- Abstract
Background: Preoperative recognition of the anatomy of caudate biliary branches is important for the safe and complete resection of perihilar cholangiocarcinoma (PHC). In the present study, we identified these branches using an endoscopic nasobiliary drainage tube (ENBD)., Methods: Between January 2012 and October 2022, 89 patients with suspected PHC underwent computed tomographic (CT) cholangiography through ENBD and caudate biliary branching patterns were examined. Multidetector raw CT (MDCT) scans on 85 patients with PHC without biliary drainage were also investigated. The caudate biliary branches detected by each modality were evaluated., Results: ENBD-CT cholangiography detected 206 caudate branches (2.44 branches/patient), while MDCT identified 62 branches (0.78 branches/patient). ENBD-CT cholangiography showed that 89 caudate branches drained into the left hepatic duct (LHD), 87 into the posterior hepatic duct (Bpost), and 30 into the right hepatic duct. LHD and Bpost were the common roots of the caudate branches. Some branches (20%) joined the contralateral hepatic duct across the left-right border, but not the anterior hepatic duct or infraportal-type Bpost., Conclusions: ENBD-CT cholangiography clearly showed the caudate biliary branches in patients with PHC after biliary drainage., (© 2024 Japanese Society of Hepato‐Biliary‐Pancreatic Surgery.)

- Abstract
Background: Systemic inflammation and altered metabolism are essential hallmarks of cancer. We hypothesized that the rapid turnover protein transthyretin (TTR) (half-life: 2-3 days), compared with the conventional marker albumin (21 days), better reflects the inflammatory/metabolic dynamics of pancreatic ductal adenocarcinoma (PDAC) after neoadjuvant therapy (NAT) and is a useful prognostic marker., Methods: Serum TTR and albumin levels were measured in 104 consecutive post-NAT PDAC patients before curative resection. The associations of preoperative TTR and albumin levels with overall survival (OS) after pancreatectomy were retrospectively analyzed., Results: The mean (SD) TTR and albumin levels were 21.6 (6.4) mg/dL (normal range: ≥22.0 mg/dL) and 3.9 (0.55) g/dL. A low (<22.0 mg/dL) post-NAT TTR level was associated with an advanced tumor stage and higher CEA and CRP levels. Patients with low TTR levels showed significantly worse OS compared with normal levels (3-year OS 39 % vs. 54 %, P = 0.037), although albumin levels did not. We modified prognostic biomarkers of systemic inflammation/metabolism, such as GPS, PNI, and CONUT scores, using the serum TTR instead of albumin level and successfully showed that modified scores were better associated with OS compared with original scores using serum albumin level., Conclusions: Our data suggest that the TTR level is a promising prognostic biomarker for PDAC patients after NAT., Competing Interests: Declaration of competing interest The authors have no conflicts of interest to disclose., (Copyright © 2024.

- Abstract
Purpose: The technical difficulties of laparoscopic liver resection (LLR) are greatly associated with the location of liver tumors. Since segment 8 (S8) contains a wide area, the difficulty of LLR for S8 tumors may vary depending on the location within the segment, such as the ventral (S8v) and dorsal (S8d) area, but the difference is unclear., Methods: We retrospectively investigated 30 patients who underwent primary laparoscopic partial liver resection for liver tumors in S8 at Kobe University Hospital between January 2018 and June 2023., Results: Thirteen and 17 patients underwent LLR for S8v and S8d, respectively. The operation time was significantly longer (S8v 203[135-259] vs. S8d 261[186-415] min, P = 0.002) and the amount of blood loss was significantly higher (10[10-150] vs. 10[10-200] mL, P = 0.034) in the S8d group than in the S8v group. No significant differences were observed in postoperative complications or postoperative length of hospital stay. Additionally, intraoperative findings revealed that the rate at which the case performed partial liver mobilization in the S8d group was higher (2[15.4%] vs. 8[47.1%], P = 0.060) and the median parenchymal transection time of the S8d group was longer (102[27-148] vs. 129[37-175] min, P = 0.097) than those in the S8v group, but there were no significant differences., Conclusion: The safety of LLR for the S8d was comparable to that of LLR for S8v, although LLR for S8d resulted in longer operative time and more blood loss., The Trial Registration Number: B230165 (approved at December 26, 2023)., (© 2024.

- Abstract
Purpose: The impact of postoperative bile leak on the prognosis of patients with hepatocellular carcinoma who underwent liver resection is controversial. This study aimed to investigate the prognostic impact of bile leak for patients with hepatocellular carcinoma who underwent liver resection., Methods: Patients with hepatocellular carcinoma who underwent liver resection between 2009 and 2019 at Kobe University Hospital and Hyogo Cancer Center were included. After propensity score matching between the bile leak and no bile leak groups, differences in 5-year recurrence-free and overall survival rates were evaluated using the Kaplan-Meier method., Results: A total of 781 patients, including 43 with postoperative bile leak, were analyzed. In the matched cohort, 40 patients were included in each group. The 5-year recurrence-free survival rates after liver resection were 35% and 32% for the bile leak and no bile leak groups, respectively (P = 0.857). The 5-year overall survival rates were 44% and 54% for the bile leak and no bile leak groups, respectively (P = 0.216)., Conclusion: Overall, bile leak may not have a profound negative impact on the prognosis of patients with hepatocellular carcinoma who have undergone liver resection., (© 2024.

- Abstract
Novel adhesives for biological tissues offer an advanced surgical approach. Here, the authors report the development and application of solid-state adhesives consisting of porous hydroxyapatite (HAp) biocompatible ceramics as novel internal organ retractors. The operational principles of the porous solid-state adhesives are experimentally established in terms of water migration from biological soft tissues into the pores of the adhesives, and their performance is evaluated on several soft tissues with different hydration states. As an example of practical medical utility, HAp adhesive devices demonstrate the holding ability of porcine livers and on-demand detachability in vivo, showing great potential as internal organ retractors in laparoscopic surgery., (© 2024 The Authors.

