“…The possibility of differences in liver volume among races has been reported, and the variety of formulas reported by different countries support such a difference [27,28]. The body frame differs significantly between Asian and Caucasian populations [29].…”

“…A 3‐dimensional (3D) imaging analysis system 19 calculated remnant liver volume (RLV) and visualized the vascular and biliary tract anatomy and the spatial location of the large masses (Figure 1B). The standard liver volume (SLV) was calculated following the experience of Urata et al20, 21 For patients with highly suspected extrahepatic metastases, positron emission tomography‐computed tomography (PET‐CT) was essential to determine whether there were any potential surgical contraindications. Ultrasonography (US) evaluation of the large abdomen vessels was necessary to assess the vascular flow status and the presence or absence of “rich collateral circulation.”22 US of the bilateral great saphenous vein (GSV) was performed to evaluate its diameter and length for the reconstruction of the RHVC.…”

Ex vivo liver resection combined with autotransplantation is a recently introduced approach to cure end‐stage hepatic alveolar echinococcosis (HAE), which is considered unresectable by conventional radical resection due to echinococcal dissemination into the crucial intrahepatic conduits and adjacent structures. This article aims discuss the manipulation details and propose reasonable indications for this promising technique. All patients successfully underwent liver autotransplantation with no intraoperative mortality. The median weight of the autografts was 636 g (360‐1300 g), the median operation time was 12.5 hours (9.4‐19.5 hours), and the median anhepatic phase was 309 minutes (180‐ 460 minutes). Intraoperative blood loss averaged 1800 mL (1200‐6000 mL). Postoperative complications occurred in 13 patients during hospitalization; 5 patients experienced postoperative complications classified as Clavien‐Dindo grade III or higher, and 2 patients died of intraabdominal bleeding and acute cerebral hemorrhage, respectively. Twenty‐nine patients were followed for a median of 14.0 months (3‐42 months), and no HAE recurrence was detected. The technique requires neither an organ donor nor any postoperative immunosuppressant, and the success of the treatment relies on meticulous preoperative assessments and precise surgical manipulation.

“…For these reasons, some authors have proposed the use of conversion factors and formulas, which should standardize imaging volumetry, providing a more realistic evaluation of liver volume [45,46] . Tongyoo et al [47] , for example, proposed a formula that combined sonographic portal vein diameters measurement and CT liver volumetry, providing a precise donor screening for graft size adequacy. Sakei et al [48] proposed another formula to calculate the standard liver volume of children undergoing liver transplantation (standard liver volume = 689.9 × body surface area -24.7), using CT images as a reference.…”

The amount of the future liver remnant volume is fundamental for hepato-biliary surgery, representing an important potential risk-factor for the development of post-hepatectomy liver failure. Despite this, there is no uniform consensus about the amount of hepatic parenchyma that can be safely resected, nor about the modality that should be chosen for this evaluation. The pre-operative evaluation of hepatic volume, along with a precise identification of vascular and biliar anatomy and variants, are therefore necessary to reduce surgical complications, especially for extensive resections. Some studies have tried to validate imaging methods [ultrasound, computed tomography (CT), magnetic resonance imaging] for the assessment of liver volume, but there is no clear evidence about the most accurate method for this evaluation. Furthermore, this volumetric evaluation seems to have a certain degree of error, tending to overestimate the actual hepatic volume, therefore some conversion factors, which should give a more reliable evaluation of liver volume, have been proposed. It is widespread among non-radiologists the use of independent software for an off-site volumetric analysis, performed on digital imaging and communications in medicine images with their own personal computer, but very few studies have provided a validation of these methods. Moreover, while the pre-transplantation volumetric assessment is fundamental, it remains unclear whether it should be routinely performed in all patients undergoing liver resection. In this editorial the role of imaging in the estimation of liver volume is discussed, providing a review of the most recent literature and a brief personal series of correlations between liver volumes and resection specimens' weight, in order to assess the precision of the volumetric CT evaluation.
