Abstract
Background and Aim Anticoagulant users with nonvalvular atrial fibrillation (NVAF) sometimes suffer from gastrointestinal bleeding (GIB) and have difficulty continuing the medication. Left atrial appendage closure (LAAC) has been developed for such situations. We aimed to clarify the clinical significance of a history of GIB in comparison to other factors in patients who had undergone LAAC. Methods From October 2019 to September 2023, patients with NVAF who underwent LAAC at our hospital were enrolled. We investigated the percentage of patients with a history of GIB who underwent LAAC and compared the incidence of post-LAAC bleeding in these patients compared to those with other factors. Results A total of 45 patients were included. There were 19 patients (42%) with a history of GIB who underwent LAAC. In a Kaplan-Meier analysis, the cumulative incidence of bleeding complications after LAAC was significantly higher in patients with a history of GIB in comparison to patients with other factors. There were eight cases of post-LAAC bleeding in total, and seven cases had GIB. Conclusions We need to recognize that GIB is a significant complication in patients who undergo LAAC. The management of GIB by gastroenterologists is essential to the success of LAAC.

Abstract
BACKGROUND AND AIM The endoscopic features of gastric neuroendocrine carcinoma (G-NEC) have not been clarified; therefore, they were investigated in relation to clinicopathological findings. METHODS Consecutive patients with G-NECs who had undergone endoscopic or surgical resection at our institution between January 2005 and March 2022 were included in this retrospective study. The endoscopic and clinicopathological findings of the lesions were analyzed to provide information of diagnostic value. In addition, cases of gastric neuroendocrine tumor (G-NET) and common-type gastric adenocarcinoma treated in the same study period were identified to compare the endoscopic findings between each G-NEC versus G-NET, and G-NEC versus common-type gastric adenocarcinoma. Patients with common-type gastric adenocarcinoma were matched for age, sex, tumor size, and depth of tumor invasion in 1:3 ratio. RESULTS Among 15 patients with 15 G-NECs, submucosal tumor-like marginal elevation (87%), adherent white coat (67%), and ulceration with a distinct border (60%) were characteristic endoscopic findings in white-light images. Magnifying narrow-band imaging endoscopy revealed an absent microsurface (MS) pattern plus disrupted irregular microvessel (MV) in five (71%) of seven cases with evaluable MS and MV patterns. The area with an absent MS pattern plus disrupted irregular MV corresponded to the histological finding of NEC component in all five cases. These endoscopic features were all significantly more frequent in G-NECs than G-NETs (n = 22) or common-type gastric adenocarcinomas (n = 45). CONCLUSIONS These endoscopic features should be taken into consideration to increase the index of suspicion and to improve the accuracy of target biopsies for G-NEC.

Abstract
Chemoradiotherapy (CRT) and radiotherapy (RT) are treatment options for esophageal squamous cell carcinoma (ESCC), but local residual/recurrent cancer after CRT/RT is a major problem. Endoscopic resection (ER) is an effective treatment option for local residual/recurrent cancer. To ensure the efficacy of ER, complete removal of endoscopically visible lesions with cancer-free vertical margins is desired. This study aimed to identify the endoscopic parameters associated with the complete endoscopic removal of local residual/recurrent cancer. In this single-center, retrospective study, we used a prospectively maintained database to identify esophageal lesions that were diagnosed as local residual/recurrent cancer after CRT/RT and treated by ER between January 2012 and December 2019. We evaluated the associations of endoscopic R0 resection with findings on conventional endoscopy and endoscopic ultrasonography (EUS). In total, 98 lesions (83 cases) were identified from our database. The rate of endoscopic R0 resection was higher for flat lesions (100% versus 77%, P = 0.00014). EUS was performed for 24 non-flat lesions, and endoscopic R0 resection was achieved for 94% of lesions with an uninterrupted fifth layer. Flat lesions on conventional endoscopy and lesions with an uninterrupted fifth layer on EUS are good candidates for ER.

Abstract
BACKGROUND Several pre-clinical studies have reported the usefulness of artificial intelligence (AI) systems in the diagnosis of esophageal squamous cell carcinoma (ESCC). We conducted this study to evaluate the usefulness of an AI system for real-time diagnosis of ESCC in a clinical setting. METHODS This study followed a single-center prospective single-arm non-inferiority design. Patients at high risk for ESCC were recruited and real-time diagnosis by the AI system was compared with that of endoscopists for lesions suspected to be ESCC. The primary outcomes were the diagnostic accuracy of the AI system and endoscopists. The secondary outcomes were sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and adverse events. RESULTS A total of 237 lesions were evaluated. The accuracy, sensitivity, and specificity of the AI system were 80.6%, 68.2%, and 83.4%, respectively. The accuracy, sensitivity, and specificity of endoscopists were 85.7%, 61.4%, and 91.2%, respectively. The difference between the accuracy of the AI system and that of the endoscopists was - 5.1%, and the lower limit of the 90% confidence interval was less than the non-inferiority margin. CONCLUSIONS The non-inferiority of the AI system in comparison with endoscopists in the real-time diagnosis of ESCC in a clinical setting was not proven.

Abstract
BACKGROUND AND AIM As more superficial esophageal cancer (EC) patients are being treated with endoscopic resection (ER), it is important to understand the outcomes, including survival data, of patients who develop metachronous EC and head and neck cancer (HNC). We aimed to evaluate the long-term surveillance and survival outcomes of metachronous EC and HNC after esophageal ER. METHODS This study included 627 patients who underwent ER of superficial esophageal squamous cell carcinoma from 2008 to 2016 and were generally followed by annual or biannual esophagogastroduodenoscopy up to 2019 at Osaka International Cancer Institute. Data on metachronous cancer development and causes of death were collected from an integrated database of hospital-based cancer registry and Vital Statistics of Japan. RESULTS During a median (range) follow-up period of 67.4 (3.8-142.7) months, 230 patients (36.7%) developed 500 metachronous ECs and 126 patients (20.1%) developed 239 metachronous HNCs, post-ER of index EC. The 3-year, 5-year, and 7-year cumulative incidences were 25.8%, 36.0%, and 43.6% for metachronous EC and 10.9%, 16.0%, and 26.9% for metachronous HNC, respectively. No patients died of metachronous EC, and only seven patients (1.1%) died of metachronous HNC. The 3-year, 5-year, and 7-year disease-specific survival rates were 99.8%, 99.6%, and 98.6%, respectively. CONCLUSIONS The incidences of metachronous EC and HNC increase with time over 5 years after esophageal ER; therefore, surveillance endoscopy should be continued over 5 years. Endoscopic surveillance is useful for survivors after esophageal ER given the high incidence and extremely low mortality of metachronous EC and HNC.

