In all cases of large growths, whether the patient is in a comparative state of ease or not, a similar preparatory treatment before operation will shrinken the tumors and lessen the tendency to local congestion and pain. Sulphur should not be taken within two or three days of operation since it continues its action about that length of time after dosage; but the bowels should be sufficiently evacuated previously to enable them to be held for four days afterwards, by any agreeable cathartic, or by _flushing of the colon_. This will be unnecessary in the treatment of small growths. The same course should be pursued to expose the tumors for operation, as was named under the head of examination. In some instances, where the tumors are not very large but exceedingly irritable (arterial), it might be quite difficult, even though the bowel be partially prolapsed, to expose them sufficiently for a good operation. In such event, paint the protrusion with a 5 per cent. solution of cocaine and allow the patient to sit, for a few moments, over a vessel containing a small quantity of steaming hot water. This will engorge the tumors, relax and materially aid in handling the parts. As a precautionary measure in _all operations by injection_, to prevent the medicine from extending too deeply into the tissue of the gut by gravity, or the overflow from running down on the outside of the pile and over the bowel, let the patient lie on the side opposite to the tumor to be treated, so that the preparation will gravitate to the apex rather than its base of attachment. [Illustration: FIG. 3.] Smear vaseline on the opposite side of the bowel and anus and over any piles that may show on that side, which, as the patient is now placed, are on the lower or under side and will catch any and all waste and overflow of medicine. As a further protection pack or hold absorbent cotton underneath the tumor being operated upon. If the tumor be small and partially obscured, the end of the finger may be held back of it to act as a counterforce while introducing the needle; or a double, slide tenaculum may be used to pull and hold it down for the same purpose, being careful not to remove the tenaculum when once applied until after the operation, as the least prick or scratch of a hemorrhoid will cause a free flow of blood and greatly hinder the sight when it is desirable to watch the action of the injection compound.
