Abstract
Pure laparoscopic donor hepatectomy (PLDH) has become a standard practice for living donor liver transplantation in expert centers. Accurate understanding of biliary structures is crucial during PLDH to minimize the risk of complications. This study aims to develop a deep learning-based segmentation model for real-time identification of biliary structures, assisting surgeons in determining the optimal transection site during PLDH. A single-institution retrospective feasibility analysis was conducted on 30 intraoperative videos of PLDH. All videos were selected for their use of the indocyanine green near-infrared fluorescence technique to identify biliary structure. From the analysis, 10 representative frames were extracted from each video specifically during the bile duct division phase, resulting in 300 frames. These frames underwent pixel-wise annotation to identify biliary structures and the transection site. A segmentation task was then performed using a DeepLabV3+ algorithm, equipped with a ResNet50 encoder, focusing on the bile duct (BD) and anterior wall (AW) for transection. The model's performance was evaluated using the dice similarity coefficient (DSC). The model predicted biliary structures with a mean DSC of 0.728 ± 0.01 for BD and 0.429 ± 0.06 for AW. Inference was performed at a speed of 15.3 frames per second, demonstrating the feasibility of real-time recognition of anatomical structures during surgery. The deep learning-based semantic segmentation model exhibited promising performance in identifying biliary structures during PLDH. Future studies should focus on validating the clinical utility and generalizability of the model and comparing its efficacy with current gold standard practices to better evaluate its potential clinical applications.

Ann Hepatobiliary Pancreat Surg 2024; 28:337-343. [PMID: 38566519 PMCID: PMC11341885 DOI: 10.14701/ahbps.24-020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Revised: 03/11/2024] [Accepted: 03/12/2024] [Indexed: 04/04/2024] Open
Abstract
Backgrounds/Aims Challenges arise when translating pure laparoscopic donor right hepatectomy (PLDRH) results from Asian to Western donors, due to differences in body mass index (BMI). This study compares the outcomes of PLDRH and conventional open donor right hepatectomy (CDRH) in donors with BMI over 30. Methods Medical records of live liver donors (BMI > 30) undergoing right hepatectomy (2010-2021) were compared: 25 PLDRH cases vs. 19 CDRH cases. Donor and recipient demographics, operative details, and outcomes were analyzed. Results PLDRH and CDRH had similar donor and recipient characteristics. PLDRH had longer liver removal and warm ischemic times, but a shorter post-liver removal duration than CDRH. Donor complication rates were comparable, with the highest complication being grade IIIa in PLDRH, necessitating needle aspiration for biloma on postoperative day 11. Fortunately, this donor fully recovered without additional treatment. No complications exceeding Clavien-Dindo grade IIIa occurred in either group. Recipient outcomes between the groups were similar. Conclusions This study supports PLDRH as a viable option for donors with BMI over 30, challenging the notion that high BMI should deter considering PLDRH. The findings provide valuable insights into the safety and feasibility of PLDRH, encouraging further exploration of this technique in diverse donor populations.

Int J Surg 2024; 110:3203-3211. [PMID: 38477118 PMCID: PMC11175737 DOI: 10.1097/js9.0000000000001317] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Accepted: 02/26/2024] [Indexed: 03/14/2024]
Abstract
BACKGROUND Although the adoption of pure laparoscopic donor hepatectomy has expanded driven by considerations of donor cosmesis and function, the criteria for selecting candidates for pure laparoscopic donor right hepatectomy (PLDRH) continue to be debated. This study aimed to delineate the distinctive characteristics of donors and recipients who underwent conventional open-donor right hepatectomy (CDRH) during the era of PLDRH. MATERIALS AND METHODS The authors conducted a retrospective review of a prospectively collected single-centre database encompassing all right hepatectomies at Seoul National University Hospital from April 2016 to December 2021, a period during which there were no absolute contraindications for PLDRH. RESULTS During the exclusive PLDRH period, there were still 63 cases of CDRH alongside 362 cases of PLDRH. The CDRH donors were older, had a lower estimated remnant liver volume, and a higher incidence of expected multiple openings in the portal vein and bile duct based on preoperative imaging compared with PLDRH donors. In the subgroup analysis, including only donors meeting two or more criteria (age ≥40 years, estimated remnant liver volume ≥35%, or multiple anticipated vessel openings), recipients in the PLDRH group exhibited significantly more early major complications ( P =0.029) compared with those in the CDRH group. CONCLUSION As PLDRH gains traction in practice, it is essential to acknowledge that specific donor conditions, such as advanced age, limited remnant liver volume, and anticipation of multiple portal or bile duct openings, may merit contemplating CDRH as a means of optimizing recipient outcomes.

