Investigation of Defecation Function and Its Correlation with Quality of Life in Patients with Middle and Low Rectal Cancer after Anal Preservation
Objective To investigate the status quo of defecation function in patients with middle and low rectal cancer after anal preservation,and to analyze its correlation with quality of life(QOL).Methods From January 2022 to December 2023,total 50 patients who underwent anal preservation operation for middle and low rectal cancer in our hospital were selected as the study objects.All patients underwent temporary proctostomy first,and then underwent reversal surgery,and had been reversed for more than 1 month.The general data questionnaire was used to collect patient information,the Chinese version of the low anterior resection syndrome(LARS)rating scale was used to evaluate postoperative defecation func-tion,and the QOL assessment questionnaire(QLQ-C30)developed by the European Organization for Re-search and Treatment of Cancer(EORTC)was used to evaluate patients'QOL.Spearman correlation anal-ysis was used to analyze the correlation between defecation function and QOL.Results Among the 50 patients with middle and low rectal cancer after anal preservation,13 cases had no LARS,26 cases had mild LARS(52.0％),and 11 cases had severe LARS(22.0％).The total LARS score was(22.47±3.08)and the total QLQ-C30 score was(69.49±18.47).The total LARS score was negatively correlated with the total QLQ-C30 score(P＜0.05).Conclusion Most patients with middle and low rectal cancer after anal preservation have varying degrees of defecation dysfunction,which directly affects patients'QOL.Clinical attention should be paid to defecation after anal preservation for middle and low rectal cancer to improve patients'QOL.
