The Association of Coloproctology of Great Britain and Ireland guideline on the management of anal fissure.

[AIM] The management of anal fissure: ACPGBI position statement was written 15 years ago. [KLR Cross et al., Colorectal Dis, 2008]. Our aim was to update the guideline and provide recommendations on the most effective treatment for patients with anal fissures utilising a multidisciplinary, rigorous guideline methodology.

[METHODS] The development process consisted of six phases. In phase 1 we defined the scope of the guideline. The patient population included patients with acute and chronic anal fissure. The target group was all practitioners (primary and secondary care) treating patients with fissures and, in addition, healthcare workers and patients who desired information regarding fissure management. In phase 2 we formed a guideline development group (GDG) including a methodologist. In phase 3 review questions were formulated, using a reversed PICO process, starting with possible recommendations based on the GDG's knowledge. In phase 4 a comprehensive literature search focused on existing systematic reviews addressing each review question, supplemented by more recent studies if appropriate. In phase 5 data were extracted from the included papers and checked by the GDG. If indicated, meta-analysis of systematic review data was updated by the GDG. During phase 6 the GDG members decided what recommendations could be made based on the evidence in the literature and strength of the recommendation was assessed using 'grade'.

[RESULTS] This guideline is divided into two sections: Primary care which includes (i) diagnosis; (ii) basic treatment; (iii) topical treatment; and secondary care which includes (iv) botulinum toxin therapy; (v) surgical intervention and (vi) special situations (including pregnancy and breast-feeding patients, children, receptive anal intercourse and low-pressure fissures). A total of 23 recommendations were formulated. A new term clinically healed was described by the GDG.

[CONCLUSION] This guideline provides an up-to-date evidence-based summary of the current knowledge of the management of anal fissure and may serve as a useful guide for clinicians as well as a potential reference for patients.
