The efficacy and safety of pure laparoscopic liver resection for hepatocellular carcinoma in super-elderly patients over 80 years: A multicenter propensity analysis. JOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES 2024; 31:234-242. [PMID: 38009434 DOI: 10.1002/jhbp.1395] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Revised: 10/09/2023] [Accepted: 10/11/2023] [Indexed: 11/28/2023]
Abstract
BACKGROUND Very few reports have evaluated the safety of laparoscopic liver resection in super-elderly patients. We assessed the short-term outcomes of laparoscopic liver resection in patients with hepatocellular carcinoma aged ≥80 years, using propensity score matching. METHODS We retrospectively analyzed the data of 287 patients (aged ≥80 years) who underwent liver resection for hepatocellular carcinoma at eight hospitals belonging to Hiroshima Surgical study group of Clinical Oncology, between January 2012 and December 2021. The perioperative outcomes were compared between laparoscopic and open liver resection, using propensity score matching. RESULTS Of the 287 patients, 83 and 204 were included in the laparoscopic and open liver resection groups, respectively. Propensity score matching was performed, and 52 patients were included in each group. The operation (p = .68) and pringle maneuver (p = .11) time were not different between the groups. There were no significant differences in the incidences of bile leakage or organ failure. The laparoscopic liver resection group had significantly less intraoperative bleeding and a lower incidence of cardiopulmonary complications (both p < .01). CONCLUSIONS Laparoscopic liver resection can be safely performed in elderly patients aged ≥80 years.

Abstract
Purpose Laparoscopic left lateral sectionectomy (L-LLS) stands as a cornerstone procedure in hepatobiliary minimal surgery, frequently employed for various benign and malignant liver lesions. This study aimed to analyze the peri- and postoperative surgical outcomes of single-port robotic left lateral sectionectomy (SPR-LLS) vs. those of L-LLS in patients with hepatic tumors. Methods From January 2020 through June 2023, 12 patients underwent SPR-LLS. During the same period, 30 L-LLS procedures were performed. In total, 12 patients in the robotic group and 24 patients in the laparoscopic group were matched. Results When the SPR-LLS and L-LLS groups were compared, the operation time was longer in the SPR-LLS group with less blood loss and shorter hospital stay. Postoperative complications were observed in 3 patients in the L-LLS group (12.5%) and 1 patient in the SPR-LLS group (8.3%). Conclusion SPR-LLS using the da Vinci SP system was comparable to laparoscopic LLS in terms of surgical outcomes. SPR-LLS was associated with lower blood loss and less postoperative length of stay compared to L-LLS. These findings suggest that left lateral sectionectomy is technically feasible and safe with the da Vinci SP system in select patients.

Abstract
BACKGROUND This study was designed to investigate the feasibility and safety of laparoscopic hepatic caudate lobectomy (LHCL) for treating liver tumor by comparing with the open hepatic caudate lobectomy (OHCL). METHODS In the LHCL group, we included 24 patients with liver tumor received LHCL in Qilu Hospital of the Shandong University from January 2014 to January 2019. Meanwhile, 24 matched liver tumor patients underwent OHCL in our hospital served as control. Then we compared the patient characteristics, intraoperative parameters, and postoperative outcomes between LHCL group and OHCL group. RESULTS There were no significant differences in gender, age, degree of cirrhosis, tumor size, preoperative liver function, Child-Pugh grading, proportion of liver cirrhosis, and tumor size between LHCL group and OHCL group (P > 0.05). No death was reported in both groups. The length of incision in LHCL group was significantly lower than that in OHCL group (4.22 ± 1.14 cm vs. 22.46 ± 4.40 cm, P < 0.001). The intraoperative blood loss in LHCL group was significantly lower than that of OHCL group (116.82 ± 71.61 ml vs. 371.74 ± 579.35 ml, P = 0.047). The total operation time, Pringle maneuver occlusion time, and blocking rate in LHCL group showed no statistical difference compared with those of the OHCL group (P > 0.05). The VAS scores at postoperative 24 and 48 h showed no statistical differences between LHCL group and OHCL group (P > 0.05). Compared with the OHCL group, significant decrease was noticed in the proportion of patients with severe pain 48 h after surgery (0 vs. 4.25 ± 0.46, P < 0.001) and dezocine consumption (90.45 ± 45.77 mg vs. 131.6 ± 81.30 mg, P = 0.0448) in the LHCL group. CONCLUSION LHCL is effective and feasible for treating liver tumor, which is featured by reducing intraoperative blood loss and serious pain.

