Anal Sphincter Repair -With Colostomy
Anal Sphincter Repair with Colostomy reconstructs a damaged anal sphincter causing faecal incontinence while creating a temporary colostomy to protect the repair during healing — restoring continence, dignity, and quality of life for patients living with this distressing condition.
Overview
Anal Sphincter Repair with Colostomy is a two-stage surgical approach to treating significant anal sphincter disruption causing debilitating faecal incontinence. The torn sphincter muscle ends are dissected from surrounding scar tissue and carefully overlapped and re-sutured to restore a functional sphincter ring, while a loop colostomy diverts faeces away from the repair during the healing phase. Once healing is confirmed at 8 to 12 weeks, a second procedure reverses the colostomy and restores normal bowel continuity — allowing the repaired sphincter to function normally and giving patients back the continence and confidence they deserve.
Types of Anal Sphincter Repair
Several surgical approaches exist depending on the mechanism of injury, the degree of sphincter disruption, and the patient's anatomy.
- Overlapping Sphincteroplasty (gold standard — overlapping the muscle ends for strongest closure)
- End-to-End Sphincteroplasty (direct approximation of the sphincter ends)
- Gracilis Muscle Transposition (using the inner thigh muscle to reconstruct a missing sphincter)
- Sacral Nerve Stimulation (neuromodulation for suitable cases of sphincter weakness)
- Artificial Bowel Sphincter Implantation (for patients in whom muscle repair is not feasible)
Risk Factors for Anal Sphincter Injury
Anal sphincter disruption occurs through traumatic and surgical mechanisms. Understanding these causes helps both patients and surgeons approach prevention and timely diagnosis.
- Obstetric injury during difficult vaginal childbirth — the most common cause in women
- Previous anorectal surgery including haemorrhoidectomy, fistula surgery, or sphincterotomy
- Traumatic injury to the perineum from accidents or direct trauma
- Inflammatory bowel disease causing progressive sphincter weakening
- Advancing age with progressive pelvic floor muscle weakness
- Radiation injury to the perineum from pelvic radiotherapy
Anal Sphincter Injury Symptoms
Faecal incontinence from anal sphincter injury is profoundly distressing but highly treatable. These symptoms should never be suffered in silence — expert help is available.
- Involuntary leakage of liquid or solid stool
- Inability to control flatus leading to embarrassing episodes
- Urgency with very little warning before losing bowel control
- Soiling of underwear with liquid stool or mucus
- Social isolation and anxiety about leaving the house
- Visible scar tissue or defect at the anal margin from previous injury
- Perineal pain or discomfort at the site of sphincter injury
- Depression and reduced quality of life from the psychological impact

Clinical Features
The technology, techniques and clinical approach behind our anal sphincter repair -with colostomy.
Gold standard overlapping sphincteroplasty technique for the strongest possible repair
Protective diverting colostomy ensures no faecal contamination of the repair during healing
Specialist stoma therapy nurse support from pre-operative counselling through to reversal
Anorectal manometry at 8 to 12 weeks confirms healing before colostomy reversal is planned
Permanent suture material used to create a durable, long-lasting sphincter reconstruction
Preparation Instructions
- Complete anorectal manometry, endoanal ultrasound, and MRI pelvis to map the sphincter defect precisely
- Provide all blood results including CBC, coagulation, and blood group
- Bowel preparation with oral laxatives and enemas is required the day before surgery
- Follow a low-residue diet for 2 to 3 days before surgery to minimise faecal contamination
- Stop anticoagulants 5 to 7 days before surgery under medical supervision
- Fast for 8 to 10 hours before the procedure
- Attend a pre-operative stoma therapy consultation to learn about colostomy management before surgery
- Arrange home support for 6 to 8 weeks — colostomy care education for patient and family is essential
The Procedure
Step-by-step guide to what you can expect during your anal sphincter repair -with colostomy procedure.
Colorectal Assessment and Functional Testing
Your colorectal surgeon reviews the results of anorectal manometry, endoanal ultrasound, and pudendal nerve testing to precisely map the location and extent of sphincter disruption, confirm surgical candidacy for repair, and plan the overlapping sphincteroplasty technique best suited to your anatomy.
Preparation and Stoma Team Education
Our specialist stoma therapist meets with you before surgery to explain the temporary colostomy — what it will look like, how to manage the bag, skin care, and what to expect during the weeks it is in place. This preparation dramatically reduces anxiety and ensures complete confidence in self-care after discharge.
General Anaesthesia and Prone Positioning
General anaesthesia is administered with you positioned prone (face-down) on a padded operating table to provide optimal surgical access to the perineum and anal sphincter complex. The perineal area is prepared in a careful sterile manner before surgery begins.
Sphincter Dissection and Overlap Repair
Your surgeon carefully identifies and dissects both ends of the torn sphincter from the surrounding scar tissue. The sphincter ends are then overlapped and secured with strong permanent sutures, creating a complete, reinforced sphincter ring of maximum circumference for optimal continence restoration.
Protective Loop Colostomy Formation
A small abdominal incision is made and a loop of sigmoid colon is brought to the abdominal surface to create the temporary diverting colostomy. This protective stoma diverts all faecal content away from the sphincter repair during the 8 to 12 weeks of healing, maximising the chance of a successful, durable repair.
Discharge with Full Self-Care Confidence
Before discharge, you perform full supervised colostomy bag changes with your stoma nurse until both you and the team are satisfied with your confidence and technique. Follow-up manometry at 8 to 12 weeks confirms adequate sphincter healing before planning your colostomy reversal procedure.
What to Expect
Anal Sphincter Repair with Colostomy is performed under general or spinal anaesthesia and takes approximately 2 to 2.5 hours. The sphincter is reconstructed and the temporary colostomy fashioned through the same abdominal incision. The stoma nurse will teach you exactly how to manage your colostomy safely and confidently before you leave hospital. Hospital stay is typically 4 to 7 days and colostomy reversal is planned at 8 to 12 weeks once healing is confirmed.
Recovery
Care for your colostomy exactly as taught by the stoma nurse — regular bag changes, skin protection, and monitoring for complications such as prolapse or stenosis. Attend all follow-up appointments including manometry at 8 to 12 weeks to confirm sphincter healing before colostomy reversal. Maintain a low-residue diet during the colostomy phase to manage stoma output and support the repair. Contact your colorectal team promptly for stoma problems, fever, wound pain, or bleeding.