Abstract
BACKGROUND AND AIM Hematochezia is a major adverse event associated with colorectal endoscopic submucosal dissection (ESD). This study aimed to distinguish between hematochezia that required endoscopic hemostasis and hematochezia that required no hemostasis. METHODS This retrospective study included consecutive patients who underwent ESD for colorectal tumors at the Osaka International Cancer Institute between September 2017 and August 2020. The exclusion criteria were as follows: patients with coexisting advanced colorectal cancers or inflammatory bowel diseases, patients who received incomplete ESD or emergency surgery, or patients who underwent ESD for multiple lesions. We evaluated whether the patients had hematochezia and underwent emergency colonoscopy and hemostasis during hospitalization. The degree of hematochezia in the saved photographs was assessed using the hematochezia scale and classified as mild, moderate, or severe. Blood pressure, heart rate, time from ESD to first hematochezia, and total number of hematochezia episodes were also evaluated. RESULTS Among the 437 patients who underwent ESD, 44 were excluded, and 393 patients were evaluated. Hematochezia was observed in 100 patients (25%). Emergency colonoscopy was performed in 12 patients (3%), and hemostasis was required in six patients (2%). For patients with hematochezia, only mild hematochezia and hematochezia that developed ≤ 48 h after ESD were significantly associated with no intervention for hemostasis. The positive predictive value for no intervention for hemostasis was 100% (93-100%) for mild hematochezia and 98% (93-100%) for hematochezia ≤ 48 h. CONCLUSIONS Mild hematochezia and hematochezia ≤ 48 h were negative predictors of hemostasis, in which emergency colonoscopy may be avoided.

Abstract
BACKGROUND Inactivated alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) are related to esophageal carcinogenesis. We aimed to clarify the clinical features associated with the alcohol-degrading enzyme genotypes, ADH1B and ALDH2. We also investigated the risk factors for metachronous esophageal squamous cell carcinoma (ESCC) and head and neck SCC (HNSCC). METHODS We conducted a single-center, retrospective study including patients with ESCC treated by endoscopic resection. Patients were recruited between October 2020 and September 2021. Buccal mucosal swabs were obtained from them to analyze the genetic polymorphisms affecting ADH (ADH1B) and ALDH (ALDH2) activity. Patients were categorized into three groups: both inactivated = double-inactivated group; inactivated ADH1B or ALDH2 = single-inactivated group; and both activated = activated group. RESULTS Among the 297 enrolled patients, patients in the double-inactivated group were significantly younger (P < 0.001) and 60% of them were ≤ 50 years old. This group also had more ESCCs located in the upper esophagus (P < 0.001) and more simultaneous multiple ESCCs (P = 0.044). More than half of the patients had multiple Lugol-voiding lesions (LVLs) (P < 0.001) and heavy alcohol consumers (P = 0.012). Metachronous ESCC and HNSCC were more common in the double-inactivated group (P < 0.001, P = 0.001). Multivariate analysis identified located in the upper esophagus, multiple LVLs and history of HNSCC as risk factors for metachronous ESCC. CONCLUSIONS Activation patterns of alcohol-metabolizing enzymes were related to age at ESCC onset, lesion location, and metachronous ESCC and HNSCC. Different approaches to the prophylaxis and treatment of esophageal cancer should be considered, depending on the enzyme activity pattern.

Abstract
OBJECTIVES Endoscopic resection (ER) is a minimally invasive treatment for esophageal squamous cell carcinoma (ESCC). However, stricture may develop after ER for widespread lesions. Application of ER is justified if these cancers are pathological T1a-epithelial/lamina propria (pEP/LPM) cancers that can be cured by ER. We conducted a study to clarify the association between pathological invasion depth and lesion size or circumference in clinical (c) EP/LPM cancers. METHODS From our database, we identified patients diagnosed with cEP/LPM ESCC via endoscopic examination who underwent endoscopic or surgical tumor resection. The accuracy of the cEP/LPM ESCC diagnosis was determined by histologically diagnosing cancer invasion depth as a reference standard. RESULTS Between January 2015 and December 2019, 1271 cancer patients were diagnosed with cEP/LPM ESCC, of which 1195 (94.0%) were correctly diagnosed with pEP/LPM cancer. The positive predictive value (PPV) classified according to lesion sizes of ≤25, 26-49, and ≥50 mm was 95.8% (981/1024 lesions), 89.7% (191/213 lesions), and 67.6% (23/34 lesions), respectively. PPV according to the circumferential extent of <3/4, ≥3/4, and <1, and whole was 94.6% (1164/1230 lesions), 75.0% (24/32 lesions), and 77.8% (7/9 lesions), respectively. In multivariate analysis, the PPV of cEP/LPM ESCC was significantly associated with lesion size (P < 0.001) and male sex. CONCLUSIONS Between January 2015 and December 2019, 1271 cancer patients were diagnosed with cEP/LPM ESCC, of which 1195 (94.0%) were correctly diagnosed with pEP/LPM cancer. The PPV of cEP/LPM ESCC was related to lesion size. Treatment should be determined considering the high risk of cancer invasion into the muscularis mucosa or deeper in cEP/LPM cancers with a lesion size of ≥50 mm.

Abstract
BACKGROUND AND AIM A multicenter randomized controlled trial reported a better R0 resection rate for intermediate-sized (10-20 mm) colorectal polyps with underwater endoscopic mucosal resection (UEMR) than conventional endoscopic mucosal resection (CEMR). To clarify whether UEMR removes enough submucosal tissue in the removal of unpredictable invasive cancers, we investigated the cutting plane depth with UEMR versus CEMR. METHODS This was a post-hoc analysis of a randomized controlled trial in which 210 intermediate-sized colorectal polyps were removed in five Japanese hospitals. One pathologist and two gastroenterologists independently reviewed all resected specimens and measured the cutting plane depth. The cutting plane depth was evaluated as (i) maximum depth of submucosal layer and (ii) mean depth of submucosal layer, calculated using a virtual pathology system. RESULTS We identified 168 appropriate specimens for the evaluation of the cutting plane depth, resected by UEMR (n = 88) and CEMR (n = 80). The median resection depth was not significantly different between UEMR and CEMR specimens, regardless of the measurement method ([i] 1317 vs 1290 μm, P = 0.52; [ii] 619 vs 545 μm, P = 0.32). All specimens in the UEMR and CEMR groups contained substantial submucosa and no muscularis propria. CONCLUSIONS The cutting plane depth with UEMR was comparable with that with CEMR. UEMR can be a viable alternative method that adequately resects the submucosal layer for the histopathological assessment of unpredictable submucosal invasive cancers.

