Abstract
PURPOSE To evaluated the impact of a deep learning (DL)-based image reconstruction on multi-arterial-phase magnetic resonance imaging (MA-MRI) for small hypervascular hepatic masses in patients who underwent gadoxetic acid-enhanced liver MRI. METHODS We retrospectively enrolled 55 adult patients (aged ≥ 18 years) with small hepatic hypervascular mass (≤ 3 cm) between December 2022 and February 2023. All patients underwent MA-MRI, subsequently reconstructed with a DL-based application. Qualitative assessment with Linkert scale including motion artifact (MA), liver edge (LE), hepatic vessel clarity (HVC) and image quality (IQ) was performed. Quantitative image analysis including signal to noise ratio (SNR), contrast to noise ratio (CNR) and noise was performed. RESULTS On both arterial phases (APs), all qualitative parameters were significantly improved after DL-based image reconstruction. (LE on 1st AP, 1.22 vs 1.61; LE on 2nd AP, 1.21 vs 1.65; HVC on 1st AP, 1.24 vs 1.39; HVC on 2nd AP, 1.24 vs 1.44; IQ on 1st AP, 1.17 vs 1.45; IQ on 2nd AP, 1.17 vs 1.47, all p values < 0.05). The SNR, CNR and noise were significantly improved after DL-based image reconstruction. (SNR on AP1, 279.08 vs 176.14; SNR on AP2, 334.34 vs 199.24; CNR on AP1, 106.09 vs 64.14; CNR on AP2, 129.66 vs 73.73; noise on AP1, 1.51 vs 2.33; noise on AP2, 1.45 vs 2.28, all p values < 0.05). CONCLUSIONS Gadoxetic acid-enhanced MA-MRI with DL-based image reconstruction improved the qualitative and quantitative parameters. Despite the short acquisition time, high-quality MA-MRI is now achievable.

Abstract
BACKGROUND Currently, there is no standard adjuvant therapy for patients with resected ampulla of Vater (AoV) cancer. AIM To evaluate the effectiveness of adjuvant concurrent chemoradiotherapy (CCRT) in patients with advanced AoV cancer who underwent curative resection. METHODS This single-centered, retrospective study included 29 patients with advanced AoV cancer who underwent pancreaticoduodenectomy between 2006 and 2018. The impact of CCRT on advanced AoV cancer was analyzed. RESULTS The 1-, 3-, and 5-yr recurrence-free survival (RFS) rates for patients with advanced AoV cancer were 82.8%, 48.3%, and 40.8%, respectively, and the overall survival (OS) rates were 89.7%, 62.1%, and 51.7%, respectively. Lymphovascular invasion was found to be a significant risk factor for RFS and OS in patients with advanced AoV cancer in the univariate analysis, whereas T stage and lymph node metastasis were significantly associated with OS in the multivariate analysis. Compared to the patients who did not receive adjuvant CCRT, those who received adjuvant CCRT did not show statistically significant improvements in the RFS and OS, although they had a significantly lower average age and significantly higher platelet-to-lymphocyte ratio. CONCLUSION Adjuvant CCRT did not improve survival outcomes in patients with advanced AoV cancer. These findings contribute to existing knowledge on the effectiveness of CCRT in this patient population and provide important insights for clinical decision-making.

Abstract
BACKGROUND The histological subtype is an important prognostic factor for ampulla of Vater (AoV) cancer. This study proposes a classification system for the histological subtyping of AoV cancer based on immunohistochemical (IHC) staining and its prognostic significance. METHODS Seventy-five AoV cancers were analyzed for cytokeratin 7 (CK7), CK20, and causal-type homeobox transcription factor 2 (CDX2) expression by IHC staining. We differentiated the subtypes (INT, intestinal; PB, pancreatobiliary; MIX, mixed; NOS, not otherwise specified) into classification I: CK7/CK20, classification II: CK7/CK20 or CDX2, classification III: CK7/CDX2 and examined their associations with clinicopathological factors. RESULTS Classifications I, II, and III subtypes were INT (7, 10, and 10 cases), PB (43, 37, and 38 cases), MIX (13, 19, and 18 cases), and NOS (12, 9, and 9 cases). Significant differences in disease-free survival among the subtypes were observed in classifications II and III using CDX2; the PB and NOS subtype exhibited shorter survival time compared with INT subtype. In classification III, an association was revealed between advanced T/N stage, poor differentiation, lymphovascular invasion (LVI), the PB and NOS subtypes, and recurrence risk. In classification III, the subtypes differed significantly in T/N stage and LVI. Patients with the PB subtype had advanced T and N stages and a higher incidence of LVI. CONCLUSIONS Classification using CDX2 revealed subtypes with distinct prognostic significance. Combining CK7 and CDX2 or adding CDX2 to CK7/CK20 is useful for distinguishing subtypes, predicting disease outcomes, and impacting the clinical management of patients with AoV cancer.

