BMC Gastroenterol 2023; 23:287. [PMID: 37605137 PMCID: PMC10440920 DOI: 10.1186/s12876-023-02923-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Accepted: 08/10/2023] [Indexed: 08/23/2023] Open
Abstract
BACKGROUND Helicobacter pylori (H. pylori) is one of the leading causes of peptic ulcers, and its treatment is a worldwide challenge. Matrix metalloproteinases and their inhibitors influence the development and healing of peptic ulcers. This study aimed to evaluate the ratios of matrix metalloproteinase-2 (MMP-2) to tissue inhibitor of metalloproteinase-1 (TIMP-1) in patients with peptic ulcers that are sensitive or resistant to H. pylori treatment and compare them with healthy individuals. METHODS In this study, 95 patients were included and divided into two groups sensitive (41 patients) and resistant to treatment (54 patients). The results were compared with a control group of 20 participants with normal endoscopy and H. pylori-negative. After obtaining written informed consent, five ml of venous blood was taken to determine their serum MMP-2 and TIMP-1 levels using an enzyme-linked immunosorbent assay. RESULTS In patients with H. pylori-induced peptic ulcers, the MMP-2/TIMP-1 ratio was significantly higher than the healthy controls (P < 0.05). MMP-2 level was associated with patients' response to treatment (P < 0.05). The MMP-2/TIMP-1 ratio was higher in patients with simultaneous gastric and duodenal ulcers (P < 0.05). CONCLUSION It seems that peptic ulcer disease caused by infection with H. pylori increases the MMP-2/TIMP-1 ratio in patients with peptic ulcers. However, it might not be a good predictor of refractory H. pylori-induced peptic ulcer disease.

Abstract
BACKGROUND AND AIM There is regional variation in the eradication rates of Helicobacter pylori (H. pylori) regimens depending on the local antibiotic resistance patterns. The aim of this study was to compare the efficacies of triple, quadruple and sequential antibiotic therapy in eradicating H. pylori infection. METHODS A total of 296 H. pylori-positive patients were randomized to receive one of the three regimens (triple, quadruple or sequential antibiotic therapy) and eradication rate was assessed by H. pylori stool antigen test. RESULTS The eradication rates of standard triple therapy, sequential therapy and quadruple therapy were 93%, 92.9% and 96.4%, respectively (p = 0.57). CONCLUSION Fourteen days of standard triple therapy, 14 days of bismuth-based quadruple therapy and 10 days of sequential therapy are equally efficacious in eradicating H. pylori and all regimens have optimum H. pylori eradication rates.

Abstract
A considerable portion of the world's population practices fasting, for religious purposes like Ramadan or to adopt a healthier lifestyle such as intermittent fasting. During this period, individuals undergo metabolic changes that alter their internal environment. The literature was analysed to identify a possible relationship between fasting and the development of Helicobacter pylori-induced peptic ulcers. This found that fasting does not affect the incidence of peptic ulcers, and studies that saw an increase in the incidence were not significant. However, remodelling of the gastric environment and increases in concentrations of H. pylori were recorded. There is no relationship between fasting and the risk of developing H. pylori-induced peptic ulcers, suggesting that individuals with uncomplicated ulcers are not at risk of developing further ulcers and can participate in fasts provided they take the recommended measures.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Campomanesia lineatifolia Ruiz & Pavón (Myrtaceae), an edible species found in Brazilian Forest, possesses leaves that are traditionally used for the treatment of gastrointestinal disorders in Brazil. Extracts of C. lineatifolia are rich in phenolics and exhibit antioxidant, and gastric antiulcer properties. Furthermore, Campomanesia spp. have been described to possess anti-inflammatory properties, but studies related to chemical constituents of C. lineatifolia are scarce in the literature. AIM OF THE STUDY This work aims to identify the chemical composition of the phenolic-rich ethanol extract (PEE) from C. lineatifolia leaves and evaluate the anti-inflammatory activity that could be related to its ethnopharmacological use. MATERIALS AND METHODS The high-speed countercurrent chromatography (HSCCC), using an isocratic and a step gradient elution method, and NMR, HPLC-ESI-QTOF-MS/MS were used to isolate and identify the chemicals of PEE, respectively. Lipopolysaccharide-(LPS)-stimulated THP-1 cells were used to evaluate the anti-inflammatory activities from PEE and the two majority flavonoids isolated by measure TNF-α and NF-κB inhibition assays. RESULTS Fourteen compounds were isolated from the PEE, further identified by NMR and HPLC-ESI-QTOF-MS/MS, twelve of them are new compounds, and two others are already known for the species. The PEE, quercitrin and myricitrin promoted a concentration-dependent inhibition of TNF-α, and PEE promoted an inhibition of NF-κB pathway. CONCLUSIONS PEE from C. lineatifolia leaves demonstrated significant anti-inflammatory activity that may be related to the traditional use to treat gastrointestinal disorders.

