Efficacy of 1-Kestose Supplementation in Patients with Pancreatic Ductal Adenocarcinoma: A Randomized Controlled Pilot Study.

Less than half of all patients diagnosed with pancreatic ductal adenocarcinoma (PDAC) respond to chemotherapy, and the prognosis of PDAC is poor, which may be mediated by the gut microbiota. We investigated the clinical improvement effects of 1-kestose, a fructooligosaccharide, on PDAC chemotherapy in this single-center, randomized, controlled pilot trial conducted at Fujita Health University Hospital, which enrolled patients with PDAC. The trial included 1-kestose administration and non-administration groups.

The Effects of 1-Kestose on the Abundance of Inflammation-Related Gene mRNA in Adipose Tissue and the Gut Microbiota Composition in Rats Fed a High-Fat Diet.

Chronic inflammation in adipose tissue is thought to contribute to insulin resistance, which involves the gut microbiota. Our previous studies have demonstrated that ingestion of 1-kestose can alter the gut microbiota composition, increase cecal butyrate levels, and improve insulin resistance in Otsuka Long-Evans Tokushima Fatty (OLETF) rats. Additionally, we found that 1-kestose supplementation ameliorated insulin resistance in obese rat models fed a high-fat diet (HFD), although the effects of 1-kestose on the abundance of inflammation-related gene in adipose tissue and gut microbiota composition in these rats were not explored.

Impact of GLIM criteria-based malnutrition diagnosis on outcomes following liver resection for hepatocellular carcinoma.

Background: The Global Leadership Initiative on Malnutrition (GLIM), comprising several of the major global clinical nutrition societies, suggested the world's first criteria for diagnosis of the severity of malnutrition. However, the impact of the resulting diagnosis on patient outcomes for those with hepatocellular carcinoma (HCC) following liver resection (LR) has not been investigated.

Methods: A retrospective analysis of 293 patients with HCC who underwent LR between January 2011 and December 2018 was performed.

The Usefulness of Total Tumor Volume as a Prognostic Factor and in Selecting the Optimal Treatment Strategy of Chemotherapeutic Intervention in Patients with Colorectal Liver Metastases.

Background: Few reports have discussed the association between total tumor volume (TTV) and prognosis in patients with colorectal liver metastases (CRLM). The present study aimed to evaluate the usefulness of TTV for predicting recurrence-free survival and overall survival (OS) in patients receiving initial hepatic resection or chemotherapy, and to investigate the value of TTV as an indicator for optimal treatment selection for patients with CRLM.

Patients And Methods: This retrospective cohort study included patients with CRLM who underwent hepatic resection (n = 93) or chemotherapy (n = 78) at the Kobe University Hospital.

Transarterial chemoembolization for liver metastases of a pancreatic neuroendocrine neoplasm: a single-center experience.

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%.

Prognostic Impact of Malnutrition Diagnosed by the GLIM Criteria for Resected Extrahepatic Cholangiocarcinoma.

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.

Factors Predicting Over-Time Weight Increase After Liver Transplantation: A Retrospective Study.

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.

Outcomes of the Sequential Treatment of Unresectable Hepatocellular Carcinoma Using Lenvatinib.

Background/aim: The chemotherapeutic landscape for hepatocellular carcinomas (HCCs) has changed dramatically with the availability of several treatment options. This study aimed to assess the long-term outcomes of lenvatinib treatment and analyze its feasibility in the sequential treatment of HCCs.

Patients And Methods: Eighty-five consecutive patients who received lenvatinib for unresectable HCCs were investigated retrospectively.

Assessment of serum and drain fluid bilirubin concentrations in liver transplantation patients.

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.

Potential Role of Surgical Resection for Gallbladder Cancer in Elderly Patients.

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.

Rechallenge With Lenvatinib After Atezolizumab Plus Bevacizumab Treatment for Hepatocellular Carcinoma.

Background/aim: Atezolizumab plus bevacizumab and lenvatinib are the key drugs in the current systemic chemotherapeutic regimen for hepatocellular carcinoma (HCC). Studies have reported the potential effectiveness of lenvatinib introduction after an atezolizumab plus bevacizumab treatment; however, the therapeutic effectiveness of a lenvatinib rechallenge after an atezolizumab plus bevacizumab treatment remains unclear.

Patients And Methods: Thirteen consecutive patients who were rechallenged with lenvatinib after clinical failure following treatments with lenvatinib and atezolizumab plus bevacizumab were included.

Standardization of laparoscopic anatomic liver resection of segment 2 by the Glissonean approach.

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.

Hepatectomy versus sorafenib for advanced hepatocellular carcinoma with macroscopic portal vein tumor thrombus: A bi-institutional propensity-matched cohort study.

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.

Use of a short cartridge stapler is beneficial in pancreatic transection at the neck during laparoscopic distal pancreatectomy.

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.

Suitability of Laparoscopic Liver Resection of Segment VII: a Retrospective Two-Center Study.

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.

Impact of COVID-19 on living donor liver and kidney transplantation programs in Japan in 2020.

Background: Although many transplant programs have been forced to suspend living donor transplants due to the emergence of coronavirus disease (COVID-19), there are relatively few real-time databases to assess center-level transplant activities. We aimed to delineate the actual impact of COVID-19 on living donor transplant programs and the resumption process in Japan.

Methods: In a nationwide survey, questionnaires were sent to 32 liver transplant programs that had performed at least more than one case of living donor liver transplantation in 2019 and 132 kidney transplant programs that had performed more than one living donor kidney transplantation in 2018.

Clinicopathological variables and risk factors for lung recurrence after resection of pancreatic ductal adenocarcinoma.

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.

Prognostic Impact of Inflammation-Based Scores for Extrahepatic Cholangiocarcinoma.

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.
