ABSTRACT
BACKGROUND: An ectopic bile duct opening into the stomach is a rare congenital anomaly of the biliary system, and thus, there are few case reports with gastric ulcer hemorrhage. Herein, we presented a case of ectopic bile duct concomitant with gastric ulcer hemorrhage. CASE PRESENTATION: A 75-year-old woman was referred to our hospital because she repeatedly vomited blood and had melena. Endoscopic hemostasis was attempted for hemorrhage from a gastric ulcer located on the anterior wall of the antrum. However, the bleeding was difficult to stop, and a laparoscopic distal gastrectomy was performed. Her postoperative course was uneventful. Pathological examination revealed that the bleeding point was an ectopic bile duct. In retrospect, an annual endoscopy performed at her family clinic had revealed a bulge in the same portion of the stomach. Exposure to bile acids from an ectopic bile duct opening can cause gastric mucosal damage and ulceration. CONCLUSIONS: Ectopic bile ducts opening into the stomach can cause gastric ulcer and hemorrhage. Hemorrhage from a submucosal ridge with ulcer in the stomach may be rarely related to the presence of ectopic bile ducts.
ABSTRACT
AIM: There are few data regarding the safety and effectiveness of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines in patients with intractable hepatobiliary diseases. We conducted a multicenter, questionnaire-based, cross-sectional study to determine the safety and effectiveness of the SARS-CoV-2 vaccines in Japanese patients with intractable hepatobiliary disease. METHODS: Patients aged ≥18 years with autoimmune hepatitis (AIH), primary biliary cholangitis, primary sclerosing cholangitis, Budd-Chiari syndrome, idiopathic portal hypertension, and extrahepatic portal vein obstruction at each center were consecutively invited to join the study. Participants were asked to complete a questionnaire regarding their characteristics, vaccination status, post-vaccination adverse effects, and SARS-CoV-2 infection. Additionally, liver disease status, treatment regimens, and liver function test values pre- and post-vaccination were collected. RESULTS: The survey was conducted from September 2021 to May 2022, and 528 patients (220 AIH, 251 primary biliary cholangitis, 6 AIH- primary biliary cholangitis/primary sclerosing cholangitis overlap, 39 primary sclerosing cholangitis, 4 Budd-Chiari syndrome, 5 idiopathic portal hypertension, and 3 extrahepatic portal vein obstruction) participated in the study. Post-vaccination adverse effects were comparable to those observed in the general population. Post-vaccination liver injuries classified as grade 1 or higher were observed in 83 cases (16%), whereas grades 2 and 3 were observed in only six cases (1.1%); AIH-like liver injury requiring treatment was not observed. Overall, 12 patients (2.3%) were infected with SARS-CoV-2, and only one patient was infected 6 months after the second vaccination. CONCLUSION: SARS-CoV-2 vaccines demonstrated satisfactory safety and effectiveness in Japanese patients with intractable hepatobiliary diseases.
ABSTRACT
PURPOSE: Obesity is known to be associated with colorectal adenoma (CRA) and colorectal cancer (CRC); yet colonoscopy is not considered an essential preoperative evaluation before bariatric/metabolic surgery. The aim of this study was to clarify the clinical significance of preoperative colonoscopy for obese Japanese patients. METHODS: The subjects of this retrospective study were 114 patients who underwent screening colonoscopy before bariatric/metabolic surgery. Multivariate analyses were performed to evaluate the independent predictors of CRA/CRC among the characteristics identified as significant or nearly significant by univariate analyses. RESULTS: Colonoscopy revealed abnormal findings indicating the need for biopsy or polypectomy in 20 of the 114 patients (17.5%), and CRA was diagnosed in 13 patients (11.4%). Three patients (2.6%), who were all ≥ 56 years old, had a CRA ≥ 10 mm in diameter. The multivariate analysis showed that older age and male sex were significant predictors of CRA/CRC, which was identified in 46.2% of the male patients aged ≥ 46 years. CONCLUSION: Our findings suggest that older age and male sex may be risk factors for CRA/CRC in obese Japanese candidates for bariatric/metabolic surgery; thus, preoperative colonoscopy should be considered for these high-risk patients.

