Comparative cost-effectiveness of open, laparoscopic, and robotic liver resection: A systematic review and network meta-analysis. Surgery 2024; 176:11-23. [PMID: 38782702 DOI: 10.1016/j.surg.2024.04.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Revised: 03/25/2024] [Accepted: 04/11/2024] [Indexed: 05/25/2024]
Abstract
BACKGROUND This study evaluated the cost-effectiveness of open, laparoscopic, and robotic liver resection. METHODS A comprehensive literature review and Bayesian network meta-analysis were conducted. Surface under cumulative ranking area values, mean difference, odds ratio, and 95% credible intervals were calculated for all outcomes. Cluster analysis was performed to determine the most cost-effective clustering approach. Costs-morbidity, costs-mortality, and costs-efficacy were the primary outcomes assessed, with postoperative overall morbidity, mortality, and length of stay associated with total costs for open, laparoscopic, and robotic liver resection. RESULTS Laparoscopic liver resection incurred the lowest total costs (laparoscopic liver resection versus open liver resection: mean difference -2,529.84, 95% credible intervals -4,192.69 to -884.83; laparoscopic liver resection versus robotic liver resection: mean difference -3,363.37, 95% credible intervals -5,629.24 to -1,119.38). Open liver resection had the lowest procedural costs but incurred the highest hospitalization costs compared to laparoscopic liver resection and robotic liver resection. Conversely, robotic liver resection had the highest total and procedural costs but the lowest hospitalization costs. Robotic liver resection and laparoscopic liver resection had a significantly reduced length of stay than open liver resection and showed less postoperative morbidity. Laparoscopic liver resection resulted in the lowest readmission and liver-specific complication rates. Laparoscopic liver resection and robotic liver resection demonstrated advantages in costs-morbidity efficiency. While robotic liver resection offered notable benefits in mortality and length of stay, these were balanced against its highest total costs, presenting a nuanced trade-off in the costs-mortality and costs-efficacy analyses. CONCLUSION Laparoscopic liver resection represents a more cost-effective option for hepatectomy with superior postoperative outcomes and shorter length of stay than open liver resection. Robotic liver resection, though costlier than laparoscopic liver resection, along with laparoscopic liver resection, consistently exceeds open liver resection in surgical performance.

Abstract
PURPOSE This study evaluated the accuracy of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) calculator in predicting outcomes after hepatectomy for colorectal cancer (CRC) liver metastasis in a Southeast Asian population. METHODS Predicted and actual outcomes were compared for 166 patients undergoing hepatectomy for CRC liver metastasis identified between 2017 and 2022, using receiver operating characteristic curves with area under the curve (AUC) and Brier score. RESULTS The ACS-NSQIP calculator accurately predicted most postoperative complications (AUC > 0.70), except for surgical site infection (AUC = 0.678, Brier score = 0.045). It also exhibited satisfactory performance for readmission (AUC = 0.818, Brier score = 0.011), reoperation (AUC = 0.945, Brier score = 0.002), and length of stay (LOS, AUC = 0.909). The predicted LOS was close to the actual LOS (5.9 vs. 5.0 days, P = 0.985). CONCLUSION The ACS-NSQIP calculator demonstrated generally accurate predictions for 30-day postoperative outcomes after hepatectomy for CRC liver metastasis in our patient population.

Abstract
BACKGROUND Laparoscopic-assisted (LALR) and hand-assisted (HALR) liver resections have been utilized during the early adoption phase by surgeons when transitioning from open surgery to pure LLR. To date, there are limited data reporting on the outcomes of LALR or HALR compared to LLR. The objective was to compare the perioperative outcomes after LALR and HALR versus pure LLR. METHODS This is an international multicentric analysis of 6609 patients undergoing minimal-invasive liver resection at 21 centers between 2004 and 2019. Perioperative outcomes were analyzed after propensity score matching (PSM) comparison between LALR and HALR versus LLR. RESULTS 5279 cases met study criteria of whom 5033 underwent LLR (95.3%), 146 underwent LALR (2.8%) and 100 underwent HALR (1.9%). After 1:4 PSM, LALR was associated with inferior outcomes as evidenced by the longer postoperative stay, higher readmission rate, higher major morbidity rate and higher in-hospital mortality rate. Similarly, 1:6 PSM comparison between HALR and LLR also demonstrated poorer outcomes associated with HALR as demonstrated by the higher open conversion rate and higher blood transfusion rate. All 3 approaches technical variants demonstrated the same oncological radicality (R1 rate). CONCLUSION LALR and HALR performed during the learning curve was associated with inferior perioperative outcomes compared to pure LLR.

