Abstract
Background There is no accepted way to define difficult donor hepatectomy (DiffDH) during open right live donor hepatectomy (ORLDH). There are also no studies exploring association between DiffDH and early donor outcomes or reliable pre-operative predictors of DiffDH. Methods Consecutive ORLDH performed over 18 months at a single center were included. Intraoperative parameters were used to develop an objective definition of DiffDH. The impact of DiffDH on early postoperative outcomes and achievement of textbook outcome (TO) was evaluated. Donor morphometry data on axial and coronal sections of donor computed tomography (CT) at the level of portal bifurcation were collected. Donor and graft factors predictive of DiffDH were evaluated using univariate and multivariate logistic regression. Results One-hundred-eleven donors (male: 40.5%, age: 34 ± 9.5 years) underwent ORLDH during the study period. The difficulty score was constructed using five intraoperative parameters, i.e., operating time, transection time, estimated blood loss, need for intraoperative vasopressors, and need for Pringle maneuver. Donors were classified as DiffDH (score ≥ 2) or standard donor hepatectomy (StDH) (score <2). Twenty-nine donors (26%) were classified as DiffDH. DiffDH donors suffered greater all-cause morbidity (P = 0.004) but not major morbidity (Clavien-Dindo score >2; P = 0.651), more perioperative transfusion (P = 0.013), increased postoperative systemic inflammatory response syndrome (P = 0.034), delay in achieving full oral diet (P = 0.047), and a 70% reduced chance of achieving TO as compared to StDH (P = 0.007). On logistic regression analysis, increasing right lobe anteroposterior depth (RLdepth) was identified as an independent predictor of DiffDH (Odds ratio: 2.0 (95% confidence interval = 1.2, 3.3), P < 0.006). Receiver operating characteristic curve analysis identified an RLdepth of >14 cm as the best predictor of DiffDH (sensitivity:79%, specificity: 66%, area under curve = 0.803, P < 0.001). Conclusion We report a novel definition of DiffDH and show that it is associated with worse postoperative outcomes, including a lesser chance of achieving TO. We also report that DiffDH can be predicted from readily available donor CT parameters.

Abstract
INTRODUCTION In select clinical scenarios, advanced techniques for volume manipulation and vascular reconstruction are needed for complete hepatic tumor removal. These highly complex liver resections (HCLRs) entail a heightened risk of severe complications. Here, we describe the results of HCLR performed in a 3-year time period. MATERIALS AND METHODS We conducted a retrospective analysis encompassing patients who underwent hepatic resections between June 15, 2020, and June 15, 2023. HCLR was defined according to previously established criteria, and included associating liver partition and portal vein ligation for staged hepatectomy. The outcomes of HCLR were compared to all non-HCLR performed within the same time frame. RESULTS Among 167 hepatic resections, 26 were considered HCLR, and all were major resections. Five utilized total vascular exclusion, with venovenous bypass in three, and hypothermic liver perfusion in three. Five resections included vascular reconstructions, and one included hypothermic circulatory arrest for extraction of a tumor extending to the right atrium. Of the non-HCLR, 38 (26.9%) were major, and 49 (34.7%) were performed laparoscopically. The rates of overall major postoperative complications were comparable between those who underwent HCLR versus non-HCLR. HCLR was associated with increased rates of biliary complications, readmissions, and reoperation. However, no postoperative 90-day mortality was documented within patients that underwent HCLR compared to two in the non-HCLR group. CONCLUSIONS In expert hands, HCLR can be performed with acceptable complication profile, akin to that of major non-HCLR. Those with questionable resectability should be referred to tertiary hepato-pancreato-biliary centers.

Impact of the Intermittent Pringle Maneuver for Predicting Post-hepatectomy Liver Failure: A Cohort Study of 597 Consecutive Patients. World J Surg 2023; 47:1058-1067. [PMID: 36633645 DOI: 10.1007/s00268-023-06904-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/25/2022] [Indexed: 01/13/2023]
Abstract
BACKGROUND Intermittent Pringle maneuver (PM) is widely performed to reduce blood loss during hepatectomy; however, its impact on clinically relevant post-hepatectomy liver failure (PHLF) remains controversial. This study aimed to assess the impact of PM on PHLF and explore whether PM provides additional value for predicting PHLF. METHODS Consecutive patients, who underwent hepatectomy without biliary and/or vascular reconstruction between 2011 and 2018 in a single institution, were retrospectively analyzed. The main outcome was PHLF grades B/C as defined by the International Study Group of Liver Surgery. A multivariable logistic regression model of variables significantly associated with PHLF was established. The model's predictive ability was assessed by the area under the receiver operating characteristic curve (AUROC). RESULTS Among 597 patients, PHLF occurred in 42 (7.0%). PM was applied in 421 patients (70.5%) and was associated with the development of PHLF (PM vs. no-PM: 9.7 vs. 0.6%, P < 0.001). After the propensity score matching, patients with PM experienced significantly increased rates of PHLF (P = 0.010). Rem-ALPlat index (including future liver remnant, preoperative albumin level, and platelet count; P < 0.001), the number of PMs (P = 0.032), and blood loss (P = 0.007) were identified as significant predictors of PHLF. The model's AUROC combined with the intraoperative variables was higher than that of the preoperative model alone (0.877 vs. 0.789, P = 0.004). CONCLUSIONS PM was involved in the occurrence of clinically relevant PHLF. Further, intraoperative factors including PM may provide additional value to predict PHLF and may facilitate early post-hepatectomy intervention.

Abstract
OBJECTIVE The aim of this study was to build a predictive model of operative difficulty in open liver resections (LRs). SUMMARY BACKGROUND DATA Recent attempts at classifying open-LR have been focused on postoperative outcomes and were based on predefined anatomical schemes without taking into account other anatomical/technical factors. METHODS Four intraoperative variables were perceived by the authors as to reflect operative difficulty: operation and transection times, blood loss, and number of Pringle maneuvers. A hierarchical ascendant classification (HAC) was used to identify homogeneous groups of operative difficulty, based on these variables. Predefined technical/anatomical factors were then selected to build a multivariable logistic regression model (DIFF-scOR), to predict the probability of pertaining to the highest difficulty group. Its discrimination/calibration was assessed. Missing data were handled using multiple imputation. RESULTS HAC identified 2 clusters of operative difficulty. In the "Difficult LR" group (20.8% of the procedures), operation time (401 min vs 243 min), transection time (150 vs.63 minute), blood loss (900 vs 400 mL), and number of Pringle maneuvers (3 vs 1) were higher than in the "Standard LR" group. Determinants of operative difficulty were body weight, number and size of nodules, biliary drainage, anatomical or combined LR, transection planes between segments 2 and 4, 4, and 8 or 7 and 8, nonanatomical resections in segments 2, 7, or 8, caval resection, bilioentric anastomosis and number of specimens. The c-statistic of the DIFF-scOR was 0.822. By contrast, the discrimination of the DIFF-scOR to predict 90-day mortality and severe morbidity was poor (c-statistic: 0.616 and 0.634, respectively). CONCLUSION The DIFF-scOR accurately predicts open-LR difficulty and may be used for various purposes in clinical practice and research.
