Anal Incontinence

About Anal Incontinence

Anal incontinence is the involuntary leakage of stool, gas or bowel contents at socially unacceptable times in anyone over four years of age. The condition can lead to social withdrawal, anxiety and a real loss of self-confidence. Many patients hesitate to seek help because of embarrassment, even though dependable surgical and rehabilitative options exist at specialist centres.

It is more common than reported, with an estimated prevalence of around two percent in the general population. People of all ages can be affected, although it is more frequent in older adults. Women are particularly vulnerable because of childbirth-related injuries, with around two-thirds of those affected over the age of thirty being female. Early evaluation makes a meaningful difference.

Common causes include traumatic childbirth with complete perineal tears, prior surgery for fissures, piles, fistulas or anal cancer, and direct injury from accidents or falls. Anal dilatation procedures and certain neurological conditions can also weaken the sphincter complex. Our team in Lucknow takes a careful history and examines the perineum gently to map the underlying problem.

Diagnosis combines a detailed history with digital rectal examination, which assesses resting tone and voluntary squeeze, and anorectal manometry, which records pressures at rest, on contraction and after defecation. When the sphincter is partially torn but margins are visible, a focused repair by gynaecology or general surgery may suffice. More extensive damage usually needs a reconstructive solution.

Plastic surgical input is requested when initial repairs have failed or when local tissue is poor. Dr. Agarwal, FRCS Edinburgh, performs gracilis sling reconstruction, using the gracilis muscle from the inner thigh as a passive sling around the anal canal, with reported success rates of 60 to 90 percent. Patients then follow a structured bowel-training programme to learn to contract and relax the new sling.

What to expect

• Detailed bowel and obstetric history
• Digital rectal examination and continence assessment
• Anorectal manometry to measure sphincter pressures
• Imaging such as endoanal ultrasound when indicated
• Counselling on direct repair versus gracilis sling
• Surgery under regional anaesthesia in lithotomy position
• Personalised post-operative bowel training programme

Recovery

• Hospital stay of three to five days
• Soft diet and stool softeners for two to three weeks
• Antibiotics and analgesics as prescribed
• Wound care for thigh and perineal incisions
• Pelvic floor and gracilis training exercises
• Gradual return to routine activity over four to six weeks