Intraoperative blood transfusion does not impact overall and recurrence-free survival after curative hepatectomy for hepatocellular carcinoma: A propensity-score-matched and inverse probability of treatment-weighted study. J Surg Oncol 2023; 127:598-606.

Abstract
INTRODUCTION Our primary objective was to determine if receiving intraoperative blood transfusion was a significant prognostic factor for overall and recurrence-free survival after curative resection of hepatic cellular carcinoma (HCC). METHODOLOGY Between 2001 and 2018, 1092 patients with histologically proven primary HCC who underwent curative liver resection were retrospectively reviewed. Primary study endpoints were recurrence-free survival (RFS) and overall survival (OS). The main analysis was undertaken using propensity-score matching (PSM) to minimize confounding and selection biases in the comparison of patients with or without transfusion. RESULTS There were 220 patients who received and 666 patients who did not receive intraoperative blood transfusion. The PSM cohort consisted of 163 pairs of patients. After PSM, the only perioperative outcome that appeared to significantly affect whether patients would receive blood transfusion was median blood loss (p = 0.001). In the PSM cohort, whether patients received blood transfusion was neither associated with OS (p = 0.759) nor RFS (p = 0.830). When the volume of blood transfusion was analyzed as a continuous variable, no significant dose-response relationship between blood transfusion volume and HR for OS and RFS was noted. CONCLUSION Intraoperative blood transfusion had no significant impact on the survival outcomes in patients who receive curative resection in primary HCC.

Abstract
BACKGROUND The majority of evidence with regards to minimally invasive liver resection (MILR) favors its application in minor hepatectomies. We conducted a propensity score-matched (PSM) analysis to determine its feasibility and safety in major hepatectomies (MIMH) for liver malignancies. METHODS Retrospective review of 130 patients who underwent MIMH and 490 patients who underwent open major hepatectomy (OMH) for malignant pathologies was performed. PSM in a 1:1 ratio identified two groups of patients with similar baseline clinicopathological characteristics. Perioperative outcomes were then compared. Major hepatectomies included traditional major (>3 segments) and technical major hepatectomies (right anterior and right posterior sectionectomies). RESULTS Both cohorts were well-matched for baseline characteristics after PSM. Of 130 MIMH cases, there were 12 conversions to open. Comparison of perioperative outcomes demonstrated a significant association of MIMH with longer operation time and more frequent application of Pringle's maneuver (PM), but decreased postoperative stay. These results were consistent on a subgroup analysis that only included patients undergoing traditional major hepatectomies. A second subgroup analysis restricted to cirrhotic patients demonstrated that while perioperative outcomes were equivalent, MIMH was similarly associated with a longer operative time. Subset analyses of resections performed after 2015 demonstrated that MIMH was additionally associated with a lower postoperative morbidity compared to OMH. CONCLUSION Comparison of perioperative and short-term oncological outcomes between MIMH and OMH for malignancies demonstrated that MIMH is feasible and safe. It is associated with a shorter hospital stay at the expense of a longer operation time compared to OMH.

Abstract
Background: Minimally invasive pancreatic pancreatoduodenectomy (MIPD) is increasingly adopted worldwide and its potential advantages include reduced hospital stay and decrease pain. However, evidence supporting the role of MIPD for tumours requiring vascular reconstruction remains limited and requires further evaluation. This study aims to investigate the safety and efficacy of MIPD with vascular resection (MIPDV) by performing a 1:1 propensity-score matched (PSM) comparison with open pancreatoduodenectomy with vascular resection (OPDV) based on a single surgeon's experience. Methods: This is a retrospective review of 41 patients who underwent PDV between 2011 and 2020 by a single surgeon. After PSM, the comparison was made between 13 MIPDV and 13 OPDV. Results: Thirty-six patients underwent venous reconstruction (VR) only and 5 underwent arterial reconstruction of which 4 had concomitant VR. The types of VR included 22 wedge resections with primary repair, 8 segmental resections with primary anastomosis and 11 requiring interposition grafts. Post-operative pancreatic fistula (POPF) occurred in 3 (7.3%) patients. Major complications (>Grade 2) occurred in 16 (39%) patients, of which 7 were due to delayed gastric emptying requiring nasojejunal tube placement. There was 1 (2.4%) 30-day mortality (OPDV). Of the 13 MIPDV, there were 3 (23.1%) open conversions. PSM comparison demonstrated that MIPDV was associated with longer median operative time (720 min vs. 485 min (P = 0.018). There was no statistically significant difference in other key perioperative outcomes such as intra-operative blood loss, overall morbidity, major morbidity rate, POPF and length of stay. Conclusion: Our initial experience with the adoption MIPDV has demonstrated it to be safe with comparable outcomes to OPDV despite the longer operation time.

