REVIEW
Semra Bilaçeroğlu
Endobronchial ablative therapies, such as mechanical debulking, laser therapy, electrocautery, argon plasma coagulation, cryotherapy, brachytherapy, photodynamic therapy, microdebrider bronchoscopy, resector balloon deobstruction, and intratumoral chemotherapy, are performed through a rigid or flexible bronchoscope in palliating or curing symptomatic malignant and benign airway lesions to improve symptoms, quality of life, and survival. Technical factors together with patient- and lesion-specific features determine the therapy of choice, as each therapy is different in capacity, limitation, and complications...

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...

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...

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: Due to previous manipulation or submucosal invasion, GI lesions referred for endoscopic mucosal resection (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...

BACKGROUND: Nonthermal atmospheric pressure plasma (NTAPP) has recently received attention as a novel tool in medicine. It is thought that plasma components yield plasma effects such as sterilization, blood coagulation, and wound healing. These effects are produced without thermal damage. We investigated the blood coagulation effect of NTAPP by using a multigas plasma jet. MATERIALS AND METHODS: Multigas plasma jets can generate NTAPP by several gas species. In this study, argon, oxygen, helium, nitrogen, mock air, and carbon dioxide were used to generate NTAPP, and blood coagulation times were compared with each plasma-treated sample...

BACKGROUND: The development of central airway obstruction during malignant diseases is an important cause of morbidity and mortality. Endobronchial therapies can decrease the patient's symptoms and improve quality of life. Here, we compare airway recanalization methods: argon plasma coagulation with mechanical tumor resection (APC + MTR) and cryorecanalization (CR efficiency, complications, restenosis rate, and time to restenosis) in patients with malignant exophytic endobronchial airway obstruction...

BACKGROUND: Benign central airway tumors are very rare diseases. Their unspecific symptoms are responsible for late diagnosis. Endoscopic interventions with different techniques and tools are widely used for their treatment. However, in certain cases interventional endoscopy might be unsuccessful and therefore other methods such as high-dose-rate brachytherapy could be a therapeutic option. CASE PRESENTATION: A 76-year-old white German woman was referred to our clinic for an endoscopic treatment of a recurrent granulation polyp in her left main bronchus...