- Abstract
Introduction: Surgical resection is considered an effective cure for biliary tract cancer (BTC); however, the prognosis is unsatisfactory despite improved surgical techniques and perioperative management. The recurrence rate remains high even after curative resection. The efficacy of adjuvant chemotherapy in pancreatic and gastric cancers has been previously reported, and the feasibility of adjuvant therapy with S-1 has recently been reported in patients with resected BTC. We aimed to retrospectively investigate the effects of adjuvant chemotherapy with S-1 on resected advanced BTC., Methods: We included data from 438 BTC patients who underwent resection between 2001 and 2020. After excluding patients with pTis-pT1 (n = 112) and other exclusion criteria, 266 patients were included in the analysis., Results: After propensity score matching, 48 patients received S-1 adjuvant chemotherapy (S-1 group), and 48 patients received non-S1 adjuvant chemotherapy or underwent surgery alone (Non-S-1 group). The patients in the S-1 group had significantly better overall survival (OS) than those in the non-S-1 group (MST 51 vs 37 months, hazard ratio [HR]:.54, 95% confidence interval [CI]:.30-.98, P = .04). The S-1 group had a significantly better recurrence-free survival (RFS) than the non-S-1 group (94 vs 21 months, HR: .57, 95% CI: .33-.97, P = .03). Subgroup analyses for OS and RFS exhibited the benefits of S-1 in patients aged <75 years and in patients with primary sites of extrahepatic and perineural invasion and curability of R0., Discussion: S-1 adjuvant therapy is promising for improving the postoperative survival of patients with resected advanced BTC, positive nerve invasion, and R0 resection., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Background/aim: This study aimed to evaluate the utility of the albumin-bilirubin grade for predicting the prognosis after repeat liver resection for patients with recurrent hepatocellular carcinoma., Patients and Methods: Ninety patients with intrahepatic recurrent hepatocellular carcinoma who underwent repeat liver resection at our institution between 2005 and 2019 were retrospectively analyzed. Cox proportional-hazards regression models evaluated independent preoperative prognostic factors, including the albumin-bilirubin grade. Prognosis differences between patients with albumin-bilirubin grades 1 and 2 were analyzed using the Kaplan-Meier method., Results: Cox proportional-hazards regression analysis revealed that albumin-bilirubin grade 2 (p=0.003) and early recurrence within one year from the initial surgery (p=0.001) were independently associated with poor recurrence-free survival, and albumin-bilirubin grade 2 (p=0.020) was independently associated with poor overall survival. The five-year recurrence-free (31% and 17%, respectively) and overall (86% and 60%, respectively) survival rates after repeat liver resection for patients with albumin-bilirubin grades 1 and 2 were significantly different between groups (both p=0.003)., Conclusion: The albumin-bilirubin grade is useful for preoperatively predicting favorable survival rates after repeat liver resection for patients with recurrent hepatocellular carcinoma. Patients with an albumin-bilirubin grade 1 are better candidates for surgical treatment of recurrent hepatocellular carcinoma., (Copyright © 2024 International Institute of Anticancer Research (Dr. George J.

- Abstract
Background: Drainage fluid amylase (DFA) is useful for predicting clinically relevant postoperative pancreatic fistula (CR-POPF) after distal pancreatectomy (DP). However, difference in optimal cutoff value of DFA for predicting CR-POPF between open DP (ODP) and laparoscopic DP (LDP) has not been investigated. This study aimed to identify the optimal cutoff values of DFA for predicting CR-POPF after ODP and LDP., Methods: Data for 294 patients (ODP, n = 127; LDP, n = 167) undergoing DP at Kobe University Hospital between 2010 and 2021 were reviewed. Propensity score matching was performed to minimize treatment selection bias. Receiver operating characteristic (ROC) analysis was performed to determine the optimal cutoff values of DFA for predicting CR-POPF for ODP and LDP. Logistic regression analysis for CR-POPF was performed to investigate the diagnostic value of DFA on postoperative day (POD) three with identified cutoff value., Results: In the matched cohort, CR-POPF rates were 24.7% and 7.9% after ODP and LDP, respectively. DFA on POD one was significantly lower after ODP than after LDP (2263 U/L vs 4243 U/L, p < 0.001), while the difference was not significant on POD three (543 U/L vs 1221 U/L, p = 0.171). ROC analysis revealed that the optimal cutoff value of DFA on POD one and three for predicting CR-POPF were different between ODP and LDP (ODP, 3697 U/L on POD one, 1114 U/L on POD three; LDP, 10564 U/L on POD one, 6020 U/L on POD three). Multivariate analysis showed that DFA on POD three with identified cutoff value was the independent predictor for CR-POPF both for ODP and LDP., Conclusions: DFA on POD three is an independent predictor for CR-POPF after both ODP and LDP. However, the optimal cutoff value for it is significantly higher after LDP than after ODP. Optimal threshold of DFA for drain removal may be different between ODP and LDP., (© 2024.

- Abstract
Intrahepatic cholangiocarcinoma (iCCA) has been subclassified by its gross morphology into the mass-forming (MF), periductal-infiltrating (PI), and intraductal growth (IG) types and their combinations. This classification correlates well with clinical features; for example, MF-iCCA has less lymph-node metastasis and a better prognosis than PI-iCCA. According to the recently accumulated evidence from histological investigations, the WHO classification endorsed a subclassification scheme in which iCCA cases are classified into small- and large-duct types. Small-duct iCCA is considered to originate from septal or smaller bile ducts and is characterized by less frequent lymph-node metastasis, a favorable prognosis, and an MF appearance. Large-duct iCCA arises around the second branch of the biliary tree and has more aggressive biology and distinct genetic abnormalities. According to the practice guidelines for iCCA from the Liver Cancer Study Group of Japan and the National Comprehensive Cancer Network, upfront surgery is recommended for iCCA without distant metastasis regardless of the morphological subtype, based on clinical experience. In consideration of the biological heterogeneity of iCCA, the treatment strategy for iCCA needs to be reconsidered based on the WHO subtypes., (© 2024.

- Abstract
Background: Venous thromboembolism (VTE) is a potentially fatal complication of hepatectomy. The use of postoperative prophylactic anticoagulation in patients who have undergone hepatectomy is controversial because of the risk of postoperative bleeding. Therefore, we hypothesized that monitoring plasma D-dimer could be useful in the early diagnosis of VTE after hepatectomy., Aim: To evaluate the utility of monitoring plasma D-dimer levels in the early diagnosis of VTE after hepatectomy., Methods: The medical records of patients who underwent hepatectomy at our institution between January 2017 and December 2020 were retrospectively analyzed. Patients were divided into two groups according to whether or not they developed VTE after hepatectomy, as diagnosed by contrast-enhanced computed tomography and/or ultrasonography of the lower extremities. Clinicopathological factors, including demographic data and perioperative D-dimer values, were compared between the two groups. Receiver operating characteristic curve analysis was performed to determine the D-dimer cutoff value. Univariate and multivariate analyses were performed using logistic regression analysis to identify significant predictors., Results: In total, 234 patients who underwent hepatectomy were, of whom (5.6%) were diagnosed with VTE following hepatectomy. A comparison between the two groups showed significant differences in operative time (529 vs 403 min, P = 0.0274) and blood loss (530 vs 138 mL, P = 0.0067). The D-dimer levels on postoperative days (POD) 1, 3, 5, 7 were significantly higher in the VTE group than in the non-VTE group. In the multivariate analysis, intraoperative blood loss of > 275 mL [odds ratio (OR) = 5.32, 95% confidence interval (CI): 1.05-27.0, P = 0.044] and plasma D-dimer levels on POD 5 ≥ 21 μg/mL (OR = 10.1, 95%CI: 2.04-50.1, P = 0.0046) were independent risk factors for VTE after hepatectomy., Conclusion: Monitoring of plasma D-dimer levels after hepatectomy is useful for early diagnosis of VTE and may avoid routine prophylactic anticoagulation in the postoperative period., Competing Interests: Conflict-of-interest statement: All the authors report no relevant conflicts of interest for this article., (©The Author(s) 2024.

