Multivisceral Transplantation and Vascularised Sentinel Forearm Flap for a Metastatic Gut-Derived Neuroendocrine Tumour: Follow-up Abstract #1558

Introduction: We previously reported the first documented case of a novel approach in a patient with extensive mesenteric metastases from a small bowel (SB) NET: this combined multivisceral transplantation (MVT) and a vascularised sentinel forearm flap (VSFF) from the same donor.
Aim(s): We re-present this case after prolonged follow-up.
Materials and methods: A male patient was diagnosed with a well-differentiated Grade 1 (Ki67 <1%) NET when aged 44. Initial biochemistry was: chromogranin A 395pmol/L (normal <60), chromogranin B 349pmol/L (normal <150), 24hr urinary 5-HIAA 643 ┬Ámol/L (normal <40). Pre-operative 68-Ga DOTATATE PET/CT demonstrated uptake in an aorto-caval lymph node and bulky mesenteric disease, which was confirmed at laparotomy as stage IV disease encasing the mesenteric root. Numerous lymph nodes and multifocal primary tumour (7 sub-centimetre lesions) were also found at surgery.

Introduction: Non-resectable tumours involving the mesenteric root are an indication for intestinal and multivisceral transplantation (MVT). Vascularised sentinel forearm flaps (VSFF) offer possibilities for monitoring graft rejection and tailoring immunosuppression (IS) regimens.
