Emergent surgical management of malignant large bowel obstruction (LBO) carries a high rate of morbidity and mortality. Self-expanding metal stents have emerged as an alternative for palliation of malignant LBO. However, there are few long-term studies documenting the effect of surgical palliation or colonic stents on symptoms or quality of life (QoL).
Between 2003 and 2006, patients with unresectable-for-cure malignancies presenting with LBO were enrolled in this prospective study. Patients elected to undergo stent placement or surgical palliation. Patients completed a symptom questionnaire and a QoL instrument (Functional Assessment of Cancer Therapy-Colorectal [FACT-C]) at weeks 1, 2, 4, 8, 12, and 24 after palliation. Symptoms were assessed using the Colon Obstruction Score, a novel instrument comprising nausea, vomiting, pain, distension, and bowel movement frequency scores.
Thirty patients had successful stent placement; 14 underwent surgical diversion. Colon Obstruction Scores immediately improved after both stent placement and surgery (p < 0.05 for all time points). Composite FACT-C scores progressively improved after stent placement (p = NS), with the colon symptoms subscale improving after 1 month (p < 0.05). FACT-C scores declined initially after surgery and then returned to baseline, with modest improvements seen in the Colon Symptoms subscale (p = NS).
Both stent placement and surgical diversion provide durable improvement in symptoms from LBO, as readily assessed by the Colon Obstruction Score. QoL is difficult to assess in terminal cancer patients, but colon stent placement is associated with improved overall QoL and QoL related to gastrointestinal symptoms.
紧急外科手术处理恶性大肠梗阻(LBO)的发病率和死亡率很高。自膨式金属支架已成为恶性 LBO 姑息治疗的替代方法。然而,很少有长期研究记录手术姑息治疗或结肠支架对症状或生活质量(QoL)的影响。
在 2003 年至 2006 年间,患有不可切除的恶性肿瘤并伴有 LBO 的患者被纳入这项前瞻性研究。患者选择接受支架放置或手术姑息治疗。患者在姑息治疗后 1、2、4、8、12 和 24 周时完成症状问卷和生活质量工具(功能性评估癌症治疗-结直肠癌[FACT-C])。症状使用新的结肠梗阻评分来评估,该评分由恶心、呕吐、疼痛、腹胀和排便频率得分组成。
30 名患者成功进行了支架放置;14 名患者接受了手术分流。支架放置和手术后,结肠梗阻评分立即改善(所有时间点的 p < 0.05)。支架放置后,复合 FACT-C 评分逐渐改善(p = NS),1 个月后结肠症状子量表改善(p < 0.05)。手术后 FACT-C 评分最初下降,然后恢复基线,结肠症状子量表略有改善(p = NS)。
支架放置和手术分流都能持久改善 LBO 的症状,这可以通过结肠梗阻评分很容易地评估。在终末期癌症患者中,生活质量很难评估,但结肠支架放置与总体生活质量的改善以及与胃肠道症状相关的生活质量改善有关。
