[Surgical management of persistent diarrhea].

An 82-year-old patient presented with a cervical lesion and refractory diarrhea of many years' standing. Surgical therapy of a medullary thyroid carcinoma had been performed 16 years previously. Appropriate tumor follow-up had not been carried out hitherto. Significantly high levels of calcitonin as well as a suspicious octreotide scan indicated late recurrence of the disease. Diarrhea ceased following redo surgery.
