Precision surgery for primary liver cancer

Liver resection remains the best curative option for primary liver cancer, such as hepatocellular carcinoma(HCC) and intrahepatic cholangiocarcinoma.In particular, in liver resection for HCC, anatomical resection of the tumor-bearing segments is highly recommended to eradicate the intrahepatic metastases spreading through portal venous branches.Anatomical liver resection,including anatomical segmentectomy and subsegmentectomy using the dye-injection method, is technically demanding and requires experience for completion of a precise procedure.The recent development of imaging studies and new computer technologies has allowed for the preoperative design of the operative procedure, intraoperative navigation, and postoperative quality evaluation of the anatomical liver resection.Although these new technologies are related to the progress of artificial intelligence, the actual operative procedure is still performed as human-hand work.A precise anatomical liver resection still requires meticulous exposure of the boundary of hepatic venous tributaries with deep knowledge of liver anatomy and utilization of intraoperative ultrasonography.

Anatomic isolated caudate lobectomy: Is it possible to establish a standard surgical flow?

AIM To establish the surgical flow for anatomic isolated caudate lobe resection. METHODS The study was approved by the ethics committee of the Second Affiliated Hospital Zhejiang University School of Medicine(SAHZU). From April 2004 to July 2014, 20 patients were enrolled who underwent anatomic isolated caudate lobectomy at SAHZU. Clinical and postoperative pathological data were analyzed. RESULTS Of the total 20 cases, 4 received isolated complete caudate lobectomy(20%) and 16 received isolated partial caudate lobectomy(80%). There were 4 caseswith the left approach(4/20, 20%), 6 cases with the right approach(6/20, 30%), 7 cases with the bilateral combined approach(7/20, 35%), 3 cases with the anterior approach(3/20, 15%), and the hanging maneuver was also combined in 2 cases. The median tumor size was 5.5 cm(2-12 cm). The median intraoperative blood loss was 600 m L(200-5700 m L). The median intra-operative blood transfusion volume was 250 m L(0-2400 m L). The median operation time was 255 min(110-510 min). The median post-operative hospital stay was 14 d(7-30 d). The 1-and 3-year survival rates for malignant tumor were 88.9% and 49.4%, respectively. CONCLUSION Caudate lobectomy was a challenging procedure. It was demonstrated that anatomic isolated caudate lobectomy can be done safely and effectively.

Tailored classification of portal vein thrombosis for liver transplantation:Focus on strategies for portal vein inflow reconstruction

Portal vein thrombosis(PVT)is currently not considered a contraindication for liver transplantation(LT),but diffuse or complicated PVT remains a major surgical challenge.Here,we review the prevalence,natural course and current grading systems of PVT and propose a tailored classification of PVT in the setting of LT.PVT in liver transplant recipients is classified into three types,corresponding to three portal reconstruction strategies:Anatomical,physiological and non-physiological.Type I PVT can be removed via low dissection of the portal vein(PV)or thrombectomy;porto-portal anastomosis is then performed with or without an interposed vascular graft.Physiological reconstruction used for type II PVT includes vascular interposition between mesenteric veins and PV,collateral-PV and splenic vein-PV anastomosis.Non-physiological reconstruction used for type III PVT includes cavoportal hemitransposition,renoportal anastomosis,portal vein arterialization and multivisceral transplantation.All portal reconstruction techniques were reviewed.This tailored classification system stratifies PVT patients by surgical complexity,risk of postoperative complications and long-term survival.We advocate using the tailored classification for PVT grading before LT,which will urge transplant surgeons to make a better preoperative planning and pay more attention to all potential strategies for portal reconstruction.Further verification in a large-sample cohort study is needed.

