BACKGROUND: The sentinel lymph node (SLN) concept has been proposed to avoid unnecessary invasive LN dissection in surgery for esophageal cancer. This study evaluated a new macrophage-targeting fluorescent agent, indocyanine green-neomannosyl human serum albumin (ICG:MSA), for SLN mapping using a custom-made intraoperative color and fluorescence-merged imaging system (ICFIS) in porcine esophagus. METHODS: The LN targeting ability of ICG:MSA, indocyanine green-human serum albumin (ICG:HSA), and ICG was examined in vitro using the U937 differentiated monocyte cell line and in vivo in a mouse footpad model using fluorescence imaging...

Killian-Jamieson diverticulum (KJD) is a rare cervical esophageal abnormality. Transcervical approach has been the main treatment modality to prevent recurrent laryngeal nerve (RLN) injury. We presented two cases of patients confirmed with KJD and were managed successfully under rigid endoscope. The new technique and idea were described in detail. Under rigid laryngoscope, the septum between the true esophagus lumen and diverticulum can be exposed clearly. A microscope equipped with CO2 LASER system offered precise and focused point cutting energy to the septum...

Mostly ingested button batteries passed through the gastrointestinal tract without any adverse effects. But button battery can lead to hazardous complications including tracheoesophageal fistula (TEF), especially when the battery is impacted in the esophagus. Urgent esophagoscopic removal of the battery is essential in all cases. Once the TEF is identified, conservative management is the initial treatment of choice. Delayed primary repair can be tried if spontaneous closure does not occur. Here in we want to report a rare case of air leak syndrome, pneumo-pericardium secondary to the corrosive effect of a button battery and child recovered completely with conservative management...

OBJECTIVES/HYPOTHESIS: Rigid esophagoscopy is performed less frequently by resident trainees. Nonetheless, it remains important for certain indications, including foreign body extraction. This study describes the construction of a simulator and evaluates its utility in training residents. STUDY DESIGN: Simulator development, fabrication, and procedural evaluation of postgraduate trainees. METHODS: A simulator was developed and constructed in collaboration with a biomedical engineering team...

The era of bronchoscopy began with Gustav Killian in 1876 when he removed a pork bone from a farmer's airway, using an esophagoscope. Prompted by this accomplishment, Chevalier Jackson, an American otolaryngologist, laid the platform for the modern-day rigid bronchoscope in the early twentieth century. In 1967 Shigeto Ikeda revolutionized the field of bronchoscopy by his innovation of the fiberoptic bronchoscope. Today, bronchoscopy and interventional pulmonology have become an integral part of pulmonary medicine and an established subspecialty...

BACKGROUND: Despite the efficacy of molecular targeted therapy, surgical resection remains the only curative primary treatment for gastrointestinal stromal tumors (GISTs). However, in cases when the tumor originates from the thoracic esophagus, conventional transthoracic approach is highly invasive. METHODS: All procedures were performed with patients in a prone position through a double-lumen endotracheal tube for single-lung ventilation. First, to clarify the resection layer between the tumor and mucosal layer of the esophagus, a sodium hyaluronate solution colored with indigo carmine was injected into the submucosa via the esophagoscopic approach...

REVIEW
L Lampl
In order to achieve a minimal complication rate there is a need for a comprehensive strategy. This means in the first line preventive steps which include patient positioning, suitable approaches and access, an appropriately qualified surgical team as well as a carefully planned dissection and preparation. Furthermore, a supply of additional instrumentation, such as thrombectomy catheters, special vascular clamps and even extracorporeal membrane oxygenation (ECMO) and a heart-lung machine (HLM) in cases of centrally located lesions should be on stand-by...

BACKGROUND: The three commonly used free flaps for circumferential pharyngeal reconstruction after total pharyngo-laryngectomy are the radial forearm flap (RFF), the anterolateral thigh (ALT) flap, and the jejunum flap. This study was to objectively compare three different flaps for pharyngeal reconstruction during the past 10 years. Stricture and fistula were assessed using esophagogram and esophagoscopy. METHODS: Forty-five patients with pharyngeal reconstructions had esophagram and esophagoscopy done postoperatively to assess for strictures and fistulas...

Esophageal cancer, when detected at an early stage, has a very good probability of being eradicated by surgery or radiotherapy. However, less aggressive treatments also tend to provide high rates of cure without the side effects of radical surgery or radiotherapy. Among them, photodynamic therapy and endoscopic mucosal resection have been experienced as alternative techniques for mucosal ablation in patients with superficial squamous-cell carcinoma (SCC) of the esophagus, or high-grade dysplasia and early stage adenocarcinoma arising in Barrett's esophagus...

Introduction. Foreign bodies (FBs) in the aerodigestive tract are important causes of morbidity and mortality and pose diagnostic and therapeutic challenges. The best method of removal of an esophageal and tracheobronchial FB is endoscopic guided extraction. Objective. To present our experience of the removal of aerodigestive FBs in adult Ethiopian patients using rigid endoscopes. Methods. A hospital-based prospective study, at Tikur Anbessa Referral and Teaching Hospital, from January 2011 to December 2012 (over two years)...

OBJECTIVE: To highlight the contributions from the University of Chicago under the leadership of Dr David B. Skinner to the understanding of gastroesophageal reflux disease (GERD) and its complications. BACKGROUND: The invention of the esophagoscope confirmed that GERD was a premorbid condition. The medical world was divided between those who believed in a morphological lower esophageal sphincter (LES) and those who did not. Those who did not believe attempted to rearrange the anatomy of the foregut organs to stop reflux with minimal success...

AIM: To assess feasibility of unsedated esophagoscopy using a small-caliber disposable transnasal esophagoscopy and to compare its accuracy with standard endoscopy. METHODS: We prospectively included subjects who were referred for upper endoscopy. All subjects underwent transnasal endoscopy with E.G. Scan™. The disposable probe has a 3.6 mm gauge and at its distal end there is a 6 mm optical capsule, with a viewing angle of 125°. Patients underwent conventional endoscopy after the completion of E...

Benign esophageal tumors are rare; complete surgical resection is essential for the management of the submucosal tumors. Larger, symptomatic, or non-diagnostic lesions should be resected for both diagnostic and therapeutic indications. Video-assisted thoracic surgery has become a popular treatment in the field of thoracic surgery; however, thoracoscopic esophageal surgery may lead to an increase in operative complications. The effect and safety of thoracoscopic surgery for esophageal submucosal lesions were evaluated...

An unusual case of pancreatic arteriovenous malformation (P-AVM) combined with esophageal cancer is reported. A 59-year-old man was admitted with upper abdominal pain. Contrast-enhanced computed tomography showed numerous strongly enhanced abnormal vessels and a hypovascular lesion in the area of the pancreatic tail. Angiographic study of the celiac artery confirmed racemose vascular networks in the tail of the pancreas. Endoscopic retrograde pancreatography revealed narrowing and displacement of the main pancreatic duct in the tail of the pancreas...

OBJECTIVES: We used questionnaires to determine current practice patterns for esophagoscopy by otolaryngologists in the United States, with attention to foreign body management. METHODS: A 10-item questionnaire designed to determine the prevalence of flexible esophagoscopy use among otolaryngologists, with a particular focus on foreign body removal, was created and sent via e-mail to all members of the American Academy of Otolaryngology-Head and Neck Surgery. A second, 6-question survey to assess the level of resident training in flexible esophagoscopy was similarly created and sent to all directors of US otolaryngology residency programs...
