Abstract
Hypoxia may promote tumor progression, and hypoxically altered noncoding RNA (ncRNA) expression may play a role in metastasis. Canine oral melanoma (COM) frequently metastasizes, and ncRNA expression under hypoxia may be clinically significant. We aimed to elucidate ncRNA fragments whose expression is altered by hypoxia in COM-derived primary KMeC and metastatic LMeC cell lines using next-generation sequencing to validate these results in qRT-PCR, and then compare expression between metastatic and non-metastatic COM. The NGS analysis and subsequent qRT-PCR validation were performed using hypoxic and normoxic KMeC and LMeC cells, and clinical samples [tumor tissue, plasma, and plasma-derived extracellular vesicles] obtained from dogs with metastatic or non-metastatic melanoma were analyzed with qRT-PCR. Y RNA was significantly decreased in metastatic LMeC cells versus primary KMeC cells in hypoxic and normoxic conditions. The expression of Y RNA was decreased in dogs with metastatic melanoma versus those with non-metastatic melanoma for all clinical sample types, reflecting the pattern found with hypoxia. Receiver operating characteristic analysis demonstrated that Y RNA level is a promising biomarker for discriminating metastatic from non-metastatic melanoma in plasma [area under the curve (AUC) = 0.993, p < 0.0001] and plasma-derived extracellular vesicles (AUC = 0.981, p = 0.0002). Overall, Y RNA may be more resistant to hypoxic stress in the metastatic than the non-metastatic state for COM. However, further investigation is required to elucidate the biological functions of Y RNA under hypoxic conditions.

Abstract
Urothelial carcinoma (UC) is the most common malignancy of the urinary tract in dogs and has aggressive behaviour. Although human epidermal growth factor receptor 2 (HER2) is a known therapeutic target with evidence in canine UC, the efficacy of anti-HER2 antibody drugs remains unknown. This study aimed to investigate the effects of anti-HER2 antibody drugs including trastuzumab and trastuzumab emtansine (T-DM1) on canine UC cell lines in vitro and in vivo. Four canine UC cell lines (Nene, TCCUB, Love, and Sora) were used. In western blotting, HER2 protein expression was observed in all the cell lines. Although both trastuzumab and T-DM1 showed dose-dependent growth inhibitory activity in the cell lines, T-DM1 showed much stronger activity than that of trastuzumab. In flow cytometry analyses with the canine UC cell line (Sora), T-DM1 but not trastuzumab significantly increased the percentages of early and late apoptotic cells in annexin V apoptotic assays and the sub-G1 phase fraction in cell cycle analyses. For the in vivo experiment, the canine UC cells (Sora) were subcutaneously injected into nude mice. Four days after inoculation, trastuzumab, T-DM1, or vehicle was administered intraperitoneally once a week for three times. Tumour volumes were significantly smaller in the T-DM1 group compared to the trastuzumab and vehicle control groups. These findings indicate that T-DM1 exerts a stronger antitumour effect than that of trastuzumab on canine UC cells in vitro and in vivo, possibly by inducing apoptosis due to DM1.

Abstract
Canine oral melanoma (COM) is a common and highly aggressive disease with the potential to model human melanomas. Dysregulated microRNAs represent an interesting line of research for COM because they are implicated in tumor progression. One example is miR-450b, which has been investigated for its molecular mechanisms and biological functions in multiple human cancers, but not human or canine melanoma. Here, we aimed to investigate miR-450b as a potential diagnostic biomarker of COM and its functional roles in metastatic and non-metastatic forms of the disease. We investigated the expression of miR-450b and its target mRNA genes in clinical (tumor tissue and plasma) samples and metastatic and primary-tumor cell lines. Knockdown and overexpression experiments were performed to determine the influence of miR-450b on cell proliferation, migration, colony formation, and apoptosis. miR-450b was significantly upregulated in COM and differentiated between metastatic and non-metastatic tumors, and its potential as a biomarker of metastatic and non-metastatic COM was further confirmed in ROC analysis. miR-450b knockdown promoted cell proliferation, migration, and clonogenicity and inhibited apoptosis, whereas its overexpression yielded the reverse pattern. miR-450b directly binds 3' UTR of PAX9 mRNA and modulates its function leading to BMP4 downregulation and MMP9 upregulation at the transcript level. Furthermore, we surmised that miR-450b activates the Wnt signaling pathway based on gene ontology and enrichment analyses. We concluded that miR-450b has the potential as a diagnostic biomarker and could be a target candidate for COM treatment.

Abstract
Cyclooxgenase-2 (COX-2) is associated with inflammatory microenvironment and tumour progression. COX-2 expression was reported in canine tumours, and anti-COX treatment showed therapeutic effects in selected tumour types. Currently, direct comparisons between different tumour types or reports were impossible due to varying evaluation protocols. Additionally, COX-2 expression in relatively uncommon tumours were yet to be evaluated. Here, we analysed COX-2 expression across various tumour types in dogs in a consistent protocol, aiming to revisit accumulated evidence in the field and report novel candidate tumours for anti-COX therapy. COX-2 expression in 32 histological types of tumours, which consisted of 347 samples in total, was investigated using immunohistochemistry followed by the Belshaw's method scoring (range: 0-12). More than the half of the samples expressed COX-2 in mast cell tumours, transitional cell carcinoma in the urinary tract, squamous cell carcinoma, liposarcoma, and melanoma, with COX-2 median scores ranging from 1-8. On the other hand, <20% tissues expressed COX-2 in the half of tumour types investigated. Overall COX-2 positive rate was 27%. In conclusion, the results confirmed COX-2 expression in the well-known COX-2-expresing tumour types and suggested novel candidate tumours for anti-COX-2 therapy. At the same time, overall COX-2 expression was low, and inter- and intra-histology heterogeneity was apparent. This study will provide a foundation reference for future research in canine tumours.

Abstract
BACKGROUND Duodenal duplication cysts (DDC) are rare duplications of the alimentary tract. Their treatment depends on their size and location. A radical treatment is total resection, if possible. However, partial excision, puncture, and marsupialization can be selected to prevent surgical injury to the pancreaticobiliary tract despite the risk of recurrence. There are some reports of pancreaticoduodenectomy for DDC because of the risk of recurrent symptoms and malignancy. However, this is considered excessively invasive for DDC, particularly in pediatric cases, because of its extremely low rate of malignancy and high morbidity and mortality rates. We encountered a case of DDC with a congenital duodenal position anomaly occurring in the second part of the duodenum. Taking advantage of the congenital duodenal position anomaly, the DDC was completely resected without injuring the pancreaticobiliary duct. CASE PRESENTATION A 6-year-old boy was diagnosed with a duodenal duplication cyst with obstruction. There was a congenital duodenal position anomaly. The distal second part of the duodenum was the dorsal side of the proximal second part of the duodenum and ascended upward from the proximal second part of the duodenum. The third and fourth parts of the duodenum ran downward to the left and posterior parts of the portal vein, forming the ligament of Treitz. Complete laparoscopic resection of the duodenal duplication cyst and the second to fourth parts of the duodenum, and duodenojejunostomy with retrocolic reconstruction was performed because the duodenum was easily mobilized to the ligament of Treitz owing to the duodenal position anomaly. The duodenojejunostomy with retrocolic reconstruction achieved a more physiologically normal appearance compared to what would have been achieved with a Roux-en-Y reconstruction. The patient was discharged on postoperative day 12 without any complications. CONCLUSIONS The procedure used in this case might not be easily applied in all laparoscopy cases. However, it could be an option for duodenal duplication cysts with congenital duodenal position anomalies.

