RESUMO
BACKGROUND: The optimal duration of regimens for tailored therapy based on genotypic resistance for clarithromycin has yet to be established. AIM: This study was a nationwide, multicenter, randomized trial comparing empirical therapy with tailored therapy based on genotypic resistance for first-line eradication of Helicobacter pylori. We also compared the eradication rates of 7- and 14-day regimens for each group. PATIENTS AND METHODS: Patients with H. pylori infection were first randomized to receive empirical or tailored therapy. Patients in each group were further randomized into 7- or 14-day regimens. Empirical therapy consisted of a triple therapy (TT) regimen (twice-daily doses of pantoprazole 40 mg, amoxicillin 1 g, and clarithromycin 500 mg) for 7 or 14 days. Tailored therapy consisted of TT of 7 or 14 days in patients without genotypic resistance. Patients with genotypic resistance were treated with bismuth quadruple therapy (BQT) regimens (twice-daily doses of pantoprazole 40 mg, three daily doses of metronidazole 500 mg, and four times daily doses of bismuth 300 mg and tetracycline 500 mg) for 7 or 14 days. A 13C-urea breath test assessed eradication rates. The primary outcome was eradication rates of each group. RESULTS: A total of 593 patients were included in the study. The eradication rates were 65.7% (201/306) in the empirical therapy group and 81.9% (235/287) in the tailored therapy group for intention-to-treat analysis (p < 0.001). In the per-protocol analysis, the eradication rates of the empirical therapy and tailored groups were 70.3% (201/286) and 85.5% (235/274) (p < 0.001), respectively. There was no difference in compliance between the two groups. The rate of adverse events was higher in the tailored group compared to the empirical group (p < 0.001). DISCUSSION: Our study confirmed that tailored therapy based on genotypic resistance was more effective than empirical therapy for H. pylori eradication in Korea. However, no significant difference was found between 7- and 14-day regimens for each group. Future studies are needed to determine the optimal duration of therapy for empirical and tailored therapy regimens.

Although endoscopic forceps biopsy is the gold standard for early gastric cancer (EGC) diagnosis, the method can cause endoscopic resection of specimens and histological discrepancies. This study aims to examine the risk factors for histological discrepancies in EGC and long-term clinical outcomes. This retrospective study included patients diagnosed with differentiated-type EGC using forceps biopsy. Patients without histological discrepancies and with undifferentiated types in endoscopic resection histology were categorized into the concordant and discordant groups, respectively. Clinical characteristics and long-term outcomes related to histological discrepancies were analyzed. A total of 957 lesions from 936 patients were enrolled. An overall discrepancy rate of 8.7% was confirmed, with an undifferentiated-type discrepancy of 5.5%. The discordant group showed a higher tendency for lesions to be located in the upper third region, to have whitish discoloration, and to undergo a greater number of biopsies compared with the concordant group. Multivariate analysis confirmed that lesion location in the upper third region (odds ratio [OR]: 2.125; 95% confidence interval [CI]: 1.032-5.277; Pâ =â .041) and whitish surface discoloration (OR: 13.615; 95% CI: 6.028-28.728; Pâ =â .001) were significantly correlated with histologic discrepancy. Compared with the concordant group, the discordant group had a lower curative resection rate, but no differences were observed in complications, local recurrence, or survival rates. Upper third location and whitish discoloration were risk factors for the histologic discrepancy between differentiated and undifferentiated types in patients with EGC. For curative resections performed in patients with EGC and histologic discrepancies and without additional treatment, careful follow-up is possible.

INTRODUCTION: A narrow safety margin (NSM) after endoscopic submucosal dissection (ESD) is a well-recognized risk factor for local recurrence in early gastric cancer (EGC). However, only a few studies have investigated the risk factors for the development of NSM. METHODS: The medical records and pathologic specimens of patients with EGC who underwent ESD from January 2020 to December 2020 at a single tertiary hospital (Daejeon, South Korea) were reviewed. RESULTS: A total of 218 patients were enrolled and 29 had NSM (<3 mm). When comparing the NSM and the control groups, the size of the lesion, the depth of invasion, and the operating endoscopist were found to be risk factors for the development of NSM. The increased length of the subepithelial spread of the lesion was associated with a narrower safety margin. Logistic regression analysis revealed that lesion size was a risk factor for NSM, and a marginally significant difference between endoscopists was found. CONCLUSIONS: Multiple factors may need to be considered during ESD, including lesion size, invasion depth, operating endoscopist, and subepithelial spread.

