[A Case of Resection of T2N0 Colon Cancer with Synchronous Solitary Lung Metastasis].

A 73-year-old man was referred to our hospital for anemia. He underwent a colonoscopy; a 15-mm Ip polyp and a 30- mm type 1 lesion were found in the sigmoid colon. Pathological examination results indicated a well-differentiated adenocarcinoma. Thoracic computed tomography(CT)revealed a mass lesion 12 mm in diameter in the left lung lobe. The patient underwent a laparoscopic sigmoidectomy and D3 lymph node dissection and was discharged in a good condition. He then underwent a diagnostic-therapeutic segmental pulmonary resection for the pulmonary mass. Postoperative pathological findings indicated pT1b(SM), ly0, v0 and pT2(MP), ly1, v1, pN0 for the 2 lesions of the colon. The pulmonary mass was diagnosed as a metastatic adenocarcinoma based on immunostaining examination(CK7: negative, CK20: positive, TTF-1: negative, and CDX-2: positive). The patient is currently under follow-up as an outpatient without recurrence.

Endoscopic papillary balloon dilation for a 7-year-old girl with choledocholithiasis.

A 7-year-old girl was referred to our hospital for severe abdominal pain and elevated serum levels of amylase and aminotransferase. Radiological examinations revealed choledocholithiasis. EPBD was performed under intravenous anesthesia using midazolam and ketamine chloride. After fluoroscopic confirmation of a bile duct stone, a dilation balloon (30 mm-long, 8 mm-diameter) was passed over the guidewire and placed across the papilla. The balloon was gradually inflated until the notch created by the papillary sphincter disappeared. At 4 atm, the notch disappeared and the pressure was maintained for 15 s. Stone extraction was performed by using a retrieval balloon catheter. Abdominal pain disappeared immediately after EPBD, and she resumed oral intake 2 days after EPBD. In conclusion, EPBD may be a safe and effective technique for the treatment of choledocholithiasis in pediatric patients. EPDB should be selected as a treatment for pediatric choledocholithiasis in view of its advantages of preserving papillary function.

Schinzel-Giedion syndrome: a further cause of early myoclonic encephalopathy and vacuolating myelinopathy.

Here, we report a male child with Schinzel-Giedion syndrome associated with intramyelinic edema detected on brain magnetic resonance imaging (MRI) and persistent suppression-burst pattern on electroencephalography (EEG) with erratic myoclonus of the extremities and face. Similar to nonketotic hyperglycinemia, Schinzel-Giedion syndrome may be recognized as another causative genetic disease of early myoclonic encephalopathy and vacuolating myelinopathy.