Abstract
В педиатрической практике трансплантация фрагментов печени позволяет достичь высоких результатов [Bowring M.G., 2020] и, при этом, полностью гарантировать безопасность родственных доноров. В то же время, при выполнении трансплантации «взрослый – ребенок», практически отсутствуют этические вопросы, поскольку, чаще всего, донором является один из родителей реципиента. Тем не менее, важной задачей остается создание условий для ускорения реабилитации и минимизации хирургической травмы у донора, в этой связи, внедрение миниинвазивных методов имеет особое значение.
В последние два десятилетия миниинвазивные подходы к резекциям печени прочно вошли в арсенал крупных гепатобилиарных центров. Это стало возможным благодаря накопленному опыту открытой хирургии печени, а также технологическому прогрессу [Morise Z., 2017]. Однако, применение лапароскопического подхода у родственных доноров фрагментов печени по-прежнему остается предметом живого интереса в трансплантологических центрах всего мира. Первые сравнительные исследования оказались весьма обнадеживающими и продемонстрировали перспективность этого подхода [Broering D. C., 2018]. Накопление подобного опыта, анализ кривой обучения, стандартизация хирургической техники по-прежнему являются важными вопросами развития данного направления.
В России лапароскопическое изъятие фрагмента печени для последующей трансплантации было впервые выполнено в ФГБУ «НМИЦ ТИО им. Академика В. И. Шумакова» в 2016 году. Также, в России впервые в мире произведено полностью лапароскопическое изъятие одновременно фрагмента печени и почки для последующей трансплантации детям [Готье С. В., 2016, Gautier S. V., 2019].
Цель исследования.
Оптимизация хирургической техники и результатов лапароскопического изъятия левого латерального сектора у прижизненных доноров фрагмента печени на основании анализа накопленного опыта.
Задачи исследования.
1. Сравнить результаты открытого и лапароскопического изъятия левого латерального сектора у прижизненных доноров.
2. Определить критерии селекции прижизненных доноров для лапароскопического изъятия левого латерального сектора печени.
3. Стандартизировать хирургическую технику выполнения лапароскопической латеральной секторэктомии печени.
4. Оценить результаты трансплантации левого латерального сектора, полученного открытым и лапароскопическим путём, у реципиентов.
5. Изучить кривую обучения выполнения лапароскопической латеральной секторэктомии печени у родственного донора.
Научная новизна.
На сегодняшний день, лапароскопическое изъятие левого латерального сектора печени у прижизненных доноров выполняется лишь в нескольких центрах в мире. Суммарный накопленный опыт по всему миру не превышает 500 операций. В настоящее время, по данным литературы, существует лишь несколько исследований, посвященных данной тематике. Проведение псевдорандомизации позволило объективизировать результаты и увеличить их достоверность. Изучение кривой обучения выполнения лапароскопической латеральной секторэктомии печени позволяет оценить потенциал внедрения данной методики в клинические центры.
Новыми являются данные сравнительного анализа клинических результатов проведения открытого и лапароскопического изъятия левого латерального сектора печени у живых доноров, а также сравнительного анализа результатов трансплантаций у реципиентов, получивших соответствующие трансплантаты.
Новыми являются разработанные рекомендации по селекции доноров для лапароскопического изъятия левого латерального сектора.
Впервые разработаны алгоритмы, протоколы и рекомендации по выполнению хирургического вмешательства лапароскопической резекции левого латерального сектора печени у родственного донора.
Практическая значимость исследования.
Впервые в России на основании доказательной медицины установлена клиническая эффективность и безопасность лапароскопической левой латеральной секторэктомии у прижизненных доноров фрагмента печени.
Разработана и стандартизирована хирургическая техника, позволяющая максимально снизить интра- и послеоперационные осложнения у доноров левого латерального сектора печени, а также получать трансплантаты высокого качества.
Внедрение научных разработок в клиническую практику позволит:
• обезопасить хиругическое пособие у доноров путем снижения интраоперационой кровопотери и минимизации хирургической травмы;
• ускорить послеоперационную реабилитацию у доноров;
• получить хороший косметический эффект после оперативного пособия.
Методология и методы исследования.
В исследовании проведен статистический анализ клинических данных, результатов оперативного вмешательства, лабораторных и инструментальных исследований до, во время и после резекции левого латерального сектора печени у родственных доноров и трансплантации левого латерального сектора
детям. Проведен статистический анализ клинических данных, результатов трансплантаций левого латерального сектора печени у реципиентов, получивших трансплантат от доноров, оперированных открыто и лапароскопически.
Основные положения, выносимые на защиту
1. Лапароскопическое изъятие левого латерального сектора является эффективным и безопасным методом, позволяющим уменьшить операционную травму и ускорить реабилитацию, а также получить хороший косметический эффект.
2. Результаты трансплантации левого латерального сектора печени детям от доноров, оперированных лапароскопически, сопоставимы с аналогичными от доноров, оперированных по классической открытой методике.
3. Унификация хирургической методики позволяет уменьшить длительность операции, а также позволяет добиться максимального снижения интра- и послеоперационных осложнений у доноров.
4. Более строгая селекция доноров для лапароскопического изъятия левого латерального сектора позволяет снизить риск интраоперационных осложнений на этапе становления методики и наработки хирургического опыта.

Systematic review and meta-analysis of open versus laparoscopy-assisted versus pure laparoscopic versus robotic living donor hepatectomy. Liver Transpl 2023; 29:1063-1078.

