Background: This study aims to clarify the perioperative risk factors and short-term prognosis of central bisectionectomy (CB) for hepatocellular carcinoma (HCC). Methods: Surgical data from 142 selected patients out of 171 HCC patients who underwent anatomical CB (H458) between 2005 and 2020 were collected from 17 expert institutions in a single-arm retrospective study. Results: Morbidities recorded by the International Study Group of Liver Surgery (ISGLS) from grade BC post-hepatectomy liver failure (PHLF) and bile leakage (PHBL), or complications requiring intervention were observed in 37% of patients. A multivariate analysis showed that increased blood loss (iBL) > 1500 mL from PHLF (risk ratio [RR]: 2.79), albumin level < 4 g/dL for PHBL (RR, 2.99), involvement of segment 1, a large size > 6 cm, or compression of the hepatic venous confluence or cava by HCC for all severe complications (RR: 5.67, 3.75, 6.51, and 8.95, respectively) (p < 0.05) were significant parameters. Four patients (3%) died from PHLF. HCC recurred in 50% of 138 surviving patients. The three-year recurrence-free and overall survival rates were 48% and 81%, respectively. Conclusions: Large tumor size and surrounding tumor involvement, or compression of major vasculatures and the related iBL > 1500 mL were independent risk factors for severe morbidities in patients with HCC undergoing CB.

Purpose: We used a novel diagnostic Fourier transform (FT) algorithm of the entire extrahepatic bile duct (EHBD) measured by magnetic resonance cholangiography (MRC) to evaluate subtle deformation of bile duct lumen, indicating the malignant potential of EHBD, in patients with pancreaticobiliary maljunction (PBMJ) and in a comparative group of controls without PBMJ. Methods: From the workstation, the EHBD lumen was traced automatically and a 2D diagram cross section was measured at 0.5 mm-longitudinal intervals. The FT-based integrated power spectral density function value (FTPSDI) of the diameter or area (mm2 or mm4/Hz) and the phase value distribution entropy (PVDE) were also measured. Results: There were 16 patients with undilated PBMJ and 7 with dilated PBMJ. The control group comprised 10 patients with a normal bile duct, 20 with bile duct carcinoma (BDC), and 1 with primary sclerosing cholangitis. Both the diameter and area of the dilated bile ducts and the ducts with early- or advanced-stage BDC were significantly greater than those of the normal duct (p < 0.05). The undilated type of PBMJ tended to have a larger FTPSDI diameter than a normal bile duct, which had a smaller diameter than the dilated type of PBMJ or BDC. BDC had a significantly larger FTPSDI diameter (p < 0.05) and the cutoff value for accuracy was 168 mm2 Hz−1. Conclusion: The novel mathematical FTPSDI is a promising indicator of whether preventive EHBD resection is necessary for patients with PBMJ, which can be widely applied in the early diagnosis of other biliary diseases.

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.

Introduction: Duodenal adenocarcinoma is a rare malignancy; recently, it has been found to be accompanied by operative indications. Methods: Nine consecutive rare cases were diagnosed with duodenal carcinoma (DC), in which clinicopathological characteristics were retrospectively examined. Age was ranged over middle-aged males and females. No clinical onset with severe symptoms was observed, and the specific treatment for accompanied diseases or habits was not found. Outcomes: One case of two T1 stage DCs that underwent pancreas-sparing duodenectomy. Stage II DC was diagnosed in three cases, and stage III DC was diagnosed in four cases. Pancreaticoduodenectomy (PD) mainly occurred in seven patients, and duodenectomy was limited in two patients. All operations were safely performed, and the postoperative course showed no severe morbidity. Histological findings showed R0 resection in eight cases and R1 at the retroperitoneal dissecting part in one case. Five patients with advanced-stage DC underwent adjuvant chemotherapy; however, four patients showed tumor recurrence within 12 months. With additional strong chemotherapy, eight patients survived up to 84 months, and one died of liver metastasis at 43 months after surgery. Three representative cases of mucosal invasion with widespread pancreas-sparing duodenectomy and advanced-stage DC cases undergoing duodenectomy or PD are shown. Conclusion: In the field of upper digestive tract surgery, duodenal adenocarcinoma and various applications of surgery or adjuvant chemotherapy for long-term survival are important.

We report a case of injury of the external iliac vein caused by a stab wound. A 55-year-old man presented with a piece of wood stuck in his right abdomen. Physical examination revealed that he was in a state of shock and he was urgently transferred to our emergency department. We suspected gastrointestinal perforation and right external iliac arteriovenous injury based on the findings of CT, and decided to perform emergency surgery. Intraoperative exploration revealed that a piece of wood had penetrated the small intestine and the right external iliac vein. We controlled bleeding by compression and repaired the veins. After the operation, right external iliac vein thrombosis was observed, which resolved with anticoagulant therapy. Traumatic iliac vein injury is relatively rare, but since it is often fatal, prompt and appropriate treatment is necessary.

A 73 y.o.-male underwent the arch aortic replacement for type A acute aortic dissection. Two years after operation, the computed tomography showed the rupture of thoracic aortic aneurysm and thoracic endovascular aortic repair （TEVAR） was urgently performed. Aorto-esophageal fistula （AEF） subsequently occurred at day 5 after TEVAR. Therefore, we urgently performed esophagectomy under right thoracotomy with accompanied fistulectomy, followed by omentopexy and esophageal reconstruction using gastric conduit 12 days later. To secure AEF patients, the immediate bleeding and infectious control is required. Although urgent artificial blood vessel replacement with esophagectomy with fistulectomy of AEF is desirable, the strategy of surgical intervention depends on the patient’s organ functions or systemic status. Omentopexy is an effective option to reinforce the postoperative infectious control and, additionally, the intraoperative ICG fluorescence angiography may improve to evaluate the omental vascularity by our experience.

光線力学的療法は、切除不能胆管癌に対する補助化学療法として効果が期待できる。一方で、光線過敏症などの副作用もあり、腫瘍特異成・抗腫瘍効果が高く副作用の少ない光感受性物質の開発がのぞまれる。新規光感受性物質と期待される糖鎖連結クロリンを用いた胆道癌に対する光線力学的療法について、現在使用されているタラポルフィリンナトリウム（レザフィリン）と比較検討した。細胞を用いた実験では、殺細胞効果・アポトーシス誘導効果が高いことが分かり、糖鎖連結クロリンが新規光感受性物質として期待できるという結果を得た。
