a) Fasting sG 1000 g/ml
b) Duodenotomy should be done in all cases
c) Diarrhoea most common symptom
d) SRS can localize 80% cases

Ans  )  c -

Duodenotomy detects 25% to 30% of tumors not seen on preoperative imaging.

Gastrin  levels higher than 1000 pg/mL are strongly suggestive of gastrinoma, provided that the patient demonstrated increased gastric acid  secretion ( gastric secretion ph should be less than 2) 

Most common is abdominal pain ( 75%) In 10% to 20% of patients, diarrhea is the only symptom ( Saby page 954) 

SRS should be performed because almost all gastrinomas express somatostatin receptors.
