Цель данного обзора – суммировать все известные на сегодняшний день данные о функциональных запорах (ФЗ) у детей и понять, какие вопросы до сих пор бросают вызов врачам касательно эпидемиологии, патофизиологии, диагностики и лечения ФЗ. Несмотря на то что ФЗ – довольно часто встречающаяся проблема, их распространенность в мире неизвестна, поскольку эпидемиологические данные по некоторым регионам отсутствуют. Другая проблема заключается в том, что данные о распространенности очень разнятся, так как используются разные методы исследований и возрастные группы. Механизмы развития ФЗ до сих пор до конца не известны, однако возможно влияние многих факторов. Волевое удержание стула считается главной причиной ФЗ у детей дошкольного и школьного возраста. Генетическая предрасположенность также вероятно играет роль, поскольку у многих пациентов имеется соответствующий семейный анамнез, тем не менее генетические мутации, связанные с ФЗ, не выявлены. За последние годы было предложено несколько критериев диагностики ФЗ у детей школьного и дошкольного возраста. В 2016 г. были опубликованы Римские критерии IV. В сравнении с Римскими критериями III в последней редакции исключены 2 диагностических критерия у детей до 4 лет, у которых используются подгузники. Помимо тщательного сбора анамнеза и осмотра, другие исследования, такие как абдоминальная рентгенография, ультразвуковое исследование толстой кишки, исследование времени толстокишечного транзита, ректальная биопсия и манометрия толстой кишки, не рекомендуются в рутинной практике. Что касается лечения, руководства рекомендуют освобождение толстой кишки от каловых масс и поддерживающую терапию с применением полиэтиленгликоля (ПЭГ) с электролитами или без них. Однако практика показывает, что приемлемость, приверженность лечению и переносимость терапии ПЭГ проблематичны. Проведением консультаций родителей и детей по поводу ФЗ часто пренебрегают. Недавние исследования показывают, что коррекция поведения в сочетании с применением слабительных средств помогает избавиться от симптомов. Необходимы дальнейшие исследования, чтобы получить более определенные результаты, в том числе исследования на уровне оказания первичной медицинской помощи.
This review intends to update what is known and what is still a challenge in functional constipation (FC) in children regarding epidemiology, pathophysiology, diagnosis and management.
Although FC is a common childhood problem, its global burden remains unknown as data from parts of the world are missing. Another problem is that there is a large variation in prevalence due to differences in study methods and defining age groups. The pathophysiology of FC remains unclear until now, but is probably multifactorial. Withholding behaviour is likely to be the most important factor in toddlers and young children. Genetics may also play a role since many patients have positive family history, but mutations in genes associated with FC have not been found. Over the past years, different diagnostic criteria for FC in infants and children have been proposed. This year Rome IV criteria have been released. Compared to Rome III, it eliminates two diagnostic criteria in children under the age of 4 who still wear diapers. Except taking a good medical history and physical examination, other investigations such as abdominal radiography, trans abdominal recto-ultrasonography, colonic transit time, rectal biopsies and colon manometry are not routinely recommended. Regarding treatment, guidelines recommend disimpaction and maintenance therapy with Polyethylene glycol (PEG) with or without electrolytes. But experience learns that acceptability, adherence and tolerance to PEG are still a challenge. Counselling of child and parents about causes of FC is often neglected. Recent studies suggest behaviour therapy added to laxative therapy improves relieve of symptoms. Further homogenous studies, better-defined outcomes and studies conducted in primary care are needed.
