One Brand-new Maneuver to Place Nasoenteric Tube

Study Overview
=================
Brief Summary
-----------------
Naso-enteric tube feeding is necessary for certain patients. Many methods are used to place a naso-enteric tube, such as bed-side blind method, fluoroscopy method and guide-wire method. INvestigators aim to introduce a safe, non-expensive and fast method to insert a silicon naso-gastric (NG) tube into the small intestine.

Detailed Description
-----------------
Investigators tied a 1-cm surgical suture at the tip of a 16 French silicon NG tube (120 cm long, cost 5 US dollars). One conventional EGD (diameter 2.8 mm) biopsy forceps was inserted into the lumen as a strengthened stylet. Then investigators inserted a biopsy forceps (diameter 2.0 mm) and protruded a little out of the working channel of an ultrathin EGD scope (Fujinon EG 530 N, diameter 5.9 mm) to grasp the suture. The ultrathin EGD and NG tube were parallelly pushed into a selected nostril after adequate decongestive anesthesia (Epinephrine 0.3% + Lidocaine 5%) into the small intestine as deep as possible to the jejunum. Being placed to the small intestine as far as possible, the NG tube was released and the ultrathin EGD scope withdrew. When the scope was pulled backwards from the stomach, the shape/layout of a NG-tube could be simultaneously monitored and adjusted. At last, the EGD biopsy forceps (2.8 mm) inside the NG tube was removed. With this method, in real life, a plain film is not necessary to confirm the NG tube position. However, for study purpose, a KUB film was taken to check the NG tube position.
