Perianal Crohn's Disease.

This article provides an overview of the principles in the evaluation and management of perianal Crohn's disease (CD). Manifestation-specific treatment is addressed including abscess, fistula, skin tags, hemorrhoids, fissure, ulcers, strictures, ano-, and rectovaginal fistulas as well CD-associated hidradenitis suppurativa.

Tratamiento de la fisura anal: algoritmo de actuación. Documento de consenso de la Asociación Española de Coloproctología y la Sección de Coloproctología de la Asociación Española de Cirujanos / Treatment algorithm for anal fissure. Consensus document of the Spanish Association of Coloproctology and the Coloproctology Division of the Spanish Association of Surgeons

Desde la Asociación Española de Coloproctología y la Sección de Coloproctología de la Asociación Española de Cirujanos se propone un documento de consenso sobre el algoritmo de actuación en el tratamiento de la fisura anal que pueda ser de utilidad en la toma de decisiones. En él se expone la actualidad en el tratamiento conservador, médico y quirúrgico, finalizando con un algoritmo de recomendación ante una fisura anal. La metodología utilizada ha sido: creación de un grupo de expertos, búsqueda en PubMed, MEDLINE y Biblioteca Cochrane de las publicaciones de los últimos 10 años sobre fisura anal, presentación en la XXI Reunión Nacional de la Fundación Asociación Española de Coloproctología 2017 con votación de cada conclusión entre los asistentes, y revisión por el comité científico de la Asociación Española de Coloproctología

The Spanish Association of Coloproctology and the Coloproctology Division of the Spanish Association of Surgeons propose this consensus document with a treatment algorithm for anal fissure that could be used for decision making. Non-surgical therapy and surgical treatment of anal fissure are explained, and the recommended algorithm is provided. The methodology used was: creation of a group of experts; search in PubMed, MEDLINE and the Cochrane Library for publications from the last 10 years about anal fissure; presentation at the 21st National Meeting of the Spanish Association of Coloproctology Foundation 2017 with voting for/against each conclusion by the attendees and review by the scientific committee of the Spanish Association of Coloproctology

Controlled dose delivery in topical treatment of anal fissure: pilot study of a new paradigm.

PURPOSE: Topical nitroglycerin has been widely used as a means for avoiding surgery in patients with anal fissure. However, nitroglycerin has not been universally accepted for this application because of inconsistency of efficacy and side effects. This study compares conventional digital application with precise intra-anal dosing of nitroglycerin using a specialized dose-delivery device and anal cannula. METHODS: Twenty-six consecutive patients (13 males) with chronic anal fissure and no previous treatment were randomly allocated to receive 0.75 ml of 0.3 percent nitroglycerin ointment (2.25 mg nitroglycerin) t.i.d. intra-anal using the cannula (Group A) or perianally with the gloved finger (Group B). Nitroglycerin dosage was controlled in Group A by the dose-delivery device connected to the cannula and by single-dose preloaded syringes in Group B. RESULTS: Anal manometry: pressure reduction after application of nitroglycerin was 47 +/- 18.6 in Group A and 20.7 +/- 13.4 percent in Group B (P < 0.01). Headaches were reported by 1 of 10 patients in Group A and 10 of 12 patients in Group B (P = 0.0027). Seven patients of Group B had to be crossed to intra-anal treatment as a result of intensity of headaches. Pain relief was noted by 8 of 10 and 9 of 12 patients in Groups A and B, respectively (P = 0.6). Sphincterotomy was required in only 13.6 percent of all patients. CONCLUSIONS: Controlled intra-anal dosing of topical nitroglycerin produces a significantly greater reduction in sphincteric pressure and lower incidence of headaches than with perianal administration of the same dose of ointment. These results suggest a new paradigm for increasing safety and efficacy of dose-dependent prescription anal topical medications.

Manometric study of topical sildenafil (Viagra) in patients with chronic anal fissure: sildenafil reduces anal resting tone.

PURPOSE: Topical therapies for anal fissure have largely focused on nitric-oxide donors (e.g., nitroglycerin), sometimes with undesirable side effects or inconsistent benefits. Topical phosphodiesterase inhibitors have theoretical merit but have never been reported in treatment of anal fissure. This article describes manometric analysis of the effects of a phosphodiesterase-5 inhibitor, topical sildenafil (Viagra) in 19 consecutive patients with chronic anal fissure with no previous treatment history. METHODS: Station pullthrough manometry was performed with patients in the left-lateral position. Maximum resting pressure (MRP1) was recorded, and 0.75 ml of 10 percent sildenafil was then instilled in the anal canal. Maximum resting pressure was repeated at the same distance from the anal verge. Thereafter, pressure was measured continuously. Time for initial relaxation (T1) and time to maximal relaxation (T2) were recorded. Average resting pressure (MRP2) was calculated. Results were analyzed by Student's t-test. RESULTS: Topical administration of 10 percent sildenafil was accompanied by significant reduction in anal sphincter pressure (18 percent; P < 0.01). Only one patient failed to respond. Average onset of action was less than three minutes, with maximum effect one minute later. MRP1: 119.3 +/- 18.7 cmH(2)O. MRP2: 97.8 +/- 21.3 cmH(2)O. MRP2 < MRP1, P < 0.01. MRP M vs. F, ns. T1: 168 +/- 67 seconds (M = 210 +/- 72, F = 130 +/- 53, P < 0.02). T2: 230 +/- 78 seconds (M = 271 +/- 63, F = 183 +/- 75, P < 0.02). Mild-to-moderate anal discomfort was reported by 26 percent of patients. No headaches or other side effects were reported. CONCLUSIONS: Topical administration of a phosphodiesterase-5 inhibitor (sildenafil, Viagra) significantly reduces anal sphincter pressure in patients with chronic anal fissure. A beneficial effect of nitric oxide on the spastic anal sphincter has been demonstrated previously. This study confirms that this effect need not be derived solely from nitric oxide donors. New therapeutic avenues for treatment of anal fissure through indirect enhancement of nitric oxide activity are suggested.
