There is pneumoperitoneum , which is probably explained by recent J - tube placement . There is increased opacity in the left lung , which could be due to increased pulmonary edema . Right lower lobe opacity is probably due to atelectasis and appears similar to 4 hr prior . Bilateral pleural effusions are small , larger on the right . There is no pneumothorax . Cardiac silhouette is borderline enlarged .
