Short-term Outcomes of Laparoscopic Versus Open Liver Resection in the Elderly: A Propensity Score-matched Analysis.

BACKGROUND/AIM: With the aging of the population, there is a rising proportion of elderly patients undergoing liver resection. However, the safety and efficacy of laparoscopic liver resection (LLR) in the elderly have not yet been established. In this study, we compared the short-term results of LLR and open liver resection (OLR) in elderly patients using propensity score matched (PSM) analysis. PATIENTS AND METHODS: The study comprised 237 elderly patients aged 65 years and older who had undergone liver resection between 2015 to 2021, excluding biliary and vascular reconstruction and simultaneous surgeries other than liver resection. We conducted PSM analysis for baseline characteristics (age, sex, BMI, ASA-PS, disease, procedure, tumor size, and number of tumors) to eliminate potential selection bias. We then compared short-term postoperative outcomes between LLR and OLR groups in patients selected by PSM analysis. RESULTS: Applying PSM analysis, 90 cases each were selected for the LLR and OLR groups. The LLR group had a significantly lower complication rate (Clavien-Dindo: CD ≥II) (19% vs. 33%, p=0.03), especially bile leakage (CD ≥II) (0% vs. 6.7%, p=0.03) compared with those in the OLR group. In addition, a shorter operation time (244 min vs. 351 min, p<0.01), less blood loss (150 ml vs. 335 ml, p<0.01), and shorter hospital stay (8 days vs. 12 days, p<0.01) were observed in the LLR group. No operative or in-hospital deaths were observed in both groups. CONCLUSION: LLR can be safely performed in elderly patients and offers better short-term outcomes.

Prognostic impact of osteosarcopenia in patients undergoing pancreatic resection for pancreatic ductal adenocarcinoma.

BACKGROUND: We investigated the prognostic impact of osteosarcopenia, defined as the combination of osteopenia and sarcopenia, in patients undergoing pancreatic resection for pancreatic ductal adenocarcinoma (PDAC). METHODS: The relationship of osteosarcopenia with disease-free survival and overall survival was analyzed in 183 patients who underwent elective pancreatic resection for PDAC. Computed tomography was used to measure the pixel density in the midvertebral core of the 11th thoracic vertebra for evaluation of osteopenia and in the psoas muscle area of the 3rd lumbar vertebra for evaluation of sarcopenia. Osteosarcopenia was defined as the simultaneous presence of both osteopenia and sarcopenia. The study employed a retrospective design to examine the relationship between osteosarcopenia and survival outcomes. RESULTS: Osteosarcopenia was identified in 61 (33%) patients. In the univariate analysis, disease-free survival was significantly worse in patients with male sex (p = 0.031), pathological stage ≥ III PDAC (p = 0.001), NLR, ≥ 2.71 (p = 0.041), sarcopenia (p = 0.027), osteopenia (p = 0.001), and osteosarcopenia (p < 0.001), and overall survival was significantly worse in patients with male sex (p = 0.001), pathological stage ≥ III PDAC (p = 0.001), distal pancreatectomy (p = 0.025), sarcopenia (p = 0.003), osteopenia (p < 0.001), and osteosarcopenia (p < 0.001). In the multivariate analysis, the independent predictors of disease-free survival were osteosarcopenia (p < 0.001) and pathological stage ≥ III PDAC (p = 0.002), and the independent predictors of overall survival were osteosarcopenia (p < 0.001), male sex (p = 0.006) and pathological stage ≥ III PDAC (p = 0.001). CONCLUSION: Osteosarcopenia has an adverse prognostic impact on long-term outcomes in patients undergoing pancreatic resection for PDAC.

Strategies to Perform Emergency Laparoscopic Partial Liver Resection for Ruptured Hepatocellular Carcinoma.