Living donor liver hilar variations: surgical approaches and implications

BACKGROUND: Varied vascular and biliary anatomies are common in the liver. Living donor hepatectomy requires precise recognition of the hilar anatomy. This study was undertaken to study donor vascular and biliary tract variations, surgical approaches and implications in living liver transplant patients. METHODS: Two hundred living donor liver transplantations were performed at our institution between 2004 and 2009. All donors were evaluated by volumetric computerized tomography (CT), CT angiography and magnetic resonance cholangiography in the preoperative period. Intraoperative ultrasonography and cholangiography were carried out. Arterial, portal and biliary anatomies were classified according to the Michels, Cheng and Huang criteria. RESULTS: Classical hepatic arterial anatomy was observed in 129 (64.5%) of the 200 donors. Fifteen percent of the donors had variation in the portal vein. Normal biliary anatomy was found in 126 (63%) donors, and biliary tract variation in 70% of donors with portal vein variations. In recipients with single duct biliary anastomosis, 16 (14.4%) developed biliary leak, and 9 (8.1%) developed biliary stricture; however more than one biliary anastomosis increased recipient biliary complications. Donor vascular variations did not increase recipient vascular complications. Variant anatomy was not associated with an increase in donor morbidity. CONCLUSIONS: Living donor liver transplantation provides information about variant hilar anatomy. The success of the procedure depends on a careful approach to anatomical variations. When the deceased donor supply is inadequate, living donor transplantation is a life-saving alternative and is safe for the donor and recipient, even if the donor has variant hilar anatomy.

Prospective validation to prevent symptomatic portal vein thrombosis after liver resection

BACKGROUND Portal vein thrombosis(PVT)after liver resection is rare but can lead to lifethreatening liver failure.This prospective study evaluated patients using contrastenhanced computed tomography(E-CT)on the first day after liver resection for early PVT detection and management.AIM To evaluate patients by E-CT on the first day after liver resection for early PVT detection and immediate management.METHODS Patients who underwent liver resection for primary liver cancer from January 2015 were enrolled.E-CT was performed on the first day after surgery in patients undergoing anatomical resection,multiple resections,or with postoperative bile leakage in the high-risk group for PVT.When PVT was detected,anticoagulant therapy including heparin,warfarin,and edoxaban was administered.E-CT was performed monthly until PVT resolved.RESULTS The overall incidence of PVT was 1.57%(8/508).E-CT was performed on the first day after surgery in 235 consecutive high-risk patients(165 anatomical resections,74 multiple resections,and 28 bile leakages),with a PVT incidence of 3.4%(8/235).Symptomatic PVT was not observed in the excluded cohort.Multivariate analyses revealed that sectionectomy was the only independent predictor of PVT[odds ratio(OR)=12.20;95%confidence interval(CI):2.22-115.97;P=0.003].PVT was found in the umbilical portion of 75.0%(6/8)of patients,and sectionectomy on the left side showed the highest risk of PVT(OR=14.10;95%CI:3.17-62.71;P<0.0001).CONCLUSION Sectionectomy on the left side should be chosen with caution as it showed the highest risk of PVT.E-CT followed by anticoagulant therapy was effective in managing early-phase PVT for 2 mo without adverse events.

Novel techniques of liver segmental and subsegmental pedicle anatomy from segment 1 to segment 8

BACKGROUND Laparoscopic anatomical liver resection has become more challenging because some subsegmental Glissonean pedicles are hard to dissect.Here,we introduce how to dissect every(sub)segmental Glissonean pedicle from the first porta hepatis and perform standardized(sub)segmentectomy[from segment 1(S1)to S8].AIM To summarize our methods of laparoscopic anatomical segmental and subseg-mental liver resection.METHODS The Glisson sheath and liver capsule were separated along the Laennec mem-brane.The Glissonean pedicle could be isolated and transected with little or no parenchymal damage through this extra-Glissonean dissection approach.The basin of the(sub)segment was determined by the ischemia demarcation line or indocyanine green staining.The hepatic vein or intersegmental vein was also used to guide the plane of parenchymal transection.RESULTS All segmental or subsegmental pedicles or even the pedicle of the cone unit could be dissected along the Laennec membrane using our novel technique through the first porta hepatis.The dorsal branches of S8,the branches of S4a and the paracaval portion branches(b/c vein)of the caudate lobe were the most difficult to dissect.CONCLUSION The novel techniques of liver segmental and subsegmental pedicle anatomy is feasible for laparoscopic liver resection and can help accurately guide(sub)segmentectomy from S1 to S8.

