#4382 Sensitivity of endoscopic ultrasound in detecting small gastrointestinal neuroendocrine tumours

Introduction: Small gastrointestinal neuroendocrine tumours (GI-NETs) are often difficult to detect using conventional imaging modalities, leading to delayed diagnosis and suboptimal treatment outcomes. Endoscopic ultrasound (EUS) has emerged as a promising tool for the early detection and precise localisation of these tumours. However, its sensitivity in identifying small lesions remains to be thoroughly evaluated.

#4033 Routine early 68Ga-DOTATATE PET/CT has low diagnostic yield after resection of pancreatic neuroendocrine neoplasms

Introduction: Following resection of primary pancreatic neuroendocrine neoplasm (P-NEN), the reported median disease free survival is ≥4y. 68Ga-DOTATATE PET/CT (DOTA-PET) is widely used for restaging following surgical resection of P-NEN due to a higher sensitivity compared to cross-sectional imaging. We hypothesized that early DOTA-PET has a low yield in detecting recurrent/residual or distant disease in patients following curative-intent surgical resection of non-metastatic localised P-NEN.

#3174 Utility and timing of Technetium-99m-diethylene-triamine-penta-acetic acid measurement of glomerular filtration rate in patients undergoing peptide receptor radionuclide therapy

Introduction: Renal toxicity is a potential side effect of Lutetium-177 Peptide Receptor Radionuclide Therapy (177Lu-PRRT). Some centres use serial Technetium-99m-diethylene-triaminepentaacetic acid (99mTc-DTPA) glomerular filtration rate (GFR) measurements to detect early renal toxicity, but there is no consensus regarding the timing of serial scans nor its utility.

#2080 Linked Colour Imaging Increases the Diagnostic Yield of Type 1 Gastric Carcinoid

Introduction: Type 1 Gastric carcinoid tumours (GCTs) are the most common neuroendocrine tumours of the stomach. Endoscopic diagnosis of Type 1 GCTs remains a challenge. White light endoscopy (WLE) and Narrow Band Imaging (NBI) have failed to demonstrate reliable endoscopic signs of carcinoid.