Abstract
The value of minimally invasive approaches for living donor hepatectomy remains unclear. Our aim was to compare the donor outcomes after open versus laparoscopy-assisted versus pure laparoscopic versus robotic living donor hepatectomy (OLDH vs. LALDH vs. PLLDH vs. RLDH). A systematic literature review of the MEDLINE, Cochrane Library, Embase, and Scopus databases was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement (up to December 8, 2021). Random-effects meta-analyses were performed separately for minor and major living donor hepatectomy. The risk of bias in nonrandomized studies was assessed using the Newcastle-Ottawa Scale. A total of 31 studies were included. There was no difference in donor outcomes after OLDH versus LALDH for major hepatectomy. However, PLLDH was associated with decreased estimated blood loss, length of stay (LOS), and overall complications versus OLDH for minor and major hepatectomy, but also with increased operative time for major hepatectomy. PLLDH was associated with decreased LOS versus LALDH for major hepatectomy. RLDH was associated with decreased LOS but with increased operative time versus OLDH for major hepatectomy. The scarcity of studies comparing RLDH versus LALDH/PLLDH did not allow us to meta-analyze donor outcomes for that comparison. There seems to be a marginal benefit in estimated blood loss and/or LOS in favor of PLLDH and RLDH. The complexity of these procedures limits them to transplant centers with high volume and experience. Future studies should investigate self-reported donor experience and the associated economic costs of these approaches.

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
OBJECTIVE This study analyzed the incidence and risk factors for surgical morbidities of laparoscopic living donors. BACKGROUND Although laparoscopic living donor programs have been established safely in leading centers, donor morbidities have not been discussed sufficiently. METHODS Laparoscopic living donors operated on from May 2013 to June 2022 were reviewed. Donor complications were reviewed, and factors related to bile leakage and biliary stricture were analyzed using the multivariable logistic regression method. RESULTS A total of 636 donors underwent laparoscopic living donor hepatectomy. The open conversion rate was 1.6%, and the 30-day complication rate was 16.8% (n=107). Grade IIIa and IIIb complications occurred in 4.4% (n=28) and 1.9% (n=12) of patients, respectively. The most common complication was bleeding (n=38, 6.0%). Fourteen donors (2.2%) required reoperation. Portal vein stricture, bile leakage, and biliary stricture occurred in 0.6% (n=4), 3.3% (n=21), and 1.6% (n=10) of cases, respectively. The readmission rate and reoperation rate were 5.2% (n=33) and 2.2% (n=14), respectively. Risk factors related to bile leakage were 2 hepatic arteries in the liver graft (OR=13.836, CI=4.092-46.789, P <0.001), division-free margin<5 mm from the main duct (OR=2.624, CI=1.030-6.686, P =0.043), and estimated blood loss during operation (OR=1.002, CI=1.001-1.003, P =0.008), while the Pringle maneuver (OR=0.300, CI=0.110-0.817, P =0.018) was protective against leakage. Regarding biliary stricture, bile leakage was the only significant factor (OR=11.902, CI=2.773-51.083, P =0.001). CONCLUSIONS Laparoscopic living donor surgery showed excellent safety for the majority of donors, and critical complications were resolved with proper management. To minimize bile leakage, cautious surgical manipulation is needed for donors with complex hilar anatomy.

Kim NR, Han DH, Choi GH, Lee JG, Joo DJ, Kim MS, Choi JS. Comparison of surgical outcomes and learning curve for robotic versus laparoscopic living donor hepatectomy: A retrospective cohort study. Int J Surg 2022; 108:107000. [PMID: 36379423 DOI: 10.1016/j.ijsu.2022.107000] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2022] [Revised: 10/20/2022] [Accepted: 11/03/2022] [Indexed: 11/15/2022]
Abstract
BACKGROUND Both laparoscopic living donor right hemihepatectomy (LLDRH) and robotic living donor right hemihepatectomy (RLDRH) have been developed for minimally invasive donor hepatectomy (MIDH), although comparative analysis between the two surgical modalities is lacking. This study aims to compare surgical outcomes of LLDRH and RLDRH at a single institution. MATERIALS AND METHODS From March 2016 to March 2022, 171 patients who underwent MILH of right liver were enrolled and divided into RLDRH and LLDRH. Two surgeons with experience in both techniques performed all procedures. Clinical characteristics, perioperative outcomes of donor and recipient, and donor anatomic variations were compared between both groups, and learning curves were estimated. Subgroup analysis was also performed, including only donors recruited after 2019, when LLDRH was initiated at our institution. RESULTS RLDRH and LLDRH were performed for 102 and 69 patients, respectively. Operative time was significantly longer for RLDRH than LLDRH (464 vs. 407 min, P < 0.001), although estimated blood loss was lower in RLDRH (104 vs. 238 mL, P = 0.002). Incidence of major complications was similar in both groups. After 2019, significantly more RLDRH vs. LLDRH patients had variation in the hepatic artery (14.3% vs. 2.9%, P = 0.020) and portal vein (16.1% vs. 4.3%, P = 0.027). Learning curve for RLDRH was stabilized after approximately the 16th case, whereas that of LLDRH stabilized immediately. CONCLUSION RLDRH resulted in less intraoperative bleeding and comparable postoperative outcomes than LLDRH. Moreover, since 2019, RLDRH has been employed more frequently for donors with hilar structure anatomic variations. Based on our single-center experience, we propose that standardized procedures for RLDRH might help set up pure minimally invasive procedures for donor hepatectomy and facilitate safe implementation of laparoscopic approaches.

