AI Article Synopsis
- A case of early gastric cancer that mimicked a subepithelial lesion was diagnosed using endoscopic ultrasound-guided fine needle aspiration in a 55-year-old woman.
- Diagnostic imaging revealed multiple subepithelial lesions, and further evaluation suggested possible partial invasion of cancerous cells.
- The patient underwent surgery, which confirmed the diagnosis and showed no signs of recurrence after 10 months, highlighting the importance of EUS for early detection and intervention of similar conditions.
Article Abstract
We present a case of early gastric cancer resembling a subepithelial lesion (GCSEL) derived from the submucosal ectopic gastric glands (SEGGs), diagnosed using endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). A 55-year-old woman was referred to our hospital for the investigation of a subepithelial lesion (SEL). Contrast computed tomography and esophagogastroduodenoscopy revealed two SELs in the greater curvature of the fundus and the posterior wall of the upper body of the stomach. EUS revealed a hypoechoic lesion in the submucosa and suggested partial invasion into the muscularis propria of the greater curvature of the fundus, and an anechoic lesion in the submucosa of the posterior wall of the upper body. The different diagnosis for the SEL in the fundus was GCSEL, neuroendocrine tumor, malignant lymphoma, and gastric adenocarcinoma of fundic gland type. EUS-FNA findings suggested adenocarcinoma. The patient underwent a laparoscopic proximal gastrectomy. Pathological findings confirmed a differentiated tubular adenocarcinoma derived from the SEGG, which partially invaded into the submucosa of the surrounding gastric wall without lymphovascular invasion or lymph node metastasis. The patient has been recurrence-free after 10 months of follow-up. EUS should be performed for SELs followed by EUS-FNA for lesions, such as GCSEL, that require early intervention.

Free-Hand Endoscopic Full-Thickness Resection for Duodenal Subepithelial Lesions.
J Gastroenterol Hepatol

Endoscopy Center and Endoscopy Research Institute, Zhongshan Hospital, Fudan University, Shanghai, China.
Background And Aim: This work aims to evaluate the efficacy and safety of free-hand endoscopic full-thickness resection (EFTR) for duodenal subepithelial lesions (SELs).
Methods: We performed a retrospective review of 105 patients with duodenal SELs who underwent free-hand EFTR. Free-hand EFTR means no other devices (over-the-scope clip or full-thickness resection device) are required.

Introduction: Gastrointestinal stromal tumors (GIST), which occur anywhere in the gastrointestinal (GI) tract, typically occur in the stomach and small intestine but rarely in the duodenum. We present a case report wherein a descending duodenal GIST was treated with a limited, minimally invasive surgery after endoscopic nasobiliary drainage (ENBD) insertion.
Presentation Of Case: A 67-year-old woman visited our hospital with an incidentally discovered duodenal tumor.

Gastric polyps are commonly detected during upper gastrointestinal endoscopy. They are most often benign and rarely become malignant. Nevertheless, adequate knowledge, diagnostic modalities, and management strategies should be the endoscopist's readily available "weapons" to defeat the potentially malignant "enemies".

Granular cell tumors (GCTs) of the gastrointestinal tract are rare neoplasms often detected incidentally as subepithelial lesions during endoscopic examination. The occurrence of GCTs in the gastric cavity is even rarer. So far, there have been only four reports of multifocal gastric GCTs.

Background: Although clinicians frequently encounter incidentally detected gastroduodenal extrinsic compressive lesions (GDECLs) on upper gastrointestinal endoscopy (UGE), the optimal management approach for GDECLs has not been fully established. This study aimed to stratify and identify important factors associated with clinically significant GDECLs that require regular follow-up or further treatment.
Methods: Between June 2007 and December 2015, a total of 73 patients with suspected GDECLs on UGE at Kyung Hee University Hospital at Gangdong were identified and studied retrospectively.
