Abstract
BACKGROUND Studies on pure laparoscopic donor hepatectomy (PLDH) have been reported. However, only few studies have reported on the learning curve of PLDH. In this report, we aimed to determine the learning curve of PLDH in adult patients using cumulative sum (CUSUM) and risk-adjusted CUSUM (RA-CUSUM) analyses. METHODS The data of donors who underwent PLDH at a single center between December 2012 and May 2022 were retrospectively reviewed. The learning curve was evaluated using the CUSUM and RA-CUSUM methods based on surgery duration. RESULTS Forty-eight patients were finally included in the present study. The mean operation time was 393.6 ± 80.3 min. PLDH was converted to laparotomy in three cases (6.3%). According to the Clavien-Dindo classification, nine cases (18.8%) had higher-than-grade III postoperative complications and the most frequent complications were biliary complications. The CUSUM graph shows two peaks, at the 13th and 27th case. The multivariate analysis revealed that a body mass index ≥ 23 kg/m2 and intraoperative cholangiography were the only factors that were independently associated with longer operation time. Based on these results, an RA-CUSUM analysis was performed to assess the learning curve, which showed a decrease in the learning curve after 33 to 34 PLDH procedures. CONCLUSIONS A learning curve effect was demonstrated in this study after 33 to 34 PLDH procedures. There are relatively many biliary complications, and it is necessary to further examine the method of bile duct transection.

Abstract
BACKGROUND AND OBJECTIVE Minimally invasive liver surgery is evolving worldwide, and robot-assisted liver surgery (RLS) can deliver obvious benefits for patients. However, so far no large case series have documented the learning curve for RLS. METHODS We conducted a retrospective study for robotic liver surgery (RLS) from June 2019 to June 2022 where 100 patients underwent RLS by the same surgical team. Patients' variables, short-term follow-up, and the learning curve were analyzed. A review of the literature describing the learning curve in RLS was also conducted. RESULTS Mean patient age was 63.1 years. The median operating time was 246 min and median estimated blood loss was 100 mL. Thirty-two patients underwent subsegmentectomy, 18 monosegmentectomies, 25 bisegmentectomies, and 25 major hepatectomies. One patient (1.0%) required conversion to open surgery. Five patients (5%) experienced postoperative major complications, and no mortalities occurred. Median length of hospital stay was 3 days. R0 resection was achieved in 93.4% of the malignant cases. The learning curve consisted of three stages; there were no significant differences in operative time, transfusion rate, or complication rate among the three groups. Postoperative complications were similar in each group despite an increase in surgical difficulty scores. The learning effect was highlighted by significantly shorter hospital stays in cohorts I, II, and III, respectively. The included systematic review suggested that the learning curve for RLS is similar to, or shorter, than that of laparoscopic liver surgery. CONCLUSIONS In our experience, RLS has achieved good clinical results, albeit in the short term. Standardization of training leads to increasing proficiency in RLS with reduced blood loss and low complication rates even in more advanced liver resections. Our study suggests that a minimum of 30 low-to-moderate difficulty robotic procedures should be performed before proceeding to more difficult resections.

Impact of liver cirrhosis, the severity of cirrhosis, and portal hypertension on the outcomes of minimally invasive left lateral sectionectomies for primary liver malignancies. Surgery 2023; 174:581-592. [PMID: 37301612 PMCID: PMC10986843 DOI: 10.1016/j.surg.2023.04.057] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2023] [Revised: 04/08/2023] [Accepted: 04/27/2023] [Indexed: 06/12/2023]
Abstract
BACKGROUND The impact of cirrhosis and portal hypertension on perioperative outcomes of minimally invasive left lateral sectionectomies remains unclear. We aimed to compare the perioperative outcomes between patients with preserved and compromised liver function (noncirrhotics versus Child-Pugh A) when undergoing minimally invasive left lateral sectionectomies. In addition, we aimed to determine if the extent of cirrhosis (Child-Pugh A versus B) and the presence of portal hypertension had a significant impact on perioperative outcomes. METHODS This was an international multicenter retrospective analysis of 1,526 patients who underwent minimally invasive left lateral sectionectomies for primary liver malignancies at 60 centers worldwide between 2004 and 2021. In the study, 1,370 patients met the inclusion criteria and formed the final study group. Baseline clinicopathological characteristics and perioperative outcomes of these patients were compared. To minimize confounding factors, 1:1 propensity score matching and coarsened exact matching were performed. RESULTS The study group comprised 559, 753, and 58 patients who did not have cirrhosis, Child-Pugh A, and Child-Pugh B cirrhosis, respectively. Six-hundred and thirty patients with cirrhosis had portal hypertension, and 170 did not. After propensity score matching and coarsened exact matching, Child-Pugh A patients with cirrhosis undergoing minimally invasive left lateral sectionectomies had longer operative time, higher intraoperative blood loss, higher transfusion rate, and longer hospital stay than patients without cirrhosis. The extent of cirrhosis did not significantly impact perioperative outcomes except for a longer duration of hospital stay. CONCLUSION Liver cirrhosis adversely affected the intraoperative technical difficulty and perioperative outcomes of minimally invasive left lateral sectionectomies.

Abstract
BACKGROUND The laparoscopic Pringle maneuver is crucial for controlling bleeding during laparoscopic hepatectomy. In this study, we introduce a new laparoscopic Pringle maneuver and preliminarily investigate its application in laparoscopic hepatectomy. METHODS We collected and analyzed the clinical data of 17 consecutive patients who underwent laparoscopic hepatectomy at the Department of Hepatic Surgery, the First Affiliated Hospital of the University of Science and Technology of China, from January 2022 to January 2023. All patients underwent the hooking method for intermittent occlusion of hepatic inflow. Intraoperative and postoperative clinical indices were observed and recorded. RESULTS All 17 patients underwent laparoscopic hepatectomy with hepatic inflow control using the hooking method. Four patients with adhesions under the hepatoduodenal ligament successfully had occlusion loops placed using the hooking method combined with Zhang's modified method during surgery. The median occlusion time for the 17 patients was 34 (12-60) min, and the mean operation time was 210 ± 70 min. The mean intraoperative blood loss was 145 ± 86 ml, and no patients required intraoperative blood transfusion. The patients' postoperative peak AST was 336 ± 183 U/L, and the postoperative peak ALT was 289 ± 159 U/L. Postoperative complications occurred in 2 patients (11.8%), including 1 Clavien-Dindo grade I and 1 Clavien-Dindo grade II complication. No Clavien-Dindo grade IIIa or higher complications or deaths occurred in any patient. None of the patients developed portal vein thrombosis or hepatic artery aneurysm formation. The median postoperative hospital stay was 6 (4-14) days. CONCLUSION The hooking method combines the advantages of both intracorporeal Pringle maneuver and extracorporeal Pringle maneuver. It is a simple, safe, and effective method for controlling hepatic inflow and represents a promising approach for performing totally intracorporeal laparoscopic Pringle maneuver.