Abstract
The introduction of robotics in living donor liver transplantation has been revolutionary. We aimed to examine the safety of robotic living donor right hepatectomy (RLDRH) compared to open (ODRH) and laparoscopic (LADRH) approaches. A systematic review was carried out in Medline and six additional databases following PRISMA guidelines. Data on morbidity, postoperative liver function, and pain in donors and recipients were extracted from studies comparing RLDRH, ODRH, and LADRH published up to September 2020; PROSPERO (CRD42020214313). Dichotomous variables were pooled as risk ratios and continuous variables as weighted mean differences. Four studies with a total of 517 patients were included. In living donors, the postoperative total bilirubin level (MD: −0.7 95%CI −1.0, −0.4), length of hospital stay (MD: −0.8 95%CI −1.4, −0.3), Clavien−Dindo complications I−II (RR: 0.5 95%CI 0.2, 0.9), and pain score at day > 3 (MD: −0.6 95%CI −1.6, 0.4) were lower following RLDRH compared to ODRH. Furthermore, the pain score at day > 3 (MD: −0.4 95%CI −0.8, −0.09) was lower after RLDRH when compared to LADRH. In recipients, the postoperative AST level was lower (MD: −0.5 95%CI −0.9, −0.1) following RLDRH compared to ODRH. Moreover, the length of stay (MD: −6.4 95%CI −11.3, −1.5) was lower after RLDRH when compared to LADRH. In summary, we identified low- to unclear-quality evidence that RLDRH seems to be safe and feasible for adult living donor liver transplantation compared to the conventional approaches. No postoperative deaths were reported.

Comparative outcomes of pure laparoscopic and open donor right hepatectomy: the first report from a Southeast Asian transplant center. BMC Surg 2022; 22:48. [PMID: 35148721 PMCID: PMC8832827 DOI: 10.1186/s12893-022-01507-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2021] [Accepted: 02/01/2022] [Indexed: 11/29/2022] Open
Abstract
Background Pure laparoscopic donor right hepatectomy (PLDRH) can provide better operative outcomes for the donor than conventional open donor right hepatectomy (CODRH). However, the complexity of the procedure typically makes transplant teams reluctant to perform it, especially in low-volume transplant centers. We compared the outcomes of PLDRH and CODRH to demonstrate the feasibility of PLDRH in a low-volume transplant program. Methods We carried out a retrospective study of adult living donor liver transplantation in Chiang Mai University Hospital from January 2015 to March 2021. The patients were divided into a PLDRH group and a CODRH group. Baseline characteristics, operative parameters, and postoperative complications of donors and recipients were compared between the two groups. Results Thirty patients underwent donor hepatectomy between the dates selected (9 PLDRH patients and 21 CODRH patients). The baseline characteristics of the 2 groups were not significantly different. The median graft volume of the PLDRH group was 693.8 mL, which was not significantly different from that of the CODRH group (726.5 mL) The PLDRH group had a longer operative time than the CODRH group, but the difference was not statistically significant (487.5 min vs 425.0 min, p = 0.197). The overall complication rate was not significantly different between the two groups (33.3% vs 22.2%, p = 0.555). Additionally, for the recipients, the incidence of major complications was not significantly different between the groups (71.3 vs 55.6%, p = 0.792). Conclusion Even in the context of this low-volume transplant program, whose staff have a high level of experience in minimally invasive hepatobiliary surgery, PLDRH showed similar results to CODRH in terms of perioperative outcomes for donors and recipients.

Abstract
Background Pure laparoscopic donor hepatectomy (PLDH) for adult living donor liver transplantation (LDLT) remains controversial. The aim of this study was to undertake a systematic review and meta-analysis of donor outcomes following PLDH for adult LDLT. Materials and Methods Systematic review in line with the meta-analysis of observational studies in epidemiology guidelines. Results Eight studies were included in the systematic review and six in the meta-analysis. A total of 575 donors underwent PLDH for adult LDLT. The mean donor age was 32.8 years with a BMI of 23.4 kg/m2 and graft weight of 675 g. The mean operative time was 353 min and the conversion rate was 2.8% (n = 16). Overall morbidity was 10.8% with 1.6% major complications (Clavien-Dindo grade 3b), zero mortality and 9.0 days length of stay (LOS). The meta-analysis demonstrated that the operative time was significantly shorter for the open donor hepatectomy group (mean difference 29.15 min; P = 0.006) and the LOS was shorter for the PLDH group (mean difference -0.73 days; P = 0.02), with a trend towards lesser estimated blood loss in PLDH group. However, no difference between the two groups was noted in terms of overall morbidity or major complications. Conclusions Perioperative outcomes of PLDH are similar to the standard open approach in highly specialised centers with trend towards lesser blood loss and overall shorter hospital stay. Careful donor selection and standardisation of the technique are imperative for the successful implementation and adoption of the procedure worldwide.

