Neuroendocrine tumors (NET) are a heterogeneous group of neoplasms that originate in tissues derived from the neural crest, whose characteristic feature is the expression of neuroendocrine markers and somatostatin receptors. Here, we present the case of a patient with a surgically intervened small bowel NET. Focal uptake was identified in the unresected mesentery in the scintigraphy of somatostatin receptors (99mTc-Tektrotyd). A second intervention was performed with intraoperative radio-guided detection with a gamma probe and a handheld SPECT. An intraoperative radioguided technique allowed the detection of a lesion that was confirmed by histology to be a lymph node metastasis of the NET and a nodule of NET in the anastomosis of the first surgical intervention.
