Abstract
PURPOSE Peptic ulcer is a multifactorial and complex disease and affects a wide range of people worldwide. We provided a novel therapeutic approach for peptic ulcer and observed its effect. METHODS Peptic ulcer patients were enrolled from 2016 to 2017 in Chongqing and randomly assigned to two groups: a control group that used only rabeprazole and a platelet-rich plasma (PRP) group that received a combination therapy of autologous PRP (aPRP) and rabeprazole. The therapeutic effect was assessed via the ulcer size and symptom score. RESULTS A total of 27 patients were included (12 patients in the control group and 15 patients in the PRP group) in this study. Our results showed that all participants have healed in 30 days, and there was no significant difference in healing time between the PRP group and the control group in different independent variables. However, regression analysis revealed that the healing time was 6.99 days shorter in the PRP group than that in the control group, and patients with higher symptom scores in the initial examination need more time to heal during treatment. Endoscopic results showed that the repaired ulcer in the PRP group was more similar to the normal gastric mucosa tissue than that the control group. CONCLUSION This study showed an encouraging preliminary result that aPRP has a positive result in patients with peptic ulcer and seems to be a better choice for refractory peptic ulcer treatment. Although further follow-up studies are needed to determine the duration of efficacy of aPRP, the approach will be helpful in improving the clinical treatment of peptic ulcer.

Evidence-based complementary and alternative medicine : eCAM. 2022;2022:6329592
Abstract
OBJECTIVE To analyze the efficacy and safety of somatostatin combined with gastroscopic administration of omeprazole in the treatment of acute upper gastrointestinal bleeding. METHODS Eligible 112 patients with acute upper gastrointestinal bleeding treated in our hospital from May 2019 to July 2020 were randomized at a ratio of 1 : 1 either to the control group (somatostatin) or observation group (somatostatin combined with omeprazole gastroscope administration). The treatment efficacy, the average hemostasis time, rebleeding rate, average length of hospital stay, and the incidence of adverse reactions were compared. RESULTS The study group demonstrated significantly higher total effective rate than the control group (96.45% vs. 80.36%, <0.05). The study group demonstrated superior performances compared to the control group with respect to the average hemostasis time ((14.17 ± 2.53 h) vs. (28.84 ± 4.07 h)), rebleeding rate (3.57% vs. 14.28%), and average length of hospital stay ((5.86 ± 1.26 d) vs. (9.74 ± 1.07 d)) (all p < 0.05). The chi-square test revealed a remarkably lower total incidence of adverse reactions in the study group vs. control group which was (4 (7.14%) vs. 12 (21.43%)) (p < 0.05). CONCLUSION The combination of somatostatin and gastroscopic administration of omeprazole might be a promising alternative for the treatment of acute upper gastrointestinal bleeding. It improves the clinical treatment effect and controls the symptoms of patients, with a good safety profile.

Abstract
BACKGROUND The apheresis technique is increasingly used in patients with hypertriglyceridemia-induced pancreatitis (HTGP), while its role in this context is still not well established. Thus, we aimed to evaluate the clinical outcomes of an apheresis therapy compared to usual care in such a patient population. METHODS We searched PubMed, Embase, and Cochrane library databases up to July 10, 2021. Studies were included if they focused on HTGP treated with or without apheresis technique. We used the Newcastle-Ottawa Scale to assess the quality of the included studies. The primary outcome was the mortality rate. We also explored the heterogeneity, sensitivity analysis, subgroup analysis, and publication bias. RESULTS Sixteen observational studies with 1476 adults were included. The overall quality of included studies was moderate. Despite better TG level reduction with apheresis therapy (mean difference [MD], 12.27 mmol/L, 95% CI, 3.74 to 20.81; I(2) = 78%; P = 0.005), use of apheresis did not reduce the mortality (odds ratio [OR], 1.01; 95% CI, 0.65 to 1.59; P = 0.95) compared with usual care. This result was further confirmed by sensitivity analysis, subgroup analysis. The length of stay in hospital (MD, 0.96 days; 95% CI, - 1.22 to 3.14; I(2) = 70%; P = 0.39) and most complications were similar between the groups, while hospital cost was significantly higher in the apheresis group. CONCLUSIONS The apheresis technique did not decrease the mortality in HTGP patients compared with usual care. Until the results of high-quality RCTs are known, these findings do not support the routine use of the apheresis technique in such a patient population.

