Angiolipoma is a rare benign tumor that most commonly occurs in the extremities and trunk. Angiolipomas originating in the bronchial tree are extremely rare. To the best of our knowledge, only one such case, confined to the bronchus intermedius, has been reported to date. The present study describes the case of an asymptomatic 74-year-old man with a yellowish round mass incidentally discovered at the orifice of the right lower bronchus during a routine health check. The tumor originated from the membranous part of the right inferior bronchus...

Hany Shehab, Khaled Gawdat
BACKGROUND: Banded-gastric bypass is a highly effective bariatric procedure, yet the possibility of band erosion remains a significant drawback. Surgical removal of eroded bands may be associated with significant morbidity. In this study, we assess the efficacy and safety of a solely peroral endoscopic approach for the management of eroded bands in patients with a banded-gastric bypass. MATERIALS AND METHODS: Starting January 2012, all patients with banded-gastric bypass and an eroded band were subjected to an attempt at peroral endoscopic removal using endoscopic scissors and/or argon plasma coagulation (APC), regardless of the circumference of band eroding inside the lumen...

BACKGROUND: Anal canal high-grade squamous intraepithelial lesion (HSIL) is the precursor to anal cancer. Immunocompromised patients are at increased risk and disease is usually within 3 cm from the anal verge. High-resolution anoscopy (HRA) with an 8-cm anoscope is used to identify and guide cautery treatment of HSIL. PURPOSE: We report three patients with a long-term history of ulcerative colitis (UC) treated with systemic immunomodulators who developed proximally located rectal HSIL...

REVIEW
Stepan Suchanek, Tomas Grega, Miroslav Zavoral
The role of the surrounding equipment in endoscopic complications has not been published widely. However, an adequate understanding of the advantages and disadvantages of such devices might be helpful to avoid unnecessary problems during endoscopy. This is an overview of the basic principles, benefits and possible harms of electrical power units, medical gases and vital sign monitoring equipment. The aim of this review is to summarize current knowledge about the approach to the electrosurgical unit settings; periprocedural precautions, minimizing the risk of interference between endoscopic equipment and other electrical devices; the appropriate selection of instruments regarding the electrosurgical outcome and the role of carbon dioxide, argon plasma coagulation, pulse oximetry and capnography...

OBJECTIVES: Complete cytoreduction of ovarian cancer often requires excision or ablation of bowel serosa implants. Both argon beam coagulator (ABC) and thermal plasma energy (TPE) (PlasmaJet; PlasmaSurgical, Roswell, Ga) have been used to ablate bowel serosa implants. Our objective was to identify comparable power settings as well as determine the rate of bowel perforation, depth of thermal injury, and extent of inflammatory response with ABC versus TPE in a porcine model. MATERIALS AND METHODS: Nine pigs underwent vaporization of small bowel and colon serosa according to assigned treatment group (TPE vs ABC) and settings (ABC: 30, 50, and 70 W; TPE: Cut 10U, 20U, and 30U and Coagulation 10U, 20U, and 30U)...

Recurrent esophago-gastric junction adenocarcinoma is not a rare event and its correct management is still debated. Many approaches for the treatment of these patients exist, but only few studies compare the different techniques. Most of the studies are retrospectives series and describe the experiences of single institutions in the treatment of recurrent esophageal and esophago-gastric junction cancers. Nowadays surgery is still the main and only curative treatment. Other alternative palliative therapies could be endoscopic stent placement and balloon dilation, photodynamic therapy, thermal tumor ablation (laser photoablation and Argon plasma coagulation), radiation therapy and brachytherapy, and chemotherapy...

History and findings | A 56-year-old female with a gastric antral vascular ectasia (GAVE) suffered from recurrent episodes of upper gastrointestinal bleeding. Because of a history of a permanent atrial fibrillation (CHA2DS2-VASc score 3 points) an oral anticoagulation therapy with phenprocoumon was carried out which even worsened the bleeding frequency and intensity. A change of medication to low-molecular weight heparin did not lead to success. The frequent periods in hospital limited the patient's quality of life...

BACKGROUND & AIMS: Hereditary haemorrhagic telangiectasia is characterized by arterio-venous malformations (AVM). It frequently involves the liver without clinical symptoms, but may lead to biliary ischaemia, portal hypertension, or fatal high-output heart failure. The indication of liver transplantation is controversial. METHODS: Herein, we report the case of a 65-year-old female patient with a 'double Osler syndrome' consisting of hereditary haemorrhagic telangiectasia (HHT) and type I hereditary angioedema diagnosed at the age of 25 and 22 years respectively...

BACKGROUND AND AIM: Argon plasma coagulation (APC) is a safe alternative treatment for gastrointestinal neoplasms and precancerous lesions. However, the extent of thermal damage after APC is difficult to predict. We investigated the effects of APC on human stomach tissue. METHODS: APC was performed on 10 freshly resected human stomachs which were obtained after total gastrectomy. The effects on tissue were compared across power settings (40, 60, and 80 W), durations (5, 10, 15, 20, and 25 s), and between injection (submucosal injection of normal saline) and control (without injection) groups...

A 32-year-old woman presented with recurrent trachea-esophageal fistula. Although she had undergone open repair three times in her first year of life, a residual small leak was left. In the past 2 years she had experienced several lower respiratory tract infections and she had lost 5 kilograms in the past 2 months. Recent argon plasma coagulation cauterization and clipping of the fistula had failed, so an alternative technique with placement of an atrial septal occluder device was used to obliterate the fistula...

Portal hypertension commonly arises in the setting of advanced liver cirrhosis and is the consequence of increased resistance within the portal vasculature. Less commonly, left-sided noncirrhotic portal hypertension can develop in a patient secondary to isolated obstruction of the splenic vein. We present a rare case of left-sided portal hypertension and isolated gastric varices in a patient with large B-cell lymphoma, who was treated with splenic artery embolization. The patient is a 73-year-old male with no previous history of liver disease, who presented with coffee ground emesis and melena...

Gastric antral vascular ectasias (GAVE) have been increasingly recognized as an uncommon cause of chronic gastrointestinal bleeding and anemia, although their underlying pathogenesis is not completely well understood. Heterotopic gastric mucosa (HGM) has been reported to occur at various sites along the gastrointestinal tract and although relatively common, it is often asymptomatic. We report a case of a 60-year-old woman with a prior history of GAVE who developed melena and symptomatic anemia during her hospitalization following cardiac catheterization...

INTRODUCTION: Gastrointestinal bleeding is one of the most common indications for urgent endoscopy in the pediatric setting. The majority of these procedures are performed for control of variceal bleeding, with very few performed for non-variceal upper gastrointestinal (NVUGI) bleeding. The data on therapeutic endoscopy for NVUGI are very sparse. The aims of our study were to review our experience with NVUGI bleeding, describe technical aspects and outcomes of therapeutic endoscopy, and determine gastroenterology fellows' training opportunities according to the national training guidelines...
