Comparison of NOSE and Conventional Methods in Laparoscopic Right Colon Surgery


Laparoscopic right hemicolectomy (LRH) is an accepted surgical procedure for several right sided colonic pathologies. Recently the advantages of the intracorporeal ileotransversostomy over the extracorporeal anastomosis is appearing in the literature. Additionally, specimen extraction through the natural orifices is an emerging method when combined with the totally laparoscopic procedures. Our observations on natural orifice surgery was promising . In our daily surgical practice, investigators prefer the intracorporeal anastomosis and this study was conducted to compare the specimen extraction sites after LRH. Here investigators aimed to compare the results of conventional and natural orifice specimen extractions (NOSE) after totally LRHs.

Detailed Description

compare the patient-selected NOSE method and conventional method in laparoscopic right colon cancer surgery


  • Procedure: natural orifice
    • laparoscopic right colon surgery and patients who are removed from the natural orifice and conventional will gather

Arms, Groups and Cohorts

  • Experimental: natural orifice
    • Patients who underwent laparoscopic surgery and removed the specimen from the natural orifice will be gathered. demographic data and perioperative results will be compiled
  • No Intervention: conventional
