Analysis of risk factors for post-endoscopic papillectomy bleeding.

Background: Endoscopic papillectomy (EP) is an effective treatment for ampullary lesions but technically challenging because of anatomical specificities concerning the high rate of adverse events. Bleeding is one of the most feared complications and can be potentially life-threatening.

Aim: To study the risk factors for bleeding after EP are presented with the goal of establishing preventive measures.

Novel endoscopic papillectomy for reducing postoperative adverse events (with videos).

Background: Pancreatic adenoma can potentially transform into adenocarcinoma, so it is recommended to be resected surgically or endoscopically. Endoscopic papillectomy is one of the main treatments for papillary adenoma, and bleeding, perforation, and pancreatitis are the most frequent and critical adverse events that restrict its wider use. There is no standard procedure for endoscopic papillectomy yet.

Clinical Features, Diagnosis, and Treatment Strategies of Gastrointestinal Diaphragm Disease Associated with Nonsteroidal Anti-Inflammatory Drugs.

Background. To demonstrate the clinical features, diagnosis, and treatment of nonsteroidal anti-inflammatory drug- (NSAID-) induced diaphragm disease (DD). Methods.

[Effectiveness and safety of endoscopic ultrasound-guided transgastric or transpapillary drainage in treating pancreatic pseudocyst].

Objective: To explore the effectiveness and safety of endoscopic transgastric or transpapillary drainage in treating pancreatic pseudocysts.

Methods: The clinical data of 15 patients with pancreatic pseudocyst who underwent endoscopic ultrasound-guided transgastric or transpapillary drainage in the Chinese PLA General Hospital between June 2004 and February 2013 were retrospectively analyzed. Also, we reviewed the relevant Chinese literature in the China Academic Journal Network Publishing Database (from 1994 to 2012) and VIP China Science and Technology Journal Database (from 1989 to 2012) using the key words "pancreatic pseudocyst and drainage".

[The difference in diagnosis rate of different diagnostic criteria of autoimmune pancreatitis and its major influential factors].

Objective: To discuss the difference in diagnostic criteria of autoimmune pancreatitis(AIP) and its major influential factors, so as to provide guidance for AIP diagnosis and treatment.

Methods: The clinical data of 561 cases of chronic pancreatitis admitted to PLA General Hospital from June, 2008 to January, 2013 were retrospectively reviewed and analyzed. Data were extracted and analyzed to summarize the reasons of the differences in AIP diagnosis rate diagnosed by different diagnostic criteria.

Verification of the Tokyo guidelines for acute cholangitis secondary to benign and malignant biliary obstruction: experience from a Chinese tertiary hospital.

Background: The lack of widely-accepted guidelines for acute cholangitis largely lags behind the progress in medical and surgical technology and science for the management of acute cholangitis. This study aimed to verify the Tokyo guidelines for the management of acute cholangitis and cholecystitis of 2007 edition (TG07) in patients with obstructive cholangitis due to benign and malignant diseases.

Methods: The patients were retrieved from our existing ERCP database.

Is prophylactic somatostatin effective to prevent post-endoscopic retrograde cholangiopancreatography pancreatitis or hyperamylasemia? A randomized, placebo-controlled pilot trial.

Background: Effects of prophylactic somatostatin on post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) and hyperamylasemia remain inconclusive. This study aimed to examine whether high-dose, long-term continuous infusion of somatostatin can reduce the incidence of PEP and post-ERCP hyperamylasemia.

Methods: This was a randomized, placebo-controlled pilot trial.

Gastric body diaphragm-like stricture as a rare complication of nonsteroidal anti-inflammatory drugs.

Increased risk due to nonsteroidal anti-inflammatory drugs (NSAIDs) therapy has been observed in patients. Although diaphragm-like stricture in the small bowel and colon induced by NSAIDs therapy has been rarely reported, gastric body diaphragm-like stricture has not been reported. We describe the first case of gastric body diaphragm-like stricture due to NSAIDs in a 44-year-old male patient who was successfully treated by an endoscopic approach to avoid complicated surgery.

[Causes and management of ischemic-type biliary lesion after orthotopic liver transplantation].

Objective: To discuss the causes, diagnosis, prophylaxis and treatment of ischemic-type biliary lesions (ITBLs) following orthotopic liver transplantation (OLT).

Methods: A retrospective analysis was performed for 326 OLT patients from January 2002 to January 2009. The post-OLT etiological factors and treatment of ITBL cases were analyzed.

Treatment of gastric varices by endoscopic sclerotherapy using butyl cyanoacrylate: 10 years' experience of 635 cases.

Background: Gastric varices (GV) are life-threatening for patients with portal hypertension. Endoscopic injection with butyl cyanoacrylate (BC), the mainstay of the therapy for GV, has been reported to be effective for hemostasis of bleeding varices, but its efficacy in the obliteration of GV and impact on the survival of patients still needs clarification. Here we summarized our experience of 10 years' practice to evaluate the efficacy and safety of endoscopic therapy using BC for GV patients.

Stent implantation through rendezvous technique of PTBD and ERCP: the treatment of obstructive jaundice.

Objective: To study the technical method and clinical value of stent implantation through the rendezvous technique of percutaneous transhepatic biliary drainage (PTBD) and endoscopic retrograde cholangiopancreatography (ERCP) in patients with obstructive jaundice.

Methods: Thirty-six patients with obstructive jaundice underwent the rendezvous technique of PTBD and ERCP after initially unsuccessful ERCP.

Results: The procedure of 36 cases were all successful.

Intraductal ultrasonography and endoscopic retrograde cholangiography in diagnosis of extrahepatic bile duct stones: a comparative study.

Background: Intraductal ultrasonography (IDUS) is highly accurate in detection of extrahepatic bile duct stones. This study was to compare the accuracy of IDUS and endoscopic retrograde cholangiography (ERC) in the diagnosis of extrahepatic bile duct stones.

Methods: Thirty patients suspected of extrahepatic bile duct stones on B ultrasonography, CT, or MRI were enrolled for study.