Computer-Aided Diagnosis of Gastrointestinal Ulcer and Hemorrhage Using Wireless Capsule Endoscopy: Systematic Review and Diagnostic Test Accuracy Meta-analysis
Bang CS, Lee JJ, Baik GH
Journal of medical Internet research. 2021;23(12):e33267
Abstract
BACKGROUND Interpretation of capsule endoscopy images or movies is operator-dependent and time-consuming. As a result, computer-aided diagnosis (CAD) has been applied to enhance the efficacy and accuracy of the review process. Two previous meta-analyses reported the diagnostic performance of CAD models for gastrointestinal ulcers or hemorrhage in capsule endoscopy. However, insufficient systematic reviews have been conducted, which cannot determine the real diagnostic validity of CAD models. OBJECTIVE To evaluate the diagnostic test accuracy of CAD models for gastrointestinal ulcers or hemorrhage using wireless capsule endoscopic images. METHODS We conducted core databases searching for studies based on CAD models for the diagnosis of ulcers or hemorrhage using capsule endoscopy and presenting data on diagnostic performance. Systematic review and diagnostic test accuracy meta-analysis were performed. RESULTS Overall, 39 studies were included. The pooled area under the curve, sensitivity, specificity, and diagnostic odds ratio of CAD models for the diagnosis of ulcers (or erosions) were .97 (95% confidence interval, .95-.98), .93 (.89-.95), .92 (.89-.94), and 138 (79-243), respectively. The pooled area under the curve, sensitivity, specificity, and diagnostic odds ratio of CAD models for the diagnosis of hemorrhage (or angioectasia) were .99 (.98-.99), .96 (.94-0.97), .97 (.95-.99), and 888 (343-2303), respectively. Subgroup analyses showed robust results. Meta-regression showed that published year, number of training images, and target disease (ulcers vs erosions, hemorrhage vs angioectasia) was found to be the source of heterogeneity. No publication bias was detected. CONCLUSIONS CAD models showed high performance for the optical diagnosis of gastrointestinal ulcer and hemorrhage in wireless capsule endoscopy.

