小肠CT联合单气囊小肠镜对黑斑息肉综合征的诊治价值

CHnical value of small bowel CT scan combined with single-balloon enteroscopy for Peutz-Jeghers syndrome

目的探讨小肠CT联合单气囊小肠镜诊治黑斑息肉综合征（PJS）胃肠道多发息肉的应用价值。方法对临床拟诊或诊断为PJS的5例患者行小肠cT检查，观察小肠息肉数目、大小、部位、相关肠道急性并发症等。根据小肠CT检查结果，采用单气囊小肠镜对小肠息肉进行相应镜下治疗，分析小肠息肉数目、大小、完成时间和并发症等。结果5例患者经小肠CT检查，发现大小不等小肠息肉，其中直径〉1．0cm的息肉共计68枚，最大的直径约4cm。共完成9例次小肠镜下治疗，平均完成时间120min，发现直径〉1．0cm的小肠息肉65枚，与小肠CT符合率为95．59％；共摘除息肉52枚，最大直径4cm，术后未发生并发症。结论小肠CT联合单气囊小肠镜诊治PJS胃肠道多发息肉安全、有效。

Objective To assess the value of small bowel computed tomography （CT） scan combined with single balloon enteroscopy （SBE） for the diagnosis and treatment of Peutz-Jeghers syndrome （PJS）. Methods CT scan was performed in cases that were clinically suspected or proved PJS for the number, size, location and relative acute complications of polyps in the small intestine. Single balloon enteroscopy was used to resect small intestinal polyps according to CT findings. The number of observed polyps in diagnosis, numbers of resected polyps, procedure duration and complications in endoscopic therapy were analysed. Results Polyps were found in the small intestine in all patients. There were 68 polyps whose diameter was 1-4 cm. Nine SBE procedures were completed in these patients. The mean procedure time was 120 rain. A total of 65 polyps were detected by SBE with 95. 59% concordance to CT results. A total of 52 polyps were resected under endoscopy, the largest diameter of which was 4 cm. No complications were observed after SBE. Conclusion Combination of small bowel CT scan and SBE is safe and effective for diagnosis and treatment of PJS patients, which is worth recommendation.
