BACKGROUND/AIMS The rate of diagnosis of gastric adenoma has increased because esophagogastroduodenoscopy is being performed at an increasingly greater frequency. However, there are no treatment guidelines for low-grade dysplasia (LGD). To determine the appropriate treatment for LGD, we evaluated the risk factors associated with the categorical upgrade from LGD to high grade dysplasia (HGD)/ear...

Objectives We present a case of olfactory preservation after a unilateral transcribriform transethmoidal endoscopic resection of esthesioneuroblastoma. We also discuss the oncologic results of endoscopic and transcranial approaches and describe the potential benefits and limitations of an endoscopic approach. Setting Single academic medical center. Participant and Design The clinical course of ...

BACKGROUND/AIMS In endoscopic submucosal dissection (ESD) training, only a flat target lesion can usually be simulated in the normal mucosa. This study aimed to evaluate the feasibility of simulated targets in the stomachs of live pigs for complete training. METHODS Six trained endoscopists with hands-on experience with ex vivo, isolated pig stomachs were enrolled in this pilot study. An endo...

BACKGROUND Endoscopic submucosal dissection (ESD) is accepted as a minimally invasive treatment for early gastric cancer, however, it is not widely used in the colorectum because of its technical difficulty. OBJECTIVE To determine the feasibility of using ESD for treating large superficial colorectal tumors. PATIENTS A total of 400 consecutive patients were treated by ESD for 405 lesions at...

Aims. To retrospectively analyze the clinical outcomes for a large number of endoscopic submucosal dissections (ESDs) in early esophageal squamous cell neoplasms (ESCNs) at the First Affiliated Hospital of Nanjing Medical University. Patients and Methods. From January 2010 to February 2014, 296 patients (mean age 61.4 years, range 31-85 years; 202 men) with 307 early ESCNs (79 intramucosal inva...

INTRODUCTION Hydatid liver cysts can rupture into neighboring structures in 15-60% of patients, and most often involves the bile duct, the bronchi, and the peritoneal/pleural cavities. Rarely, chest or abdominal wall involvement occurs that are challenging to manage. This case report and literature review describes the management of patients with chest wall and rib invasion. PRESENTATION OF C...

BACKGROUND/AIMS Endoscopic submucosal dissection (ESD) for tumors occurring in the remnant stomach is technically difficult to perform because of limited working space and severe fibrosis and staples present around the suture line. We aimed to elucidate the feasibility and clinical outcomes of performing ESD for tumors in the remnant stomach. METHODS Between December 2007 and January 2013, 18...

Endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR) techniques have reduced the need for surgery in early esophageal and gastric cancers and thus has lessened morbidity and mortality in these diseases. ESD is a relatively new technique in western countries and requires rigorous training to reproduce the proficiency of Asian countries, such as Korea and Japan, which hav...

mors, also called carcinoid tumors, in the duodenum are rare. The therapeutic approach is highly dependent on both tumor size and depth of invasion; for tumors smaller than 1.0 cm and without penetration of the muscularis propria, endoscopic resection is considered as the method of choice [1]. A 65-year-old woman with a histologically proven neuroendocrine tumor in the duodenal bulb was referre...

RATIONALE Three-dimensional (3D) printed templates can be designed to match an individual's anatomy, allowing surgeons to refine preoperative planning. In addition, the use of computer navigation (NAV) is gaining popularity to improve surgical accuracy in the resection of pelvic tumors. However, its use in combination with 3D printing to assist complex pelvic tumor resection has not been report...