Figueiredo FDF, Damazo AS, Arunachalam K, Silva MJD, Pavan E, Lima JCDS, Martins DTDO. Evaluation of the gastroprotective and ulcer healing properties by Fridericia chica (Bonpl.) L.G. Lohmann hydroethanolic extract of leaves. JOURNAL OF ETHNOPHARMACOLOGY 2023; 309:116338. [PMID: 36870462 DOI: 10.1016/j.jep.2023.116338] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 02/23/2023] [Accepted: 02/24/2023] [Indexed: 06/18/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Fridericia chica (Bonpl.) L.G. Lohmann (Bignoniaceae), is a climber native to Brazil, found in all Brazilian biomes. It is mostly known in Brazil as "carajiru," and home medicines made from the leaves have been used to cure disorders including stomach ulcers and other gastrointestinal disorders. AIM OF THE STUDY The objective of the study was to investigate the F. chica hydroethanolic extract of leaves (HEFc) preventative and curative antiulcer gastrointestinal efficacy as well as the mechanisms of action using in vivo rodent models. MATERIALS AND METHODS F. chica was collected in the municipality of Juína, Mato Grosso, and its leaves were used to prepare the extract by maceration technique (70% hydroethanol in the 1:10 ratio, w/v) to obtain the HEFc. The chromatographic analysis of HEFc was carried out by High Performance Liquid Chromatography-Photo Diode Array-Electrospray Ionization-Mass Spectrometry (HPLC-PDA-ESI-MS)- LCQ Fleet™ system. To determine the potential antiulcer potential of HEFc (1, 5 and 20 mg/kg, p.o.), the gastroprotective activity was assessed in various animal models of stomach ulcers caused by acidified ethanol, water constraint stress, indomethacin, (acute), and acid acetic (chronic). Additionally, the prokinetic properties of the HEFC were assessed in mice. The gastroprotective underlying mechanisms were evaluated by the histopathological analysis and determination of gastric secretion (volume, free and total acidity), gastric barrier mucus, activation of PGs, NO, K +ATP channels, α2-adrenoceptor, antioxidant activity (GSH, MPO and MDA), NO and mucosal cytokines (TNF-α, IL-1β, and IL-10) levels. RESULTS The chemical composition of HEFc was analyzed and apigenin, scutellarin, and carajurone were identified. HEFc (1, 5 and 20 mg/kg) showed effect against acute ulcers induced by HCl/EtOH with a reduction in the ulcerated area of 64.41% (p < 0.001), 54.23% (p < 0.01), 38.71% (p < 0.01), respectively. In the indomethacin experiment, there was no change in the doses tested, whereas in the water immersion restraint stress ulcer there was a reduction of lesions at doses of 1, 5, and 20 mg/kg by 80.34% (p < 0.001), 68.46% (p < 0.01) and 52.04% (p < 0.01). HEFc increased the mucus production at doses of 1 and 20 mg/kg in 28.14% (p < 0.05) and 38.36% (p < 0.01), respectively. In the pyloric ligation-induced model of gastric ulceration, the HEFc decreased the total acidity in all doses by 54.23%, 65.08%, and 44.40% (p < 0.05) and gastric secretory volume in 38.47% at dose of 1 mg/kg (p < 0,05) and increased the free acidity at the dose of 5 mg/kg by 11.86% (p < 0.05). The administration of EHFc (1 mg/kg) showed a gastroprotective effect possibly by stimulating the release of prostaglandins and activating K+ATP channels and α2-adrenoreceptors. Also, the gastroprotective effect of HEFc involved an increase in CAT and GSH activities, and a reduction in MPO activity and MDA levels. In the chronic gastric ulcer model, the HEFc (1, 5 and 20 mg/kg) decreased the ulcerated area significantly (p < 0.001) at all doses by 71.37%, 91.00%, and 93.46%, respectively. In the histological analysis, HEFc promoted the healing of gastric lesions by stimulating the formation of granulation tissue and consequently epithelialization. On the other hand, regarding the effect of HEFc on gastric emptying and intestinal transit, it was observed that the extract did not alter gastric emptying, but there was an increase in intestinal transit at the dose of 1 mg/kg (p < 0.01). CONCLUSION These outcomes confirmed the advantages of Fridericia chica leaves for the treatment of stomach ulcers, which are well-known. HEFc was discovered to have antiulcer characteristics through multitarget pathways, which might be related to an increase in stomach defense mechanisms and a decrease in defensive factor. HEFc can be regarded as a potential new antiulcer herbal remedy because of its antiulcer properties, which may be attributed to the mixture of flavonoids, apigenin, scutellarin and carajurone.