Abstract
BACKGROUND Inflammatory bowel disease affects approximately seven million people globally. Iron deficiency anaemia can occur as a common systemic manifestation, with a prevalence of up to 90%, which can significantly affect quality of life, both during periods of active disease or in remission. It is important that iron deficiency anaemia is treated effectively and not be assumed to be a normal finding of inflammatory bowel disease. The various routes of iron administration, doses and preparations present varying advantages and disadvantages, and a significant proportion of people experience adverse effects with current therapies. Currently, no consensus has been reached amongst physicians as to which treatment path is most beneficial. OBJECTIVES The primary objective was to evaluate the efficacy and safety of the interventions for the treatment of iron deficiency anaemia in people with inflammatory bowel disease. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, and two other databases on 21st November 2019. We also contacted experts in the field and searched references of trials for any additional trials. SELECTION CRITERIA Randomised controlled trials investigating the effectiveness and safety of iron administration interventions compared to other iron administration interventions or placebo in the treatment of iron deficiency anaemia in inflammatory bowel disease. We considered both adults and children, with studies reporting outcomes of clinical, endoscopic, histologic or surgical remission as defined by study authors. DATA COLLECTION AND ANALYSIS Two review authors independently conducted data extraction and 'Risk of bias' assessment of included studies. We expressed dichotomous and continuous outcomes as risk ratios and mean differences with 95% confidence intervals. We assessed the certainty of the evidence using the GRADE methodology. MAIN RESULTS We included 11 studies (1670 randomised participants) that met the inclusion criteria. The studies compared intravenous iron sucrose vs oral iron sulphate (2 studies); oral iron sulphate vs oral iron hydroxide polymaltose complex (1 study); oral iron fumarate vs intravenous iron sucrose (1 study); intravenous ferric carboxymaltose vs intravenous iron sucrose (1 study); erythropoietin injection + intravenous iron sucrose vs intravenous iron sucrose + injection placebo (1 study); oral ferric maltol vs oral placebo (1 study); oral ferric maltol vs intravenous ferric carboxymaltose (1 study); intravenous ferric carboxymaltose vs oral iron sulphate (1 study); intravenous iron isomaltoside vs oral iron sulphate (1 study); erythropoietin injection vs oral placebo (1 study). All studies compared participants with CD and UC together, as well as considering a range of disease activity states. The primary outcome of number of responders, when defined, was stated to be an increase in haemoglobin of 20 g/L in all but two studies in which an increase in 10g/L was used. In one study comparing intravenous ferric carboxymaltose and intravenous iron sucrose, moderate-certainty evidence was found that intravenous ferric carboxymaltose was probably superior to intravenous iron sucrose, although there were responders in both groups (150/244 versus 118/239, RR 1.25, 95% CI 1.06 to 1.46, number needed to treat for an additional beneficial outcome (NNTB) = 9). In one study comparing oral ferric maltol to placebo, there was low-certainty evidence of superiority of the iron (36/64 versus 0/64, RR 73.00, 95% CI 4.58 to 1164.36). There were no other direct comparisons that found any difference in the primary outcomes, although certainty was low and very low for all outcomes, due to imprecision from sparse data and risk of bias varying between moderate and high risk. The reporting of secondary outcomes was inconsistent. The most common was the occurrence of serious adverse events or those requiring withdrawal of therapy. In no comparisons was there a difference seen between any of the intervention agents being studied, although the certainty was very low for all comparisons made, due to risk of bias and significant imprecision due to the low numbers of events. Time to remission, histological and biochemical outcomes were sparsely reported in the studies. None of the other secondary outcomes were reported in any of the studies. An analysis of all intravenous iron preparations to all oral iron preparations showed that intravenous administration may lead to more responders (368/554 versus 205/373, RR 1.17, 95% CI 1.05 to 1.31, NNTB = 11, low-certainty due to risk of bias and inconsistency). Withdrawals due to adverse events may be greater in oral iron preparations vs intravenous (15/554 versus 31/373, RR 0.39, 95% CI 0.20 to 0.74, low-certainty due to risk of bias, inconsistency and imprecision). AUTHORS' CONCLUSIONS Intravenous ferric carboxymaltose probably leads to more people having resolution of IDA (iron deficiency anaemia) than intravenous iron sucrose. Oral ferric maltol may lead to more people having resolution of IDA than placebo. We are unable to draw conclusions on which of the other treatments is most effective in IDA with IBD (inflammatory bowel disease) due to low numbers of studies in each comparison area and clinical heterogeneity within the studies. Therefore, there are no other conclusions regarding the treatments that can be made and certainty of all findings are low or very low. Overall, intravenous iron delivery probably leads to greater response in patients compared with oral iron, with a NNTB (number needed to treat) of 11. Whilst no serious adverse events were specifically elicited with any of the treatments studied, the numbers of reported events were low and the certainty of these findings very low for all comparisons, so no conclusions can be drawn. There may be more withdrawals due to such events when oral is compared with intravenous iron delivery. Other outcomes were poorly reported and once again no conclusions can be made as to the impact of IDA on any of these outcomes. Given the widespread use of many of these treatments in practice and the only guideline that exists recommending the use of intravenous iron in favour of oral iron, research to investigate this key issue is clearly needed. Considering the current ongoing trials identified in this review, these are more focussed on the impact in specific patient groups (young people) or on other symptoms (such as fatigue). Therefore, there is a need for studies to be performed to fill this evidence gap.

