Sphincter repair for fecal incontinence

Area of Science:

• Colorectal Surgery
• Pelvic Floor Disorders
• Surgical Outcomes Research

Background:

• Fecal incontinence is a debilitating condition often resulting from sphincter damage.
• Previous surgical interventions and childbirth are common etiologies for anal sphincter dysfunction.
• Management of anal incontinence requires understanding patient history and surgical options.

Purpose of the Study:

• To evaluate the long-term outcomes of anal sphincter repair surgery.
• To identify factors influencing the success of sphincter repair.
• To assess the impact of secondary operations on anal continence.

Main Methods:

• Retrospective review of 27 patients undergoing sphincter repair by a single surgeon over ten years.
• Analysis of patient history, including prior surgeries, childbirth, and trauma.
• Assessment of pre- and post-operative continence status and anal pressures.

Main Results:

• Initial complete continence was achieved in 7 of 27 patients; 13 showed improvement, and 7 had poor results.
• Four of the 7 patients with poor initial outcomes achieved complete continence after secondary operations.
• Preoperative maximum squeeze pressure was significantly higher in patients who ultimately achieved complete continence.

Conclusions:

• Sphincter repair can improve anal continence, with secondary procedures offering further benefit.
• Severe obstetric trauma is associated with suboptimal outcomes.
• Preoperative anal manometry, specifically maximum squeeze pressure, may predict surgical success.
