Common anorectal illnesses frequently have overlapping symptoms. Numerous illnesses with both structural and functional impairment are among them (s). A diagnosis should only be made after analysing symptoms along with physiologic and structural abnormalities because symptoms alone are poor indicators of the underlying pathophysiology . The correct diagnosis of these conditions requires a thorough review of the patient's medical history, a thorough physical and digital rectal examination, and a systematic evaluation using high resolution and/or high definition three-dimensional (3D) anorectal manometry, 3D anal ultrasonography, magnetic resonance fecography, and neurophysiology tests. These physiological and imaging tests are essential for aiding in a correct diagnosis as well as for improving knowledge of the pathophysiology and functional anatomy. This results in better and more thorough care employing surgical, behavioural, and medicinal methods. In a similar vein, patients with significant rectal prolapse and dysfunction of the pelvic floor or those with complex enteroceles and prolapse of the pelvic organs may benefit from combined behavioural and surgical approaches, including open, laparoscopic, transabdominal or transanal, and/or robotic-assisted surgery. The pathophysiology, diagnosis, and treatment of a few prevalent anorectal disorders are updated in this article .
About 25% of people suffer from common anorectal diseases. Patients who experience symptoms including incontinence, rectal bleeding, anorectal pain, or rectal prolapse have either anatomical or functional problems of the anorectum or pelvic floor. Recent developments in diagnostic methods, in particular the introduction of high resolution and high definition anorectal manometry, ultrasound, and defecography have greatly improved the delineation of anatomical changes and phenotypes as well as a better understanding of the pathophysiology of these disorders, frequently leading to improved treatments.
Normal anatomy and physiology of pelvic floor
Understanding how to urinate normally and maintain continence is crucial. These critical functions rely on the anatomical stability and coordinated interaction of the pelvic floor muscles and nervous system. The pubococcygeus, ileococcygeus, and puborectalis are three different muscles that make up the deep pelvic muscles, often known as the levator ani. The pelvic organs are supported in large part by these muscles. The distal portions of the urethra, vagina, and rectum are drawn toward the pubic bones by the levator muscle's usual baseline activity . This process keeps the anorectal angle in place and builds a mechanical barrier to prevent faeces from flowing through and maintaining.
The internal and external anal sphincters as well as connective tissue make up the superficial layers of the pelvic floor. The evacuation of faeces from the rectal vault is largely under the control of these outer layers. The purposeful effort of bearing down, along with the contraction of the rectum and perineal muscles, raises the intra-abdominal pressure during typical defecation. The puborectalis and anal sphincters both relax at the same time, and the anorectal angle widens and the perineum descends. Stool evacuation is facilitated by these successive movements that help the rectum move the stool. Defecation issues can result from the pelvic floor muscles' lack of coordination, and faecal incontinence is brought on by the muscles' weakening.
General clinical evaluation: Digital rectal examination
The clinical evaluation must include a Digital Rectal Examination (DRE) and, if necessary, a vaginal examination. Skin excoriation or irritation from faecal soiling might be seen during an anorectal examination. The external anal sphincter will contract reflexively as you lightly stroke the perianal skin with a cotton swab or blunt needle in each of the four quadrants to assess perineal sensation and the anocutaneous reflex. A neuropathy should be suspected if this is missing. A stricture, spasm, discomfort, lump, blood, or stool may be discovered using DRE. If faeces are present, their consistency should be observed, and the patient should be questioned about their awareness of it. Stool in the rectum may not be felt, which may indicate rectal hyposensitivity . By having the subject squeeze, it is possible to evaluate the anal sphincter and puborectalis muscles' relaxed and squeezed tones. The patient should be instructed to push and bear down as if they were going to urinate. The examiner should notice perineal descent as well as relaxation of the puborectalis muscle and/or external anal sphincter during this manoeuvre. The amount of abdominal pressing force can be felt by placing a palm. When these regular mechanics are missing, dyssynergic defecation should be suspected. DRE has 87% specificity and a75% sensitivity for detecting dysynergia. To further assist in confirming or facilitating the diagnosis of rectocele and rectal prolapse, examinations during straining or bimanual rectal and vaginal examinations may be used. Despite the fact that DRE is a helpful therapeutic tool, there is a lack of understanding regarding how to conduct a thorough evaluation. 4 According to a poll of 256 medical students in their last year, 17% had never conducted a DRE and 48% were hesitant to provide an opinion based on their findings. Therefore, there is an urgent need for training on how to conduct .
Anorectal disorders present with a variety of symptoms and result from either structural or functional dysfunction. Clinical correlation is essential before labelling an abnormal finding as clinically significant. Together with a detailed history, a thorough physical and DRE and appropriate testing, in most patients the underlying cause and type of anorectal disorder can be correctly identified and treatment can be tailored.
