Background: Bochdalek hernia in an adult is very rare and often needs an immediate surgical repair for the herniation. Although its etiology and surgical techniques have frequently been reported, perioperative complications, especially cardiopulmonary problems, remain unknown. We reported two adults with Bochdalek hernia and reviewed the published literatures with a focus on these issues. Case presentation: We experienced two adult cases of Bochdalek hernia with gastrointestinal strangulation. One case had massive herniation of the stomach, colon, spleen, and pancreas in the left chest, causing repeated vomiting. The other had a right-side hernia with strangulation of the colon. We successfully performed emergency repairs of these diaphragmatic hernias without any postoperative complications. Conclusions: Our literature review revealed that life-threatening cardiopulmonary complications, such as empyema or cardiac arrest caused by the tamponade effect of the herniated viscera, sometimes occurred in patients with Bochdalek hernia. These complications were found in Bochdalek hernia with gastrointestinal strangulation.

BACKGROUND: Curative treatment for hepatocellular carcinoma (HCC) is limited to hepatic resection (HR), radiofrequency ablation, and liver transplantation, but the value of particle therapy (PT) as an initial treatment remains unclear. This study aimed to compare the outcomes of HR and PT for single HCC. STUDY DESIGN: A total of 554 patients with single HCC without vascular invasion were enrolled from January 2000 to December 2015. Patients underwent either HR (n = 279) or PT (n = 275) as initial treatments. A one-to-one propensity score–matching analysis was performed to evaluate the overall survival (OS) and progression-free survival after dividing patients according to liver function as assessed by the modified albumin-bilirubin grade. RESULTS: The median OS (130 vs 85 months, p = 0.001) and progression-free survival (47 vs 30 months HR, p = 0.004) of HR were also significantly better than that of PT in the propensity score–matching cohort with modified albumin-bilirubin grade 1/2a (n = 145 per group). Meanwhile, in a propensity score–matching cohort with modified albumin-bilirubin grade 2b/3 (n = 53 per group), there were no significant differences in median OS and progression-free survival between HR and PT. CONCLUSIONS: HR may be preferable as an initial treatment for patients with single HCC without vascular invasion, especially those with preserved liver function. PT can be an acceptable alternative to HR for patients without surgical indication and/or impaired liver function.