Effect of age on the short- and long-term outcomes of patients undergoing curative liver resection for HCC. Eur J Surg Oncol 2021; 48:1339-1347. [PMID: 34972621 DOI: 10.1016/j.ejso.2021.12.027] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2021] [Revised: 11/17/2021] [Accepted: 12/21/2021] [Indexed: 02/09/2023] Open
Abstract
BACKGROUND Few studies have evaluated the outcomes of curative liver resection (LR) in octogenarian patients, analysed cancer-specific survival (CSS) with HCC-related death or explored the age-varying effect of HCC-related death in elderly patients undergoing LR. We aim to determine the effect of age on the short and long-term outcomes of LR for HCC. METHODOLOGY Between 2000 and 2018, 1,092 patients with primary HCC who underwent LR with curative intent were retrospectively reviewed. The log-rank test and Gray's test were used to assess the equality of survivor functions and competing risk-adjusted cumulative incidence functions between patients in the three age categories respectively. Regression adjustment was used to control for confounding bias via a Principal Component Analysis. Quantile, Firth logistic, Cox, and Fine-Gray competing risk regression were used to analyse continuous, binary, time-to-event, and cause-specific survival respectively. Restricted cubic splines were used to illustrate the dose-effect relationship between age and patient outcomes. RESULTS The study comprised of 764 young patients (<70 years), 278 septuagenarians (70-79 years old) and 50 octogenarians (≥80 years). Compared to young patients, octogenarians had significantly lower 5-year OS(62.1% vs 37.7%, p < 0.001). However, there was no significant difference in 1-year RFS(73.1% vs 67.0%, p = 0.774) or 5-year CSS (5.4% vs 15.2%, p = 0.674). Every 10-year increase in age was significantly associated with an increase length of stay (p < 0.001), postoperative complications (p = 0.004) and poorer OS(p = 0.018) but not significantly associated with major complications (p = 0.279), CSS(p = 0.338) or RFS(p = 0.941). CONCLUSION Age by itself was associated with OS after LR for HCC but was not a significant risk factor for HCC-related death.

in Singapore: Analysis of 300 cases. ANNALS OF THE ACADEMY OF MEDICINE, SINGAPORE 2021. [DOI: 10.47102/annals-acadmedsg.2021213] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 12/17/2022]
Abstract
ABSTRACT
Introduction: The introduction of laparoscopic surgery has changed abdominal surgery. We evaluated
the evolution and changing trends associated with adoption of laparoscopic liver resection (LLR) and
the experience of a surgeon without prior LLR experience.
Methods: A retrospective review of 310 patients who underwent LLR performed by a single surgeon
from 2011 to 2020 was conducted. Exclusion criteria were patients who underwent laparoscopic liver
surgeries such as excision biopsy, local ablation, drainage of abscesses and deroofing of liver cysts.
There were 300 cases and the cohort was divided into 5 groups of 60 patients.
Results: There were 288 patients who underwent a totally minimally invasive approach, including
28 robotic-assisted procedures. Open conversion occurred for 13 (4.3%) patients; the conversion rate
decreased significantly from 10% in the initial period to 3.3% subsequently. There were 83 (27.7%)
major resections and 131 (43.7%) resections were performed for tumours in the difficult
posterosuperior location. There were 152 (50.7%) patients with previous abdominal surgery, including
52 (17.3%) repeat liver resections for recurrent tumours, and 60 patients had other concomitant
operations. According to the Iwate criteria, 135 (44.7%) were graded as high/expert difficulty. Major
morbidity (>grade 3a) occurred in 12 (4.0%) patients and there was no 30-day mortality. Comparison
across the 5 patient groups demonstrated a significant trend towards older patients, higher American
Society of Anesthesiologists (ASA) score, increasing frequency of LLR with previous abdominal
surgery, increasing frequency of portal hypertension and huge tumours, decreasing blood loss and
decreasing transfusion rate across the study period. Surgeon experience (≤60 cases) and Institut
Mutualiste Montsouris (IMM) high grade resections were independent predictors of open conversion.
Open conversion was associated with worse perioperative outcomes such as increased blood loss,
transfusion rate, morbidity and length of stay.
Conclusion: LLR can be safely adopted for resections of all difficulty grades, including major resections
and for tumours located in the difficult posterosuperior segments, with a low open conversion rate.