Abstract
BACKGROUND The effectiveness of the hemostatic powder TC-325 as a single endoscopic treatment for acute nonvariceal upper gastrointestinal bleeding is uncertain. OBJECTIVE To compare TC-325 with standard endoscopic hemostatic treatments in the control of active bleeding from nonvariceal upper gastrointestinal causes. DESIGN One-sided, noninferiority, randomized, controlled trial. (ClinicalTrials.gov: NCT02534571). SETTING University teaching hospitals in the Asia-Pacific region. PATIENTS 224 adult patients with acute bleeding from a nonvariceal cause on upper gastrointestinal endoscopy. INTERVENTION TC-325 (n = 111) or standard hemostatic treatment (n = 113). MEASUREMENTS The primary outcome was control of bleeding within 30 days. Other outcomes included failure to control bleeding during index endoscopy, recurrent bleeding after initial hemostasis, further interventions, blood transfusion, hospitalization, and death. RESULTS 224 patients were enrolled (136 with gastroduodenal ulcers [60.7%], 33 with tumors [14.7%], and 55 with other causes of bleeding [24.6%]). Bleeding was controlled within 30 days in 100 of 111 patients (90.1%) in the TC-325 group and 92 of 113 (81.4%) in the standard treatment group (risk difference, 8.7 percentage points [1-sided 95% CI, 0.95 percentage point]). There were fewer failures of hemostasis during index endoscopy with TC-325 (3 [2.7%] vs. 11 [9.7%]; odds ratio, 0.26 [CI, 0.07 to 0.95]). Recurrent bleeding within 30 days did not differ between groups (9 [8.1%] vs. 10 [8.8%]). The need for further interventions also did not differ between groups (further endoscopic treatment: 8 [7.2%] vs. 10 [8.8%]; angiography: 2 [1.8%] vs. 4 [3.5%]; surgery: 1 [0.9%] vs. 0). There were 14 deaths in each group (12.6% vs. 12.4%). LIMITATION Clinicians were not blinded to treatment. CONCLUSION TC-325 is not inferior to standard treatment in the endoscopic control of bleeding from nonvariceal upper gastrointestinal causes.

BMJ open. 2021;11(5):e042374
Abstract
OBJECTIVE The goal of treatment in ulcerative colitis (UC) is to induce and maintain remission. The addition of granulocyte and monocyte apheresis (GMA) to conventional therapy may be a promising therapeutic alternative. In this meta-analysis, we aimed to assess the efficacy and safety profile of GMA as an adjunctive therapy. DESIGN Systematic review and meta-analysis. METHODS We searched four databases (MEDLINE, Embase, Web of Science and Cochrane Central Register of Controlled Trials) for randomised or minimised controlled trials which discussed the impact of additional GMA therapy on clinical remission induction and clinical remission maintenance compared with conventional therapy alone. Primary outcomes were clinical remission induction and maintenance, secondary outcomes were adverse events (AEs) and steroid-sparing effect. ORs with 95% CIs were calculated. Trial Sequential Analyses were performed to adjusts for the risk of random errors in meta-analyses. RESULTS A total of 11 studies were eligible for meta-analysis. GMA was clearly demonstrated to induce and maintain clinical remission more effectively than conventional therapy alone (598 patients: OR: 1.93, 95% CI 1.28 to 2.91, p=0.002, I(2)=0.0% for induction; 71 patients: OR: 8.34, 95% CI 2.64 to 26.32, p<0.001, I(2)=0.0% for maintenance). There was no statistically significant difference in the number of AEs (OR: 0.27, 95% CI 0.05 to 1.50, p=0.135, I(2)=84.2%). CONCLUSION GMA appears to be more effective as an adjunctive treatment in inducing and maintaining remission in patients with UC than conventional therapy alone.

