STUDY OBJECTIVES: To facilitate marking and to reduce its complications, we performed barium marking using an ultrathin bronchoscope with virtual bronchoscopic (VB) navigation before thoracoscopic surgery for small pulmonary peripheral lesions. We then evaluated the feasibility, safety, and efficacy of this technique. DESIGN: A pilot study. SETTING: A tertiary teaching hospital. PATIENTS: The subjects were consecutive patients with small pulmonary peripheral lesions (ie,

The efficacy of early enteral nutrition after esophageal cancer surgery has been reported. However, the choice of formula and management of diarrhea are important to achieve the goal of enhanced recovery after surgery. The aim of this study is to assess the frequency of diarrhea/completion rate of enteral nutrition regimen as primary endpoints and the postoperative nutritional status/body composition analysis/operative morbidity as secondary endpoints was compared between the two nutrition groups. Among the 122 patients who underwent esophagectomy for esophageal cancer between December 2015 and September 2017, 67 patients who met the eligibility criteria were randomly assigned to receive enteral nutrition with either HINE E-GEL® (HINE group; n  = 33) or MEIN® (MEIN group; n  = 34). The incidence of diarrhea was significantly lower in the HINE group (18.2 % vs. 64.7 %, P  < 0.001). The score of Bristol scale of POD 6/7 was significantly lower in the HINE group (P  = 0.019/ P  = 0.006, respectively). The completion rate of enteral nutrition regimen was significantly higher in the HINE group (97.4 % vs. 86.6 %, P  = 0.002). The Controlling Nutritional Status scores and total protein levels at 6 months after surgery were significantly better in the HINE group (P  = 0.030 and P  = 0.023, respectively), indicating improved tendency in nutritional status in the HINE group. However, there were no significant differences in Prognostic Nutritional Index values, blood test results, rapid turnover proteins, body mass index, or body composition between the two groups. HINE E-GEL compared with MEIN may reduce the frequency of diarrhea, enabling patients to adhere to the scheduled enteral nutrition plan. Also, maintenance of nutritional status with HINE E-GEL was comparable or potentially better in some nutrition components to that with MEIN, indicating that HINE E-GEL can be an option for enteral nutrition following esophageal surgery to achieve the goal of successful completion of scheduled enteral nutrition and smooth transition to the normal diet.

Background: The aim of this study was to evaluate the newly established oncological criteria of resectability of hepatocellular carcinoma (HCC) for selecting suitable candidates for systemic and combination therapy., Methods: The data of 156 consecutive HCC patients with intrahepatic target nodules who had initially received systemic therapy (lenvatinib and atezolizumab plus bevacizumab) were reviewed. The patients were classified into three groups according to the novel oncological criteria for resectability (R, resectable; BR1, borderline resectable 1; and BR2, borderline resectable 2). The prognostic ability and clinical utility for selecting this population to receive combined use of multiple systemic sequential and locoregional therapy was then evaluated. Combined use of systemic sequential therapy with more than two agents and locoregional treatment was defined as multidisciplinary combination therapy (MCT), while systemic sequential therapy only and repeated locoregional treatment was defined as a single treatment procedure (STP)., Results: Patients classified as R and BR1 had significantly better overall survival (OS) compared with BR2 (R vs. BR2, p = 0.012; BR1 vs. BR2, p = 0.004). However, there was no significant difference between R and BR1 (p = 1.000), in spite of significantly worse oncological status in the BR1 patients. Following a R0 resection and MCT, the BR1 patients had significantly better OS compared with those receiving STP or no additional treatment (median OS, not reached vs. 25.2 months and 20.1 vs. 11.3 months, respectively; p = 0.034)., Conclusions: In patients with advanced HCC with intrahepatic target nodules the BR1 category is one of the favorable candidates for selecting those to be treated with MCT strategies., (© 2024 Japan Society of Hepatology.)