Abstract
INTRODUCTION To investigate the changing trends in short- and long-term outcomes after partial hepatectomy(PH) for hepatocellular carcinoma(HCC) performed in the 21st century. METHODS A retrospective review was conducted on 1300 consecutive patients who underwent PH for HCC. The study cohort was divided into 3 time periods(P): P1(2000-2005), P2(2006-2011) and P3(20012-2017). RESULTS Comparison between the patients' baseline demographic features across the 3 periods demonstrated that patients were significantly older, had decreasing frequency of hepatitis B, increasing non-alcoholic fatty liver disease, lower alpha-feto protein(AFP) level, lower creatinine levels, less likely to undergo emergency surgery, less likely to undergo major hepatectomy, more likely to undergo repeat resection and minimally-invasive surgery. There was also an increase in operation time, decrease in blood loss, increase frequency in the use of Pringles manoeuvre, decrease liver failure, decrease length of stay and decrease postoperative mortality. HCC resected were of smaller size, less likely to demonstrate microvascular invasion and less likely to have close margins. This was associated with significant improvement in overall survival and recurrence free interval over time. Period of resection was an independent predictor of 90-day mortality and OS on multivariate analysis. CONCLUSION We observed a continuous improvement in postoperative outcomes including postoperative mortality and long-term survival after PH for HCC over the past 18 years.

Comparison between short and long-term outcomes after minimally invasive versus open primary liver resections for hepatocellular carcinoma: A 1:1 matched analysis. J Surg Oncol 2021; 124:560-571. [PMID: 34061361 DOI: 10.1002/jso.26556] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2020] [Revised: 03/24/2021] [Accepted: 05/16/2021] [Indexed: 12/13/2022]
Abstract
BACKGROUND This study aims to compare the short- and long-term outcomes of patients undergoing minimally invasive liver resection (MILR) versus open liver resection (OLR) for nonrecurrent hepatocellular carcinoma (HCC). METHODS Review of 204 MILR and 755 OLR without previous LR performed between 2005 and 2018. 1:1 coarsened exact matching (CEM) and 1:1 propensity-score matching (PSM) were performed. RESULTS Overall, 190 MILR were well-matched with 190 OLR by PSM and 86 MILR with 86 OLR by CEM according to patient baseline characteristics. After PSM and CEM, MILR was associated with a significantly longer operation time [230 min (interquartile range [IQR], 145-330) vs. 160 min (IQR, 125-210), p < .001] [215 min (IQR, 135-295) vs. 153.5 min (120-180), p < .001], shorter postoperative stay [4 days (IQR, 3-6) vs. 6 days (IQR, 5-8), p = .001)] [4 days (IQR, 3-5) vs. 6 days (IQR, 5-7), p = .004] and lower postoperative morbidity [40 (21%) vs. 67 (35.5%), p = .003] [16 (18.6%) vs. 27 (31.4%), p = .036] compared to OLR. MILR was also associated with a significantly longer median time to recurrence (70 vs. 40.3 months, p = .014) compared to OLR after PSM but not CEM. There was no significant difference in terms of overall survival and recurrence-free survival. CONCLUSION MILR is associated with superior short-term postoperative outcomes and with at least equivalent long-term oncological outcomes compared to OLR for HCC.

Abstract
BACKGROUND Various difficulty scoring systems (DSS) have been formulated to grade the complexity of laparoscopic hepatectomies (LH). This study aims to externally validate and compare 4 contemporary DSS including the Iwate, Institut Mutualiste Montsouris (IMM), Southampton and Hasegawa DSS in predicting the intraoperative technical difficulty and postoperative outcomes after LH. METHODS Retrospective review of 548 consecutive patients who underwent LH of which 455 met the study inclusion criteria. Outcomes measures of technical difficulty included operation time, Pringles maneuver, blood loss and blood transfusion rate. Postoperative outcomes measured included morbidity, major morbidity and postoperative hospital stay. RESULTS There was a statistically significant progressive increase in blood loss, blood transfusion rate, operation time and postoperative stay associated with all 4 DSS. There was also good calibration with respect to blood loss, operation time, Pringles maneuver, open conversion rate, postoperative morbidity, postoperative major morbidity and postoperative stay for all 4 DSS. The Southampton score demonstrated the poorest calibration in terms of operation time and discrimination in terms of application of Pringles maneuver and major morbidity amongst all 4 systems. CONCLUSION All 4 DSS significantly correlated with outcome measures associated with intraoperative technical difficulty and postoperative outcomes. The Southampton DSS was the poorest system in our cohort of patients.

Minimally invasive versus open right anterior sectionectomy and central hepatectomy for central liver malignancies: a propensity-score-matched analysis. ANZ J Surg 2021; 91:E174-E182.

