Congenital diaphragmatic hernias: Severe defect grade predicts the need for fundoplication.

Over one-third of infants with congenital diaphragmatic hernia (CDH) eventually require a Nissen fundoplication (NF). We examined pre- and intraoperative predictors for need of a NF in children undergoing CDH repair to elucidate, which patients will need a later NF.A retrospective analysis of all consecutive patients undergoing CDH repair at our institution from 2008 to 2018 was performed. Patients who underwent a NF were compared to those who did not (noNissen). Logistic regression analysis was performed to find independent predictors for NF in patients undergoing CDH repair. Severe Defect Grade was defined as defect >50% of the hemidiaphragm and intrathoracic liver.One hundred twenty-six patients were included, 42 (33%) underwent NF at a median of 61 days after CDH repair. Intrathoracic liver was more frequent in the NF (71%) versus noNissen (45%) group (P = .008). Absence of >50% of the hemidiaphragm was more frequent in the NF group (76% vs 31%, P < .001). Severe Defect Grade emerged as independent predictor for NF (odds ratio 7, 95% confidence interval 3-16, P < .001).Severe Defect Grade emerged as independent predictor for NF after CDH repair.

Late complications of biliary atresia: hepatopulmonary syndrome and portopulmonary hypertension.

Children with biliary atresia (BA) following Kasai portoenterostomy have a high risk for portal hypertension, however, while variceal and hemorrhagic complications have been more commonly studied, less frequent but no less possibly devastating complications of hepatopulmonary syndrome (HPS) and portopulmonary hypertension (PPH) remain less well understood. HPS and PPH both occur in a setting of portal hypertension, however, paradoxically patients with HPS develop pulmonic vasculature dilation leading to shunting and hypoxia, while those with PPH develop an opposite progression of pulmonary vasoconstriction eventually leading to cor pulmonale and decompensation. Given the near diametric evolution of diseases, HPS and PPH differ widely in therapy, though liver transplantation can have a role for treatment in either disease state. We reviewed our series of 320 pediatric patients with biliary atresia treated at our institution over 44 years, highlighting two cases that developed HPS and PPH, respectively, using these cases in further discussion of hepatopulmonary syndrome and portopulmonary hypertension regarding disease etiology, diagnosis, management, and prognosis. The complicated nature of these processes demand a careful multidisciplinary approach to optimize patient outcomes, including mindful evaluation for when transplantation may offer benefit.
