3D laparoscopic-assisted vs open gastrectomy for carcinoma in the remnant stomach: A retrospective cohort study

Figure 1 Flow chart of this study. CRS: Carcinoma in the remnant stomach; OGC: Open gastrectomy for CRS; 3DLAGC: 3D laparoscopic assisted gastrectomy for CRS.

Figure 2 Kaplan-Meier estimates of overall survival for open gastrectomy for carcinoma in the remnant stomach group and 3D laparoscopic assisted gastrectomy for carcinoma in the remnant stomach group. The 1-yr and 3-yr overall survival (OS) rates for the open gastrectomy group were 83.2% [95% confidence interval (CI): 72.4%-95.6%] and 73.3% (95%CI: 60.0%-89.5%) respectively. The 1-yr and 3-yr OS rates for the 3D laparoscopic assisted gastrectomy for carcinoma in the remnant stomach group were 87.3% (95%CI: 76.4%-99.8%) and 75.6% (95%CI: 59.0%-97.0%) respectively. However, there was no significant difference in 1-yr and 3-yr OS rates between the two groups, and the long-term survival results were comparable (P = 0.68). CRS: Carcinoma in the remnant stomach; OGC: Open gastrectomy for CRS; 3DLAGC: 3D laparoscopic assisted gastrectomy for CRS.
