BACKGROUND Esophageal granular cell tumor(eGCT)is a relatively rare,usually benign neoplasm of the neuroectoderm.It is derived from Schwann cells.Clinical symptoms of this disease are non-specific.However,the most common presenting symptom is dysphagia,which is mostly misdiagnosed as esophageal polyps under gastroscopy,yet it has a 2%chance of forming cancers.We report the case of a 52-year-old woman with solitary eGCT,then analysed retrospectivelyanalyze the clinical features and elucidate on the reduction of misdiagnosis and missed diagnosis.CASE SUMMARY A 52-year-old woman was diagnosed with“esophageal granulossoma”after esophagoscopy,which was mistaken for eGCT.CONCLUSION eGCT diagnosis depends on characteristic pathomorphologies and detection of the S-100 protein.Endoscopic mucosal resection is the preferred therapeutic method.

Endoscope-guided pneumatic dilation for treatment of esophageal achalasia

引用

World Journal of Gastroenterology 2010年第4期16卷 411-417页

Pneumatic dilation(PD) is considered to be the first line nonsurgical therapy for achalasia.The principle of the procedure is to weaken the lower esophageal sphincter by tearing its muscle fibers by generating radial force.The endoscope-guided procedure is done without fluoroscopic control.Clinicians usually use a lowcompliance balloon such as Rigiflex dilator to perform endoscope-guided PD for the treatment of esophageal achalasia.It has the advantage of determining mucosal injury during the dilation process,so that a repeat endoscopy is not needed to assess the mucosal tearing.Previous studies have shown that endoscope-guided PD is an efficient and safe nonsurgical therapy with results that compare well with other treatment modalities.Although the results may be promising,long-term follow-up is required in the near future.

A Coin and Something Else: A Rare Case Report

引用

International Journal of Otolaryngology and Head & Neck Surgery 2022年第1期11卷 12-17页

Foreign body ingestion in children is considered an emergency. The most common ingested foreign bodies are coins;however, the ingestion of disc batteries is on the rise requiring urgent rigid esophagoscopy. In the literature, multiple foreign body ingestion is very rare and only a few cases of multiple coins and multiple battery ingestion have been reported in the past. Herein, a case of simultaneous coin and battery ingestion requiring foreign bodies removal on two sequential endoscopies due to improper initial evaluation in a pediatric patient is reported which, to our knowledge, is the first reported case.

Accuracy of transnasal endoscopy with a disposable esophagoscope compared to conventional endoscopy

AIM: To assess feasibility of unsedated esophagoscopy using a small-caliber disposable transnasal esophagosco-py and to compare its accuracy with standard endoscopy.METHODS: We prospectively included subjects who were referred for upper endoscopy. All subjects un-derwent transnasal endoscopy with E.G. Scan^(TM). 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 endos-copy after the completion of E.G. Scan^(TM). We describe the findings detected by the E.G. Scan^(TM) and calculate the diagnostic accuracy, sensitivity, specificity, positive predictive value, negative predictive value and Kappa index for esophageal diagnosis.RESULTS: A total of 96 patients(54 women), mean age of 50.12 years(14 to 79), were evaluated. In all cases we were able to perform esophagoscopy with E.G.Scan^(TM). The average realization time was 5 min. A total of 58 alterations were detected in the esophagus, 49 gastric abnormalities and 13 duodenal abnormalities. We found that for esophageal varices, E.G. Scan^(TM) has sensitivity, specificity and diagnostic accuracy of 95%, 97% and 97%, respectively. Kappa coefficients were 0.32 for hiatal hernia, 0.409 for erosive gastroesopha-geal reflux disease, 0.617 for Barrett's esophagus, and 0.909 for esophageal varices.CONCLUSION: esophagoscopy with E.G. Scan? is a well-tolerated, fast and safe procedure. It has an ap-propriate diagnostic accuracy for esophageal varices when compared with conventional endoscopy.
