SURGICAL TREATMENT OF HYDATID TUMOURS. 187 



of course, been previously emptied as nearly as pos- 

 sible of its contents ; if symptoms of iodism make 

 their appearance, they soon disappear again, and in 

 favourable cases no bad complications whatever need 

 be feared. 



Dr. Davaine gives an analysis of fourteen cases 

 treated by the use of iodised injections. In eight of 

 these it formed the principal part of the treatment ; 

 in four of the eight cases, the cure was due to the 

 employment of the injection ; on three occasions the 

 injection was unattended with success, and incision 

 was subsequently performed ; in one case death fol- 

 lowed the operation, but it was attributable to other 

 causes than the plan of treatment which was adopted. 

 In the other six cases the injections were only em- 

 ployed as accessory to other methods of treatment, — 

 twice after repeated puncture, once after incision into 

 the tumour, and three times after the apphcation of 

 caustic ; good results occurred in three of these 

 cases ; in one death supervened, and the subsequent 

 history of the other two cases is insufficient to show 

 what the final results of the operation were. 



Alcoholic injections have been employed in two 

 cases of hydatids with perfect success. In one of 

 these, a case of hydatids of the liver, caustic potash 

 was first applied, and the cicatrix was afterwards 

 incised, so as to Hberate a considerable number of 

 hydatids ; the operator, M. Jobert, then injected a 

 mixture of alcohol and distilled water into the cyst, 

 and allowed a female catheter to remain in the wound 

 in order to facihtate the escape of the fluid and of 

 the hydatids ; hydatids continued to be discharged 

 through the opening for two months after the
