Feasibility of laparoscopic liver resection for liver cavernous hemangioma: A single-institutional comparative study

BACKGROUNDS/AIMS: While minimal invasive surgery has become popular, the feasibility of laparoscopy for liver cavernous hemangioma has not been shown. METHODS: Patients who underwent hepatectomy for liver cavernous hemangioma from January 2008 to February 2019 at the Samsung Medical Center were reviewed. Patients who underwent trisectionectomy were excluded. Background characteristics, along with operative and postoperative recovery, were compared between the laparoscopy and open surgery groups. RESULTS: Forty-three patients in the laparoscopy group and 33 patients in the open surgery group were compared. The differences in the background characteristics were presence of symptoms (14.6% in laparoscopy vs. 57.1% in open, p<0.001) and tumor location (right, left and both side p=0.017). The laparoscopy group had smaller blood loss (p=0.001), lesser blood transfusion requirements (p=0.035), lower level of post-operative total bilirubin, prothrombin time (INR) (p=0.001, 0.003 each), shorter hospital stay (p=0.001), earlier soft diet start (p<0.001), earlier drain removal (p<0.001) and shorter amount and duration of additional pain control (p=0.001, p=0.017 each). There was no significant difference in complication after surgery between two groups (p=0.721). All the patients showed pathologic report of benign hemangioma regardless of type of surgery (100%). Almost every patients reported no symptom or relief of symptom in both groups (97.7%, 93.9% each). CONCLUSIONS: Laparoscopic liver resection for liver cavernous hemangioma can be safely performed with improved postoperative recovery. However, surgery for liver cavernous hemangioma should be conducted with informed consent of the patients.