Abstract
Backgrounds/Aims In 2019, the grading and staging system for neuroendocrine neoplasms (NENs) was significantly changed. In this study, we report the clinicopathological characteristics and surgical outcomes of patients with extrahepatic biliary NENs who underwent curative resection with or without adjuvant treatment. Methods We retrospectively reviewed a database of 16 patients who developed NENs, neuroendocrine carcinoma (NEC), and mixed endocrine non-endocrine neoplasms (MiNENs) after curative resection. Among them, eight patients had ampulla of Vater (AoV) tumors, and eight patients had non-AoV tumors. Results G1 and G2 were more frequently observed in the AoV group than in the non-AoV group (12.5% and 62.5%, respectively). In contrast, NEC and MiNEN were more common in the non-AoV group (50.0%). High Ki-67 index (> 20%) and perineural invasion (PNI) were more frequently observed in the non-AoV group. Advanced age (> 65 years), mitotic count > 20 per 2 mm2, and Ki-67 index > 20% were strongly correlated with patient survival (p = 0.018, 0.009, and 0.044, respectively). Advanced age (> 65 years) and mitotic count > 20 per 2 mm2 were significantly correlated with disease recurrence (p = 0.033 and 0.010, respectively). Conclusions AoV and non-AoV tumors had significant differences in the histologic grade, Ki67, and PNI. Patients with non-AoV tumors had an increased risk for survival and recurrence than those in the AoV group. For extrahepatic biliary NENs, early detection of tumors, adequate surgery, and aggressive adjuvant treatment for high-risk patients are important to achieve long-term survival and prevent disease recurrence.

Abstract
BACKGROUND Pancreatic walled-off necrosis (WON) rarely causes critical gastric necrosis and perforation, which may develop when pancreatic WON squashes against the stomach. The Atlanta 2012 guidelines were introduced for acute pancreatitis and its related clinical entities. However, there are few reported cases describing the clinical course and resolution of pancreatic WON. CASE SUMMARY We report the case of a 45-year-old man who presented to the urgent emergency department with gastric perforation caused by a severe complication of pancreatic WON on computed tomography. The patient underwent an emergency distal pancreatectomy, splenectomy, and gastric wedge resection. Postoperative findings showed re-perforation of the gastric wall at a previously resected margin. Furthermore, endoscopic examination revealed an ulcerative area with a defect in the fundus. After diagnostic endoscopy, endoscopic vacuum-assisted closure was performed, and continuous suction was transferred over all tissues in contact with the sponge surface. The patient recovered without any further complications and was discharged in good condition at postoperative week 8. No recurrence occurred during the 6-mo follow-up period. CONCLUSION When managing a patient with serious gastric perforation complicated by pancreatic WON, a multidisciplinary treatment approach should be considered.

Abstract
Backgrounds/Aims Postoperative delirium (POD) is a common complication that increases mortality and morbidity in older patients. This study aimed to evaluate the clinical significance of post-cholecystectomy delirium in older patients. Methods This retrospective study included 201 patients aged > 75 years who underwent cholecystectomy for acute or chronic cholecystitis between January 2016 and December 2019. Patients were divided into the POD (n = 21) and non-POD (n = 180) groups, and their demographic features and clinical results were compared. Results The mean patient age was 78.88 years; the female/male ratio was 44.8%/55.2%. Laparoscopic surgery was performed in 93.5% of patients. The univariate analysis showed that lower body mass index (BMI), immobilized admission status, neuropsychiatric disease history, preoperative intervention (percutaneous drainage), high C-reactive protein, hypoalbuminemia, neutrophilia, hypo-/hyperkalemia, and longer operative time were more frequently observed in the POD group. The multivariate analysis showed that lower BMI (odds ratio [OR], 2.796; p = 0.024), neuropsychiatric disease history (OR, 3.019; p = 0.049), hyperkalemia (OR, 5.972; p = 0.007), and longer operative time (OR, 1.011; p = 0.013) were significant risk factors for POD. Conclusions POD was associated with inflammation degree, general condition, poor nutritional status, electrolyte imbalance, and stressful conditions. Recognizing risk factors requiring multidisciplinary team approaches is important to prevent and treat POD.

Abstract
Tumor could directly invade or is adherent to other organs, but superior mesentery vein (SMV) and duodenum invasion are very rare. A 62-year-old woman was diagnosed with abdominal pain for several months. Multiple erythematous brownish skin patches and palpable mass were found at epigastric area. Computed tomography imaging showed focal wall thickening at the transverse colon that invaded to the rectus muscle and anterior abdominal wall. On exploration, we identified tumor invaded or was adherent to the duodenum and superior mesenteric vein and performed en-bloc resection. After surgery, the patient received chemotherapy and was followed up without any recurrence for 16 months. Adhesion and invasion of tumor to surrounding organs can be unexpectedly found during surgery. In our case, we found duodenum and SMV invasion and achieved R0 resection by SMV and duodenum resection, which could improve the patient's prognosis.