Background: Recent advancements in systemic therapy for hepatocellular carcinoma (HCC) necessitate the establishment of resectability criteria for advanced HCC., Methods: A questionnaire survey sought to clarify the perspectives of Japanese expert hepatobiliary surgeons regarding surgical indications for HCC. Thirty-one questions were used to determine when surgery is strongly recommended (resectable: R) or not recommended (unresectable: UR)., Results: A total of 351 responses were obtained. While 64.7% of the respondents considered solitary tumors as being R, irrespective of size, opinions diverged on the upper limit of the number of tumors/tumor size for R: (1) up to three nodules with no size limit (27.9%), (2) up to three nodules ≤5 cm in diameter each (21.4%) and (3) up to three nodules ≤3 cm in diameter each (19.4%). Vp1, Vp2, Vp3, and Vp4 were considered as being R by 90.9%, 70.7%, 39.0%, and 8.0% of respondents, respectively. Half of the respondents indicated they would consider resection even for cases with extrahepatic spread under limited conditions., Conclusions: The current views of Japanese expert surgeons on the resectability criteria for HCC were clarified for the first time. The findings could serve as a basis for preparing expert consensus statements on the resectability criteria for HCC., (© 2024 Japanese Society of Hepato-Biliary-Pancreatic Surgery.)

Introduction: The phase III REFLECT trial demonstrated that lenvatinib was superior to sorafenib in terms of progression-free survival (PFS), time to progression, and objective response rate (ORR) for patients with unresectable hepatocellular carcinoma (HCC). This study assessed the efficacy and safety of preoperative lenvatinib therapy for patients with oncologically or technically unresectable HCC., Methods: In this multicenter single-arm phase II trial, patients with advanced HCC and factors suggestive of a poor prognosis (macroscopic vascular invasion, extrahepatic metastasis, or multinodular tumors) were enrolled. Patients with these factors, even with technically resectable HCC, were defined as oncologically unresectable because of the expected poor prognosis after surgery. After 8 weeks of lenvatinib therapy, the patients were assessed for resectability, and tumor resection was performed if the tumor was considered technically resectable. The primary endpoint was the surgical resection rate. The secondary endpoints were the macroscopic curative resection rate, overall survival (OS), ORR, PFS, and the change in the indocyanine green retention rate at 15 min as measured before and after lenvatinib therapy. The trial was registered with the Japan Registry of Clinical Trials (s031190057)., Results: Between July 2019 and January 2021, 49 patients (42 oncologically unresectable patients and 7 technically unresectable patients) from 11 centers were enrolled. The ORR was 37.5% based on mRECIST and 12.5% based on RECIST version 1.1. Thirty-three patients underwent surgery (surgical resection rate: 67.3%) without perioperative mortality. The surgical resection rate was 76.2% for oncologically unresectable patients and 14.3% for technically unresectable patients. The 1-year OS rate and median PFS were 75.9% and 7.2 months, respectively, with a median follow-up period of 9.3 months., Conclusions: The relatively high surgical resection rate seen in this study suggests the safety and feasibility of lenvatinib therapy followed by surgical resection for patients with oncologically or technically unresectable HCC., Competing Interests: E.H. reports honoraria from Eisai, Chugai Pharmaceutical, Bayer, Eli Lilly, and Takeda Pharmaceutical.

Purpose: Optimal choice of diuretics in perioperative management remains unclear in enhanced recovery after liver surgery. This study investigated the efficacy and safety of tolvaptan (oral vasopressin V2-receptor antagonist) in postoperative management of patients with liver injury and hepatocellular carcinoma., Methods: The patients clinically diagnosed with liver cirrhosis were included in this study. Clinical outcomes of 51 prospective cohort managed with a modified postoperative protocol using tolvaptan (validation group) were compared with 83 patients treated with a conventional management protocol (control group)., Results: Postoperative urine output were significantly larger and excessive body weight increase were reduced with no impairment in renal function or serum sodium levels in the validation group. Although the total amount of discharge and trend of serum albumin level were not significantly different among the groups, global incidence of postoperative morbidity was less frequent (19.6% vs. 44.6%, P=0.005) and postoperative stay was significantly shorter (8 days vs.10 days, P=0.008) in the validation group compared with the control group., Conclusions: Tolvaptan could be safely used for the patients with injured liver in postoperative management after hepatectomy and potentially advantageous in the era of enhanced recovery after surgery with its strong diuretic effect and better fluid management., (© 2023.