Abstract
PURPOSE Sandifer syndrome (SS), which combines gastroesophageal reflux (GER) and a neurological or psychiatric disorder, is an uncommon condition that often takes a long time to diagnosis. We aimed to systematically review available papers regarding SS. METHODS After presenting our two cases of SS, we systematically reviewed articles published in MEDILINE/PubMed, Cochrane Library, and Web of Science. RESULTS The meta-analysis included 54 reported cases and 2 of our own cases. Our results showed that all cases achieved symptom improvement with appropriate treatment for GER. Notably, 19 of the 56 cases exhibited anatomical anomalies, such as hiatal hernia and malrotation. Significantly more patients with than without anatomical anomalies required surgery (p < 0.001). However, 23 of the 29 patients without anatomical anomalies (79%) achieved symptom improvement without surgery. Patients who did not undergo surgery had a median (interquartile range) duration to symptom resolution of 1 (1-1) month. CONCLUSION The primary care providers should keep SS in the differential diagnosis of patients presenting with abnormal posturing and no apparent neuromuscular disorders. Fundoplication may be effective especially for patients with anatomical anomalies or those whose symptoms do not improve after more than 1 month with nonsurgical treatment.

Abstract
Despite improving the survival after repair of esophageal atresia (EA), the morbidity of EA repair remains high. Specifically, tracheomalacia (TM) is one of the most frequent complications of EA repair. Continuous positive airway pressure is generally applied for the treatment of TM. However, surgical intervention is required against an apparent life-threatening event or inability to perform extubation for a long period. According to our review, most cases of TM showed symptom improvement after aortopexy. The ratio of the trachea's lateral and anterior-posterior diameter at the brachiocephalic artery crossing the trachea, which reflects the compression of the trachea by the brachiocephalic artery, is a good indicator of aortopexy. Our finding suggests that most TM cases associated with EA may not be caused by tracheal fragility alone, but may involve blood vessel compression. Posterior tracheopexy (PT) is also an effective treatment for TM. Recently, open or thoracoscopic PT was able to be performed simultaneously with EA repair. In many cases, aortopexy or PT is a safe and effective surgical treatment for TM with EA. Other surgical procedures, such as external stenting, should be considered for patients with diffuse-type TM for whom aortopexy and PT appear relatively ineffective.

Abstract
Background: Data on the outcomes of laparoscopic fundoplication (LF) in patients with ventriculoperitoneal (VP) shunts are limited. Materials and Methods: We retrospectively evaluated the demographic characteristics and outcomes of patients who underwent LF at our institutions between 2014 and 2022. Then, we systematically reviewed articles in MEDILINE/PubMed, Cochrane Library, and Web of Science. Results: There was no significant difference in terms of the outcomes between patients with VP shunt (n = 10) and those without (n = 96) at our institutions. None of the patients presented with shunt trouble after LF. The meta-analysis included four retrospective studies and our institutional data. In total, 605 patients (55 with VP shunt) underwent LF. Furthermore, 2 (3.6%) of 55 patients (1 with infection and 1 with occlusion) had shunt troubles. The conversion and complication rates, operative time, and length of hospital stay did not significantly differ between patients with VP shunt and those without. Conclusions: LF can be safely performed on children with VP shunts and is associated with a low risk of shunt troubles. The Clinical Trial Registration number is 2022-387.

Abstract
BACKGROUND This study aimed to develop a postnatal treatment strategy for infants with prenatally diagnosed congenital biliary dilatation. METHODS We performed a retrospective study of patients with prenatal diagnosed congenital biliary dilatation (CBD), aged <1 year who underwent surgery at our hospital between 2013 and 2023. We classified the patients into two groups, the "early group," consisting of patients who could not wait for growth, and required early surgery, and the "scheduled group," consisting of patients who were asymptomatic and could undergo scheduled surgery, and compared them. The parameters for early surgical prediction were AST, ALT, TB, DB, and CRP levels at birth, 1 week, 2 weeks, 1 month, 2 months, and 3 months after birth, and immediately before surgery, as well as the cyst diameter, presence of intrahepatic bile duct dilation, and presence of debris in the common bile duct. RESULTS During the study period, 15 patients were diagnosed prenatally. The cyst diameter was significantly larger at all points in the early group. Patients with a cyst diameter of >30 mm at birth, intrahepatic bile duct dilatation at birth, and postnatal enlargement of the common bile duct to >30 mm are more likely to develop symptoms early. Blood biochemistry tests showed no significant differences between the two groups. CONCLUSIONS Patients with a cyst diameter >30 mm in the early postnatal period require careful postnatal management and parents should be counseled regarding the high likelihood of their child needing surgery within the first 3 months of life. LEVEL OF EVIDENCE Level IV.

Abstract
miR-301a is one of numerous dysregulated microRNAs (miRNAs) in canine oral melanoma (COM), one of which is miR-301a (upregulated). Its biological role has been described in various human cancer types, including malignant melanoma, but not in COM. Accordingly, in this study, we investigated miR-301a expression in COM in greater detail to ascertain whether it could serve as a diagnostic biomarker, elucidate its functional roles in this cancer, and predict the possible pathways by which it exerts its effects. Relative expression of miR-301a was investigated in clinical oral tissue and plasma samples and COM cell (KMeC and LMeC) lines using qRT-PCR. Knockdown of miR-301a was also validated for KMeC and LMeC cells using qRT-PCR. We performed CCK-8 assays to assess cell proliferation, monolayer wound-healing, and transwell migration assays to assess cell migration, a colony-formation assay to assess clonogenicity, a TUNEL assay and flow cytometry to assess apoptosis-related effects, and gene enrichment analyses to predict possible related pathways. miR-301a was markedly upregulated in COM oral tissue and plasma clinically, suggesting its potential as a diagnostic biomarker for COM diagnosis. In vitro assays demonstrated that miR-301 significantly inhibited apoptosis in COM cells while promoting cell migration, proliferation, and clonogenicity. We also predicted that miR-301 exerts cancer-promoting effects through the Wnt signalling pathway for COM. Our findings suggest that miR-301a is a COM oncomiR that regulates several oncogenic phenotypes with the potential to be a diagnostic biomarker.

Abstract
INTRODUCTION We analyzed the association between postoperative weight loss (WL), preoperative body mass index (BMI), and prognosis in patients with lung cancer who underwent lobectomy using minimally invasive approaches. METHODS Weight change in 325 patients who underwent radical lobectomy for non-small cell lung cancer was assessed at 3, 6, and 12 months postoperatively and compared to preoperative weight. Patients were divided into three groups according to their preoperative BMI interquartile range: low BMI ≤20.3 kg/m2 , middle BMI 20.4-24.4 kg/m2 , and high BMI ≥24.5 kg/m2 . Postoperative WL ≥5% was evaluated with reference to frailty. RESULTS There were no significant differences in pathological findings, postoperative complications, or postoperative hospital stay among the three groups. Thirty all-cause deaths and 39 cancer recurrences occurred. Within the first year after surgery, WL of any grade was observed in 229 patients (70.5%) and WL ≥5% in 86 patients (26.5%). Postoperative WL of any grade within 1 year after surgery was not associated with OS and RFS (both p > .05). However, WL ≥5% within 1 year after surgery was associated with worse OS and RFS (p = .007 and .006, respectively). WL ≥5% within 1 year after surgery was more common in the low BMI group (p = .045). There was no difference in OS and RFS among the BMI groups in patients with WL ≥5% and those without WL ≥5% (all p > .05). CONCLUSION WL ≥5% was associated with poor prognosis after lobectomy via minimally invasive approaches. Weighing is a useful prognostic marker that can be easily self-checked.