Background/Aims: H2 receptor antagonists (H2RA) have been used to treat gastritis by inhibiting gastric acid. Proton pump inhibitors (PPIs) are more potent acid suppressants than H2RA. However, the efficacy and safety of low-dose PPI for treating gastritis remain unclear. The aim was to investigate the efficacy and safety of low-dose PPI for treating gastritis. Methods: A double-blind, noninferiority, multicenter, phase 3 clinical trial randomly assigned 476 patients with endoscopic erosive gastritis to a group using esomeprazole 10 mg (DW1903) daily and a group using famotidine 20 mg (DW1903R1) daily for 2 weeks. The full-analysis set included 319 patients (DW1903, n=159; DW1903R1, n=160) and the per-protocol set included 298 patients (DW1903, n=147; DW1903R1, n=151). The primary endpoint (erosion improvement rate) and secondary endpoint (erosion and edema cure rates, improvement rates of hemorrhage, erythema, and symptoms) were assessed after the treatment. Adverse events were compared. Results: According to the full-analysis set, the erosion improvement rates in the DW1903 and DW1903R1 groups were 59.8% and 58.8%, respectively. According to the per-protocol analysis, the erosion improvement rates in the DW1903 and DW1903R1 groups were 61.9% and 59.6%, respectively. Secondary endpoints were not significantly different between two groups except that the hemorrhagic improvement rate was higher in DW1903 with statistical tendency. The number of adverse events were not statistically different. Conclusions: DW1903 of a low-dose PPI was not inferior to DW1903R1 of H2RA. Thus, lowdose PPI can be a novel option for treating gastritis (ClinicalTrials.gov Identifier: NCT05163756).

BACKGROUND: Proton-pump inhibitors (PPIs) are the most effective drugs for treating acid-related disorders. However, once-daily dosing with conventional PPIs fail to fully control acid secretion over 24 h. This study aimed to compare the efficacy and safety of HIP1601 (dual delayed-release esomeprazole) and HGP1705 (delayed-release esomeprazole) in patients with erosive esophagitis (EE). METHODS: We enrolled 213 patients with EE randomized in a 1:1 ratio to receive 40 mg HIP1601 (n = 107) or HGP1705 (n = 106) once daily for 4 or 8 weeks. The primary endpoint was the EE healing rate, confirmed by endoscopy up to week 8. GERD-related symptoms and treatment-emergent adverse events were compared between both groups. RESULTS: By week 8, the estimated healing rates of EE were 97.8% and 96.8% in the HIP1601 and HGP1705 groups, respectively, with a 95% confidence interval of -4.7 to 7.2. After 4 or 8 weeks of treatment, the EE healing rate at week 4, complete resolution rate of symptoms, time to sustained resolution of symptoms, and number of rescue medications used were similar in both groups. The proportion of heartburn- and acid regurgitation-free nights by week 4 were higher in the HIP1601 group compared to the HGP1705 group, but the difference did not reach clinical significance (87.7% vs. 85.8%, P = 0.514, 87.5% vs. 85.8%, P = 0.774). The number of adverse events did not differ significantly between the two groups. CONCLUSIONS: The efficacy and safety of HIP1601 40 mg were comparable to those of HGP1705 40 mg for the treatment of EE and symptomatic improvement of GERD.