BACKGROUND/AIM: Laparoscopic hepatic resection is currently used for ruptured hepatocellular carcinoma (HCC); however, it is technically challenging. We developed and implemented surgical strategies for emergency laparoscopic partial liver resection in selected patients with peripheral lesions who were hemodynamically stable and without severe liver dysfunction. PATIENTS AND METHODS: The surgical techniques used were as follows. First, the Pringle maneuver was performed to control hepatic blood inflow (step 1). Next, strong hemostatic agents were applied at the rupture point of the tumor (step 2). The hanging tape was positioned along the dorsal side of the resection line to control the partial blood inflow and outflow of the tumor, as well as to expose the surgical plane (step 3). The liver parenchyma was dissected along the hanging tape (step 4). We performed emergency laparoscopic partial liver resection in three patients who were in a pre-shock status. RESULTS: The tumors were located in segments 6 (cases 1 and 2) and 2 (case 3). The tumor diameters were 90, 62, and 80 mm. The Preoperative Child-Pugh scores were B7, B9, and B8. The hemostatic products performed well and controlled bleeding from the ruptured HCC. The hanging tape facilitated the dissection of the liver parenchyma. The operative time and intraoperative blood loss were 135 min and 400 ml, 266 min and 200 ml, and 191 min and 495 ml for cases 1, 2, and 3 respectively. There were no in-hospital deaths. CONCLUSION: Emergency laparoscopic partial liver resection could be an option for patients with ruptured HCC.

The Signal Intensity Ratio of Pancreas to Spleen in Magnetic Resonance Imaging Can Predict Nonalcoholic Fatty Liver Disease After Pancreaticoduodenectomy.

OBJECTIVES: Signal intensity ratio of pancreas to spleen (SI ratio p/s ) on fat-suppressed T1-weighted images of magnetic resonance imaging has been associated with pancreatic exocrine function. We here investigated the predictive value of the SI ratio p/s for the development of nonalcoholic fatty liver disease (NAFLD) after pancreaticoduodenectomy (PD). MATERIALS AND METHODS: This study comprised 208 patients who underwent PD. NAFLD was defined as a liver-to-spleen attenuation ratio of <0.9 calculated by a computed tomography 1 year after surgery. SI ratio p/s was calculated by dividing the average pancreas SI by the spleen SI. We retrospectively investigated the association of clinical variables including the SI ratio p/s and NAFLD by univariate and multivariate analyses. RESULTS: NAFLD after 1 year was developed in 27 patients (13%). In multivariate analysis, the SI ratio p/s < 1 ( P < 0.001) was an independent predictor of incidence of NAFLD. The SI ratio p/s < 1 was associated with low amylase level of the pancreatic juice ( P < 0.001) and progressed pancreatic fibrosis ( P = 0.017). According to the receiver operating characteristics curve, the SI ratio p/s had better prognostic ability of NAFLD than the remnant pancreas volume. CONCLUSIONS: The SI ratio p/s is useful to predict NAFLD development after PD. Moreover, the SI ratio p/s can be a surrogate marker, which represents exocrine function of the pancreas.

Analysis of Preoperative Risk Factors for Early Recurrence in Patients After Hepatic Resection for Intrahepatic Cholangiocarcinoma.

BACKGROUND: Intrahepatic cholangiocarcinoma (ICC) has a poor prognosis even after curative-intent hepatic resection due to a high recurrence rate. The aim of this study was to investigate preoperative risk factors for early recurrence after surgery for ICC, which may help to identify patients who need preoperative chemotherapy. METHODS: We retrospectively analyzed 51 patients who had undergone primary surgery for ICC. We investigated the association of preoperative clinical variables with recurrence within 1 year after resection for ICC. We then created a high-risk ICC score using the identified preoperative factors and investigated the association of the score with disease-free and overall survival. RESULTS: Recurrence within 1 year after surgery for ICC was significantly associated with poor overall survival (P < .01). In the multivariate analysis, preoperative tumor size > 5 cm (P = .03) and elevated C-reactive protein-to-albumin ratio (CAR) (P = .04) were significantly associated with recurrence within 1 year after surgery. A high-risk ICC score of 2 was associated with poor disease-free survival (P < .01) and overall survival (P = .02) compared with a score of 0 or 1. CONCLUSIONS: Our high-risk ICC score, combining preoperative tumor size and CAR, can be an indicator of early recurrence and poor survival in patients after hepatic resection for ICC. Our findings may provide better preoperative risk stratification of patients with ICC, and the high-risk ICC patients may benefit from preoperative therapy.

