Abstract:
Objective To investigate the effect of different medial boundaries of lymph node dissection on the follow-up of laparoscopic radical resection of right colonic cancer.
Methods The clinical data of 108 patients who underwent laparoscopic radical resection of right colonic cancer from May 2015 to May 2017 were studied retrospectively. According to the medial boundary of different lymph node dissections，they were divided into left group（left side of superior mesenteric artery）and right group（right side of superior mesenteric artery）. SPSS 24.0 statistical analysis software was used. Perioperative related indexes and SF-36 score were expressed by（
±
s），and independent sample
t test was performed；postoperative complications were expressed by percentage，and
χ2 test was performed；the cumulative survival rate was tested by
Log-Rank.
P<0.05 was considered statistically significant.
Results The number of lymph node dissections in the left group was more than that in the right group，and the operation time was longer than that in the right group（P<0.05）. The total physical health score（PCS）and mental health（MCS）in SF-36 scale after operation in both groups were higher than those before operation，and the left group was higher than that in the right group，the difference was statistically significant（P<0.05）. There were no significant differences in postoperative complications，distant metastasis and survival rate between 2 groups at 3 years follow-up（19.0% vs. 18.0%，5.1% vs. 4.0% and 96.6% vs. 94.0%，P>0.05）.
Conclusion Compared with right lymph node dissection of superior mesenteric artery，left lymph node dissection can improve the number of lymph node dissections in laparoscopic radical resection of right colonic cancer，improve the quality of life of patients，with good short-term results.
