[Somatic symptoms often comorbid with benign anorectal disorders: a study of their significance]

Benign anorectal diseases represent a prevalent and intricate category of gastrointestinal disorders, encompassing conditions such as anal fissures, fistulas, hemorrhoids, incontinence, pain, and defecation disorders. These conditions include both anatomical abnormalities and functional disorders. Some patients continue to experience discomfort such as perianal discomfort, perineal heaviness, defecation difficulties, and abdominal bloating even after anatomical issues have been addressed, severely impairing social functioning. Generally, colorectal surgeons have paid little attention to somatic symptom disorder (SSD). This article introduced the manifestation of SSD in benign anorectal diseases from a psychosomatic perspective, advocating for the establishment of a biopsychosocial medical model in the diagnosis and treatment of these conditions to enhance patient rehabilitation outcomes. It is recommended that when benign anal diseases coexist with psychological disorders, SSD treatment should be used as a prerequisite. Surgical treatment should be considered only after the improvement of psychological disorders and SSD.
