Risk factors for patients hospitalized with recurrent colon diverticular bleeding: a single center experience.

Background/aims: Colonic diverticular bleeding (CDB) is a common cause of acute lower gastrointestinal bleeding. Patients with CDB are at increased risk for recurrence. Here, we aimed to evaluate the clinical course of patients with CDB and identify risk factors for recurrent CDB (rCDB).

Single balloon enteroscopy-guided endoscopic retrograde pancreatography for the treatment of a symptomatic pancreatic pseudocyst complicated by pancreaticojejunostomy stricture: A case report.

Rationale: Endoscopic treatment of a pancreatic pseudocyst complicated by pancreaticojejunostomy (PJ) stricture is challenging.

Patient Concerns: A 76-year-old woman presented with worsening abdominal pain and dyspepsia. She had been receiving adjuvant chemotherapy (capecitabine and cisplatin) for 4 months after pylorus-preserving pancreaticoduodenectomy (PPPD) for the treatment of extrahepatic cholangiocarcinoma.

Engulfment and Cell Motility 1 (ELMO1) Regulates Tumor Cell Behavior and Predicts Prognosis in Colorectal Cancer.

Background/aim: Engulfment and cell motility 1 (ELMO1) plays a crucial role in the process of migration, chemotaxis, and metastasis of tumor cells. ELMO1 has been implicated in the pathogenesis of various cancers. However, the distinct function of ELMO1 in colorectal cancer (CRC) is unclear.

Simple parameters predicting extrahepatic recurrence after curative hepatectomy for hepatocellular carcinoma.

Extrahepatic recurrence (EHR) after curative hepatectomy for hepatocellular carcinoma (HCC) is associated with a poor prognosis. We investigated the features of EHR and identified its predictive factors. This retrospective study included 398 treatment-naive patients who underwent curative hepatectomy for HCC at two tertiary hospitals.

Impact of Scope Exchange from a Long Single Balloon Enteroscope to a Gastroscope during Enteroscopy-Assisted Endoscopic Retrograde Cholangiopancreatography in Patients with Surgically Altered Anatomy.

Background/aims: : Endoscopic retrograde cholangiopancreatography (ERCP) in patients with surgically altered anatomy (SAA) is challenging to gastrointestinal endoscopists. The aim of this study was to evaluate the impact of scope exchange from a long single balloon enteroscope (SBE) to a gastroscope during SBE-assisted ERCP (SBE-ERCP) in patients with SAA.

Methods: Patients who underwent SBE-ERCP between February 2019 and October 2020 were retrospectively identified.

Septic shock due to after endoscopic ultrasound-guided biopsy of a splenic mass: A case report.

Background: Endoscopic ultrasound-guided fine needle aspiration or biopsy (EUS-FNA or FNB) has become a popular method for diagnosing various lesions of the gastrointestinal tract and surrounding tissue due to the accuracy and safety. To the best of our knowledge, no case report of severe infection after EUS-FNB of a solid lesion in the spleen has been described. Herein, we report a rare case of septic shock after EUS-FNB of a splenic mass.

Well-defined hollow nanochanneled-silica nanospheres prepared with the aid of sacrificial copolymer nanospheres and surfactant nanocylinders.

A new approach for synthesizing well-defined hollow nanochanneled-silica nanosphere particles is demonstrated, and the structural details of these particles are described for the first time. Positively charged styrene copolymer nanospheres with a clean, smooth surface and a very narrow size distribution are synthesized by surfactant-free emulsion copolymerization and used as a thermal sacrificial core template for the production of core-shell nanoparticles. A surfactant/silica composite shell with a uniform thickness is successfully produced and deposited onto the polymeric core template by charge density matching between the polymer nanosphere template surface and the negatively charged silica precursors and then followed by selective thermal decomposition of the polymeric core and the surfactant cylinder domains in the shell, producing the hollow nanochanneled-silica nanospheres.
