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...

The aim of this study was to analyze the location, the cause and treatment of iatrogenic gastrointestinal perforations following therapeutic endoscopic procedures. Perforation occurred in 12 patients out of 3,389, giving cases occurred intraoperatively or postoperatively. Among them, 6 cases were closed by titanium clipping and 1 case by purse string suture. In another case after cap-assisted endoscopic mucosal resection (EMRC), attempted titanium clipping failed, emergency surgery had to be performed. One each case, after Argon plasma coagulation (APC) and case after endoscopic piecemeal mucosal resection (EPMR), recovered well spontaneously...

A 47-year-old patient presented from outside the hospital for evaluation of iron deficiency anemia (IDA). The endoscopic workup suggested a gastric antral subepithelial lesion with an overlying arteriovenous malformation (AVM). Endoscopic ultrasound (EUS) revealed the lesion to be a lipoma. Given the patient's anemia and blood transfusion requirements, the AVM was treated with argon plasma coagulation (APC). During this treatment, desiccation of fat was noted with a significant decrease in the size of the subepithelial lesion (the gastric lipoma)...

Gastric adenoma (dysplasia) is a precancerous lesion. Therefore, managements of gastric adenomas are important for preventing the development of gastric cancers and for detecting gastric cancers at earlier stages. The Vienna classification divides gastric adenomas into two categories: high-grade dysplasia and low-grade dysplasia. Generally, endoscopic resection is performed for adenoma with high-grade dysplasia due to the coexistence of carcinoma and the potential of progression to carcinomas. However, the treatments of adenoma with low-grade dysplasia remain controversial...

OBJECTIVES: Symptomatic cervical heterotopic gastric mucosa also addressed as cervical inlet patch (CIP) may present in varying shapes and causes symptoms of laryngopharyngeal reflux (LPR) like globus sensations, hoarseness and chronic cough. Unfortunately, argon plasma coagulation, standard treatment of small symptomatic CIP, is limited in large CIP mainly due to concerns of stricture formation. Therefore, we aimed to investigate radiofrequency ablation (RFA), a novel minimal-invasive ablation method, in the treatment of CIP focusing on large symptomatic patches...

Patients with Barrett's esophagus (BE)/columnar lined esophagus (CLE) and adenocarcinoma are increasing, in whom 0.61% BE/CLE would develop to adenocarcinoma. The prognosis of esophageal cancer is related to the tumor stage at diagnosis. To standardize the screening, diagnosis and therapy of BE and adenocarcinoma in China, 31 digestive diseases and digestive endoscopy experts and digestive histologists drafted the consensus on the basis of clinical experience and references. The consensus defined BE as a complication of gastroesophageal reflux disease...

The current standard-of-care treatment for patients with limited-stage small-cell lung cancer (SCLC) is concurrent chemoradiotherapy for local and systemic control. However, standard-of-care treatment strategies have not been established for those with limited-stage SCLC who have a history of thoracic radiotherapy due to concerns with complications associated with radiation overdose. A 37-year-old male developed an aspergilloma in the postoperative left thoracic space after he was treated with concurrent chemoradiotherapy for mediastinal type lung adenocarcionoma and subsequent left upper lobectomy for heterochronous dual adenocarcinoma...

Benign anastomotic strictures can occur in up to 22% of patients who undergo colonic or rectal resection. Traditionally, surgery was the preferred method of treatment, but, over time, endoscopic techniques, such as balloon dilation, have become the preferred modality. However, a high stricture recurrence rate of up to 18-20% and the increased risk of perforation due to uncontrolled stretching are its major drawbacks. Endoscopic electrocautery incision (EECI) allows for controlled mucosal incision in predetermined locations of stricture...

Fibroepithelial polyps are benign lesions, frequently found in the skin and genitourinary tract. Airway involvement is rare, and few case reports have been published. Our patient was a 79 y.o. male smoker, who was referred to us with a 3-month history of dry cough. At physical examination, the patient looked well, but a chest CT showed a 6-mm polyp lesion in his trachea. A flexible bronchoscopy confirmed this lesion, and forceps biopsies were performed. Argon plasma coagulation was used to completely resect and treat the lesion...

Non-thermal plasma has been used in many medical applications, including treatment of living cells, blood coagulation, wound healing, and sterilization. The process uses an environmentally friendly gas (e.g., argon, helium, oxygen, nitrogen, or hydrogen) to destroy bacteria cells with no serious adverse effect on humans or animals. However, information on the effect of argon plasma on blow fly eggs is lacking. In this study, we explored the ability of cold argon plasma to destroy the eggs of the Australian sheep blow fly, Lucilia cuprina (Wiedemann, 1830); its larvae are a myiasis-producing agent in both human and animals...

Gastric antral vascular ectasia (GAVE), also known as "watermelon stomach", is an uncommon condition, which can cause gastrointestinal bleeding due to rupture of blood vessels that line the stomach. The pathogenesis of GAVE remains unclear; however it is thought that hemodynamic changes, mechanical stress, and autoimmune factors all have a part to play. A range of conditions are also commonly associated with the syndrome, such as portal hypertensive gastropathy, liver cirrhosis, and autoimmune disorders. Less commonly, chronic renal failure, cardiac diseases, and bone marrow transplantation have coexisted with GAVE...

Central airway obstructive infections (CAOI) are challenging medical conditions that may represent an advanced and complicated process of ongoing infections. The epidemiology of CAOI is unknown as well as the pathophysiology and the mechanism of development. This is due to sparse data in the literature that consists mainly of case reports and retrospective case series. CAOI can be caused by fungal, bacterial, parasitic and viral infections. Most patients with CAOI can be diagnosed clinically and with chest imaging, which demonstrate obstruction of the central airways...

Gastric hemangioma in the neonatal period is a very rare cause of upper gastrointestinal bleeding. We present a case of hemangioma limited to the gastric cavity in a 10-day-old infant. A huge, erythematous mass with bleeding was observed on the lesser curvature side of the upper part of the stomach. Surgical resection was ruled out because the location of the lesion was too close to the gastroesophageal junction. Medical treatment with intravenous H2 blockers, octreotide, packed red blood cell infusions, local epinephrine injection at the lesion site, application of hemoclip, and gel-form embolization of the left gastric artery did not significantly alter the transfusion requirement...

Background/Aims: Colonoscopy can detect precancerous lesions, which can subsequently be removed and reduce incidences of and mortality from colorectal cancer (CRC). However, recently published data have highlighted a significant rate of CRC in patients who previously underwent colonoscopy. Among many reasons, incomplete resection has been considered as a significant contributor. However, to date, there have only been a few studies regarding incompletely resected polyps, especially advanced colorectal adenoma (ACA)...