Abstract
We previously reported that the inhibition of stearoyl-CoA desaturase 1 (SCD1) enhances the antitumor function of CD8+ T cells indirectly via restoring production of DC recruiting chemokines by cancer cells and subsequent induction of antitumor CD8+ T cells. In this study, we investigated the molecular mechanism of direct enhancing effects of SCD1 inhibitors on CD8+ T cells. In vitro treatment of CD8+ T cells with SCD1 inhibitors enhanced IFN-γ production and cytotoxic activity of T cells along with decreased oleic acid and esterified cholesterol, which is generated by cholesterol esterase, acetyl-CoA acetyltransferase 1 (ACAT1), in CD8+ T cells. The addition of oleic acid or cholesteryl oleate reversed the enhanced functions of CD8+ T cells treated with SCD1 inhibitors. Systemic administration of SCD1 inhibitor to MCA205 tumor-bearing mice enhanced IFN-γ production of tumor-infiltrating CD8+ T cells, in which oleic acid and esterified cholesterol, but not cholesterol, were decreased. These results indicated that SCD1 suppressed effector functions of CD8+ T cells through the increased esterified cholesterol in an ACAT1-dependent manner, and SCD1 inhibition enhanced T cell activity directly through decreased esterified cholesterol. Finally, SCD1 inhibitors or ACAT1 inhibitors synergistically enhanced the antitumor effects of anti-PD-1 antibody therapy or CAR-T cell therapy in mouse tumor models. Therefore, the SCD1-ACAT1 axis is regulating effector functions of CD8+ T cells, and SCD1 inhibitors, and ACAT1 inhibitors are attractive drugs for cancer immunotherapy.

Abstract
Introduction: This study aimed to investigate the efficacy and safety of robot-assisted radical cystectomy (RARC) in older patients with bladder cancer (BCa).Material and methods: We reviewed the clinical and pathological records of 110 patients with BCa who underwent RARC at Gifu University Hospital between February 2019 and January 2023. Older patients were defined as those with BCa aged ≥ 75 years. The enrolled patients were divided into two groups: those aged < 75 years (Group I) and those aged ≥ 75 years (Group II). Oncological outcomes, including overall survival (OS) and recurrence-free survival (RFS), were the primary endpoints of the study; the secondary endpoints were the surgical and pathological outcomes.Results: A shorter console time, less blood loss, and reduced time to postoperative fluid and food intake in Group II may be attributed to the fact that more patients opted for ureterocutaneostomy in Group II than in Group I. In all patients, the three-year OS and RFS rates were 84.7% and 88.5%, respectively. There were no significant differences in OS or RFS between the two groups. (p = .403, p = .963, respectively).Conclusions: RARC appears to be a safe and useful treatment option for older patients with BCa.

Abstract
PURPOSE This study aimed to evaluate the learning curve of thoracoscopic repair of tracheoesophageal fistula (TEF) by a single surgeon using a cumulative sum (CUSUM) analysis. METHODS Prospective clinical data of consecutive Gross type-C TEF repairs performed by a pediatric surgeon from 2010 to 2020 were recorded. CUSUM charts for anastomosis and operating times were generated. The learning curves were compared with the effect of accumulation based on case experience. RESULTS For 33 consecutive cases, the mean operative and anastomosis times were 139 ± 39 min and 3137 ± 1110 s, respectively. Significant transitions beyond the learning phase for total operating and anastomosis times were observed at cases 13 and 17. Both the total operating time and anastomosis time were significantly faster in the proficiency improvement phase than in the initial learning phase. Postoperative complications significantly decreased after the initial anastomosis learning phase but not after the initial total operating learning phase. CONCLUSIONS Thoracoscopic repair of TEF is considered safe and feasible after 13 cases, where the surgeon can improve their proficiency with the total operation procedure, and 17 cases, which will enable the surgeon to achieve proficiency in anastomosis. Postoperative complications significantly decreased after gaining familiarity with the anastomosis procedure through the learning phase.

Abstract
BACKGROUND Gastrocutaneous fistulas are a rare complication of enterocutaneous fistulas and can be caused by intestinal injury, infection, and anastomotic leakage. They are typically treated conservatively or endoscopically; however, for large or difficult-to-treat gastrocutaneous fistulas, surgical intervention is required. Herein, we present a case of a huge gastrocutaneous fistula that was successfully treated with a two-stage surgery performed using open abdomen management. CASE PRESENTATION A 61-year-old man with a perforated gastric ulcer underwent omental filling as an emergency surgery. Post-operative leakage led the development of a 10-cm gastrocutaneous fistula. He was transferred to our hospital for the treatment of gastrocutaneous fistula. Furthermore, nutritional therapy was administered for dehydration, electrolyte abnormalities, metabolic acidosis, and acute kidney injury due to the high-output nature of the fistula. Moreover, owing to the intraperitoneal severe adhesion and poor nutritional status, two-stage surgery was planned. In the first stage, extensive dissection of the adhesions, distal gastrectomy reconstruction with Roux-en-Y anastomosis, and jejunostomy were performed. Furthermore, open abdomen management was conducted to check for the presence of unexpected complications due to extensive dissection of the adhesion and anastomotic leakage. Subsequently, in the second stage of the surgery, abdominal closure was performed on the 9th day after gastrectomy. CONCLUSION Open abdomen management may be effective for huge gastrocutaneous fistulas with extensive adhesions that require surgical intervention.

Abstract
BACKGROUND Preoperative management of Hirschsprung's disease (HD) is currently being conducted with the goal of performing single-stage radical surgery without ileostomy. METHODS We retrospectively reviewed HD cases between 2013 and 2022, as well as their outcomes related to preoperative management. RESULTS Thirty-nine patients with HD were included in this study, including short-segment HD (30 cases), long-segment HD (4 cases), and total colonic aganglionosis (5 cases). Among these 39 patients, 95% (37 of 39 patients) underwent single-stage radical surgery after management with glycerin enema use (n = 13), irrigation with tube insertion each time irrigation was performed (n = 13), and irrigation using a tube placed in the bowel (n = 11). CONCLUSIONS Preoperative management of patients with HD allowed for single-stage surgery of long-segment HD and total colonic aganglionosis. Cases that could be managed without performing an emergency enterostomy during the neonatal period were managed with irrigation until radical surgery was performed.

Abstract
Mucosal melanoma metastasizes at an early stage of the disease in human and dog. We revealed that overexpression of podoplanin in tumor invasion fronts (IF) was related to poor prognosis of dogs with mucosal melanoma. Moreover, podoplanin expressed in canine mucosal melanoma cells promotes proliferation and aggressive amoeboid invasion by activating Rho-associated kinase (ROCK)-myosin light chain 2 (MLC2) signaling. PDPN-ROCK-MLC2 signaling plays a role in cell-cycle arrest and cellular senescence escape as a mechanism for regulating proliferation. Podoplanin induces amoeboid invasion in the IFs of mouse xenografted tumor tissues, similar to canine mucosal melanoma clinical samples. We further identified that podoplanin expression was related to poor prognosis of human patients with mucosal melanoma, and human mucosal melanoma with podoplanin-high expression enriched gene signatures related to amoeboid invasion, similar to canine mucosal melanoma. Overall, we propose that podoplanin promotes canine and human mucosal melanoma metastasis by inducing aggressive amoeboid invasion and naturally occurring canine mucosal melanoma can be a novel research model for podoplanin expressing human mucosal melanoma. IMPLICATIONS Podoplanin could be a new therapeutic target to restrict the metastatic dissemination of canine and human mucosal melanoma.

