The SpyGlass probe was inserted into the catheter following successful cannulation, and cholangiopancreatoscopy was performed by a single operator. We retrospectively analyzed the successful visualization rate of this technique. Results:  Fifteen patients were included in this study. SpyGlass cholangiopancreatoscopy was technically successful in all patients. this website Successful visualization was obtained in nine patients (60%). The median SpyGlass procedure

time was 10 min. Cholangiopancreatoscopic diagnoses were as follows: bile duct carcinoma in three patients; intraductal papillary mucinous adenoma in two; and intraductal pancreatic stone, benign biliary stricture, gallbladder cholesterolosis, and gallbladder carcinoma in one each. There were no cases of post-ERCP pancreatitis. Conclusions:  While the low rate of successful visualization must be improved, single-operator cholangiopancreatoscopy using a SpyGlass probe through an ERCP catheter is a safe and effective procedure. “
“Although non-steroidal anti-inflammatory drugs

can induce intestinal injury, the mechanisms are not fully understood, and treatment has yet to be established. Heme oxygenase-1 (HO-1) has recently gained attention for anti-inflammatory and cytoprotective effects. This study aimed to investigate the effects of hemin, an HO-1 inducer, on indomethacin-induced enteritis in mice. Enteritis was induced by single subcutaneous administration of indomethacin (10 mg/kg) in male C57BL/6 mice. Hemin (30 mg/kg) was administered Birinapant clinical trial by intraperitoneal administration 6 h before indomethacin administration. Mice were randomly divided into four groups: (i) sham + vehicle; (ii) sham + hemin; (iii) indomethacin + vehicle; or (iv) indomethacin + hemin. Enteritis was evaluated by measuring ulcerative lesions. Myeloperoxidase activity was measured as an index of neutrophil accumulation. The mRNA expression of inflammatory cytokines and chemokines, such as tumor necrosis factor-α, Grape seed extract monocyte chemoattractant protein-1, macrophage inflammatory protein-1α, and keratinocyte chemoattractant, were analyzed

by real-time polymerase chain reaction. The area of ulcerative lesions, myeloperoxidase activity, and mRNA expression of inflammatory cytokines and chemokines were significantly increased in mice administrated with indomethacin compared with vehicle-treated sham mice. Development of intestinal lesions, increased levels of myeloperoxidase activities, and mRNA expressions of inflammatory cytokines and chemokines were significantly suppressed in mice treated with hemin compared with vehicle-treated mice. Protective effects of hemin were reversed by co-administration of tin protoporphyrin, an HO-1 inhibitor. Induction of HO-1 by hemin inhibits indomethacin-induced intestinal injury through upregulation of HO-1.
