Abstract:
Objective To explore and compare the different approaches of preserving left colonic artery in laparoscopic radical resection of middle and low rectal cancer.
Methods A total of 73 patients who received laparoscopic resection of middle and low left colon carcinoma from January 2016 to January 2020 were retrospectively reviewed. The left colic artery was preserved by traditional approach in 40 patients and bilateral approach in 33 patients. SPSS 23.0 statistical analysis software was used for comparison. Intraoperative postoperative indicators and other measurement data were expressed by（
±
s）and independent sample T test was used. The incidence of complications was compared by
χ2 test，
P<0.05 was considered statistically significant.
Results There were no significant differences in operation time，intraoperative blood loss，anastomotic time，total number of lymph node dissections，total number of lymph node dissections in the third group，postoperative VSA score，exsufflation time，recovery of bowel function，length of hospital stay recurrence rate of 2 years after surgery between the two groups（P>0.05）. the incidence of complications such as anastomotic leakage，anastomotic bleeding，intestinal blood obstruction，urinary retention and ureter injury in bilateral group was significantly lower than that in control group（P<0.05）.
Conclusion Compared with the traditional approach，bilateral approach laparoscopic radical resection of middle and low rectal cancer with preservation of left colon artery has similar curative effect，but can significantly reduce the incidence of postoperative complications.