Abstract
BACKGROUND Having little evidence on the real extent of the minimally invasive donor hepatectomy (MIDH), a world survey was conducted aiming to picture the spread of MIDH and to identify geographical, institutional, and individual differences. METHODS A web-based survey was created with 5 sections (general, institutional, surgeon's experience, technical, and spread and dissemination), comprising up to a total of 47 questions. A thorough search was carried out to identify all possible centers and surgeons performing MIDH. RESULTS A global MIDH experience of 2370 cases was collected: 1587 right hepatectomies (RHs; 48.9% pure laparoscopic), 471 left lateral sectionectomies (LLS; 81.1% pure laparoscopic), and 366 left hepatectomies (LHs; 77.6% laparoscopic-assisted). LLS and adult MIDH conversion rates were 5.4% and 3.9%, respectively. Median blood loss was 250 mL (100-600), 100 mL (50-250), and 150 mL (50-500) for RH, LLS, and LH, respectively. Intra- and postoperative transfusion rates were 0.5%, 0%, and 0.3%; and 1.3%, 1.6%, and 0% for RH, LLS, and LH, respectively. Geographically, Asia accounts up to 1730 cases (73% of the global experience, 49.6% pure lap), of which 1374 cases are RH; Europe and Middle East-395 cases-stands out for its experience in left lateral sectionectomy: 289 cases (93% pure lap). Finally, America accounts for 245 cases, using a laparoscopic-assisted technique in 72.6% of the cases (178). CONCLUSIONS This world survey provides evidence and data on the global spread of MIDH and anticipates how in a near future a large-scale adoption of these techniques may be observed.

Abstract
Minimally invasive approaches are increasingly being applied in surgeries and have recently been used in living donor hepatectomy. We have developed a safe and reproducible method for minimally invasive living donor liver transplantation, which consists of pure laparoscopic explant hepatectomy and pure laparoscopic implantation of the graft, which was inserted through a suprapubic incision. Pure laparoscopic explant hepatectomy without liver fragmentation was performed in a 60-year-old man with alcoholic liver cirrhosis and hepatocellular carcinoma. The explanted liver was retrieved through a suprapubic incision. A modified right liver graft, procured from his 24-year-old son using the pure laparoscopic method, was inserted through a suprapubic incision, and implantation was performed intracorporeally throughout the procedure. The time required to remove the liver was 369 min, and the total operative time was 960 min. No complications occurred during or after the surgery. The patient recovered well, and his hospital stay was of 11 days. Pure laparoscopic living donor liver transplantation from explant hepatectomy to implantation was performed successfully. It is a feasible procedure when performed by a highly experienced surgeon and transplantation team. Further studies with larger sample sizes are needed to confirm its safety and feasibility.

Abstract
Living donation in many countries is the main resource of organs. Healthy, volunteering individuals deserve the highest safety standards possible in addition to the least invasive technique to procure the organs. Since the introduction of living donor liver transplantation, many efforts have been made to minimize the surgical trauma inherent to living donor surgery. The journey started with a large Mercedes incision and evolved to reverse L-shaped and small upper midline incisions before the introduction of minimally invasive laparoscopic techniques originated. The technical difficulties of the laparoscopic approach due to suboptimal instrumentation, challenging ergonomics, and the long learning curve limited the application of the fully laparoscopic approach to a few centers. The recent introduction of the robotic platform with its superb optical system and advanced instruments allows for the first time, a genuine emulation of open donor surgery in a closed abdomen, thus allowing all liver donors to benefit from minimally invasive surgery (better cosmesis, less pain and morbidity, and better quality of life) without compromising donor safety. This attribute in combination with the ubiquitous presence of the robot in major transplant centers may well lead to the desired endpoint of this technology, namely, the widespread dissemination of minimally invasive donor surgery.

