Esophageal schwannoma is a very rare submucosal tumor. We report successful management of esophageal schwannoma in a 41-year-old man who complained of progressively worsening dysphagia. A huge submucosal tumor was found via endoscopy and a chest computed tomography scan. Esophagectomy was performed with no post-operative complications. Post-operative immunohistochemistry staining showed a positive result for S-100 and negative results for c-kit and CD34. The post-operative mild dysphagia persisted, and the follow-up endoscopic findings revealed anastomosis site stenosis. Approximately 2 months later, we performed endoscopic balloon dilatation. We report herein a case of esophageal schwannoma with reviews.

Background/Aims: Endoscopic vacuum therapy (EVT) can heal a variety of defects within the gastrointestinal (GI) tract via applying negative pressure, which reduces the defect size, aspirates the infected fluid, and promotes granulation tissue. Here we present our experience with EVT as it relates to both spontaneous and iatrogenic upper GI tract perforations, leaks, and fistulas. Methods: This retrospective study was conducted at four large hospital centers. All patients who underwent EVT between June 2018 and March 2021 were included. Data on multiple variables were collected, including demographics, defect size and location, number and intervals of EVT exchanges, technical success, and hospital length of stay. Student t-test and the chi-squared test were used to analyze the data. Results: Twenty patients underwent EVT. The most common defect cause was spontaneous esophageal perforation (50%). The most common defect location was the distal esophagus (55%). The success rate was 80%. Seven patients were treated with EVT as the primary closure method. The mean number of exchanges was five with a mean interval of 4.3 days between exchanges. The mean length of hospital stay was 55.8 days. Conclusions: EVT is a safe and effective initial management option for esophageal leaks and perforations.

The laryngeal foreign bodies are not common among the foreign bodies in the air and food passage, however, it would cause fatal airway obstruction without performing immediate endoscopic removal or emergency tracheostomy procedure. It is our intent to report three cases of laryngeal foreign bodies, and to discuss diagnostic procedures, preventive measures and management of this problems.

Foreign bodies of the upper aerodigestive tract in the pediatric population are a common occurrence. However, despite significant advances in prevention, first aid and endoscopic technology, they remain a diagnostic and therapeutic challenge. Early diagnosis is the key to successful and uncomplicated management of these accidents. An orderly and systematic approach to these patients including a careful history, physical exam and radiographic studies is detailed in this review.

Primary duodenal follicular lymphoma is rare and presents as multiple, small polyp-like lesions on endoscopy. If this lesion is suspected, an endoscopic biopsy is crucial for diagnosis. A watchful wait would be appropriate management as it has a fairly indolent clinical course. Herein, we present a rare case of primary duodenal follicular lymphoma.

Barrett's esophagus is associated with an increased risk of adenocarcinoma. Thorough screening during endoscopic surveillance is crucial to improve patient prognosis. Detecting and characterizing dysplastic or neoplastic Barrett's esophagus during routine endoscopy are challenging, even for expert endoscopists. Artificial intelligence-based clinical decision support systems have been developed to provide additional assistance to physicians performing diagnostic and therapeutic gastrointestinal endoscopy. In this article, we review the current role of artificial intelligence in the management of Barrett's esophagus and elaborate on potential artificial intelligence in the future.

We report on the case of a 52-year-old female who presented with a stress fracture after undergoing an endoscopic resection of the lesser trochanter in ischiofemoral impingement, which was resistant to maximal conservative treatment. To the best of our knowledge, this complication has not been previously described. Non-weight-bearing and intravenous alendronic acid were prescribed for management. No additional surgery was required. The patient was pain free with the ability to perform sports on the same level as before and had no complaints.

Cystitis and proctitis are defined as inflammation of bladder and rectum respectively. Haemorrhagic cystitis is the most severe clinical manifestation of radiation and chemical cystitis. Radiation proctitis and cystitis are major complications following radiotherapy. Prevention of radiation-induced haemorrhagic cystitis has been investigated using various oral agents with minimal benefit. Bladder irrigation remains the most frequently adopted modality followed by intra-vesical instillation of alum or formalin. In intractable cases, surgical intervention is required in the form of diversion ureterostomy or cystectomy. Proctitis is more common in even low dose ranges but is self-limiting and improves on treatment interruption. However, treatment of radiation proctitis is broadly non-invasive or invasive. Non-invasive treatment consists of non-steroid anti-inflammatory drugs (NSAIDs), anti-oxidants, sucralfate, short chain fatty acids and hyperbaric oxygen. Invasive treatment consists of ablative procedures like formalin application, endoscopic YAG laser coagulation or argon plasma coagulation and surgery as a last resort.

Purpose: The management of frontal sinus fractures and frontal sinus outflow tract (=FSOT) injuries is controversial. Traditional treatments include frontal sinus obliteration with a variety of material grafts, which all employ complicated algorithms for treatment planning. A simplified algorithm aiming for frontal sinus ventilation, however, can be achieved through the advanced technology of image guided endoscopic surgery and instruments. The authors explain this simplified treatment algorithm of frontal sinus fractures. Methods: The authors reviewed articles on the management of frontal sinus fractures. Results: Complicated treatment planning algorithms of frontal sinus fractures aiming for obliteration were replaced with a simplified algorithm aiming for ventilation of the frontal sinus. Conclusion: The authors suggest that a simplified algorithm can replace the complicated algorithms in selective cases.

Vocal fold leukoplakia poses a challenge to otolaryngologists due to its various spectrum of pathologic diagnosis. The degree of dysplasia is associated with malignancy risk and the new 2017 WHO classification system changed from the 3-tier system to a 2-tier system consisting of low and high grades. Infections including candidiasis, cryptococcosis, and tuberculosis should also be included in the differential diagnosis. Efforts have been made to evaluate risks using endoscopic technologies such as narrow band imaging, and surgery is essential for histopathological diagnosis. Regarding management, it is important to make an accurate diagnosis and find a balance between oncologic safety and functional outcome.
