Clinical research about bowel function and life quality in low rectal cancer anus preservation operation / 中国基层医药

ABSTRACT

Objective To investigate the condition of defecation function,psychological health and quality of life about patients who underwent low rectal cancer anus preservation operation.Methods We randomly selected 40 cases from patients who went to do rectal cancer anus preservation operation as observation group,who received e-valuation with bowel habit questionnaire (the result using Zhong-fa Xu anal function evaluation method which widely used for subjective evaluation),SF-36 scoring systems at 2 weeks before surgery,postoperative 3 months,6 months, 1 year,and the anorectal manometry postoperative 3 months,6 months,1 year.The normal controls were 40 healthy people without anus-rectal disease and disordered defecation,investigated and detected at the same time point.Results Compared with the control group,the ARP,MSP,RAIA,MTV of the observation group significantly decreased(P 0.05).Compared with the control group,in the preoperation,the results of anal function evaluation method and SF-36 scoring systems had no significant differences.Based on the Zhong-fa Xu anal function evaluation,we could draw the following conclusions:anal function was impaired obviously in postoperative 3 months (fine rate was 62.5%,χ2 =16.08,P 0.05),but the scores of PF and RF dimension were lower than those of the healthy con-trolspostoperative PF dimension[3 months(80.12 ±15.12),6 months(82.19 ±17.01),and 1 year(83.13 ± 17.12),compared with the control group,t =4.5,3.1,2.5 respectively],postoperative RP dimension [3 months(58.29 ±40.15),6 months(59.48 ±41.07),1 year(60.17 ±42.15),compared with the control group,t =4.1, 2.9,2.7 respectively];there were statistically significant differences (P <0.05).Conclusion For patients who underwent low rectal cancer anus preservation operation,postoperative anal function and life quality were affected,and is significant in a short period of time,part of the quality of life for long-term survival in patients decreased obviously, and it is necessary to assess sufficiently preoperation,do defecation function exercise or biological feedback therapy postoperation.