Abstract
BACKGROUND The utility of minimally-invasive liver resection (MILR) for deep centrally located tumours (CLT) remains controversial. We aimed to review our institution's experience and outcomes with minimally invasive central hepatectomy (CH) and right anterior sectionectomy (RAS) for CLT in a propensity score-matched (PSM) analysis. METHODS Retrospective review of a prospectively maintained surgical database revealed 23 patients who underwent MILR (6 CH, 17 RAS) and 53 patients who underwent open liver resection (OLR; 24 CH, 29 RAS) for CLT. PSM in a 1:1 ratio identified two groups of patients with similar baseline clinicopathological characteristics. Peri-operative outcomes were then compared. RESULTS There was one laparoscopic-assisted, one robot-assisted and two laparoscopic-converted-open procedures in the MILR cohort. Across the unmatched cohort, there was only one mortality (MILR) and five patients with major morbidity (all OLR). MILR was associated with a longer operating time (P < 0.001), but shorter post-operative hospital stay (P = 0.002) and decreased morbidity (P = 0.018) in the unmatched cohort. Examination of peri-operative outcomes after PSM revealed that MILR was similarly associated with a longer operating time (P = 0.001) and shortened post-operative hospital stay (P = 0.043). OLR was associated with a significantly reduced application of Pringle manoeuvre (P = 0.004). There were no significant differences between MILR and OLR with regards to blood loss, blood transfusions, morbidity and margin status in the PSM analysis. CONCLUSION MILR for CLT is safe and feasible when performed by experienced surgeons. It is associated with shorter hospital stays but at the expense of longer operation times and more frequent application of Pringle manoeuver.

Abstract
Background: Minimally invasive liver resection (MILR) has been increasingly adopted over the past decade, and its application has been expanded to the management of extrapancreatic biliary malignancies (EPBMs). We aimed to evaluate the peri- and post-operative outcome of patients undergoing MILR for suspected EPMB. Methods: Forty-four consecutive patients who underwent MILR with a curative intent for EPBM at Singapore General Hospital between 2011 and 2018 were identified from a prospectively maintained surgical database. Clinical and operative data were analysed and compared to provide information and make comparisons on peri- and post-operative outcomes. Results: A total of 26, 5 and 13 patients underwent MILR for intrahepatic cholangiocarcinoma (ICC), perihilar cholangiocarcinoma (PHC) and gallbladder carcinoma (GBCA), respectively. Six major hepatectomies were performed, of which one was laparoscopic assisted and another was robot assisted. Ten patients underwent posterosuperior segmentectomies. There was one open conversion. The mean operative time was 266.5 min, and the mean blood loss was 379 ml. The mean length of hospital stay was 4.7 days with no incidences of 30- and 90-day mortality. The rate of recurrence-free survival (RFS) was 75% (at least 12-month follow-up). There was a significantly higher rate of robot-assisted procedures in patients undergoing MILR for GBCA/PHC as compared to ICC (P = 0.034). Patients undergoing posterosuperior segmentectomies required longer operative time (P = 0.018) with an increased need for (P = 0.001) and duration of (P = 0.025) Pringles manoeuvre. There were no differences in operative time, blood loss, morbidity, mortality or RFS between the above groups. Conclusion: Minimally invasive surgery can be adopted safely with a low open conversion rate for EPBMs.

Abstract
There has been a significant increase in the use of laparoscopic liver resection (LLR) over the past 2 decades. This study aimed to analyze the outcomes associated with LLR at a single tertiary care hospital. Patients with benign or malignant tumors who underwent LLR by a single surgeon from January 2012 to November 2019 were identified. There were 123 patients who underwent LLR in the study period; 52% were men, and the median age was 61 (24-90) years. Five patients (4.1%) had unplanned conversion to open resection. Ninety-five patients (77.2%) had a wedge resection or single segmentectomy, and 28 (22.8%) underwent resection of 2+ liver segments. Seventy-one cases (57.7%) were for hepatocellular carcinoma (HCC), 24 (19.5%) for colorectal metastasis, and 28 (22.8%) were for other benign and malignant tumors. Median operative time was 239 (range 89-526) minutes. Mean estimated blood loss was 192 (range 0-1800) mL. The median length of stay (LOS) overall was 2 (range 0-9) days. From 2017 to 2019, the mean LOS was 1.2 days, compared to a mean LOS of 3.3 days from 2012 to 2016. More cases were performed as same-day surgery from 2017 onward; 19 patients (33.9%) had same-day surgery from 2017 to 2019, in comparison to only 1 patient (1.5%) in the period of 2012-2016 (P < .0001). Overall, 28 patients (22.8%) experienced postoperative morbidity; major postoperative morbidity occurred in 4 patients (3.3%). The 90-day mortality was .8%, and the 30-day readmission rate was 5.7%. In conclusion, LLR can be performed safely to treat liver tumors, and LOS decreased over time. Although overall morbidity is moderate, serious morbidity is low, as was the readmission rate. Laparoscopic wedge resection may be a feasible option as an outpatient procedure in select patients.

