Background
Although laparoscopic liver resection (LLR) is now considered a standard procedure in peripheral segments, there are few reports on laparoscopic segment 1 (Sg1) resection. The aim of this study was to assess both safety and feasibility of Sg1 LLR.
Methods
From 2000 to 2014, all patients who underwent LLR were identified from a prospective database. Patients with resection of Sg1 (Sg1 group) were compared with those with resection of anteroinferior segments (AI group: segments 3, 4b, 5, 6) or posterosuperior segments (PS group: segments 4a, 7, 8), in terms of tumor characteristics, surgical treatment, and short-term outcomes.
Results
There were 15, 151, and 67 patients in Sg1, AI, and PS groups. Tumor size and tumor number were similar between the three groups (p = 0.139, p = 0.102). Operative time was significantly shorter in Sg1 (150 min) and AI group (135 min) compared with PS group (180 min) (p = 0.021). Median blood loss was notably higher in PS group (140 ml) compared with Sg1 group (75 ml) and AI group (10 ml) (p = 0.001). No mortality was observed in all groups. Postoperative complication rate was 20.0 % with Sg1 group, 14.6 % with AI group, and 20.9 % with PS group (p = 0.060). The rate of major complication was significantly higher in Sg1 group (13.3 %) and PS group (11.9 %) compared with AI group (4.0 %) (p = 0.042). Resection margins were clear in all Sg1 and PS group patients, whereas two (1.3 %) patients in AI group had R1 margins (p = 0.586).
Conclusion
The laparoscopic approach of isolated resection located in the caudate lobe is a feasible and curative surgical option in selected patients.