Abstract
BACKGROUND The optimal radiation dose for treating non-metastatic superficial esophageal squamous cell carcinoma is unknown. In this retrospective observational study, we investigated the influence of radiation dose and pretreatment endoscopic prediction of tumor invasion depth on local recurrence after definitive chemoradiotherapy in patients with superficial esophageal squamous cell carcinoma. METHODS We analyzed 134 patients with clinical Tis-T1N0M0 esophageal squamous cell carcinoma who underwent chemoradiotherapy at our institution between 2006 and 2019. Patients were grouped into standard-dose (50.0-50.4 Gy) and high-dose (60.0 Gy) radiotherapy groups. The outcomes of interest were local recurrence and major local recurrence (endoscopically unresectable local recurrent tumors). Kaplan-Meier analysis and the log-rank test were used with propensity score and inverse probability of treatment weighting. Cox proportional hazards analysis was performed to identify predictors of local recurrence and major local recurrence. RESULTS The median follow-up times were 52 and 84 months for the standard-dose and high-dose groups, respectively. The adjusted 3-year local recurrence and major local recurrence rates in the standard-dose and high-dose groups were 33.8 and 9.6% (adjusted hazard ratio, 4.00 [95% confidence interval: 1.64-9.73]; adjusted log-rank p = 0.001) and 12.5 and 4.7% (adjusted hazard ratio, 3.13 [95% confidence interval: 0.91-10.81]; adjusted log-rank p = 0.098), respectively. Cox proportional hazards analysis showed that standard-dose radiotherapy and endoscopic findings of deep submucosal invasion are independently associated with local recurrence and major local recurrence. CONCLUSIONS High-dose radiotherapy is more beneficial for local tumor control than standard-dose radiotherapy in patients with non-metastatic superficial esophageal squamous cell carcinoma. The use of high-dose radiotherapy may merit consideration for tumors with deep submucosal invasion.

Abstract
Effective control of severe immune-related adverse events, including cytokine release syndrome (CRS), is essential for the success of immunotherapy. We present a case of a granulocyte colony-stimulating factor–producing pleomorphic lung carcinoma treated with nivolumab plus ipilimumab which developed CRS and severe immune-related pneumonitis. The effect of immunotherapy was heterogeneous; gastric metastasis was eliminated, but the pulmonary lesion had primary resistance. Steroid and tocilizumab were successful in controlling CRS, but additional infliximab was necessary to control pneumonitis. To control immune-related adverse events, it is important to choose immunosuppressive agents to the specific target organ and inflammatory cells.

Abstract
Cold snare polypectomy (CSP; polypectomy without electrocautery) has spread rapidly worldwide during the past decade in what has been called "Cold Revolution". We performed a PubMed literature search for studies investigating CSP outcomes for colorectal polyps. Five randomized controlled trials (RCTs) assessed the complete resection rates (CRRs). The CRRs were similar regardless of the presence or absence of electrocautery, and the efficacy of submucosal injection for better CRRs is still controversial. Eight RCTs assessed the adverse events. The incidence of intraprocedural bleeding with cold procedures was comparable to or higher than that of hot procedures. The incidences of delayed bleeding were comparable to or lower with cold procedures, especially in patients taking anticoagulants. Fifteen studies have been reported on CSP for large (≥1 cm) colorectal polyps (10 retrospective studies, four prospective single-arm studies, and one prospective RCT). These studies reported that the safe cold procedures (a low intra- and post-procedural bleeding rate without perforation) could be implemented for lesions ≥1 cm. However, considering the incision depth of CSP and the local recurrence rate based on the current evidence, only large sessile serrated lesions (SSLs) can be candidates for cold procedures, and large adenomas should not be candidates for this procedure. Based on the current evidence, CSP seems to be the appropriate standard procedure for sub-centimeter colorectal low-grade adenomas due to its safety and simplicity. Thus, large SSLs can be candidates for cold procedures; however, careful inspection and further prospective studies are warranted to confirm the procedure's clinical relevance.

Abstract
BACKGROUND AND AIM The long-term outcomes of endoscopic resection for nonampullary duodenal neuroendocrine tumors are limited. We aimed to clarify it. METHODS Consecutive patients with nonampullary duodenal neuroendocrine tumors endoscopically treated at our institute between January 2005 and June 2020 were included in this retrospective study. En bloc and R0 resection rates and adverse events were evaluated as short-term outcomes of endoscopic resection. The 5-year overall and recurrence-free survival rates of patients after endoscopic resection were calculated as long-term outcomes. RESULTS Of 34 patients with 34 lesions, 33 patients (97%) underwent endoscopic mucosal resection, and one (3%) underwent endoscopic submucosal dissection. En bloc resection was achieved in 33 lesions (97%). R0 resection was achieved in 20 lesions (59%). The median tumor size was 6 mm (range: 3-13). Thirty-one lesions (91%) and three lesions (9%) were classified as G1 and G2, respectively. Lymphovascular invasion was observed in six lesions (18%). Intraprocedural perforation occurred in four patients (12%) who were conservatively treated with endoscopic closure. All 34 patients were followed up without additional treatment after endoscopic resection, and no recurrence or metastasis developed during the median follow-up period of 47.9 months (range: 9.0-187.1). The 5-year overall survival and recurrence-free survival rates were 87.1% and 100%, respectively. CONCLUSIONS Endoscopic resection provided a favorable long-term prognosis for patients with nonampullary duodenal neuroendocrine tumors without lymph node metastasis.

