Background: Although curative resection with vascular reconstruction improves the prognosis of blood-invading locally advanced hepatobiliary tumors, the mortality and morbidity of the procedure remains unclear. This study aimed to clarify the risk factors associated with mortality and morbidity in patients undergoing liver resection with vascular reconstruction. Methods: This retrospective observational study included 1215 patients undergoing hepatectomy of more than one section with vascular reconstruction, except for left lateral sectionectomy registered in the National Clinical Database (NCD) between 2015 and 2019. The rates of surgical mortality and relevant clinical factors were evaluated. Results: Among the four types of vascular reconstruction, portal venous reconstruction was frequently performed in 724 patients (59.6% of the enrolled patients). Surgical mortality was 8.1%. Patients with hepatic artery reconstruction had the highest surgical mortality rate of 15.8%. In other types of reconstruction, surgical mortality was 9.1% in the portal vein, 5.2% in inferior vena cava, and 4.9% in hepatic vein. Factors significantly associated with surgical mortality include age, sex (male), preoperative comorbidity (American Society of Anesthesiologists grade >3, respiratory distress, diabetes, preoperative pneumonia, weight loss, and obstructive jaundice), poorer liver functional reserve (indocyanine green retention rate at 15 min and prothrombin time/international normalized ratio >1.1) and accompanying biliary reconstruction. Conclusions: The NCD revealed the detailed status of liver resection combined with vascular reconstruction in Japan. Based on the results of this analysis, understanding the factors that influence the outcome and postoperative course of each procedure will provide patients with accurate information and opportunities to improve future outcomes.

Nowadays, the novel molecular targeting chemotherapy provides possibility of safe hepatectomy for progressive hepatocellular carcinoma (HCC). Further, combination of the conventional transarterial chemoembolization (TACE) may add an effect of tumor shrink. We present a successful radical hepatectomy for a large HCC located in segment 1 accompanied with the preoperative Lenvatinib (LEN)-TACE sequential treatment. We present a woman patient without any complaints who had a 7 cm-in-size of solitary HCC compressing vena cava and right portal pedicle. To achieve radical hepatectomy by tumor shrinking, LEN-TACE for 2 months. After confirming downsizing or devascularization of the HCC, we scheduled radical posterior sectionectomy combined with caudate lobectomy according to tumor location and expected future remnant liver volume from three-dimensional computed tomography simulation before surgery. Under the thoraco-abdominal incision laparotomy, we safely achieved scheduled radical hepatectomy without any vascular injuries. The postoperative course was uneventful and no tumor recurrence were observed for 1 year. Histological findings showed the Japan TNM stage III HCC with 70% necrosis. The multi-modal strategy of LEN-TACE followed by radical hepatectomy by confirming downsizing or devascularization in tumor is supposed to be useful and would be a preoperative chemotherapy option, and promising for curative treatment in HCC patients with progressive or large HCC, which may lead to safety by prevention surrounding major vascular injury.

Purpose: We compared the clinical features of patients with biliary atresia (BA) associated with a bleeding tendency (BT) at the time of the diagnosis with those of patients without a bleeding tendency (NBT). Methods: The patients’ background characteristics, age in days at the first visit, Kasai portoenterostomy (KPE), and postoperative course were retrospectively analyzed. Results: Nine of the 93 BA patients (9.7%) showed a BT, including 7 with intracranial hemorrhaging (ICH), 1 with gastrointestinal bleeding, and 1 with a prothrombin time (PT) of 0%. The age at the first visit was 62 ± 12 days old for BT patients and 53 ± 27 days old for NBT patients (p = 0.4); the age at KPE was 77 ± 9 days old for BT patients and 65 ± 24 days old for NBT patients (p = 0.2); the time from the first visit to surgery was 13 ± 7 days for BT patients and 11 ± 10 days for NBT patients (p = 0.5); and the native liver survival rate was 56% for BT patients and 58% for NBT patients (p = 1), with no significant difference in any of the parameters. The neurological outcomes of survivors of ICH were favorable. Conclusions: Appropriate BT correction allowed early KPE even after ICH, resulting in native liver survival rates comparable to those of NBT patients without significant neurological complications.