Post-infectious irritable bowel syndrome (PI-IBS) occurs in about 10% of cases following gastroenteritis. The incidence of IBS is higher in females. However, it is not clear whether this is due to biological or psychosocial factors. We aimed to investigate the influence of gender roles on the incidence of PI-IBS, alongside traditional risk factors. Our study included 231 patients diagnosed with gastroenteritis who were hospitalized and treated with antibiotics between 2018 and 2021. The Korean Sex Role Inventory-Short Form (KSRI-SF), based on the Bem Sex Role Inventory (BSRI) was used to categorize patients (androgynous, masculine, feminine, and undifferentiated types). Six months after treatment, we conducted a telephone survey to confirm the presence of PI-IBS using the ROME IV criteria. Among the patients, 43.3% were female, and the mean age was 43.67 ± 16.09 years. After 6 months, 34 patients developed PI-IBS. Univariate analysis revealed that younger age, female sex, KSRI-SF undifferentiated type, and longer duration of antibiotic use independently influenced the occurrence of PI-IBS. Multivariate analysis showed that PI-IBS was associated with the KSRI-SF undifferentiated type and higher C-reactive protein (CRP) levels. Our study showed that the KSRI-SF undifferentiated type and high CRP levels at initial infection were associated with PI-IBS.

Aberrant regulation of the long non-coding RNA SRY-box transcription factor 2 overlapping transcript (SOX2OT) has been reported in various diseases including gastric cancer (GC). However, an association between the well-studied rs9839776 single nucleotide polymorphism in SOX2OT and GC susceptibility has not been reported. This study aimed to evaluate the association between the rs9839776 single nucleotide polymorphism in SOX2OT and GC risk. Genotyping of rs9839776 was conducted using TaqMan genotyping assay for 460 patients with GC and 386 controls. We found that the dominant model (CT+TT) and rs9839776 T allele were significantly associated with decreased GC risk (Pâ =â .046, adjusted odds ratio [AOR]â =â 0.72, 95% confidence interval [CI]â =â 0.52-1.00 and Pâ =â .044, AORâ =â 0.74, 95% CIâ =â 0.56-0.99, respectively). In addition, stratified analysis revealed that the dominant model (CT+TT) and rs9839776 T allele were significantly associated with decreased risk of lymph node metastasis-negative (Pâ =â .039, AORâ =â 0.67, 95% CIâ =â 0.46-0.98 and Pâ =â .049, AORâ =â 0.71, 95% CIâ =â 0.51-1.00, respectively) and tumor stage I (A+B)/II (A+B+C) (Pâ =â .028, AORâ =â 0.66, 95% CIâ =â 0.50-0.96 and Pâ =â .041, AORâ =â 0.71, 95% CIâ =â 0.52-0.99, respectively) GC. Our findings suggest that the rs9839776 T allele may be a protective factor against GC susceptibility. Further research is needed to clarify whether rs9839776 affects SOX2OT expression.

Acute upper gastrointestinal bleeding (UGIB) is one of the most urgent medical conditions, with peptic ulcer bleeding (PUB) accounting for most gastrointestinal bleeding cases. The Japanese scoring system was developed to predict the probability of intervention in patients with UGIB, and it is more effective than other scoring systems, according to several studies. This study aimed to verify whether the Japanese scoring system is better than other scoring systems in predicting the probability of intervention when limited to PUB in patients with UGIB. We enrolled patients who presented with symptoms of UGIB and were diagnosed with peptic ulcers using endoscopy. The performances of the scoring systems in predicting patient outcomes were validated and compared using the receiver-operating characteristic curve analysis. Additionally, we used the chi-square test, Fisher exact test, and the t test to analyze the association between the patients characteristics and clinical outcomes. Of the 1228 patients diagnosed with peptic ulcers, 90.6% underwent endoscopy. rebleeding occurred in 12.5% of the patients, and 2.5% of the patients died within 30 days. The Japanese score was the most effective in predicting the need for endoscopic intervention for PUB. Sex, systolic blood pressure, hematemesis, syncope, blood urea nitrogen level, and the American Society of Anesthesiologists score were predictive factors for the probability of endoscopic intervention in patients with PUB. The Japanese score is an effective predictor of the probability of endoscopic intervention in patients with PUB.