- Abstract
A 72-year-old male patient presented with obstructive jaundice and was diagnosed with ampullary carcinoma. Contrast- enhanced computed tomography(CT)showed stenosis of the common hepatic artery and dilatation of the pancreaticoduodenal arcade(PDA)due to celiac axis stenosis(CAS)at the origin, suggesting that hepatic artery blood flow was supplied from the superior mesenteric artery via the PDA. Since calcification of the arterial wall was observed at the origin of the celiac artery(CA), the cause of the CAS was diagnosed as atherosclerotic. An intraoperative gastroduodenal artery(GDA) clamp test showed no obvious decrease in hepatic arterial blood flow. However, because of concerns about the postoperative patency of the CA, an inferior pancreaticoduodenal artery-GDA bypass using the left great saphenous vein and subtotal stomach-preserving pancreaticoduodenectomy were performed. The postoperative course was uneventful. When pancreaticoduodenectomy is performed in patients with atherosclerotic CAS, this arterial reconstruction method can be considered as an option.

- Abstract
Transarterial chemoembolization (TACE) is performed for pancreatic neuroendocrine tumor (PanNEN) liver metastases; however, the safety and efficacy of TACE procedures, especially for patients who have undergone previous pancreatic surgery, have not been established. We reviewed 48 TACE procedures (1-6 procedures/patient) performed on 11 patients with PanNEN liver metastases, including 16 TACE procedures (4-6 procedures/patient) for 3 patients with a history of biliary-enteric anastomosis. The overall tumor objective response rate was 94%. The incidence of Clavien‒Dindo grade ≥ 2 complications was 1/16 (6%) and 1/32 (3%), and the median time to untreatable progression was 31 (14-41) and 27 (2-60) months among patients with and without a history of biliary-enteric anastomosis, respectively. Although validation is needed in future studies, our experiences have shown that TACE treatment is a viable treatment option for PanNEN liver metastases, even after biliary-enteric anastomosis with experienced teams and careful patient follow-up., (© 2023.

- Abstract
Introduction: With the aging of the population in Japan, gallbladder cancer (GBC) in the elderly is increasing. However, the available clinical data are limited, and the optimal treatment is still controversial. The aim of this study was to evaluate the benefit of surgical resection in GBC patients ≥75 years of age., Methods: A retrospective single center analysis of patients who had undergone surgical resection for GBC between 2000 and 2019 was carried out. Patients aged ≥75 years (elderly group, n = 24) or <75 years (younger group, n = 50) were compared., Results: Both younger and elderly patients exhibited similar clinicopathological characteristics, but comorbidity in the latter was significantly greater, as was the frequency of less invasive surgery. Nonetheless, the incidence of postoperative complications was similar in elderly and younger patients. The proportion of patients receiving adjuvant chemotherapy was lower in the elderly. Overall survival of elderly and younger patients was not significantly different (65.0 vs 62.4% at 5 years, P = .600). In multivariate analysis, residual tumor status but not age was an independent prognostic factor., Discussion: This study demonstrated that appropriate surgical treatment of elderly GBC patients was safe and effective, despite their having more comorbidities and lower rates of adjuvant chemotherapy than younger patients., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Background: The safety and efficacy of laparoscopic liver resection (LLR) have been reported worldwide. However, those of LLR for tumors located in Couinaud's segment 8 are not sufficiently investigated., Methods: We retrospectively analyzed 108 patients who underwent liver resection for hepatocellular carcinoma (HCC) in segment 8 at Kobe University Hospital and Hyogo Cancer Center between January 2010 and December 2021. The patients were categorized in LLR and open liver resection (OLR) groups, and 1:1 propensity score matching (PSM) was performed to compare surgical outcomes between the groups., Results: Forty-seven and 61 patients underwent LLR and OLR, respectively. After PSM, each group contained 34 patients. There was no significant difference in operation time between the groups (331 min vs. 330 min, P = 0.844). Patients in the LLR group had significantly less blood loss (30 mL vs. 468 mL, P < 0.001) and shorter length of postoperative hospital stay (10 days vs. 12 days, P = 0.015) than those in the OLR group. There was no significant difference in the occurrence of postoperative complications between the groups (12% vs. 9%, P = 0.690). Further, the 1-year cumulative incidence of recurrence was not significantly different between the groups (16% vs. 19%, P = 0.734)., Conclusions: The surgical outcomes and short-term prognosis of LLR were similar or better than those of OLR. LLR could be an effective and safe procedure, even for lesions located in segment 8, which is considered a difficult anatomical location for LLR., (© 2023.

- Abstract
Background: Postoperative cholangitis is a common complication of pancreaticoduodenectomy. Frequent cholangitis impairs patients' quality of life after pancreaticoduodenectomy. However, the risk factors for recurrence of cholangitis remain unclear. Hence, this retrospective study aimed to identify risk factors for recurrence of cholangitis after pancreaticoduodenectomy., Methods: The medical records of patients who underwent pancreaticoduodenectomy between 2015 and 2019 in our institution were retrospectively reviewed. At least two episodes of cholangitis a year after pancreaticoduodenectomy were defined as 'recurrence of cholangitis' in the present study. Univariate and multivariate analyses were performed., Results: The recurrence of cholangitis occurred in 40 of 207 patients (19.3%). Multivariate analysis revealed that internal stent (external, RR: 2.16, P = 0.026; none, RR: 4.76, P = 0.011), firm pancreas (RR: 2.61, P = 0.021), constipation (RR: 3.49, P = 0.008), and postoperative total bilirubin>1.7 mg/dL (RR: 2.94, P = 0.006) were risk factors of recurrence of cholangitis. Among patients with internal stents (n = 54), those with remnant stents beyond 5 months had more frequent recurrence of cholangitis (≥5 months, 75%; <5 months, 30%)., Conclusions: Internal stents, firm pancreas, constipation, and postoperative high bilirubin levels are risk factors for cholangitis recurrence after pancreaticoduodenectomy. In addition, the long-term implantation of internal stents may trigger cholangitis recurrence., (© 2023. The Author(s) under exclusive licence to Société Internationale de Chirurgie.)

