Table 1_Comparison of the mixed approach and medial approach in laparoscopic right hemicolectomy for right colon cancer: a retrospective study.xlsx

PurposeThe study aimed to determine the 3-year disease-free survival (DFS) and overall survival (OS) outcomes of the mixed approach vs. the medial approach in laparoscopic right hemicolectomy.
MethodsThis retrospective study analyzed clinical data from 290 patients who underwent laparoscopic right hemicolectomies at our institution. Based on the surgical approach used, the patients were categorized into a medial approach group (n = 144) or a mixed approach group (n = 146). The primary endpoint was the 3-year DFS rate and the secondary endpoint was the 3-year OS. To minimize confounding, propensity score matching was performed based on six key variables.
ResultsNo significant difference was found in the baseline data between the two groups. Moreover, the results showed no significant difference between the medial approach and mixed approach groups in both DFS [HR = 1.799, 95% CI (0.9673, 3.347), p > 0.05] and OS [HR = 1.274, 95% CI (0.5521, 2.940), p > 0.05], regardless of tumor stage. Multivariate analyses demonstrated that tumor location and chemotherapy completion were independent prognostic factors for DFS.
ConclusionsAcross tumor stages, 3-year DFS and OS rates were similar between the two surgical approach groups. Thus, considering its safety and efficacy, the mixed approach may be a preferred alternative.
