Abstract
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 mouth opening in 9, corrosive injury in 3, restricted
cervical spine movement in 2 and altered sensorium following
cerebrovascular accident in 2 patients. Transnasal
esophageal intubation failed in 1 patient each with oropharyngeal
malignancy and lipoma annularis coli. Wire-guided
naso-jejunal tube placement was done in 2 patients and
transnasal percutaneous endoscopic gastrostomy was done
in 1 patient. Two patients developed self-limiting epistaxis.
Ultrathin transnasal esophagogastroduodenoscope is a
useful tool in endoscopy units, particularly those dealing
with oncology patients. Inability to deliver endotherapy due to small diameter of the working channel is a limitation.