- Abstract
Background: The exfoliative cell analyzer, LC-1000, is medical device that utilizes the principles of flow cytometry, and might provide digital diagnostic information for cytology using a different approach from conventional cytomorphology. In this study, wae examined the usefulness of the LC-1000 as a diagnostic support system for intraoperative peritoneal lavage cytology and its prognostic impact for pancreatic (PC) and biliary tract cancer (BTC)., Methods: Patients with PC and BTC who underwent surgical treatment were included. First, we identified useful indicators of LC-1000 and established cutoff values to discriminate positive cytology. Next, we verified the validity of these cutoff values., Results: In the test set (n = 48), of the LC-1000 indicators examined, only MR-CPIx was significantly different between the negative and positive cytology groups, yielding a cutoff value of 0.86. In the validation set (n = 52), the sensitivity, specificity, positive and negative predictive value of the LC-1000 for cytology results was 1.0, 0.49, 0.11 and 1.0, respectively. In patients who had undergone radical resection, recurrence-free survival rate was significantly higher in the LC-1000 negative group than in the positive group in PC, but not in BTC., Conclusion: The LC-1000 was useful as digital support system for peritoneal cytology, and it might have potential as a prognostic factor for PC., (© 2023 Japanese Society of Hepato-Biliary-Pancreatic Surgery.)

- Abstract
Background: Less intra-abdominal adhesions are expected following laparoscopic surgery. Although an initial laparoscopic approach for primary liver tumors may have advantages in patients who require repeat hepatectomies for recurrent liver tumors, this has not been sufficiently investigated., Methods: Patients who underwent repeat hepatectomies for recurrent liver tumors at our hospital between 2010 and 2022 were retrospectively analyzed. Of 127 patients, 76 underwent laparoscopic repeat hepatectomy (LRH), of whom 34 patients initially underwent laparoscopic hepatectomy (L-LRH) and 42, open hepatectomy (O-LRH). Fifty-one patients underwent open hepatectomy as both the initial and second operation (O-ORH). We analyzed surgical outcomes between L-LRH and O-LRH groups and between L-LRH and O-ORH groups using propensity-matching analysis for each pattern., Results: Twenty-one patients each were included in L-LRH and O-LRH propensity-matched cohorts. The L-LRH group had a lower rate of postoperative complications than the O-LRH group (0 vs 19%, P = 0.036). When we compared surgical outcomes between L-LRH and O-ORH groups in another matched cohort with 18 patients in each group, in addition to the lower rate of postoperative complications, the L-LRH group had additional favorable surgical outcomes including shorter operation time and lower blood loss volume than the O-ORH group (291 vs 368 min, P = 0.037 and 10 vs 485 mL, P < 0.0001)., Conclusions: An initial laparoscopic approach would be favorable for patients undergoing repeat hepatectomies, as it leads to lower risk of postoperative complications. Compared with O-ORH, the advantage of the laparoscopic approach may be enhanced when it is repeatedly adopted., (© 2023. The Society for Surgery of the Alimentary Tract.)

- Abstract
Background: Intracholecystic papillary neoplasm (ICPN) is one of the precursors of gallbladder cancer defined in the 2010 World Health Organization classification of tumors. We herein report ICPN with pancreaticobiliary maljunction (PBM), which is a high-risk factor for biliary cancer., Case Presentation: A 57-year-old female presented with abdominal pain. Computed tomography showed a swollen appendix and gallbladder nodules with bile duct dilatation. Endoscopic ultrasonography revealed a gallbladder tumor spreading into the cystic duct confluence accompanying PBM. Based on papillary tumors around the cystic duct detected using the SpyGlass DS II Direct Visualization System (SpyGlass DS), ICPN was suspected. We performed extended cholecystectomy, extrahepatic bile duct resection, and appendectomy with a diagnosis of ICPN and PBM. The pathological diagnosis was ICPN (90 × 50 mm) with high-grade dysplasia spreading into the common bile duct. The absence of residual cancer in the resected specimen was pathologically confirmed. P53 staining was totally negative in both the tumor and normal epithelium. The overexpression of CTNNB1 was not observed., Conclusions: We encountered a patient with a very rare gallbladder tumor, ICPN with PBM. SpyGlass DS contributed to a precise assessment of the extent of the tumor as well as a qualitative diagnosis., (© 2023. Japanese Society of Gastroenterology.)

- Abstract
Background: Post-transplantation weight control is important for long-term outcomes; however, few reports have examined postoperative weight change. This study aimed to identify perioperative factors contributing to post-transplantation weight change., Methods: Twenty-nine patients who underwent liver transplantation between 2015 and 2019 with an overall survival of >3 years were analyzed., Results: The median age, model for end-stage liver disease score, and preoperative body mass index (BMI) of the recipients were 57, 25, and 23.7, respectively. Although all but one recipient lost weight, the percentage of recipients who gained weight increased to 55% (1 month), 72% (6 months), and 83% (12 months). Among perioperative factors, recipient age ≤50 years and BMI ≤25 were identified as risk factors for weight gain within 12 months (P < .05), and patients with age ≤50 years or BMI ≤25 recipients gained weight more rapidly (P < .05). The recovery time of serum albumin level ≥4.0 mg/dL was not statistically different between the 2 groups. The weight change during the first 3 years after discharge was represented by an approximately straight line, with 18 and 11 recipients showing a positive and negative slope, respectively. Body mass index ≤23 was identified as a risk factor for a positive slope of weight gain (P <.05)., Conclusions: Although postoperative weight gain implies recovery after transplantation, recipients with a lower preoperative BMI should strictly manage body weight as they may be at higher risk of rapid weight increase., (Copyright © 2023 Elsevier Inc.

- Abstract
Background/aim: Recently, the Global Leadership Initiative on Malnutrition (GLIM), which includes the world's leading clinical nutrition societies, proposed the first global diagnostic criteria for malnutrition. However, the association between malnutrition diagnosed by the GLIM criteria and prognosis in patients with resected extrahepatic cholangiocarcinoma (ECC) remains unknown. This study aimed to investigate the predictive validity of the GLIM criteria for the prognosis of patients with resected ECC., Patients and Methods: Between 2000 and 2020, 166 patients who underwent curative-intent resection for ECC were retrospectively analyzed. Prognostic significance of preoperative malnutrition diagnosed by the GLIM criteria was investigated using a multivariate Cox proportional hazards model., Results: Eighty-five (51.2%) and 46 (27.7%) patients were diagnosed with moderate and severe malnutrition, respectively. Increased malnutrition severity tended to be correlated with increased lymph node metastasis rate (p-for-trend=0.0381). The severe malnutrition group had worse 1-, 3-, and 5-year overall survival rates than the normal (without malnutrition) group (82.2% vs. 91.2%, 45.6% vs. 65.1%, 29.3% vs. 61.5%, respectively, p=0.0159). In multivariate analysis, preoperative severe malnutrition was an independent predictor for poor prognosis (hazard ratio=1.68, 95% confidence interval=1.06-2.66, p=0.0282), along with intraoperative blood loss >1,000 ml, lymph node metastasis, perineural invasion, and curability., Conclusion: Severe preoperative malnutrition diagnosed by the GLIM criteria was associated with poor prognosis in patients who underwent curative-intent resection for ECC., (Copyright © 2023 International Institute of Anticancer Research (Dr. George J.

