When the occlusion of the common bile-duct is caused by an organic tumour, no treatment of ours can be expected to remove the obstacle, and sooner or later the patient is carried to an untimely grave. Our efforts of relief in such a case ought therefore to be directed to another channel; and here, in order to give the sufferer at least some chance of recovery, even although it be little better than a forlorn hope, I cannot refrain from recommending, in cases of permanent occlusion of the duct, in which there is great distension of the gall-bladder, the establishment of an artificial biliary fistula. Were this done, the patient would be placed, as {125} nearly as possible, in the same condition as an animal in which the operation has been performed for physiological purposes, and, we might almost hope, with an equally favourable result, at least, in as far as the biliary functions are concerned. In the first place, we would have removed all the derangements resulting from the interruption to the flow of bile, and consequent upon the distension of the ducts. In the second place, we would have obviated the danger arising from the poisonous effects of the re-absorbed bile, which the experiments previously cited (page 98) show are of no trifling nature; and, lastly, we would only require to combat the evils arising from the absence of the biliary secretion in the digestive process, which, as was before said, can to a certain extent be overcome by giving an additional quantity of food, and paying attention to the bowels. In these remarks I have omitted taking into consideration the effects that might arise from the tumour, or other obstructing cause to the biliary secretion, for these would in no way be directly influenced by the establishment of the biliary fistula.