Retrospective Cohort Study Laparoscopic anatomical SVIII resection via middle hepatic fissure approach:Caudal or cranio side

BACKGROUND Laparoscopic hepatectomy is a proven safe and technically feasible approach for liver tumor resection,but laparoscopic anatomical SVIII resection(LASVIIIR)remains rarely reported due to poor accessibility,difficult exposure,and the deep-lying Glissonean pedicle.This study examined the safety,feasibility,and perio-perative outcomes of LASVIIIR via a middle hepatic fissure approach at our in-stitution.AIM To investigate the safety,feasibility,and perioperative outcomes of LASVIIIR via a middle hepatic fissure approach at our institution.METHODS From November 2017 to December 2022,all patients with a liver tumor who underwent LASVIIIR were enrolled.The perioperative outcomes and postope-rative complications were evaluated.RESULTS Thirty-four patients underwent LASVIIIR via a middle hepatic fissure approach from the side or cranio side and were included.The mean operation time was 164±54 minutes,and the intra-operative blood loss was 100 mL(range:20-1000 mL).The mean operative times were,respectively,152±50 minutes and 222±29 minutes(P=0.001)for the caudal side and cranial side approaches.In addition,the median blood loss volumes were 100 mL(range:20-300 mL)and 250 mL(range:20-1000 mL),respectively,for the caudal and cranial sides(P=0.064).Three patients treated using the cranial side approach experienced bile leakage,while 1 patient treated using the caudal side approach had subphrenic collection and underwent percutaneous drainage to successfully recover.There were no differences regarding postoperative hospital stays for the caudal and cranial side approaches[9(7-26)days vs 8(8-19)days](P=0.226).CONCLUSION LASVIIIR resection remains a challenging operation,but the middle hepatic fissure approach is a reasonable and easy-to-implement technique.

Surgical experience in splitting donor liver into left lateral and right extended lobes

AIM： To outline the surgical experience with donor liver splitting in split liver transplantation.METHODS： From March 1 to September 1 in 2004, 10 donor livers were split ex situ into a left lateral lobe （segments Ⅱ and Ⅲ） and a right extended lobe （segments Ⅰ, Ⅳ-Ⅷ） in Medical School of Hannover, and thereafter split liver transplantation was performed successfully in 29 cases. The average age, weight and ICU slaying period of the donors were 32.7 years （25-52 years）, 64.5 kg（45-75 kg） and 2.4 d （2-8 d） respectively.RESULTS： The average weight of the whole graft and the left lateral lobe was 2 322.6 g （956-2 665 g） and 282.8 g （298-373 g） respectively, and the average ratio of left lateral lobe to the whole graft was 0.225 （0.278-0.274）.The average graft to recipient weight ratio （GRWR） of the left lateral lobe and the right extended lobe reached 2.44% （2.22-5.42%） and 2.73% （2.32-2.30%） respectively.On average it took approximately 205 min （85-235 rain）to split the donor liver. Five donor organs showed anatomic variation including the left hepatic vein variation in two cases, the left hepatic artery variation in two cases and the bile duct variation in one case.CONCLUSION： Split liver transplantation has become a mature surgical technique to expand the donor pool with promising results. In the process of graft splitting, close attention needs to be paid to potential anatomic variations,especially to variations of the left hepatic vein, the left hepatic artery, and the bile duct.

Large Riedel’s lobe and atrophic left liver in a donor-Accept for transplant or call off?

BACKGROUND In context of suboptimal liver utilisation,grafts with various risk factors are under consideration today.For example,impaired vascularity with severe arterial calcifications and modified liver shapes are no longer contraindications and their use depends on the centre policy and experience of the surgical team.Riedel liver lobes represent a tongue-like liver shape with inferior projection in the right liver lobe.Such development modifications were initially described when patients developed a lesion and subsequently presented with symptoms.We here present the first case report in the literature,where such livers with anatomical variations were used for transplantation.CASE SUMMARY We describe here two cases of adult human liver transplantation,where we have accepted two donor livers with modified shape.The technical considerations for transplantation of such livers,found with enlarged right lobes,or Riedel shape,and hypo-trophic left lateral segment are highlighted.Both recipients experienced immediate liver function and overall good outcomes with a minimum follow up of 1 year.We also provide detailed pictures and outcome analysis in combination with a literature review.CONCLUSION The utilisation of donor livers with modified shape,such as Riedel’s Lobe appears safe and will increase the donor pool.