- Abstract
Aim: Sorafenib was previously considered a first-line treatment for hepatocellular carcinoma (HCC) patients with macroscopic portal vein tumor thrombus (PVTT). This case-matched analysis was performed to evaluate the best first-line treatment for HCC in patients with macroscopic PVTT., Methods: The HCC patients with Vp2 (PVTT invaded into a second-order portal branch), Vp3 (first-order portal branch), and Vp4 (main trunk or contralateral portal vein) PVTT who underwent hepatectomy and those treated with sorafenib were included. Treatment results were compared between the two modalities for each PVTT category, and a propensity analysis was performed for patients with Vp3 and Vp4 (Vp3/4)., Results: The median survival times (MSTs) of patients with Vp2, Vp3, and Vp4 PVTT who underwent hepatectomy were 21.4, 13.6, and 14.9 months, respectively; the MSTs for those with Vp2, Vp3, and Vp4 PVTT who received sorafenib treatment were 6.9, 5.5, and 3.6 months, respectively, with a significant difference. In a propensity-matched cohort of patients with Vp3/4 PVTT (36 patients in each), the MST of patients who underwent hepatectomy (15.1 months) was significantly better than the patients treated with sorafenib (4.5 months)., Conclusion: Hepatectomy can be associated with prolonged survival in HCC patients with macroscopic PVTT., (© 2022 Japanese Society of Hepato-Biliary-Pancreatic Surgery.)

- Abstract
Background: Cold agglutinin disease (CAD) is a rare autoimmune hemolytic anemia characterized by agglutination of red blood cells at temperatures below the normal core body temperature. In patients with CAD, splenectomy is not indicated because of its low therapeutic effect on hemolytic anemia induced by extravascular hemolysis. Herein, we report a case of refractory hemolytic anemia with CAD successfully managed with splenectomy., Clinical Case: A 60-year-old man visited a municipal hospital with the chief complaint of fatigue. He was found to have hemolytic anemia and icterus with increased cold agglutination and was diagnosed with CAD. Malignant lymphoma was suspected as the underlying disease; however, no clear underlying disease was identified. Hemolytic anemia progressed during the subsequent winter seasons, and he was treated with temperature control, warming, and weekly blood transfusions. However, despite the blood transfusions, his hemoglobin level did not improve during the summer 2 years after diagnosis, and his previously observed splenomegaly had progressed. He was referred to our department, and a splenectomy was performed to diagnose any occult malignant lymphoma and improve the refractory hemolytic anemia. Because histopathological examination revealed no evidence of malignant lymphoma, a diagnosis of primary CAD was made. The hemolytic anemia improved, and no blood transfusion was required after splenectomy., Conclusions: Splenectomy significantly improved the patient's refractory hemolytic anemia due to primary CAD. Thus, it may be an effective treatment option in such cases, although further cases and studies are required to evaluate the effects of splenectomy.

- Abstract
Background: Pancreatic ductal adenocarcinoma (PDAC) has a high recurrence rate even after curative resection. Lung recurrence may have better outcomes than other recurrences. However, its detailed clinicopathological features are unclear. We investigated the clinicopathological features and risk factors for lung recurrence after pancreatectomy for PDAC., Methods: The study included 161 patients with potentially and borderline resectable PDAC who had undergone R0 or R1 pancreatectomy between January 2008 and December 2016. We retrospectively examined the prognosis and predictors for lung recurrence after curative resection., Results: Seventeen patients (10.6%) had isolated lung recurrence. The median overall and recurrence-free survivals were 38.0 and 16.1 months, respectively. In multivariate analysis, para-aortic lymph node (PALN) metastasis (p = 0.006) and female sex (p = 0.027) were independent factors for lung recurrence., Conclusion: Lung recurrence had a better prognosis than other recurrences. PALN metastasis and female sex are independent risk factors for lung recurrence after curative resection for PDAC., Competing Interests: Declaration of competing interest The Authors declare no conflicts of interest., (Copyright © 2022 Asian Surgical Association and Taiwan Robotic Surgery Association.

- Abstract
Background: Bile leakage is a major complication after liver transplantation and remains as a significant source of morbidity and mortality. In 2011, the International Study Group of Liver Surgery (ISGLS) defined bile leakage as a drain/serum bilirubin ratio ≥3. However, to our knowledge there is no literature assessing serum and drain bilirubin concentrations after liver transplantation. The aim of this study was to describe the natural postoperative changes in serum and drain fluid bilirubin concentrations in patients after liver transplantation., Methods: We included 32 patients who underwent liver transplantation at Kobe University Hospital from January 2007 to December 2020. We enrolled 34 living donors who had no complications as the control group., Results: The recipient serum total/direct bilirubin concentration were higher compared with the donors from postoperative day (POD) 1 to 5 with a statistical difference (P < .05). The recipient drain/serum total bilirubin ratio was lower than donors on POD 3 (0.89 ± 0.07 vs 1.53 ± 0.07: P < .0001), which was also confirmed by the recipient drain/serum direct bilirubin ratio (0.64 ± 0.10 vs 1.18 ± 0.09: P < .0001). On POD 3, the drain fluid volume (647.38 ± 89.47 vs 113.43 ± 86.8 mL: P < .001) and serum total bilirubin concentration (6.73 ± 0.61 vs 1.23 ± 0.60 mg/dL: P < .001) was higher in the recipients than in donors. Categorized in 2 groups, the higher drain fluid volume and bilirubin concentration recipients showed lower drain/serum total bilirubin ratio compared with the other group (P = .03) CONCLUSION: The drain/serum bilirubin ratio in the transplanted patients could be calculated lower compared with the hepatectomy patients because of high drain fluid volume and hyperbilirubinemia. Great care should be taken when assessing the bile leakage in liver transplant recipients using the ISGLS definition., Competing Interests: DISCLOSURE The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Inc.

