Introduction:
This study aimed at assessing the long-term oncological outcomes of intracorporeal ileocolic anastomosis (ICA) for laparoscopic right hemicolectomy for colon cancer compared with extracorporeal anastomosis (ECA).
Material And Methods:
We performed a retrospective analysis of 149 consecutive patients who underwent laparoscopic right hemicolectomy for colon cancer between January 2006 and December 2012.
Results:
Eighty and 69 patients underwent intracorporeal and ECA, respectively. The two groups were demographically comparable. ICA exhibited a significantly shorter operative time (p < .0001), while local relapse and length of hospital stay did not significantly differ among the groups (p = .724 and .310, respectively). There was no significant difference in median number of retrieved lymph node. The overall survival and the disease-free survival at five years did not significantly differ among the groups.
Conclusions:
Intracorporeal ICA can reduce operative time and is associated with similar postoperative and long-term oncological outcomes compared to the ECA technique.