Abstract
OBJECTIVES Artificial intelligence (AI) systems have shown favorable performance in the detection of esophageal squamous cell carcinoma (ESCC). However, previous studies were limited by the quality of their validation methods. In this study, we evaluated the performance of an AI system with videos simulating situations in which ESCC has been overlooked. METHODS We used 17,336 images from 1376 superficial ESCCs and 1461 images from 196 noncancerous and normal esophagi to construct the AI system. To record validation videos, the endoscope was passed through the esophagus at a constant speed without focusing on the lesion to simulate situations in which ESCC has been missed. Validation videos were evaluated by the AI system and 21 endoscopists. RESULTS We prepared 100 video datasets, including 50 superficial ESCCs, 22 noncancerous lesions, and 28 normal esophagi. The AI system had sensitivity of 85.7% (54 of 63 ESCCs) and specificity of 40%. Initial evaluation by endoscopists conducted with plain video (without AI support) had average sensitivity of 75.0% (47.3 of 63 ESCC) and specificity of 91.4%. Subsequent evaluation by endoscopists was conducted with AI assistance, which improved their sensitivity to 77.7% (P = 0.00696) without changing their specificity (91.6%, P = 0.756). CONCLUSIONS Our AI system had high sensitivity for the detection of ESCC. As a support tool, the system has the potential to enhance detection of ESCC without reducing specificity. (UMIN000039645).

Abstract
BACKGROUND Lugol chromoendoscopy has been conventionally used for the detection and delineation of esophageal squamous cell carcinoma (SCC). However, the boundaries of some lesions are unclear even with Lugol chromoendoscopy, and there is a risk of residual lesions or over-excision. This study aimed to evaluate the utility of narrow-band imaging (NBI) for the delineation of esophageal SCC in endoscopic resection. METHODS Among 367 esophageal SCCs endoscopically resected between January and December 2019 at our institute, this retrospective study included consecutive lesions, which were first marked with NBI, followed by Lugol chromoendoscopy. The proportion of residual cancer, which was defined as histologically proven cancer confirmed adjacent to the scar within 1 year after endoscopic resection, was evaluated. To evaluate whether the marks added by Lugol chromoendoscopy after NBI marking were more reliable, we evaluated the presence of cancer in the iodine-unstained area outside the NBI-determined marks, i.e., the cancerous area missed by NBI. The presence of cancer in the iodine-stained areas inside the NBI-determined marks, i.e., the cancerous area missed by Lugol, was also evaluated. These were compared to assess the risk of residual cancer in endoscopic resection with NBI and Lugol chromoendoscopy. RESULTS Among 304 lesions, 2 (0.7%) residual cancers were detected. The cancerous area missed by NBI and the cancerous area missed by Lugol were identified in 18 (6%) and 43 (14%) lesions, respectively (P = 0.001). CONCLUSIONS NBI might be acceptable for delineating the extent of esophageal SCCs that are difficult to delineate with Lugol chromoendoscopy.

Abstract
BACKGROUND AND AIM Occasionally, colorectal tumors without characteristics of deep submucosal invasion are found to be invasive upon pathological evaluation after endoscopic resection (ER). Because the resection depth for underwater endoscopic mucosal resection (UEMR) has not been clarified, we evaluated the feasibility of UEMR for pathologically invasive colorectal cancer (pT1-CRC). METHODS We retrospectively investigated data on the backgrounds and outcomes of patients with pT1-CRC who underwent UEMR between January 2014 and June 2019 at our institute. As a reference standard, the backgrounds and outcomes of pT1-CRCs that had undergone conventional EMR (CEMR) were also investigated. RESULTS Thirty-one patients (median age, 68 years [range, 32-88 years]; 22 men [71%]) were treated with UEMR. Median lesion size was 17 mm (range, 6-50 mm). The endoscopic complete resection rate was 100%. The overall en bloc resection rate was 77%, and the VM0, HM0, and R0 resection rates were 81%, 58%, and 55%, respectively. In cases of pT1a (invasion <1000 μm)-CRC (n = 14), the en bloc, VM0, and R0 resection rates were 92%, 100%, and 71%, respectively. Seventeen patients (five with risk factors for lymph node metastasis and 12 without) were followed up, and no local recurrence and distant metastasis were observed during the follow-up period (median follow-up period, 18 months [range, 6-62 months]) after UEMR. The outcomes of UEMR seemed to be comparable with those of CEMR (n = 32). CONCLUSIONS The VM0 rate of UEMR for pT1-CRC, especially for pT1a-CRC, without characteristics of deep submucosal invasion seems feasible.

Abstract
Objective The rare incidence of submucosal invasive non-ampullary duodenal carcinoma has led to scant information in literature; therefore, we compared the clinicopathological features between submucosal invasive carcinoma (SM-Ca), mucosal carcinoma (M-Ca), and advanced carcinoma (Ad-Ca). Materials We retrospectively analyzed 165 patients with sporadic non-ampullary duodenal carcinomas (SNADCs) from four institutions between January 2003 and December 2018. The SNADCs were divided to three groups according to histological diagnosis: SM-Ca, M-Ca, and Ad-Ca. The clinicopathological characteristics and mucin phenotypes were compared between groups. Results Among the 165 SNADCs, 11 (7%) were classified as SM-Ca, 70 (42%) as M-Ca, and 84 (51%) as Ad-Ca. We found that all SM-Ca (P = 0.013) and most Ad-Ca (P = 0.020) lesions were located on the oral-Vater; however, an almost equal distribution of M-Ca lesions was found between the oral- and anal-Vater. No significant difference was observed between the tumor diameter of M-Ca and SM-Ca; however, 45% (5/11) of SM-Ca were ≤10 mm. A total of 73% (8/11) of SM-Ca were classified as gastric phenotype and no lesions were classified as intestinal phenotype; whereas most M-Ca were classified as intestinal phenotype (67%, 8/12). Conclusions SM-Ca lesions were all located on the oral-Vater and were highly associated with the gastric mucin phenotype, which were different from the features of most M-Ca.

Abstract
BACKGROUND AND AIM The incidence of identified superficial non-ampullary duodenal epithelial tumors (SNADETs) has been increasing with recent advances in endoscopic diagnosis. Nevertheless, the clinical features of SNADETs with malignant potential remain unclear. The aim of the present study was to clarify the clinical characteristics of high-grade SNADETs. METHODS A total of 328 SNADETs that had been endoscopically or surgically resected between January 2013 and April 2019 were identified from an endoscopic and pathological database. Clinical characteristics were compared between mucosal low-grade neoplasm (n = 154) and mucosal high-grade neoplasm/submucosal carcinoma (HGN/SMC, n = 174). RESULTS In univariate analysis, tumor size, pre-ampullary tumor location, red color, and rough/nodular surface were significantly associated with HGN/SMC. In multivariate analysis (odds ratio [95% confidence interval]), large (≥10 mm) tumor size (odds ratio: 4.5, 95% confidence interval: 2.6-7.7, P < 0.001) and pre-ampullary tumor location (odds ratio: 2.1, 95% confidence interval: 1.3-3.5, P = 0.004) were independent predictors for HGN/SMC. Analysis of histological phenotypes revealed that the proportion of tumors that were HGN/SMC was much greater for gastric-type tumors (21/23 lesions, 91%) than for intestinal-type tumors (150/302 lesions, 50%) (P < 0.001) and that all gastric-type tumors were located in the pre-ampullary portion. CONCLUSIONS Pre-ampullary location and large tumor size are independent predictors for HGN/SMC SNADETs. Pre-ampullary tumor location is significantly associated with gastric histological phenotype. These findings may help in decision making for endoscopic treatment, active indication for pre-ampullary tumor or tumor ≥10 mm, and understanding the pathophysiology of SNADETs.