BACKGROUND: Multidisciplinary therapy centered on antitumor drugs is indicated in patients with unresectable pancreatic neuroendocrine tumors (PanNET). However, the criteria for selection of optimal therapeutic agents is controversial. The aim of this study was to assess the malignancy of PanNET for optimal therapeutic drug selection. METHODS: Forty-seven patients with PanNET who underwent surgery were reviewed retrospectively, and immunohistochemical characteristics, including expression of GLUT1, SSTR2a, SSTR5, Survivin, X-chromosome-linked inhibitor of apoptosis protein (XIAP), and Caspase3 in the resected specimens, were investigated. Relapse-free survival (RFS) and overall survival (OS) were evaluated with regard to the characteristics using the Kaplan-Meier method and compared with the log-rank test. RESULTS: GLUT1 expression showed significant correlation with sex (p = 0.036) and mitotic rate (p = 0.048). Survivin and XIAP expression showed significant correlation with T-stage (p = 0.014 and 0.009), p-Stage (p = 0.028 and 0.045), and mitotic rate (p = 0.023 and 0.007). XIAP expression also significantly influenced OS (p = 0.044). CONCLUSIONS: Survivin and XIAP correlated with grade of malignancy, and expression of XIAP in particular was associated with a poor prognosis. Expression of these proteins may be a useful indicator to select optimal therapeutic agents in PanNET.

BACKGROUND: Laparoscopic repeat hepatectomy (LRH) has increased, but appropriate indications for LRH are unclear. This study aimed to clarify appropriate indications for LRH. METHODS: We retrospectively compared surgical outcomes between open RH (ORH) (n = 57) and LRH (n = 40) groups. To detect difficult cases of complete pure LRH, we examined patients with unplanned intraoperative hand-assisted laparoscopic surgery (HALS)/open conversion (n = 6). RESULTS: In the LRH versus ORH group, as previous hepatectomy, laparoscopic (75% vs. 12%, p < 0.001) and partial hepatectomy (Hr0) (73% vs. 37%, p = 0.002) were more frequently performed, and as RH procedure, partial hepatectomy (Hr0) (88% vs. 47%, p = 0.0002) was more frequently performed. S1 tumor cases were higher in ORH group (11% vs. 0%), but S2-6 cases were higher in LRH group (73% vs. 49%) (p = 0.02). In LRH group, compared to the pure LRH patients, HALS/open conversion patients underwent significantly more previous hepatectomy with more than lobectomy (Hr2-3) (33% vs. 2.9%, p = 0.033) and more RH procedures with segmentectomy (HrS) (33% vs. 2.9%, p = 0.03). All LRH requiring a repeat hepatic hilar approach were HALS conversions. CONCLUSION: Appropriate indications for LRH were previous hepatectomy was laparoscopic partial hepatectomy (Hr0), and RH procedure was partial hepatectomy (Hr0) for S2-6 tumor location. When RH is more than segmentectomy (HrS) requiring a repeat hepatic hilar approach, planned HALS or ORH may be a better approach than pure LRH.