Abstract
BACKGROUND Post-hepatectomy liver failure (PHLF) represents the major source of mortality after liver resection (LR) in hepatocellular carcinoma (HCC) patients. Child-Pugh (CP) score 5 is always considered to indicate a normal liver function but represents a heterogeneous population with a considerable number suffering from PHLF. The present study aimed to access the ability of liver stiffness (LS) measured by two-dimensional shear wave elastography (2D-SWE) to predict PHLF in HCC patients with a CP score of 5. METHODS From August 2018 to May 2021, 146 HCC patients with a CP score of 5 who underwent LR were reviewed. The patients were randomly divided into training (n = 97) and validation (n = 49) groups. Logistic analyses were conducted for the risk factors and a linear model was built to predict the development of PHLF. The discrimination and calibration were assessed in the training and validation cohorts by the areas under the receiver operating characteristic curve (AUC). RESULTS Analyses revealed that the minimum of LS (Emin) higher than 8.05 (p = 0.006, OR = 4.59) and future liver remnant / estimated total liver volume (FLR/eTLV) (p < 0.001, OR < 0.01) were independent predictors of PHLF in HCC patients with CP score 5, and the AUC calculated by the model based on them for differentiation of PHLF in the training and validation group was 0.78 and 0.76, respectively. CONCLUSION LS was associated with the development of PHLF. A model combining Emin and FLR/eTLV showed proper ability in predicting PHLF in HCC patients with a CP score of 5.

Cancers (Basel) 2023; 15:cancers15020488. [PMID: 36672437 PMCID: PMC9856586 DOI: 10.3390/cancers15020488] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Revised: 01/09/2023] [Accepted: 01/11/2023] [Indexed: 01/15/2023] Open
Abstract
Laparoscopic liver resection (LLR) is widely accepted in the surgical treatment of hepatocellular carcinoma (HCC) through international consensus conferences and the development of difficulty classifications. LLR has been reported to result in earlier postoperative recovery and fewer postoperative complications than open liver resection (OLR) for HCC. However, the prevalence of liver cirrhosis, obesity, the elderly, HCC recurrence (repeat liver resection), and major resection must be considered for LLR for HCC. Some systematic reviews, meta-analysis studies, and large cohort studies indicated that LLR is technically feasible for selected patients with HCC with these factors that led to less intraoperative blood loss, fewer transfusions and postoperative complication incidences, and shorter hospital stays than OLR. Furthermore, some reported LLR prevents postoperative loss of independence. No difference was reported in long-term outcomes among patients with HCC who underwent LLR and OLR; however, some recent reports indicated better long-term outcomes with LLR. In recent years, robot-assisted liver resection (RALR) has gradually become popular, and its short- and long-term results for HCC are not different from those of LLR. Additionally, RALR is expected to become the mainstay of minimally invasive surgery in the future.

Abstract
BACKGROUND Minimally invasive liver resection is associated with lower perioperative morbidity and shorter hospital stay. However, the added benefit of the robotic platform over conventional laparoscopy is a matter of ongoing investigation. PURPOSE The purpose of this narrative review is to provide an up-to-date and balanced evaluation of the benefits and shortcomings of robotic liver surgery for the modern hepatobiliary surgeon. CONCLUSIONS Advantages of a robotic approach to liver resection include a shortened learning curve, the ability to complete more extensive or complex minimally invasive operations, and integrated fluorescence guidance. However, the robotic platform remains limited by a paucity of parenchymal transection devices, complete lack of haptic feedback, and added operating time associated with docking and instrument exchange. Like laparoscopic hepatectomy, robotic hepatectomy may provide patients with more rapid recovery and a shorter hospital stay, which can help offset the substantial costs of robot acquisition and maintenance. The oncologic outcomes of robotic hepatectomy appear to be equivalent to laparoscopic and open hepatectomy for appropriately selected patients.

A chronological review of 500 minimally invasive liver resections in a North American institution: overcoming stagnation and toward consolidation. Surg Endosc 2022; 36:6144-6152. [PMID: 35277772 DOI: 10.1007/s00464-022-09182-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Accepted: 02/27/2022] [Indexed: 12/07/2022]
Abstract
BACKGROUND Although interest in expanding the application of minimally invasive liver resection (MILR) is high the world over, most of the extensive experience in MILR has been reported from Far East Asia and Europe and its adoption in North America is limited. The aim of this study was to review the experience of MILR in a single North American institute over a 15-year period, highlighting both the obstacles encountered and strategies adopted to overcome the stagnation in its uptake. METHODS This study included 500 MILR cases between 2006 and 2020. Patient demographics, disease characteristics, surgical technique, and perioperative outcomes are summarized. The major hepatectomy rate and conversion rate were assessed according to case numbers (first 100, 101-300, and 301-500 cases) to assess chronological trends. RESULTS Of 500, 402 MILRs were done by pure laparoscopic (80.4%), 67 were hand assisted (13.4%), and 31 were robotic (6.2%). The majority (64%) of cases were performed for malignancy (n = 320; 100 Hepatocellular carcinoma, 153 Colorectal metastases, 27 Intrahepatic cholangiocarcinoma, and others, 40, 64%). A total of 71 cases were converted to open (14.2%). The annual case number gradually increased over the first few years; however, case numbers stayed around 30 between 2009 and 2017. In this period, despite accumulating MILR experience, open conversion rates increased despite no change in major hepatectomy rate. After this period of long-term stagnation, we introduced crucial changes in team composition and laparoscopic instrumentation. Our MILR case number and major hepatectomy rate thereafter increased significantly without increasing conversion or complication rates. CONCLUSION Our recovery from long-term stagnation by instituting key changes as detailed in this study could be used as a guidepost for programs that are contemplating transitioning their MILR program from minor to advanced resections. Establishing a formal MILR training model through proper mentorship/proctorship and building a dedicated MILR team would be imperative to this strategy.

