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.