Incidence of gastrointestinal bleeding after transesophageal echocardiography in patients with gastroesophageal varices: A systematic review and meta-analysis
Hui RW, Leung CM
Journal of the American Society of Echocardiography : official publication of the American Society of Echocardiography. 2021
Abstract
BACKGROUND Transesophageal echocardiography (TEE) is useful for cardiac assessment and intraoperative monitoring. However, the safety of TEE in cirrhotic patients with gastroesophageal varices has remained uncertain. This meta-analysis aims to determine the incidence of gastrointestinal bleeding after TEE in patients with varices. The secondary objectives are to compare the bleeding risks between patients with and without varices; and to determine the incidences of TEE-related esophageal perforation and mortality. METHODS Systematic literature search was conducted on MEDLINE, EMBASE and Cochrane Database using the terms "Transesophageal echocardiography", "Varices", "Bleeding", and related terms. Articles describing the incidence of post-TEE bleeding in patients with varices were included. Non-English articles were excluded. Risk of bias and level of evidence were assessed through validated scales. Pooled weighted incidence of gastrointestinal bleeding and risk difference in bleeding were calculated with a random effects model. RESULTS 569 articles were identified initially, and 10 articles (comprising of 908 patients) were included. The incidence of post-TEE bleeding in patients with varices was 0.84% (95% CI 0.34%-1.56%). When stratified by TEE indication, the pooled incidence of bleeding was 0.68% (95% CI 0.11%-1.63%) in intraoperative TEE; and 1.03% (95% CI 0.23%-2.29%) in diagnostic TEE. No cases of esophageal perforation or mortality were reported. Six studies included a comparator group of patients without varices, and the bleeding risk was comparable between patients with and without varices (risk difference 0.26%; 95% CI -0.80%-1.32%; I2=0%, p=0.88). Eight studies had moderate or high risk of bias, and overall level of evidence was low. CONCLUSION TEE appears to be associated with low gastrointestinal bleeding incidence in patients with gastroesophageal varices. Nonetheless, results should be treated with caution due to bias and low level of evidence. Large-scale high-quality studies will be required to confirm the safety of TEE in patients with gastroesophageal varices.

Endoscopy international open. 2021;9(8):E1283-e1290
Abstract
Background and study aims There is limited evidence on the effectiveness of hemostatic powders in the management of lower gastrointestinal bleeding (LGIB). We aimed to provide a pooled estimate of their effectiveness and safety based on the current literature. Patients and methods Literature review was based on computerized bibliographic search of the main databases through to December 2020. Immediate hemostasis, rebleeding rate, adverse events, and mortality were the outcomes of the analysis. Pooled effects were calculated using a random-effects model. Results A total of 9 studies with 194 patients were included in the meta-analysis. Immediate hemostasis was achieved in 95 % of patients (95 % confidence interval [CI] 91.6 %-98.5 %), with no difference based on treatment strategy or bleeding etiology. Pooled 7- and 30-day rebleeding rates were 10.9 % (95 %CI 4.2 %-17.6 %) and 14.3 % (95 %CI 7.3 %-21.2 %), respectively. Need for embolization and surgery were 1.7 % (95 %CI 0 %-3.5 %) and 2.4 % (95 %CI 0.3 %-4.6 %), respectively. Overall, two patients (1.9 %, 95 %CI 0 %-3.8 %) experienced mild abdominal pain after powder application, and three bleeding-related deaths (2.3 %, 95 %CI 0.2 %-4.3 %) were registered in the included studies. Conclusion Novel hemostatic powders represent a user-friendly and effective tool in the management of lower gastrointestinal bleeding.

Wang Y, Wang Y, Han J
American journal of translational research. 2021;13(5):5336-5342
Abstract
OBJECTIVE To explore the effect of refined nursing combined with targeted nursing on patients with gastrointestinal bleeding complicated by liver cirrhosis. METHODS 128 patients with gastrointestinal bleeding and liver cirrhosis admitted to our hospital from April 2018 to April 2019 were recruited as the study cohort and were randomly divided into a control group and an experimental group with 64 patients in each group. The patients in the control group underwent conventional nursing, and the experimental group underwent refined nursing combined with targeted nursing. The two groups' clinical efficacy, complication rates, psychological states, prognoses, quality of life, and nursing satisfaction were statistically analyzed. RESULTS The clinical curative effect, prognosis complication rate, psychological state scores, quality of life scores, and nursing satisfaction in the experimental group were significantly better than they were in the control group (P<0.05). CONCLUSION Refined nursing combined with targeted nursing has a more significant clinical effect than the conventional nursing mode due to its strengths in improving patients' prognoses, psychological states, and quality of life, and reducing the incidence of complications, improving the patients' nursing satisfaction, and establishing good doctor-patient relationships.