The prognosis-based classification model in resectable pancreatic cancer.

AIM: Pancreatic ductal adenocarcinoma treatment is mainly based on the anatomical resectability classification. However, prognosis-based classification may be more reasonable. In this study, we stratified resectable pancreatic ductal adenocarcinoma according to preoperative factors and reconsidered treatment strategies. METHODS: We retrospectively evaluated 131 patients who underwent upfront surgery for resectable pancreatic ductal adenocarcinoma between 2007 and 2019. Recurrence within 1 year after surgery was defined as early recurrence, and the risk factors for early recurrence were identified using preoperative factors. Subsequently, we calculated the scores and stratified the participant groups. RESULTS: Fifty-five (42 %) patients who relapsed within 1 year showed significantly poorer survival than those without recurrence (median overall survival, 14.0 vs. 80.6 months; p < 0.01). Multivariate analysis revealed that a tumor diameter of ≥24 mm (p < 0.01) and preoperative serum carbohydrate antigen 19-9 level of ≥380 U/mL (p = 0.04) were the independent risk factors for early recurrence. Early recurrence score was created using these factors, stratifying the participant group into three groups of 0-2 points, and the prognosis was significantly different (median overall survival, 49.3 vs. 31.2 vs. 16.0 months; p < 0.01). CONCLUSION: We stratified the upfront surgical cases of resectable pancreatic ductal adenocarcinoma. The group with a score of 0 had a good prognosis, and upfront surgery was possibly not futile on patients in poor general condition. The group with a score of 2 had a poor prognosis and may require stronger preoperative treatment.

Prognostic significance of occult vertebral fracture in patients undergoing pancreatic resection for pancreatic cancer.

OBJECTIVE: The prognostic impact of occult vertebral fracture (OVF) in patients with malignancies is a new cutting edge in cancer research. This study was performed to analyze the prognostic impact of OVF after surgery for pancreatic cancer. METHODS: This study involved 200 patients who underwent surgical treatment of pancreatic ductal adenocarcinoma. OVF was diagnosed by quantitative measurement using preoperative sagittal computed tomography image reconstruction from the 11th thoracic vertebra to the 5th lumbar vertebra. RESULTS: OVF was diagnosed in 65 (32.5 %) patients. The multivariate analyses showed that male sex (p = 0.01), osteopenia (p < 0.01), OVF (p < 0.01), a carbohydrate antigen 19-9 level of ≥400 U/mL (p < 0.01), advanced stage of cancer (p < 0.01), and non-adjuvant chemotherapy (p = 0.02) were independent risk factors for overall survival. An age of ≥74 years (p < 0.01) and obstructive jaundice (p = 0.03) were independent risk factors for OVF. Furthermore, the combination of OVF and osteopenia further worsened disease-free survival and overall survival compared with osteopenia or OVF alone (p < 0.01; respectively). CONCLUSION: Evaluation of preoperative OVF might be a useful prognostic indicator for patients with pancreatic ductal adenocarcinoma.

Systemic inflammation adversely affects response to anamorelin in patients with pancreatic cancer.