Abstract
OBJECTIVES We aimed to develop an artificial intelligence (AI) system for the real-time diagnosis of pharyngeal cancers. METHODS Endoscopic video images and still images of pharyngeal cancer treated in our facility were collected. A total of 4559 images of pathologically proven pharyngeal cancer (1243 using white light imaging and 3316 using narrow-band imaging/blue laser imaging) from 276 patients were used as a training dataset. The AI system used a convolutional neural network (CNN) model typical of the type used to analyze visual imagery. Supervised learning was used to train the CNN. The AI system was evaluated using an independent validation dataset of 25 video images of pharyngeal cancer and 36 video images of normal pharynx taken at our hospital. RESULTS The AI system diagnosed 23/25 (92%) pharyngeal cancers as cancers and 17/36 (47%) non-cancers as non-cancers. The transaction speed of the AI system was 0.03 s per image, which meets the required speed for real-time diagnosis. The sensitivity, specificity, and accuracy for the detection of cancer were 92%, 47%, and 66% respectively. CONCLUSIONS Our single-institution study showed that our AI system for diagnosing cancers of the pharyngeal region had promising performance with high sensitivity and acceptable specificity. Further training and improvement of the system are required with a larger dataset including multiple centers.

Abstract
The association between severe adverse events (SAEs) and prior radiotherapy or stent type remains controversial. Patients with esophageal or esophagogastric junctional cancer who underwent stent placement (2005–2019) were enrolled in this retrospective study conducted at a tertiary cancer institute in Japan. The exclusion criteria were follow-up period of < 1 month and insufficient data on stent type or cancer characteristics. We used Mann–Whitney’s U test for quantitative data and Fisher’s exact test for categorical data. Multivariate analysis was performed using a logistic regression model. 107 stents were placed. Low radial-force stents (L group) were used in 51 procedures and high radial-force stents (H group) in 56 procedures. SAEs developed after nine procedures, the median interval from stent placement being 6 days (range, 1–141 days). SAEs occurred more frequently in the H (14%: 8/56) than in the L group (2%: 1/51) (P = 0.03). In patients who had undergone prior radiotherapy, SAEs were more frequent in the H (36%: 4/11) than in the L group (0%: 0/13) (P = 0.03). Re-obstruction and migration occurred after 16 and three procedures, respectively; these rates did not differ significantly between groups (P = 0.59, P = 1, respectively). Low radial-force stents may reduce the risk of SAEs after esophageal stenting.

Abstract
Endoscopic resection (ER) is the mainstay of treatment for superficial esophageal squamous cell carcinoma (SESCC) instead of esophagectomy because of its minimal invasiveness and favorable clinical outcomes. Developments in endoscopic submucosal dissection have enabled en bloc resection of SESCCs regardless of size, thus reducing the risk of local recurrence. Although ER for SESCC is effective, metastasis may subsequently occur. Additionally, extensive esophageal ER confers a risk of postoperative esophageal stricture. Therefore, accurate assessment of the invasion depth and circumferential extent of SESCCs is important in determining the indications for ER. Diagnostic accuracies for SESCC invasion differ between epithelial (EP)/lamina propria (LPM), muscularis mucosa (MM)/submucosal (SM1), and SM2 cancers. ER is strongly indicated for clinically diagnosed (c)EP/LPM cancers because 90% of these are as pathologically diagnosed (p)EP/LPM, which has a very low risk of metastasis. Remarkably, the diagnostic accuracy for cMM/SM1 differs significantly with lateral spread of cancer. Eighty percent of cMM/SM1 cancers with ≤3/4 circumferential spread prove to be pEP/LPM or pMM/SM1, which have very low or low risk of metastasis. Thus, these are adequate candidates for ER. However, given the relatively low proportion of pEP/LPM or pMM/SM1 and high risk of subsequent stricture, ER is not recommended for whole circumferential cMM/SM1 cancers. For cMM/SM1 cancers that involve >3/4 but not the whole circumference, ER should be considered on a lesion-by-lesion basis because the risk of post-ER stricture is not very high, but the proportion of pEP/LPM or pMM/SM1 is relatively low. ER is contraindicated for cSM2 cancers because 75% of them are pSM2, which has high risk of metastasis.

Abstract
BACKGROUND Although optimal treatment of superficial esophageal squamous cell carcinoma (SCC) requires accurate evaluation of cancer invasion depth, the current process is rather subjective and may vary by observer. We, therefore, aimed to develop an AI system to calculate cancer invasion depth. METHODS We gathered and selected 23,977 images (6857 WLI and 17,120 NBI/BLI images) of pathologically proven superficial esophageal SCC from endoscopic videos and still images of superficial esophageal SCC taken in our facility, to use as a learning dataset. We annotated the images with information [such as magnified endoscopy (ME) or non-ME, pEP-LPM, pMM, pSM1, and pSM2-3 cancers] based on pathologic diagnosis of the resected specimens. We created a model using a convolutional neural network. Performance of the AI system was compared with that of invited experts who used the same validation video set, independent of the learning dataset. RESULTS Accuracy, sensitivity, and specificity with non-magnified endoscopy (ME) were 87%, 50%, and 99% for the AI system and 85%, 45%, 97% for the experts. Accuracy, sensitivity, and specificity with ME were 89%, 71%, and 95% for the AI system and 84%, 42%, 97% for the experts. CONCLUSIONS Most diagnostic parameters were higher when done by the AI system than by the experts. These results suggest that our AI system could potentially provide useful support during endoscopies.

