- OK-432 therapy is effective for the treatment of macrocystic lymphatic malformations (LMs), but the optimal management of patients with microcystic LMs associated with large chylous pleural effusions or chylous ascites is not resolved. We performed thoracoscopic- or laparoscopic-guided injection of OK-432 for 2 patients with diffuse microcystic LMs accompanied by refractory chylous pleural effusion or chylous ascites. Both cases responded well to OK-432 therapy with improvement/resolution of fluid collections and associated symptoms.
- Spontaneous rupture and subsequent bile peritonitis are rare complications of choledochal cysts. Of these complications, the formation of a biliary pseudocyst is an unusual form, and its preoperative diagnosis is difficult. In this report, we describe 2 cases showing spontaneous rupture with biliary pseudocyst formation. Inflammatory tissue surrounded those pseudocysts, one of which was adjacent to the perforation and the other formed in the transverse mesocolon apart from the biliary tract. These pseudocysts were removed by careful dissection, and single-stage cyst excision with biliary reconstruction was successfully performed in both cases.
- The authors describe a newborn patient with mesenchymal hamartoma of the chest wall associated with pulmonary hypoplasia. A massive thoracic tumor was diagnosed by prenatal ultrasonography and magnetic resonance imaging at the 28th week of gestation. She was delivered through cesarean delivery at the 36th gestational week. Respiratory distress because of pulmonary hypoplasia necessitated neonatal intensive care. The tumor extensively involved the left hemithorax including all 12 ribs and the first 10 thoracic vertebrae, resulting in marked deformity of the thorax.
