Transnasal endoscopy for direct visual control of esophageal stent placement without fluoroscopy.

Placement of self-expanding metal stents (SEMSs) is a well-established treatment for esophageal stenosis and postoperative anastomotic leaks. Conventional endoscopic procedures for SEMS placement require fluoroscopic guidance, but transnasal endoscopy (TNE) with ultraslim endoscopes may allow precise stent release under direct visual control without the need for fluoroscopy. This prospectively collected data investigated the feasibility and safety of TNE-guided SEMS placement without fluoroscopy.

[Extensive squamous papillomatosis of the oesophagus with malignant transformation of squamous epithelium].

While small solitary oesophageal papillomas are uncommon findings that are occasionally identified on routine upper endoscopies, extensive oesophageal papillomatosis is an extremely rare condition with only 9 cases reported in the English literature. We report the case of a 72-year-old woman who was referred for progressive dysphagia for solid food and clinical signs for a reflux disease. Upper endoscopy demonstrated bizarre villous alterations of the mucosa covering the oesophagus subtotally and a suspicious area within these alterations.

[Secondary aorto-enteral fistula as a cause of acute recurrent gastrointestinal bleeding, 20 years after living kidney donation].

Aorto-enteral fistulas (AEF) are a rare but life-threatening cause of acute gastrointestinal bleeding. Clinically, they can appear through massive haematochezia and haematemesis or as intermittent occult intestinal bleeding. The diagnostic procedure using endoscopy is often difficult but can contribute to making the correct diagnosis.

Endoscopic closure of postoperative esophageal leaks with a novel over-the-scope clip system.

Management of esophageal anastomotic leaks is associated with high morbidity and mortality and remains an interdisciplinary challenge. We describe the first two cases of endoscopic closure of postoperative leaks following gastrectomy and primary repair after spontaneous acute esophageal perforation, using the over-the-scope clip (OTSC) system (Ovesco Endoscopy GmbH, Tübingen, Germany). Both leaks were successfully sealed with one clip.
