“…1 Several DSSs have been developed and these are based on parameters such as lesion type, size, location, liver function, extent of liver resection and liver morphology. [2][3][4][5] Tumor size is presently well-recognized as having an important impact on the difficulty of LLR and it has been incorporated into most DSSs. 2,3,6 Larger tumors hinder liver mobilization, alter intraparenchymal vascular topographic anatomy and may require wider parenchymal transections and/or extensive vascular dissections.…”

“…During the Second International Consensus Conference on LLRs held in Morioka in 2014, the panel of experts recommended the use of difficulty scoring systems (DSS) to stratify the technical complexity and risks of LLR, in order to guide surgeons on selecting the appropriate procedure according to their level of experience 1 .

Background Tumor size (TS) represents a critical parameter in the risk assessment of laparoscopic liver resections (LLR). Moreover, TS has been rarely related to the extent of liver resection. The aim of this study was to study the relationship between tumor size and difficulty of laparoscopic left lateral sectionectomy (L‐LLS). Methods The impact of TS cutoffs was investigated by stratifying tumor size at each 10 mm‐interval. The optimal cutoffs were chosen taking into consideration the number of endpoints which show a statistically significant split around the cut‐points of interest and the magnitude of relative risk after correction for multiple risk factors. Results A total of 1910 L‐LLS were included. Overall, open conversion and intraoperative blood transfusion were 3.1 and 3.3%, respectively. The major morbidity rate was 2.7% and 90‐days mortality 0.6%. Three optimal TS cutoffs were identified: 40‐, 70‐, and 100‐mm. All the selected cutoffs showed a significant discriminative power for the prediction of open conversion, operative time, blood transfusion and need of Pringle maneuver. Moreover, 70‐ and 100‐mm cutoffs were both discriminative for estimated blood loss and major complications. A stepwise increase in rates of open conversion rate (Z = 3.90, P < .001), operative time (Z = 3.84, P < .001), blood loss (Z = 6.50, P < .001), intraoperative blood transfusion rate (Z = 5.15, P < .001), Pringle maneuver use (Z = 6.48, P < .001), major morbidity(Z = 2.17, P = .030) and 30‐days readmission (Z = 1.99, P = .047) was registered as the size increased. Conclusion L‐LLS for tumors of increasing size was associated with poorer intraoperative and early postoperative outcomes suggesting increasing difficulty of the procedure. We determined three optimal TS cutoffs (40‐, 70‐ and 100‐mm) to accurately stratify surgical difficulty after L‐LLS.

BackgroundAlthough laparoscopic‐assisted donor hepatectomy (LADH) has become the definitive procedure for harvesting living donor livers, its surgical outcomes in association with donor body shape have not been elucidated.MethodsThe impact of donor factors, including thoracic shape, on LADH outcomes was retrospectively investigated. Thoracic anthropometric data were examined in all LADHs with a left/right graft between 2013 and 2022.ResultsThe study included 210 LADHs, consisting of 106 left‐ and 104 right‐lobe donors with similar blood loss and similar operation time. Males have greater thoracic depth and greater thoracic width compared with females, respectively. Thoracic depth was associated with graft weight (p < 0.001), blood loss (p < 0.001), and operation time (p < 0.001). On multivariate analyses, blood loss >500 mL and operation time >8 h were associated with graft weight in the left‐lobe donors, and blood loss >500 mL was associated with thoracic depth in the right‐lobe donors.ConclusionThe greater thoracic depth is associated with massive blood loss in right‐lobe donors. Anthropometric parameters might be helpful for estimating LADH outcomes.