Aims: We evaluated a self-care intervention with a novel mobile application (app) in chronic heart failure (HF) patients. To facilitate patient-centred care in HF management, we developed a self-care support mobile app to boost HF patients' optimal self-care. Methods and results: We conducted a multicentre, randomized, controlled study evaluating the feasibility of the self-care support mobile app designed for use by HF patients. The app consists of a self-monitoring assistant, education, and automated alerts of possible worsening HF. The intervention group received a tablet personal computer (PC) with the self-care support app installed, and the control group received a HF diary. All patients performed self-monitoring at home for 2 months. Their self-care behaviours were evaluated by the European Heart Failure Self-Care Behaviour Scale. We enrolled 24 outpatients with chronic HF (ages 31-78 years; 6 women, 18 men) who had a history of HF hospitalization. During the 2 month study period, the intervention group (n = 13) showed excellent adherence to the self-monitoring of each vital sign, with a median [interquartile range (IQR)] ratio of self-monitoring adherence for blood pressure, body weight, and body temperature at 100% (92-100%) and for oxygen saturation at 100% (91-100%). At 2 months, the intervention group's self-care behaviour score was significantly improved compared with the control group (n = 11) [median (IQR): 16 (16-22) vs. 28 (20-36), P = 0.02], but the HF Knowledge Scale, the General Self-Efficacy Scale, and the Short Form-8 Health Survey scores did not differ between the groups. Conclusion: The novel mobile app for HF is feasible.
ABSTRACT
Rapid reperfusion by primary percutaneous coronary intervention (pPCI) is an established strategy for the treatment of patients with ST-segment elevation myocardial infarction (STEMI). Pre-hospital electrocardiogram (PH-ECG) transmission by the emergency medical services (EMS) facilitates timely reperfusion in these patients. However, evidence regarding the clinical benefits of PH-ECG in individual hospitals is limited.This retrospective, observational study investigated the clinical efficacy of PH-ECG in STEMI patients who underwent pPCI. Of a total of 382 consecutive STEMI patients, 237 were enrolled in the study and divided into 2 groups: a PH-ECG group (n = 77) and non-PH-ECG group (n = 160). Door-to-balloon time (D2BT) was significantly shorter in the PH-ECG group (66 [52-80] min), compared to the non-PH-ECG group (70 [57-88] minutes, P = 0.01). The 30-day all-cause mortality rate was 6% in the PH-ECG group, which was significantly lower than that in the non-PH-ECG group (16%) (P = 0.037, hazard ratio [HR]: 0.38, 95% CI: 0.15-0.98). This trend was particularly evident in severely ill patients when stratified by GRACE score.The use of PH-ECG improved the survival rate of STEMI patients undergoing pPCI due to the improved pre-arrival preparation based on the EMS information. Coordination between EMS and PCI-capable institutes is essential for the management of PH-ECG.

AIM: The number of surgeries for pancreatic ductal adenocarcinoma (PDAC) in older adults has been rising. This study aimed to evaluate the technical and oncological safety of pancreatectomy for older adults aged ≥75 years with PDAC by retrospectively comparing their short- and long-term outcomes with those of younger adults aged <75 years. METHODS: Data were collected from 117 patients who underwent pancreatectomy for PDAC in our department. The indication for surgery regarding patient characteristics was considered according to each patient's American Society of Anesthesiologists physical status and Eastern Cooperative Oncology Group Performance Status Scale. Data of older adults (n = 32) were compared with those of younger adults (n = 85), and comprised patient background, surgical factors, postoperative course, histopathological factors and prognostic factors. Additionally, prognostic nutritional index values preoperatively and at 1 and 6 months postoperatively were compared between the two groups. RESULTS: Although American Society of Anesthesiologists physical status and comorbidities were worse in older adults, there were no significant differences in surgical factors, postoperative courses and histopathological factors between the two groups. The overall complication rate tended to be higher in older adults (40.6%) than in younger adults (29.4%). There were no differences in median lengths of recurrence-free survival and overall survival (older adults vs younger adults: 12 vs 13 months, P = 0.545, and 26 vs 20 months, P = 0.535, respectively) between the two groups. Furthermore, no significant differences were found in prognostic nutritional index preoperatively to 6 months after surgery. CONCLUSION: With careful determination of surgical indications, pancreatectomy for PDAC can be carried out with acceptable post-pancreatectomy morbidity in younger adults.

