Vascular-targeted photodynamic therapy of gastric antral vascular ectasia (GAVE).

Background And Study Aim: Vascular-targeted photodynamic therapy (V-PDT) has been used for several benign vascular diseases. The aim of this pilot study was to demonstrate the potential benefits of VPDT in the treatment of gastric antral vascular ectasia (GAVE).

Patients And Methods: Data from patients with GAVE (n=5) who underwent endoscopic V-PDT were analyzed retrospectively.

Is single-operator peroral cholangioscopy a useful tool for the diagnosis of indeterminate biliary lesion? A systematic review and meta-analysis.

Background: Differentiating between malignant and benign biliary lesions is critical in clinical practice but is difficult.

Objective: To systematically evaluate the diagnostic performance of single-operator peroral cholangioscopy on indeterminate biliary lesions.

Design: A systematic review and meta-analysis.

[A retrospective analysis of ectopic varices in gastrointestinal tract diagnosed by endoscopy].

Objective: To understand the incidence, causes, clinical manifestations and treatment of ectopic varices (EV) in gastrointestinal (GI) tract.

Methods: GI endoscopic examinations were carried out in 99 783 patients from January 2004 to October 2012 in General Hospital of PLA. Sixty-four cases of ectopic varices in GI tract were discovered.

The potential of photodynamic therapy to treat esophageal candidiasis coexisting with esophageal cancer.

Background: Photodynamic therapy (PDT) has been used in recent years to deal with fungal infections because of the prevalence of fungi resistance to drugs. However, PDT for gastrointestinal fungal infection has not been reported. This study was conducted to assess the potential of PDT to deal with esophageal candidiasis.

Endoscopic lithotripsy for gastric bezoars by Nd:YAG laser-ignited mini-explosive technique.

Until now, there still has no standard treatment option to deal with gastric bezoars. This respective study was conducted to evaluate the safety and efficiency of Nd:YAG laser-ignited mini-explosive technique for the treatment of gastric bezoars. Two hundred sixty patients with 285 gastric bezoars were treated by endoscopic lithotripsy with Nd:YAG laser-ignited mini-explosive technique.

Endoscopic holmium:YAG laser ablation of early gastrointestinal intramucosal cancer.

Various endoscopic techniques are being increasingly used in early gastrointestinal (GI) cancer. The holmium: yttrium-aluminum-garnet (Ho:YAG) laser has precise tissue cutting ability and good hemostatic properties and has been widely applicated to soft tissue, but the use of endoscopic Ho:YAG laser ablation for early gastrointestinal cancer has not been reported. Twenty patients with biopsy-proven early GI cancer who had a high surgical risk or refused surgery were treated by endoscopic Ho:YAG laser ablation.

Vascular targeted photodynamic therapy for bleeding gastrointestinal mucosal vascular lesions: a preliminary study.

Background: Vascular-targeted photodynamic therapy (V-PDT) has shown good selectivity and efficacy in the treatment of certain types of vascular disease, including port wine stains, age-related macular degeneration, and esophageal varices. This study was conducted to test the efficacy and safety of V-PDT in the treatment of gastrointestinal (GI) bleeding caused by the abnormal dilatation of capillaries.

Methods: Patients with bleeding GI mucosal vascular lesions treated with V-PDT were included in this retrospective study.

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.

Experience in sclerotherapy for esophagogastric variceal bleeding.

Objective: To evaluate the efficacy of endoscopic variceal sclerotherapy (EVS) for esophago gastric variceal bleeding.

Methods: A retrospective analysis was made on 1010 patients with esophagogastric variceal bleeding who underwent sclerotherapy, among whom there were 834 patients with cirrhosis, 160 with hepatocarcinoma, 12 with Budd-Chiari syndrome and 4 with congenital liver fibrosis. Totally, 3203 sessions of sclerotherapy were performed, including 602 sessions of emergency sclerotherapy and 2601 of selective surgery.
