Two cases of right congenital diaphragmatic hernia with stable respiratory condition: Two case reports.

ABSTRACT

INTRODUCTION: Right congenital diaphragmatic defect (CDH) has been reported poor prognosis. However, laterality of the defect as the prognostic factor is recent controversial topic. We experienced two cases of right CDH with relatively stable respiratory condition and good clinical course. PRESENTATION OF CASES Case 1 was a girl diagnosed with right CDH by fetal ultrasonography and delivered by planned caesarian section at 37 weeks, 3 days. Fetal MRI showed liver herniation into the right thoracic cavity. High frequency oscillatory ventilation with nitric oxide gas was administered until day 5. At surgery on day 8, we found defects in the right posterolateral diaphragm and sac herniation of the right side of the liver into the right thoracic cavity. The postsurgical course was uneventful, and she was discharged on day 41. Case 2 was a girl with suspected congenital jejunal atresia after fetal ultrasonography detected polyhydramnios and dilatation. She was delivered by normal vaginal delivery at 38 weeks, 5 days, and thoraco-abdominal X ray showed right CDH but no small intestinal atresia. Surgery performed on day 3 found liver herniation into the diaphragmatic defect. Subsequently, bacterial infection occurred and was treated with the antibiotics, but her respiratory condition remained stable. She was discharged on day 49. DISCUSSION: The volume of herniated abdominal organs is affected by the presence of a hernia sac or the size of the diaphragmatic defect. CONCLUSION: The size of diaphragmatic defect, but not the laterality of the diaphragmatic defect, may be an important prognostic factor in right CDH.
