A Retrospective Comparative Study of Small Bowel Capsule Endoscopy in Children and Adults

• 摘要：目的 对比儿童与成人小肠胶囊内镜检查特征及检出病变差异，为不同年龄患者检查策略的调整提供参考。方法 回顾性收集2011年8月至2021年2月于重庆医科大学附属第二医院行小肠胶囊内镜检查的881例患者临床资料，按年龄分为儿童组（<18岁）与成人组（≥18岁），分析两组检查指征及检出病变的构成情况，比较胃转运时间、小肠转运时间、全小肠检查完成率、病变检出率的差异。结果 儿童组的检查指征以疑似/确诊炎症性肠病（33.33%）、腹痛（30.36%）、疑似小肠出血（27.98%）为主，成人组以腹痛（39.69%）、疑似小肠出血（30.86%）为主。儿童组的中位胃转运时间长于成人，中位小肠转运时间短于成人组，差异均有统计学意义（P<0.05）。亚组分析提示胃转运时间、小肠转运时间在≤12岁儿童组与成人组间的差异有统计学意义（P<0.05）。儿童组与成人组在全小肠检查完成率、病变检出率上差异均无统计学意义（P>0.05），在检出病变上差异有统计学意义（P<0.05）。儿童组以溃疡（41.80%）为主要病变，成人组则以小肠炎症、糜烂（40.64%）多见。按检查指征分层分析提示，在相同检查指征下儿童与成人的检出病变差异均无统计学意义（P>0.05）。结论 小肠胶囊内镜在儿童与成人小肠病变检出中均具有良好的应用价值。对于12岁及以下儿童，应加强胶囊胃内转运情况的监测；检查指征能够提示潜在病变的类型，阅片时应结合具体临床指征关注重点病变。

  Abstract: Objective To compare the characteristics and detected lesions of small bowel capsule endoscopy (SBCE) between pediatric and adult populations, providing a reference for adjusting age-specific clinical examination strategies. Methods Clinical data were retrospectively collected from 881 patients who underwent SBCE at the Second Affiliated Hospital of Chongqing Medical University between August 2011 and February 2021. Patients were divided into the pediatric group (<18 years) and the adult group (≥18 years). The distribution of clinical indication and detected lesions was analyzed, and differences in gastric transit time (GTT), small bowel transit time (SBTT), completion examination rate (CER), and detection rate (DR) were compared between the two groups. Results The main clinical indication in the pediatric group were suspected/diagnosed inflammatory bowel disease (33.33%), abdominal pain (30.36%), and suspected small bowel bleeding (27.98%), whereas those in the adult group were abdominal pain (39.69%) and suspected small bowel bleeding (30.86%). The pediatric group had a longer GTT than the adult group, but a shorter SBTT than the adult group (P < 0.05). Subgroup analysis revealed that the differences in GTT and SBTT between children ≤ 12 years old and adults were both statistically significant (P < 0.05). No significant differences were observed in CER or DR between the two groups (P > 0.05). There was a significant difference in the detected lesions between the pediatric and adult groups (P < 0.05). Ulcers (41.80%) were the most common lesions in the pediatric group, while inflammation and erosion (40.64%) were the most common lesions in the adult group. Stratified analysis by clinical indication revealed that, under the same indications, there were no significant differences in the spectrum of detected lesions between the pediatric and adult groups (P > 0.05). Conclusion SBCE shows favorable clinical value in the detection of small bowel diseases in both pediatric and adult populations. Closer monitoring of gastric transit is recommended for children ≤ 12 years old. Since clinical indications can indicate potential lesion types, image interpretation should focus on key lesions in conjunction with specific clinical indications.
