Background Although hydrostatic reduction of intussusception with ultrasound (US) or fluoroscopy guidance is well known, it is not yet well established in many low-income and middle-income countries. The aim of the study is to report our results of hydrostatic reduction with intermittent radiography, which has the potential to be practiced in resource-limited settings. Methods We retrospectively analyzed our patients with intussusception from 2009 to 2019 (11 years). Hydrostatic reduction was performed using water-soluble contrast medium (iopamidol), and reduction was followed with intermittent X-rays taken after every 50 mL of diluted contrast injection. The procedure was not continuously monitored by US or fluoroscopy. Differences in outcome based on age and gender, and yearly trends of admission for intussusception, types of treatment and mortality were analyzed. Results Among 672 patients, the ratio of boys to girls was 2.46:1.0, and their ages ranged from 1 month to 15 years (median 8 months). Hydrostatic reduction was performed successfully in 351 (52.23%) patients; 308 (45.83%) patients underwent surgery; and 13 (1.93%) patients died before any intervention. There were significant differences in age between patients with successful hydrostatic reduction (median 7 months) and patients needing surgery (median 9 months) (p<0.001). The number of successful hydrostatic reductions increased during the 11 years of the study (R2=0.88). One patient (0.15%) died after hydrostatic reduction, and 10 (1.49%) died after surgery. Conclusion Hydrostatic reduction with intermittent radiography was performed successfully in more than half of the patients with acceptable complication rates.

间歇性放射照相静压复位套叠：低收入和中等收入国家透视或超声引导复位的替代方法

背景 尽管在超声 (US) 或透视引导下静压复位肠套叠已广为人知，但在许多低收入和中等收入国家尚未完全确立。该研究的目的是报告我们通过间歇射线照相减少静水压的结果，这有可能在资源有限的环境中实施。方法回顾性分析2009-2019年（11年）本院肠套叠患者。使用水溶性造影剂（碘帕醇）进行静水压还原，并在每 50 mL 稀释造影剂注射后进行间歇性 X 光检查。该过程未通过美国或荧光透视法进行连续监测。基于年龄和性别的结果差异，以及因肠套叠入院的年度趋势，分析了治疗类型和死亡率。结果672例患者中，男女比例为2.46:1.0，年龄1个月～15岁，中位8个月。351 例（52.23%）患者成功进行静水压复位；308 (45.83%) 名患者接受了手术；13 名 (1.93%) 患者在任何干预前死亡。成功进行静水压复位的患者（中位 7 个月）和需要手术的患者（中位 9 个月）之间的年龄存在显着差异 (p<0.001)。在 11 年的研究中，成功​​进行静水压减压的次数有所增加 (R2=0.88)。1 例（0.15%）患者在静水压复位后死亡，10 例（1.49%）在手术后死亡。
