Feasibility of endoscopic resection and impact of endoscopic ultrasound-based surveillance on colorectal subepithelial tumors
Owing to the rising number of screening endoscopies and instrumental advances in endoscopic ultrasound (EUS), colorectal subepithelial tumors (SETs) are being increasingly detected. We aimed to determine the f...

Diagnostic performance of endoscopic ultrasonography-guided fine-needle biopsy in upper gastrointestinal subepithelial tumors measuring 2–5 cm in size
Subepithelial tumors (SETs) in the upper gastrointestinal (GI) tract are frequently discovered during upper endoscopy, and their management is determined based on size and histopathological diagnosis. We aimed...

Association between mucin phenotype and lesion border detection using acetic acid–indigo carmine chromoendoscopy in early gastric cancers
For successful treatment of early gastric cancers (EGCs), it is crucial to define the horizontal border of the lesion with high accuracy. Acetic acid–indigo carmine (AI) chromoendoscopy has been used to determ...

Long-term outcomes of endoscopic resection followed by additional surgery after non-curative resection in undifferentiated-type early gastric cancer: a nationwide multi-center study
Undifferentiated-type early gastric cancer (UD EGC) shows lower curative resection rates after endoscopic submucosal dissection (ESD). Additional surgery is recommended after non-curative resection. We evaluat...

Prediction model for curative endoscopic submucosal dissection of undifferentiated-type early gastric cancer
Endoscopic submucosal dissection (ESD) is an effective treatment for early gastric cancer (EGC); however, its curative resection rate is low for undifferentiated-type EGC. We developed and externally validated...

Long-term outcomes of endoscopically resected laterally spreading tumors with a positive histological lateral margin
With advances in diagnostic endoscopy, the incidence of superficial colorectal tumors, including laterally spreading tumors (LSTs), has increased. However, little is known about the long-term results of LSTs w...

Tumor localization using radio-frequency identification clip marker: experimental results of an ex vivo porcine model
With the widespread use of minimally invasive surgery, tumor detection is becoming more difficult. We present the experimental results of a radio-frequency identification (RFID) lesion detection system in an e...

Endoscopic submucosal dissection for undifferentiated-type early gastric cancer: short- and long-term outcomes
Application of endoscopic submucosal dissection (ESD) for undifferentiated-type early gastric cancers (EGCs) remains controversial owing to limited data regarding long-term outcomes. We aimed to evaluate the f...

Endoscopic submucosal dissection for esophagogastric junction tumors: a single-center experience
Surgical resection for esophagogastric junction (EGJ) tumors is more aggressive and worsens the quality of life of the patients and leads to poor prognosis even after surgery compared with tumors in other site...

Clinicopathologic features of early gastric carcinoma with lymphoid stroma and feasibility of endoscopic submucosal dissection
Gastric carcinoma with lymphoid stroma (GCLS) is a rare disease known to have unique features and a favorable prognosis. This study aimed to determine the clinicopathologic features of early GCLS (EGCLS) and d...

Risk factors for local recurrence in patients with positive lateral resection margins after endoscopic submucosal dissection for early gastric cancer
With the widespread use of endoscopic submucosal dissection (ESD) in patients with early gastric cancer (EGC), the number of cases with incomplete resection due to positive lateral resection margins (LM+) is i...

Endoscopic resection of gastrointestinal lipomas: a single-center experience
Gastrointestinal (GI) lipomas are benign, slow-growing subepithelial tumors. Most lipomas are detected incidentally at endoscopy, but they can cause GI bleeding, abdominal pain, intestinal obstruction, and int...

Long-term outcomes of endoscopic submucosal dissection for early gastric cancer: a single-center experience
In Korea, endoscopic submucosal dissection (ESD) has been widely accepted for the treatment of early gastric cancers (EGCs). However, the understanding of the long-term clinical outcome of ESD for EGC remains ...