Abstract
The Clostridia is a dominant bacterial class in the guts of various animals and are considered to nutritionally contribute to the animal host. Here, we discovered clostridial endosymbionts of cellulolytic protists in termite guts, which have never been reported with evidence. We obtained (near-)complete genome sequences of three endosymbiotic Clostridia, each associated with a different parabasalid protist species with various infection rates: Trichonympha agilis, Pseudotrichonympha grassii, and Devescovina sp. All these protists are previously known to harbor permanently-associated, mutualistic Endomicrobia or Bacteroidales that supplement nitrogenous compounds. The genomes of the endosymbiotic Clostridia were small in size (1.0-1.3 Mbp) and exhibited signatures of an obligately-intracellular parasite, such as an extremely limited capability to synthesize amino acids, cofactors, and nucleotides and a disrupted glycolytic pathway with no known net ATP-generating system. Instead, the genomes encoded ATP/ADP translocase and, interestingly, regulatory proteins that are unique to eukaryotes in general and are possibly used to interfere with host cellular processes. These three genomes formed a clade with metagenome-assembled genomes (MAGs) derived from the guts of other animals, including human and ruminants, and the MAGs shared the characteristics of parasites. Gene flux analysis suggested that the acquisition of the ATP/ADP translocase gene in a common ancestor was probably key to the emergence of this parasitic clade. Taken together, we provide novel insights into the multilayered symbiotic system in the termite gut by adding the presence of parasitism and present an example of the emergence of putative energy parasites from a dominant gut bacterial clade.

Abstract
Robot-assisted radical prostatectomy (RARP) has become one of the standard radical treatments for prostate cancer (PCa). A retrospective single-center cohort study was conducted on patients with PCa who underwent RARP at Gifu University Hospital between September 2017 and September 2022. In this study, patients were classified into three groups based on the National Comprehensive Cancer Network risk classification: low/intermediate-risk, high-risk, and very-high-risk groups. Patients with high- and very-high-risk PCa who were registered in the study received neoadjuvant chemohormonal therapy prior to RARP. Biochemical recurrence-free survival (BRFS) after RARP in patients with PCa was the primary endpoint of this study. The secondary endpoint was the relationship between biochemical recurrence (BCR) and clinical covariates. We enrolled 230 patients with PCa in our study, with a median follow-up of 17.0 months. When the time of follow-up was over, 19 patients (8.3%) had BCR, and the 2 years BRFS rate for the enrolled patients was 90.9%. Although there was no significant difference in BRFS between the low- and intermediate-risk group and the high/very-high-risk group, the 2 years BRFS rate was 100% in the high-risk group and 68.3% in the very-high-risk group (P = 0.0029). Multivariate analysis showed that positive surgical margins were a significant predictor of BCR in patients with PCa treated with RARP. Multimodal therapies may be necessary to improve the BCR in patients with very-high-risk PCa.

Abstract
BACKGROUND An esophageal anastomotic stricture (EAS) after an esophageal atresia surgery occurs in approximately 4-60% of the cases, and its first-line therapy includes balloon dilatation. Oral balloon dilatation cannot be performed in some EAS cases; conversely, even if dilatation is possible, these strictures recur in some cases, necessitating a surgical procedure for repairing the stenosis. However, these procedures are invasive and have short- and long-term complications. If an EAS recurs repeatedly after multiple balloon dilations, gastroesophageal reflux disease (GERD) may be the underlying cause. A fundoplication procedure may be effective for treating a refractory EAS, as in the present case. CASE PRESENTATION A neonatal patient with type D esophageal atresia underwent thoracoscopic esophago-esophageal anastomosis at the age of 1 day, and her postoperative course was uneventful. Thereafter, the patient underwent gastrostomy for poor oral intake at the age of 3 months. After gastrostomy, the patient presented with a complete obstructive EAS. Balloon dilatation via the oral route was attempted; however, a guidewire could not be inserted into the EAS site. Hence, retrograde balloon dilatation via gastrostomy was performed successfully. However, the EAS recurred easily thereafter, and laparoscopic anti-reflux surgery was performed to prevent GERD. The anti-reflux surgery cured the otherwise refractory EAS and prevented its recurrence. CONCLUSIONS Retrograde balloon dilatation is another treatment option for an EAS. When an EAS recurs soon after dilatation, the patient must be evaluated for GERD; if severe GERD is observed, an appropriate anti-reflux surgery is required before dilating the EAS.

Abstract
Ovarian cancer has a poor prognosis and is difficult to detect in early stages. Therefore, developing new diagnostic markers for early-stage ovarian cancer is critical. Here, we developed a diagnostic marker for early-stage ovarian cancer on the basis of fatty acid metabolism characteristics of cancer cells. The expression of various fatty acid metabolizing enzymes such as stearoyl-CoA desaturase 1 (SCD1) was altered in early-stage ovarian cancer tissue compared with that in normal ovarian tissue. Changes in the expression of fatty acid metabolizing enzymes, particularly SCD1, in cancer tissues were found to alter concentrations of multiple free fatty acids (FFA) in serum. We were the first to show that fatty acid metabolic characteristics in tissues are related to the FFA composition of serum. Surprisingly, patients with stage I/II ovarian cancer also showed significant changes in serum levels of eight FFAs, which can be early diagnostic markers. Finally, using statistical analysis, an optimal early diagnostic model combining oleic and arachidic acid levels, fatty acids associated with SCD1, was established and confirmed to have higher diagnostic power than CA125, regardless of histology. Thus, our newly developed diagnostic model using serum FFAs may be a powerful tool for the noninvasive early detection of ovarian cancer. SIGNIFICANCE Measurement of serum FFA levels by changes in the expression of fatty acid metabolizing enzymes in tumor tissue would allow early detection of ovarian cancer. In particular, the SCD1-associated FFAs, oleic and arachidic acid, would be powerful new screening tools for early-stage ovarian cancer.

Abstract
BACKGROUND Congenital chylothorax (CCT) and postoperative chylothorax (POCT) are rare and difficult to treat. We report our treatment strategy and outcomes for chylothorax, including thoracoscopic surgery with indocyanine-green (ICG) near-infrared fluorescence lymphangiography. METHODS A retrospective review of patients with CCT and POCT from 2014 to 2021 was performed. After definitive diagnosis, conservative treatments with octreotide, followed by intravenous steroids as needed, were performed. Patients who were refractory to conservative treatment were transferred to surgical treatment, consisting of thoracoscopic lymphatic leak ligations using ICG intraoperative lymphangiography. The effectiveness of conservative and surgical treatment was then examined. RESULTS We included 19 cases of CCT and 31 cases of POCT. The 31 POCT patients included 23 of 84 postoperative patients with congenital diaphragmatic hernia (CDH), 7 of 54 postoperative patients with esophageal atresia (EA), and 1 of 3 postoperative patients with lymphatic malformation. The efficacy of conservative treatment was 12/19 for CCT, 22/23 for CDH, and 4/7 for EA. Surgical intervention was performed in 10 patients, and the rate of resolution of chylothorax within 3 weeks after surgery was 90%. CONCLUSION Thoracoscopic lymphatic leak ligations with intraoperative ICG lymphangiography are feasible and useful in patients with chylothorax refractory to conservative treatment.

Abstract
Urinary storage symptoms after low-dose-rate brachytherapy (LDR-BT) with iodine-125 have been noted to be less likely to improve to baseline compared to voiding symptoms. This study aimed to evaluate the chronological changes in the overactive bladder symptom score (OABSS) and the time-to-resolution of OABSS in patients undergoing LDR-BT. Patients with prostate cancer who underwent LDR-BT at Gifu University Hospital were enrolled. The OABSS was evaluated before and after LDR-BT. Patients were divided into the OABSS resolution and resolution delay groups, and the association between OABSS resolution delay and clinicopathological covariates was evaluated. In total, 237 patients were enrolled in this study, with a median follow-up of 88.3 months. The OABSS in both groups worsened at 3 months following operation and gradually recovered at 9 months; however, the OABSS in the resolution delay group tended to worsen again after that. In the multivariate analysis, preoperative OABSS and the change from baseline to maximal OABSS were associated with OABSS resolution. To our knowledge, this is the first study to evaluate the delayed resolution of OABSS after LDR-BT in patients with prostate cancer. A low baseline OABSS and significant changes in the OABSS from baseline were independent predictors of delayed OABSS resolution.