Background/Aims: Papillary adenocarcinoma is classified to differentiated-type gastric cancer and is indicated for endoscopic submucosal dissection. However, due to its rare nature, there are limited studies on it. The purpose of this study was to determine the outcome of endoscopic submucosal dissection in patients with papillary-type early gastric cancer and to find the risk factors of lymph node metastasis. Methods: Patients diagnosed with papillary-type early gastric cancer at eight medical centers, who underwent endoscopic submucosal dissection or surgical treatment, were retrospectively reviewed. The clinical results and long-term outcomes of post-endoscopic submucosal dissection were evaluated, and the risk factors of lymph node metastasis in the surgery group were analyzed. Results: One-hundred and seventy-six patients with papillary-type early gastric cancer were enrolled: 44.9% (n=79) in the surgery group and 55.1% (n=97) in the endoscopic submucosal dissection group. As a result of endoscopic submucosal dissection, the en bloc resection and curative resection rates were 91.8% and 86.6%, respectively. The procedure-related complication rate was 4.1%, and local recurrence occurred in 3.1% of patients. Submucosal invasion (odds ratio, 3.735; 95% confidence interval, 1.026 to 12.177; p=0.047) and lymphovascular invasion (odds ratio, 7.636; 95% confidence interval, 1.730 to 22.857; p=0.004) were the risk factors of lymph node metastasis in papillary-type early gastric cancer patients. Conclusions: The clinical results of endoscopic submucosal dissection in papillary-type early gastric cancer were relatively favorable, and endoscopic submucosal dissection is considered safe if appropriate indications are confirmed by considering the risk of lymph node metastasis.
RESUMO
BACKGROUND: Few studies have compared the therapeutic outcomes in patients with HCC who underwent laparoscopic radiofrequency ablation (LRFA) versus percutaneous radiofrequency ablation (PRFA) for hepatocellular carcinoma (HCC). Therefore, this study compared the recurrence and survival outcomes of the two RFA methods in patients with HCC. METHODS: Recurrence and overall survival outcomes were evaluated in 307 patients who underwent LRFA (n = 151) or PRFA (n = 156) as a treatment method for de novo HCC. Inverse probability of treatment weighting (IPTW) analysis was performed to reduce the impact of treatment selection bias. RESULTS: There were no significant differences in major baseline characteristics between the LRFA and PRFA groups. However, the proportion of cirrhotic patients was higher in the LRFA group, whereas the LRFA group had more tumors and a more advanced tumor-node-metastasis stage. Moreover, the mean tumor size was significantly larger in the LRFA group than in the PRFA group. In a multivariate analysis, serum albumin level, more than three tumors, and the RFA method were identified as significant predictors of recurrence-free survival. Moreover, for the overall survival of HCC patients, serum albumin levels, days of hospital stay during RFA, and the RFA method were independent predictors. In the IPTW-adjusted analysis, the LRFA group showed significantly higher recurrence-free survival and overall survival. CONCLUSIONS: Our study revealed that compared with PRFA, LRFA was associated with longer recurrence-free survival and favorable overall survival in patients with HCC. Therefore, LRFA should be considered the primary therapy in patients with HCC eligible for RFA.

Extraintestinal manifestations (EIMs) are common in patients with inflammatory bowel disease (IBD); however, studies surrounding EIMs are lacking, particularly in Asia. This study aimed to identify risk factors by analyzing the characteristics of patients with EIMs. From January 2010 to December 2020, the medical records of 531 patients diagnosed with IBD (133 with Crohn disease [CD] and 398 with ulcerative colitis [UC]) were reviewed. The patients' baseline characteristics and risk factors were analyzed by dividing them into 2 groups according to EIMs presence. The prevalence of EIMs in all patients with IBD was 12.4% (nâ =â 66), of which CD and UC prevalences were 19.5% (nâ =â 26) and 10.1% (nâ =â 40), respectively. The articular (7.9%, nâ =â 42), cutaneous (3.6%, nâ =â 19), ocular (1.5%, nâ =â 8), and hepatobiliary types (0.8%, nâ =â 4) of EIMs were observed. Two or more EIMs occurred in only 1.2% of all IBD patients (nâ =â 6). Multivariate analysis revealed that the risk factors for the occurrence of EIMs were a follow-up periodâ ≥â 10 years (odds ratio, 2.106; 95% confidence interval, 1.187-3.973; Pâ =â .021) and treatment with biologics (odds ratio, 1.963; 95% confidence interval, 1.070-3.272; Pâ =â .037). The EIMs prevalence in patients with IBD was 12.4%, and the particular type was the most common, with EIMs occurring more frequently in patients with CD than in those with UC. Patients who have been treated for IBD for more than 10 years or who are using biologics should be carefully monitored as they are at high risk for EIMs.

