of the spleen is quite high. Out of 83cases of injury to this organ collected by Elder, and quoted by MacCormac, only 11 recovered; but the mortality is less in punctured or incised wounds of this organ, the same authorities mentioning 29 recoveries out of 35 cases. In his "Surgery" Gooch says that at the battle of Dettingen one of Sir Robert Rich's Dragoons was left all night on the field, weltering in his blood, his spleen hanging out of his body in a gangrenous state. The next morning he was carried to the surgeons who ligated the large vessels, and extirpated the spleen; the man recovered and was soon able to do duty. In the Philosophical Transactions there is a report of a man who was wounded in the spleen by a large hunting-knife. Fergusson found the spleen hanging from the wound and ligated it. It separated in ten days and the patient recovered.
Williams reports a stab-wound of the spleen in a negro of twenty-one. The spleen protruded, and the protruding part was ligated by a silver wire, one-half of the organ sloughing off;the patient recovered. Sir Astley Cooper mentions a curious case, in which, after vomiting, during which the spleen was torn from its attachments, this organ produced a swelling in the groin which was supposed to be a hernia. The vomiting continued, and at the end of a week the woman died; it was then found that the spleen had been turned half round on its axis, and detached from the diaphragm; it had become enlarged; the twist interrupted the return of the blood. Portal speaks of a rupture of the spleen simply from engorgement. There was no history of a fall, contusion, or other injury. Tait describes a case of rupture of the spleen in a woman who, in attempting to avoid her husband's kick, fell on the edge of the table. There were no signs of external violence, but she died the third day afterward. The abdomen was found full of blood, and the spleen and peritoneal covering was ruptured for three inches.
Splenectomy, excision of the spleen, has been performed a number of times, with varying results, but is more successful when performed for injury than when for disease. Ashhurst has tabulated a total of 109 operations, 27 having been for traumatic causes, and all but five having terminated successfully; of 82operations for disease, only 32 recovered. Vulpius has collected 117 cases of splenectomy, with a death-rate of 50 per cent. If, however, from these cases we deduct those suffering with leukocythemia and lardaceous spleen, in which the operation should not be performed, the mortality in the remaining 85 cases is reduced to 33 per cent. Terrier speaks of splenectomy for torsion or twisting of the pedicle, and such is mentioned by Sir Astley Cooper, who has found records of only four such cases.
Conklin reports a successful case of splenectomy for malarial spleen, and in reviewing the subject he says that the records of the past decade in operations for simple hypertrophy, including malaria, show 20 recoveries and eight deaths. He also adds that extirpation in cases of floating or displaced spleen was attended with brilliant results. Zuccarelli is accredited with reporting two cases of splenectomy for malarial spleen, both of which recovered early. He gives a table of splenectomies performed in Italy, in which there were nine cases of movable spleen, with two deaths; eight cases of simple hypertrophy, with three deaths; 12cases of malarial spleen, with three deaths; four cases of leukemia and pseudoleukemia, with two deaths. In his experiments on rabbits it was proved by Tizzoni, and in his experiments on dogs, by Crede, that an individual could live without a spleen;but these observations were only confirmatory of what had long been known, for, in 1867, Pean successfully removed a spleen from a woman of twenty. Tricomi reports eight cases in which he had extirpated the spleen for various morbid conditions, with a fortunate issue in all but one. In one case he ligated the splenic artery. In The Lancet there is an account of three recent excisions of the spleen for injury at St. Thomas Hospital in London, and it is added that they are among the first of this kind in Great Britain.
Abnormalities of Size of the Spleen.--The spleen may be extremely small. Storck mentions a spleen that barely weighed an ounce;Schenck speaks of one in the last century that weighed as much as 20 pounds. Frank describes a spleen that weighed 16 pounds; there is another record of one weighing 15 pounds. Elliot mentions a spleen weighing 11 pounds; Burrows one, 11 pounds; Blasius, four pounds; Osiander, nine pounds; Blanchard, 31 pounds; Richardson, 3 1/2 pounds; and Hare, 93 ounces.
The thoracic duct, although so much protected by its anatomical position, under exceptional circumstances has been ruptured or wounded. Kirchner has collected 17 cases of this nature, two of which were due to contusions of the chest, one each to a puncture, a cut, and a shot-wound, and three to erosion from suppuration. In the remaining cases the account fails to assign a definite cause. Chylothorax, or chylous ascites, is generally a result of this injury. Krabbel mentions a patient who was run over by an empty coal car, and who died on the fifth day from suffocation due to an effusion into the right pleural cavity. On postmortem examination it was found that the effusion was chyle, the thoracic duct being torn just opposite the 9th dorsal vertebra, which had been transversely fractured. In one of Kirchner's cases a girl of nine had been violently pushed against a window-sill, striking the front of her chest in front of the 3d rib. She suffered from pleural effusion, which, on aspiration, proved to be chyle. She ultimately recovered her health. In 1891Eyer reported a case of rupture of the thoracic duct, causing death on the thirty-eighth day. The young man had been caught between a railroad car and an engine, and no bones were broken.
