Summary

Preoperative localization of gastrinomas frequently fails. Surgical exploration with intraoperative ultrasound and duodenal exploration is crucial for successful tumor identification and curative resection.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Endocrinology

Context:

  • Gastrinomas, neuroendocrine tumors secreting gastrin, present diagnostic challenges.
  • Preoperative imaging often fails to localize these tumors accurately.
  • Biochemical confirmation and exclusion of metastases are prerequisites for surgical intervention.

Purpose:

  • To outline a surgical strategy for gastrinoma localization and resection when preoperative imaging is insufficient.
  • To detail the techniques for intraoperative tumor identification and management.
  • To emphasize the importance of complete tumor resection for curative outcomes.

Summary:

  • Meticulous surgical exploration, including intraoperative ultrasound (IOUS) and duodenotomy with duodenal exploration, can identify over 90% of primary gastrinomas.

  • Surgical approaches vary by tumor location: duodenal wall excision, pancreatic head enucleation, or distal pancreatectomy.
  • For Multiple Endocrine Neoplasia type 1 (MEN-1) related gastrinomas, spleen-preserving distal pancreatectomy and pancreatic head enucleation are recommended.

    • Impact:

    • Successful surgical management leads to complete tumor resection, offering the only curative approach for patients with gastrinomas.
    • This strategy improves diagnostic yield and patient outcomes in challenging gastrinoma cases.
    • Tailored surgical techniques, including pylorus-preserving pancreaticoduodenectomy, can be employed based on preoperative localization via methods like SASI angiography.
