BACKGROUND Mucosal ablation and endoscopic mucosal resection have been proposed as alternatives to surgical resection as therapy for intramucosal adenocarcinoma (IMC) of the esophagus. Acceptance of these alternative therapies requires an understanding of the clinical biology of IMC and the results of surgical resection modified for treatment of early disease. STUDY DESIGN Retrospective revie...

OBJECTIVES Locally advanced thymoma can often involve the phrenic nerve (PN) due to its location on the mediastinal pleura. However, en bloc resection including the PN may cause severe postoperative complications, especially in myasthenia gravis patients. The aim of the study was to determine whether a PN involved could be spared during thymoma resection. METHODS A retrospective study was con...

Inflammatory fibroid polyps are rare, non-neoplasic lesions that originate in the sub mucosa of the gastrointestinal tract. They were first described in the stomach by Vanek, in 1949. The aetiology of IFP is unknown. Surgical resection is the treatment of choice for this disease. The debate focused on the issue of primary en bloc resection of intussuscepted bowel versus initial reduction follow...

Giant colonic diverticulum is a rare complication of diverticulosis, which may present in the acute or chronic setting. Colonic resection and en bloc resection of the diverticulum are the favored management, however, conservative treatment remains an option that could be considered in asymptomatic patients with minimal symptoms.

OBJECTIVE The effects of the different surgical approaches (transhiatal esophagectomy and right-sided transthoracic esophagectomy) on perioperative cardiopulmonary function in the surgical treatment of esophageal carcinoma are discussed controversially and have not yet been evaluated. METHODS In a prospective randomized study including 32 patients, we investigated the effects of the surgical ...

Chondrosarcoma is a malignant tumor originating in cartilaginous cells. And there are only few reports of the case of chondrosarcoma in temporomandibular joint. We discuss a case of chondrosarcoma in temporomandibular joint in a 28-year-old man. Tumor was in contact with the dura, but en bloc resection was performed. After surgical resection of the tumor, face defect was reconstructed by rectus...

BACKGROUND/AIMS Endoscopic resection is the first-line treatment for rectal neuroendocrine tumors (NETs) measuring <1 cm and those between 1 and 2 cm in size. However, conventional endoscopic resection cannot achieve complete resection in all cases. We aimed to analyze clinical outcomes of precut endoscopic mucosal resection (EMR-P) used for the management of rectal NET. METHODS EMR-P was use...

BACKGROUND/AIMS To assess the therapeutic outcomes of endoscopic resection (ER) of early gastric cancer (EGC) with undifferentiated-type histology. METHODS Cases of ER of EGC with undifferentiated-type histology in the Korean endoscopic submucosal dissection (ESD) registry database were identified and reviewed. The immediate outcomes, including en bloc resection, complete resection, and curat...

INTRODUCTION Managing advanced head and neck cancer is often a difficult task, particularly when massive invasion of the carotid artery is present. However, en bloc resection can be a curative procedure, and reconstruction of the carotid artery limits the risk for stroke. The aim of this study was to describe the interest, indication, potential risks, and methods by which we carried out resecti...

PURPOSE Laser therapy provides an alternative option for treating non-muscle-invasive bladder cancer (NMIBC). However, the clinical evidence for potassium-titanyl-phosphate (KTP) laser en bloc resection is still limited. Here, we investigated the efficacy and safety of the 120-W front-firing KTP laser for the treatment of NMIBC. METHODS A total of 64 patients with NMIBC treated with either a ...