PURPOSE: Anamorelin, a selective ghrelin receptor agonist, has been approved for pancreatic cancer treatment in Japan. We aimed to investigate whether systemic inflammation, represented by the neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), lymphocyte-monocyte ratio (LMR), and C-reactive protein (CRP)-albumin ratio (CAR), could predict the effect of anamorelin in patients with advanced pancreatic cancer. METHODS: This study included 31 patients who had received anamorelin for advanced pancreatic cancer between 2021 and 2023. Patients' NLR, PLR, LMR, and CAR were evaluated before anamorelin administration. The patients were classified as responders and non-responders based on whether they gained body weight after 3 months of anamorelin administration. We investigated the association between systemic inflammation and anamorelin efficacy using a univariate analysis. RESULTS: Twelve (39%) patients were non-responders. A high serum CRP level (p = 0.007) and high CAR (p = 0.013) was associated with non-response to anamorelin. According to the receiver operating characteristics analysis, the CAR cutoff value was 0.06, and CAR ≥ 0.06 was a risk factor (odds ratio, 5.6 [95% confidence interval 1.2-27.1], p = 0.032) for non-response to anamorelin. CONCLUSION: CAR can be a predictor of non-response to anamorelin in patients with advanced pancreatic cancer, suggesting the importance of a comprehensive assessment of the inflammatory status.

A feasible and safe approach for repeat laparoscopic liver resection and patient selection based on standardized preoperative prediction of surgical difficulty.

PURPOSE: This study was performed to propose a strategy for repeat laparoscopic liver resection (RLLR) and investigate the preoperative predictive factors for RLLR difficulty. METHODS: Data from 43 patients who underwent RLLR using various techniques at 2 participating hospitals from April 2020 to March 2022 were retrospectively reviewed. Surgical outcomes, short-term outcomes, and feasibility and safety of the proposed techniques were evaluated. The relationship between potential predictive factors for difficult RLLR and perioperative outcomes was evaluated. Difficulties associated with RLLR were analyzed separately in two surgical phases: the Pringle maneuver phase and the liver parenchymal transection phase. RESULTS: The open conversion rate was 7%. The median surgical time and intraoperative blood loss were 235 min and 200 mL, respectively. The Pringle maneuver was successfully performed in 81% of patients using the laparoscopic Satinsky vascular clamp (LSVC). Clavien-Dindo class ≥III postoperative complications were observed in 12% of patients without mortality. An analysis of the risk factors for predicting difficult RLLR showed that a history of open liver resection was an independent risk factor for difficulty in the Pringle maneuver phase. CONCLUSION: We present a feasible and safe approach to address RLLR difficulty, especially difficulty with the Pringle maneuver using an LSVC, which is extremely useful in RLLR. The Pringle maneuver is more challenging in patients with a history of open liver resection.

Thrombectomized autologous portal Y-graft inflow construction can be an option in living-donor liver transplantation: a case report.

BACKGROUND: In living-donor liver transplantation (LDLT), portal Y-graft interposition using the recipient's portal vein (PV) bifurcation has been used for right lobe grafts with double PV orifices. We herein report the use of thrombectomized autologous portal Y-graft interposition for a recipient with preoperative portal vein thrombosis (PVT) in a right lobe LDLT with double PV orifices. CASE PRESENTATION: The recipient was a 54-year-old male with end-stage liver disease due to alcoholic liver cirrhosis. There was PV thrombus in the recipient's PV. The living liver donor was his 53-year-old spouse, and a right lobe graft was planned for the transplantation. Since the donor's liver had a type III PV anomaly, autologous portal Y-graft interposition after thrombectomy was planned for PV reconstruction in the LDLT. The portal Y-graft was resected from the recipient and a thrombus extending from the main PV to the right PV branch was removed on the back table. The portal Y-graft was anastomosed to the anterior and posterior portal branches of the right lobe graft. Followed by venous reconstruction, the Y-graft was anastomosed to the recipient's main PV. The operation time was 545 min and the intraoperative blood loss was 1355 ml. The recipient was discharged on postoperative day 13 without any complications. The recipient remains well with the patency of the portal Y-graft one year after the liver transplantation. CONCLUSION: We herein report the successful use of autologous portal Y-graft interposition after thrombectomy on the back table for a recipient with PVT in a right lobe LDLT.

Increased incidence of positive peritoneal lavage cytology early after fine needle aspiration in patients with pancreatic ducal adenocarcinoma.

