OK-432 therapy for chylous pleural effusion or ascites associated with lymphatic malformations
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.Development of bile duct cancer in a 26-year-old man after resection of infantile choledochal cyst
Anomalous arrangement of the pancreaticobiliary duct is considered to be a high-risk factor for biliary tract malignancy. We report a case of intrahepatic cholangiocarcinoma in a 26-year-old man after total resection of choledochal cyst with anomalous arrangement of the pancreaticobiliary duct at the age of 5 months. He had been doing well after total resection of the choledochal cyst; however, he suddenly presented with a spiky fever and abdominal pain in the right upper quadrant at the age of 26 years.Spontaneous rupture of choledochal cyst with pseudocyst formation—report on 2 cases and literature review
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.
