Background:
Haemorrhage during the splenic parenchyma transection is a major threat for laparoscopic partial splenectomy (LPS). We here aim to evaluate the feasibility and safety of pre-coagulation of a 915 MHz microwave (MW) device during LPS.
Materials And Methods:
Data of four patients admitted to our hospital between November 2016 and July 2018 were retrospectively analysed. The mean age was 24 years (range, 19-33); they all diagnosed with splenic unifocal lesion with a mean diameter of 4.6 cm (ranged from 3.7 to 6 cm) and underwent LPS with pre-coagulation of a 915 MHz MW.
Results:
The LPS with pre-coagulation was successfully resulted in complete resection without microscopic residual tumour (R0 resection). The mean operative time was 205 min, and the minimum blood loss was at the range of 30-50 ml. No complication was observed, and the length of stay in hospital was varied from 5 to 10 days.
Conclusion:
Based on our observation, pre-coagulation of a 915 MHz MW during LPS is a safe and efficient technique. More studies are required before applying extensively.
Insights
Pre-coagulation using a 915 MHz microwave (MW) device during laparoscopic partial splenectomy (LPS) effectively controls bleeding. This safe and efficient technique achieved complete tumor resection with minimal blood loss in a small patient cohort.
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.
