Summary

The Acticon artificial bowel sphincter offers long-term improved continence for intractable fecal incontinence. While infection remains a challenge, successful implantation leads to stable function and enhanced quality of life.

Area of Science:

  • Colorectal Surgery
  • Medical Device Technology
  • Gastroenterology

Background:

  • Fecal incontinence significantly impacts quality of life.
  • Intractable fecal incontinence presents a therapeutic challenge.
  • Artificial bowel sphincters are a treatment option for severe cases.

Purpose of the Study:

  • To evaluate the single-institution experience with the Acticon artificial bowel sphincter.
  • To assess the efficacy and outcomes of artificial bowel sphincter implantation for fecal incontinence.

Main Methods:

  • Retrospective and prospective review of 45 patients undergoing artificial bowel sphincter placement (1989-2001).
  • Group I (n=10) reviewed retrospectively; Group II (n=35) reviewed prospectively.
  • Outcomes assessed included device function, explantation rates, complications, and patient-reported scores.

Main Results:

  • In Group II, 35 of 37 attempted implantations were successful.
  • Explantation was required in 14 patients (34%) primarily due to infection (12 patients).
  • Fecal incontinence scores improved significantly (P < 0.001) and quality of life scores improved (P < 0.01) in patients with retained devices.

Conclusions:

  • Artificial bowel sphincter therapy can achieve long-term improved continence and quality of life.
  • Infection remains a significant challenge, impacting success rates.
  • Successfully implanted devices demonstrate stable function over many years.