Abstract
BACKGROUND Minimally invasive pancreatic surgeries (MIPS) are increasingly adopted worldwide. However, it remains uncertain if these reported experiences are reproducible throughout the world today. This study examines the safety and evolution of MIPS at a single institution in Southeast Asia. METHODS This is a retrospective review of 150 consecutive patients who underwent MIPS between 2006 and 2018 of which 135 cases (90%) were performed since 2012. To determine the evolution of MIPS, the study population was stratified into 3 equal groups of 50 patients. Comparison was also made between pancreatoduodenectomies (PD), distal pancreatectomies (DP) and other pancreatic surgeries. RESULTS One hundred and fifty patients underwent MIPS (103 laparoscopic, 45 robotic and 2 hand-assisted). Forty-three patients underwent PD, 93 DP and 14 other MIPS. There were 21 (14.0%) open conversions. There was an exponential increase in caseload over the study period. Comparison across the 3 time periods demonstrated that patients were significantly more likely to have a higher American Society of Anesthesiologists score, older, undergo PD and a longer operation time. The conversion rate decreased from 28% to 0% and increased again to 14% across the 3 time periods. Comparison between the various types of MIPS demonstrated that patients who underwent PD were significantly older, more likely to have symptomatic tumours, had longer surgery time, increased blood loss, increased frequency of extended pancreatectomies, increased frequency of hybrid procedures, longer post-operative stay, increased post-operative morbidity rate and increased post-operative major morbidity rate. CONCLUSION The case volume of MIPS increased rapidly at our institution over the study period. Furthermore, although the indications for MIPS expanded to include more complex procedures in higher risk patients, there was no change in key perioperative outcomes.

Abstract
Introduction: This study aims to evaluate the impact of first assistant surgeon experience on the outcomes of laparoscopic hepatectomies in a university-affiliated teaching hospital. Methods: This is a retrospective study comparing outcomes of laparoscopic hepatectomies with first assistant surgeons of varying experience levels. Three hundred and eighty-five consecutive laparoscopic hepatectomies performed in a tertiary university-affiliated teaching hospital from 2012 to 2018 were included and stratified into three cohorts-Group 1 in which assistants were residents, Group 2 for fellows, and Group 3 for attendings. Baseline clinicopathologic variables and outcome measures were analyzed using the augmented inverse probability of treatment weighting approach, which is a propensity score-based method that combines aspects of covariate adjustment and inverse probability weighting. Results: Group 3 comprised a greater proportion of advanced- and expert-level surgeries based on the Iwate criteria; 33.8%, 32.2%, and 46.0% of patients underwent advanced- and expert-level surgeries in Groups 1, 2, and 3, respectively. Group 3 had consistently higher operative times as well as more frequent use and longer duration of Pringle's maneuver (P < .05). The median operative times for Groups 1, 2, and 3 were 195, 195, and 290 minutes, respectively. Pringle's maneuver was applied in 26.9%, 33.9%, and 60.2% of patients with a corresponding median duration of 35, 36, and 45 minutes, respectively. None of the other perioperative and postoperative outcomes demonstrated statistically significant differences. Conclusion: With an appropriate selection of cases, participation of residents as first assistants in laparoscopic hepatectomies can be encouraged without compromise in perioperative outcomes.

Abstract
BACKGROUND This study aims to determine the safety and efficacy of laparoscopic repeat liver resection (LRLR) for recurrent hepatocellular carcinoma (rHCC). METHODS Twenty patients underwent LRLR for rHCC between 2015 and 2017. The control groups consisted of 79 open RLR (ORLR) for rHCC and 185 LLR for primary HCC. We undertook propensity score-adjusted analyses (PSA) and 1:1 propensity score matching (PSM) for the comparison of LRLR versus ORLR. Comparison of LRLR versus LLR was done using multivariable regression models with adjustment for clinically relevant covariates. RESULTS Twenty patients underwent LRLR with three open conversions (15%). Both PSA and 1:1-PSM demonstrated that LRLR was significantly associated with a shorter stay, superior disease-free survival (DFS) but longer operation time compared to ORLR. Comparison between LRLR versus LLR demonstrated that patients undergoing LRLR were significantly older, had smaller tumors, longer operation time and decreased frequency of Pringle's maneuver applied. There was no difference in other key perioperative outcomes. CONCLUSION The results of this study demonstrate that in highly selected patients; LRLR for rHCC is feasible and safe. LRLR was associated with a shorter hospitalization but longer operation time compared to ORLR. Moreover, other than a longer operation time, LRLR was associated with similar perioperative outcomes compared to LLR for primary HCC.

