INTODUCTION: In this study, we discovered that in CME for laparoscopic right hemi-colectomy starting at the ileocolic vessel and proceeds along the superior mesenteric artery (SMA) achieved a better oncologic outcome compared with the conventional ones proceeding along the superior mesenteric vein (SMV).
METHODS AND PROCEDURES: 46 patients admitted to a Shanghai minimally invasive surgical center were included from September 2015 to January 2017 and were randomly divided into two groups: study group(n=26) and conventional group (n=20). Operation time, blood loss during surgery, liquid intake time, postoperative hospital stay,postoperative complications within 30days after surgery,Specimen length, and number of lymph nodes harvested as well as the positive lymph node rate were observed and studied.
RESULTS: There was no statistical difference between the two groups with the exception of number of lymph node dissected and the positive lymph node rate for stage III colon cancer. The study group had more lymph node retrieved and also a higher positive rate compared with the conventional group. The mean number of lymph node retrieved of study group was 21.8 ± 2.47,while the conventional group was 19.9 ± 2.24.(P<0.05). And the positive lymph node rate for study group was 41.6%,the conventional group was 34.4%.
CONCLUSION: When performing the laparoscopic right hemi-colectomy, dissecting the lymph node along with the left side of SMA could be achievable and there were no differences of surgical outcomes compared with the conventional ways, while there was a higher number of lymph nodes dissected and positive rate probably leading to a better oncologic outcome.
