Natural orifice translumenal endoscopic surgery (NOTES) offers potential benefits like reduced pain and infections. A hybrid small bowel resection using a rendezvous technique was successfully demonstrated in a cadaver model, highlighting the need for further instrument development.

Area of Science:

  • Minimally invasive surgery
  • Surgical innovation
  • Endoscopic procedures

Background:

  • Natural orifice translumenal endoscopic surgery (NOTES) is an emerging field.
  • NOTES aims to improve patient outcomes by reducing invasiveness.
  • Safety and efficacy must be established for widespread adoption.

Purpose of the Study:

  • To demonstrate a hybrid small bowel resection using the NOTES rendezvous technique.
  • To evaluate the feasibility of simultaneous transgastric and transcolonic approaches.
  • To showcase specialized instrumentation for NOTES procedures.

Main Methods:

  • A hybrid small bowel resection was performed in a cadaver model.
  • A rendezvous procedure utilized simultaneous transgastric and transcolonic access.

  • A powered stapling device and dual-channel endoscope were employed.

    • Main Results:

    • The NOTES hybrid small bowel resection was technically accomplished.
    • The procedure utilized specialized instrumentation and the rendezvous technique.
    • Laparoscopic ports were used in conjunction with endoscopic tools.

    Conclusions:

    • NOTES hybrid small bowel resection is achievable with current specialized instruments.
    • Technical limitations include enterotomy creation, tissue exposure, and closure.
    • Further instrument development is crucial for pure NOTES procedures.
