Transnasal Percutaneous Endoscopic
نویسندگان
چکیده
Transoral percutaneous endoscopic gas− trostomy (PEG) is not possible in some pa− tients due to difficulty in opening the mouth (e.g., in patients with head and neck cancers, oral submucous fibrosis, dental misalignment, and intermaxillary fixation). Transnasal endoscopy has been used for diagnostic upper gastrointestinal endoscopy and for placement of enteral feeding tubes [1, 2]. However, the small diameter of the accessory channel in transnasal instruments (2 mm) limits their use for therapeutic interventions [3]. A study of transnasal percutaneous endoscopic gastrostomy (TN−PEG) using pediatric scopes (with an outer diameter of 7.9 mm) reported failure of the method in three of six patients [4]. TN−PEG using standard−diameter endoscopes has been reported [5].

Prospective randomized comparative study of hemodynamic changes between ultrathin transnasal and conventional transoral esophagogastroduodenoscopy in percutaneous endoscopic gastrostomy placement with modified introducer method under sedation.
AIM Percutaneous Endoscopic Gastrostomy (PEG) placement is a useful but invasive method. Recently, the hemodynamic change of ultrathin transnasal esophagogastroduodenoscopy (transnasal EGD) was reported as less than that of conventional transoral EGD (transoral EGD). This study compared hemodynamic changes between transnasal EGD and transoral EGD in the setting of PEG placement using a modified...
متن کاملTransgastrostomal Observation and Management Using an Ultrathin Endoscope After Percutaneous Endoscopic Gastrostomy
Recent developments have made ultrathin endoscopes available for routine esophagogastroduodenoscopy and also for unsedated transnasal observation (Shaker, 1994). Transnasal endoscopy is known to be less of a burden for patients (more tolerable) than transoral endoscopy and has benefits including fewer effects on respiratory and cardiovascular status and reduced recovery time after the procedure...
متن کاملTransgastric Diversion of Transnasal Long Tube Placement Using a Percutaneous Endoscopic Gastrostomy Site in a Patient with Bowel Obstruction and Massive Ascites due to Ovarian Carcinoma
The course of patients with advanced ovarian carcinoma is often complicated by bowel obstruction and/or massive ascites. A transnasal long tube may be placed to relieve bowel obstruction, but produces nasal discomfort and pain. Recently, the effectiveness of percutaneous endoscopic gastrostomy (PEG) tube placement for malignant bowel obstruction due to ovarian carcinoma has been reported, but n...
متن کاملRole of ultrathin transnasal esophagogastroduodenoscopy: experience with 50 patients.
Conventional gastroscopes have a diameter of 8.8-12 mm; ultrathin endoscopes have an outer diameter of 5.3-5.9 mm. We share our experience with 50 patients who underwent transnasal esophagogastroduodenoscopy using an ultrathin endoscope. The indications included endoscopyassisted nasogastric tube placement in 25 patients, tight lesions not negotiable with conventional endoscope in 9, restricted...
متن کاملPull method percutaneous endoscopic gastrostomy using transnasal ultrathin endoscopy in head and neck cancer.
Dysphagia due to tumor ulcers and stomatitis induced by chemoradiotherapy is painful; it is therefore crucial and urgent to establish a surgical enteral feeding route in patients with head and neck cancer to avoid malnutrition and improve treatment compliance [1]. However, common trismus caused by surgical resection, reconstruction, and, mostly, radiation fibrosis often compromise flexible endo...
