Background and purpose: Anastomosis for laparoscopic colectomy is generally performed extracorporeally. Exteriorization of the bowel involves wide dissection and mobilization of the bowel. Hemorrhage during retraction for resection and anastomosis may occur. To solve these problems, intracorporeal anastomosis is performed, but its efficacy is not clear. We compared intracorporeal anastomosis (IA) with extracorporeal anastomosis (EA) for laparoscopic colectomy performed in our department, and assessed its efficacy.
Methods: We retrospectively analyzed 160 patients who underwent laparoscopic colectomy in our department.
Results: Sixty-nine patients underwent IA and 91 underwent EA. More patients in the IA group had relatively early-stage cancer, and there were differences in the extent or number of lymph node dissections. The IA group had significantly less blood loss. The two groups showed no differences in operative time or frequency of postoperative complications such as intraabdominal abscesses. There were no differences in location of tumor recurrence.
Conclusion: The results suggest that IA in laparoscopic colectomy is a minimally invasive and potentially useful technique.
