A snare-assisted peroral direct choledochoscopy and pancreatoscopy using an ultra-slim upper endoscope: A case series study.

Objective: To evaluate the feasibility, effectiveness and safety of a new snare-assisted peroral direct choledochoscopy/pancreatoscopy (PDCPS) technique.

Methods: From November 2014 through December 2016, 20 consecutive patients with indications for PDCPS were enrolled in this observational study. Endoscopic retrograde cholangiography was initially performed using a conventional duodenoscope, and endoscopic papillary balloon dilation was performed.

Tissue performance of bladder following stretched electrospun silk fibroin matrix and bladder acellular matrix implantation in a rabbit model.

The goal of this study was to investigate the tissue performance of bladder following stretched electrospun silk fibroin matrix (SESFM) implantation compared with bladder acellular matrix (BAM). We compared SESFM with BAM based on porosity and pore size. Scaffolds were separately transplanted into opposite walls of the bladder of 30 rabbits after stripping the bladder mucosa and smooth muscle (1.

[Diagnostic value of selective small bowel enteroclysis in imageology of intestinal obstruction: clinical analysis of 98 cases].

Objective: To improve the diagnosticability of selective enteroclysis in the area of intestinal obstruction, by reviewing the cases of selective intestinal enteroclysis through a naso-intestinal decompression tube, and evaluating its diagnostic concordance level and the influence factors.

Methods: The selective enteroclysis was different from traditional enteroclysis; it utilized a naso-intestinal decompression long tube to perform local intestinal opacification. In the four years between Apr.

Adult colonoscopy or single-balloon enteroscopy-assisted ERCP in long-limb surgical bypass patients.

Objective: The aim of this study was to evaluate the usefulness of adult colonoscopy or single-balloon enteroscopy (SBE)-assisted endoscopic retrograde cholangiopancreatography (ERCP) in long-limb surgical bypass patients.

Methods: Retrospective analysis of 16 patients with long-limb surgical bypasses who underwent therapeutic ERCP because of suspected pancreaticobiliary diseases. Small-bowel intubation was performed by peroral adult colonoscopy or SBE.

[Role of peroxisome proliferators-activated receptor-gamma in the chemical prevention therapy of sulindac for precancerous lesions of rats].

Objective: To understand whether peroxisome proliferators-activated receptor-gamma (PPAR-gamma) plays an important role in the chemopreventive effect of sulindac on precancerous lesions (aberrant crypt foci, ACF) of rats.

Methods: Male Sprague-Dawley rats were used in this study and raised in Special Pathogen Free room. Sulindac was the main research object.
