614 TREATMENT OF TUMOURS IN THE RECTUM. 



drawn well forward, cither with forceps or by passing a tape through 

 it, and dissected out without injuring the rectal mucous membrane. 

 Tumours in the rectum itself are extirpated either by ligation or 

 the ecraseur. Polypi may be removed by traction, or by torsion. 

 If the pedicle is thick it should be ligatured and after an interval 

 of two or three days the tumour can be safely removed by torsion. 

 Cysts are treated by puncture followed by injection with solution 

 of iodine ; or they may be opened widely or partially excised. Serious 

 bleeding is rare, and such as occurs can be controlled by cold clysters 

 or tampons. 



Frey states having noted in the horse, close in front of the anus, two 

 sarcomata (?) which produced prolapsus ani. Kohne removed from the 

 rectum of a horse by ligature a polypus whose seat was 4 to 5 inches in 

 front of the anus, through which it protruded during defaecation. In a 

 second horse Kohne removed with the ecraseur a polypus the size of a man's 

 fist, which lay about 16 inches forward from the anus. Stockfleth states 

 having seen cancer of the rectum in old cattle. Siedamgrotzky discovered 

 in a gelding a cyst as large as a man's fist lying on the lower wall of the 

 rectum 6 inches from the anus ; it discharged a clear fluid on perforation 

 with the trocar. After injecting tincture of iodine, healing occurred. 

 A similar case is described by Hierholzer. 



Truelsen removed from the rectum of a foal several polypi, which lay 

 about two hands'-breadths from the anus, and had repeatedly caused 

 constipation and colic. An improvised ecraseur was constructed of a 

 cannula and wire, with which Truelsen removed the growth, and effected 

 a cure. 



Frohner removed from a horse a serous cyst which had its seat on the 

 upper wall of the rectum about 4 inches from the anus ; he applied a silk 

 ligature and snipped off the growth with scissors. Teetz, in a case in the 

 horse, laid open the cyst and obtained healing. 



Haemorrhoids, or varices of the rectum, only occasionally occur in 

 horses, cattle, or dogs. Frequently the condition due to proctitis, con- 

 gestion of the mucous membrane, or inflammatory swelling of the anal 

 glands in dogs, is mistaken for haemorrhoids. But dogs sometimes suffer 

 from varicose veins inside or outside the anal sphincter, and if not speedily 

 relieved, abrasion, ulceration, fissure or sinus formation may ensue. 

 Haemorrhoids cause much irritation, hinder defalcation, are painful and 

 often associated with constipation, in old dogs with liver or cardiac disease, 

 and frequently they bleed during the passage of faeces. Treatment is 

 both general and local. In most cases regular exercise and laxative diet 

 are beneficial, while attention is given to the state of the liver, heart and 

 bowels. Locally, injections of warm water and glycerine, or olive oil, 

 are indicated. Abrasions and ulcers must be cleansed and disinfected ; 

 and to allay the pruritus, which is often troublesome, a pomade, containing 

 belladonna and cocaine, may be applied. In some cases precipitated 

 sulphur forms the best dressing. Excision of the haemorrhoid, by the 

 knife or thermocautery, may be required. Bleeding is controlled by 

 inserting in the rectum a plug of gauze saturated with adrenalin solution. 



Carougeau successfully operated on a mass of varicose veins involving 

 the rectum and lower surface of the tail in a horse.
