The advent of double-balloon enteroscopy has enabled more accurate diagnosis and treatment of small bowel disorders. Single-balloon enteroscopy permits visualization of the entire small intestine less often than does double-balloon enteroscopy. However, the relative clinical advantages of the 2 methods remain controversial. This study therefore aimed to identify the indications for and therapeutic impact of performing single-balloon enteroscopy.
We retrospectively reviewed prospectively collected data from adults who underwent single-balloon enteroscopy from January 2007 through November 2011 and analyzed their baseline characteristics, endoscopic findings, pathological diagnoses, and clinical outcomes.
A total of 145 procedures were performed in 116 patients with a mean age of 58.1 ± 17.7 years (range, 18-89 years). The most common indications for performing single-balloon enteroscopy were overt gastrointestinal (GI) bleeding, chronic diarrhea, and occult GI bleeding, accounting for 57.9%, 12.4%, and 9.7% of the patients, respectively. The area of interest was achieved in 80.7% of the cases, with a 5.5% rate of technical failure. An overall positive finding was detected in 65.5% of the cases, of which 33.8% were ulcers and erosions; 8.3%, masses; and 3.4%, angiodysplasia. The diagnostic yields were 42.9%, 52.4%, 78.6%, 50.0%, and 25.0% for patients with overt GI bleeding, occult GI bleeding, abdominal pain, chronic diarrhea, and abnormal imaging results, respectively. Therapeutic procedures were performed in 11% of patients with GI bleeding and achieved a therapeutic yield of 14.6% with a minor complication rate of 11.7%.
Single-balloon enteroscopy was effective for the diagnosis and treatment of small bowel disorders, especially in patients who presented with abdominal pain, GI bleeding, or focal abnormalities on imaging scans.
双气囊小肠镜的出现使小肠疾病的诊断和治疗更加准确。与双气囊小肠镜相比，单气囊小肠镜检查通常无法观察整个小肠。然而，这两种方法的相对临床优势仍存在争议。因此，本研究旨在确定单气囊小肠镜的适应证和治疗效果。
我们回顾性分析了 2007 年 1 月至 2011 年 11 月期间行单气囊小肠镜检查的成年患者的前瞻性数据，分析了他们的基线特征、内镜表现、病理诊断和临床结果。
116 例患者共进行了 145 例次单气囊小肠镜检查，平均年龄为 58.1±17.7 岁（18-89 岁）。行单气囊小肠镜检查的最常见适应证为显性胃肠道（GI）出血、慢性腹泻和隐性 GI 出血，分别占患者的 57.9%、12.4%和 9.7%。80.7%的病例达到了目标部位，技术失败率为 5.5%。总体阳性发现率为 65.5%，其中 33.8%为溃疡和糜烂；8.3%为肿块；3.4%为血管发育不良。显性 GI 出血、隐性 GI 出血、腹痛、慢性腹泻和异常影像学结果患者的诊断率分别为 42.9%、52.4%、78.6%、50.0%和 25.0%。对 GI 出血患者进行了治疗性操作，治疗率为 11%，并发症发生率为 11.7%。
单气囊小肠镜对小肠疾病的诊断和治疗有效，特别是对有腹痛、GI 出血或影像学扫描有局灶性异常的患者。
