Endoscopic submucosal dissection for early gastric cancer and precancerous lesions enhances postoperative recovery and mitigates complication risks

Figure 1 Comparative analysis of surgical incision length, intraoperative blood loss, and operation duration between groups. A: Comparison of surgical incision length; B: Comparison of intraoperative blood loss; C: Comparison of operation duration. ^aP < 0.001, indicating a significant difference from the control group.

Figure 2 Postoperative recovery metrics between research and control groups. A: Time to first ambulation in research and control groups; B: Time to first flatus in research and control groups; C: Time to first oral intake in research and control groups; D: Length of hospital stay in research and control groups. ^aP < 0.01, highlighting significant differences from the control group.

Figure 3 Carcinoembryonic antigen, carbohydrate antigen 125, and carbohydrate antigen 19-9 levels pre- and post-surgery in research and control groups. A: Carcinoembryonic antigen levels in research and control groups; B: Carbohydrate antigen (CA)125 levels in research and control groups; C: CA19-9 levels in research and control groups. CEA: Carcinoembryonic antigen; CA: Carbohydrate antigen. ^aP < 0.01, ^bP < 0.001, reflecting significant changes from preoperative levels; ^cP < 0.05, denoting significant differences from the control group.
