Handheld gamma probe used to detect accessory spleens during initial laparoscopic splenectomies

Area of Science:

• Surgical oncology
• Medical imaging
• Nuclear medicine

Background:

• Accessory spleens pose a challenge in splenectomy, impacting surgical outcomes.
• Preoperative imaging for accessory spleens has limited sensitivity.
• Accurate localization is crucial for successful surgical intervention.

Purpose of the Study:

• To assess the utility of a handheld gamma probe for identifying accessory spleens.
• To compare gamma probe efficacy against other preoperative and intraoperative methods.
• To improve the detection of accessory splenic tissue during laparoscopic splenectomy.

Main Methods:

• 17 patients with benign hematologic disorders undergoing laparoscopic splenectomy were studied.
• Preoperative imaging included ultrasonography, CT scan, and nuclear scintigraphy.
• A handheld gamma probe was used intraoperatively to detect accessory splenic tissue.

Main Results:

• The gamma probe demonstrated 100% sensitivity in detecting accessory splenic tissue.
• It identified an accessory spleen missed by preoperative CT scan in one case.
• Ultrasonography and preoperative nuclear scintigraphy had 0% sensitivity.

Conclusions:

• Handheld gamma probe is a valuable adjuvant tool for laparoscopic splenectomy.
• It significantly enhances the detection of accessory splenic tissue.
• This improves the success rate of initial surgical treatment for benign hematologic disorders.