PURPOSE: Lower gastrointestinal (GI) bleeding can be fatal; therefore, several scoring systems have been developed to predict its prognosis. We compared the mortality predictions and evaluated the usefulness of various scoring systems. METHODS: The medical records of 3794 patients who visited the emergency department with hematochezia between January 2016 and December 2021 were retrospectively reviewed. We calculated the areas under the receiver operating characteristic curves for 30-day mortality and prolonged hospital stay (≥ 10 days) based on the age, blood tests, and comorbidities (ABC); AIMS65; Glasgow-Blatchford; Oakland; Rockall (pre-endoscopy); and SHA2PE scores and compared the predictive accuracy of each score. RESULTS: Data for 963 patients (median age, 69 years; males, 54.5%; median hospital stay, 6 days) with colonoscopy-confirmed lower GI bleeding were analyzed. The 30-day mortality rate was 3.5%; the most common causes of lower GI bleeding were ischemic colitis and diverticulum bleeding in 19.3% and 19.2% of the cases, respectively. The AIMS65 and ABC scores were superior in predicting 30-day mortality (p < 0.001). The SHA2PE score was the most accurate predictor of prolonged hospital stay (p < 0.001). Through multivariate regression analysis, 30-day mortality was correlated with albumin level ≤ 3.0 g/dL, international normalized ratio > 1.5, blood urea nitrogen level ≥ 30 mg/dL, and systolic blood pressure (SBP) < 100 mmHg. A prolonged hospital stay was correlated with liver cirrhosis, hemoglobin ≤ 10 g/dL, albumin level ≤ 3.0 g/dL, and SBP < 100 mmHg. CONCLUSION: The recently developed scoring systems accurately predict lower GI bleeding prognosis, and their usefulness in clinical decision-making was confirmed.

BACKGROUND: Various scoring systems have been developed to predict endoscopic intervention, mortality, and rebleeding in patients with nonvariceal upper gastrointestinal bleeding (NVUGIB); however, they have not been sufficiently validated in Korea. Therefore, this study aimed to evaluate the usefulness of several scoring systems in Korea by validating and comparing the Japanese score and other scores in Korean people with NVUGIB. METHODS: The medical records of 1,368 patients with NVUGIB were reviewed to collect statistical, clinical, laboratory, and endoscopic data. The Japanese score, ABC score, Glasgow-Blatchford Bleeding Score (GBS), and MAP score were calculated retrospectively at a single research institution. These scores for predicting the need for endoscopic intervention, mortality, and rebleeding were calculated and evaluated using the area under the receiver operating characteristic curve. RESULTS: Of 1,368 patients, 88.5% required endoscopic intervention, 4.1% died within 30 days, and 12.6% experienced rebleeding. The Japanese score was effective for predicting endoscopic intervention, and the ABC score was best for predicting 30-day mortality. Sex, age, hematemesis, blood urea nitrogen, and American Society of Anesthesiologists score were found to be predictors of the need for endoscopic intervention. CONCLUSION: The Japanese score did not prove useful in Koreans with upper gastrointestinal bleeding. Additional research is needed due to the limitations of a retrospective study conducted in a single research institute.