Abstract
Inguinal hernia repair using prosthetic mesh is used as a standard treatment in most countries and considered superior to primary suture repair. Although prosthetic mesh has greatly reduced the risk of recurrence, the risk of mesh infection remains. A 71-year-old man was diagnosed with symptomatic bilateral inguinal hernias. He underwent successful laparoscopic transabdominal preperitoneal (TAPP) repair and was discharged the same day. After 3 days, he was diagnosed with small bowel perforation, and underwent emergency surgery. We found perforation of the distal ileum caused by the fecal impaction and severe intra-abdominal contamination. We performed subtotal colectomy and ileosigmoid anastomosis, but did not remove the prosthetic mesh because the previous TAPP site was intact. The patient recovered well post-operatively. Therefore, contaminated or dirty surgery immediately after the hernia mesh surgery could be a feasible treatment.

Abstract
Purpose Although there are many studies on prealbumin in individual diseases such as malignant or inflammatory diseases, there are few comparative studies. This study aimed to compare the clinical differences between prealbumin levels in cholecystitis and pancreaticobiliary malignancies and investigate the clinical impact of low prealbumin levels in pancreaticobiliary malignancies. Methods From June 2021 to September 2021, 61 patients who had undergone surgery for various pancreaticobiliary diseases were enrolled in this study, and their clinicopathological data were retrospectively analyzed. Results Many elderly patients with malignant diseases had poor American Society of Anesthesiologists (ASA) scores, significantly lower albumin and prealbumin levels, and higher systemic immune inflammation indices. The low prealbumin group was older; had poorer ASA scores; and had significantly lower body mass index and hemoglobin and albumin levels and higher systemic immune inflammation indices than the normal prealbumin group. In malignant diseases, the low prealbumin group had significantly lower body mass index and hemoglobin levels and a tendency toward more advanced disease (lymph node and distant metastasis). Conclusion Preoperative low prealbumin levels had an area under the receiver operator characteristic curve of 0.69, suggesting that it may be useful for predicting pancreaticobiliary malignancies. Prealbumin levels were lower in malignant diseases, possibly related to poor nutritional status and systemic immune inflammation. Low prealbumin levels may predict the risk of more advanced disease.

Abstract
Backgrounds/Aims Despite its limited benefits, operative site drainage after elective hepatectomy is routinely used. This study aimed to investigate the safety and effectiveness of left lateral sectionectomy without operative site drainage. Methods This study retrospectively collected data from 31 patients who underwent elective left lateral sectionectomy between January 2017 and June 2020. Based on whether operative site drainage was used, the patients were divided into two groups: drainage and non-drainage of the operative site and a comparative analysis was conducted. Results A total of 31 patients underwent left lateral sectionectomy during the study period. Of these, 22 patients were diagnosed with hepatocellular carcinoma; three, with intrahepatic cholangiocarcinoma; three, with liver metastasis; and three, with benign liver disease. Ten patients underwent laparoscopy. No significant differences were observed between the open and laparoscopic surgery groups. In the univariate analysis, there were no significant differences in the pre-, intra-, and postoperative clinicopathological factors between the non-drainage and drainage groups. The hospitalization period in the non-drainage group was significantly shorter than in the drainage group (8.44 days vs. 5.87 days, p < 0.05). In the operative site drainage non-use group, there were no cases of intraperitoneal fluid collection requiring additional procedures. Conclusions Routine use of surgical drainage for left lateral sectionectomy of the liver to prevent intraperitoneal fluid collection is unnecessary.

Abstract
BACKGROUND Combined tumors comprising large-cell neuroendocrine carcinoma and hepatocellular carcinoma have been rarely reported in the literature.
CASE SUMMARY We report a case of a 73-year-old woman with chronic hepatitis B suspected to have a malignant hepatic mass (segment 3; size, 4.5 cm) and lymph node metastasis based on computed tomography and magnetic resonance imaging. Despite being Child-Pugh class A, esophageal varices were present. She underwent left lateral sectionectomy and lymph node dissection. Pathological examination revealed a collision tumor consisting of large-cell neuroendocrine (90%) and hepatocellular (10%) carcinomas. The combined carcinoma had metastasized to one of the three lymph nodes excised. The patient recovered without any postoperative complications and was discharged in good condition on postoperative day 13. Adjuvant chemotherapy was not performed. No recurrence occurred during a follow-up period of 24 mo.
CONCLUSION To improve the therapeutic management of combined tumors in the liver, it is necessary to discuss each clinical experience and consider an appropriate method for the preoperative diagnosis and treatment.

