Red hot chili pepper and hemorrhoids: The explosion of a myth: Results of a prospective, randomized, placebo-controlled, crossover trial

PURPOSE: Spicy foods are appreciated by a large part of the world population but have been blamed for causing hemorrhoids or exacerbating their symptoms, although no epidemiologic studies have been performed supporting this hypothesis. In this double-blind, randomized, placebo-controlled, crossover trial, we have studied the effects of a single dose of red hot chili pepper on the hemorrhoidal symptoms. METHODS: Fifty patients with second-degree and third-degree symptomatic hemorrhoids were randomly assigned to take a capsule containing red hot chili powder or placebo during lunch, scoring five hemorrhoidal symptoms (bleeding, swelling, pain, itching, and burning) on a visual analog scale. After one week, crossover treatment was administered according to the same methodology. Other treatments and foods potentially related with anorectal symptoms were discontinued during the study periods. RESULTS: Patients assigned low scores to their hemorrhoidal symptoms before the study and the scores remained unchanged during the 48 hours after both placebo and chili pepper treatment, the latter showing no statistically significant effects. CONCLUSIONS: There is no scientific evidence that a spicy meal based on red hot chili pepper may worsen hemorrhoidal symptoms and, therefore, there is no reason to prevent these patients from occasionally enjoying a spicy dish if they so wish

GLYCERYLTRINITRATE FOR CHRONIC ANAL FISSURE: HEALING OR HEADACHE? Results of a multicentric randomized placebo-controlled trial

Internal anal sphincterotomy for treating chronic anal fissure can irreversibly damage anal continence. Reversible chemical sphincterotomy may be achieved by anal application of glyceryl trinitrate ointment (nitric oxide donor), which has been reported to heal the majority of patients with anal fissure by inducing sphincter relaxation and improving anodermal blood flow. This trial aimed to further clarify the role of glyceryl trinitrate in the treatment of chronic anal fissure. METHODS: A total of 132 consecutive patients from nine centers were randomly assigned to receive 0.2 percent glyceryl trinitrate ointment or placebo twice daily for at least four weeks. The severity of pain and maximum anal resting pressure were measured before and after one week of treatment. Anodermal blood flow was measured before and after application of glyceryl trinitrate or placebo in ten patients. RESULTS: The study was completed by 119 patients (59 glyceryl trinitrate and 60 placebo), matched for gender, age, duration of symptoms, duration of treatment, site of fissure, previous attempts to treat, pain score, and maximum anal resting pressure. Twenty-nine patients (49.2 percent) healed after glyceryl trinitrate and 31 patients (51.7 percent) healed after placebo (P = not significant). Pain score fell significantly in both groups, in addition to maximum anal resting pressure. Anodermal blood flow improved significantly in seven patients receiving glyceryl trinitrate, but not in the three receiving placebo. Twenty-three patients (33.8 percent) experienced headache and 4 (5.9 percent), orthostatic hypotension after glyceryl trinitrate. CONCLUSION: This trial fails to demonstrate any superiority of topical 0.2 percent glyceryl trinitrate treatment vs. a placebo, although the effects of glyceryl trinitrate on anodermal blood flow and sphincter pressure are confirmed. This finding, together with the high incidence of side-effects, should discourage the use of this treatment as a substitute for surgery in chronic anal fissur
