Short-term efficacy, safety and survival of laparoscopic radical resection for colorectal cancer patients with bowel obstruction

Objective:To investigate the short-term efficacy of laparoscopic radical resection for colorectal cancer with bowel obstruction and the effects of the surgery on inflammatory factors for improving the clinical treatment of the condition.

Methods:The data of colorectal cancer patients presenting bowel obstruction (n = 167) treated at our hospital from January 2019 to December 2020 were assessed. The patients were divided into a laparoscopic radical resection of colorectal cancer group (LRRCC, n = 90) and open surgery group (OP, n = 77). Before treatment and on the 1st, 3rd, 5th, 7th and 15th day after treatment, their serum levels of pain factors, neuropeptide Y, prostaglandin E2 and nerve growth factor were measured by a serum biochemistry analyzer, their levels of inflammatory factors including C-reactive protein, interleukin 6 (IL-6), IL-8 and tumor necrosis factor-α by ELISA, and their amount of CD3+, CD4+ and CD8+ T cell subsets were measure by flow cytometry. Anorectal motility was assessed before and 4 and 8 weeks after treatment. Survival rates were assessed using the Kaplan-Meier method.

Results:On the 1st, 3rd, 5th, 7th and 15th day after treatment, compared with the OP group, the LRRCC group had lower levels of serum pain factors, inflammatory factors and CD8+T lymphocytes, while their numbers of CD3+ and CD4+ T lymphocytes subsets were significantly increased. Further, the LRRCC group had fewer complications and significantly higher survival rates, demonstrating better efficacy than the OP group.

Conclusion:Laparoscopic radical resection was effective and achieved superior outcomes than open surgery in treating colorectal cancer patients with bowel obstruction.
