Introduction and study aims:  Gastric antral vascular ectasia (GAVE) is a mucosal abnormality associated with multiple conditions, most notably cirrhosis and systemic sclerosis, that causes indolent gastrointestinal bleeding. It is primarily managed with endoscopic therapy. Traditionally, GAVE is endoscopically ablated using argon plasma coagulation (APC) but radiofrequency ablation (RFA) is emerging as an alternative modality. No prior comparison of the 2 modalities has been published...

Intramural duodenal hematoma (IDH) is a rare complication in endoscopic management of ulcer hemorrhage. Usually noted in cases of blunt abdominal trauma, non-traumatic IDHs have been reported in individuals on anticoagulation, with blood disorders, pancreatic diseases and in endoscopic procedures such as biopsy, sclerotherapy and argon plasma coagulation. Patients may be asymptomatic or present with acute blood loss anemia, abdominal pain or vomiting. We report a case of an 83-year-old man with melena and syncope who underwent endoscopy for bleeding ulcer control and subsequently developed acute pancreatitis due to an acute IDH...

BACKGROUND: This prospective, randomized, controlled, single-blinded study investigates the peritoneal adhesion formation of HybridAPC (waterjet elevation of the peritoneum with subsequent argon plasma coagulation) versus only waterjet (elevation with the same instrument, but without subsequent argon plasma coagulation) in a rat model (24 female Wistar rats). MATERIALS AND METHODS: Bilateral lesions were created on the abdominal wall with HybridAPC on one sidewall and waterjet elevation on the other sidewall of the peritoneum in a standard fashion...

Argon plasma coagulation (APC) is an electrosurgical technique which can be used to ablate skin lesions with limited invasion depth into dermal tissue. Hence, APC might be well suited for the removal of epithelial tumours. However, there are no data on the effects of APC on human skin tissue. Thus, the aim of this study was to determine the extent of epidermal and dermal damage after APC of human skin. We performed APC ex-vivo on 91 freshly resected human skin samples, which were obtained after reconstructive surgical closures in actinically damaged areas...

BACKGROUND AND AIM: Endoscopic snare papillectomy (ESP) is an effective treatment for ampullary adenoma. Argon plasma coagulation (APC) is widely used as an additional method to control bleeding or ablate the residual tumor. However, the efficacy of this procedure has not yet been fully evaluated. This study aimed to evaluate the usefulness of APC as an additional method to ESP. METHODS: Patients who underwent ESP for ampullary adenoma between September 2005 and September 2015 were retrospectively reviewed...

Klippel-Trenaunay syndrome is characterised by vascular abnormality which increases the risk of thromboembolism and haemorrhage. Physiological changes in pregnancy pose an increased risk to these complications. Being an uncommon disorder, there is limited literature about the management of women with pregnancy and Klippel-Trenaunay syndrome. We report in detail two of three pregnancies in a woman with Klippel-Trenaunay syndrome who had repeated episodes of haematochezia leading to anaemia, managed with Argon laser Photo-Coagulation in pregnancy and also reviewed the complications and the management of pregnant women with Klippel-Trenaunay syndrome...

We investigated the possible neuroprotectant and intraocular pressure (IOP) lowering effects of intravitreous injection of sodium hydrosulfide (NaSH) in a rodent model of experimental glaucoma. Glaucoma currently is treated by controlling IOP using medications and/or surgery. These methods are not entirely adequate for all patients. We divided 24 rats into three groups. For the control group, the right eye was treated with intravitreous saline. For the glaucoma group, ocular hypertension was induced by photocoagulating three episcleral veins and the limbal plexus of the right eye using an argon laser, then saline was injected into the vitreous of these eyes during the third week...

We present a rare case of giant endobronchial hamartoma coexisting with lung atelectasis for more than 3 years. The small specimen initially biopsied via bronchoscope did not reveal tissue features, but some features were suspicious for squamous cell carcinoma. The lesion was removed completely using snare electrocautery combined with argon plasma coagulation via flexible fiberoptic bronchoscopy. The patient made a satisfactory recovery, and a pathological diagnosis was made. This could be a useful option in selected endobronchial tumors...

BACKGROUND AND AIMS: As a result of previous manipulation or submucosal invasion, GI lesions referred for EMR frequently have flat areas of visible tissue that cannot be snared. Current methods for treating residual tissue may lead to incomplete eradication or not allow complete tissue sampling for histologic evaluation. Our aim is to describe dissection-enabled scaffold-assisted resection (DeSCAR), a new technique combining circumferential ESD with EMR for removal of superficial non-lifting or residual "islands" with suspected submucosal involvement/fibrosis...

A 65-year-old man presented with obstructive pneumonia due to squamous cell carcinoma of the lung, which invaded the right main bronchus. Argon plasma coagulation was performed, which reduced his symptoms. Right pneumonectomy was performed after preoperative chemotherapy; the pathological diagnosis was T3N1M0 Stage IIIA. Fifteen months after surgery, he presented with bloody sputum. Bronchoscopy showed multiple endotracheal tumors, and a pathological examination revealed squamous cell carcinoma; the same histology as the primary lung cancer...

A small proportion of gastrointestinal angiodysplasia bleeding leads to chronic blood cell transfusion dependency. There are no guidelines supporting decision-making among various treatments in patients with gastrointestinal angiodysplasia bleeding. When endoscopic argon plasma coagulation is ineffective, the angiogenesis inhibitors thalidomide and octreotide can be considered. We describe a 77-year-old woman who had side effects of these angiogenesis inhibitors, which caused her to have continued bleeding...

Roux-en-Y gastric bypass (RYGB) is the most commonly performed bariatric procedure. Despite its high efficacy, some patients regain part of their lost weight. Several endoscopic therapies have been introduced as alternatives to treat weight regain, but most of the articles are relatively small with unclear long-term data. To systematically assess the efficacy of endoscopic therapies for weight regain after RYGB. We searched MEDLINE, EMBASE, Scopus, Web of Science, Cochrane, OVID, CINAHL/EBSCo, LILACS/Bireme, and gray literature...