Background: The aim of this study was to evaluate the clinical impact of a combination of systemic sequential therapy and locoregional therapy on the long-term survival of patients with Barcelona Clinic Liver Cancer (BCLC) stage C hepatocellular carcinoma (HCC)., Methods: Sixty-four consecutive patients with intrahepatic target nodules who had initially received systemic therapy (lenvatinib and atezolizumab plus bevacizumab) were reviewed. The clinical impact of the combined use of systemic sequential therapy and locoregional therapy was evaluated by determining overall survival (OS). The combined use of systemic sequential therapy with more than two agents and locoregional treatment was defined as multidisciplinary combination therapy (MCT), while only systemic sequential therapy and repeated locoregional-treatment was defined as a single treatment procedure (STP)., Results: R0 resection, MCT, and STP resulted in significantly better OS compared with no additional treatment (median OS, not reached vs. 18.2 months and 12.6 vs. 8.1 months, respectively; p = 0.002). Multivariate analysis confirmed that the use of R0 resection and MCT were associated with better OS (hazard ratio [HR]; 0.053, p = 0.006 and 0.189, p < 0.001, respectively) compared with that for STP (HR; 0.279, p = 0.003)., Conclusions: MCT is may effective in patients with BCLC stage C HCC and intrahepatic target nodules who have previously received systemic therapy-based treatment.

Background: Pancreatic head resection following proximal gastrectomy jeopardizes the blood flow of the remnant stomach owing to right gastroepiploic conduit sacrifice, thereby necessitating total gastrectomy. However, owing to its high invasiveness, concomitant remnant total gastrectomy with pancreatectomy should be avoided as much as possible. Herein, we describe our experience of total pancreatectomy with right gastroepiploic conduit preservation in a patient with a history of proximal gastrectomy and reconstruction by jejunum interposition., Case Presentation: A 78-year-old woman with a history of gastric cancer was followed up at our institute for multiple intraductal papillary mucinous neoplasm, and main pancreatic duct stricture in the pancreatic head was newly detected. The cystic lesion was extended to the pancreatic body. Proximal gastrectomy and reconstruction by jejunal interposition were previously performed, and the mesenteric stalk of the interposed jejunum was approached through the retrocolic route. We planned total pancreatectomy with right gastroepiploic conduit preservation. Following adhesiolysis, the interposed jejunum and its mesentery lying in front of the pancreas were isolated. The arterial arcade from the common hepatic artery to the right gastroepiploic artery was detached from the pancreas. Furthermore, the right gastroepiploic vein was isolated from the pancreas. The pancreatic body and tail were pulled up in front of the remnant stomach, and the splenic artery and vein were resected. The pancreatic body and tail were pulled out to the right side, and the pancreatic head was divided from the pancreatic nerve plexus to the portal vein. The jejunal limb for entero-biliary anastomosis was passed through the hole behind the superior mesenteric artery and vein, and gastrointestinal anastomosis using the antecolic route and Braun anastomosis were performed., Conclusions: To avoid remnant total gastrectomy, right gastroepiploic conduit preservation is an optional procedure for pancreatic head resection in patients who have undergone proximal gastrectomy with reconstruction by jejunal interposition., (© 2023.

Background: Currently used treatment algorithms were originally established based on the clinical outcomes of the initial treatment for primary hepatocellular carcinoma (HCC), and no strong evidence exists yet to suggest if these algorithms could also be applicable to patients with recurrent HCC after surgery. As such, this study sought to explore an optimal risk stratification method for cases of recurrent HCC for better clinical management., Methods: Among the 1616 patients who underwent curative resection for HCC, the clinical features and survival outcomes of 983 patients who developed recurrence were examined in detail., Results: Multivariate analysis confirmed that both the disease-free interval (DFI) from the previous surgery and tumor stage at recurrence were significant prognostic factors. However, the prognostic impact of DFI seemed different according to the tumor stages at recurrence. While curative-intent treatment showed strong influence on survival [hazard ratio (HR), 0.61; P < 0.001] regardless of the DFI in patients with stage 0 or stage A disease at recurrence, early recurrence (< 6 months) was a poor prognostic marker in patients with stage B disease. The prognosis of patients with stage C disease was exclusively influenced by the tumor distribution or choice of treatment than by the DFI., Conclusions: The DFI complementarily predicts the oncological behavior of recurrent HCC, with its predictive value differing depending on the tumor stage at recurrence. These factors should be considered for selection of the optimal treatment in patients with recurrent HCC after curative-intent surgery., (© 2023. Society of Surgical Oncology.)