[PMID: 34357530 DOI: 10.1007/s11605-020-04571-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/17/2020] [Accepted: 03/09/2020] [Indexed: 01/31/2023]
Abstract
BACKGROUND The use of laparoscopic liver resection (LLR) is widespread owing to its several advantages, especially smaller incision (Kaneko et al., Ann Gastroenterol Surg 1:33-43, 1; Ciria et al., Surg Endosc 34:349-360, 2). However, both posterior sectionectomy and donor hepatectomy are extremely difficult procedures to perform in LLR (Hasegawa et al., Ann Gastroenterol Surg 2:376-382, 3; Soubrane and Kwon, J Hepatobiliary Pancreat Sci 24:E1-E5, 4; Takahara et al., Transplantation 101:1628-1636, 5; Lee et al., Clin Transplant 33:e13683, 6; Hong et al., Surg Endosc 33:3741-3748, 7; Rhu et al., J Hepatobiliary Pancreat Sci 27:16-25, 8). Moreover, the right posterior section graft procurement is also difficult even in open laparotomy procedure (Sugawara et al., Transplantation 73:111-114, 9; Hwang et al., Liver Transpl 10:1150-1155, 10; Hori, Kirino, and Uemoto, Hepatol Res 45:1076-1082, 11; Kusakabe et al., Liver Transpl 26:299-303, 12). The pure laparoscopic donor posterior sectionectomy has not been reported yet. Therefore, we aimed to introduce a novel procedure through a video clip. METHODS The donor was placed in the semi-left lateral decubitus position with the reverse Trendelenburg position using a bean bag device. The right liver was mobilized, and the right hepatic vein was exposed. To adopt the liver hanging maneuver, a tape was inserted between the middle and right hepatic veins along the inferior vena cava. The posterior Glissonean pedicle was encircled and controlled, and the liver parenchyma was completely transected using the liver hanging maneuver. The vessels to the posterior section were respectively isolated. The posterior branches of the hepatic duct, hepatic artery, and portal vein were cut. The right hepatic vein was divided, and the graft liver was retrieved via a suprapubic incision. This study was approved by institutional ethics board (No. MH2019-119), and informed consent was taken from the patient. RESULTS The overall surgical time was 503 min, and the blood loss was 400 mL. No complications were observed, and the donor was discharged from the hospital on postoperative day 11. CONCLUSION This is the first report of pure laparoscopic donor hepatectomy of the posterior section graft. This procedure is more difficult than other laparoscopic donor hepatectomies because it involves parenchymal transection in the right intersectional plane and dissection of the posterior branches of hilar vessels.

A Novel Technique for Bile Duct Division During Laparoscopic Living Donor Hepatectomy to Overcome Biliary Complications in Liver Transplantation Recipients: "Cut and Clip" Rather Than "Clip and Cut". Transplantation 2021; 105:1791-1799. [PMID: 32826797 DOI: 10.1097/tp.0000000000003423] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
BACKGROUND This study was designed to analyze the clinical impact of a new bile duct division technique during laparoscopic living donor hepatectomy. METHODS Laparoscopic donor right hepatectomies performed by a single surgeon between December 2016 and August 2019 were included. Magnetic resonance cholangiopancreatography of the donors was reconstructed, and the length of the common channel of the dividing intrahepatic duct was measured. Patients were divided into 2 groups based on the bile duct division techniques of "clip and cut" versus "cut and clip." Outcome of bile duct division was categorized based on the graft and bile duct type and number of bile duct openings. RESULTS A total of 147 transplantations were included. Outcomes in the "cut and clip" group were better than those in the "clip and cut" group with regard to obtaining an adequate division point (94.2% versus 78.8%; P = 0.019). The "cut and clip" showed superior biliary stricture-free survival than the "clip and cut" group (hazard ratio [HR], 0.456; confidence interval [CI], 0.217-0.957; P = 0.038) whereas recipients with hepaticojejunostomy (HR, 3.358; CI, 1.090-10.350; P = 0.035) and bile duct type other than type I (HR, 2.214; CI, 1.143-4.289; P = 0.018) showed increased risk for biliary stricture-free survival. Better outcome in terms of obtaining a single opening was also obtained in the "cut and clip" group (68.2% versus 84.6%; P = 0.040), and this difference was significant especially with a common channel shorter than 10 mm (45.5% versus 81.2%; P = 0.043). CONCLUSIONS The "cut and clip" technique showed superior outcomes to the "clip and cut" technique in terms of fewer bile duct openings and biliary stricture-free survival of the recipients.

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.

J Gastrointest Surg 2021; 25:1980-1988. [PMID: 33104954 DOI: 10.1007/s11605-020-04837-7] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2020] [Accepted: 10/17/2020] [Indexed: 01/31/2023]
Abstract
BACKGROUND Depending on a transplant center's level of experience, utilization of pure laparoscopic donor right hepatectomy (PLDRH) may be limited due to graft size or anatomical variations. Here, we aimed to evaluate the influence of large hepatic grafts (≥ 1000 g) when performing PLDRH in both donors and recipients of such grafts. METHODS Medical records of living donors who underwent either PLDRH from November 2015 to August 2019 or open conventional donor right hepatectomy (CDRH) from January 2010 to August 2019 and those of the graft recipients were retrospectively reviewed. Donors were separated into three groups: PLDRH graft ≥ 1000 g (n = 10; study group), PLDRH graft < 1000 g (n = 280; control-I group), and CDRH graft ≥ 1000 g (n = 24; control-II group). RESULTS Total operative duration (P = 0.017) and warm ischemia time (P < 0.001) were significantly longer in the study than in the control-I and control-II groups, respectively. ΔAlanine aminotransferase% was significantly lower in the study than in the control-I group (P = 0.001). There was no significant difference in minor complication incidence between the study and control-I (P = 0.068) and control-II (P = 0.618) donors. There were no major complications in the study and control-II donors, whereas six control-I donors (2.1%) experienced a major complication (P = 1.000). Length of hospitalization was significantly shorter in the study than in the control-II group (P < 0.001). There was no significant difference in early and late major complication incidence for recipients between the study and control-I and control-II groups. CONCLUSIONS PLDRH for grafts weighing ≥ 1000 g appears to be safe and feasible when performed by experienced surgeons in a well-equipped center.