Abstract
BACKGROUND A shift towards parenchymal-sparing liver resections in open and laparoscopic surgery emerged in the last few years. Laparoscopic liver resection is technically feasible and safe, and consensus guidelines acknowledge the laparoscopic approach in the posterosuperior segments. Lesions situated in these segments are considered the most challenging for the laparoscopic approach. The aim of this trial is to compare the postoperative time to functional recovery, complications, oncological safety, quality of life, survival and costs after laparoscopic versus open parenchymal-sparing liver resections in the posterosuperior liver segments within an enhanced recovery setting. METHODS The ORANGE Segments trial is an international multicentre randomised controlled superiority trial conducted in centres experienced in laparoscopic liver resection. Eligible patients for minor resections in the posterosuperior segments will be randomised in a 1:1 ratio to undergo laparoscopic or open resections in an enhanced recovery setting. Patients and ward personnel are blinded to the treatment allocation until postoperative day 4 using a large abdominal dressing. The primary endpoint is time to functional recovery. Secondary endpoints include intraoperative outcomes, length of stay, resection margin, postoperative complications, 90-day mortality, time to adjuvant chemotherapy initiation, quality of life and overall survival. Laparoscopic liver surgery of the posterosuperior segments is hypothesised to reduce time to functional recovery by 2 days in comparison with open surgery. With a power of 80% and alpha of 0.04 to adjust for interim analysis halfway the trial, a total of 250 patients are required to be randomised. DISCUSSION The ORANGE Segments trial is the first multicentre international randomised controlled study to compare short- and long-term surgical and oncological outcomes of laparoscopic and open resections in the posterosuperior segments within an enhanced recovery programme. TRIAL REGISTRATION ClinicalTrials.gov NCT03270917 . Registered on September 1, 2017. Before start of inclusion. PROTOCOL VERSION version 12, May 9, 2017.

Learning Curve for Metastatic Liver Tumor Open Resection in Patients with Primary Colorectal Cancer: Use of the Cumulative Sum Method. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19031068. [PMID: 35162093 PMCID: PMC8834355 DOI: 10.3390/ijerph19031068] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/05/2021] [Revised: 01/16/2022] [Accepted: 01/17/2022] [Indexed: 02/05/2023]
Abstract
Background: Liver resections have become the first-line treatment for primary and metastatic tumors and, therefore, are considered a core aspect of surgical training. This study aims to evaluate the learning curve of the extent and safety of liver resection procedures for patients with metastatic colorectal cancer. Methods: This single tertiary center retrospective analysis includes 158 consecutive cases of small liver resection (SLR) (n = 107) and major liver resection (MLR) (n = 58) procedures. A cumulative sum control chart (CUSUM) method was used to investigate the learning curve. Results: The operative time, total blood loss level, and incidence of adverse effects showed a learning curve. For SLRs, the CUSUM curve for operative time and blood loss level peaked at the 19th and 17th case, respectively, while for MLRs, these curves peaked at the 28th and 24th case, respectively. The CUSUM curve for minor adverse effects (MAEs) and severe adverse effects (SAEs) showed a downward slope after the 16th and 68th procedures in the SLRs group and after the 29th and 39th procedures in the MLRs cohort; however, it remained within the acceptable range throughout the entire study. Conclusion: SLR procedures were performed faster with less intraoperative blood loss and shorter postoperative stays than MLRs, and a higher number of completed procedures was required to gain stabilization and repeatability in the operating time and intraoperative blood loss level. In MLR procedures, the reduction of SAEs was accomplished significantly later than the stabilization of the operative time and intraoperative blood loss level.

Abstract
INTRODUCTION We performed this study in order to investigate the impact of tumour size on the difficulty of MILR, as well as to elucidate the optimal tumour size cut-off/s to distinguish between 'easy' and 'difficult' MILRs. MATERIALS AND METHODS This is retrospective review of 603 consecutive patients who underwent MILR between 2006 and 2019 of which 461 met the study inclusion criteria. We first conducted an exploratory analysis to visualize the associations between tumor size and various surrogates of laparoscopic difficulty in order to determine to optimal tumor size cutoff for stratification. Visual inspection of flexible spline-based models as well as quantitative evidence determined that perioperative outcomes differed between patients with tumor size of 30-69 mm and tumours ≥70 mm. These cutoffs were used for further downstream analyses. RESULTS The cohort of 461 patients was divided into 3 groups based on tumour diameter size. Patients with larger tumours experienced longer operating times ((PGroup 2 vs 1<0.001, PGroup 3 vs 1<0.001, PGroup 3 vs 2<0.001), higher blood loss (PGroup 2 vs 1<0.001, PGroup 3 vs 1<0.001, PGroup 3 vs 2<0.001), as well as significantly longer hospital stay (PGroup 2 vs 1<0.001, PGroup 3 vs 1<0.001, PGroup 3 vs 2<0.001). There was a monotonic trend towards increasing blood transfusion rates (P = 0.006), overall morbidity (P = 0.029) and 90-day mortality rates (P = 0.047) with increasing tumour size. CONCLUSION Although tumour size of 30 mm serves as an optimal cut-off for predicting difficult resections as per the Iwate criteria, a trichotomy (<30 mm, 30-69 mm, ≥70 mm) may provide additional granularity. Further large-scale prospective studies are needed to corroborate these findings.

