What is the OTSC® Proctology?

The OTSC® is also available for proctology. The OTSC® clip application is an established method for the treatment of fistulas and anastomotic leaks in the digestive tract.

  • Rapid, minimallly invasive and sphincter sparing procedure1
  • Dynamic closure of anorectal fistulas and anastomotic leaks
  • High clinical effectiveness1,2

Advantages of the OTSC® Proctology

OTSC® Proctology is an innovative clipping system to be applied in proctological procedures. It is used for wall closure in the anorectum (e.g. fistulas) and offers the proctologist three unique advantages:

  • Easy transanal clip application by ergonomic one-hand operated instrument
  • No delayed loosening or rupture of sutures
  • High compression force at the lesion whilst protecting the tissue

The exceptional properties and therapeutic functions of the system are based on its special material and design: The superelastic Nitinol® is MRI- and biocompatible and, if needed, even suited to be applied as a long-term implant.

Application of the OTSC® Proctology

OTSC® Proctology is a sphincter-preserving surgical procedure for the effective closure of anorectal fistulas.

The use of the OTSC® Proctology system is intuitive, easy to use and similar to other techniques. All OTSC® Proctology products are disposable and designed for single patient use. The applicator is inserted transanally under direct vision. By pulling the trigger, the clip is released and pushed into the tissue from the applicator cap.

To facilitate the application, generally U-shaped sutures are placed at the target site. They can be pulled through the working channel by means of the pre-set thread retriever. After successful application of the clip, the sutures can be removed again. Alternatively, the OTSC® Proctology Anchor can be used as guidance and positioning aid.