Background: This study aimed to explore the efficacy of gadoxetic acid-enhanced (Gd-EOB) magnetic resonance imaging (MRI) in surgical risk estimation among patients with marginal hepatic function estimated by indocyanine green (ICG) clearance test., Methods: This analysis focused on 120 patients with marginal hepatic functional reserve (ICG clearance rate of future liver remnant [ICG-Krem] < 0.10). Preoperative Gd-EOB MRI was retrospectively reviewed, and the remnant hepatocyte uptake index (rHUI) was calculated for quantitative measurement of liver function. The predictive power of rHUI for posthepatectomy liver failure was compared with several clinical measures used in current risk estimation before hepatectomy., Results: Receiver operating curve analysis showed that rHUI had the best predictive power for posthepatectomy liver failure among the tested variables (ICG-R15, ICG-Krem, albumin + bilirubin score, and albumin + ICG-R15 score). Cross-validation showed that a threshold of 925 could be the best cut-off value for estimating the postoperative risk of liver failure with sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio of 0.689, 0.884, 5.94, and 0.352, respectively., Conclusion: rHUI could be a sensitive substitute measure for posthepatectomy liver failure risk estimation among patients with marginal hepatic functional reserve., (© 2023.

Purpose: Tumor sidedness (hepatic side vs. peritoneal side) reportedly predicts microvascular invasion and survival outcomes of T2 gallbladder cancer, although the actual histopathological mechanism is not fully understood., Methods: The clinical relevance of tumor sidedness was revisited in 84 patients with gallbladder cancer using histopathological analysis of the vascular density of the gallbladder wall., Results: Hepatic-side tumor location was associated with overall survival (OS) (hazard ratio [HR], 13.62; 95% confidence interval [CI], 2.09-88.93) and recurrence-free survival (RFS) (HR, 8.70; 95% CI, 1.36-55.69) in T2 tumors. The Adjusted Kaplan-Meier curve indicated a clear survival difference between T2a (peritoneal side) and T2b (hepatic side) tumors (P = 0.006). A review of 56 pathological specimens with gallbladder cancer and 20 control specimens demonstrated that subserosal vascular density was significantly higher on the hepatic side of the gallbladder, regardless of the presence of cancer (P < 0.001). Multivariate analysis also confirmed that higher subserosal vascular density was significantly associated with poor OS (HR, 1.73; 95% CI, 1.10-2.73 per 10 microscopic fields) and poor RFS (HR, 1.62; 95% CI, 1.06-2.49) in T2  gallbladder cancer., Conclusion: Higher subserosal vascular density may account for the higher incidence of cancer spread and the poor prognosis of T2b gallbladder cancer., (© 2023.

Background: The aims of this study were to evaluate the clinical impact of curative-intent subsequent treatment on overall prognosis in lenvatinib-treated hepatocellular carcinoma (HCC) patients., Methods: Eighty-three consecutive patients with intrahepatic target nodules who received lenvatinib were reviewed. The clinical impact of curative-intent subsequent treatments was investigated through analysis of overall survival (OS) according to pathological deterioration stratified by mALBI grade., Results: In patients with mALBI grade 1 and 2a liver function, R0 resection and lenvatinib-transarterial chemoembolization (lenvatinib-TACE) sequential therapy resulted in significantly better OS compared with other, non-curative-intent subsequent therapy and lack of additional treatment (median OS, 37.6 vs 29.0 months and 17.1 vs 8.9 months, respectively; P < 0.001). Multivariate analysis confirmed that use of R0 resection and lenvatinib-TACE sequential therapy were associated with better OS (hazard ratio [HR], 0.021; P < 0.001 and 0.108; P < 0.001) compared with other, non-curative-intent subsequent treatment (HR 0.256; P = 0.010). In contrast, in patients with mALBI grade 2b liver function, multivariate analysis confirmed higher treatment efficacy for non-curative-intent subsequent treatment with respect to OS (HR 0.041; P < 0.001) compared with R0 resection and lenvatinib-TACE sequential therapy (HR 0.057; P = 0.027 and 0.063; P = 0.001)., Conclusion: Curative-intent subsequent treatment is more useful for HCC patients with better liver function (mALBI grade 1 and 2a) and intrahepatic target nodules who have received lenvatini b-based treatment., (© 2022.