Abstract
BACKGROUND Minimally invasive hepatectomy (MIH) has become an important option for the treatment of various liver tumours. A major concern is the learning curve required. The aim of this study was to perform a systematic review and summarize current literature analysing the learning curve for MIH. METHODS A systematic review of the literature pertaining to learning curves in MIH to July 2019 was performed using PubMed and Scopus databases. All original full-text articles published in English relating to learning curves for both laparoscopic liver resection (LLR), robotic liver resection (RLR), or a combination of these, were included. To explore quantitatively the learning curve for MIH, a meta-regression analysis was performed. RESULTS Forty studies relating to learning curves in MIH were included. The median overall number of procedures required in studies utilizing cumulative summative (CUSUM) methodology for LLR was 50 (range 25-58) and for RLR was 25 (16-50). After adjustment for year of adoption of MIH, the CUSUM-derived caseload to surmount the learning curve for RLR was 47.1 (95 per cent c.i. 1.2 to 71.6) per cent; P = 0.046) less than that required for LLR. A year-on-year reduction in the number of procedures needed for MIH was observed, commencing at 48.3 cases in 1995 and decreasing to 23.8 cases in 2015. CONCLUSION The overall learning curve for MIH decreased steadily over time, and appeared less steep for RLR compared with LLR.

Abstract
In living donor liver transplantation (LDLT) the safety of the live donor (LD) is of paramount importance. Despite all efforts, the morbidity rates approach 25%-40% with conventional open donor hepatectomy (DH) operations. However, most of these complications are related to the operative wound and despite increased self- esteem and satisfaction in various quality of life analyses on LD, the most common grievance is that of the scar. Performing safe and precise DH through a conventional laparoscopic approach is a formidable task with a precipitous learning curve for the whole team. Due to the ramifications the donor operation carries for the donor, the recipient, the transplant team and for the LDLT program in general, the development and acceptance of minimally invasive DH (MIDH) has been slow. The robotic surgical system overcomes the reduced visualization, restricted range of motion and physiological tremor associated with laparoscopic surgery and allows for a comparatively easier transition from technical feasibility to reproducibility. However, many questions especially with regards to standardization of surgical technique, comparison of outcomes, understanding of the learning curve, etc. remain unanswered. The aim of this review is to provide insights into the evolution of MIDH and highlight the current status of robotic DH, appreciating the existing challenges and its future role.

Abstract
BACKGROUND AND AIM Favorable outcomes of laparoscopic hepatectomy (LH) over open hepatectomy (OH) have been demonstrated. LH offers less postoperative morbidity, less blood loss, and shorter hospital stay, while maintaining oncological safety. Only limited evidence about outcomes of LH in elderly is currently available. Therefore, this study aimed to compare short term outcomes of LH to OH for patients >65 years. METHODS A systematic review and meta-analysis were performed according to Cochrane guidelines. Embase, PubMed, Cochrane Library, and Google Scholar were searched to identify eligible studies. Studies were included if they compared LH to OH, and focused on an elderly population, or had a majority of patients >65 years. Perioperative and postoperative outcomes were analyzed. RESULTS Thirteen studies with 1174 patients (LH:532, OH:642) were included for analysis. When compared to OH, elderly undergoing LH had significantly less postoperative complications (risk ratio [RR]0.52; 95% confidence interval (CI):0.43-0.63), less blood loss (mean difference [MD]-198.58; 95% CI:-299.88 to -97.28), and shorter length of stay (MD-4.83; 95%CI:-7.91 to -1.84), while oncological safety was non-inferior (RR1.04; 95%CI:1.00-1.08). CONCLUSIONS Within the elderly population LH seems to be superior to OH, concerning short-term outcomes. However, for broader applicability more trials are needed including more difficult and major resections.

Abstract
OBJECTIVE To compare the safety and short-term outcomes between robotic-assisted and laparoscopic left hemi-hepatectomies in a single academic medical center. METHODS A cohort of 52 patients, who underwent robotic-assisted or laparoscopic left hemi-hepatectomies between April 2015 and January 2020 in Department of Pancreatobiliary Surgery, the First Affiliated Hospital of Sun Yat-Sen University was recruited into the study. Their clinicopathological features and short-term outcomes were analyzed retrospectively. RESULTS There were 25 robotic-assisted and 27 laparoscopic cases, with a median age of 55 years (34-77 years). There was one conversion to open in laparoscopic group. There were no significant differences in clinicopathological features between two groups, except robotic group had higher body mass index (23.9 vs. 22.0 kg/m2, p = 0.047). Robotic-assisted and laparoscopic groups had similar operative time (300 vs. 310 min, p = 0.515), length of hospital stay (8 vs. 8 days, p = 0.981) and complication rates (4.0% vs. 14.8%, p = 0.395), but the former had less blood loss (100 vs. 200 ml, p < 0.001) and lower incidence of blood transfusion (0% vs. 22.2%, p = 0.023) in comparison with laparoscopic group. R0 resection was achieved for all patients with malignancies. There was no perioperative mortality in both groups. The cost of robotic group was higher than laparoscopic group (105,870 vs. 64,191 RMB yuan, p = 0.02). CONCLUSION The robotic-assisted and laparoscopic approaches had similar safety and short-term outcomes in left hemi-hepatectomy, and the former can reduce operative blood loss and blood transfusion. However, the costs were higher in robotic group.

Abstract
BACKGROUND LLR is widely adapted for HCC, while LLR in PS segments is still challenging. With recent improvement of techniques and accumulation of experiences, LLR in PS segments is feasible, but studies investigating the result after the modifications are lacking. METHODS In this single-center, retrospective study, 149 patients who underwent LLR for HCC located in PS segments from September 2003 to December 2016 were analyzed. The patients were divided into Group 1 (n=43) and Group 2 (n=106) who underwent LLR before and after 2012, respectively, when advanced techniques including use of intercostal trocars, Pringle maneuver, and semi-lateral position of patient were introduced. Also, these patients were compared with those who underwent open liver resection (OLR; n=124) for HCC in PS segments during the same period. RESULTS Mean operative time (394.7 minutes vs 331.2 minutes; P=0.013), intraoperative blood loss (1545.8 ml vs 1208.2 ml; P=0.020), and hospital stay (11.6 days vs 9.2, P<0.001) were significantly less in Group 2. Postoperative complication rate (18.6% vs 18.9%; P=0.970), open conversion rate (23% vs 17%; P=0.374), 5-year overall (79% vs 89%; P=0.607) and 5-year disease-free (52% vs 53%; P=0.657) survival rates were not significantly different between the groups. Compared to the OLR group, complication rate (40.3% vs 18.8%; P< 0.001) and hospital stay (17.6 days vs 9.7 days; P< 0.001) were significantly lower in the LLR group. CONCLUSION The complexity of LLR for HCC in PS segments is being gradually overcome by the introduction of advanced techniques.