BACKGROUND: The prognosis of distal cholangiocarcinoma (dCCA) remains poor; thus, the identification of new therapeutic targets is warranted. Phosphorylated S6 ribosomal protein indicates a mammalian target of rapamycin complex 1 (mTORC1) activity, and mTORC1 plays a central role in controlling cell growth and regulating glucose metabolism. We aimed to clarify the effect of S6 phosphorylation on tumor progression and the glucose metabolic pathway in dCCA. METHODS: Thirty-nine patients with dCCA who underwent curative resection were enrolled in this study. S6 phosphorylation and the expression of GLUT1 were evaluated by immunohistochemistry, and their relationship with clinical factors was investigated. The effect of S6 phosphorylation on glucose metabolism with PF-04691502 treatment, an inhibitor of S6 phosphorylation, was examined in cancer cell lines by Western blotting and metabolomics analysis. Cell proliferation assays were performed with PF-04691502. RESULTS: S6 phosphorylation and the expression of GLUT1 were significantly higher in patients with an advanced pathological stage. Significant correlations between GLUT1 expression, S6 phosphorylation, and SUV-max of FDG-PET were shown. In addition, cell lines with high S6 phosphorylation levels showed high GLUT1 levels, and the inhibition of S6 phosphorylation reduced the expression of GLUT1 on Western blotting. Metabolic analysis revealed that inhibition of S6 phosphorylation suppressed pathways of glycolysis and the TCA cycle in cell lines, and then, cell proliferation was effectively reduced by PF-04691502. CONCLUSION: Upregulation of glucose metabolism via phosphorylation of S6 ribosomal protein appeared to play a role in tumor progression in dCCA. mTORC1 may be a therapeutic target for dCCA.

INTRODUCTION: Laparoscopic sleeve gastrectomy (LSG) for morbidly obese patients often results in remission of type 2 diabetes (T2DM), but diabetes relapses in some of those patients. The frequency of T2DM relapse in Asians and the factors involved have not been adequately investigated. METHODS: The J-SMART study was conducted on 322 Japanese subjects with body mass index (BMI) ≥32 kg/m2 who underwent LSG at 10 accredited centers in Japan between 2011 and 2014. Of these, 82 T2DM subjects with diabetes in complete or partial remission at 1 year after LSG and followed postoperatively for 5 years were included in the subgroup analysis and classified into two groups: diabetes remission-maintained and diabetes relapse. RESULTS: The mean age of all included subjects was 49.2 years, median BMI was 41.5 kg/m2, and median HbA1c was 6.7%. Compared with the diabetes remission-maintained group, the diabetes relapse group at 5 years after LSG had significantly higher preoperative HbA1c, number of antidiabetic medications, and high-density lipoprotein cholesterol level; and lower BMI and homeostasis model assessment-beta cell function (HOMA-ß). As many as 83.0% of the subjects were able to achieve HbA1c <7% at 5 years after LSG, but 26.8% of the subjects had diabetes relapse. Preoperative HbA1c significantly contributed to diabetes relapse (odds ratio 1.54, p = 0.049). In addition, the diabetes relapse group tended to have lower percentage total weight loss (%TWL) at 1 year after LSG and higher percentage weight regain (%WR) from postoperative nadir weight, compared with the diabetes remission-maintained group. The hazard ratio for diabetes relapse was 3.14-fold higher in subjects with %TWL ≥20% and %WR ≥25%, and 5.46-fold higher in those with %TWL <20% and %WR ≥25%, compared with %TWL ≥20% and %WR <25%. CONCLUSION: While LSG provides a high remission rate for T2DM, relapse is not uncommon. Preoperative HbA1c, poor weight loss, and excess weight regain after LSG contribute to diabetes relapse, suggesting the importance of treatment strategies focusing on these factors.

