[Transudative chylothorax complicated with liver cirrhosis due to primary biliary cholangitis:case report].

A 70-year-old woman who was diagnosed with liver cirrhosis as a result of primary biliary cholangitis and heart failure by myocardial infarction 1 month ago complained of dyspnea and was admitted to our hospital. Image inspections showed right massive pleural effusion, so we performed thoracentesis and drainage. Despite no history of trauma or malignancy, we obtained milky white-yellow pleural effusion by drainage and it turned out to be transudative chylothorax. Because there were no signs of heart failure exacerbation or other diseases, we suspected that the transudative chylothorax was caused by liver cirrhosis. For cardioprotection and improvement of portal hypertension, we used conservative treatments such as increasing diuretic dosage, inducing branched-chain amino acids, and switching ß-blocker medication from bisoprolol to carvedilol. Even though thoracentesis and drainages were performed twice for improvement of hypoxemia, right pleural effusion gradually decreased with the disappearance of dyspnea and she was discharged from our hospital on the 20th hospital day. We have been following her for 10 months and have found no evidence of pleural effusion. Although liver cirrhosis complicated with chylothorax is rare, several case reports have shown all patients with chylothorax caused by liver cirrhosis were transudative. It is assumed that portal hypertension by liver cirrhosis is associated with transudative chylothorax. This patient's case is complicated by insufficient ascites to be punctured. Other studies have reported that chylothorax occurs as a result of chylous ascites passing through the diaphragm in patients with liver cirrhosis;however, our case does not appear to fit the mechanism. Another study has proposed that portal hypertension increased lymph fluid production in the liver, this flow in the thoracic duct, and increased intrathoracic pressure resulting in the occurrence of chylothorax. We believe that switching ß-blocker medication from bisoprolol to carvedilol is one of the reasons this patient's right chylothorax gradually decreased. According to one case study, a nonselective ß-blocker improves chylothorax by lowering portal hypertension. As a result, a nonselective ß-blocker such as carvedilol that improves portal hypertension may contribute to a reduction in cirrhotic chylothorax in this case. Bisoprolol, a selective ß-blocker, has no effects on portal pressure and intrathoracic pressure. Our case report suggests that portal hypertension causes transudative chylothorax complicated by liver cirrhosis and that medication for portal hypertension improvement, such as a nonselective ß-blocker, is one option for treatment.

Palliative radiation therapy for bleeding from gastric cancer: A case series of seven patients.

The hemostatic effect of palliative radiation therapy (RT) for unresectable gastric cancer is unclear. We performed palliative RT (20 Gy in 5 fractions or 30 Gy in 10 fractions) in 7 consecutive patients with bleeding. The number of blood transfusions decreased significantly post-RT, supporting the hemostatic effect of palliative RT.