Purpose: To investigate if body composition parameters measured by bioelectrical impedance analysis (BIA) and are reportedly correlated with clinical outcomes of patients undergoing digestive tract surgery could be useful for reliably evaluating the perioperative risk in patients undergoing hepatectomy., Methods: Consecutive 200 patients who underwent BIA before hepatectomy were retrospectively reviewed. A risk prediction model for postoperative morbidity was created using the initial 100 patients, and its performance was validated using the remaining 100 patients., Results: Based on the correlation with postoperative morbidity, a novel risk prediction model, the protein-edema score, was created using net protein weight and extracellular water/total body water ratio measured through BIA. The protein-edema score (score 0 vs. ≥ 1) showed a reproducible correlation with Clavien-Dindo 2 or greater postoperative morbidity in the validation set (17.7% vs. 46.4%, P = 0.002) as observed in the training set (18.8% vs. 49.0%, P = 0.002) after statistical adjustment. Similar tendency was also confirmed in Clavien-Dindo 3a or greater postoperative morbidity (5.9% vs. 18.2%, P = 0.037) and postoperative refractory ascites (5.5% vs. 17.4%, P = 0.037) in the validation set., Conclusions: The protein-edema score created based on BIA is significantly correlated with postoperative morbidity in patients undergoing liver resection., (© 2023.

Introduction: When lenvatinib is administered to people with hepatocellular carcinoma (HCC), tumor blood flow is reduced due to the inhibition of the vascular endothelial growth factor receptor (VEGFR) and fibroblast growth factor receptor (FGFR). Few studies have examined the decrease in tumor blood flow with respect to changes in tumor blood vessels (TBVs) in clinical practice. We investigated the mechanism of tumor blood flow control by investigating changes in the diameter of relatively large TBVs in large-sized lesions with high blood flow., Methods: From January 2011 to October 2021, patients receiving lenvatinib for unresectable intrahepatic HCC at Toranomon Hospital, Tokyo, Japan, were considered for inclusion. We investigated the TBV diameter in the arterial phase of dynamic computed tomography before treatment and its change over time (2-12 weeks after lenvatinib initiation). The relationship between changes in TBV diameter and prognosis was also examined., Results: Of 114 patients treated with lenvatinib for HCC, 26 patients who had intrahepatic lesions with a tumor diameter of 30 mm or more enrolled in the study. The median tumor and TBV diameters before treatment were 58 mm and 2.55 mm, respectively. Twenty-five patients (96%) had a shrinkage in TBV diameter 2-12 weeks after lenvatinib administration. The maximum TBV diameter shrinkage of 20% or more was observed in 19 patients (73%), and progression-free survival was prolonged in these patients compared to the group with less than 20% TBV diameter shrinkage (p = 0.039)., Discussion/conclusion: Due to the antiangiogenic effect of lenvatinib, a shrinkage in the TBV diameter of HCC was observed. The shrinkage of TBV may be regarded as a process of normalization of TBVs. The shrinkage of TBVs in imaging analysis may be associated with improved prognosis; however, additional studies are still required., (© 2022 The Author(s). Published by S. Karger AG, Basel.)

