Laparoscopic surgery for pancreatic insulinomas: an update

Area of Science:

• Endocrinology
• Surgical Oncology
• Gastroenterology

Background:

• Insulinomas are the most frequent functioning neuroendocrine tumors of the pancreas.
• Unlike other pancreatic neuroendocrine tumors, insulinomas are usually benign and solitary.
• Surgical excision is the primary treatment, yielding excellent long-term outcomes.

Purpose of the Study:

• To review the current status of laparoscopic management for insulinoma.
• To highlight technical details of common laparoscopic procedures for insulinoma.
• To identify unresolved issues in the laparoscopic treatment of insulinoma.

Main Methods:

• Preoperative localization using a combination of invasive and non-invasive imaging modalities.
• Intraoperative localization confirmed with laparoscopic ultrasound.
• Surgical excision via minimally invasive laparoscopic techniques.

Main Results:

• Minimally invasive laparoscopic surgery for insulinoma is gaining popularity.
• Laparoscopic approaches offer shorter hospital stays and better cosmetic results.
• Serious complication rates are comparable to open surgery.

Conclusions:

• Laparoscopic management of insulinoma is effective, with encouraging results from specialized centers.
• Preoperative and intraoperative localization are critical for successful surgical planning.
• Further research, potentially through randomized trials, is needed to definitively validate these findings due to the rarity of insulinoma.