Abstract
OBJECTIVE Flow cytometry has not been widely used in routine clinical practice for the diagnosis of gastrointestinal lymphoma; this is mainly because of the absence of an appropriate protocol. Here, we established a protocol for flow cytometric analysis of a single biopsy specimen from the gastrointestinal mucosa and investigated its sensitivity and specificity. DESIGN In this prospective study, we enrolled patients with previously diagnosed gastrointestinal lymphoma and patients with gastrointestinal lesions that were suspected to be lymphoma. RESULTS Overall, 15 patients with gastric extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (N=8), duodenal follicular lymphoma (grade 1; N=5), and benign lymphoid hyperplasia (ileum, N=1, and rectum, N=1) were included in this study. Of these, lymphocytes were isolated from 14 patients (93.3%). There were 200,000-1,500,000 viable cells per patient. Biopsy specimens from 10 out of the 12 patients with lymphoma were positive for light chain restriction; the two patients with benign lymphoid hyperplasia showed negative results. CONCLUSIONS An adequate number of lymphocytes for flow cytometry could be isolated from a single specimen of endoscopic mucosal biopsy from 93.3% of the patients. Overall, the sensitivity of flow cytometric analysis of light chain expression for the diagnosis of B-cell lymphoma was 83.3%, and the specificity was 100%. Although further investigation is required as the sample size of the present study was small, our study suggests a potential option for diagnosing B-cell lymphoma in the gastrointestinal mucosa.

Abstract
Bone metastasis during the early stages of gastric cancer is rare, and synchronous bone metastasis is even less common. The present report outlines a case of a small early gastric cancer, which was detected due to bone metastasis. A 63-year-old man was referred to Fukuyama Medical Center with back pain and anorexia of 2 weeks' evolution. MRI revealed multiple metastatic lesions in the thoracic and spinal bone. Fluorodeoxyglucose positron emission tomography revealed focal uptake in the lesser curvature of the stomach and in the spinal bone, pelvic and thigh bone, but uptake was not detected in the stomach. Esophagogastroduodenoscopy revealed a 10 mm slightly elevated lesion with a central depression in the middle-third of the stomach. Endoscopic ultrasonography confirmed that the tumor was confined to the mucosa. A biopsy specimen acquired from the gastric lesion indicated signet-ring cell carcinoma, and the specimen acquired from the lumbar spine revealed cell aggregation such as that found in signet-ring cell carcinoma. The patient received first-line chemotherapy with S-1 and cisplatin, and second-line chemotherapy with nab-paclitaxel. However, the patient died 120 days after consultation at Fukuyama Medical Center.

Abstract
OBJECTIVE Gastrointestinal tract lymphomas are currently detected more frequently due to advances in endoscopic technology. The aim of this study was to assess the feasibility of flow cytometric analysis of restricted light chain in endoscopic biopsy specimens for the diagnosis of gastrointestinal tract B-cell lymphoma. We prepared viable cell suspensions from unfixed specimens obtained from 10 consecutive patients who had a previous histological diagnosis of gastrointestinal tract B-cell lymphoma. We performed immunophenotypic studies with multi-color flow cytometry and assessed clonality through examination of immunoglobulin light chain expression exclusively in a population identified by anti-CD45 or CD20 antibodies. RESULTS We could perform light chain expression analysis with 2 endoscopic biopsy specimens from all 10 patients with gastrointestinal tract B-cell lymphoma. We conclude that flow cytometric analysis of endoscopic biopsy specimens is feasible and thus likely useful for the diagnosis of gastrointestinal tract B-cell lymphoma in clinical settings.

BACKGROUND AND AIM Although sporadic non-ampullary duodenal adenoma is speculated to be precancerous lesion, the relationship between adenoma and carcinoma remains unclear due to their rarity. Previous studies on sporadic non-ampullary duodenal epithelial neoplasm (SNADEN) have mainly targeted superficial tumors, like adenoma and early carcinoma. The clinicopathological features, including those of advanced carcinoma, remain poorly investigated. We assessed the clinicopathological features of SNADEN, including advanced carcinoma, focusing on tumor location. METHODS We retrospectively collected the data of 410 patients who had been clinically and pathologically diagnosed with SNADEN at 11 institutions in Japan between June 2002 and March 2014. RESULTS The SNADEN was mucosal neoplasia and invasive carcinoma in 321 (78.3%) and 89 (21.7%) patients, respectively. The proportion of invasive carcinomas in SNADEN was significantly higher on the oral side of the papilla of Vater (oral-Vater) than on the anal side (anal-Vater) (27.9% vs 14.4%, P < 0.001). Undifferentiated-type carcinoma was significantly more frequent with oral-Vater than anal-Vater (38.7% vs 14.8%, P = 0.026). The recurrence rate of surgically R0 resected locally advanced carcinomas was significantly higher with oral-Vater than anal-Vater (46.4% vs 8.3%, P = 0.021). Furthermore, the relapse-free survival with oral-Vater was significantly shorter than with anal-Vater (hazard ratio: 2.35; 95% confidence interval: 1.09-5.50; P = 0.028). CONCLUSIONS The clinicopathological features of SNADEN on oral-Vater were different from those on anal-Vater. SNADEN on oral-Vater was more likely to be invasive carcinomas and might behave more aggressively due to biologically higher malignancy than that on anal-Vater.

Abstract
A 1-year-old female toddler who was under a great amount of psychological stress presented with acute hematemesis. She had no significant medical history; she displayed lethargy and was anemic. Although blood transfusion and famotidine were administered for upper gastrointestinal bleeding (UGIB), the anemia did not improve. Thus, early endoscopy was performed under general anesthesia, revealing a gastric ulcer with exposed vessels in the supra-angular region. Cauterization via bipolar hemostatic forceps was performed on the exposed vessels, and the bleeding was controlled successfully. We diagnosed the patient with hemorrhagic stress-induced gastric ulcer due to psychological stress. Three months later, endoscopy revealed that the gastric ulcer had healed.

Abstract
This case report refers to a 31-year-old patient with an 11-year history of Crohn's disease. The patient presented with an edematous elevated lesion in the splenic flexure. Two histological analyses revealed no signs of obvious dysplasia, and the patient subsequently began infliximab treatment. Nine months later, a worsening of the stricture of the edematous elevated lesion was observed in the splenic flexure, and transverse colonic resection was performed. A histological investigation of the lesion in the splenic flexure revealed advanced adenocarcinoma. Six months after the surgery, computed tomography revealed recurrent carcinoma and peritoneal metastases. The patient was administered palliative chemotherapy.

