Although sclerotherapy, first advocated by Mitchell in 1871, has been used often in hemorrhoids, it is rarely performed in the United States.The purpose of sclerotherapy is to scar the submucosa, resulting in atrophy of the tissue injected and scarification with fixation of the hemorrhoidal complex within its normal location in the anal canal. A variety of solutions have been advocated, although it appears that sodium morrhuate and sodium tetradechol sulfate predominate. This modality is most effective in situations with minimal enlargement of hemorrhoidal complexes where the primary complaint is bright red rectal bleeding.
The procedure is performed with the patient in the left lateral decubitus position. An anoscope is inserted to clearly identify the symptomatic complex, and a 25-gauge spinal needle is used to instill the sclerosant into the submucosal space . The syrine should be aspirated before injection to avoid a direct intravascular injection. Typically, 1 to 2 ml of sclerosant is adequate. The surgeon can inject as many locations as desired because the procedure is essentially painless. It is important, however, not to circumferentially inject the anal canal, because this may induce stricture formation.
