Researchers analyzed data from 1,152 patients with rectosigmoid cancer who underwent surgery. The study compared two specific surgical techniques: low inferior mesenteric artery ligation (LL) and high inferior mesenteric artery ligation (HL). The goal was to see if one method provided better long-term results for patients.
The findings showed that both surgical methods resulted in similar outcomes. There was no statistically significant difference in overall survival or disease-free survival over a 60-month period. Additionally, the rates of complications, such as anastomotic leaks, and the number of lymph nodes retrieved were comparable between the two groups.
Because the results were similar, this suggests that both surgical approaches are currently comparable for these patients. However, because this was a meta-analysis with a moderate level of certainty for survival data, these results should be discussed with a surgical team to determine the best approach for an individual case.
Common questions
Are there significant differences in survival between the two surgical methods?
The study found no statistically significant difference in 5-year overall survival or disease-free survival between the low and high artery ligation methods. The difference in overall survival was only 1.40 months, and the difference in disease-free survival was 0.71 months, meaning both methods performed similarly over the 60-month follow-up period.
Are there different risk levels for complications between these techniques?
The results showed that complications were comparable between the two methods. Specifically, the risk ratio for anastomotic leaks was 0.71 and the risk ratio for overall complications was 0.79. These figures suggest that both surgical techniques have similar safety profiles regarding common complications.
How does the surgical time or lymph node count differ between the methods?
The study found that the total number of lymph nodes retrieved and the total operating time were comparable between the two methods. The standardized mean difference for lymph nodes was 0.01 and for operating time was 0.08, indicating that the two techniques did not differ significantly in these areas.