Abstract
BACKGROUND This study evaluated the timing of safe introduction of total laparoscopic donor right hepatectomy (TLDRH) based on outcomes of laparoscopic major hepatectomy (LMH). METHODS The data of 1013 consecutive patients who underwent laparoscopic liver resection from 2003 to 2017 were reviewed; the cumulative sum method was used to evaluate the learning curve of LMH. Patients were divided into 3 groups according to the timing of introduction of TLDRH (since 2010) and learning curve of LMH. Surgical outcomes of LMH and TLDRH were evaluated. RESULTS Cumulative sum analysis demonstrated a learning curve of approximately 73 cases of LMH. In phase I (before the introduction of TLDRH, 2003-2009), 38 cases of LMH were performed. Phase II (after the introduction of TLDRH until learning curve of LMH, 2010-2014), 35 and 15 cases of LMH and TLDRH were performed, respectively. Phase III (after learning curve of LMH until 2017, 2014-2017), 59 and 20 cases of LMH and TLDRH were performed, respectively. In cases of LMH, there was significant improvement in the operation time 398.9 ± 140.9 versus 403.7 ± 165.2 versus 265.5 ± 91.7; P < 0.001), estimated blood loss (1122.9 ± 1460.2 versus 1209.3 ± 1409.1 versus 359.8 ± 268.8; P < 0.001), and open conversion rate (26.3% versus 22.9% versus 13.6%; P = 0.026) between phases I versus II versus III. In cases of TLDRH, the operation time (567.8 ± 117.9 versus 344.2 ± 71.8; P < 0.001), estimated blood loss (800.7 ± 514.8 versus 439.4 ± 347.0; P = 0.004), and hospital stay (12.5 ± 4.36 versus 9.15 ± 4.84; P = 0.025) significantly improved in phase III. CONCLUSIONS Overcoming the learning curve of LMH before starting TLDRH is advisable to ensure donor's surgical outcomes.

Abstract
The laparoscopic living-donor hepatectomy procedure has been developing rapidly. Although its use has increased worldwide, it is still only performed by experienced surgeons at a limited number of institutions. However, technical innovations have improved the feasibility of more widespread use of laparoscopic living-donor hepatectomy. The advantages of laparoscopic living-donor hepatectomy should not be overemphasized, and the fundamental principle of "living-donor safety first" cannot be neglected. This review aims to summarize the current status of laparoscopic living-donor hepatectomy and to emphasize that, while this procedure may soon be used as a reliable, donor-friendly substitute for traditional open donor hepatectomy, its safety and efficacy require further substantiation first.

Abstract
BACKGROUND Thoracoscopic repair of esophageal atresia with tracheoesophageal fistula (EA/TEF) remains technically challenging due to the rarity of these procedures. The aim of this study is to report our experience with thoracoscopic repair of type C EA/TEF and to evaluate the learning curve based upon the surgeon's skill level. METHODS We retrospectively reviewed data of thoracoscopic EA/TEF repair performed in our center between October 2008 and May 2019. The learning curve was evaluated using the cumulative sum (CUSUM) method based on operative time. RESULTS Of the 50 consecutive cases evaluated, the mean birth weight was 2634 ± 608 g and the median age at operation was 3 days (range, 1-29 days). The mean operation time was 144 ± 65 min. Anastomosis leakage occurred in 3 cases (6%) and strictures requiring balloon dilatations occurred in 16 cases (32%). The CUSUM analysis evaluated a learning curve of approximately 10 cases of thoracoscopic type C EA/TEF repair. A lower gestational age was associated with longer operation time. CONCLUSIONS Thoracoscopic repair of type C EA/TEF is a feasible and safe procedure. The number of procedures required to achieve a stable learning curve was 10. The learning phase may be shortened by adequate set-up under the supervision of an expert endoscopic surgeon. TYPE OF STUDY Retrospective Comparative Treatment Study. LEVEL OF EVIDENCE III.

Anterior approach for pure laparoscopic donor right hepatectomy. Surg Endosc 2020; 34:4677-4678.

Abstract
BACKGROUND Pure laparoscopic donor hepatectomy (PLDH) is being increasingly performed at centers with experienced surgeons [1-6]. This procedure is still developing and is associated with several challenges owing to its technical difficulty [7-9]. Conversely, the anterior approach is sometimes applied to both laparoscopic and open right hepatectomy for management of tumors in the liver [10, 11]. However, there are no reports regarding the use of the anterior approach for PLDH. We found this method to be useful; therefore, we aimed to introduce the novel procedure using a video clip. METHODS The donor was placed in the supine position. First, the right side of the inferior vena cava was dissected instead of performing the liver hanging maneuver. The right Glissonean pedicle was encircled and controlled, and the liver parenchyma was completely transected. Thereafter, the ligaments around the liver were dissected, and the graft was mobilized. The hilar vessels were respectively separated. Finally, the right hepatic duct, right hepatic artery, right portal vein, and right hepatic vein were divided, and the graft liver was retrieved. This study was approved by institutional ethics board (MH2019-119), and informed consent was taken from the patient. RESULTS The overall surgical time was 400 min, the volume of blood loss was 31 mL, the warm ischemic time was 7 min, and no complications were seen. CONCLUSION The advantages of the anterior approach for right-sided PLDH might be attribute to reduction of compression injury and incidence of subcapsular hematoma, as liver mobilization is easily performed because of increased liver mobility. However, PLDH is a highly-skilled procedure, and indications for PLDH should be extended in a step-wise manner. Further, the procedure should be performed only by highly proficient surgeons having extensive experience in both laparoscopic liver resection and living donor liver transplantation.