BACKGROUND: The influence of fine needle aspiration (FNA) on peritoneal lavage cytology (CY) in pancreatic ductal adenocarcinoma (PDAC) is unknown. METHODS: We retrospectively analyzed 29 patients with resectable left-sided PDAC undergoing FNA prior to CY examination. We assessed clinical factors related to CY+, scored the tumor diameter (<20 mm = 0, ≥20 mm = 1) and examination interval between FNA and CY (>18 days = 0, ≤18 days = 1), and investigated the probability of CY + by the sum of each score (0-2). RESULTS: The probability of CY+ was 31%. The CY + group had larger tumors and shorter examination intervals than the CY- group. The CY + probability was 75%, 15%, and 13% for a score of 2, 1, and 0, respectively (P = 0.011). CONCLUSION: A short interval between FNA and CY examination for a large tumor may be a risk factor for CY+ in patients with left-sided PDAC.

Blood loss in laparoscopic distal pancreatectomy could be underestimated.

BACKGROUND: Previous studies have reported that laparoscopic distal pancreatectomy (LDP) has an advantage in reducing blood loss over open distal pancreatectomy (ODP). This study was performed to investigate whether blood loss is truly reduced in LDP. METHODS: A total of 113 patients undergoing DP from 2014 to 2022 were classified into Open and LDP groups and compared by statistical analysis. Estimated blood loss (EBL) was calculated from the perioperative changes in the hematocrit, hemoglobin, or red blood cell volume, and actual blood loss (ABL) was taken from the operative record. RESULTS: ABL was significantly lower in the LDP than ODP group (50[5-1350] vs 335 [5-1950] ml, P < .01). However, there were no significant differences in EBL calculated from the hematocrit (406 [66-1990] vs 540 [23-1490] ml, P = .14), hemoglobin, or red blood cell volume. EBL showed more linear correlations with ABL in the ODP group (r = 0.64-0.73) than in the LDP group (r = 0.52-0.57). In the multivariate analysis for ABL, ODP (P = .02) and operative time (P < .01) were significant factors. In contrast, no significant factors were found for EBL. CONCLUSIONS: Intraoperative blood loss may be underestimated in LDP, and a new evaluation method needs to be established.

Sustained Systemic Inflammatory Response Predicts Survival in Patients with Hepatocellular Carcinoma After Hepatic Resection.

BACKGROUND: Preoperative systematic inflammatory response, represented by neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), lymphocyte-monocyte ratio (LMR), and C-reactive protein-albumin ratio (CAR), has been associated with long-term outcomes in patients with hepatocellular carcinoma (HCC). However, the impact of sustained systematic inflammatory response after resection remains unclear. METHODS: This study comprised 210 patients who had undergone primary hepatic resection for HCC between 2008 and 2018. Preoperative and postoperative NLR, LMR, and CAR were evaluated, and patients were then classified into three groups according to the status of each marker: persistently high inflammatory state (elevated group), preoperatively low inflammatory state (normal group), and preoperatively high but postoperatively low inflammatory state (normalized group). Multivariate Cox proportional hazard models were conducted to assess disease-free and overall survival, adjusting for potential confounders. RESULTS: In multivariate analysis, sex (p = 0.002), hepatitis B surface antigen (HBsAg) positivity (p = 0.002), serum α-fetoprotein (AFP) level ≥ 20 ng/mL (p < 0.001), multiple tumors (p < 0.001), microvascular invasion (p = 0.003), type of resection (p = 0.007), and elevated CAR (hazard ratio [HR] 2.40, 95% confidence interval [CI] 1.55-3.73; p < 0.001) were independent and significant predictors of cancer recurrence, while sex (p = 0.05), HBsAg positivity (p = 0.03), serum AFP level ≥20 ng/mL (p = 0.009), multiple tumors (p = 0.03), microvascular invasion (p = 0.006), and elevated CAR (HR 2.10, 95% CI 1.13-3.91; p = 0.02) were independent predictors of overall survival. CONCLUSIONS: Sustained elevated CAR may be an independent and significant indicator of poor long-term outcomes in patients with HCC after hepatic resection, suggesting the interplay of the host's inflammatory state and tumor recurrence and progression in HCC.

