Article Abstract
For an esophageal submucosal mass suspicious of granular cell tumor (GCT) based on gross appearance and endoscopic ultrasound findings, a sufficient number of biopsy specimens is required for a definite diagnosis using immunohistochemical examination. When the specimen obtained by forceps biopsy is insufficient, endoscopic ultrasound-fine needle aspiration (EUS-FNA) is believed to be an useful alternative. However, it may be difficult to obtain an adequate amount of tumor material using EUS-FNA. Mucosal incision-assisted biopsy (MIAB) is a simple method that can collect larger amounts of specimens. This procedure is helpful for physicians who encounter the problem of obtaining an adequate amount of biopsy material from esophageal tumors suspicious for GCT. We present a case of esophageal GCT that was successfully diagnosed through MIAB.

A Prenatally Diagnosed Rare Vascular Ring Formed by Left Aortic Arch and Right Ductus Arteriosus.
JACC Case Rep
September 2025
Department of Obstetrics and Gynecology, Juntendo University Faculty of Medicine, Tokyo, Japan.
Background: A vascular ring arises during the development of the fetal arches and is often associated with a double aortic arch or right-sided aorta, an aberrant left subclavian artery with a posterior esophageal component, and a left-sided ductus arteriosus.
Case Summary: This is a rare vascular ring formed by a left aortic arch, aberrant right subclavian artery, and right ductus arteriosus that was diagnosed prenatally by fetal echocardiography. The 3-vessels and trachea (3VT) view with 2-dimensional and color Doppler sweeps were helpful in defining the vascular pathology.

This article aims to explore the clinical characteristics and corresponding nursing points of elderly patients with massive hiatal hernia. A case study of an elderly patient with massive hiatal hernia and severe cardiopulmonary disease was reviewed, along with relevant literature. Nursing points are the following: multidisciplinary team to estimate surgical risks and develop individualized pre-rehabilitation management strategies; assessment and intervention for thrombosis and bleeding risks; postoperative hemodynamic monitoring and precise fluid management; dynamic observation of inflammatory indicators and infection prevention and care; and follow-up visits and health guidance after discharge.

Initial management typically includes thoracic endovascular aortic repair (TEVAR) or aortic graft replacement to achieve hemostasis, followed by esophagectomy with aortic graft replacement and greater omentum wrapping to eliminate the source of infection. We report a case of successful endoscopic closure of a chronic esophageal fistula secondary to AEF.

Leiomyomas are the most common benign mesenchymal tumors of the esophagus, and they account for nearly two-thirds of benign esophageal neoplasms. The leiomyomas of the esophagus present with numerous nonspecific symptoms and signs, including dysphagia, shortness of breath, anorexia, weight loss, chronic cough, and bowel obstruction. The patient in this case report presented with moderate to severe right upper quadrant pain and mild dysphagia, which initially prompted evaluation for hepatobiliary pathology.

Introduction: Tracheoesophageal fistula (TEF), often occurring with esophageal atresia (EA), presents significant respiratory challenges in neonates. Neither the effect of EA/TEF, nor the effect of post-surgical complications such as tracheomalacia, on respiratory effort has been previously quantified. This study calculates the tracheal resistive component of work of breathing (TR-WOB) to quantify breathing effort pre- and post-surgical repair of EA/TEF.