Minimally invasive versus open right hepatectomy: comparative study with propensity score matching analysis. BMC Surg 2020; 20:260.

Abstract
BACKGROUND Minimally invasive liver resections (MILRs) have been increasingly performed in recent years. However, the majority of MILRs are actually minor or limited resections of peripheral lesions. Due to the technical complexity major hepatectomies remain challenging for minimally invasive surgery. The aim of this study was to compare the short and long-term outcomes of patients undergoing minimally invasive right hepatectomies (MIRHs) with contemporary patients undergoing open right hepatectomies (ORHs) METHODS: Consecutive patients submitted to anatomic right hepatectomies between January 2013 and December 2018 in two tertiary referral centers were studied. Study groups were compared on an intention-to-treat basis after propensity score matching (PSM). Overall survival (OS) analyses were performed for the entire cohort and specific etiologies subgroups RESULTS: During study period 178 right hepatectomies were performed. After matching, 37 patients were included in MIRH group and 60 in ORH group. The groups were homogenous for all baseline characteristics. MIRHs had significant lower blood loss (400 ml vs. 500 ml, P = 0.01), lower rate of minor complications (13.5% vs. 35%, P = 0.03) and larger resection margins (10 mm vs. 5 mm, P = 0.03) when compared to ORHs. Additionally, a non-significant decrease in hospital stay (ORH 9 days vs. MIRH 7 days, P = 0.09) was observed. No differences regarding the use of Pringle's maneuver, operative time, overall morbidity or perioperative mortality were observed. OS was similar between the groups (P = 0.13). Similarly, no difference in OS was found in subgroups of patients with primary liver tumors (P = 0.09) and liver metastasis (P = 0.80). CONCLUSIONS MIRHs are feasible and safe in experienced hands. Minimally invasive approach was associated with less blood loss, a significant reduction in minor perioperative complications, and did not negatively affect long-term outcomes.

Abstract
Aims. Minimally invasive liver resection is a complex and challenging operation. Although authors have reported robotic liver resection shows improved safety and efficacy compared with open liver resection, robotic major liver resections for malignant liver lesions treatment remain inadequately evaluated. The aims of the present study were to evaluate the feasibility and safety of transitioning from open to robotic liver resection in a nonuniversity hospital. Patients and Methods. From December 2015 to March 2020, 46 patients underwent totally robotic-assisted liver resections out of 446 robotic procedures. Also, we retrospectively reviewed the last 27 open right hepatectomies (ORHs) and compared then with the first 25 anatomic robotic-assisted right hepatectomies (RRHs). Results. Mean operative time, mean blood lost, rate of complications, and mean hospital stay were associated with the complexity of the procedure. The comparison between ORH and RRH showed that intraoperative complications were less frequently observed during ORH whereas RRH showed a trend in favor of less blood loss. ORH had a trend toward smaller surgical margins and higher rate of R1 resections. Recurrence occurred in 31 (59%) patients and was more frequently observed after ORH. However, the mean follow-up was significantly shorter after RRH. Conclusion. Our study demonstrated the technical feasibility and safety of transitioning from open to robotic liver resection (including major hepatectomies) in a nonuniversity setting. Higher costs remain an important drawback for robotic surgery.

Learning Curve in Laparoscopic Liver Resection, Educational Value of Simulation and Training Programmes: A Systematic Review. World J Surg 2020; 43:2710-2719.

Abstract
BACKGROUND The laparoscopic approach is widely accepted as the procedure of choice for abdominal surgery. However, laparoscopic liver resection (LLR) has advanced slowly due to the significant learning curve (LC), and only few publications have dealt with advanced training in LLR. METHODS Two reviewers conducted systematic research through MEDLINE and EMBASE with combinations of the following keywords: (learning curve OR teaching OR training OR simulation OR education) AND (liver OR hepatic) AND (laparoscopic OR laparoscopy). Robotic-assisted, hand-assisted and hybrid LLRs were excluded. RESULTS Nineteen studies were retrieved. Overall, the level of evidence was low. Thirteen articles assessed the LC during real-life LLR, and six articles focussed on simulation and training programmes in LLR. The LC in minor LLR comprised 60 cases overall, and 15 cases for standardised left lateral sectionectomy. For major LLR (MLLR), the LC was 50 cases for most studies, but was reported to be 15-20 cases in more recent studies, provided MLLR is performed progressively in selected patients. However, there was heterogeneity in the literature regarding the number of minor LLRs required before MLLR, with 60 minor LLRs reported as the minimum. Six studies showed a potential benefit of simulation and training programmes in this field. The gradual implementation of LLR combined with simulation-based training programmes could reduce the clinical impact of LC. CONCLUSIONS The LC in LLR is a long process, and MLLR should be gradually implemented under the supervision of experienced surgeons. Training outside the operating room may reduce the LC in real-life situations.

