title: Solitary hepatic gastrinoma treated with laparoscopic radiofrequency ablation.
abstract: BACKGROUND
  This is a case of a solitary hepatic gastrinoma in a 65-year-old male. The patient was diagnosed with Zollinger-Ellison syndrome in 1991. He had negative radiologic and surgical explorations at that time. He was maintained on proton-pump inhibitors for the next 10 years without symptoms.
  
  
  METHODS
  A computed tomographic (CT) scan done in April 2001 demonstrated a 5-cm right hepatic lesion. Radionucleotide scanning with octreotide demonstrated intense activity in the same area in the right hepatic lobe. His serum gastrin was 317 pg/mL. He underwent laparoscopic radiofrequency ablation of the lesion.
  
  
  RESULTS
  Treatment resulted in a 6-cm ablative area giving a 1-cm margin on the tumor. One- and 3-month follow-up CT scans demonstrated adequate ablation of the tumor. An octreotide scan done 3 months postoperatively did not reveal any areas of abnormal uptake.
  
  
  CONCLUSIONS
  We report success with laparoscopic radiofrequency ablation as an alternative to major hepatic resection in patients with a solitary hepatic gastrinoma.
