It is well recognized that obesity is a big problem and it can induce large economic burden. Obesity affects about 40% people in the America alone and obesity also is the worldwide problem, with about 400 million obese adults. Moreover, another problem of obesity is the increasing prevalence of overweight children. Though bariatric surgery remains the gold treatment modality in the obesity treatment, endoluminal approaches may have the meaningful role for weight control. Endoscopists should have a role in the management of obesity because endoluminal therapies demonstrate their safety and efficacy over the coming years. Endoluminal therapies can be summarized by above methods: space occupying, malabsorption method, and reduction of gastric volume. In this review, we will introduce various restrictive endoscopic procedures in obesity treatment.

Subepithelial tumors (SETs) are occasionally found in the esophagus and stomach during upper endoscopy. Most SETs are asymptomatic and therefore clinically insignificant. However, SETs do have malignant potential, and therefore it is important to distinguish malignant from benign lesions. Among gastric SETs, gastrointestinal stromal cell tumors (GISTs) have malignant potentials that are related to tumor size; however, malignancy can occasionally be found in smaller lesions. Endoscopic ultrasound (EUS) can be used to diagnose GISTs preoperatively, although differential diagnosis on the basis of imaging alone is insufficient. However, when used in combination with EUS-guided fine needle aspiration, diagnostic accuracy increases, although the results can be quite variable. Therefore, we performed endoscopic biopsy of gastric SETs using the endoscopic submucosal dissection (ESD) technique. Our data indicate that deep biopsy via ESD is a safe modality of high diagnostic yield compared with EUS-guided fine needle aspiration in determining the histopathologic features of upper gastrointestinal (GI) SETs, relatively. In addition, pathologic confirmation can be more important than EUS finding. Diagnostic results improve clinical decision making on managing upper GI SETs. It can be recommended that this modality should be considered in upper GI SETs before determining whether tumors should undergo long-term monitoring or surgical resection.
