Prospective analysis of glycemic variability in patients with severe traumatic brain injury: modified Leuven's adjustment process versus conventional adjustment process.

Objective This study was performed to evaluate the effect of two different methods of controlling glycemic variability (GV) in patients with severe traumatic brain injury (STBI) undergoing surgery. Methods Patients with STBI were randomly grouped into a conventional adjustment process (CAP) group and modified Leuven's adjustment process (mLAP) group. Each group included 50 patients.

New precut sphincterotomy for endoscopic retrograde cholangiopancreatography in difficult biliary duct cannulation.

Aim: To retrospectively investigate the effect and safety of various new type precut sphincterotomy techniques (VNTPST) in endoscopic retrograde cholangiopancreato-graphy (ERCP) due to difficult biliary duct cannulation (DBC).

Methods: A plough-like pull-type sphincterotome (PLPTS) or improved short nose sphincterotome or improved needle knife was applied. VNTPST was carried out in 30 of 280 patients, whose biliary tract could not be exposed well or deep cannulation was difficult to perform during ERCP with traditional methods.
