客观的。本研究的目的是确定大量患者群体中成人博赫达莱克疝的患病率和特征。材料和方法。我们回顾性地回顾了 1998 年在我们医院获得的所有腹部 CT 扫描，我们研究中的患者是通过在数据库中搜索“Bochdalek”、“疝气”和“膈肌”等关键词来识别的。确定的个体患者研究以软拷贝形式进行审查。我们记录了膈疝发生的位置和身体侧面以及囊的内容物。我们还对研究中的每位患者进行了图表审查，记录了患者的性别、年龄和症状。结果。 22 名患者（17 名女性，5 名男性）被诊断为意外 Bochdalek 疝气，根据我们审查的 13,138 份腹部 CT 报告，其发病率为 0.17%。患者的平均年龄为66.6岁。没有患者出现症状。 68% 的疝气位于身体右侧，18% 位于左侧，14% 位于双侧。 73% 的患者仅含有脂肪或大网膜，而 27% 的患者有实体或肠道器官受累，包括脾、小肠或大肠。 结论，Bochdalek 疝并不罕见，并且含有肠道的 Bochdalek 疝的发病率高于以前报道的。这一发生率可能代表保守估计，因为一些博赫达莱克疝气可能被忽视或未报告。
OBJECTIVE. The purpose of this study was to determine the prevalence and characteristics of adult Bochdalek's hernia in a large patient population.MATERIALS AND METHODS. We retrospectively reviewed all abdominal CT scans obtained at our hospital in 1998, Patients in our study were identified through a keyword search of our database for "Bochdalek," "hernia," and "diaphragm." The individual patient studies identified were reviewed in a soft-copy format. We noted the location and side of the body on which the diaphragmatic hernia arose and the contents of the sac. We also performed a chart review for each patient included in the study, noting the patient's sex, age, and symptoms.RESULTS. Incidental Bochdalek's hernia was diagnosed in 22 patients (17 women, five men), which represents an incidence of 0.17% based on 13,138 abdominal CT reports we reviewed. The mean age of the patients was 66.6 years. None of the patients were symptomatic. Sixty-eight percent of the hernias were on the right side of the body, 18% were on the left side, and 14% were bilateral. Seventy-three percent contained only fat or omentum, whereas 27% had solid or enteric organ involvement including the spleen, small intestine, or large intestine.CONCLUSION, Bochdalek's hernia is not rare, and the incidence of Bochdalek's hernias that contain enteric tract is higher than previously reported. This incidence likely represents a conservative estimate because some Bochdalek's hernias may have been overlooked or unreported.
