Intracorporeal versus extracorporeal anastomosis in laparoscopic right hemicolectomy A retrospective study and review of literature.

Introduction: Several studies have suggested that intracorporeal anastomosis (IC) has advantages over extracorporeal anastomosis (EC) in laparoscopic right colectomy. Scientific evidence is lacking. The aim is to define the possible benefits of intracorporeal anastomosis compared with extracorporeal anastomosis in elective surgery.
Methods: A single-centre retrospective study was performed. The primary endpoint was duration of hospital stay. Secondary outcomes included operative time, bowel recovery, conversion to open surgery and postoperative complications.
Results: In the IC group mean hospital stay was 7,100 days, mean age was 70,5 years, mean operating time was 233 minutes and mean time to restoration of digestive function was 3,950 days. In the EC group mean hospital stay was 9,455 days, mean age was 72,55 years, mean operating time was 183 minutes, mean time to restoration of digestive function was 5,364 days.
Conclusion: This study shows many clinical outcomes advantages for the intracorporeal anastomosis technique in laparoscopic right colectomy. IA was associated with earlier bowel recovery, decreased hospital stay and fewer complications; operative time was shorter in EA KEY WORDS: Anastomosis, Colon cancer, Laparoscopy, Hemicolectomy, Retrospective.