- Abstract
Stapling is the standard method for pancreatic transection during laparoscopic distal pancreatectomy. Although most surgeons use a 60 mm cartridge stapler, space limitations created by laparoscopic surgery make the instrument difficult to handle, especially during pancreatic transection at the neck. Therefore, we currently use a 45 mm cartridge stapler for laparoscopic pancreatic transection at the neck. Between October 2019 and December 2020, we performed pancreatic transection using a 45 mm cartridge stapler in 27 patients. Fifteen patients experienced biochemical leakage, but no patients developed clinically relevant pancreatic fistula. The compactness of the 45 mm cartridge has several benefits: (1) less space is required for flexing, opening, and closing the device; (2) it enables easy insertion of the lower jaw behind the pancreas, even if the dissected space behind the pancreas is narrow; (3) less obstruction of the surgeons' view prevents accidental injury to the surrounding tissues and vessels. These benefits may enable safe pancreatic transection., (© 2022. The Author(s) under exclusive licence to Springer Nature Singapore Pte Ltd.)

- Abstract
Background: Laparoscopic caudate lobe resection is a challenging procedure. Several researchers have reported the safety of laparoscopic liver resections;1.Transl Gastroenterol Hepatol. 1:56;2.Asian J Endosc Surg. 12:232-236;3.Ann Surg Oncol. 26:2980; however, a standardized procedure has not yet been established. Herein, we present a video showing laparoscopic Spiegel lobectomy in a patient with 6-cm hepatocellular carcinoma (HCC) using a novel approach., Patient and Methods: A 63-year-old man with a caudate lobe HCC was referred to our hospital. Computed tomography showed a 5 × 6 cm
2 HCC located in the Spiegel lobe, which profoundly displaced the inferior vena cava (IVC) to the lower right side, and mobilization of the Spiegel lobe was considered difficult. To perform the dissection between the Siegel lobe and IVC safely, we performed parenchymal transection along the ventral side of the IVC initially. The Spiegel lobe was then dislocated to the left side of the IVC. We dissected the left lateral side of the IVC, including the proper hepatic vein draining the caudate lobe and the left IVC ligament with a safe operative field, and successfully removed the Spiegel lobe with large HCC., Results: The operation time was 383 min. The blood loss was 10 mL. The patient was discharged on the seventh postoperative day without any complications. Histopathological examination revealed well-differentiated HCC with a negative surgical margin., Conclusions: Laparoscopic medial-to-lateral approach with initial parenchymal transection at the medial side of the Spiegel lobe followed by dissection of the left lateral side of the IVC is considered as a safe and effective procedure for large tumors in the Spiegel lobe., (© 2022.

- Abstract
Background: Anatomic liver resection (ALR) has been established to eliminate the tumor-bearing hepatic region with preservation of the remnant liver volume for liver malignancies. Recently, laparoscopic ALR has been widely applied; however, there are few reports on laparoscopic segmentectomy 2. This study aimed to present the standardization of laparoscopic segmentectomy 2 with surgical outcomes., Methods: This study included seven patients who underwent pure laparoscopic segmentectomy 2 by the Glissonean approach from January 2020 to December 2021. Four of them had hepatocellular carcinoma, two had colorectal liver metastasis, and one had hepatic angiomyolipoma, which was preoperatively diagnosed with hepatocellular carcinoma. In all patients, preoperative three-dimensional (3D) simulation images from dynamic CT were reconstructed using a 3D workstation. The layer between the hepatic parenchyma and the Glissonean pedicle of segment 2 (G2) was dissected to encircle the root of G2. After clamping or ligation of the G2, 2.5 mg of indocyanine green was injected intravenously to identify the boundaries between segments 2 and 3 with a negative staining method under near-infrared light. Parenchymal transection was performed from the caudal side to the cranial side according to the demarcation on the liver surface, and the left hepatic vein was exposed on the cut surface if possible., Results: The mean operative time for all patients was 281 min. The mean blood loss was 37 mL, and no transfusion was necessary. Estimated liver resection volumes significantly correlated with actual liver resection volumes (r = 0.61, P = 0.035). After the operation, one patient presented with asymptomatic deep venous and pulmonary thrombosis, which was treated with anticoagulant therapy. The mean length of hospital stay was 8.9 days., Conclusion: Laparoscopic segmentectomy 2 by the Glissonean approach is a feasible and safe procedure with the preservation of the nontumor-bearing segment 3 for liver tumors in segment 2., (© 2022.

- Abstract
Background: Resecting liver tumors located in Couinaud's segment VII is challenging; the efficacy and safety of laparoscopic liver resection for segment VII lesions compared to open liver resection remain unclear., Methods: Medical records of 84 patients who underwent liver resection of segment VII at Kobe University Hospital and Hyogo Cancer Center between 2010 and 2021 were retrospectively analyzed. Surgical outcomes were compared between laparoscopic liver resection and open liver resection groups using propensity matching analysis., Results: Thirty-one and 53 patients underwent laparoscopic liver resection and open liver resection, respectively. After propensity matching, 29 patients were included in each group. The laparoscopic liver resection group had a significantly longer operation time (407 vs. 305 min, P = 0.002), lower blood loss (100 vs. 230 mL, P = 0.004), and higher postoperative alanine aminotransferase levels (436 vs. 252 IU/L, P = 0.008) than the open liver resection group. In patients with liver cirrhosis, the proportion of patients with postoperative liver-specific complications was higher in the laparoscopic liver resection group than in the open liver resection group (57% vs 11%, P = 0.049), although there was no significant difference in postoperative liver-specific complication rates between the groups in patients without liver cirrhosis., Conclusions: For liver resection of segment VII, laparoscopic liver resection led to higher postoperative liver damage than open liver resection. Open liver resection may be better for patients with liver cirrhosis to avoid postoperative liver-specific complications. Laparoscopic liver resection could be an acceptable procedure for patients without liver cirrhosis, with some merits such as less blood loss., (© 2022.

- Abstract
Portal vein thrombosis (PVT) is a lethal complication of hepatectomy if not properly treated. An 81-year-old woman diagnosed with postoperative PVT after right hepatectomy and caudate lobectomy for perihilar cholangiocarcinoma. Elevation of serum total bilirubin levels, D-dimer levels, and glossy ascites appeared on postoperative day 5 (POD5), and a contrast-enhanced CT confirmed PVT. Thrombi were found from the umbilical portion of the portal vein to the superior mesenteric vein. There were signs of acute liver failure due to thrombi obstructing the portal vein. Therefore, emergent catheter thrombus aspiration was performed under laparotomy. An aspiration catheter was inserted into the superior mesenteric vein from the ileocolic vein. We performed direct aspiration thrombectomy, followed by anticoagulant administration using urokinase via the catheter. Partial recanalization of the portal vein and superior mesenteric vein was observed. To dissolve residual thrombi, edoxaban administration was started on POD6. Contrast-enhanced CT 16 days after her additional operation showed the thrombi had completely disappeared. The patient was discharged on POD76. She had no recurrence of PVT over the next 6 months. Combination therapy of early intervention using aspiration catheter and systemic anticoagulant medication was useful for severe postoperative PVT accompanied with liver failure., (© 2022.