Abstract
PURPOSE To investigate the clinical significance of enhancing mural nodules ≥ 5 mm by comparing the diagnostic performance of high-risk stigmata for diagnosing the malignant IPMN between the international consensus guideline (ICG) 2012 and 2017 in pancreatic magnetic resonance image (MRI). MATERIALS AND METHODS In this retrospective study, we reviewed preoperative pancreatic MRI with surgically confirmed IPMNs between May 2009 and April 2021. High-risk stigmata, defined by ICG 2012 and ICG 2017, associated with malignant IPMN were evaluated using logistic regression analysis. We calculated and compared the sensitivity and specificity of ICG 2012 and ICG 2017 for diagnosing malignant IPMNs. Receiver-operating characteristic (ROC) curves were used to compare ICG 2012 to ICG 2017. RESULTS A total of 73 patients (43 men and 30 women; mean age, 69 years; standard deviation, 8 years) with 34 malignant IPMNs and 39 benign IPMNs were included. Among high-risk stigmata, enhancing mural nodule ≥ 5 mm, and MPD diameter ≥ 10 mm were the significant predictor of malignant IPMN, in multivariate logistic regression (P < 0.001 for all). For the diagnosis of malignant IPMN, the specificity of ICG 2017 for enhancing mural nodules ≥ 5 mm as the high-risk stigmata was significantly higher than that of ICG 2012 (87.2% vs. 64.1%, P = 0.008). However, there was no significant difference in sensitivity between the two guidelines (94.1% vs. 97.1%, P = 1.0). The comparison of the ROC curves showed that the diagnostic performance of ICG 2017 for malignant IPMNs (AUC, 0.91) significantly improved when compared to that of ICG 2012 (AUC, 0.81) (P = 0.01). CONCLUSION When applying enhancing mural nodule ≥ 5 mm as a high-risk stigmata, ICG 2017 provided a significantly higher specificity than ICG 2012 without a reduction in sensitivity.

Abstract
Bacterial infection represents a turning point in the natural history of cirrhosis, causing the development of acute-on-chronic liver failure. It significantly affects the outcome of patients listed for liver transplantation. We report the case of a 57-year-old man who had been regularly treated for hepatitis B virus, alcoholic liver cirrhosis, and hepatic failure. The patient was hospitalized again due to variceal bleeding and hepatic coma. He visited the emergency room with painful anal swelling, dysuria, icteric sclera, and serious abdominal distension. The painful anal swelling and necrosis progressed; thus, he was diagnosed with Fournier’s gangrene. Enterococcus faecium and Candida albicans were detected in the blood. Gangrene wound debris was studied extensively. Despite appropriate antibiotic treatment, vancomycin-resistant enterococcus and C. albicans were continuously present in the blood. Wide debridement of the wound and T-colostomy were performed. After this, norepinephrine and vasopressin were used to maintain stable vital signs. It was difficult to establish a liver transplant operation. Despite repeated bleeding, bacterial infections improved with additional antibiotics. Finally, selected deceased donor liver transplantation in controlled Fournier’s gangrene was successfully performed. Controlled infections may be allowed in transplantation surgery.

Abstract
Purpose The number of infrapopliteal runoff vessels seems to be one of the factors influencing arterial patency in patients who had undergone superficial femoral artery (SFA) angioplasty with stenting. However, the effectiveness of infrapopliteal runoff vessels in predicting patency during SFA angioplasty remains unclear. This study aimed to determine whether the number and quality of infrapopliteal runoff vessels affect the primary patency after SFA angioplasty with stenting in patients with claudication. Methods Materials and This study reviewed a retrospective database of patients with claudication who underwent SFA angioplasty with stenting between March 2011 and December 2016. The preoperative computed tomography findings of all patients were reviewed to assess infrapopliteal runoff vessels. The Trans-Atlantic Inter-Society (TASC) II classification and modified Society for Vascular Surgery (SVS) runoff score were used for subsequent analysis. Kaplan–Meier survival curves were constructed, and Fisher’s exact and chi-square tests were used for data analysis. Results A total of 153 limbs of 122 patients (88.2% male, mean age: 69.1 years) underwent SFA angioplasty with stenting. The overall primary patency rates of TASC II A/B and C/D cases were 77.1% and 31.2%, respectively, at 36 months (P<0.001). The primary patency rates at 36 months using the modified SVS runoff scoring system were 64.6% and 49.8% for the good-to-compromised (≤9 points) and poor (≥10 points) runoff groups, respectively (P=0.011). Conclusion The modified SVS runoff scoring system is effective in predicting primary patency after SFA angioplasty with stenting in patients treated for claudication.
