Abstract:
Objective
To explore the influence of visceral obesity on early complications after radical resection of rectal cancer.
Methods
The clinicopathological and preoperative imaging data of 234 patients who underwent laparoscopic radical resection for rectal cancer from October 2017 to October 2022 were retrospectively analyzed.According to visceral fat area (VFA), the patients were divided into visceral obesity group (n=108 cases) and non-visceral obesity group (n=126 cases).The clinicopathological features, intraoperative and postoperative conditions and early postoperative complications were compared between the two groups.SPSS25.0 statistical software was used to process the data, and the measurement data such as intraoperative and postoperative conditions were subjected to independent sample t test or Rank Sum test.The complication rate and other statistical data were chi-square test.Logistic regression model was used to analyze the risk factors of early complications after radical resection of rectal cancer.P<0.05 indicated that the difference was statistically significant.
Results
There were no significant differences in gender, age, tumor size, tumor distance from anal margin, T stage, TNM stage, differentiation degree and albumin between the two groups (P>0.05).BMI of visceral obesity group was higher than that of nonvisceral obesity group, with statistical significance (P<0.05).There was no significant difference in the first time of ventilation and the time of drainage tube removal between the two groups (P>0.05).Compared with non-visceral obesity, visceral obesity had longer operation time, more intraoperative blood loss and longer postoperative hospital stay (P< 0.05).Early complications were more likely to occur in patients with visceral obesity (P<0.05).Univariate analysis showed that VFA≥100 cm2, tumor distance from anal margin ≤5 cm,TNM stage Ⅲ/Ⅳ stage were risk factors for early postoperative complications (P<0.05).
Conclusion
Visceral obesity can increase the risk of intraoperative bleeding, prolong operation time and postoperative hospital stay.VFA≥100 cm2 is a risk factor for early postoperative complications of rectal cancer.
