INTRODUCTION Earlier reports of laparoscopic adrenalectomy (LA) for adrenal myelolipoma are limited. PRESENTATION OF CASE Between June 2000 and September 2012, we performed right adrenal resections using LA and open adrenalectomy (OA) in patients with myelolipoma (n = 3 and n = 3, respectively). Then, we evaluated patients' background characteristics and(More)
Although most sporadic colorectal cancers (CRC) are thought to develop from protruded adenomas through the adenoma-carcinoma sequence, some CRC develop through flat lesions, so-called laterally spreading tumors (LST). We previously analyzed epigenetic aberrations in LST and found that LST are clearly classified into two molecular subtypes:(More)
Esophageal endoscopic submucosal dissection (ESD) is technically difficult. To make it safer, we developed a novel method using overtube with a traction forceps (OTF) for countertraction during submucosal dissection. We conducted an ex vivo animal study and compared the clinical outcomes between OTF-ESD and conventional method (C-ESD). A total of 32(More)
The division of the embryonic cloaca is the most essential event for the formation of digestive and urinary tracts. The defective development of the cloaca results in anorectal malformations (ARMs; 2-5 per 10,000 live births). However, the developmental and pathogenic mechanisms of ARMs are unclear. In the current study, we visualized the epithelia in the(More)
We report a case of a gastrointestinal stromal tumor (GIST) of the stomach that demonstrated a stepwise progression from low- to high-grade malignancy. The patient had been followed for a small gastric submucosal tumor that had turned malignant after 8 years of indolence, manifested by tarry stools. The tumor was enucleated, and gastric GIST was diagnosed.(More)
