A multicenter trial was established to assess the use of a new disposable colostomy plug in achieving stomal continence during four weeks in patients with established colostomies. Forty-six of the 100 patients evaluated completed the trial, of whom 41 stated that they would wish to use the system regularly. Twenty-nine of the 41 continue to use the plug daily since the trial finished. The remainder withdrew mainly during the early stages of the trial because of leakage (ten patients), discomfort (11) or difficulties (12), all largely related to extrusion of the plug from the colostomy. There were no discernible features to predict in whom the plug was beneficial. Patients who irrigated the colostomy retained the plug longer (16.5 hours), on average, than those with natural evacuation (8.5 hours). However, even in the latter, the time increased with use of the system (week 1, 7.5 hours; week 4, 9.8 hours). Longer periods of retention of the plug appeared to be associated with improved stomal continence. Results from this trial confirm the potential of the Conseal Colostomy System incorporating a disposable colostomy plug to restore continence and improve life-style in more than one-third of patients with colostomies.
一项多中心试验开展，旨在评估一种新型一次性结肠造口术塞在已行结肠造口术患者中实现四周造口节制的应用情况。100名接受评估的患者中有46名完成了试验，其中41名表示希望定期使用该系统。自试验结束以来，41名患者中有29名继续每天使用该塞子。其余患者主要在试验早期因渗漏（10名患者）、不适（11名）或困难（12名）退出，所有这些情况大多与塞子从结肠造口挤出有关。没有可识别的特征来预测哪些患者使用该塞子有益。结肠造口冲洗患者塞子平均保留时间（16.5小时）比自然排便患者（8.5小时）更长。然而，即使在后者中，随着系统使用时间的增加，保留时间也会延长（第1周，7.5小时；第4周，9.8小时）。塞子保留时间更长似乎与造口节制改善有关。该试验结果证实了包含一次性结肠造口术塞的Conseal结肠造口系统在超过三分之一的结肠造口术患者中恢复节制和改善生活方式的潜力。
