PURPOSE The aim of this study was to evaluate postoperative anal function of high-type imperforate anus after laparoscopically assisted anorectoplasty (LAARP). METHODS Between 2000 and 2002, LAARP was performed in 13 patients with high-type imperforate anus. Clinical data of the LAARP group were compared with the posterior sagittal anorectoplasty (PSARP)(More)
Immune responses are regulated by opposing positive and negative signals triggered by the interaction of activating and inhibitory cell surface receptors with their ligands. Here, we describe novel paired activating and inhibitory immunoglobulin-like receptors, designated myeloid-associated immunoglobulin-like receptor (MAIR) I and MAIR-II, whose(More)
OBJECTIVES This study investigated oxidative stress in the liver, by determining hepatic expression and serum levels of γ-glutamyltranspeptidase (GGT) and 8-hydroxy-2'-deoxyguanosine (8-OHdG) in different stages of nonalcoholic fatty liver disease (NAFLD), and assessed whether GGT can differentiate between the various stages of NAFLD. METHODS Expression(More)
PURPOSE Although various urologic complications have been reported after abdominoperineal pull-through and posterior sagittal anorectoplasty for the treatment of high-type imperforate anus, reports regarding complications after laparoscopically assisted anorectoplasty (LAARP) are surprisingly rare. Here, we discuss the potential complications of LAARP. (More)
PURPOSE Although intussusception has been reported as quite a rare cause of jejunoileal atresia (JIA), pediatric surgeons have noted the frequent presence of intussusception as well as volvulus at surgery. The aim of this study was to investigate the contribution of intrauterine intussusception and volvulus to the development of JIA. METHODS In 48(More)
PURPOSE In the recent years in Japan, an increasing number of patients with neuroblastoma (NB) are being treated by the "delayed local treatment (DL)" policy, undergoing surgery after the completion of high-dose chemotherapy with hematopoietic stem cell rescue (HDC). We reviewed the histopathological findings of second-look operations, including those of(More)
Mucin-histochemical characteristics of normal human colorectal mucosa were investigated utilizing Culling et al.'s staining method which distinguishes the mode of C8-O-acylation of sialomucins. Normal mucosae of cecum, ascending, transverse and descending colon and rectum were obtained from autopsy and biopsy material. Japanese colorectal mucosa stained(More)