<b>Introduction </b>Photodynamic therapy (PDT) is a salvage treatment for local failure after chemoradiotherapy for esophageal cancer. Salvage PDT is the treatment available for vulnerable patients with various comorbidities at risk of salvage esophagectomy. This study assessed the impact of the Charlson comorbidity index (CCI) on the outcomes of salvage PDT using talaporfin sodium (TS) for esophageal cancer. <b>Patients and methods </b>Consecutive patients with esophageal cancer who underwent salvage TS-PDT from 2016 to 2022 were included in this retrospective study. We investigated the local complete response (L-CR), progression-free survival (PFS) and overall survival (OS) and evaluated the relationship between the CCI and therapeutic efficacy. <b>Results </b>In total, 25 patients were enrolled in this study. Overall, 12 patients (48%) achieved an L-CR, and the 2-year PFS and OS rates were 24.9% and 59.4%, respectively. In a multivariate analysis, a CCI ≥1 (p=0.041) and deeper invasion (p=0.048) were found to be significant independent risk factors for not achieving an L-CR. To evaluate the efficacy associated with comorbidities, we divided the patients into the CCI=0 group (n=11) and the CCI ≥1 group (n=14). The rate of an L-CR (p=0.035) and the 2-year PFS (p=0.029) and OS (p=0.018) rates in the CCI ≥1 group were significantly lower than those in the CCI=0 group. <b>Conclusion </b>This study found that the CCI was negatively associated with the efficacy of salvage TS-PDT for esophageal cancer.

Background: Progression of chronic liver fibrosis and related increased fibrotic markers are associated with functional liver reserves or patient prognosis as well as tumor factors in hepatocellular carcinoma (HCC) patients. The aim of this study was to newly clarify the relationship between fibrotic markers and HCC malignant behaviors or its long-term postoperative prognosis by the retrospective cohort study. Methods: We examined the relationship between tumor-related factors or six liver fibrosis-associated parameters, including platelet count, hyaluronic acid (HA), Mac-2 binding protein glycosylation isomer (M2BPGi), type IV collagen 7S (T4C7), aspartate aminotransferase-to-platelet ratio index (APRI), fibrosis-4 (Fib-4) index, and clinicopathological parameters, surgical records, and postoperative prognosis in 130 HCC who underwent curative hepatectomy. Results: Histological fibrosis stage 4 as cirrhosis was in 31%. The platelet count significantly decreased in stage 4 fibrosis and correlated with grade B liver damage (P<0.01). HA levels were significantly increased in multiple HCC, stage 4 fibrosis, and grade B liver damage (P<0.01). T4C7 was significantly increased in patients with post-hepatectomy tumor recurrence compared to those without (P<0.01). Additionally, M2BPGi was significantly higher in stage 4 fibrosis and liver damage grade B, and was significantly associated with poor prognosis (P<0.05). Fib-4 index was significantly higher in patients with liver damage B (P<0.05), and T4C7 alone did not correlate with other five fibrosis markers. Stage 4 fibrosis, higher T4C7, higher M2BPGi, and increased tumor size were significantly associated with shorter cancer-free, overall, and cancer-specific survivals. Higher T4C7, non-met Milan criteria, liver damage B, blood transfusion, and curability C were independently associated with cancer-specific survivals (P<0.05). Conclusions: Type IV collagen 7S (T4C7) may reflect not only impaired liver function but also HCC malignant behaviors and patient survivals.

Objective: We examined the relation between several fibrotic markers reflecting liver parenchymal injury and conventional liver function or surgical outcomes in 67 patients with cholangiocarcinoma who underwent biliary drainage for obstructive jaundice followed by surgical resection. Material and Methods: We examined conventional clinicopathological factors, six hepatic fibrosis parameters, including platelet count, hyaluronic acid, Mac-2 binding protein glycosylation isomer (M2BPGi), type IV collagen 7S, aspartate aminotransferase-to-platelet ratio index (APRI), and FIB-4 index before hepatectomy, and surgical outcomes or long-term prognosis. Results: Obstructive jaundice was observed in 57% of the patients, a history of biliary diseases in 7.5%, and chronic hepatic injuries in 17.9%. M2BPGi was significantly higher in patients with obstructive jaundice as the primary sign (p< 0.05), the FIB-4 index was significantly correlated with patient age (p< 0.01), and serum hyaluronic acid and T4C7 levels were significantly increased in distal cholangiocarcinoma (CC). No markers were associated with the histological hepatic fibrotic index, tumor-related factors, or postoperative morbidities. Tumor relapse was observed in 37% of patients, and cancer-related death was observed in 25%. A higher FIB-4 index was significantly associated with shorter cancer-free survival (p< 0.05). Cox multivariate analysis showed that bilirubin levels, poor histological cancer differentiation, and absence of fibrotic markers were associated with cancer-free, cancer-specific overall, and overall survival. Conclusion: Although a sufficient relation exists between these markers and elastographic or histological fibrotic indexes, the clinical significance of measuring conventional fibrotic markers might no longer be necessary in future studies.

