| الوصف: | Background: Increased maximum resting anal pressures (MRAP) have been found in patients with large prolapsed hemorrhoids undergoing hemorrhoidectomy, but their pathogenic role is controversial especially in view of the sphincteric damage that occurs with open and stapled procedures. This prospective randomized clinical trial was conducted to compare anal pressure changes in early symptomatic hemorrhoidal disease before and after successful treatment with band ligation or injection sclerotherapy, and to compare these pressures with those in normal asymptomatic controls. Methods: 32 patients with symptomatic grade II hemorrhoids were randomized to treatment with either band ligation or injection sclerotherapy. Anal manometry was done before treatment and 8 weeks after completion of treatment, and compared with 20 normal age-matched controls. Results: The pretreatment values in both study groups were similar to each other (69.38 cm H2O, 95% CI 58.67–80.08, vs. 67.75 cm H2O, 95% CI 56.86–78.64; p = 0.790), but were significantly higher (p = 0.0001 in both groups) than in the controls (45.25 cm H2O, 95% CI 38.36–52.14). After successful completion of treatment, there was a highly significant drop in the MRAP in both study groups (p = 0.0001 in group A, and p = 0.001 in group B) reaching normal values. Conclusions: Our study shows that even in early-stage hemorrhoids, the anal pressures are significantly raised, but after successful treatment with band ligation or injection sclerotherapy, these pressures return to normal, showing that they do not play a pathogenic role but are secondary to the congested hemorrhoidal cushions. |