Abstract
A prostate-targeted biopsy (TB) core is usually collected from a site where magnetic resonance imaging (MRI) indicates possible cancer. However, the extent of the lesion is difficult to accurately predict using MRI or TB alone. Therefore, we performed several biopsies around the TB site (perilesional [p] TB) and analyzed the association between the positive cores obtained using TB and pTB and the Prostate Imaging Reporting and Data System (PI-RADS) scores. This retrospective study included patients who underwent prostate biopsies. The extent of pTB was defined as the area within 10 mm of a TB site. A total of 162 eligible patients were enrolled. Prostate cancer (PCa) was diagnosed in 75.2% of patients undergoing TB, with a positivity rate of 50.7% for a PI-RADS score of 3, 95.8% for a PI-RADS score of 4, and 100% for a PI-RADS score of 5. Patients diagnosed with PCa according to both TB and pTB had significantly higher positivity rates for PI-RADS scores of 4 and 5 than for a PI-RADS score of 3 (p < 0.0001 and p = 0.0009, respectively). Additional pTB may be performed in patients with PI-RADS ≥ 4 regions of interest for assessing PCa malignancy.

Abstract
A 39-year-old Japanese male patient presented with a chief complaint of gross hematuria persistent for two months. However, no relevant findings in the patient's medical and family history were observed. He was diagnosed with muscle-invasive bladder cancer, clinical stage T2bN0M0. After four courses of neoadjuvant chemotherapy with gemcitabine and cisplatin, the tumor size reduced by approximately 30%. The patient underwent robot-assisted radical cystectomy with standard lymph node dissection followed by intracorporeal ileal conduit reconstruction. Histologically, the tumor was diagnosed as a high-grade urothelial carcinoma invading the fatty tissue surrounding the bladder and metastasizing to the lymph nodes, with a pathological stage of ypT3aypN2M0. Four months after surgery, multiple metastases were detected, and treatment with pembrolizumab was initiated immediately. However, the patient did not respond to pembrolizumab. Therefore, a third-line treatment with enfortumab vedotin (EV) was initiated. Thereafter, the metastatic lesion shrank quickly, and the metastatic lesions almost disappeared after two courses of EV administration. Although new metastases were observed at other sites, there has been no regrowth to date. EV-related adverse events were not observed during follow-up. Eighteen months after the surgery, the patient remains alive with multiple metastases. Therefore, the sequence of treatment should be considered to maximize the therapeutic effect of EV, and, consequently, administering EV as early as possible may be important.

Abstract
BACKGROUND Immunoglobulin G4-related disease (IgG4-RD) is a systemic inflammatory disease and affected individuals typically present with an increased infiltration of IgG4-positive plasma cells in the pancreas, hepatobiliary tract, and liver but rarely in the gastrointestinal tract. CASE PRESENTATION A 12-year-old girl presented with vomiting and poor weight gain. Gastroscopy revealed duodenal stenosis and ulceration. Computed tomography revealed edematous duodenal wall thickening and air-fluid levels on the right side of the duodenum, which suggested duodenal perforation or penetration. She underwent pancreaticoduodenectomy, and IgG4-RD was diagnosed via histopathology. CONCLUSIONS This is the first pediatric case of isolated duodenal IgG4-RD resulting in duodenal obstruction after multiple ulcers. Gastrointestinal IgG4-RD should be among the differential diagnoses of unexplained gastrointestinal obstruction or ulceration even in children.

Abstract
BACKGROUND To compare chronological changes in lower urinary tract symptoms (LUTS) after low-dose-rate prostate extended-release therapy (LDR-BT) using the overactive bladder symptom score (OABSS) in patients aged ≥ 75 years (elderly group) versus those aged < 75 years (control group). MATERIALS AND METHODS Patients with prostate cancer who underwent LDR-BT at Gifu University Hospital were included in this study. The International Prostate Symptom Score (IPSS), OABSS, and quality of life-based on urinary symptoms (IPSS-QOL) were evaluated before and after LDR-BT. We compared chronological changes in IPSS, OABSS, and IPSS-QOL in the elderly group with those in the control group and assessed the association between the resolution of OABSS and clinicopathological covariates. RESULTS A total of 484 patients were enrolled in this study. In the elderly group, the total IPSS, OABSS, and frequency scores increased at 1 month postoperatively, whereas the control group showed an increase at 3 months postoperatively. Multivariate analysis identified changes from baseline to the maximum OABSS and pre-treatment OABSS as significant predictors of delayed resolution of OABSS after LDR-BT. CONCLUSIONS Changes in pre-treatment OABSS and pre- and post-LDR-BT OABSS values were independent predictors of delayed resolution of OABSS; however, no correlation was found with age.

Abstract
Combretastatin A4 disodium phosphate (CA4DP) is a prodrug of combretastatin A4 (CA4), a microtubule-disassembling agent that exhibits antitumor effects by inhibiting tumor cell proliferation and inducing morphological changes and apoptosis in vascular endothelial cells in tumors. However, cardiotoxicity induced by ischemia and hypertension is a severe adverse event. In this study, we focused on the fact that phosphodiesterase (PDE) 5 inhibitors dilate the heart and peripheral blood vessels and aimed to investigate whether co-administration of tadalafil, a PDE5 inhibitor, can attenuate cardiotoxicity without altering the antitumor effect of CA4DP. To investigate cardiotoxicity, CA4DP and/or tadalafil were administered to rats, and blood pressure, echocardiography, histopathology, and cGMP concentration in the myocardium were examined. Administration of CA4DP increased systolic blood pressure, decreased cardiac function, lowered cGMP levels in the myocardium, and led to necrosis of myocardial cells. Co-administration of tadalafil attenuated these CA4DP-induced changes. To investigate the antitumor effect, canine mammary carcinoma cell lines (CHMp-13a) and human umbilical vein endothelial cells were cultured with CA4 and/or tadalafil, and cell proliferation and endothelial vascular tube disruption were examined. CHMp-13a cells were transplanted into nude mice and treated with CA4DP and/or tadalafil. CA4-induced inhibition of cell proliferation and disruption of the endothelial vascular tube were not affected by co-treatment with tadalafil, and the antitumor effects of CA4DP in xenograft mice were not reduced by co-administration of tadalafil. These results revealed that myocardial damage induced by CA4DP was attenuated by co-administration of tadalafil while maintaining antitumor efficacy.

Abstract
Congenital duodenal atresia with situs inversus is occasionally accompanied by a preduodenal portal vein (PDPV), which is incidentally diagnosed during surgery. Duodenoduodenostomy is the most common and effective treatment. However, some patients require other anastomoses. Here, we present two cases of laparoscopic gastrojejunostomy for congenital duodenal atresia with situs inversus and PDPV and describe the reason for selecting gastrojejunostomy. The optimal surgical strategy is patient specific and should be determined based on the patient's general and physical condition.

Abstract
A 78-year-old male visited the referring hospital because of asymptomatic gross hematuria. The patient was diagnosed with bladder cancer, clinical stage T3aN2M0, after multiple tumors were found in the bladder by cystoscopy and bilateral obturator lymph node metastases were found by contrast-enhanced thoracoabdominal-pelvic computed tomography. After neoadjuvant chemotherapy, the patient underwent robot-assisted radical cystectomy and pelvic lymph node dissection, followed by bilateral ureterocutaneostomy for urinary diversion. Postoperatively, the drainage volume from the pelvic drain ranged from 1,000 to 3,000 ml/day. We suspected lymphatic leakage based on the results of biochemical tests of the drainage fluid. Lymphangiography was conducted to confirm the diagnosis of lymphatic leakage, and lymphatic embolization was performed simultaneously. The patient underwent lymphangiography four times, but the lymphatic leakage persisted. Surgical treatment was considered, and lymphangioscintigraphy was conducted to search for areas of lymphatic leakage that could not be delineated by lymphangiography. Ascites decreased significantly after lymphangioscintigraphy.