Abstract
Mantle cell lymphoma (MCL) is a malignant lymphoma of the gastrointestinal tract that mostly presents as multiple lymphomatous polyposis (MLP); however, MLP with intussusception is rarely reported in MCL. Furthermore, a single protruding lesion with intussusception has never been reported in primary small intestinal MCL. A 70-year-old man presented with pain in the right lower abdomen. Computed tomography and colonoscopy revealed ileocecal intussusception. Ileocecal resection was performed. Histology and immunohistochemistry of the resected specimen showed MCL with a single protruding lesion. The patient was successfully treated with surgery alone and remains in complete remission at the three-year follow-up.

Abstract
Mucosa-associated lymphoid tissue (MALT) lymphoma and reactive inflammatory lymphoid changes are frequently difficult to distinguish based on a routine histological differential diagnosis. We were unable to diagnose gastric MALT lymphoma histologically using specimens obtained by endoscopy, although a flow cytometry (FCM) analysis demonstrated clonality of neoplastic cells by separating cells by CD45 gating. Furthermore, a fluorescence in situ hybridization (FISH) analysis showed trisomy 18. We therefore diagnosed gastric MALT lymphoma with trisomy 18. We recommend that FCM and FISH analyses of biopsy specimens be considered for diagnosing gastric MALT lymphoma if this diagnosis is suspected based on endoscopic findings.

Abstract
A 45-year-old man presented with a 24-mm macrocystic lesion at the pancreatic head, which was detected by computed tomography (CT). During six years of follow-up, CT, MRI, and endosonographic images of the cystic lesion showed that the cystic lesion had enlarged to 42mm, with the appearance of a thick cyst wall. Since a cystic tumor could not be ruled out, surgery was performed. Pathological examination of the resected specimen revealed microcystic-type serous cystadenoma of the pancreas, with the presence of internal bleeding in the cyst and hemorrhage and thick fibrous tissue in the cyst wall. We could observe a serous cystic neoplasm with prismatic form changes on an image obtained during long-term follow-up. Thus, we considered this case to be useful for investigating the natural history of serous cystic neoplasm of the pancreas.

Abstract
Case 1 was a 70-year-old man, and case 2 was a 65-year-old woman. Both were diagnosed with type 2 advanced HER2-positive gastric cancer. Capecitabine, cisplatin, and trastuzumab (HXP therapy) were administered to both patients. However, both patients developed peritonitis caused by gastric cancer perforation during HXP therapy on day 38 for case 1 and day 8 for case 2. Emergency omentum filling and gastric segmental resection were performed for both patients. The same chemotherapy regimen was continued after the surgery, and partial response was observed in both patients. Because most advanced HER2-positive gastric cancers are ulcers, we should always consider the risk of gastric cancer perforation while administering HXP therapy, which has a high cytoreductive effect. Good convalescence can be expected by continuing chemotherapy after emergency surgery due to gastric cancer perforation.

Abstract
BACKGROUND Previous studies showed that 5 μg of ramosetron, a serotonin (5-hydroxytryptamine: 5-HT)-3 receptor antagonist, is only effective in male patients with irritable bowel syndrome (IBS) with diarrhea (IBS-D). We hypothesized that either dose 1.25, 2.5, or 5 μg of ramosetron would be effective in female patients with IBS-D. METHODS This randomized, double-blind, placebo-controlled, phase II dose-finding exploratory trial included 409 female outpatients with IBS-D treated in Japan. They were administered oral placebo (n=102), or 1.25 μg (n=104), 2.5 μg (n=104), or 5 μg (n=99) of ramosetron once daily for 12 weeks after a 1-week baseline period. The primary endpoint was monthly responder rates of global improvement of IBS symptoms in the first month. Secondary endpoints included global improvement in the other months, abdominal pain/discomfort, weekly mean changes in the Bristol Stool Form Scale (BSFS), and IBS-QOL. KEY RESULTS Middle dose (2.5 μg) of ramosetron significantly improved abdominal pain/discomfort at second month (62.5%, P=.002), third month (60.6%, P=.005), and the last evaluation point (63.5%, P=.002) and weekly BSFS (P<.05) except at Week 8, 11, and 12 than placebo. IBS-QOL did not change. Ramosetron induced more constipation than placebo. CONCLUSIONS & INFERENCES The trial suggested that 2.5 μg of ramosetron is the most effective and least harmful option for treating female patients with IBS-D (Clinicaltrials.gov ID: NCT01274000).

Abstract
Gastroesophageal reflux disease-related diseases, such as Barrett's esophagus and adenocarcinoma of the esophagogastric junction (AEGJ), are believed to occur less frequently in Asia than in Western countries. However, the number of reported cases is increasing, yet little is known regarding the epidemiology of AEGJ in Japan. The primary study aim is to investigate the clinicoepidemiological characteristics of AEGJ. The secondary aim is to identify factors associated with it. In the 6.5 years between January 2008 and June 2014, we reviewed 88,199 esophagogastroduodenoscopy (EGD) reports and associated medical records (Study 1). We conducted a case-control study to identify factors associated with AEGJ (Study 2). Control subjects were randomly selected and age and sex matched from among subjects who underwent EGD during medical evaluations. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using an unconditional logistic regression method. During the study period, 83 patients with AEGJ (72 men and 11 women; mean age 68 years) were diagnosed. Six cases were Siewert type I and 77 were type II. The incidence rate of AEGJ was 0.6-1.7/100,000 person-years. Compared with the 101 control subjects, obesity (body mass index ≧ 25 kg/m2; [OR = 2.82; 95% CI: 1.13-7.01]) was associated with AEGJ. The incidence rate of AEGJ is lower in Japan than in Western countries, but associated factors similar to those in Western patients were detected, including obesity, a hiatal hernia, smoking, and the male sex.

Abstract
BACKGROUND/AIMS This prospective cohort study aimed to elucidate the incidence and characteristics of pneumonia associated with endoscopic submucosal dissection (ESD) of gastric neoplasms using CT. METHODS We included consecutive 188 patients with gastric neoplasms treated with ESD. All patients underwent CT before ESD and the day after ESD. Pneumonia associated with ESD was defined as lung ground glass opacity or consolidation by CT the day after ESD. RESULTS In 188 patients, 28 patients had diabetes mellitus. Pneumonia was observed by CT in 21 patients (11.2%) after ESD. Of those, 7 patients had diabetes mellitus. By univariate analysis, compared with patients with non-pneumonia complications, risk factors for pneumonia were significantly increased in patients with diabetes mellitus (p = 0.01) and in those who underwent a long procedure time (p = 0.02). By multivariate analysis, pneumonia was significantly increased in patients with diabetes mellitus (OR 4.06, 95% CI 1.35-12.19) and in those who underwent a long procedure time (OR 1.01, 95% CI 1.00-1.02). CONCLUSIONS The incidence of CT-diagnosed pneumonia associated with ESD was relatively high. Furthermore, it was revealed that diabetes mellitus and a long procedure time were risk factors of CT-diagnosed pneumonia.