Introduction: Although signet ring cell carcinoma (SRC) is a subtype of poorly cohesive carcinoma (PC), the differences in the biological behavior between the 2 morphologically similar carcinomas have not been fully studied. Therefore, we performed transcriptome analysis to evaluate the differences of genetic expressions between SRC and PC. Methods: The study group consisted of patients with SRC or PC pathology from patients with early gastric cancer (EGC) whose depth of invasion was localized in the mucosal layer. A total of 18 patients were enrolled. The patients were divided into 3 groups based on their histologic type and lymph node (LN) status. Group 1 consisted of patients with PC and positive LN metastasis, Group 2 consisted of patients with PC without LN metastasis, and Group 3 consisted of patients with SRC without LN metastasis. Transcriptome analysis was performed using the nCounter PanCancer Progression Panel Kit. Results: The expression of 77 genes in Group 1 was altered compared to that in normal tissues. The expression of 49 and 13 genes in Groups 2 and 3, respectively, was altered when compared to that in normal tissues. Groups 1 and 2 showed similar genetic expressions. However, Group 3 showed numerous differences in gene expression including Roundabout4 (Robo4) compared to the other groups, especially Group 1. Conclusion: Our data suggest that gene expression patterns were different between SRC and PC and expression of ROBO4 may play an important role in the prognosis of SRC and PC type of EGC.
RESUMO
BACKGROUND: Enteric fever is a systemic disease caused by Salmonella enterica serovar Typhi or Salmonella enterica serovar Paratyphi, characterized by high fever and abdominal pain. Most patients with enteric fever improve within a few days after antibiotic treatment. However, some patients do not recover as easily and develop fatal life-threatening complications, including intestinal hemorrhage. Lower gastrointestinal bleeding has been reported in 10% of cases. However, upper gastrointestinal bleeding has rarely been reported in patients with enteric fever. We present a case of gastric ulcer hemorrhage caused by enteric fever. CASE PRESENTATION: A 32-year-old woman, complaining of fever lasting four days and right upper quadrant pain and melena that started one day before admission, consulted our hospital. Abdominal computed tomography revealed mild hepatomegaly and gastroscopy revealed multiple active gastric ulcers with flat black hemorrhagic spots. The melena of the patient stopped on the third day. On the fifth admission day, she developed hematochezia. At that time, Salmonella enterica serovar Typhi was isolated from the blood culture. The antibiotic regimen was switched to ceftriaxone. Her hematochezia spontaneously resolved the following day. Finally, the patient was discharged on the 12th admission day without clinical symptoms. However, her fever recurred one month after discharge, and she was readmitted and Salmonella enterica serovar Typhi was confirmed again via blood culture. She was treated with ceftriaxone for one month, and was discharged without complications. CONCLUSION: Our case showed that although rare, active gastric ulcers can develop in patients with enteric fever. Therefore, upper and lower gastrointestinal bleeding should be suspected in patients with enteric fever, especially showing relapsing bacteremia.

BACKGROUND/AIMS: Several conditions may cause difficulties with oral feeding. Percutaneous endoscopic gastrostomy (PEG) is commonly performed on patients who require enteral feeding for >2-3 weeks. This study examined the nutritional state of patients who required enteral feeding and underwent PEG to quantify the benefits of the procedure. METHODS: This retrospective study included patients who underwent PEG at the Chungnam National University Hospital between January 2013 and December 2018. A gastroenterologist performed all PEG procedures using the pull technique, and all patients were followed up for >3 weeks postoperatively. The BMI and lymphocyte count, along with the levels of hemoglobin, total protein, albumin, total cholesterol, BUN, and creatinine pre-PEG and between 3 weeks and 6 months post-PEG were evaluated. RESULTS: Overall, 151 patients (116 males; mean age 64.92 years) were evaluated. Of these patients, 112 (74.2%), 34 (22.5%), and five (3.3%) underwent PEG tube insertion because of neurological diseases, malignancy, and other conditions, respectively. The BMI and the hemoglobin, total protein, albumin, and total cholesterol levels were significantly higher post-PEG than pre-PEG. CONCLUSIONS: These findings highlight the usefulness of PEG in the management of nutritionally poor patients with difficulties in feeding orally.

