Long-term outcomes of resection in patients with symptomatic benign liver tumours

Background: Benign liver tumours (e.g., hepatocellular adenoma (HCA), focal nodular hyperplasia (FNH), and haemangioma) are occasionally resected for alleged symptoms, although data on long-term outcomes is lacking. The aim of this cross-sectional study was to assess long-term outcomes of surgical intervention. Methods: Forty patients with benign tumours (HCA 20, FNH 12, giant haemangioma 4, cysts 4) were included. Patients filled in Validated McGill Pain Questionnaires, preoperatively and after a median of 54 months after resection. Outcomes were evaluated using paired sample t-test and (M) ANOVA. Results: Relief of symptoms sustained in 30/40 patients, within a follow-up of 54 (24-148) months after resection. VAS scores were reduced from 5.5 preoperatively to 1.6 postoperatively (p < 0.001). Patients with left-sided tumours had higher postoperative Pain Rating Index (PRI), compared to patients with right-sided tumours: 15.3 vs. 5.8 (p = 0.018). If patients could reconsider undergoing surgery, 34/38 would again choose resection. Discomfort at the operative scar was the most common complaint: 8/40 patients, all after open surgery, of whom 3/40 had an incisional hernia. 7/40 patients had a laparoscopic resection. Conclusion: Resection relieved symptoms in 30/40 patients. The operative scar was a frequent source for remaining postoperative complaints, suggesting an advantage for a laparoscopic approach when feasible.