Abstract
BACKGROUND Splenic vein ligation may result in sinistral (left-sided) portal hypertension and gastrointestinal haemorrhage. The aim of this study was to analyse the pathogenesis of sinistral portal hypertension following splenic vein ligation in pancreaticoduodenectomy. METHODS Patients who underwent pancreaticoduodenectomy for pancreatic cancer between January 2005 and December 2012 were included in this retrospective study. The venous flow pattern from the spleen and splenic hypertrophy were examined after surgery. RESULTS Of 103 patients who underwent pancreaticoduodenectomy with portal vein resection, 43 had splenic vein ligation. There were two predominant venous flow patterns from the spleen. In the varicose route (27 patients), flow from the spleen passed to colonic varices and/or other varicose veins. In the non-varicose route, flow from the spleen passed through a splenocolonic collateral (14 patients) or a spontaneous splenorenal shunt (2 patients). The varicose route was associated with significantly greater splenic hypertrophy than the non-varicose route (median splenic hypertrophy ratio 1·52 versus 0·94; P < 0·001). All patients with the varicose route had colonic varices, and none had a right colic marginal vein at the hepatic flexure. CONCLUSION Pancreaticoduodenectomy with splenic vein ligation may lead to sinistral portal hypertension. To avoid the development of varices, it is important to preserve the right colic marginal vein. Reconstruction of the splenic vein should be considered if the right colic marginal vein is divided.

Abstract
BACKGROUND This long-term 48-week study of acotiamide was carried out to investigate the efficacy, safety and administration pattern in patients with functional dyspepsia (FD). METHODS This was a multicenter, open-label, single-arm, long-term phase III study in which patients with FD were given acotiamide, 100 mg t.i.d., for 48 weeks. The two major efficacy endpoints were global overall treatment efficacy (OTE) and the elimination rate of three cardinal symptoms (i.e. postprandial fullness, early satiation and upper abdominal bloating), which were evaluated weekly and daily by the patients, respectively. The long-term administration patterns were investigated by following the patients based on cessation and readministration criteria. RESULTS Efficacy was analyzed in 405 patients. The OTE improvement rate was 26.1% at week 1 and increased with time. It was 60.6% at week 8 and subsequently maintained. Similarly, the symptom elimination rate increased up to week 8. Many patients who met the cessation criterion achieved remission of FD symptoms after experiencing dose interruption and readministration. The incidence rate of adverse drug reactions was 11.5% and most of the adverse drug reactions were mild in severity except increased ALT in 1 patient. CONCLUSION FD symptoms were controlled by intermittent administration of acotiamide even in patients with relapsing FD.

Abstract
BACKGROUND Acotiamide is a selective acetylcholinesterase inhibitor and enhances the actions of cholinergic neurons localized in the stomach. METHODS The present two studies were conducted to examine the optimal dosage of acotiamide hydrochloride (Z-338) in patients with functional dyspepsia (FD) in Japan. KEY RESULTS The improvement rate of 'subjects global assessment of overall treatment efficacy (OTE)' at the final evaluation was approximately 10% higher in the acotiamide 100 mg group than that in the placebo group with good reproducibility though there was no significant differences at primary endpoint. The elimination rate of postprandial fullness in the acotiamide 100 mg group was significantly higher compared to placebo group. In addition, the post hoc analysis showed that in patients whose main complaints are meal-related symptoms such as postprandial fullness, upper abdominal bloating and/or early satiety, the improvement rate of 'OTE' at final evaluation in acotiamide 100 mg group was significantly superior to that in the placebo group. CONCLUSIONS & INFERENCES These results suggest that acotiamide possesses efficacy on FD and more specifically its meal-related symptoms of FD.

Abstract
The purpose of the current study was to evaluate the incidence and course of upper-extremity deep vein thrombosis (UEDVT) related to an implanted central venous port (CV-port) system in cancer patients. From July 2007 to July 2008, 92 consecutive patients who underwent implantation of a CV-port for chemotherapy for colorectal cancer were prospectively enrolled in the study. All patients were examined at prescribed intervals by ultrasonography (US) to estimate the incidence of catheter-related venous thrombosis. We categorised ultrasound diagnosis into three types: Type 0, no thrombus; Type I, thrombi around catheter without obstruction of venous flow; Type II: thrombi with obstruction of venous flow. Upon initial ultrasound examination, 25 cases (27%) were categorised as Type 0, 64 (70%) as Type I and III (3%) as Type II. Of the 64 Type-I cases, 4 cases worsened to Type II within a month, and 3 others (including 1 patient who developed pulmonary embolism) became Type II after 1 month. Of the other Type-I cases, 12 cases improved to Type 0 and 45 cases remained Type I. All 10 patients categorised as Type II underwent anticoagulant therapy and resumed their chemotherapy without exacerbations of thrombosis. In cancer patients undergoing long-term chemotherapy, there is an unexpectedly high prevalence of catheter-related UEDVT, which can be detected by ultrasound at an early stage after implantation of a CV-port. Given that cancer patients with UEDVT may have worse outcomes than those without, clinicians should consider careful monitoring for UEDVT and introducing anticoagulant therapy.

Abstract
After the screening of microorganism culture, the culture of Propionibacterium freudenreichii ET-3 in the milk whey (milk whey culture) was found to stimulate the growth of our own Bifidobacteria in the colon but not the growth of other microorganisms. One of the active substances was identified as 1,4-dihydroxy-2-naphthoic acid (DHNA).In healthy volunteers, the ingestion containing milk whey culture significantly increased the population of Bifidobacteria to total fecal bacterium. In the TNBS-induced colitis model of rats, milk whey culture significantly accelerated the healing of the colitis in a dose-dependent manner. It has been reported that DHNA inhibited the lymphocyte infiltration through reduction of MAdCAM-1 in DSS colitis model of mice and that the ingestion of milk whey culture was effective in the treatment of ulcerative colitis in human pilot study. These findings suggest that milk whey culture is a useful prebiotic for the therapy of inflammatory bowel disease.