Abstract
Introduction There are limited data to date regarding laparoscopic liver resection (LLR) for spontaneously ruptured hepatocellular carcinoma (srHCC). We performed this study to determine the safety and feasibility of LLR for srHCC. Materials and Methods We conducted a retrospective review of all patients who underwent liver resection for srHCC from 2000 to 2018. A total of five patients underwent LLR for srHCC, and they were matched to 10 patients who underwent open liver resection (OLR) for srHCC to perform a 1:2 comparison. A separate cohort of patients who underwent LLR for non-ruptured HCC (nrHCC) was also compared against the laparoscopic group. Results The comparison between LLR versus OLR for srHCC demonstrated no significant differences in baseline characteristics between both groups. There was also no significant difference in perioperative outcomes such as median operating time, estimated blood loss (EBL), rate of blood transfusion, post-operative median length of stay (LOS), overall complication rates, major morbidity rates and 90-day mortality rates. Comparison between LLR for srHCC and LLR for nrHCC demonstrated no significant differences in baseline characteristics between both groups. There was also no significant difference in key perioperative outcomes such as median operating time, EBL, rate and volume of blood transfusion, median post-operative LOS, morbidity rates or mortality rates. Conclusion LLR may be performed safely in selected cases of srHCC. These patients have comparable perioperative outcomes as those who undergo OLR for srHCC and LLR for nrHCC.

Abstract
INTRODUCTION This study aims to evaluate the safety and feasibility of laparoscopic minor hepatectomy (LMH) in elderly patients with hepatocellular carcinoma (HCC). METHODS A total of 40 consecutive elderly (≥ 70 years) patients were compared with 94 young patients (< 70 years). The 40 patients were also compared with 85 consecutive elderly patients who underwent open minor hepatectomies (OMH). After 1:1 propensity-score matching (PSM), 32 LMHs were compared with 32 OMHs in elderly patients. RESULTS Comparison between the baseline characteristics of elderly and young HCC patients showed that elderly patients were significantly more likely to have comorbidities, ASA score > 2, non-hepatitis B, previous liver resection and larger tumor size. Comparison between perioperative outcomes demonstrated that elderly patients were significantly more likely to have a longer operation time, increased blood loss, increased need for blood transfusion, longer Pringles duration and longer postoperative stay. Comparison between LMH and OMH in elderly patients demonstrated no significant difference in baseline characteristics except the LMH cohort were significantly more likely to have > 1 comorbidity, higher platelet count and lower median AFP level. Comparison between outcomes before and after PSM demonstrated that LMH was associated with longer operation time, increased blood loss, longer Pringles duration but decreased postoperative pulmonary complications and shorter postoperative stay compared to OMH. CONCLUSION LMH is safe and feasible in elderly patients with HCC. However, LMH in elderly patients is associated with poorer perioperative outcomes compared to LMH in young patients. Comparison between LMH and OMH in elderly patients demonstrated advantages in terms of decreased pulmonary complications and shorter length of stay at the expense of increased operation time and blood loss.

Abstract
BACKGROUND Several studies published mainly from pioneers and early adopters have documented the evolution of minimally invasive hepatectomy (MIH). However, questions remain if these reported experiences are applicable and reproducible today. This study examines the changing trends, safety, and outcomes associated with the adoption of MIH based on a contemporary single-institution experience. METHODS This is a retrospective review of 400 consecutive patients who underwent MIH between 2006 and 2017 of which 360 cases (90%) were performed since 2012. To determine the evolution of MIH, the study population was stratified into four equal groups of 100 patients. Analyses were also performed of predictive factors and outcomes of open conversion. RESULTS Four hundred patients underwent MIH of which 379 (94.8%) were totally laparoscopic/robotic. Eighty-eight (22.0%) patients underwent major hepatectomy and 160 (40.0%) had resection of tumors located in the posterosuperior segments. There were 38 (9.5%) open conversions. Comparison across the four groups demonstrated that patients were older, had higher ASA score, and had increased frequency of previous abdominal surgery and repeat liver resections. There was also an increase in the proportion of patients who underwent totally laparoscopic/robotic surgery, major liver resection, resection of ≥ 3 segments, and multiple resections. Comparison of outcomes demonstrated that there was a significant decrease in open conversion rate, longer operation time, and increased use of Pringles maneuver. The presence of cirrhosis and institution experience (1st 100 cases) were independent predictors of open conversion. Patients who required open conversion had significantly increased operation time, blood loss, blood transfusion rate, morbidity, and mortality. CONCLUSION The case volume of MIH performed increased rapidly at our institution over time. Although the indications of MIH expanded to include higher risk patients and more complex hepatectomies, there was a decrease in open conversion rate and no change in other perioperative outcomes.

