This report describes a new, minimally invasive procedure, posterior percutaneous endoscopic cervical diskectomy, performed with a unilateral biportal endoscopic approach. The procedure is used to treat cervical foraminal soft disk protrusion. This report also describes the short-term results with this procedure. In 2015, 14 patients underwent this new, minimally invasive procedure. The techniq...
inverted papillomas of the nose and paranasal sinuses are uncommon neoplasms, characterized by their tendency to occur and by their association with malignancy. in the past decade there has been a trend toward the use of endoscopic surgical techniques in the management of these tumors. this article presents the results of a prospective study of24 patients with inverted papilloma resected by the...
Drainage of pancreatic abscesses is required for effective control of sepsis. Endoscopic ultrasound (EUS)-guided endoscopic drainage is less invasive than surgery and prevents local complications related to percutaneous drainage. Endoscopic drainage with stent placement in the uncinate process of the pancreas is a technically difficult procedure. We report a case of pancreatic abscess treated b...
There has been booming interest in natural orifice transluminal surgery since it was first described. Several techniques first developed for the safe transluminal access now derive into independent endoscopic surgical procedures. In this paper, we describe a case treated by a novel procedure by submucosal tunnelling technique and provide a literature review of the rise of tunnel endoscopic surg...
right ventricular failure due to right coronary artery disease, right ventricular hypertrophy, stunning, abnormal septal motion, myocardial infarction, or non-homogeneous distribution of cardioplegia is an uncommon but serious complication of open heart surgery. we report a patient with severe right ventricular hypertrophy secondary to severe mitral valve stenosis and another patient with detac...
A 73-year-old woman underwent endoscopic mucosal resection for a 10-mm-diameter rectal polyp(Isp)within 5 cm of the anal verge in November 1995. Pathological examination showed that well-differentiated adenocarcinoma had invaded the submucosal layer with vascular invasion. Although secondary surgical treatment was recommended, the patient refused further treatment. Right-sided sciatica develope...
This paper presents a new registration algorithm of 2D color images and 3D geometric models for navigation system of surgical robot. A 2D-3D registration procedure is used to superimpose a tumor model on an endoscopic image precisely, and is therefore indispensable for the surgical navigation system. And thus, the performance of the 2D-3D registration procedure influences directly the usability...
OBJECTIVE To evaluate the short- and long-term success of the repair of congenital choanal atresia using the transnasal endoscopic approach with and without power instruments. DESIGN AND SETTING Retrospective case series in a tertiary care center. PATIENTS Fifteen patients with either unilateral or bilateral congenital choanal atresia were treated using the transnasal endoscopic approach. P...
Gastrointestinal subepithelial tumors (SETs) are generally found during endoscopy and their incidence has gradually increased. Although the indications for the endoscopic treatment of patients with SETs remain to be established, the feasibility and safety of endoscopic dissection, including the advantages of this method compared with surgical treatment, have been validated in many studies. The ...
Contour defects are common following primary craniofacial procedures including cranial vault remodeling, fronto-orbital and midface advancements, and complex posttraumatic reconstructions. When onlayed as fast-setting pastes, calcium phosphate cements (CPCs) have been used to effectively correct contour defects in open secondary reconstruction procedures. Here, we describe an endoscopic procedu...
