The impact of a chronic disease such as inflammatory bowel disease (IBD) on sexual functioning and body image can significantly impair the quality of life of patients. This review considers the sexual and fertility aspects of IBD patients and their daily management. Modern IBD healthcare management should include appropriate communication on sexuality and consider psychological, physiological, and biological issues. Patients with IBD have less children than the general population, and voluntary childlessness is frequent. The most influential factors reported by IBD patients who experience fertility alteration are psychological and surgery-related problems. Pregnancy is a major concern for patients, and any pregnancy for IBD patients should be closely followed-up to keep the chronic disease in a quiescent state. Preconceptional consultation is of great help.

To establish consensual definitions of anoperineal lesions of Crohn’s (APLOC) disease and assess interobserver agreement on their diagnosis between experts. METHODSA database of digitally recorded pictures of APLOC was examined by a coordinating group who selected two series of 20 pictures illustrating the various aspects of APLOC. A reading group comprised: eight experts from the Société Nationale Française de Colo Proctologie group of study and research in proctology and one academic dermatologist. All members of the coordinating and reading groups participated in dedicated meetings. The coordinating group initially conducted a literature review to analyse verbatim descriptions used to evaluate APLOC. The study included two phases: establishment of consensual definitions using a formal consensus method and later assessment of interobserver agreement on the diagnosis of APLOC using photos of APLOC, a standardised questionnaire and Fleiss’s kappa test or descriptive statistics. RESULTSTerms used in literature to evaluate visible APLOC did not include precise definitions or reference to definitions. Most of the expert reports on the first set of photos agreed with the main diagnosis but their verbatim reporting contained substantial variation. The definitions of ulceration (entity, depth, extension), anal skin tags (entity, inflammatory activity, ulcerated aspect), fistula (complexity, quality of drainage, inflammatory activity of external openings), perianal skin lesions (abscess, papules, edema, erythema) and anoperineal scars were validated. For fistulae, they decided to follow the American Gastroenterology Association’s guidelines definitions. The diagnosis of ulceration (κ = 0.70), fistulae (κ = 0.75), inflammatory activity of external fistula openings (86.6% agreement), abscesses (84.6% agreement) and erythema (100% agreement) achieved a substantial degree of interobserver reproducibility. CONCLUSIONThis study constructed consensual definitions of APLOC and the
