Area of Science:

  • Minimally Invasive Surgery
  • Gastrointestinal Surgery
  • Surgical Technology

Background:

  • Laparoscopic techniques are increasingly adopted for gastrointestinal procedures.
  • Intracorporeal anastomosis, performed entirely within the abdominal cavity, presents unique challenges.
  • The use of linear stapling devices is common, but their application in totally intracorporeal settings requires evaluation.

Purpose of the Study:

  • To evaluate the feasibility and safety of totally intracorporeal laparoscopic small bowel resection and anastomosis.
  • To assess the efficacy of a linear stapling device for this procedure in a porcine model.
  • To identify potential challenges and areas for improvement in advanced laparoscopic gastrointestinal surgery.

Main Methods:

  • Five domestic pigs underwent totally intracorporeal laparoscopic small bowel resection and anastomosis.

  • A 5-10 cm segment of jejunum was excised using a 30-mm linear stapler (Endo-GIA).
  • Bowel was anastomosed in a functional end-to-end fashion, and the enterotomy was closed with the stapler. Excised tissue was morcellated and removed via a retrieval sack.

    • Main Results:

    • All pigs recovered uneventfully with normal weight gain and oral feeding initiated on postoperative day one.
    • Post-sacrifice examination (4-10 weeks) revealed minimal adhesions and widely patent anastomoses.
    • No evidence of anastomotic leaks was observed, indicating successful tissue healing and sealing.

    Conclusions:

    • Totally intracorporeal laparoscopic small bowel resection and anastomosis using a linear stapling device is feasible and safe in a porcine model.
    • The technique shows potential for clinical application, though longer staplers may enhance ease of use.
    • Development of advanced laparoscopic suturing skills is crucial for the safe execution of complex procedures.
