Clinical effect of laparoscopic partial splenectomy for both benign tumours and trauma‐10 years of experience at a single institution

This retrospective study aimed to present our surgical experience in patients with benign tumour or trauma in spleen who underwent laparoscopic partial splenectomy (LPS) and to compare the results with those of patients who underwent an open partial splenectomy (OPS).We analysed the medical data of patients who underwent LPS or OPS between January 2010 and January 2020.In total, 41 patients were enrolled. Nine patients underwent open surgery, 32 patients underwent laparoscopic surgery. The proportion of patients with tumours in the upper pole in LPS group was more than patients in OPS group. No difference was observed in estimated blood loss, allogeneic transfusion, postoperative stay, pathology and complications between LPS and OPS groups. The operation time in the LPS group (137.5 ± 30.8 min) was longer than that in the OPS group (88.3 ± 30.1 min) for patients with splenic traumatic rupture (P = 0.019).LPS is an effective and safe spleen-preserving surgery as OPS. The advantages are small trauma, light pain and quick recovery. It is suitable for patients with benign tumours or trauma confined to one side of the spleen.
