Imperforate Anus. Cases in which the anus is imperforate or the rectum ends in a blind pouch are occasionally seen. In some instances the rectum is entirely absent, the colon being the termination of the intestinal tract. There are cases on record in which the rectum communicated with the anus solely by a fibromuscular cord. Anorectal atresia is the ordinary imperforation of the anus, in which the rectum terminates in the middle of the sacral cavity. The rectum may be deficient from the superior third of the sacrum, and in this position is quite inaccessible for operation.

A compensatory coalition of the bowel with the bladder or urethra is sometimes present, and in these cases the feces are voided by the urinary passages. Huxham mentions the fusion of the rectum and colon with the bladder, and similar instances are reported by Dumas and Baillie. Zacutus Lusitanus describes an infant with an imperforate membrane over its anus who voided feces through the urethra for three months. After puncture of the membrane, the discharge came through the natural passage and the child lived; Morgagni mentions a somewhat similar case in a little girl living in Bologna, and other modern instances have been reported. The rectum may terminate in the vagina. Masters has seen a child who lived nine days in whom the sigmoid flexure of the colon terminated in the fundus of the bladder. Guinard pictures a case in which there was communication between the rectum and the bladder. In Figure 140 a represents the rectum; b the bladder; c the point of communication; g shows the cellular tissue of the scrotum.

There is a description of a girl of fourteen, otherwise well constituted and healthy, who had neither external genital organs nor anus. There was a plain dermal covering over the genital and anal region. She ate regularly, but every three days she experienced pain in the umbilicus and much intestinal irritation, followed by severe vomiting of stercoraceous matter; the pains then ceased and she cleansed her mouth with aromatic washes, remaining well until the following third day. Some of the urine was evacuated by the mammae. The examiners displayed much desire to see her after puberty to note the disposition of the menstrual flow, but no further observation of her case can be found.

Fournier narrates that he was called by three students, who had been trying to deliver a woman for five days. He found a well-constituted woman of twenty-two in horrible agony, who they said had not had a passage of the bowels for eight days, so he prescribed an enema. The student who was directed to give the enema found to his surprise that there was no anus, but by putting his finger in the vagina he could discern the floating end of the rectum, which was full of feces. There was an opening in this suspended rectum about the size of an undistended anus. Lavage was practiced by a cannula introduced through the opening, and a great number of cherry stones agglutinated with feces followed the water, and labor was soon terminated. The woman afterward confessed that she was perfectly aware of her deformity, but was ashamed to disclose it before. There was an analogue of this case found by Mercurialis in a child of a Jew called Teutonicus.

Gerster reports a rare form of imperforate anus, with malposition of the left ureter, obliteration of the ostia of both ureters, with consequent hydronephrosis of a confluent kidney. There was a minute opening into the bladder, which allowed the passage of meconium through the urethra. Burge mentions the case of what he calls "sexless child," in which there was an imperforate anus and no pubic arch; the ureters discharged upon a tumor the size of a teacup extending from the umbilicus to the pubes. A postmortem examination confirmed the diagnosis of sexless child.

The Liver. The Ephemerides, Frankenau, von Home, Molinetti, Schenok, and others speak of deficient or absent liver. Zacutus Lusitanus says that he once found a mass of flesh in place of the liver. Lieutaud is quoted as describing a postmortem examination of an adult who had died of hydropsy, in whom the liver and spleen were entirely missing. The portal vein discharged immediately into the vena cava; this case is probably unique, as no authentic parallel could be found.

Laget reports an instance of supernumerary lobe in the liver. Van Buren describes a supernumerary liver. Sometimes there is rotation, real or apparent, caused by transposition of the characteristics of the liver. Handy mentions such a case. Kirmisson reports a singular anomaly of the liver which he calls double displacement by interversion and rotation on the vertical axis. Actual displacements of the liver as well as what is known as wandering liver are not uncommon. The operation for floating liver will be spoken of later.

Hawkins reports a case of congenital obliteration of the ductus communis choledochus in a male infant which died at the age of four and a half months. Jaundice appeared on the eighth day and lasted through the short life. The hepatic and cystic ducts were pervious and the hepatic duct obliterated. There were signs of hepatic cirrhosis and in addition an inguinal hernia

The Gall-Bladder. Harle mentions the case of a man of fifty, in whom he could find no gall-bladder; Patterson has seen a similar instance in a men of twenty-five. Purser describes a double gall-bladder.

The spleen has been found deficient or wanting by Lebby, Ramsay, and others, but more frequently it is seen doubled. Cabrolius, Morgagni, and others have found two spleens in one subject; Cheselden and Fallopius report three; Fantoni mentions four found in one subject; Guy-Patin has seen five, none as large as the ordinary organ; Hollerius, Kerckringius, and others have remarked on multiple spleens. There is a possibility that in some of the cases of multiple spleens reported the organ is really single but divided into several lobes. Albrecht mentions a case shown at a meeting of the Vienna Medical Society of a very large number of spleens found in the mesogastrium, peritoneum, on the mesentery and transverse mesocolon, in Douglas' pouch, etc. There was a spleen "the size of a walnut" in the usual position, with the splenic artery and vein in their normal position. Every one of these spleens had a capsule, was covered by peritoneum, and exhibited the histologic appearance of splenic tissue. According to the review of this article, Toldt explains the case by assuming that other parts of the celomic epithelium, besides that of the mesogastrium, are capable of forming splenic tissue. Jameson reports a case of double spleen and kidneys. Bainbrigge mentions a case of supernumerary spleen causing death from the patient being placed in the supine position in consequence of fracture of the thigh. Peevor mentions an instance of second spleen. Beclard and Guy-Patin have seen the spleen congenitally misplaced on the right side and the liver on the left; Borellus and Bartholinus with others have observed misplacement of the spleen.