Abstract
BACKGROUND This retrospective single-center cohort study evaluated the efficacy and safety of a combination of neoadjuvant luteinizing hormone-releasing hormone (LHRH) antagonist and tegafur-uracil (UFT) therapy (NCHT) and investigated the medical records of patients with high-risk PCa who underwent robot-assisted radical prostatectomy (RARP). The therapy was followed by RARP for high-risk PCa. MATERIALS AND METHODS The enrolled patients were divided into two groups: low-intermediate-risk PCa patients who underwent RARP without neoadjuvant therapy (non-high-risk) and those who underwent NCHT followed by RARP (high-risk group). This study enrolled 227 patients (126: non-high-risk and 101: high-risk group). Patients in the high-risk-group had high-grade cancer compared to those in the non-high-risk-group. RESULTS At the median follow-up period of 12.0 months, there were no PCa deaths; two patients (0.9%) died of other causes. Twenty patients developed biochemical recurrence (BCR); the median time until BCR was 9.9 months after surgery. The 2-year biochemical recurrence-free survival rates were 94.2% and 91.1% in the non-high-risk and high-risk-group, respectively (p = 0.465). Grade ≥3 NCHT-related adverse events developed in nine patients (8.9%). CONCLUSIONS This study indicates that combining neoadjuvant LHRH antagonists and UFT followed by RARP may improve oncological outcomes in patients with high-risk PCa.

Abstract
Small bowel bleeding that does not respond to conservative therapy requires surgical resection. However, identifying the bleeding sites intraoperatively is challenging. Indocyanine green (ICG) fluorescence imaging improves diagnosis of small bowel bleeding and surgical decision-making by visualizing blood flow. Herein, we reported two cases of small bowel bleeding that were successfully treated by using ICG to identify the bleeding sites and determine the extent of small bowel resection. The patients were a 46-year-old and a 75-year-old woman, both of whom presented with melena. Contrast-enhanced computed tomography and arteriography confirmed small bowel bleeding, and rebleeding occurred in both patients after transcatheter arterial embolization. Emergent surgeries were performed, and intraoperative selective angiography with ICG injections was conducted to identify obscure bleeding sites. ICG fluorescence identified all bleeding sites in both cases, and small bowel resections were successfully performed. The postoperative courses were uneventful, and both patients had a favorable postoperative course without recurrence of bleeding. ICG fluorescence imaging can safely identify the sites of intestinal bleeding and determine the appropriate extent of bowel resection.

Abstract
Chronic pain and attention-deficit hyperactivity disorder (ADHD) frequently coexist. However, the common pathology is still unclear. Attenuated noradrenergic endogenous analgesia can produce acute pain chronification, and dysfunction of noradrenergic systems in the nervous system is relevant to ADHD symptoms. Noxious stimuli-induced analgesia (NSIA) is measured to estimate noradrenergic endogenous analgesia in spontaneously hypertensive rats (SHR) as an ADHD model and control. Recovery of pain-related behaviors after paw incision was assessed. Contributions of noradrenergic systems were examined by in vivo microdialysis and immunohistochemistry. The SHR showed attenuated NSIA and needed a more extended period for recovery from acute pain. These results suggest ADHD patients exhibit acute pain chronification due to pre-existing attenuated noradrenergic endogenous analgesia. Immunohistochemistry suggests abnormal noradrenaline turnover and downregulation of the target receptor (alpha2a adrenoceptor). Standard ADHD treatment with atomoxetine restored NSIA and shortened the duration of hypersensitivity after the surgery in the SHR. NSIA protocol activated the locus coeruleus, the origin of spinal noradrenaline, of both strains, but only the control exhibited an increase in spinal noradrenaline. This result suggests dysfunction in the noradrenaline-releasing process and can be recognized as a novel mechanism of attenuation of noradrenergic endogenous analgesia.

Abstract
Combretastatin A4 (CA4) inhibits microtubule polymerization, and clinical trials of the prodrug, CA4 disodium phosphate (CA4DP), as an anti-cancer agent have been conducted. However, CA4DP has not been marketed to date because the margin between the effective dose and the cardiotoxic dose is insufficient. Meanwhile, bromodomain-containing protein 4 (BRD4) has been reported to be required for recovery from mitotic arrests induced by anti-microtubule drugs. BRD4 has also been reported to be involved in the progression of heart failure. Therefore, we hypothesized that the combined use of CA4DP with BRD4 inhibitors can enhance the antitumor effect and attenuate CA4DP-induced cardiotoxicity. In this study, the antitumor effect and cardiotoxicity caused by the co-administration of CA4DP with JQ1, a BRD4 inhibitor, were evaluated. CA4 or JQ1 alone reduced the viability of cultured canine mammary tumor cells (CHMp-13a). Viability was further reduced by co-administration, through the suppression of c-Myc. BRD4 positivity in CHMp-13a cytoplasm showed a significant increase when treated with CA4 alone, while the increase was not significant following co-administration. In CHMp-13a xenograft-transplanted mice, co-administration of CA4DP and JQ1 suppressed tumor growth significantly. In CA4DP-induced cardiac injury model rats, echocardiography showed a CA4DP-induced decrease in cardiac function and histopathology showed cardiomyocyte necrosis. Meanwhile, these cardiac changes tended to be milder following the co-administration of CA4DP and JQ1. These results suggest that CA4DP-JQ1 co-administration enhances the antitumor effect of CA4DP while attenuating its cardiotoxicity and therefore potentially open the doors to the development of a novel cancer chemotherapy with reduced cardiotoxicity risks.

Abstract
A 78-year-old man presented with a large abdominal mass detected by ultrasonography during a regular checkup. Even if the mass was > 10 cm in diameter, he was asymptomatic. Computed tomography detected an oval-shaped mass, with a maximum diameter of 12 cm, adjacent to the greater curvature of the stomach. Esophagogastroduodenoscopy revealed a 20 mm slightly depressed (type 0-IIc) lesion on the posterior wall of the gastric antrum, which was confirmed to be adenocarcinoma. Three cycles of combination chemotherapy with S-1 and oxaliplatin were administered as neoadjuvant chemotherapy. After neoadjuvant chemotherapy, the patient underwent distal gastrectomy, and a histopathological study identified the 12 cm giant mass as a lymph node metastasis. The postoperative course was uneventful, and thus far, the patient has completed adjuvant chemotherapy without relapse. Cases of gastric cancer with a giant lymph node metastasis are extremely rare. In this study, we report the present case and review the previous literature.

Abstract
We evaluated the efficacy and safety of combination therapy with immune checkpoint inhibitors (ICIs) and tyrosine kinase inhibitors (TKI) as first-line therapy for patients diagnosed as having advanced or metastatic renal cell carcinoma (mRCC). We enrolled 51 patients to receive ICI+TKI therapy for mRCC at 9 Japanese institutions. The overall survival (OS) of the patients treated with ICI+TKI was the primary endpoint., and the secondary endpoints were progression-free survival (PFS), objective response rate (ORR), and disease control rate (DCR). Furthermore, we analyzed the clinical prognostic and predictive factors in patients with mRCC treated with ICI+TKI therapy. Seven months was the median follow-up period. The OS rates at 6, 12, and 18 months were 93.1, 82.5, and 68.8%, respectively. The median PFS for patients who received ICI+TKI was 19.0 months, ORR was 68.6%, and DCR was 88.2%. ICI+TKI-related adverse events occurred in 43 patients (84.3%) with any grade and in 22 patients (43.1%) with grade ≥3. Treatment selection with poor prognostic factors may be prudent, even though ICI+TKI is an efficacious and safe first-line treatment in patients with mRCC.