Background: Rectal neuroendocrine neoplasms can induce liver metastasis. However, few reports exist on the associated long-term recurrence rates. We report a case of liver metastasis identified 15 years after rectal neuroendocrine neoplasm resection., Case Presentation: A 50-year-old woman was on semi-annual follow-up after undergoing mastectomy for breast cancer (pT1N0M0) and low anterior resection for grade 1 rectal neuroendocrine neoplasm (pT1b, ly1, v1). Fifteen years postoperatively, a 7-mm hyperechoic mass was identified at liver segment 6. Magnetic resonance imaging revealed a slight growth of the mass. Positron emission tomography/computed tomography revealed radiotracer accumulation in the lesion. Laparoscopic hepatectomy was performed. The histopathological diagnosis was grade 2 neuroendocrine neoplasm. The pathological findings and clinical course indicated the tumor originated in the rectum., Conclusions: Our findings highlight the need to reassess the optimal postoperative follow-up period for patients with rectal neuroendocrine neoplasm., (© 2022.

Background: Patients with esophageal cancer often feel depressed and are fearful of metastasis and death. Esophagectomy is an invasive procedure with a high incidence of complications. The objective of this study was to examine the association between psychological distress on each points of the treatment of esophageal cancer and stress coping strategy., Methods: In total, 102 of 152 consecutive patients who attended the outpatient clinic at Toranomon Hospital between April 2017 and April 2019 met the eligibility criteria for inclusion in this study. Questionnaires designed to identify psychological distress and stress coping strategies were longitudinally administered at 5 time points from the time of the first outpatient consultation to 3 months after esophagectomy., Results: Although 'fighting spirit' (OR 0.836, 95% CI 0.762-0.918; p < 0.001) and 'anxious preoccupation' (OR 1.482, 95% CI 1.256-1.748; p < 0.001) were strongly related to psychological distress before treatment, as time of treatment passes, 'helpless/hopeless' (OR 1.337, 95% CI 1.099-1.626; p = 0.004) was strongly related to psychological distress after esophagectomy. There were no relationships between psychological distress and individual patient characteristics, with the exception of 'history of surgery' and 'final staging'. The concordance index was 0.864 at time 1, 0.826 at time 2, 0.839 at time 3, 0.830 at time 4, and 0.840 at time 5., Conclusions: The relationship between psychological distress and the Coping strategies was stronger on each points of the treatment of esophageal cancer than that between psychological distress and individual patient characteristics. This study uses prospective basic clinical data and may provide the baseline information for risk stratification for psychological management and for future clinical studies in these patients., (© 2022.

Background: Increasing number of patients with advanced hepatocellular carcinoma (HCC) has recently achieved salvage interventions after introduction of new biologic agents, while there are insufficient data to determine if such additional intervention(s) after treatment with newer biologic agents are truly advantageous for patients with advanced HCC., Methods: The clinical records of 107 consecutive patients who underwent lenvatinib treatment for advanced HCC were extensively reviewed and the prognostic advantages of individual additional treatments after lenvatinib treatment were investigated through a regression analysis considering time-dependent covariates., Results: Multivariate analysis revealed that R0 resection or curative-intent radiofrequency ablation (RFA) (hazard ratio [HR], 0.07; 95% CI, 0.01-0.32), transarterial chemoembolization or transarterial infusion therapy (HR, 0.39; 95% CI, 0.19-0.81), and subsequent line of systemic therapy (HR, 0.25; 95% CI, 0.10-0.63) were associated with improved disease-specific survival (DSS), while R2 resection or palliative-intent RFA showed no correlation with DSS. The best response during lenvatinib therapy, nutritional status, plasma des-gamma-carboxyprothrombin level, a baseline CT enhancement pattern, and BCLC stage were also selected as independent predictors for DSS. Among the various treatments performed after lenvatinib therapy, R0 resection also showed clear prognostic advantage in both progression-free survival (HR, 0.30; 95% CI, 0.16-0.58) and time-to-treatment failure (HR, 0.08; 95% CI, 0.02-0.39), suggesting that successful conversion to surgery may prolong survival outcomes through prolonged cancer-free interval in advanced HCC., Conclusions: Additional intervention(s)/treatment(s) after lenvatinib therapy for advanced HCC may have prognostic advantage in strictly selected populations. Successful conversion to curative resection may offer survival benefit with acceptable clinical outcomes., (© 2022. The Society for Surgery of the Alimentary Tract.)