A 48-year-old woman underwent transcatheter arterial embolization (TAE) for a splenic artery aneurysm, which resulted in a partial splenic infarction in the middle lobe. Five years after TAE, a 20-mm diameter mass in the noninfarcted area of the spleen was detected on imaging, which grew to 25 mm in diameter after 6 months. MRI after gadolinium administration showed a 35 × 34 mm mass within the superior pole and 15 × 12 mm mass within the inferior pole. The patient underwent laparoscopic splenectomy and had an uneventful postoperative recovery. No evidence of recurrence was observed during the 2-year follow-up period after surgery. The mass was pathologically confirmed to be sclerosing angiomatoid nodular transformation (SANT) of the spleen. While some studies hypothesize that SANT is a response to vascular injury or trauma, to the best of our knowledge, there have been no previous reports of SANT occurring after procedures directly affecting splenic blood flow. Additionally, multifocal SANTs are reported to be very rare, accounting for only 4.7% of all reported SANTs of the spleen. We highlight a rare course of SANT of the spleen and discuss the possible relationship between blood flow abnormalities and the appearance of SANT.

Su (var) 3–9, enhancer of seste, trithorax (SET)-domain bifurcated histone lysine methyltransferase (SETDB1) plays a crucial role in maintaining intestinal stem cell homeostasis; however, its physiological function in epithelial injury is largely unknown. In this study, we investigated the role of SETDB1 in epithelial regeneration using an intestinal ischemia/reperfusion injury (IRI) mouse model. Jejunum tissues were sampled after 75 min of ischemia followed by 3, 24, and 48 h of reperfusion. Morphological evaluations were performed using light microscopy and electron microscopy, and the involvement of SETDB1 in epithelial remodeling was investigated by immunohistochemistry. Expression of SETDB1 was increased following 24 h of reperfusion and localized in not only the crypt bottom but also in the transit amplifying zone and part of the villi. Changes in cell lineage, repression of cell adhesion molecule expression, and decreased histone H3 methylation status were detected in the crypts at the same time. Electron microscopy also revealed aberrant alignment of crypt nuclei and fusion of adjacent villi. Furthermore, increased SETDB1 expression and epithelial remodeling were confirmed with loss of stem cells, suggesting SETDB1 affects epithelial cell plasticity. In addition, crypt elongation and increased numbers of Ki-67 positive cells indicated active cell proliferation after IRI; however, the expression of PCNA was decreased compared to sham mouse jejunum. These morphological changes and the aberrant expression of proliferation markers were prevented by sinefungin, a histone methyltransferase inhibitor. In summary, SETDB1 plays a crucial role in changes in the epithelial structure after IRI-induced stem cell loss.

Background: Distal pancreatectomy (DP) with lymph node (LN) dissection is the standard procedure for pancreatic ductal adenocarcinoma of the tail (Pt-PDAC). However, the optimal surgery including extent of LN dissection is still being debated. The present study investigated the incidence and prognostic impact of LN metastasis on patients suffering from Pt-PDAC. Patients and method: This multicenter, retrospective study involved 163 patients who underwent DP for resectable Pt-PDAC at 12 institutions between 2013 and 2017. The frequency of LN metastasis and the effect of LN dissection on Pt-PDAC prognosis were investigated. Results: There were high incidences of metastases to the LNs along the splenic artery in the patients with Pt-PDAC (39%). The rate of metastases in the LNs along the common hepatic, left gastric, and celiac arteries were low, and the therapeutic index for these LNs was zero. In pancreatic tail cancer located more distally, there were no metastases to the LNs along the common hepatic artery. Multivariate analysis revealed that tumor size was the only independent factor related to recurrence-free survival (HR = 2.01, 95% CI = 1.33–3.05, p = 0.001). The level of pancreas division and LN dissection along the common hepatic artery did not affect the site of tumor recurrence or recurrence-free survival. Conclusions: LN dissection along the hepatic artery for Pt-PDAC has little significance. Distal pancreatic transection may be acceptable in terms of oncological safety, but further examination of short-term outcomes and preservation of pancreatic function is required.