Abstract
Introduction: Minimally invasive surgery (MIS) for gallbladder cancer (GBCa) has traditionally been discouraged, with limited studies reporting on its outcomes. The aim of this study was to evaluate the short-term outcomes of MIS for patients with GBCa or suspected GBCa. Methods: A retrospective study of 8 consecutive patients who underwent MIS for GBCa by a single surgeon over a 22-month period between 2015 and 2017. Results: Three patients underwent robotic surgery, while five underwent conventional laparoscopic surgery. Four patients presented with histologically proven GbCa detected incidentally after cholecystectomy. All 4 patients underwent resection of Segment 4b/5. Of these, 3 underwent hilar lymphadenectomy and 1 underwent hilar lymph node sampling. Four patients presenting with suspected GBCa underwent upfront extended cholecystectomy. Two patients who had malignancy on frozen section underwent hilar lymphadenectomy. The median operation time was 242.5 (range, 165–530) min, and the median blood loss was 175 (range, 50–700) ml. The median post-operative hospital stay was 3.5 (range, 2–8) days. There were no open conversion, post-operative morbidities and mortalities. Six had histologically proven GBCa. Five were T3 and one had T2 cancers. Conclusions: The results of the present study confirm the short-term safety and feasibility of MIS for patients with GBCa, as all eight patients underwent successful MIS with no major morbidity or mortality. Further studies with larger patient cohorts with long-term follow-up are needed to determine the oncologic outcomes and the definitive role of MIS in treating GBCa.

Abstract
BACKGROUND Most studies analyzing the learning experience of laparoscopic liver resection (LLR) focused on the experience of one or two expert pioneering surgeons. This study aims to critically analyze the impact of individual surgeon experience on the outcomes of LLR based on the contemporary collective experiences of multiple surgeons at single institution. METHODS Retrospective review of 324 consecutive LLR from 2006 to 2016. The cases were performed by 10 surgeons over various time periods. Four surgeons had individual experience with <20 cases, four surgeons with 20-30 cases, and two surgeons with >90 cases. The cohort was divided into two groups: comparing a surgeon's experience between the first 20, 30, 40, and 50 cases with patients treated thereafter. Similarly, we performed subset analyses for anterolateral lesions, posterosuperior lesions, and major hepatectomies. RESULTS As individual surgeons gained increasing experience, this was significantly associated with older patients being operated, decreased hand-assistance, larger tumor size, increased liver resections, increased major resections, and increased resections of tumors located at the posterosuperior segments. This resulted in significantly longer operation time and increased use of Pringle maneuver but no difference in other outcomes. Analysis of LLR for tumors in the posterosuperior segments demonstrated that there was a significant decrease in conversion rates after a surgeon had experience with 20 LLR. For major hepatectomies, there was a significant decrease in morbidity, mortality, and length of stay after acquiring experience with 20 LLR. CONCLUSION LLR can be safely adopted today especially for lesions in the anterolateral segments. LLR for lesions in the difficult posterosuperior segments and major hepatectomies especially in cirrhosis should only be attempted by surgeons who have acquired a minimum experience with 20 LLR.

Abstract
PURPOSE Complete resection of diseased lesions reduces the recurrence of cancer, making it critical for surgical treatment. However, precisely resecting residual tumors is a challenge during operation. A novel integrated spectral-domain optical-coherence-tomography (SD-OCT) and laser-ablation therapy system for soft-biological-tissue resection is proposed. This is a prototype optical integrated diagnosis and therapeutic system as well as an optical theranostics system. METHODS We develop an optical theranostics system, which integrates SD-OCT, a laser-ablation unit, and an automatic scanning platform. The SD-OCT image of biological tissue provides an intuitive and clear view for intraoperative diagnosis and monitoring in real time. The effect of laser ablation is analyzed using a quantitative mathematical model. The automatic endoscopic scanning platform combines an endoscopic probe and an SD-OCT sample arm to provide optical theranostic scanning motion. An optical fiber and a charge-coupled device camera are integrated into the endoscopic probe, allowing detection and coupling of the OCT-aiming beam and laser spots. RESULTS The integrated diagnostic and therapeutic system combines SD-OCT imaging and laser-ablation modules with an automatic scanning platform. OCT imaging, laser-ablation treatment, and the integration and control of diagnostic and therapeutic procedures were evaluated by performing phantom experiments. Furthermore, SD-OCT-guided laser ablation provided precision laser ablation and resection for the malignant lesions in soft-biological-tissue-lesion surgery. The results demonstrated that the appropriate laser-radiation power and duration time were 10 W and 10 s, respectively. In the laser-ablation evaluation experiment, the error reached approximately 0.1 mm. Another validation experiment was performed to obtain OCT images of the pre- and post-ablated craters of ex vivo porcine brainstem. CONCLUSION We propose an optical integrated diagnosis and therapeutic system. The primary experimental results show the high efficiency and feasibility of our theranostics system, which is promising for realizing accurate resection of tumors in vivo and in situ in the future.