- Abstract
Endoscopic papillectomy for early ampullary tumors is considered a minimally invasive and useful alternative to pancreatoduodenectomy; however, its indications remain unclear. This study aimed to clarify the advantages of endoscopic papillectomy by investigating the clinical outcomes of patients who underwent endoscopic papillectomy or pancreatoduodenectomy for early ampullary tumors. Patients diagnosed with early ampullary tumors (adenoma, Tis, T1a) who underwent endoscopic papillectomy or pancreatoduodenectomy between June 2008 and October 2019 were included, and their clinical outcomes were analyzed. Seventy-four patients (34 patients with adenomas and 40 patients with adenocarcinomas) were divided into two groups, namely endoscopic papillectomy (n = 43) and pancreatoduodenectomy (n = 31). The estimated 5-year overall survival rate of all early ampullary tumors was 92%. Complete resection rate was significantly lower for endoscopic papillectomy patients versus pancreatoduodenectomy patients (48.8% vs. 100%; p < 0.001). Recurrence was more common in the endoscopic papillectomy group compared to the pancreatoduodenectomy group (16.3% vs. 3.2%; p = 0.128), but all recurrences were controllable by endoscopic treatment. The median length of hospital stay for the endoscopic papillectomy group was significantly shorter compared to the endoscopic papillectomy group (11 days vs. 42 days; p < 0.001). The Comprehensive Complication Index was significantly lower in the endoscopic papillectomy group compared to the pancreatoduodenectomy group (14.8 vs 22.6%; p = 0.002). Endoscopic papillectomy for early ampullary tumors is useful and may be an alternative treatment for pancreatoduodenectomy in selected cases., (© 2022. The Author(s).)

- Abstract
Background: Optimal treatment strategies for advanced hepatocellular carcinoma (HCC) with macroscopic portal vein tumor thrombus (PVTT) remain controversial. Therefore, this study aimed to assess the impact and predictive factors of hepatectomy for HCC with macroscopic PVTT., Methods: This study included 100 patients who presented with intraoperatively confirmed PVTT extending to the first portal branch (Vp3), main portal trunk, or opposite-side portal branch (Vp4) between June 2000 and December 2019. Their postoperative outcomes and predictive factors for survival were evaluated., Results: Of the 100 patients, 37 (37%) and 63 (63%) had Vp3 and Vp4 PVTTs, respectively. Moreover, 42 (42%) and 58 (58%) patients underwent R0/1 and R2 hepatectomies, respectively. The median survival time (MST) of all patients with Vp3/4 PVTT was 14.5 months; the 1- and 3-year overall survival rates were 59.6 and 16.8%, respectively. The MSTs of patients with Vp3 and Vp4 PVTTs were 16.1 and 14.3 months, respectively (P = 0.7098). The MSTs of patients who underwent R0/1 and R2 hepatectomies were 14.3 and 14.9 months, respectively (P = 0.3831). All assessed tumor factors (including the Vp status [Vp3 or Vp4], type of resection [R0/1 or R2], intrahepatic maximal tumor size, intrahepatic tumor number, and the existence of extrahepatic metastasis) did not influence the overall survival significantly., Conclusions: Tumor factors, such as the presence of a Vp3/4 PVTT, have a strong impact on survival; however, other multiple tumor factors have a limited impact. Hepatectomy can be an effective treatment option for HCC with Vp3/4 PVTT, and its indications should be considered., (© 2021. The Society for Surgery of the Alimentary Tract.)

- Abstract
Undifferentiated pleomorphic sarcoma(UPS)is a non-epithelial malignant tumor with a high rate of recurrence and metastasis. The frequent metastasis site is lung, lymph node, liver and bone. Pancreatic metastasis is rare. 71-year-old woman whose course after right foot UPS resection had been followed up at our hospital. But multiple bone and muscle metastasis occurred 1 year after operation. She had resection or radiation for the recurrence. 3 years after the first operation, PET-CT and EUS-FNA revealed pancreatic tail metastasis. The tumor grew up in 6 months, so we performed laparoscopic distal pancreatectomy. The patient recovered uneventfully and was discharged on post-operative day 14. Currently 5 years and 6 months have passed since the first surgery and she is alive. Function-preserving and minimally invasive surgery for UPS pancreatic metastasis is considered to be essential.

- Abstract
Introduction: Although the primary treatment option for hilar cholangiocarcinoma (HC) has been surgical resection, most patients present with unresectable advanced tumors at the time of diagnosis. Particle therapy (PT) holds great potential for HC, even though the anatomical proximity to the gastrointestinal tract prevents delivering a radical dose to the tumor. Space-making PT (SMPT), consisting of spacer placement surgery and subsequent PT, has been developed to minimize complications and maximize the therapeutic benefit of dose escalation for HC. This study aimed to conduct a dosimetric evaluation and examine the effectiveness of SMPT for the treatment of HC., Methods: Between 2007 and 2018, 12 patients with unresectable HC treated with SMPT were enrolled. The treatment outcomes and effectiveness of spacer placement surgery were evaluated through analyses of pre- and post-surgical parameters of dose-volume histograms., Results: All patients completed the planned SMPT protocol. The median survival time was 29.6 months, and the 1- and 3-year overall survival rates were 82.5% and 45.8%, respectively. The mean V95% value (volume irradiated with 95% of the planned treatment dose) of the gross tumor volume and clinical target volume after spacer placement surgery improved to 98.5% and 96.6% from preoperative values of 85.6% and 78.1%, respectively (p = 0.0196 and p = 0.0053, respectively). Grade 3 or higher adverse events after SMPT were seen in 6 patients., Discussion/conclusion: SMPT led to improvements in dosimetric parameters and showed good feasibility and excellent outcomes. SMPT can be a promising novel alternative for unresectable HC., (© 2022 S. Karger AG, Basel.)

- Abstract
Introduction: Although the relationship between systemic inflammatory responses and prognosis has been known in various cancers, it remains unclear which scores are most valuable for determining the prognosis of extrahepatic cholangiocarcinoma. We aimed to verify the usefulness of various inflammation-based scores as prognostic factors in patients with resected extrahepatic cholangiocarcinoma., Methods: We analyzed consecutive patients undergoing surgical resection for extrahepatic cholangiocarcinoma at our institution between January 2000 and December 2019. The usefulness of the following inflammation-based scores as prognostic factor was investigated: glasgow prognostic score (GPS), modified GPS, neutrophil-to-lymphocyte ratio, platelet to lymphocyte ratio, lymphocyte-to-monocyte ratio, prognostic nutrition index, C-reactive protein to albumin ratio (CAR), controlling nutritional status (CONUT), and prognostic index., Results: A total of 169 patients were enrolled in this study. Of the nine scores, CAR and CONUT indicated prognostic value. Furthermore, multivariate analysis for overall survival revealed that high CAR (>0.23) was an independent prognostic factor (hazard ratio: 1.816, 95% confidence interval: 1.135-2.906, p = 0.0129), along with lymph node metastasis and curability. There was no difference in tumor staging and short-term outcomes between the low CAR (≤0.23) and high CAR groups., Conclusions: CAR was the most valuable prognostic score in patients with resected extrahepatic cholangiocarcinoma., (© 2022 S.