Abstract
Laparoscopic liver resection was slow to be adopted in the surgical arena at the beginning as there were major barriers including the fear of gas embolism, risk of excessive blood loss from the inability to control bleeding vessels effectively, suboptimal surgical instruments to perform major liver resection and the concerns about oncological safety of the procedure. However, it has come a long way since the early 1990s when the first successful laparoscopic liver resection was performed, spurring liver surgeons worldwide to start exploring the roles of laparoscopy in major liver resections. Till date, more than 9000 cases have been reported in the literature and the numbers continue to soar as the hepatobiliary surgical communities quickly learn and apply this technique in performing major liver resection. Large bodies of evidence are available in the literature showing that laparoscopic major liver resection can confer improved short-term outcomes in terms of lesser operative morbidities, lesser operative blood loss, lesser post-operative pain and faster recovery with shorter length of hospitalization. On the other hand, there is no compromise in the long-term and oncological outcomes in terms of comparable R0 resection rate and survival rates of this approach. Many innovations in laparoscopic major hepatectomies for complex operations have also been reported. In this article, we highlight the journey of laparoscopic major hepatectomies, summarize the technical advancement and lessons learnt as well as review the current standards of outcomes for this procedure.

Abstract
Liver transplantation is a life-saving therapy for patients with end-stage liver disease. Living donation is a critical source of organs throughout the world. Reducing donor morbidity and mortality is of utmost importance while maintaining access to liver transplantation for recipients. While laparoscopy was more rapidly utilized in donor nephrectomy, laparoscopy has been slower to develop for living donor hepatectomies due to the concerns about hemostasis, safety of the donor and quality of the graft. Pure minimal invasive approach has become a standard of care for left lateral sectionectomy (LLS) for pediatric recipients. In the past few years, a number of centers with significant laparoscopic and living donor experience have reported fully minimally invasive approach to hemi-hepatectomies. In this manuscript we discuss the experiences, lessons learned and path forward for laparoscopic and minimal invasive surgery(MIS) in donor hepatectomies (DH).

Abstract
In spite of early adoption of the brain death legislation, and all efforts at promoting deceased donation, various social, economic and cultural factors have acted as road blocks to the furthering of deceased donor liver transplantation (DDLT) in most Asian societies. On the other hand, Asian liver transplant centers have been the pioneers, innovators, and technical advancement catalysts for the world to follow, especially with regards to living donor liver transplantation (LDLT). With some high volume centers performing more than 200 LDLTs a year with good outcomes in the donor and recipient, techniques to expand the living donor pool have also been adopted like ABO-incompatible, paired exchange and dual lobe living donor liver transplants. Although large multicenter, and registry data as regards safety and outcomes of minimally invasive donor hepatectomy are awaited, expert centers have pioneered, and now regularly perform purely laparoscopic and robotic living donor hepatectomies, especially in Korea.

Abstract
Background Pure laparoscopic donor right hepatectomy (PLDRH) for donors with obesity has not been previously investigated. This study aimed to investigate the influence of donor obesity (BMI ≥30 kg/m2) on and clinical outcomes after PLDRH. Material/Methods Records of all living donors who underwent PLDRH between November 2015 and May 2018 and open conventional donor right hepatectomy (CDRH) between January 2011 and October 2015 at Seoul National University Hospital were retrospectively reviewed. The donors were divided into 3 groups: PLDRH BMI ≥30, PLDRH BMI <30, and CDRH BMI ≥30. Results Donors in the PLDRH BMI ≥30 group (n=7) were compared with those in the PLDRH BMI <30 (n=65; control 1) and CDRH BMI ≥30 (n=8; control 2) groups. Graft weight was significantly heavier in PLDRH BMI ≥30 than in control 1 (P=0.012). The lowest hemoglobin (Hb) value was higher (P=0.014) and ΔHb% was lower (P=0.005) in PLDRH BMI ≥30 than in control 1. Similarly, the lowest Hb value was higher (P=0.021) and ΔHb% was lower (P<0.001) in PLDRH BMI ≥30 than in control 2. The peak alanine aminotransferase (ALT) (P=0.029) and ΔALT% were higher in PLDRH BMI ≥30 than in control 2. No significant differences in hospital stay and postoperative complications were found between PLDRH BMI ≥3 and control 1, as well as between PLDRH BMI ≥3 and control 2. Conclusions This study revealed that PLDRH is feasible in donors with obesity.