A 15-year-old girl with recurrent upper abdominal pain was diagnosed with congenital biliary dilatation. Abdominal enhanced computed tomography (CT) showed the anterior segmental branch of the right hepatic artery (RHA) running across the ventral aspect of the dilated common hepatic duct (CHD). Laparoscopic extrahepatic dilated biliary duct excision and Roux-en-Y hepaticojejunostomy were planned. Intraoperatively, the dilated CHD was observed to bifurcate into the ventral and dorsal ducts, between which the anterior segmental branch of the RHA crossed through the CHD. The CHD rejoined on the distal side as one duct. We transected the CHD just above the cystic duct. The patency of the ventral and dorsal sides of the bifurcated CHD was confirmed. Laparoscopic hepaticojejunostomy was performed at the distal side of the rejoined CHD, without sacrificing the anterior segmental branch of the RHA. There was no postoperative blood flow impairment in the right hepatic lobe or anastomotic stenosis.

We developed a prototype VR platform, VECTORS L&M (VLM), aiming to enhance the understanding of digestive surgery for students, interns, and young surgeons by limiting costs. Its efficacy was assessed via questionnaires before implementation in surgical education. The VLM provides nine-minute VR views of surgeries, from both 180- and 360-degree angles. It was created with L.A.B. Co., Ltd. and incorporates surgery videos from biliary malignancy patients. Following VLM development, a survey was conducted among surgeons who had experienced it. Twenty-eight participants (32% of observers) responded to the survey. A majority (81%) reported positive experiences with the VR content and showed interest in VR video production, though some reported sickness. Most respondents were experienced surgeons, and nearly all believed VR was important for medical education with a mean score of 4.14 on a scale of up to 5. VR was preferred over 3D printed models due to its application versatility. Participants expressed the desire for future VR improvements, such as increased mobility, cloud connectivity, cost reduction, and better resolution. The VLM platform, coupled with this innovative teaching approach, offers experiential learning in intraabdominal surgery, effectively enriching the knowledge of students and surgeons ahead of surgical education and training.

Background: The aim of this study was to analyze the nationwide surgical outcome of a left trisectionectomy (LT) and to identify the perioperative risk factors associated with its morbidity. Methods: Cases of LT for hepato-biliary malignancies registered at the Japanese National Clinical Database between 2013 and 2019 were retrospectively reviewed. Statistical analyses were performed to identify the perioperative risk factors associated with a morbidity of Clavien–Dindo classification (CD) ≥III. Results: Left trisectionectomy was performed on 473 and 238 cases of biliary and nonbiliary cancers, respectively. Morbidity of CD ≥III and V occurred in 45% and 5% of cases with biliary cancer, respectively, compared with 26% and 2% of cases with nonbiliary cancer, respectively. In multivariable analyses, biliary cancer was significantly associated with a morbidity of CD ≥III (odds ratio, 1.87; p =.018). In subgroup analyses for biliary cancer, classification of American Society of Anesthesiologists physical status (ASA-PS) 2, portal vein resection (PVR), and intraoperative blood loss ≥30 mL/kg were significantly associated with a morbidity of CD ≥III. Conclusions: Biliary cancer induces severe morbidity after LT. The ASA-PS classification, PVR, and intraoperative blood loss indicate severe morbidity after LT for biliary cancer.

Purpose: Uncontrollable bleeding remained problematic in anatomical hepatectomy exposing hepatic veins. Based on the inferior vena cava (IVC) anatomy, we attempted to analyze the hemodynamic and surgical effects of the combined IVC-partial clamp (PC) accompanied with the Trendelenburg position (TP). Methods: We prospectively assessed 26 consecutive patients who underwent anatomical hepatectomies exposing HV trunks between 2020 and 2023. Patients were divided into three groups: use of IVC-PC (group 1), no use of IVC-PC (group 2), and use of IVC-PC accompanied with TP (group 3). In 10 of 26 patients (38%), hepatic venous pressure was examined using transhepatic catheter insertion. Results: IVC-PC was performed in 15 patients (58%). Operating time and procedures did not significantly differ between groups. A direct hemostatic effect on hepatic veins was evaluated in 60% and 70% of patients in groups 1 and 3, respectively. Group 1 showed significantly more unstable vital status and vasopressor use (p < 0.01). Blood or fluid transfusion and urinary output were similar between groups. Group 2 had a significantly lower baseline central venous pressure (CVP), while group 3 showed a significant increase in CVP in TP. CVP under IVC-PC seemed lower than under TP; however, not significantly. Hepatic venous pressure did not significantly differ between groups. Systolic arterial blood pressure significantly decreased via IVC-PC in group 1 and to a similar extent in group 3. Heart rate significantly increased during IVC-PC (p < 0.05). Conclusion: IVC-PC combined with the TP may be an alternative procedure to control intrahepatic venous bleeding during anatomical hepatectomy exposing hepatic venous trunks.
