Abstract:
OBJECTIVETo investigate the safety, feasibility and long-term outcomes of laparoscopic complete mesocolic excision for the transverse colon cancer.
METHODSClinical data of 61 patients who underwent laparoscopic complete mesocolic excision for transverse colon cancer (transverse group) in our department from January 2011 to January 2014 were retrospectively analyzed, which were compared with those of 155 patients undergoing laparoscopic complete mesocolic excision for ascending colon cancer (ascending group) and 230 patients undergoing laparoscopic complete mesocolic excision for sigmoid colon cancer (sigmoid group). Differences in operative details, postoperative recovery, postoperative complications and long-term survival among 3 groups were evaluated.
RESULTSNo significant differences in the baseline information were found among 3 groups(all P>0.05). The average operative time was significantly longer in transverse group as compared to ascending group and sigmoid group [(192.1±58.7) min vs. (172.2±54.7) min and (169.1±53.6) min]( P<0.05), while the blood loss [(89.7±63.6) ml, (86.3±66.3) ml, (82.6±61.5) ml], conversion rate [3.3%(2/61), 2.6%(4/155), 2.2%(5/230)], number of harvested lymph node (13.0±4.7, 14.4±6.5, 13.4±5.6), time to flatus [(2.7±1.1) d, (2.6±1.1) d, (2.5±1.0) d], time to liquid diet [(3.0±1.7) d, (2.8±1.5) d, (2.7±1.4) d], incidence of postoperative complication(6.6%, 9.0%, 11.7%), and hospital stay [(11.6±5.8) d, (10.7±5.8) d, (10.6±5.7) d] among 3 groups were not significantly different (all P>0.05). A total of 436 patients received postoperative follow-up of median 36 (5 to 67) months. The overall 5-year survival rate was 73.1%, 73.7% and 74.8%, and the 5-year disease-free survival rate was 71.5%, 71.1% and 72.7% in transverse, ascending and sigmoid colon cancer groups respectively, whose differences were not significant among 3 groups (all P>0.05).
CONCLUSIONLaparoscopic complete mesocolic excision for transverse colon cancer is safe and feasible with slightly longer operation time, and has quite good long-term oncologic efficacy.
