Abstract:
Objective To analyze the effects of transrectal ectropion technique and anterior resection in the treatment of low rectal cancer.
Methods The clinical data of 93 patients with low rectal cancer from November 2017 to December 2020 were retrospectively analyzed. According to different surgical methods，47 patients treated with transrectal anal were included in the valgus group，and 46 patients treated with anterior resection were included in the anterior resection group. SPSS23.0 software was used for processing. Surgery indicators and Wexner score of anal incontinence were expressed as（
±
s），independent
t test was performed. The complications and tumor recurrence rate were expressed by percentages
χ2 test is used；the survival rate is tested by the
Log-Rank method.
P<0.05 was considered statistically significant.
Results In Eversion Group，the operation time，intraoperative blood loss were lower than that in anterior resection group，and the distance between distal margin and tumor inferior margin was greater than that of anterior resection group（P<0.05）. There was no significant difference in the complication rate between the valgus group and the pre-resection group（P>0.05）. 6 months after surgery，Wexner score in valgus group was lower than that in preresection group（P<0.05）. There were no significant differences in 1-year Wexner score，1-year and 3-year survival rate and tumor recurrence rate between 2 groups（P>0.05）.
Conclusion The transrectal anal ectropion technique is similar to anterior resection in the near，medium and long-term prognosis，but the former has a shorter operation time and less intraoperative blood loss，better to achieve the ideal margin of resection，control complications，and promote the recovery of anal function.
