Chauliac was particularly interested in the radical cure of hernia, and he discusses six different operations for this purpose. Gurlt points out that Chauliac's criticism of these operations is quite modern in its viewpoint. He declared that practically the object of radical operations for hernia is to produce a strong, firm tissue support over the ring through which the cord passes, so that the intestines cannot descend through it. It is rather interesting to find that the surgeons of this time tried to obliterate the canal by means of the cautery, or inflammation-producing agents--arsenic and the like--a practice that recalls some methods still used more or less irregularly. They also used gold wire as a support; it was to be left in the tissues, and was supposed to protect and strengthen the closure of the ring. At this time all these operations for the radical cure of hernia involved the sacrifice of the testicle, because the old surgeons wanted to obliterate the ring completely, and thought this the easiest way. Chauliac criticizes the operation in this respect, but says that he has "seen many cases in which men possessed of but one testicle have procreated, and this is a problem where the lesser of two evils is to be chosen." While he discussed hernia operations so freely, the great French surgeon did not believe that everyone who suffered from a hernia ought to be submitted to an operation. He quite agreed with Mondeville who, in the preceding generation, declared that many operations for hernia were done not for the benefit of the patient but for the benefit of the surgeon--a mode of expression that is likely to strike a sympathetic chord in some physicians' minds even at the present time. Chauliac's rule was that no operation should be attempted unless the patient's life was put in danger by the hernia, but that a truss should be worn to retain it. He emphasized that trusses should not be made according to rule, but must be adapted to each individual, and he invented several forms of trusses himself. He developed the method of taxis by which hernias might be reduced, suggested an exaggerated Trendelenburg position for operations for hernia and for the manipulations necessary for the reduction of hernia.
