This is a healthy patient wihout history of mental health illness or impaired cognitive issues.  Age and sex may suggest EoE or peptic stricture as possible etiology.

As there is no suspicion of intentional multiple foreing body ingestions, x ray would not be necessary. (Xray can be very useful to guide us when radiopaque objects have been ingested, to see whereabouts in the GI tract they may be lying)  As there is no subcutaneous emphysema or abdominal pain or guarding to suggest any perforation , a CT scan would not be needed.

As per the timing, ASGE  recommends emergent endoscopy for complete esophageal obstruction. ESGE   recommends emergent (preferably within 2 hours, but at the latest within 6 hours) gastroduodenoscopy for foreign bodies inducing complete esophageal obstruction, and for sharp-pointed objects or batteries in the esophagus. The cough and sialorrhaea suggest a complete obstruction.

They recommend urgent (within 24 hours)  for other esophageal foreign bodies without complete obstruction 

AGA-For patients with suspected non bony food bolus impaction without complications (eg,no evidence of perforation or respiratory distress),endoscopy may be performed without obtaining radiographs.

Glucagon 1mg iv can be given to induce esophageal relaxation and try and avoid urgent endoscopy, however it should not delay endoscopy and definetely we do not need 6-10 hours to see if it works.

Audit C score has 3 questions and if score is 5 or more, should prompt the full AUDIT of 10 questions.  Most questions ask about the past year alcohol habits. In a full AUDIT , any 15 or above represents high risk of alcohol dependence.

Number 3 is correct but not universal. A standard drink in US contains 14g, 10g in many EU countries and 8g in the UK. EASL advices to standardise to 10g (1 unit) but this is down to the individual countries. https://auditscreen.org/

If patient had HGD / Adenoca on a Barrett´s oesophagus, then the lesion is removed or ablated and afterwards the Barretts is fully ablated, we should perform regular gastroscopies for surveillance after Barretts eradication- yearly for 5 years and then at year 7 and 10-  Check the guidelines

If the reason for the ablation was only low grade dysplasia, then the surveillance can be 1,3 and 5 years and than surveillance can be stopped.
