Primary hyperparathyroidism revealed by thoracic spine brown tumor and peptic ulcer bleeding is rare. We presented a case of 33-year-old male patient who was admitted with paraplegia. Thoracic spine magnetic resonance imaging (MRI) showed extradural lesion at T4 level. He underwent surgical decompression in T4. According to histopathologic finding and elevated serum parathormone (PTH) and hypercalcemia (total serum calcium 12.1 mg/dL), the diagnosis of brown tumor was down. Ultrasonography of his neck showed a well-defined lesion of 26 × 14 × 6 mm...

INTRODUCTION: Chronic radiation proctitis (CRP) usually develops 90 days or more after radiation. Currently, there is no standard available for the treatment of CRP. In argon plasma coagulation, monopolar diathermy is used to ionise the argon gas which coagulates the telengiectatic vessels in a noncontact fashion. However, there are very few studies which have reported its use in extensive CRP. We report the efficacy and safety of APC in seven patients with recurrent, extensive grade 3 radiation proctitis...

A 68-year-old male was admitted for evaluation of an endobronchial mass obstructing the right middle lobe (RML) and right lower lobe (RLL) of the lung. Flexible bronchoscopy revealed a notable endobronchial lesion in the bronchus intermedius that completely obstructed the RML and the RLL. Argon plasma coagulation (APC) at 30 watts and gas flow at 0.8 liters/minute to 1 liter/minute were applied to the tumor. In the recovery room, the patient was discovered to have a left-sided facial droop and left-sided weakness...

Gastric antral vascular ectasia (GAVE) is known to be characterized by red patches or spots in a diffuse or linear array in the antrum of the stomach. The precise etiology of GAVE remains to be elucidated. Argon plasma laser coagulation (APC) has been used to control oozing from GAVE; however, there is no satisfactory long-term effect of APC in the control of oozing from GAVE. An acid reducer is used after APC because even physiological acid exposure might delay post-APC ulcer healing. We describe the case of a patient who had used an acid reducer and experienced repeated gastrointestinal hemorrhage due to GAVE...

OBJECTIVE: Recurrent tracheoesophageal fistula (TEF) can be a diagnostic and therapeutic challenge. Traditional treatment is thoracotomy, which carries significant morbidity and technical difficulty especially in a previously operated field. Recently, endoscopic techniques have been advocated as a primary approach for treatment of recurrent TEF prior to open repair. This case report describes the endoscopic technique used to address a recurrent TEF. The existing literature of all reported endoscopic cauterization methods is reviewed...

Gastrointestinal angiodysplasia (GIA) is an acquired vascular superficial lesion, which presents typically as a bright red, irregular, round-shaped, slightly elevated lesion. GIAs are often seen in patients over 60 years of age and are mostly located in the colon (cecum and ascending).The cause and mechanisms of GIA have yet to be completely understood. Small-bowel GIAs are often diagnosed in the setting of obscure gastrointestinal bleeding (OGIB). In some cases, GIAs are associated with aortic stenosis, Von Willebrand's disease, chronic renal disease, and liver disease...

BACKGROUND AND AIMS: The gastric mucosa is an endocrine organ that regulates satiation pathways by expression of orexigenic and anorexigenic hormones. Vertical sleeve gastrectomy (VSG) excludes gastric mucosa and reduces gastric volume. Our study aimed to investigate the independent effects of altering gastric mucosa on obesity and its related comorbidities. METHODS: Gastric mucosa devitalization (GMD) of 70% of the stomach was achieved by argon plasma coagulation in a high-fat diet rat model and was compared with VSG and sham surgery...

Vascular air embolism (VAE) is a rare, but potentially fatal complication of invasive medical or surgical procedures. It is a very rare complication of bronchoscopy and is most frequently reported with therapeutic bronchoscopy with Argon plasma coagulation (APC) or neodymium-doped yttrium aluminum garnet (Nd-YAG) laser. Despite being rare, as a result of its high chance of mortality and morbidity, it is imperative that physicians have high clinical suspicion to allow for early recognition and treatment. In this article, we provide a concise review of the incidence, pathophysiology, diagnosis management and outcomes of air embolism during bronchoscopy procedures...
