OBJECTIVE: To compare the medial-to-lateral approach with the lateral-to-medial approach in laparoscopic right hemi-colectomy for right colon cancer. METHODS: A prospective randomized controlled trial was performed in the Fujian provincial tumor hospital between January 2007 and July 2009. Forty-eight cases with right colon cancer were randomly divided into two groups:medial-to-lateral laparoscopic right hemi-colectomy group(group M) and lateral-to-medial laparoscopic right hemi-colectomy group(group L). Primary outcome(operative time) and secondary outcomes (estimated blood loss, intra-operative complication, post-operative complication, number of lymph node retrieval, hospital stay) were compared between two groups. RESULTS: Operative time was(122.5+/-25.8) min in group M and (162.9+/-30.9) min in Group L (P=0.01). Estimated blood loss was(55.8+/-36.2) ml in group M and (104.6+/-58.2) ml in group L(P=0.01). There were no significant differences between the two groups in intra-operative complications(4.2% vs 8.3%, P=1.00), post-operative complications (8.3% vs 16.7%, P=0.66), number of lymph node retrieval (17.4+/-3.2 vs 17.8+/-3.4, P=0.67), and hospital stay[(7.8+/-2.2) d vs (8.0+/-3.6) d, P=0.81]. CONCLUSION: The medial-to-lateral approach reduces operative time and blood loss in laparoscopic right hemi-colectomy as compared with the lateral-to-medial approach.