Clinical significance of cachexia index in patients with hepatocellular carcinoma after hepatic resection.

BACKGROUND: Cancer cachexia has been associated with unfavorable outcomes in several malignancies. The cachexia index (CXI), which consists of skeletal muscle, inflammation, and nutritional status, has been proposed as a novel biomarker of cachexia. Therefore, we here investigated prognostic value of the CXI in patients with hepatocellular carcinoma (HCC) after hepatic resection. METHODS: The study comprised 213 patients who had undergone primary hepatic resection for HCC between 2008 and 2018. First, the skeletal muscle index (SMI) was calculated as the area of the psoas muscle at the third lumbar vertebra/(the height)2. The CXI was then calculated by the following formula: SMI x serum albumin level/neutrophil-to-lymphocyte ratio (NLR). We retrospectively investigated the relationship between the CXI and disease-free survival as well as overall survival. RESULTS: In multivariate analyses, female (p < 0.01), hepatitis B surface antigen-positivity (p < 0.01), preoperative serum alpha-fetoprotein level ≥20 ng/mL (p = 0.01), preoperative serum protein induced by vitamin K absence or antagonist-II level ≥200 mAU/mL (p = 0.02), multiple tumors (p < 0.01), macrovascular invasion (p = 0.04), type of resection (p < 0.01), and low CXI (p = 0.03) were significant predictors of disease-free survival, while Child-Pugh grade B (p < 0.01), poor tumor differentiation (p = 0.05), multiple tumors (p = 0.01), macrovascular invasion (p = 0.04), NLR (p = 0.04), and low CXI (p < 0.01) were significant predictors of overall survival. In the subgroup analysis of advanced T stage, the CXI was associated with both disease-free (p < 0.01) and overall survival (p = 0.06). CONCLUSIONS: The CXI can be a prognostic indicator in patients with HCC after hepatic resection, suggesting the importance of comprehensive biomarker which includes skeletal muscle, inflammation, and nutritional status.

Preoperative cachexia index can predict the prognosis of extrahepatic biliary tract cancer after resection.

INTRODUCTION: Cachexia is associated with poor survival of patients with bile duct cancer. The cachexia index (CXI), which comprises skeletal muscle, inflammation, and nutritional status, has been proposed as a novel biomarker of cancer cachexia. In this study, we investigated the prognostic significance of the cachexia index after surgical resection of extrahepatic biliary tract cancer. METHODS: Between January 2008 and December 2020, 124 patients underwent radical resection of extrahepatic biliary tract cancer. The skeletal muscle index (SMI) was calculated as the area of the psoas muscle at the third lumbar vertebra/(height)2. CXI was calculated using as: SMI × serum albumin level/neutrophil-to-lymphocyte ratio. We performed univariate and multivariate analyses of the relationships between clinicopathological variables and disease-free and overall survival. RESULTS: The CXI-low group included 57 patients. CXI-low was associated with poor disease-free (p < 0.01) and overall survival (p < 0.01) after curative resection. Preoperative bile duct drainage (p = 0.01), poor tumor differentiation (p = 0.04), advanced Tumor-Nodes-Metastasis (TNM) stage (II or III) (p < 0.01), and CXI-low (p = 0.03) were independent and significant predictors of disease-free survival. Age > 70 years (p = 0.03), preoperative bile duct drainage (p < 0.01), poor tumor differentiation (p = 0.01), advanced TNM stage (II or III) (p = 0.03), and CXI-low (p = 0.04) were independent and significant predictors of overall survival. CONCLUSION: In extrahepatic biliary tract cancer, preoperative CXI-low was an independent and significant risk factor for recurrence and poor prognosis, suggesting that cancer cachexia may progress to tumor development and recurrence.

