Abstract:

Objective

To investigate the effect of laparoscopic radical resection on gastrointestinal function, oxidative stress, and immune function in patients with colorectal cancer.

Methods

A total of 113 patients with colorectal cancer admitted to Xingtai People's Hospital from January 2018 to December 2020 were prospectively selected, and randomly divided into either a laparoscopic group (n=57) or a laparotomy group (n=56) using the random number table method. The laparoscopic group received laparoscopic radical resection, while the laparotomy group underwent open radical resection. Perioperative indicators (including intraoperative blood loss, operation time, and hospital stay), recovery of gastrointestinal function after surgery, and postoperative complications were recorded preoperative. Gastrointestinal hormones [gastrin and motilin], oxidative stress indicators [superoxide dismutase (SOD) and malondialdehyde (MDA)], and immune function indexes [immunoglobulin (Ig)A, IgG, and IgM] before surgery and at 24 h and 72 h after surgery were also recorded.

Results

Intraoperative blood loss was less, and operation time and hospital stay were shorter in the laparoscopic group than in the laparotomy group (P<0.05). The time to first exhaust and time to food intake were shorter in the laparoscopic group than in the laparotomy group (P<0.05). The postoperative complications in the laparoscopic group were less than those of the laparotomy group (P<0.05). The levels of gastrin and motilin at 24 h and 72 h after surgery were higher in the laparoscopic group than in the laparotomy group (P<0.05). SOD level was higher and MDA level was lower in the laparoscopic group than in the laparotomy group at 24 h and 72 h after surgery (P<0.05). The levels of IgA, IgG, and IgM in the laparoscopic group were higher than those in the laparotomy group at 24 h and 72 h after surgery (P<0.05).

Conclusion

Laparoscopic radical resection can promote the recovery of gastrointestinal function in patients with colorectal cancer, has fewer postoperative complications, and has little effect on patients' oxidative stress and immune function.

Key words: Laparoscopic radical resection, Colorectal cancer, Gastrointestinal function, Oxidative stress, Immune function
