Stress Response Using Thin and Standard Size Endoscopy.
Sixty patients scheduled for upper diagnostic gastroscopy were randomised after written informed consent into three groups.
1. transnasal gastroscopy with thin endoscope
2. transoral with thin endoscope
3. standard size trans-oral endoscopy Stress response parameters (epinephrine, nor-epinephrine and cortisol, heartrate variability data and pulse oximetry data were monitored.
A substantial number of descriptive studies and clinical trials have made it evident that upper gastrointestinal endoscopy elicits cardiovascular and respiratory changes. Recent publications have indicated less marked cardiovascular changes when using thinner endoscopes or transnasal endoscopy .Hormonal stress response during upper gastrointestinal endoscopy has also been described, but never related to the different methods of upper gastrointestinal endoscopy. Furthermore the patient tolerance is markedly improved compared to the standard transoral route.
The aim of the present randomised study was to evaluate the ECG-, blood pressure- and pulse rate changes and the endocrine stress response (norepinephrine, epinephrine and cortisol) elicited by upper gastrointestinal endoscopy using a thin endoscope either transnasally or orally or a standard endoscope orally.
Method and material Sixty patients were included consecutively after written and informed consent and were all over 18 years. Patients receiving digitalis, ß-blocking agents or calcium antagonists were excluded, as well as patients receiving drugs for thyroid dysfunction or patients receiving steroids. Patients with known disease or trauma of the nasal cavity were not included.
Only intended diagnostic upper gastrointestinal endoscopies were included. The patients received standard medication during the endoscopy if required.
Immediately prior to the endoscopy each of the 60 patients chose an envelope with the allocation to one of three groups A) Endoscopy with a thin endoscope (4.5 mm Olympus prototype fiberendoscope) introduced transnasally (T group), B) Endoscopy with a thin endoscope (4.5 mm Olympus prototype fiberendoscope) introduced orally (O group) or C) Endoscopy with a standard gastroscope (6 mm Olympus GIF XV10) (S group). All patients received the same amount of a local anesthetic spray (Lidocaine 10 mg/dose, ASTRA Zeneca) (twice in each nostril and twice in the oropharynx, given by one of two particular persons to ensure application of comparable doses of local anesthetic).

Medical and Biotech [MESH] Definitions
Procedures of applying ENDOSCOPES for disease diagnosis and treatment. Endoscopy involves passing an optical instrument along either natural body pathways such as the digestive tract, or through keyhole incisions to examine the interior parts of the body. With advances in imaging, endoscope, and miniaturization of endosurgical equipment, surgery can be performed during endoscopy.
Endoscopic examination, therapy or surgery of the gastrointestinal tract.
Cardiac Imaging Techniques
Visualization of the heart structure and cardiac blood flow for diagnostic evaluation or to guide cardiac procedures via techniques including ENDOSCOPY (cardiac endoscopy, sometimes refered to as cardioscopy), RADIONUCLIDE IMAGING; MAGNETIC RESONANCE IMAGING; TOMOGRAPHY; or ULTRASONOGRAPHY.
Non-invasive, endoscopic imaging by use of VIDEO CAPSULE ENDOSCOPES to perform examination of the gastrointestinal tract, especially the small bowel.
Endoscopy, Digestive System
Endoscopic examination, therapy or surgery of the digestive tract.
It is unclear whether a topical pharyngeal anesthesia adds any benefit to the upper gastrointestinal endoscopy under a propofol sedation. We hypothesize that a topical pharyngeal anesthesi...
Gastric lavage is usually used for gastric preparation before endoscopy in patients with upper gastrointestinal bleeding. However, the benefit-risk balance of putting a nasogastric tube in...
The exploration of evocative symptoms of esophageal reflux disease or dyspepsia is based on a relatively invasive endoscopic examination, often badly tolerated, and which, in France, is ca...
Both upper gastrointestinal endoscopy and colonoscopy are recommended in men and post-menopausal women with iron deficiency anemia. Due to lack of data on the yield of these endoscopies in...
Two groups of patients were randomised into two groups of either transnasal gastroscopy or conventional type gastroscopy (n=98). The aim of the study was to evaluate the cardiorespiratory...
BACKGROUND: To assess the diagnostic effectiveness, cardiopulmonary safety, and patient comfort of transnasal endoscopy (TNE), compared with conventional endoscopy (CES) and sedated endoscopy (SES), a...
We performed a trial investigation of transnasal endoscopy for post-mortem examinations to assess its efficacy in superficial post-mortem examinations. Transnasal endoscopy proved capable of permittin...
BACKGROUND: The prevalence of eosinophilic esophagitis (EE) is increasing rapidly in Western countries. Several case series of EE have also been reported in Japan. However, the prevalence of EE in Jap...
ABSTRACT: BACKGROUND: Esophagogastroduodenoscopy is an often-used and safe diagnostic method in gastroenterology. Transnasal esophagogastroduodenoscopy is now an established addition to the endoscopic...
