Description
Khadeeja Iftikhar and co-authors write a 2026 letter commenting on an ultrasound study of blood flow in hemorrhoidal disease. The original study used Doppler ultrasound, a sound-wave blood flow test, through the perineum, and found faster peak flow in advanced hemorrhoid grades. The letter writers praise the non-invasive approach and its support for a vascular contribution to the disease.
They then raise five cautions. A one-time snapshot cannot show whether flow changes cause the disease, and a single unblinded operator may bias readings. Wide age ranges and controls drawn from surgical clinics may skew results, and key factors like body weight and constipation went unadjusted. They also suggest adding more flow measures and validating the method against standard exams.