BACKGROUND: Colonoscopy surveillance guidelines set the surveillance schedule based on polyp characteristics. Polyps with high-grade dysplasia (HGD) require 3 years of follow-up regardless of size. However, it is unclear whether patients with diminutive polyps (≤5 mm) with HGD have a higher risk. We evaluated the effect of diminutive adenoma with HGD on adenoma occurrence. METHODS: From January 2015 to December 2017, patients who underwent index and surveillance colonoscopy were retrospectively screened. The patients were grouped into no adenoma group, low-risk (patients with ≤2 low-grade dysplasia [LGD]), diminutive HGD, and high-risk (HGD >5 mm, ≥3 adenomas) groups according to the index colonoscopy results. Each group was analyzed using logistic analysis. RESULTS: The mean follow-up period was 22.47 months. Altogether, 610 (50.45%) patients had LGD and 152 (12.5%) had HGD. Among them, 61 (5.0%) patients had a diminutive polyp with HGD. Analysis of the risks of developing advanced adenoma in the surveillance colonoscopy showed that compared to the no adenoma group, the diminutive HGD group did not show a significant risk (odds ratio [OR] = 1.503 [0.449-5.027], p = 0.509), while the high-risk group showed a significant risk (OR = 2.044 [1.015-4.114], p = 0.045). CONCLUSIONS: Diminutive adenoma with HGD increased the risk of adenoma on surveillance colonoscopy, and in the case of advanced adenoma, the risk was increased, but it was not statistically significant.

BACKGROUND: Risk stratification is recommended for patients with gastrointestinal (GI) bleeding. The ABC score is a new scoring tool with high accuracy for upper and lower GI bleeding. We aimed to evaluate the effectiveness of the ABC score in predicting the outcomes of patients with peptic ulcer bleeding. METHODS: This single-center retrospective study included 809 patients, each with symptoms of upper GI bleeding, and who were diagnosed with ulcerative lesions between October 2011 and March 2021. The association between the ABC score's variables and the patients' outcome was analyzed. The score's performance in predicting the patients' outcome was validated using receiver-operating characteristic curve analysis and compared with that of other scores. RESULTS: The study analyzed 772 patients with peptic ulcer bleeding. The primary outcome measure was all-cause 30-day mortality. Secondary outcome measures included rebleeding within 30 days and the need for radiologic/surgical intervention. Age (Pâ =â .013), serum albumin levels (Pâ <â .001), serum creatinine levels (Pâ =â .004), mental status (Pâ <â .001), and American Society of Anesthesiologists score (Pâ <â .001) were associated with the primary outcome. The ABC score predicted the 30-day mortality (area under the receiver-operating characteristic curve [AUROC] 0.927; 95% confidence interval [CI] 0.899-0.956) better than other scores. However, it was less accurate in predicting rebleeding (AUROC 0.630; 95% CI 0.563-0.697) and need for radiologic/surgical intervention (AUROC 0.641; 95% CI 0.550-0.732). CONCLUSIONS: The ABC score accurately predicts the 30-day mortality in patients with peptic ulcer bleeding. However, it may not be suitable for predicting rebleeding or the need for radiologic/surgical interventions.

BACKGROUND: Lower gastrointestinal bleeding (LGIB) often subsides without medical intervention; however, in some cases, the bleeding does not stop and the patient's condition worsens. Therefore, predicting severe LGIB in advance can aid treatment. This study aimed to evaluate variables related to mortality from LGIB and propose a scoring system. METHODS: In this retrospective study, we reviewed the medical records of patients who visited the emergency room with hematochezia between January 2016 and December 2020. Through regression analysis of comorbidities, medications, vital signs, laboratory investigations, and duration of hospital stay, variables related to LGIB-related mortality were evaluated. A scoring system was developed and the appropriateness with an area under the receiver operating characteristics curve (AUROC) was evaluated and compared with other existing models. RESULTS: A total of 932 patients were hospitalized for LGIB. Variables associated with LGIB-related mortality were the presence of cancer, heart rate > 100 beats/min, blood urea nitrogen level ≥ 30 mg/dL, an international normalized ratio > 1.50, and albumin level ≤ 3.0 g/dL. The AUROCs of the models CNUH-4 and CNUH-5 were 0.890 (p < 0.001; cutoff, 2.5; 95% confidence interval, 0.0851-0.929) and 0.901 (p < 0.001; cutoff, 3.5; 95% confidence interval, 0.869-0.933), respectively. CONCLUSIONS: The model developed for predicting the risk of LGIB-related mortality is simple and easy to apply clinically. The AUROC of the model was better than that of the existing models.
