Understanding Anal Incontinence
Anal incontinence is characterized by the inability to voluntarily control the expulsion of stool, bowel contents, or fecal matter at socially acceptable times and locations in both men and women over the age of four years. This condition can lead to severe psychological and social distress, resulting in social isolation, diminished self-esteem, self-confidence, and even depression.
Prevalence of Anal Incontinence
Anal incontinence is considered a common but significantly underreported condition due to the embarrassment it causes. It has an estimated prevalence of 2.2% in the general population and can affect people of all ages. It is more common in older adults, although it should not be regarded as a normal part of aging. Females are more likely to develop anal incontinence, with 63% of those affected over the age of thirty being females.
Causes of Anal Incontinence
Anal incontinence has various causes, with trauma during childbirth and complete perineal tears being the most common. Additionally, surgeries in the perineal and anal regions can lead to this condition. For instance, it can occur after surgery for fissures, piles, fistula, cancer, and anal dilatation. Other factors, such as injury following trauma or accidents, can also contribute to the development of anal incontinence.
Diagnosis of Anal Incontinence
The diagnosis of anal incontinence involves several steps, including:
Thorough History: A detailed history is taken, including symptoms, bowel habits, dietary factors, medications, and other medical conditions.
Digital Rectal Examination: This examination assesses the resting pressure and voluntary contraction (maximum squeeze) of the anal sphincter. It can reveal significant sphincter dysfunction and the patient’s ability to exert voluntary control over the sphincter.
Anorectal Manometry: This test records the pressure exerted by the anal sphincters and puborectalis muscles at rest and during contraction, both before and after defecation.
Repair of Anal Sphincter
When the anal sphincter is found to be torn or injured, it can be repaired. If the margins of the cut muscle sphincter are visible and the damage is limited, the repair can be performed. This repair is typically done by gynecologists or general surgeons.
Role of Plastic Surgeons in Anal Incontinence Management
Plastic surgeons play a crucial role in the management of anal incontinence when initial surgical treatments have failed or when the damage is extensive, making local tissue repair challenging. The management of anal incontinence often involves a gracilis sling operation to encircle the anal sphincter. The gracilis muscle serves as an inert sling that offers passive resistance to the outflow of bowel contents. This procedure has a success rate ranging from 60% to 90%.
Surgery for Anal Incontinence at Kayakriti
The surgery for anal incontinence is usually performed under regional anesthesia, with the patient in the lithotomy position. Dr. Amit Agarwal harvests the gracilis muscle from the patient’s thigh. Three small longitudinal incisions are made on the inner aspect of the thigh. The muscle’s tendon is then introduced into a perianal tunnel at the sides and back of the anorectal region. The muscle is wrapped around the anal canal and reattached by stitches to the ischium (seat bone). A digital examination is performed after the sling is created to ensure that the sphincter functions effectively.
Recovery after Surgery
- Patients who undergo gracilis sling surgery for anal incontinence are typically placed on a soft diet for a few days.
- To prevent stretching of the muscle and tendon, patients are advised to avoid abduction (spreading outward) of the thigh.
Patients also undergo a period of training and exercises to learn to voluntarily contract and relax the gracilis muscle.
Bowel Training after Gracilis Sling Surgery
Bowel training involves understanding how the gracilis muscle contracts and relaxes. The muscle contracts when the thigh is abducted (spread outward), and it can be made to relax by assuming a squatting position, preventing abduction of the leg. On the other hand, the sphincter can be relaxed by squatting and avoiding abduction, while it can be contracted by standing and spreading the leg outward.

What are the common causes and factors contributing to the development of Vaginal Fistula?
Vaginal Fistulas can result from childbirth complications, surgical procedures, pelvic trauma, or underlying medical conditions. Factors such as prolonged labor or infections can contribute to their development.
What are the key signs and symptoms of Vaginal Fistula, and how does it impact an individual's physical and emotional well-being?
Symptoms may include urinary or fecal incontinence, vaginal discharge, and discomfort. Vaginal Fistulas can have a significant impact on an individual’s quality of life and emotional well-being.
How is Vaginal Fistula diagnosed, and what diagnostic methods are typically used to assess the condition's extent and impact on an individual's health?
Diagnosis often involves a physical examination, medical history, and diagnostic tests such as imaging studies or specialized tests to determine the type, size, and location of the Fistula.
What treatment options are available for individuals with Vaginal Fistula, and how does the involvement of plastic surgeons play a role in the treatment process?
Treatment options may include surgical repair of the Fistula. Plastic surgeons are often involved in these procedures, contributing their expertise in tissue reconstruction and restoration of normal anatomy.