Standardized and Feasible Laparoscopic Approach for Tumors Located in the Caudate Lobe.

BACKGROUND/AIM: Although laparoscopic hepatectomy has been widely used in the management of liver tumors for its reduced invasiveness and magnified view, in the caudate lobe it remains challenging especially for patients with cirrhosis. Thus, this study aimed to evaluate patients undergoing laparoscopic hepatectomy for hepatic tumors in the caudate lobe and establish strategies for performing such procedure. PATIENTS AND METHODS: Laparoscopic hepatectomy in the caudate lobe was performed in nine patients. We performed inflow control to reduce bleeding during hepatic transection and retraction of the left lateral section to the cranial side to obtain a sufficient surgical field using a Nathanson liver retractor. We approached tumors in the Spiegel lobe (SP) from caudal side for segment 1 (S1) partial hepatectomy and from caudal and left side for Spiegel lobectomy, the lower paracaval portion (PC) from caudal side for S1 partial hepatectomy, and the upper PC from caudal and bilateral side for total caudate lobectomy. RESULTS: In 6 cases the tumors were in the SP and in 3 cases in the PC. The types of laparoscopic hepatectomy performed were total caudate lobectomy (n=1), Spiegel lobectomy (n=2), and partial hepatectomy of segment 1 (n=6). All the tumors were curatively resected, and no patient had complications. Operative time for tumors located in the PC was significantly longer than that for tumors located in the SP. Laparoscopic hepatectomy in the caudate lobe was safely performed for five patients with liver cirrhosis. CONCLUSION: Laparoscopic hepatectomy in the caudate lobe may become the standard surgical technique with hepatic inflow control, sufficient surgical field exposure, and appropriate approach.

Living donor liver transplantation for idiopathic portal hypertension with focal nodular hyperplasia.

The patient was a 61-year-old woman with a history of diabetes mellitus who had undergone ileocecal resection for ascending colon carcinoma 5 years earlier, followed by a postoperative adjuvant chemotherapy with XELOX (capecitabine + oxaliplatin). During follow-up, the liver gradually atrophied, and radiological imaging showed suspicious findings of 20 × 14 mm hepatocellular carcinoma (HCC) in the right lobe of the liver. The patient also underwent endoscopic variceal ligation for the esophageal varices. She was referred to our hospital for living donor liver transplantation (LDLT) due to decompensated liver cirrhosis with HCC. The patient did not have hepatitis B or C, and history of alcohol, suggesting that her liver cirrhosis was caused by a non-alcoholic steatohepatitis. The Child-Pugh score was 10 points (class C) and the Model for End-Stage Liver Disease (MELD) score was 8 points. The possibility of HCC could not be ruled out, and LDLT was performed. Postoperative pathological examination revealed idiopathic portal hypertension (IPH), and the mass lesion was diagnosed as focal nodular hyperplasia (FNH). The postoperative course was uneventful and the patient was discharged on postoperative day 14. This is the first case of liver transplantation for IPH with FNH.

Triple liver hanging maneuver for hepatic central bisectionectomy with caudate lobectomy for resection of huge hepatocellular carcinoma (with video).

Resection of huge hepatocellular carcinomas occupying the central portion of the liver is challenging. Exposure of an adequate liver transection plane using an anterior approach is likely to be difficult because of compression by the tumor. We herein propose a "triple liver hanging maneuver" technique for central bisectionectomy with caudate lobectomy for huge hepatocellular carcinomas stretching the hilar plate and the right and left hepatic veins. In this technique, the first tape is introduced for the transection plane along the right side of the umbilical portion to the anterior surface of the inferior vena cava. The second tape is introduced to lift the paracaval caudate Glissonean pedicles from the hilar plate. The third tape is introduced for the transection plane along the right hepatic vein to the anterior surface of the inferior vena cava. The triple liver hanging maneuver could be effective for huge tumors compressing major hepatic vessels.
