Endoscopic biliary stenting as the risk factor for cholangitis after endoscopic ultrasound in patients with biliary strictures.

Kenji Ikezawa, Minoru Shigekawa, Takuo Yamai, Takahiro Suda, Tadashi Kegasawa, Teppei Yoshioka, Ryotaro Sakamori, Tomohide Tatsumi, Tetsuo Takehara,

<h4>Background and aim</h4>Endoscopic ultrasound (EUS) and EUS-guided fine needle aspiration (FNA) are established as efficient and safe diagnostic modalities. However, the risk of cholangitis after EUS/EUS-FNA (post-EUS cholangitis) in patients who have biliary strictures has not been fully examined.<h4>Methods</h4>We retrospectively reviewed 136 consecutive inpatients with biliary strictures who received EUS/EUS-FNA ...

The immune system plays important roles in pancreatic cancer. MHC class I-chain-related proteins A and B (MICA/B) and UL16-binding proteins (ULBPs) are known natural killer group 2D (NKG2D) ligands. Soluble NKG2D ligands can inhibit the activation of Natural killer (NK) cells. In pancreatic cancer, soluble ULBPs are relatively unstudied in ... Read more >>

<h4>Background</h4>International consensus guidelines 2012 for intraductal papillary mucinous neoplasia (IPMN), defined two characteristics: high-risk stigmata (HRS) and worrisome features (WF). Patients with WF require detailed examination including cytology. However, routine endoscopic retrograde cholangiopancreatography (ERCP) for cytology is not recommended in the guidelines due to risk of post-ERCP pancreatitis (PEP). Our ... Read more >>

Takashi Ueda, Kouhei Miyoshi, Tadashi Kegasawa, Hirokazu Inoue, Minoru Fujita, Osamu Tatsumi, Hiroyuki Fukui,

We report five-metallic stent placement cases for malignant duodenal stenosis. Two of them received a placement of Ultraflex by over-the-wire (OTW) procedure, and the other three received a placement of WallFlex by through-the-scope (TTS) procedure. We assessed the baseline characteristic of the patient, procedural time and food intake after the ... Read more >>
