Abstract:

Objective

To investigate the impact and predictive value of sarcopenia on the occurrence of incisional hernia after colorectal cancer surgery.

Methods

A retrospective analysis was conducted on the clinical data of 150 patients who underwent radical surgery for colorectal cancer at Hangzhou First People's Hospital, Affiliated with the School of Medicine, Westlake University, from January 1, 2017, to December 31, 2019.Patients were divided into the incision hernia group (IH) and the non-incision hernia group (NIH) according to postoperative imaging findings.The preoperative muscle mass of patients was obtained by delineating the areas of different tissues at the level of the third lumbar vertebra (L3) in CT images.Cox regression was used to analyze the influence of sarcopenia and other clinical factors on postoperative incisional hernia in patients with colorectal cancer, and a nomogram model was established according to multivariate analysis to predict the risk of postoperative incisional hernia in patients with colorectal cancer.

Results

During the follow-up period, 26 patients (17.3%) developed incisional hernia after operation, and the skeletal muscle index (SMI) of L3 level in the IH group was(44.7±7.6) cm2/m2, which was significantly lower than that in NIH group (49.1±9.0) cm2/m2, the difference was statistically significant (t=-2.600, P=0.013).In multivariate analysis, it was found that sarcopenia(HR=3.709, P=0.004), rectal cancer (HR=3.982, P=0.002) and laparotomy (HR=2.404, P=0.043) were independent risk factors for the prognosis of postoperative incisional hernia in colorectal cancer, and a prediction model of postoperative incisional hernia in colorectal cancer was established accordingly.

Conclusion

Sarcopenia, rectal cancer and laparotomy are independent risk factors for postoperative incisional hernia in patients with colorectal cancer, which can be used to evaluate the incidence of postoperative incisional hernia.