- Abstract
A woman in her 80s was diagnosed with pancreatic tail cancer by endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). We performed laparoscopic distal pancreatectomy followed by adjuvant chemotherapy with S-1 for 6 months. One year after surgery, contrast-enhanced computed tomography revealed a 15 mm mass in the posterior wall of the gastric body. EUS showed a hypoechoic mass in the muscular layer in the gastric wall, which was diagnosed as adenocarcinoma by FNA. We diagnosed gastric wall recurrence due to needle tract seeding(NTS)following EUS-FNA and performed partial gastrectomy. Histopathological diagnosis was gastric wall recurrence of pancreatic cancer. Since NTS following EUS-FNA can be proven only by the presence of gastric wall recurrence after surgery for pancreatic body or tail cancer, the actual risk of NTS including peritoneal dissemination is not clear and may have been underestimated. In case of resectable pancreatic body or tail cancer, indication for EUS-FNA should be carefully considered.

- Abstract
Background: Although liver transplantation is widely accepted as the therapeutic strategy for end-stage liver failure, complication of hepatic venous outflow obstruction remains lethal. Currently, ensuring a single wide orifice in both the graft and recipient inferior vena cava has been proposed to avoid hepatic venous outflow obstruction with no theoretical concept., Methods: We herein report a standardization technique for the reconstruction of the hepatic vein based on the causal analysis., Results: During the put-in process, the graft must be positioned in contact with the recipient diaphragm and slightly pushed to the cranial direction to simulate the state after abdominal closure. Because there is no extra space between the graft and diaphragm, the graft could not rotate about the anastomotic site of the inferior vena cava toward the diaphragm after abdominal closure as the intestinal pressure increases, and accordingly hepatic venous outflow obstruction does not develop., Conclusions: With this concept, all transplant surgeons can successfully and easily perform hepatic vein reconstruction without total clamping of the inferior vena cava and without outflow block., (Copyright © 2021 Elsevier Inc.

- Abstract
Background: Radiological detection of small liver metastasis or peritoneal metastasis is still difficult, and some patients with biliary tract cancer (BTC) are unresectable after laparotomy. Staging laparoscopy may help avoid unnecessary laparotomy. However, which category of BTC is amenable with staging laparoscopy remains unclear., Aim: To clarify the risk factors for occult metastasis in patients with BTC., Methods: Medical records of patients with BTC who underwent surgery at our institution between January 2008 and June 2014 were retrospectively reviewed. The patients were divided into two groups, according to resection or exploratory laparotomy (EL). Preoperative laboratory data, including inflammation-based prognostic scores and tumor markers, were compared between the two groups. Prognostic importance of detected risk factors was also evaluated., Results: A total of 236 patients were enrolled in this study. Twenty-six (11%) patients underwent EL. Among the EL patients, there were 16 cases of occult metastasis (7 liver metastases and 9 abdominal disseminations). Serum carcinoembryonic antigen level, carbohydrate antigen 19-9 level, neutrophil-lymphocyte ratio and modified Glasgow prognostic score were significantly higher in the EL group than in the resected group, and these factors were prognostic. Among these factors, carcinoembryonic antigen > 7 ng/mL was the most useful to predict occult metastasis in BTC. When patients have more than three of these positive factors, the rate of occult metastasis increases., Conclusion: Inflammation-based prognostic scores and tumor markers are useful in detecting occult metastasis in BTC; based on these factors, staging laparoscopy may reduce the rate of EL., Competing Interests: Conflict-of-interest statement: The authors declare that they have no financial relationships to disclose., (©The Author(s) 2021.

- Abstract
The prognosis of hepatocellular carcinoma (HCC) presenting with inferior vena cava tumor thrombus (IVCTT) is extremely poor. The aim of this study was to reveal the postoperative course and to identify patients who have survived surgical hepatectomy among HCC patients with IVCTT. Between January 2006 and December 2018, 643 patients underwent surgical hepatectomy for HCC at Kobe University Hospital. Among them, 20 patients were categorized as Vv3 according to the Japanese staging system. We retrospectively collected detailed data on these patients. The statistical, clinical, and pathological data were recorded prospectively and analyzed retrospectively. The median survival time was 9.8 months. Among all patients, 11 (55%) achieved R0 resection, and only two survivors were from this group. The number of tumors (solitary vs. multiple; p=0.050) and pathological Vp (pVp0 vs. other; p=0.009) were identified as risk factors for overall survival in the univariate analysis. In the multivariate analysis, pathological Vp (pVp0 vs. other; p=0.037) was identified as a significant prognostic factor for survival. Pathological Vp affected overall survival among IVCTT patients; the median survival time was 53.7 months with pVp0, 10.2 months with pVp1, and 8.8 months with pVp2-4 (p=0.035). For patients with IVCTT, surgical hepatectomy should be indicated only for those who do not have portal vein invasion and could achieve R0 resection.

- Abstract
Background: Only few studies in literature have analyzed the clinical effects of peritoneal lavage status in biliary tract cancers., Aim: We aimed to assess the effect of cytology-positive peritoneal lavage on survival for patients with biliary tract cancer who underwent curative resection., Methods: The KHBO1701 study was a multi-institutional retrospective study that assessed the clinical effects of peritoneal lavage cytology in biliary tract cancers. Using clinicopathological data from 11 Japanese institutions, we compared long-term outcomes between patients with cytology-positive and cytology-negative peritoneal lavage., Results: Of 169 patients who underwent curative resection, 164 were cytology-negative, and five were cytology-positive. The incidence of portal invasion and preoperative carbohydrate antigen 19-9 levels were higher in the cytology-positive group than in the cytology-negative group. The incidence of peritoneal metastatic recurrence was also higher, and overall survival tended to be worse in the cytology-positive group. In contrast, recurrence-free survival was similar between the cytology-negative and cytology-positive groups., Conclusions: The positive status of peritoneal lavage cytology could moderately affect the survival of patients with biliary tract cancers. Given that surgical resection is the only curative treatment option, it may be acceptable to resect biliary tract cancers without other non-curative factors, regardless of peritoneal lavage cytology status., (© 2020 The Authors.
