915 MHz microwave-assisted laparoscopic partial splenectomy: A case series

Area of Science:

• Surgical Oncology
• Minimally Invasive Surgery
• Medical Devices

Background:

• Hemorrhage during splenic parenchyma transection is a significant risk in laparoscopic partial splenectomy (LPS).
• Evaluating novel techniques to improve safety and efficacy in LPS is crucial.

Purpose of the Study:

• To assess the feasibility and safety of using a 915 MHz microwave (MW) device for pre-coagulation during LPS.
• To determine the effectiveness of MW pre-coagulation in minimizing blood loss and ensuring complete tumor resection.

Main Methods:

• Retrospective analysis of data from four patients who underwent LPS with 915 MHz MW pre-coagulation.
• Patients had splenic unifocal lesions (mean diameter 4.6 cm).
• Surgical outcomes including operative time, blood loss, complications, and hospital stay were recorded.

Main Results:

• Successful R0 resection (complete resection without microscopic residual tumor) was achieved in all patients.
• Mean operative time was 205 minutes with minimal blood loss (30-50 ml).
• No complications were observed, and hospital stay ranged from 5 to 10 days.

Conclusions:

• Pre-coagulation with a 915 MHz MW device is a safe and efficient method for LPS.
• This technique shows promise for controlling hemorrhage and achieving oncological goals in partial splenectomy.
• Further extensive studies are warranted to validate these findings for broader clinical application.
