Intracorporeal Versus Extracorporeal Mechanical Anastomosis in Laparoscopic Right Colectomy


Verify with a prospective randomised trial if intracorporeal mechanical anastomosis in laparoscopic right colectomy reduces post-operative bowel canalisation time and length of stay in comparison with extracorporeal mechanical anastomosis.

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Treatment
    • Masking: None (Open Label)
  • Study Primary Completion Date: September 2013


  • Procedure: Laparoscopic right colectomy
    • Laparoscopic right colectomy with mechanical ileo-colon anastomosis L-L

  • Experimental: Intracorpopreal anastomosis
    • Intracorporeal mechanical anastomosis
  • Active Comparator: Extracorporeal anastomosis

Clinical Trial Outcome Measures

Primary Measures

  • Post-operative canalisation time and length of stay
    • Time Frame: Post-operative stay (about 7 days)
    • Comparison of post-operative bowel movement time (fist flastus and first dejection) and overall length of stay between the two study groups

Secondary Measures

  • Impact of post-operative ileum and complications. Valuation of global costs
    • Time Frame: 12 months
    • Comparison of post-operative short and long-term complications (in particular post-operative ileum) between the two study groups. Valuation of global costs differences.