Abstract
BACKGROUND Neonatal-perinatal medicine (NPM) fellowship programs must provide adequate delivery room (DR) experience to ensure that physicians can independently provide neonatal resuscitation to very low birth weight (VLBW) infants. The availability of learning opportunities is unknown. METHODS The number of VLBW (≤1500 g) and extremely low birth weight (ELBW) (<1000 g) deliveries, uses of continuous positive airway pressure, intubation, chest compressions, and epinephrine over 3 years at accredited civilian NPM fellowship program delivery hospitals were determined from the Vermont Oxford Network from 2012 to 2017. Using Poisson distributions, we estimated the expected probabilities of fellows experiencing a given number of cases over 3 years at each program. RESULTS Of the 94 NPM fellowships, 86 programs with 115 delivery hospitals and 62 699 VLBW deliveries (28 703 ELBW) were included. During a 3-year fellowship, the mean number of deliveries per fellow ranged from 14 to 214 (median: 60) for VLBWs and 7 to 107 (median: 27) for ELBWs. One-half of fellows were expected to see ≤23 ELBW deliveries and 52 VLBW deliveries, 24 instances of continuous positive airway pressure, 23 intubations, 2 instances of chest compressions, and 1 treatment with epinephrine. CONCLUSIONS The number of opportunities available to fellows for managing VLBW and ELBW infants in the DR is highly variable among programs. Fellows' exposure to key, high-risk DR procedures such as cardiopulmonary resuscitation is low at all programs. Fellowship programs should track fellow exposure to neonatal resuscitations in the DR and integrate supplemental learning opportunities. Given the low numbers, the number of new and existing NPM programs should be considered.

Abstract
Laparoscopic liver resection is a demanding procedure that is undergoing continuous development. The surgeon's skill is constantly improving, new surgical instruments are being introduced, and the indications for this procedure are expanding. However, there is still great concern about patient safety during the procedure and it is not commonly performed in many centers, although numerous studies have confirmed the safety and feasibility of laparoscopic liver techniques. Our center tries to use laparoscopy routinely for most cases and we do not consider conversion to open surgery to be a complication. We present our current opinion on patient selection for laparoscopic liver resection in the hope of encouraging more centers to adopt and develop this technique. Although laparoscopic liver resection is not an official standard of care, it should be considered according to the surgeon's experience and available resources.

Abstract
BACKGROUND Laparoscopic major hepatectomy is a technically challenging procedure requiring a steep learning curve. The liver hanging maneuver is a useful technique in liver resection, especially for large or invasive tumors, a relative contraindication of the laparoscopic approach. Therefore, this study aimed to evaluate the learning curve for laparoscopic major hepatectomy using the liver hanging maneuver and extended indications. METHODS Patients who underwent laparoscopic major hepatectomy using the liver hanging maneuver by a single surgeon from January 2013 and September 2018 were retrospectively reviewed. Our hanging technique involves placing the hanging tape along the inferior vena cava for right-sided hepatectomy or the ligamentum venosum for left-sided hepatectomy. The upper end of the tape was placed at the lateral side of the major hepatic veins. The learning curve for operating time and blood loss was evaluated using the cumulative sum (CUSUM) method. RESULTS Among 53 patients, 18 underwent right hepatectomy, 26 underwent left hepatectomy, and 9 underwent right posterior sectionectomy. CUSUM analysis showed that operative time and blood loss improved after the 30th laparoscopic major hepatectomy. The 53 consecutive patients were divided into two groups (early, patients 1-30; late, patients 31-53). The median operative time was lower in the late group, but the difference was not statistically significant (270 vs. 245 min, p = 0.261). The median blood loss was also significantly lower in the late group (350 vs. 150 ml, p < 0.001). Large tumors (measuring > 10 cm) and tumors in proximity to major vessels were significantly higher in the late group (0 vs. 17.4%, p = 0.018; 3.3 vs. 21.7%, p = 0.036; respectively). CONCLUSION This study shows that laparoscopic major hepatectomy using the modified liver hanging maneuver has a learning curve of 30 cases. After procedure standardization, the indications have gradually been extended to large or invasive tumors.

Abstract
The application of the minimally invasive approach has shown to be safe and effective for liver surgery and is in constant growth. The indications for laparoscopic surgery are steadily increasing across the field. In the early 2000s, robotic surgery led to some additional improvements, such as tremor filtration, instrument stability, 3D view and more comfort for the surgeon. These techniques bring in some advantages compared to the traditional OLR: less blood loss, shorter admissions, fewer adhesions, and a faster postoperative recovery and better outcomes in case of further hepatectomy for tumor recurrence has been shown. Concerning which is the best minimally invasive approach between laparoscopic and robotic surgery, the evidence is still conflicting. The latter shows good potential, since the endo-wristed instruments work similarly to the surgeon's hands, even with an intact abdominal wall. However, the technique is still under development, burdened by important costs, and limited by the lack of some instruments available for the laparoscopic approach. The paucity of universally accepted and proven data, especially concerning long-term outcomes, hampers drawing univocal acceptance at present. Furthermore, the number of variables related both to the patient and the disease further complicates the decision leading to a treatment tailored to each patient with strict selection. This review aims to explore the main differences between laparoscopic and robotic surgery, focusing on indications, operative technique and current debated clinical issues in recent literature.

Abstract
BACKGROUND Laparoscopic liver resection demands expertise and a long learning curve. Resection of the posterosuperior segments is challenging, and there are no data on the learning curve. The aim of this study was to evaluate the learning curve for laparoscopic resection of the posterosuperior segments. METHODS A cumulative sum (CUSUM) analysis of the difficulty score for resection was undertaken using patient data from four specialized centres. Risk-adjusted CUSUM analysis of duration of operation, blood loss and conversions was performed, adjusting for the difficulty score of the procedures. A receiver operating characteristic (ROC) curve was used to identify the completion of the learning curve. RESULTS According to the CUSUM analysis of 464 patients, the learning curve showed an initial decrease in the difficulty score followed by an increase and, finally, stabilization. More patients with cirrhosis or previous surgery were operated in the latest phase of the learning curve. A smaller number of wedge resections and a larger number of anatomical resections were performed progressively. Dissection using a Cavitron ultrasonic surgical aspirator and the Pringle manoeuvre were used more frequently with time. Risk-adjusted CUSUM analysis showed a progressive decrease in operating time. Blood loss initially increased slightly, then stabilized and finally decreased over time. A similar trend was found for conversions. The learning curve was estimated to be 40 procedures for wedge and 65 for anatomical resections. CONCLUSION The learning curve for laparoscopic liver resection of the posterosuperior segments consists of a stepwise process, during which accurate patient selection is key.

