Percutaneous endoscopic gastrostomy tube placement is an invaluable tool in clinical practice that has an important role in the palliative care of patients with gastrointestinal cancer. While there is no extensive data regarding the use of this procedure in patients with gastrointestinal malignancy, inferences can be made from the available information derived from studies of similar or mixed populations. Percutaneous endoscopic gastrostomy tubes can be used to provide enteral nutrition for terminal malignancies of the upper gastrointestinal tract as well as for decompression of malignant obstructions. The rates of successful placement for cancer patients with either of these indications are high, similar to those in mixed populations. There is no conclusive evidence that the procedure will help patients reach nutritional goals for those needing alimental supplementation. However, it is effective at relieving symptoms caused by malignant obstruction. A high American Society of Anesthesiologist physical status score and an advanced tumor stage have been shown to be independent predictors of poor outcomes following placement in cancer patients. This suggests the potential for similar outcomes in the palliative care of patients with advanced stage gastrointestinal cancer who may be in relatively poor physiologic condition. However, this potential should not preclude its use in patients with terminal gastrointestinal cancer considering the high rate of successful tube placement, the possible benefits and the ultimate goal of comfort in palliative care.
经皮内镜下胃造口管置入术是临床实践中一项非常重要的工具,在胃肠道癌患者的姑息治疗中发挥着重要作用。虽然目前尚无关于该手术在胃肠道恶性肿瘤患者中应用的广泛数据,但可从对相似或混合人群的研究中获取的现有信息进行推断。经皮内镜下胃造口管可用于为上消化道晚期恶性肿瘤患者提供肠内营养,以及缓解恶性梗阻。对于有上述任一适应证的癌症患者,置管成功率都很高,与混合人群相似。尚无确凿证据表明该手术能帮助需要营养补充的患者实现营养目标。然而,它在缓解恶性梗阻引起的症状方面是有效的。美国麻醉医师协会身体状况评分高和肿瘤分期较晚已被证明是癌症患者置管后预后不良的独立预测因素。这表明,对于生理状况相对较差的晚期胃肠道癌患者,在姑息治疗中可能会有相似的预后。然而,考虑到置管成功率高、可能的益处以及姑息治疗中舒适这一最终目标,这种可能性不应妨碍在晚期胃肠道癌患者中使用该方法。
