Laparoscopic Radical Resection versus Routine Surgery for Colorectal Cancer

For patients with colorectal cancer, minimally invasive surgical methods, particularly laparoscopic methods, are now the preferred course of therapy. This research is performed to investigate the effects of laparoscopic radical resection on patients with colorectal cancer. A total of 100 colorectal cancer patients treated in our hospital from January 2017 to January 2019 were enrolled. The subjects were divided into observation (n = 50) and control (n = 50) groups and treated with laparoscopic surgery and laparotomy, respectively. As well as postoperative complications and survival rates, the levels of inflammatory substances, stress response, immunological function, and perioperative markers were compared between the two groups. There was no significant difference in the postoperative exhaust time between the two groups (P > 0.05). Compared with the control group, the observation group showed longer operation time, faster recovery of intestinal function, shorter hospital stay, and less intraoperative bleeding amount (P < 0.05). The serum contents of hs-CRP, TNF-α, IL-6, norepinephrine, adrenaline, and cortisol at 1 d, 3 d, and 5 d after surgery were significantly higher than before in both groups (P < 0.05). Moreover, the serum contents of hs-CRP, TNF-α, IL-6, norepinephrine, adrenaline, and cortisol in the observation group were significantly lower than that in the control group (P < 0.05). At 10 days following surgery, immune index levels had dramatically increased in both groups, with noticeably higher immune index levels in the observation group than in the control group (P < 0.05). There were no appreciable differences in the two groups' 2-year survival rates (P > 0.05), but the complication rate was much greater in the control group (P < 0.05). To sum up, after laparoscopic surgery, patients had fewer complications, shorter hospital stay, lower inflammatory factor expression, less stress response, better immune function, less trauma, faster recovery, and improved quality of life.
