Background And Aim: Chromoendoscopy with the use of indigo carmine (IC) dye is a crucial endoscopic technique to identify gastrointestinal neoplasms. However, its performance is limited by the endoscopist's skill, and no standards are available for lesion identification. Thus, we developed an artificial intelligence (AI) model to replace chromoendoscopy.

Background: Preventing unplanned extubation has become a difficult problem for nursing staff because the catheter is stiff, fine and long.
Design: A total of 114 cases that experienced nasobiliary drainage after endoscopic retrograde cholangiopancreatography for the first time in our hospital from April 2015-July 2016 were enrolled in this study.
Aim: To investigate the efficacy and safety profile of pancreatic duct (PD) stent placement for prevention of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP).
Methods: We performed a search of MEDLINE, EMBASE, and Cochrane Library to identify randomized controlled clinical trials of prophylactic PD stent placement after ERCP. RevMan 5 software provided by Cochrane was used for the heterogeneity and efficacy analyses, and a meta-analysis was performed for the data that showed homogeneity.
Objective: This study compared the therapeutic benefits and complication rates of small endoscopic sphincterotomy plus large-balloon dilation (ESLBD) with those of endoscopic sphincterotomy (EST) alone for large bile duct stones.
Methods: We compared prospectively ESLBD group (n=63) with conventional EST group (n=69) for the treatment of large bile duct stones (≥15mm). Mechanical lithotripsy was performed when the stone could not be removed using a normal basket.
Objective: The aim of this study was to evaluate the detection rate accuracy of Double-balloon Enteroscopy (DBE) after Capsule Endoscopy (CE) in patients with suspected small bowel diseases.
Methodology: From January 2009 to March 2012, sixty-two patients with obscure small bowel diseases who underwent CE followed by DBE were included in this study. Introduction of the endoscope by DBE was either orally or anally according to CE.
Background And Aim: Epinephrine sprayed on the papilla may reduce papillary edema and prevent acute pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP). The aim of this study was to evaluate the effects of localized irrigation with epinephrine saline for prevention of post-ERCP pancreatitis (PEP).
Methods: A total of 941 patients who were scheduled for ERCP were recruited into this study.
Background: Endoscopic submucosal dissection (ESD) is a promising technique for the treatment of large, pre- and early malignant gastrointestinal lesions.
Objective: To assess the rates of en bloc resection, incidence of complications, procedure times and therapeutic outcomes of ESD using an insulated-tip diathermic knife; and to investigate predictors of these outcomes based on the final pathological features of biopsy specimens.
Methods: One hundred twenty patients with endoscopically suspected gastric epithelial tumours who were treated with ESD from January 2006 to December 2009 were evaluated.
[HCCR-2 enhances the division and proliferation of SMMC 7721 via PI3K/Akt pathway].

Objective: To observe the biological changes of SMMC 7721 cell line which was stably transfected with HCCR-2 gene and to study the molecular mechanism of HCCR-2 expression in SMMC 7721 cell line.
Methods: SMMC7721 cells were transfected with HCCR-2-pEGFP-N1 and pEGFP-N1 by lipofectmine 2000 and the transfectants were selected and confirmed using Western-blot technique. Cell cycles were tested by flow cytometry.
