**5.10 Gallium-68 dotatate PET/CT scan**

Gallium-68 dotatate PET/CT scan is now considered as the best scan for detecting SBNET as 70–90% of them have somatostatin receptors. It has much better imaging quality and can detect more lesions than Octreoscan [37]. But it does not replace CTE or MRE for those SBNET which are not somatostatin receptor positive.

### **5.11 Intraoperative enteroscopy**

Intraoperative enteroscopy is done in the operating room when other modalities of investigations fail to detect the source of bleeding. The scope is introduced through the mouth or through an enterotomy, and whole small bowel can be evaluated. It is diagnostic as well as therapeutic in achieving hemostasis in about 70% of cases.
