直腸癌低位前方切除患者の術後経過期間別の排便障害と自尊感情との関係について

The Relationship between Postoperative Bowel Dysfunction and Self-Esteem in the Postoperative Course Period after Low Anterior Resection for Rectal Cancer Patients

要旨

　本研究は，術後経過期間別に直腸癌低位前方切除（以下，LAR）患者の排便障害を評価し，排便障害と自尊感情との関係を検討することを目的とした．

　対象は，LAR後5年以内の外来通院患者60人で，方法は，質問紙による面接調査を行った．質問紙の内容は，基本属性，排便障害，自尊感情などであり，データの分析はMann-Whitney U検定とKruskal Wallisの検定，Pearsonの積率相関係数を用いた．

　その結果，LAR後の排便障害は，術後1年未満が1年以上2年未満と2年以上5年以下に比べ有意に高かった（p＜0.05）．しかし，1年以上2年未満よりも2年以上5年以下の排便障害が高い傾向があり，術後2年以降も排便障害を伴っていた．排便障害と自尊感情との関係では，術後2年以上5年以下において自尊感情が有意に低下していた（p＜0.05）．

　これらから，LAR患者は，術後2年以降も排便障害を伴い，術後2年以上5年以下においては排便障害が自尊感情に影響を及ぼす可能性が示された．

Abstract

　The purpose of this study is to evaluate postoperative bowel dysfunction in rectal cancer patients who had a low anterior resection (LAR) in the postoperative course period, and to examine the relationship between postoperative bowel dysfunction and self-esteem.

　This survey was conducted by interviewing with questionnaires 60 outpatients within a post- LAR 5-year period.

　The content of the questionnaire consisted of basic attribution, postoperative bowel dysfunction, self-esteem and analysis of the data was performed by the Mann-Whitney U Test and Kruskal- Wallis Test, and Pearson's product-moment correlation coefficient was used.

　The result shows that, for postoperative bowel dysfunction after LAR, the less than 1-year group suffered significantly more than the 2-to-5 year and 1-to-2 year group (p＜0.05). However, postoperative bowel dysfunction in the 2-to-5 year group tended to be higher than that of the 1-to-2 year group, which means that the patients suffered from postoperative bowel dysfunction 2 years after the operation. As for the relationship between self-esteem and postoperative bowel dysfunction, selfesteem was significantly lower in the 2-to-5 year group (p＜0.05).

　These findings suggest that LAR patients had postoperative bowel dysfunction 2 years after the operation and their self-esteem may also be affected by this in the 2-to-5 year group.
