目的 提高对幼年性息肉致小肠套叠的诊治水平。方法 按检索策略，检索PubMed、中国生物医学文献数据库（CBM）、中文科技期刊全文数据库（CSJD）、中国期刊全文数据库（CJFD）及CNKI数字图书馆的相关文献，并结合笔者所在医院于2011年收治的1例幼年性息肉致小肠套叠病例资料，对该病进行一系统的描述。结果 共检出相关文献65篇，按纳入及排除标准，最后纳入6篇文献。共7例患者，临床表现为腹痛、呕吐5例，便血2例，贫血3例；经超声检查诊断4例；全组均行小肠切除肠吻合术，其中1例为腹腔镜辅助手术；有1例患者共实施了3次手术，最后死于恶液质，其余患者恢复较好。结论 幼年性息肉致小肠套叠为临床罕见疾病，超声检查仍为首选诊断方法；提高医师对该病的认识，术中彻底探查肠道，必要时术中行快速冰冻切片病理学检查，有望减少息肉遗留，改善患者的预后。
目的总结降低胰十二指肠切除术后胰空肠吻合口漏发病率的经验体会。 方法切除胰头后，将胰腺残端游离2.5～3.0 cm，利用红色石蕊试纸遇碱性胰液变蓝的特性，帮助寻找胰腺断面被横断的小导管，丝线贯穿缝扎。将空肠袢断端2.0～2.5 cm浆肌层剥除后施行套叠式胰空肠端端吻合，距浆肌层游离缘1.0～1.5 cm 处空肠上下壁各缝1针固定，最后用纤维蛋白胶封闭吻合口。结果47例患者中无一例发生胰空肠吻合口漏。结论该法操作较简便，适用于胰腺残端各种情况的处理。
目的 总结成人大肠套叠治疗经验。方法 回顾性分析我院1969～1998年收治的83例成人大肠套叠患者的临床资料。结果 经钡灌肠复位6例，手术治疗77例。肿瘤性大肠套叠60.2%，其中恶性肿瘤性套叠占64.0%。恶性肿瘤套叠手术切除5年生存率43.8%。结论 对成人大肠套叠治疗首选手术切除，慎用手术复位，不主张钡灌肠复位。
ObjectiveTo study the clinical significance of color Doppler ultrasound in the diagnosis of intussusception in children. MethodsWe retrospectively analyzed the color Doppler ultrasound results of 150 children with intussusception confirmed by X-ray air enema and surgery between January 2010 and December 2012. ResultsThe 150 children included 18 cases of necrosis, and 132 cases of simple edema; there were 122 cases of ileocecal intussusception, 22 cases of colon, and 6 of small intestine. Surgical treatment was performed for 30 cases, and 120 cases were treated with X-ray air enema reduction. Ultrasonic diagnosis was correct in 144 cases with an accurate rate of 96.0%; 6 cases were misdiagnosed, and misdiagnosis rate was 4.0%. ConclusionUltrasound in the diagnosis of children intussusception is simple, rapid, non-invasive, with no side-effects of radiation exposure, and selection of this method clinically has a very important significance.
目的 比较电脑遥控灌肠整复仪与简易空气灌肠器对小儿肠套叠的整复效果，探讨更有效安全的空气灌肠设备。 方法 2002年11月－2011年11月对确诊的425例小儿肠套叠应用空气灌肠整复，其中198例采用简易空气灌肠器整复，227例用电脑遥控灌肠整复仪进行空气灌肠整复，并对不同病程时间、套叠部位与两种空气灌肠设备整复结果进行回顾性分析。 结果 198例患儿采用简易空气灌肠器整复成功率为71.2%，227例患儿采用电脑遥控灌肠整复仪的方式整复成功率为83.3%，后者成功率明显高于前者（P＜0.005），尤其是病程时间在24 h内，套叠部位位于升结肠或横结肠的后者整复成功率更高（P＜0.05）。 结论 电脑遥控灌肠整复仪比简易空气灌肠器更有效、安全。脉冲式空气灌肠能减轻套叠部位的痉挛与水肿，提高肠套叠的整复成功率。
To assist grassroots sonographers in accurately and rapidly detecting intussusception lesions from children's abdominal ultrasound images, this paper proposes an improved YOLOv8n children's intussusception detection algorithm, called EMC-YOLOv8n. Firstly, the EfficientViT network with a cascaded group attention module was used as the backbone network to enhance the speed of target detection. Secondly, the improved C2fMBC module was used to replace the C2f module in the neck network to reduce network complexity, and the coordinate attention (CA) module was introduced after each C2fMBC module to enhance attention to positional information. Finally, experiments were conducted on the self-built dataset of intussusception in children. The results showed that the recall rate, average detection accuracy (mAP@0.5) and precision of the EMC-YOLOv8n algorithm improved by 3.9%, 2.1% and 0.9%, respectively, compared to the baseline algorithm. Despite slightly increased network parameters and computational load, significant improvements in detection accuracy enable efficient completion of detection tasks, demonstrating substantial economic and social value.