Abstract
INTRODUCTION Since its first appearance in the early 1990s, laparoscopic hepatic resection has become increasingly accepted and recognized as safe as laparotomy. The recent introduction of robotic surgery systems has brought new innovations to the field of minimally invasive surgery, such as laparoscopic surgery. The da Vinci line of surgical systems has recently released a true single-port platform called the da Vinci SP system, which has 3 fully wristed and elbowed instruments and a flexible camera in a single 2.5 cm cannula. We present the first case of robotic liver resection using the da Vinci SP system and demonstrate the technical feasibility of this platform. PATIENT CONCERNS AND DIAGNOSIS A 63-year-old woman presented with elevated liver function test results and abdominal pain. Computed tomography (CT) and magnetic resonance cholangiopancreatography showed multiple intrahepatic duct stones in the left lateral section and distal common bile duct stones near the ampulla of Vater. INTERVENTIONS The docking time was 8 minute. The patient underwent successful da Vinci SP with a total operation time of 135 minute. The estimated blood loss was 50.0 ml. No significant intraoperative events were observed. OUTCOMES The numerical pain intensity score was 3/10 in the immediate postoperative period and 1/10 on postoperative day 2. The patient was discharged on postoperative day 5 after verifying that the CT scan did not show any surgical complications. CONCLUSION We report a technique of left lateral sectionectomy, without the use of an additional port, via the da Vinci SP system. The present case suggests that minor hepatic resection is technically feasible and safe with the new da Vinci SP system in select patients. For the active application of the da Vinci SP system in hepatobiliary surgery, further device development and research are needed.

Abstract
Background Despite the development of laparoscopic surgery, there are still inherent limitations associated with conventional laparoscopic instruments such as restrictions in movement and an inability for articulation. Robotic surgery may help to overcome the limitations of conventional laparoscopic surgery. The aim of this study was to present our initial experience with robotic hepatectomy (RH) and discuss the steps required to develop an RH program at a high-volume laparoscopic hepatectomy (LH) center. Methods We retrospectively reviewed prospectively collected data for 14 consecutive patients who underwent RH between 2017 and 2018. Clinicopathological characteristics and perioperative outcomes were compared with those reported in previous studies. The operation time of each procedure was analyzed to assess RH proficiency based on experience. Results Of the 14 patients, 12 patients (85.7%) underwent robotic major hepatectomy. Median patient age was 54.5 years, while median body mass index (BMI) was 25.2 kg/m2. The median operation time was 360 (range: 145–544) min. The median estimated blood loss (EBL) was 300 (range: 50–1,400) mL. Conversion to open surgery was not required in any case. The median length of hospital stay was 5 (range: 4–14) days. Major complications occurred in 2 patients (14.2%), although both recovered without sequelae. The time required for hilar dissection, docking, and parenchymal transection gradually decreased after the first two cases of RH. Conclusions From our initial experience, RH might be considered as a feasible procedure in the liver resection, even in major hepatectomy. In addition, surgeons with sufficient experience in LH could rapidly adapt for RH. However, we have to make a system for education and monitoring of this innovative surgery for the patients’ safety.

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.

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
Background: Minimally-invasive pancreato-biliary surgery (MIPBS) is increasingly reported worldwide. This study examines the changing trends, safety and outcomes associated with the adoption of MIPBS based on a contemporary experience of an early adopter in Southeast Asia. Methods: Retrospective review of 114 consecutive patients who underwent MIPBS by a single surgeon over 86 months from 2011. The study population was stratified into three equal groups of 38 patients. Comparison was also performed between minimally-invasive pancreato surgery (MIPS) and minimally-invasive biliary surgery (MIBS). Results: There were 70 MIPS and 44 MIBS. Sixty-three cases (55.3%) were performed using robotic assistance and fourteen (12.3%) were hybrid procedures with open reconstruction. Forty-four (38.6%) procedures were performed for malignancy. There were 8 (7.0%) open conversions and median operation time was 335 (range, 60–930) min. There were nine extended pancreatectomies including seven involving vascular reconstructions. Major morbidity (>Grade 2) occurred in 20 (17.5%) patients including 6 (5.3%) reoperations and there was no mortality. Comparison across the three groups demonstrated that with increasing experience, there was a significant trend in a higher proportion of higher ASA score patients, increasing frequency of procedures requiring anastomosis and increasing the use of robotic assistance without significant difference in key perioperative outcomes such as open conversion rate, morbidity and hospital stay. Comparison between MIPS and MIBS demonstrated that MIPS was associated with significantly longer operation time, increased blood loss, increased transfusion rate, longer hospital stay, increased readmission rate and increased morbidity. Conclusion: MIPBS can be safely adopted today with a low open conversion rate.

Changing trends and outcomes associated with the adoption of minimally invasive hepatectomy: a contemporary single-institution experience with 400 consecutive resections. Surg Endosc 2018; 32:4658-4665. [PMID: 29967997 DOI: 10.1007/s00464-018-6310-1] [Citation(s) in RCA: 67] [Impact Index Per Article: 11.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2018] [Accepted: 06/18/2018] [Indexed: 12/15/2022]
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.

Critical appraisal of the impact of individual surgeon experience on the outcomes of laparoscopic liver resection in the modern era: collective experience of multiple surgeons at a single institution with 324 consecutive cases. Surg Endosc 2017; 32:1802-1811. [PMID: 28916894 DOI: 10.1007/s00464-017-5864-7] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2017] [Accepted: 08/22/2017] [Indexed: 12/16/2022]
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.
