INTRODUCTION Endoscopic argon plasma coagulation (APC) is gaining widespread usage but its risk is underreported. CLINICAL PICTURE A 74-year-old man who received radical radiotherapy for gastric carcinoma 6 months ago was admitted for anaemia and maelena. Gastroscopy revealed haemorrhagic radiation gastritis. Endoscopic APC was performed but terminated when he complained of severe epigastric ...

Argon plasma coagulation (APC) is the most widely available technique for ablation of Barrett’s esophagus. When the argon plasma is applied, thermal injury to the epithelium results. The depth of injury is the function of the voltage, the gas flow, and the pressure applied to the probe. A series of 32 patients with high-grade dysplasia were treated with APC with 34 months of follow-up. Dysplasia

Dieulafoy disease of the bronchus is a rare condition. A 28-y-old male patient with recurrent exacerbations of hemoptysis (producing up to 300 mL) over the previous 4 y was admitted to our hospital following an acute episode. A 3-mm sessile lesion covered with somewhat ulcerated smooth mucosa was detected at the distal end of the left main bronchus, at the entrance to the upper lobe bronchus. B...

OBJECTIVE To evaluate the efficacy of complement by argon plasma coagulation to reduce the rate of residual or recurrent tumor after complete endoscopic piecemeal resection of large sessile colorectal adenomas. METHODS INCLUSION CRITERIA patients with large sessile colorectal adenomas (e" 20 mm), without morphological signs of deep infiltration, submitted to complete endoscopic piecemeal r...

Hemoptysis is a frequent manifestation of a wide variety of diseases, with mild to life-threatening presentations. The diagnostic workup and the management of severe hemoptysis are often challenging. Advances in endoscopic techniques have led to different new therapeutic approaches. Cold saline, vasoconstrictive and antifibrinolytic agents, oxidized regenerated cellulose, biocompatible glue, la...

Placement of a self-expanding metal stent (SEMS) is an effective method for palliation of a malignant biliary obstruction. However, metal stents can cause various complications, including stent migration. Distally migrated metal stents, particularly covered SEMS, can be removed successfully in most cases. Stent trimming using argon plasma coagulation may be helpful in difficult cases despite co...