Abstract
There are diverse approaches to parenchymal transection and the preferred approach remains controversial among liver surgeons. Stapling devices, which were initially established for vascular control, have been the standard parenchymal transection technique in many departments for more than 15 years. This article describes the technical aspects, tips, and tricks of stapled hepatectomy using right hemihepatectomy as an example. The existing literature on this topic is also reviewed.

Abstract
BACKGROUND Laparoscopic liver resection (LLR) of posterosuperior (PS) segment liver tumors is technically challenging with confusion about optimal patient positioning and trocar placement (i.e., transabdominal vs. transcostal). The aim of this study is to describe our technique and outcomes with LLR of these tumors. METHODS This is an IRB-approved retrospective review of a prospective database. Between 2005 and 2017, patients with benign and malignant lesions underwent LLR. Perioperative outcomes of PS (segments 4A, 7, and 8) and anterolateral (AL) resections were compared. All patients were operated through intra-abdominal trocars in the supine position. RESULTS 304 patients underwent LLR for AL (n = 217) and PS (n = 87) segmental lesions. Minor liver resections were performed in 274 patients and major resections in 30. Groups were comparable for age, sex, pathology, and tumor size (mean 4.2 and 3.7 cm for AL and PS). Inflow occlusion was more frequently performed for PS resections, but precoagulation rates were similar. PS resections more frequently required hand assistance (50% vs. 20%, p < 0.001) and conversion to open (18% vs. 7%, p = 0.04). For PS versus AL resections, operative time (253 vs. 205 min, p ≤ 0.001) was longer and associated with more blood loss (307 vs. 211 mL, p < 0.001) and more frequent need for blood transfusion (15% vs. 7%, p = 0.04). However, the rate of negative resection margin, 90-day complication rates, and length of stay were similar between the two groups. CONCLUSION This study shows that LLR of PS located liver tumors is more challenging compared to AL lesions. Nevertheless, it can be performed successfully in the majority of patients with supine positioning and intra-abdominal trocar placement, without compromising oncologic principles. Liberal uses of hand assistance and inflow occlusion were the technical tips helping us to successfully resect these tumors laparoscopically.

Laparoscopic vs. open left lateral sectionectomy: An update meta-analysis of randomized and non-randomized controlled trials. Int J Surg 2018; 61:1-10. [PMID: 30496866 DOI: 10.1016/j.ijsu.2018.11.021] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2018] [Revised: 09/28/2018] [Accepted: 11/14/2018] [Indexed: 02/06/2023]
Abstract
BACKGROUND Left lateral sectionectomy (LLS) is thought to be the anatomical liver resection most suitable for the laparoscopic approach. Despite increasing popularity, comparative analysis of laparoscopic and open LLS are mostly limited to retrospective, underpowered studies with small sample size. Recent population-based studies and prospective trials have generated new data; however, this new body of knowledge has not been submitted systematic reviews or meta-analyses and high quality evidence regarding the actual benefits of minimally invasive LLS is lacking. METHODS Systematic review of studies published until December 31st, 2017 and indexed in Medline, EMBASE, Cochrane Library Central and Scielo/LILACS databases. Randomized controlled trials and observational studies comparing perioperative results of laparoscopic and open LLS were included. Studies with patients submitted to LLS for living donation were excluded. Treatment outcomes, including conversion rates, estimated blood loss, transfusion rates, operative time, length of in-hospital stay, morbidity and mortality rates, were evaluated. RESULTS The primary search yielded 2838 articles, 23 of which (21 observational studies and 2 randomized controlled trials; 3415 patients) were included in the meta-analysis. Overall conversion rate was 7.4%. Patients submitted to laparoscopic LLS had less blood loss (mean difference, MD = -119.81 ml, 95% CI = -127.90, -111.72, P < .00001, I2 = 32%, N = 618), lower transfusion rates (4.1% vs. 10.1%; risk difference, RD = - 0.06, 95% CI = - 0.08, - 0.05, P < .00001, I2 = 13%, N = 2968) and shorter length of in-hospital stay (MD = - 2.02 days, 95% CI = - 2.15, - 1.89, P < .00001, I2 = 77%, N = 3160) compared to those undergoing open surgery. Marginally decreased overall complication (21.4% vs. 27.5%; RD = - 0.03, 95% CI = - 0.06, 0.00, P = .05, I2 = 0%, N = 3268) and perioperative mortality (0.3% vs. 1.5%; RD = - 0.01, 95% CI = - 0.02, - 0.00, P = .01, I2 = 0%; N = 3332) rates were also observed. Operative time and biliary, cardiac or pulmonary complication rates did not differ significantly between groups. CONCLUSION Current evidence supports the safety and feasibility of laparoscopic LLS. The laparoscopic approach is associated with reduced blood loss, lower transfusion rates and shorter length of in-hospital stay and should be considered the gold-standard for LLS.

Abstract
Abstract
Background
Previous studies have demonstrated that patient, surgical, tumour and operative variables affect the complexity of laparoscopic liver resections. However, current difficulty scoring systems address only tumour factors. The aim of this study was to develop and validate a predictive model for the risk of intraoperative complications during laparoscopic liver resections.
Methods
The prospectively maintained databases of seven European tertiary referral liver centres were compiled. Data from two-thirds of the patients were used for development and one-third for validation of the model. Intraoperative complications were based on a modified Satava classification. Using the methodology of the Framingham Heart Study, developed to identify risk factors that contribute to the development of cardiovascular disease, factors found to predict intraoperative complications independently were assigned points, and grouped into low-, moderate-, high- and extremely high-risk groups based on the likelihood of intraoperative complications.
Results
A total of 2856 patients were included. Neoadjuvant chemotherapy, lesion type and size, classification of resection and previous open liver resection were found to be independent predictors of intraoperative complications. Patients with intraoperative complications had a longer duration of hospital stay (5 versus 4 days; P < 0·001), higher complication rates (32·5 versus 15·5 per cent; P < 0·001), and higher 30-day (3·0 versus 0·3 per cent; P < 0·001) and 90-day (3·8 versus 0·8 per cent; P < 0·001) mortality rates than those who did not. The model was able to predict intraoperative complications (area under the receiver operating characteristic (ROC) curve (AUC) 0·677, 95 per cent c.i. 0·647 to 0·706) as well as postoperative 90-day mortality (AUC 0·769, 0·681 to 0·858).
Conclusion
This comprehensive scoring system, based on patient, surgical and tumour factors, and developed and validated using a large multicentre European database, helped estimate the risk of intraoperative complications.

