Chronic constipation: modern view on the problem. A review

Abstract

Chronic constipation is a frequently diagnosed heterogeneous pathology that significantly impairs the quality of life in all population groups and its frequency increases with age. It commonly affects up to 10 — 15  % of the population. There are numerous classifications of constipation due to a great number of disorders that cause it. The types of constipation are identified based on the etiology or mechanism of its development. Different criteria are used to specify the categorization of constipation, but it is still difficult to find one general classification including all types of constipation. The Rome IV criteria categorize disorders of chronic constipation into four subgroups. The treatment depends on the subtype. The significant increase of constipation cases is observed nowadays. This disorder is facilitated by a sedentary lifestyle, insufficient amount of fiber and fluid in the diet, a wide range of diseases that directly lead to the development of chronic constipation, congenital and acquired pathologies, abnormal intake of laxatives and opioids or a combination of these factors. Despite numerous publications on slow transit constipation, the latter is still the subject of research for many specialists. A lot of recent scientific works have been dedicated to the immunohistochemical studies of interstitial pacemaker cells. The numbers of markers they express were found. Consequently, the investigations of modern scientists are aimed to develop and implement new laboratory methods for determining the indications for surgical treatment depending on a diagnosed disorder of the intestinal neurophysiology. These methods will ensure a differentiated selection of patients for surgical treatment. The step approach to the diagnosis of chronic constipation allows choosing an adequate treatment method in order to improve symptoms, the quality of life, and patient satisfaction. The literature review indicates that surgery still remains the most radical treatment method for patients with slow transit constipation.