Abstract
Purpose: A laparoscopic approach for malrotation is feasible and safe in hemodynamically stable neonates without intestinal necrosis; however, volvulus is associated with recurrence and conversion. We developed a novel approach using a laparoscopic duodenal-caudal detachment method to perform the Ladd procedure for neonates with volvulus under the limited view of laparoscopy. This study presents the results, effectiveness, and details of the method. Materials and Methods: In the laparoscopic duodenal-caudal detachment method, we first detached the adhesions around the duodenum, including the Ladd's band. After the adhesions were completely removed, the duodenum was freely drawn caudally, leading to the release of torsion. We retrospectively reviewed the medical records of patients who underwent surgery for malrotation of the volvulus at 30 days of age between January 2014 and September 2021. Results: Seven neonates underwent the laparoscopic duodenal-caudal detachment method and 13 underwent the open Ladd procedure. The new technique was performed in all 7 patients, and there were no conversions or recurrences. The operation time was significantly longer in the laparoscopic procedure group (55 minutes versus 111 minutes; P < .01). Conclusions: Our detorsion method, involving an initial incision of the Ladd's band, is safe and effective for neonates and may lead to an improvement in the conversion rates.

Abstract
Curcumin (Cur) has various biological effects, including anti-obesity and anti-diabetic properties. However, the molecular mechanisms by which Cur exerts these effects remain unclear. In addition, high doses of Cur have been administered in most animal and human trials to date, due mainly to the poor water solubility of native Cur and its low oral bioavailability. In our previous study, we demonstrated that a highly bioavailable Cur formulation (4.5 mg/kg) induces the formation of beige adipocytes in inguinal white adipose tissue (iWAT) in mice. In the present study, to enhance Cur-mediated beige adipocyte formation and reduce the required functional Cur dose, we investigated whether a low dose of Cur combined with exercise synergistically induced beige adipocyte formation. Cur (1.5 mg Cur/kg, daily) combined with exercise for 4 wk significantly induced beige adipocyte formation in iWAT in mice. This effect was associated with the elevation of interleukin-6 level following subsequent Cur administration combined with exercise. These results indicate that exercise combined with Cur synergistically enhances biological activity and reduces the required Cur dose. These findings suggest that Cur could be used as a dietary supplement during exercise to enhance exercise-mediated health benefits.

Abstract
Pheochromocytomas and paragangliomas are rare tumors. A 10 year-old girl was brought to the emergency room with complaints of sudden vomiting and convulsions, and was initially diagnosed with hypertensive encephalopathy. Magnetic resonance imaging and computed tomography scan showed a large mass (6 × 3 × 3 cm) on the dorsal side of the inferior vena cava, surrounded by the right diaphragmatic crus, and closely attached to the aorta. Blood noradrenaline, urinary normetanephrine, and noradrenaline levels were elevated. The final diagnosis was retroperitoneal paraganglioma, then, surgery was contemplated. The location of the liver and great vessels in front of the tumor made the commonly performed transabdominal approach complicated. Therefore, retroperitoneoscopic surgery was preferred for safer resection, with better visualization in a sufficient space with less risk of damaging the surrounding organs. The retroperitoneoscopic approach is a good indication for tumors located behind the great vessels.

Abstract
We report a case of hepatolithiasis 30 years after congenital biliary dilatation (CBD) surgery. A 31-year-old woman presented with fever and epigastric pain. She had a history of radical surgery for type I CBD at the age of 1 year and had no significant symptoms for approximately 30 years after surgery. Laboratory and imaging results showed hepatolithiasis at the common trunk of segments II and III with cholangitis. She was admitted to our hospital for antibiotics and underwent double-balloon endoscopic retrograde cholangiography (DBERC) to treat the hepatolithiasis. Roux-limb jejunum was perforated during DBERC; hence, emergent laparoscopic perforation site closure and simultaneous endoscopic lithotomy through the Roux-limb jejunum with exteriorization via umbilical incision were performed. The postoperative course was uneventful, and the patient was discharged without any complications.

Abstract
At the beginning of the COVID-19 pandemic in 2020, many hospitals around the world recommended stopping elective surgery as a precaution to stop the spread of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). The number of elective surgeries was reduced in Japan due to several waves of the pandemic. This work describes the management of COVID-19 and actual polymerase chain reaction (PCR) screening in operating theaters at the National Center for Global Health and Medicine (NCGM), a designated hospital for specified infectious diseases in Japan. The following three steps for COVID-19 infection control were taken to maintain the operating theater: i) Do not bring COVID-19 into the operating theater, ii) Infection control for all medical staff, and iii) Surgical management of surgical patients with COVID-19. We introduced checklists for surgical patients, simulations of surgery on infected patients, screening PCR tests for all surgical patients, and use of a negative pressure room for infective or suspected cases. We determined the flow and timing of surgery for patients with COVID-19. However, many aspects of COVID-19 infection control measures in the operating theater are still unclear. Therefore, infection control measures require further advances in the future to manage new infections.

Abstract
BACKGROUND The urachus is an embryonic structure that connects the bladder to the allantois during early embryonic development. Occasionally, it fails to disappear at birth, leading to a case of urachal remnant (UR). This study aimed to determine whether our policy for selecting an appropriate UR resection approach is valid. We performed preoperative imaging to examine whether UR continued toward the bladder apex. If so, the UR and bladder apex were excised using the trans-umbilical approach, in addition to laparoscopy, if necessary. If preoperative imaging indicated that the UR ended near the umbilicus, the UR from the umbilicus to the duct end was resected. Pathological evaluations were performed to determine the appropriateness of the surgical approach indicated by preoperative imaging. METHODS We retrospectively reviewed pediatric patients with UR who underwent surgery between 2015 and 2021. Their background characteristics and surgical outcomes were evaluated. RESULTS Twenty patients with UR were included (median age, 7 [interquartile range, 2-10.25] years). UR continued toward the bladder apex in 10 patients and ended near the umbilicus in 10 patients. Urachus tissue at the bladder site was observed when the UR and bladder apex were excised. When UR was resected from the umbilicus to the duct end, urachus tissue was not pathologically detected at the resection margin. CONCLUSION Our policy results in complete resection without excessive surgical invasion.

Abstract
A multicenter retrospective study was conducted to evaluate the efficacy and safety of cabozantinib in patients with advanced or metastatic renal cell carcinoma (mRCC). We enrolled 53 patients with mRCC who received cabozantinib at eight institutions in Japan. The primary endpoint was overall survival (OS). The secondary endpoints were objective response rate (ORR), disease control rate (DCR), and progression-free survival (PFS). In addition, we analyzed prognostic factors in patients with mRCC treated with cabozantinib. The median follow-up period was 8 months, and the median OS was 20.0 months. The ORR and DCR were 39.6% and 83.0%, respectively. The median PFS was 11.0 months. PFS was significantly shorter in patients previously treated with at least two tyrosine kinase inhibitors and in those with C-reactive protein (CRP) ≥ 1.27 mg/dL (p = 0.021 and p = 0.029, respectively). Adverse events of any grade and grades ≥3 occurred in 42 (79.2%) and 10 (18.9%) patients, respectively. Cabozantinib is a useful treatment option for patients with mRCC and may benefit from earlier use. In this study, CRP ≥ 1.27 mg/dL is a poor prognostic factor in patients treated with cabozantinib, and careful follow-up may be required in treating patients with high CRP.

Abstract
PURPOSE Gastrointestinal bleeding (GIB) due to esophageal varices (EV) is one of the factors that negatively impact native liver survival of patients with biliary atresia (BA). Gastrointestinal fibroscopy (GIF) is usually used to determine the presence of EVs; however, it requires general anesthesia. The aim of this study is to search for markers in blood tests obtained during routine check-ups that can predict the development of GIB. METHODS Data of patients with BA who underwent portoenterostomy at our hospital from 2014 to 2020 were retrospectively reviewed. The patients' data were assigned to three groups according to specific time points: Group B, which included data at GIB; Group NB-T, which included data at GIF and EV treatment; and Group NB-NT, which included data at GIF without treatment. The data in Group B were compared to those of other groups. RESULTS In our study, GIB occurred in 11 patients, and 12 cases and 8 cases were classified into Groups NB-NT and NB-T, respectively. Compared with the other groups, only ChE and M2BPGi in Group B showed statistically significant differences. CONCLUSIONS ChE and M2BPGi are useful for predicting GIB.

