Summary
Laparoscopic ultrasonography is a feasible technique for locating and resecting insulinomas, offering a safe option for patients with hyperinsulinism and leading to faster recovery.
Area of Science:
- Minimally Invasive Surgery
- Gastroenterology
- Endocrinology
Background:
- Laparoscopic ultrasonography for islet cell tumor localization is documented.
- Laparoscopic resection of insulinomas is less frequently reported.
- This study evaluates the feasibility of laparoscopic detection and resection of insulinomas.
Purpose of the Study:
- To assess the feasibility of laparoscopic ultrasonography for insulinoma localization.
- To evaluate the outcomes of laparoscopic resection for insulinomas.
- To determine the safety and efficacy of this minimally invasive approach.
Main Methods:
- Retrospective review of 10 patients with organic hyperinsulinism (February 1996 - February 1999).
- Preoperative localization using various imaging techniques and intraoperative laparoscopic ultrasonography.
- Laparoscopic resection (enucleation or pancreatic tail resection) or conversion to laparotomy.
Main Results:
- Laparoscopic resection was successful in 6 out of 10 patients (60%).
- Laparoscopic ultrasonography identified insulinomas in 90% of patients (9/10).
- Median hospital stay was 7 days, with low morbidity.
Conclusions:
- Laparoscopic ultrasonography and resection are feasible and safe for insulinoma management.
- This approach offers low morbidity and rapid recovery for patients with hyperinsulinism.
- Preoperative localization studies showed limited value compared to intraoperative findings.
