Constipation is an important cause of technique failure and poor dialysis efficiency in Peritoneal Dialysis (PD) patients. A review of patient notes on our unit revealed 43% reported difficulties associated with constipation. A stool and laxative recording diary was sent to 126 PD patients. 46 patients reported using laxatives. All respondents using laxatives were invited to use a soluble dietary fibre supplement for 4 weeks, followed by dietary advice to see if they could achieve the same effect using high fibre foods. 23 patients entered the intervention stage of the study. 17 succeeded in replacing prescribed laxatives with the fibre supplement. 16 tried to increase their intake of high fibre foods, with 8 of these succeeding in improving their dietary intake of fibre; however only 2 were able to reduce their intake of fibre supplement. The results of the study suggest that a fibre supplement can be as effective as current laxative treatment in preventing constipation, as well as being the preferred choice of patients as many felt it improved bowel habits while not having the side effects of stimulant laxatives.
便秘是腹膜透析（PD）患者技术失败和透析效率低下的重要原因。对我们科室患者病历的回顾显示，43%的患者报告有便秘相关问题。我们向126名PD患者发放了大便和泻药记录日记。46名患者报告使用过泻药。所有使用泻药的受访者均被邀请使用可溶性膳食纤维补充剂4周，之后接受饮食建议，看看他们能否通过食用高纤维食物达到相同效果。23名患者进入研究的干预阶段。17名患者成功用纤维补充剂替代了处方泻药。16名患者试图增加高纤维食物的摄入量，其中8名患者成功提高了膳食纤维的饮食摄入量；然而，只有2名患者能够减少纤维补充剂的摄入量。研究结果表明，纤维补充剂在预防便秘方面与目前的泻药治疗效果相当，而且是患者的首选，因为许多人认为它改善了排便习惯，同时没有刺激性泻药的副作用。