Abstract
Background The aim of this study is to investigate chronological changes of lower urinary tract symptoms (LUTS) in patients with prostate cancer who underwent low-dose-rate brachytherapy (LDR-BT) followed by the insertion of SpaceOAR® system (SpaceOAR). Methods In this retrospective study, 483 patients with localized prostate cancer underwent LDR-BT at the Gifu University Hospital between August 2004 and December 2020. SpaceOAR was inserted in 30 patients after LDR-BT (SpaceOAR group), and 453 patients received LDR-BT alone (non-SpaceOAR group). The International Prostate Symptom Score (IPSS), Overactive Bladder Symptom Score (OABSS), quality of life due to urinary symptoms (IPSS-QOL), and uroflowmetry (UFM), including maximum flow rate (Qmax), voided volume, and post-voided residual urine (PVR), were evaluated before LDR-BT, and at 1, 3, 6, 9, and 12 months after LDR-BT. The outcomes were chronological changes in IPSS, OABSS, and IPSS-QOL compared to pretreatment values and those of covariates in relation to UFM. Results The IPSS, OABSS, IPSS-QOL, Qmax, and voided volume were not significantly associated with either group. According to the PVR interaction effect, the insertion of SpaceOAR was significantly affected by chronological changes in PVR (P = 0.001). Three months after LDR-BT, PVR in the SpaceOAR group was significantly higher than that in the non-SpaceOAR group (49.8 mL vs. 30.5 mL; P = 0.002). Conclusion SpaceOAR use may temporally increase PVR; however, IPSS, OABSS, IPSS-QOL, Qmax, and voided volume were not significantly associated with LUTS before and after LDR-BT. The combination of LDR-BT and SpaceOAR may be acceptable for treating patients with prostate cancer regarding the chronological changes in LUTS after brachytherapy.

Abstract
Background Omphalocele is a congenital abdominal wall defect of the umbilical cord insertion site. A giant omphalocele, with a fascial defect > 5 cm in diameter and/or containing > 50% of the liver within the hernia sac, can be challenging for pediatric surgeons. Recently, negative pressure wound therapy has been reported as an effective management for giant omphaloceles; however, it is not recommended for an infected wound with necrotic tissue as it may exacerbate infection. We adopted negative pressure wound therapy with irrigation and dwell time (NPWTi-d) for a case of a ruptured giant omphalocele. Artificial membranes, followed by artificial dermis, were used to promote fibrous capsule formation, and then NPWTi-d was used to promote granulation while controlling infection. However, studies have not been conducted regarding NPWTi-d for ruptured giant omphaloceles; hence, we present our treatment experience with NPWTi-d for a giant omphalocele. Case presentation The patient was a boy born at 38 weeks and 3 days of gestation, weighing 1896 g. He was diagnosed with a ruptured giant omphalocele with a total liver and intestine defect hole of 10 cm × 10 cm. The patient underwent silo placement using an artificial mesh, followed by plicating the artificial mesh at 4 days of age. The herniated viscera were gradually reduced into the abdominal cavity; however, the defect size was still large. Hence, a collagen-based artificial dermis was patched on the defect hole. After creating a fresh and smooth granulated tissue, NPWTi-d was applied at 33 days of age to promote granulation and control infection. We used the 3 M™ V.A.C.® Ulta Therapy Unit with 3 M™ VeraFlo™ therapy. NPWTi-d was stopped at 60 days of age when the granulation tissue was well formed including at the artificial dermis site. The wound was managed with prostandin ointment and appropriate debridement, resulting in complete epithelialization at 5 months of age. Conclusions Artificial membranes followed by artificial dermis were used to promote a fibrous capsule and artificial dermis granulation, which protects against organ damage. NPWTi-d achieved better control of infection and promoted wound healing. NPWTi-d combined with artificial dermis can effectively treat ruptured giant omphaloceles.

Abstract
BACKGROUND Decision-making and selection of treatment modalities for newly diagnosed prostate cancer (PCa) are often determined by risk stratification using grade group (GG), prostate-specific antigen (PSA), and clinical stage. The discrepancies between needle biopsy (NB) and radical prostatectomy (RP) specimens often occur because of the sampling errors in NB or multifocal features of PCa. Thus, we aimed to estimate the preoperative clinical factors for predicting GG upgrading after robot-assisted RP (RARP). METHODS In this retrospective study, we reviewed the clinical and pathological records of patients who underwent RARP at Gifu University Hospital. We focused on patients with organ-confined PCa who had not received neoadjuvant therapy prior to RARP. The primary endpoint was identified as the predictive factor of GG upgrading for RARP specimens compared to those of NB specimens. RESULTS Eighty-one patients were included in this study. The enrolled patients were divided into two groups: those who had GG upgrading for RARP specimens (the NB upgrade group) or those who did not have GG upgrading (the no upgrade group). The median age of all patients was 70 years, and the median body mass index (BMI) was 22.9 kg/m2. The median neutrophil count was 3720/μL, lymphocyte count was 1543/μL, and neutrophil-to-lymphocyte ratio (NLR) was 2.24. In univariate analysis, BMI, PSA, neutrophil count, and NLR were significantly associated with GG upgrading in RARP specimens compared to NB specimens. BMI and NLR were identified as strong predictive factors for GG upgrading in RARP specimens in the multivariate analysis. CONCLUSIONS Although this study's small number of enrolled patients was a vital weakness, BMI and NLR might have been significantly correlated with GG upgrading for RP specimens compared with NB specimens. Therefore, BMI and NLR may have potential benefits for newly diagnosed patients with PCa in terms of decision-making and the selection of treatment modalities.

Abstract
We report an extremely rare case of a right Bochdalek hernia with a sac, in which the retroperitoneal and intra-abdominal organs prolapsed into the thoracic cavity at the same time. The patient was a 7-month-old female with no comorbidities. She presented with cough and fever, and chest radiography revealed a right diaphragmatic hernia. Computed tomography showed that the right kidney, intestine, colon, and liver had prolapsed into the thoracic cavity. The patient underwent thoracoscopic surgery, which showed that the abdominal and retroperitoneal organs prolapsed into the thoracic cavity through the Bochdalek hernia. The herniated organs were spontaneously reduced using thoracoscopic insufflation. The defect hole was closed with artificial mesh. We adopted a thoracoscopic approach, in terms of easy reduction of herniated organs and accurate evaluation of the hernia orifice, which was useful.

Abstract
This study aimed to evaluate the safety and effectiveness of circumumbilical incision (CUI) for neonates requiring intestinal anastomosis. Seventy neonates requiring intestinal anastomosis at our institution between 2003 and 2020 were included in this retrospective case-control study. Patients were classified into the CUI (25 patients: 36%) and transverse incision (TI) groups (45 patients: 64%). Postoperative complications and surgical outcomes were compared between the two groups. Intestinal perforation at the non-anastomotic site occurred significantly more often in the CUI group than in the TI group (3 patients: 12%, and 0 patients: 0%, respectively (p = 0.042)). There were no between-group differences regarding anastomotic leakages, anastomotic strictures, time to enteral feeding, operative time, and blood loss. Neonatal intestinal surgery employing CUI might be associated with increased intestinal perforation at the non-anastomotic site. Hesitating to enlarge the skin incision to maintain favorable cosmetic outcomes might cause severe injury to the delicate neonatal intestine during the surgical procedure owing to the restricted surgical field. When performing CUI, we suggest that the skin incision should be extended without hesitation whenever there is difficulty in manipulating the intestine.
