    This study evaluated an autosuturing device for closing urinary intestinal conduits. While effective in reducing operating time and contamination, staple-related complications like bleeding and stone formation warrant consideration.

    Area of Science:

    • Urology
    • Surgical Innovation
    • Gastrointestinal Surgery

    Background:

    • Urinary intestinal conduits are surgically created diversions for urine flow.
    • Conventional methods for conduit closure and bowel anastomosis can be time-consuming and increase contamination.
    • The development of automated suturing devices aims to improve surgical efficiency and outcomes.

    Purpose of the Study:

    • To assess the safety and efficacy of an autosuturing device in closing urinary intestinal conduits.
    • To compare the outcomes of using the autosuturing device with conventional techniques.
    • To identify potential complications associated with the use of this device.

    Main Methods:

    • The autosuturing device was used to close the base of 41 urinary intestinal conduits (12 colonic, 25 ileal, 4 jejunal).

  • Surgical techniques for device application were described.
  • Postoperative outcomes, including leaks, bleeding, obstruction, and stone formation, were monitored.

    • Main Results:

    • No urine or bowel leaks were observed in the 41 patients.
    • One patient experienced postoperative gastrointestinal bleeding and partial small-bowel obstruction, potentially linked to the stapled enteroanastomosis.
    • The device reduced operating time and peritoneal contamination, facilitating conduit manipulation.
    • Four patients formed stones (struvite and apatite) with embedded staples.

    Conclusions:

    • The autosuturing device is a viable alternative for proximal conduit closure and bowel anastomoses.
    • Careful consideration of potential staple-related complications, such as stone formation and obstruction, is necessary.
    • Further research may be warranted to optimize device use and mitigate risks.
