Who is a Candidate?
Doctors usually grade hemorrhoids on a scale of 1 to 4. Patients with troublesome hemorrhoids of grade 1 or 2 are candidates for sclerotherapy. Grade 1 hemorrhoids stay within the anal canal but may bleed frequently and be painful, while grade 2 may protrude beyond the anal canal during straining but return inside after straining stops; grade 2 may bleed frequently and be painful. Grade 3 protrudes outside the anal canal but can be manually pushed back in, while Grade 4 cannot be manually returned to the anal canal. Grades 3 and 4 generally require stapling or surgical treatment.
Safety of Sclerotherapy
In general, the procedure is considered to be extremely safe, even for patients with comorbidities like heart disease and diabetes. After each injection, patients may experience some mild bleeding and discomfort for a few days.
