Laparoscopic liver resection of the Spiegel lobe by a left-sided approach preserving an accessory left hepatic artery.

BACKGROUND

Caudate lobe of the liver can be divided in three portions: Spiegel lobe, paracaval portion and caudate process [1]. The anatomy of the caudate lobe and its proximity to major vascular structures makes this operation a difficult resection, especially for laparoscopic liver surgery [2]. For that reason the Iwate criteria proposed to classify this surgery at the "2nd International Consensus Conference on Laparoscopic Liver Resection" as intermediate or advanced difficulty depending on the type of resection, and the size of the tumor [3]. For tumors located in the Spiegel lobe, the left side approach is preferred [4].

METHODS

We present a 69-year-old woman with liver metastasis from previously resected sternal condrosarcoma on 30/05/2017. A unique recurrence in the caudate lobe was found on computed tomography and magnetic resonance imaging on April 2019.

RESULTS

A Spiegel lobe resection with left side approach preserving an accessory left hepatic artery was performed. A resection of the artery was planned if the preservation was not possible. The operative time was 180 min and the total Pringle time was 30 min. Patient was discharged at the 4 postoperative day and there were no postoperative complications CONCLUSIONS: Laparoscopic liver resection of the caudate lobe for condrosarcoma liver metastasis is feasible and safe. Left approach seems the best option for Spiegel lobe resections even in patients with accessory left hepatic artery.