Background: Japanese pediatric endosurgery experts conducted a workshop for young pediatric surgeons in Russia in collaboration with Russian expert pediatric surgeons. This study was aimed to develop a contributive workshop program and evaluate its impact on young pediatric surgeons. Methods: A 2-day pediatric endosurgery workshop was held in Moscow in February 2020. After conducting a needs assessment survey, Japanese and Russian faculties developed the workshop contents, including pre- and postworkshop skills assessments, lectures, and hands-on training. Skills assessments were performed using the objective skill validation system, the "A-Lap Mini," mimicking intestinal anastomosis. The trainees self-evaluated their knowledge and skills using a five-point scale. Results: Fifteen novice trainee participated and 14 (93.3%) completed the workshop program. The completion rate for the suturing task before and after the workshop was 40.0% (6/15) and 85.7% (12/14), respectively. The following five skill evaluation criteria, which were objectively evaluated: performance time changed from 751.6 ± 247.1 seconds to 780.0 ± 313.3 seconds (P > .05), number of full-thickness sutures improved from 1.0 ± 1.41 to 2.64 ± 0.84 (P = .003), area of wound-opening changed from 0.42 ± 0.83 mm2 to 0.53 ± 1.13 mm2 (P > .05), suture tension improved from 55.48% ± 19.51% to 61.95% ± 23.91% (P > .05), and maximum air leakage pressure improved from 3.76 ± 2.11 kPa to 8.42 ± 7.68 kPa (P > .05). Regarding the self-assessed questionnaire administered before and after the workshop, the confidence in endosurgery skills significantly improved as follows: forceps manipulation ability improved from 2.7 to 3.7 (P < .05), and suturing performance improved from 2.5 to 3.6 (P < .05). The usefulness of the workshop for clinical surgery was scored at 4.3. Conclusions: Quantitative skill evaluation with an automatic feedback function was useful for endosurgery training. Delivering feedback concerning the assessment results to the trainee helps them to determine the specific training requirements needed for clinical endosurgery.

ABSTRACT
BACKGROUND: There are multiple surgical procedures for resecting non-ampullary duodenal neoplasms (NADNs), and the appropriate method is selected depending on the tumor location and diagnosis. We herein report 3 cases of NADNs that were resected using pancreas-preserving partial duodenectomy (PPD). CASE REPORTS: The first patient, a 73-year-old woman with a circumferential duodenal adenoma in the supra-ampullary duodenum, underwent surgery. After laparotomy, the duodenum proximal to the tumor was confirmed using intraoperative endoscopy and dissected. The duodenum distal to the tumor was dissected under direct visualization, and the specimen was removed. The distal stump of the duodenum was closed, and duodenojejunostomy was performed as described by Billroth II. The tumor was diagnosed as an adenoma 75 mm in size. She was discharged 12 days after surgery without any complications. The second patient, a 48-year-old man, was diagnosed with a neuroendocrine neoplasm (NEN) with a diameter of 14 mm in the supra-ampullary duodenum. Laparoscopic PPD was performed. He was diagnosed with NEN G1 and discharged the 11th day after surgery. The third patient, a 71-year-old man with a 0-Is + IIa lesion in the horizontal duodenum, underwent surgery. After laparotomy, the horizontal duodenum and proximal jejunum were resected, and duodenojejunostomy was performed. The patient was diagnosed with stage I adenocarcinoma and discharged on the 15th day after surgery. CONCLUSION: PPD is useful for avoiding the morbidity of pancreatoduodenectomy in the management of NADNs without invasion to the ampulla of Vater or pancreas.
ABSTRACT
A 47-year-old man with symptomatic paroxysmal atrial fibrillation (AF) underwent AF ablation. Activation maps during right atrial pacing and sinus rhythm before the ablation revealed distinctive left atrial (LA) propagations with multiple LA breakthrough sites via epicardial connections. A wide area circumferential ablation was not able to achieve a right pulmonary vein (RPV) isolation and required an inner PV ablation to isolate the RPV. Activation maps during different rhythms before the ablation may be helpful to unmask multiple epicardial connections between the RPV and right atrium.