Abstract
Currently the majority of liver resections are performed via open resection. Nevertheless, minimally invasive liver surgery is gaining ground and conventional laparoscopy has proven to be beneficial in different fields of liver surgery compared to open resections. Still, conventional laparoscopy has a few downsides, from which straight instruments, 2-dimensional view and awkward ergonomics are the most obvious. The robotic surgical system is developed to overcome these limitations. It offers several advantages over conventional laparoscopy to optimize conditions in minimally invasive surgery: instruments are wristed with a wide range of motion and the view is 3-dimensional and magnified. With instruments with a greater range of motion than in laparoscopic surgery, the use of a robotic system potentially broadens indications for minimally invasive liver resection. Here, we discuss the steps of setting up a robotic hepatectomy program against the background of the initial experience at our institution.

Abstract
The introduction of robotic surgical systems has revolutionized the practice of minimal invasive surgery (MIS). Although little data regarding robotic hepatectomies have been reported, it appears to be similar to conventional laparoscopic approach in terms of blood loss, morbidity rate, mortality rate and hospital stay at least. The application of robotic system in liver surgery was not well evaluated yet, particularly learning curve. Studies were identified by searching MEDLINE and PubMed databases for articles from January 2001 to May 2016 using the keywords "laparoscopic hepatectomy", "robotic hepatectomy", and "learning curve". With the limited data in robotic hepatectomy, the learning curve model of robotic hepatectomy needs to base on the experience of conventional laparoscopic hepatectomy. Based on the learning curve study experience for laparoscopic hepatectomies, the minimal number laparoscopic minor and major hepatectomies to overcome learning curve are 22-64 cases, and 45-75 cases, respectively. Left lateral sectionectomy technique is more standardized, and it is a good start for training of MIS liver surgery. However, the training program required for the robotic liver surgeons still highly depends on the surgeons' experience of previous open and laparoscopic liver surgery, the surgeons' previous experience of other robotic surgeries, the experience of the surgical team including the assistant surgeons and nursing staffs, and the complexity of the diseases. We discourage performance of robotic hepatectomy in the occasional patient by a team that is not well prepared and is not embedded in a specialized center. Knowledge and practical skills are both required in MIS liver surgery and cannot be replaced by newer tools, including the most advanced robotic system.

Abstract
BACKGROUND Robotic hepatectomy has been suggested as a safe and effective management of liver disease. However, no large case series have documented the learning curve for robotic major hepatectomy. METHOD We conducted a retrospective study for robotic major hepatectomy performed by the same operative team between January 2012 and October 2015 and evaluated the learning curve for operation time using the cumulative sum method, presented as cumulative sumoperation time. RESULTS Overall, there were 183 robotic hepatectomies, 92 of which were performed in patients who underwent robotic major hepatectomy: left hemihepatectomy was performed in 32 (34.8%) patients, right hemihepatectomy in 41 (44.6%), left trisectionectomy in 3 (3.3%), right trisectionectomy in 6 (6.5%), and 8-5-4 trisegmentectomy in 10 (10.8%). The median duration of surgery was 434 minutes (142-805 minutes) and the median blood loss was 195 mL (50-2,000 mL). Fifty-nine percent of patients had malignancies, and those with advanced stages of cancer had more blood loss during an operation. The cumulative sumoperation time model of robotic major hepatectomy suggested that the learning curve comprised 3 characteristic phases: initial (phase 1, 15 patients), intermediate (phase 2, 25 patients), and mature (phase 3, 52 patients). The learning effects were underlined by shorter operation time and hospital stay after phase 1 and less blood loss after phase 2. CONCLUSION This is the largest series regarding robotic major hepatectomy. Our findings suggest that a solid training program based on the learning curve should be considered for beginners of robotic hepatectomy. Participants should evaluate the evolution of our minimally invasive hepatectomy before considering our robotic experience.

Abstract
BACKGROUND Laparoscopic liver resection is an attractive option for treating liver tumors. Laparoscopic liver resection is more difficult for hepatocellular carcinomas located in the posterosuperior segments than for hepatocellular carcinomas in the anterolateral segments. We compared perioperative and long-term outcomes between laparoscopic liver resection for hepatocellular carcinomas located in the posterosuperior and anterolateral segments. METHODS We retrospectively reviewed the clinical data for 230 patients who underwent laparoscopic liver resection for hepatocellular carcinomas between September 2003 and July 2014. Of these, 116 patients were selected by case-matched analysis using age, sex, tumor number and size, Child-Pugh class, and extent of liver resection. Patients were classified into 2 groups according to tumor location: the anterolateral group (n = 58) and the posterosuperior group (n = 58). RESULTS Operation time (355 minutes vs 212 minutes, P < .005), intraoperative blood loss (600 mL vs 410 mL, P < .001), and hospital stay (8.5 days vs 7 days, P = .040) were significantly greater in the posterosuperior group than in the anterolateral group. The open conversion (13.8% vs 10.3%, P = .777), postoperative complication (17.2% vs 10.3%, P = .420), 5-year overall survival (88.5% vs 85.7%, P = .370), and 5-year, recurrence-free survival (47.6% vs 40.9%, P = .678) rates were not significantly different between the posterosuperior and anterolateral groups. CONCLUSION Although laparoscopic liver resection is more difficult for hepatocellular carcinomas located in the posterosuperior segment, there were no differences in the short- and long-term outcomes between the posterosuperior and anterolateral groups. The perceived impact of tumor location on patient outcomes could be overcome by experience and technical improvements.
