The Laparoscopic Right-lower Quadrant Approach for the Treatment of Right-sided Colon Cancer Offers Advantages Such as Shorter Surgical Time and Less Blood Loss.

Objective: This study aims to compare the therapeutic efficacy of laparoscopic right-lower quadrant and midline approaches for the treatment of right-sided colon cancer and evaluate the analgesic effect of parecoxib sodium.

Methods: Sixty patients with right-sided colon cancer admitted to Hospital of Lin 'an District between January 2019 and November 2022 were selected. They were divided into the study group A (n=30) with a right-lower quadrant approach and the study group B (n=30) with a midline approach. All patients received parecoxib sodium. Surgical time, blood loss, postoperative complications, and other relevant indicators were recorded and compared between the two groups. Additionally, a control group of 60 right-sided colon cancer patients who underwent conventional non-exclusive analgesic laparoscopic surgery during the same period was included to compare the analgesic effects between the study and control groups.

Results: The surgical time (RR = 0.608, 95%CI 0.51, 1.53, P = .042), blood loss (RR = 0.798, 95%CI 0.52, 1.02, P < .001), time for bowel function recovery (RR = 0.808, 95%CI 0.50, 1.77, P = .007), and length of hospital stay (RR = 0.766, 95%CI 0.56, 1.72, P =.052) were significantly lower in group A than in group B, while the number of lymph node dissections was higher in group A (RR = 0.803, 95%CI 0.62, 1.52, P = .047). The postoperative levels of tumor-specific growth factor (TSGF) (RR = 0.710, 95%CI 0.50, 1.55, P < .001) and carcinoembryonic antigen (CEA) (RR = 0.803, 95%CI 0.62, 1.52, P < .001) were significantly decreased in both groups A and B, with no significant difference between the groups (P > .05). The incidence of complications in group A was significantly lower than in group B (RR = 0.167, 95%CI 0.17, 0.63, P = .044). The VAS scores of the study group at 2/4/6/8 hours postoperatively were significantly lower than those of the control group (RR = 0.702, 95%CI 0.52, 1.62, P < .001). The SF-36 scores of the study group were significantly higher than those of the control group (RR = 0.753, 95%CI 0.56, 1.82, P < .001).

Conclusions: The Laparoscopic right-lower quadrant approach for the treatment of right-sided colon cancer offers advantages such as shorter surgical time and less blood loss. It demonstrates significant clinical efficacy and reduces the incidence of postoperative complications. Parecoxib sodium enhances postoperative analgesic effect, effectively alleviating patient pain, promoting recovery, and improving quality of life. It is worth promoting in clinical practice.
