Abstract:

Objective

To investigate the relationship between the number of nail chambers in laparoscopic low anterior rectal resection(LAR)and postoperative low anterior rectal resection syndrome(LARS).

Methods

The clinical data of 186 patients with low rectal cancer treated in our hospital from June 2018 to June 2021 were retrospectively analyzed. According to whether LARS occurred after LAR,the patients were divided into LARS group(n=54 cases)and LARS group(n=132 cases)without LARS. The postoperative anal function of the patients was evaluated,and the data were statistically analyzed by SPSS 23.0 software. Through LASSO regression analysis and multiple Logistic regression analysis,the risk factors affecting the occurrence of postoperative LARS were analyzed,and the nomogram prediction model was established and evaluated. The correlation between the number of nail bins and the risk factors was analyzed by Pearson.

Results

Postoperative anal function was significantly improved. Six predictors were selected by LASSO regression analysis,and multivariate Logistic regression analysis was included. The results showed that BMI24 kg/m2,the distance from the lower tumor margin to the anal margin was <5 cm,neoadjuvant therapy was present,anastomotic leakage was present,intraoperative nail storage was used >2,and postoperative recovery time was 6 months. All were independent risk factors for LARS after surgery(P<0.05). There was a positive correlation between the number of nail chambers used and the probability of anastomotic leakage(P<0.05). The evaluation results of receiver operating characteristic(ROC)curve,calibration curve and clinical decision curve analysis(DCA)showed that the prediction model of this column graph had high differentiation,accuracy and effectiveness.

Conclusion

BMI24 kg/m2,distance from lower tumor margin to anal margin <5 cm,neoadjuvant therapy,anastomotic leakage,intraoperative nail bin use >2,and postoperative recovery time of 6 months were all independent risk factors for LARS. The nomogram model constructed in this study has high predictive value. The greater the number of nail chambers used during the operation,the greater the risk of postoperative anastomotic leakage. Laparoscopic LAR is effective in anal preservation for low rectal cancer.