BACKGROUND: Short-chain fatty acids (SCFAs) and gut microbiota have health-related effects and are associated with a wide range of disorders. However, the changes of SCFAs and their receptors after sleeve gastrectomy (SG) remain unclear. This study aimed to examine changes of SCFAs and their receptors after SG in an obese rat model. METHODS: Thirty obese Sprague-Dawley rats eating a high-energy diet for 6 weeks were divided into three groups: sham-operated (SO) control, pair-fed (PF) control, and SG group. Six weeks after the surgery, metabolic parameters, SCFA levels in the blood and stool, mRNA and protein expression of SCFA receptors in the ileum and epididymal fat, and gut microbiota were examined. RESULTS: Metabolic parameters in the SG group were significantly improved compared with the SO group. Acetic acid levels in the blood and stool were significantly higher in the SG group than the PF group. The butyric acid level in the stool was also significantly higher in the SG group than in the PF group. In the ileum and epididymal fat, mRNA and protein expression of GPR41 was significantly higher in the SG group than in the other two groups, and mRNA and protein expression of GPR43 was significantly higher in the SG group than in the PF group. Increases in the genera Enterococcus, Lactobacillus, Lactococcus, and Clostridium were observed in the stool after SG. CONCLUSIONS: SG may activate SCFA pathways through a change in gut microbiota.

BACKGROUND: On November 25, 2021, the IFSO-Asia-Pacific Chapter (IFSO-APC) Virtual Meeting 2021 was held online, and the representatives from the Asia-Pacific region presented 10 years of change in bariatric/metabolic surgery and the influence of COVID-19 in the special session of "IFSO-APC National Reports 2010-2020". We herein report the summarized data. METHODS: National bariatric/metabolic surgery data, which included the data of 2010 and 2020, were collected from the representatives using a questionnaire that consisted of 10 general questions. At the congress, the data were calculated and summarized. RESULTS: Thirteen of the 14 national societies responded to the survey. From 2010 to recent years, the populations of individuals with obesity (BMI ≥ 30 kg/m2) and individuals with diabetes both significantly increased. Eight countries and regions expanded the lower limit of criteria for bariatric surgery by 2-5 kg/m2 (BMI), and 5 countries newly established criteria for metabolic surgery in the last ten years. Sixty-nine percent of the countries currently run public health insurance systems, which doubled from 2010. The number of bariatric surgeons and institutions increased more than threefold from 2010. In 2010, 2019, and 2020, surgeons in IFSO-APC societies performed 18,280, 66,010, and 49,553 bariatric/metabolic surgeries, respectively. Due to the COVID pandemic, restriction policies significantly reduced access to surgery in South and Southeast Asian countries. The biggest changes included increased numbers of bariatric surgeons and institutions, operation numbers, public insurance coverage, raising awareness, and national registry systems. CONCLUSION: For the last 10 years, bariatric/metabolic surgery has rapidly grown in the Asia-Pacific region.

INTRODUCTION: The psychosocial background of subjects with severe obesity developed from childhood onset obesity (CO) and their outcomes after bariatric surgery have not been fully investigated. METHODS: 305 subjects were enrolled in the J-SMART study, which examined the effects of laparoscopic sleeve gastrectomy (LSG) in Japan, and categorized into two groups: CO defined as onset up to 13 years of age (CO group) and post-puberty onset obesity defined as onset after 13 years of age (PPO group). The subjects were followed up for at least 2 years and up to 5 years after LSG. Changes in physical parameters and remission of obesity-related comorbidities were assessed at 2 years after LSG. Weight regain (WR) was also assessed by evaluating the nadir weight after LSG and maximum weight thereafter during follow-up period. RESULTS: The mean postoperative follow-up period was 3.0 ± 1.1 years. 40.0% of the subjects had CO and these subjects had higher BMI and HOMA-ß and lower age, HbA1c, HDL cholesterol, and visceral/subcutaneous fat area ratio compared to those with PPO. The CO group was also characterized by having higher rates of mental retardation, developmental disorders, and obesity in either parent and lower rate of marriage compared to the PPO group. Two years after LSG, there were no differences in total weight loss and remission rates of diabetes, dyslipidemia, and sleep apnea syndrome between the two groups, although remission rate of hypertension was higher in the CO group. The CO group also had a higher rate of WR after LSG than the PPO group, with CO, BMI, mental disorder, and binge eating contributing to WR. CONCLUSION: This study suggests that CO might be associated with genetic and psychosocial factors. CO and PPO probably differ in pathogenesis and may require different treatment strategies.