Abstract
BACKGROUND To better understand the efficacy and safety of Bifidobacterium quadruple viable tablets in the treatment of helicobacter pylori (H. pylori)-infected peptic ulcer or gastritis patients. METHODS A systematic review of the studies published to June 2022 was performed in English database PubMed, Embase, Chinese database CNKI, Wanfang. There were 17 studies were included in this systematic review and meta-analysis. The outcomes measured included H. pylori eradication rate, changes in clinical symptoms of epigastric pain scores, and the incidence of adverse reactions. RESULTS The results of the fixed effect model showed that the eradication rate of H. pylori in the combination of Bifidobacterium quadruple viable bacteria tablets combined with bismuth-containing conventional quadruple therapy was greater than that of bismuth-containing conventional quadruple therapy, and the difference was statistically significant (OR = 3.73, 95%CI (2.79,5.00), Z = 2.78, P < 0.001; I2 = 0.0%, P > 0.999). The results of random effects model showed that the epigastric pain score of Bifidobacterium quadruple viable bacteria tablets combined with bismuth-containing conventional quadruple therapy was lower than that of bismuth-containing conventional quadruple therapy, and the difference was statistically significant (WMD=-0.70, 95%CI (-1.06,-0.34), Z = 3.82, P < 0.001; I2 = 96.7%, P < 0.001). The results of random effects model showed that the acid reflux score of Bifidobacterium quadruple viable bacteria tablets combined with bismuth-containing conventional quadruple therapy was lower than that of bismuth-containing conventional quadruple therapy, and the difference was statistically significant (WMD=-0.98, 95%CI (-1.70,-0.26), Z = 2.66, P < 0.001; I2 = 99.7%, P < 0.001). CONCLUSIONS The eradication rate of H. pylori by Bifidobacterium quadruple viable bacteria tablets combined with bismuth-containing quadruple therapy is better than that of bismuth-containing quadruple therapy. The improvement of clinical symptoms of patients is better than that of bismuth-containing quadruple therapy, and the incidence of adverse reactions is lower than that of bismuth-containing quadruple therapy. Bifidobacterium quadruple viable bacteria tablet combined with bismuth-containing quadruple therapy was effective and safe. It provides a new way to treat patients with H. pylori.

Abstract
INTRODUCTION Whipple's disease is a rare systemic infection due to an impaired immunological response against T. whipplei in genetically predisposed individuals. Since we previously noted development of H. pylori related complications in some patients with Whipple's disease, our aim was to study the prevalence of H. pylori infection and H. pylori related disorders in Whipple's disease. METHODS Whipple's disease patients diagnosed from Jan-2002 to Dec-2021 and two controls per patient, matched for age, gender, ethnicity and year of H. pylori testing were enrolled. RESULTS 34 patients with Whipple's disease and 68 controls were enrolled. H. pylori infection (13/34 vs 8/68, p<0.01), H. pylori-related gastritis (p<0.01) and gastric atrophy (p = 0.01) were significantly more common in patients with Whipple's disease than controls. H. pylori infection and Whipple's disease were diagnosed synchronously in 6/13 patients, and during follow-up in the remaining 7. Interestingly, these last 7 patients were all on trimethoprim-sulfamethoxazole long-term therapy. Two patients developed H. pylori-related gastric malignancies during follow-up. No patients on doxycycline developed H. pylori infection. CONCLUSIONS H. pylori infection and related disorders are common in patients with Whipple's disease and should always be excluded both at time of diagnosis and during follow-up. These findings should be taken into account when selecting antibiotics for Whipple's disease long-term prophylaxis.

Abstract
Acute upper gastrointestinal bleeding (AUGIB) is a clinically common emergency condition. The common causes of AUGIB are peptic ulcer and esophagogastric variceal bleeding. Despite continuous improvements in endoscopic hemostasis techniques, endoscopic treatment is still unsuccessful in 5%-15% of patients. Hemostatic powder, a new drug for endoscopic hemostasis that is sprayed on the bleeding site with the assistance of an air pump, can absorb water to promote clotting substance aggregation and then adhere over the lesion, forming a mechanical barrier and then achieving hemostasis. It is convenient to spray hemostatic powder under endoscopy, where precise positioning is not warranted. The immediate hemostasis rate of hemostatic powder is often high, and it can be used as a remedy after the failure of conventional hemostasis. However, until now, there have been no recommendations in China regarding the use of hemostatic powder for the treatment of AUGIB. This article summarizes the mechanism, clinical applicability, and side effects of five major types of hemostatic powder by reviewing the existing evidence, with an aim to strengthen endoscopists' understanding of this drug.

Abstract
INTRODUCTION Refractory peptic ulcer is now a rare disease since most peptic ulcers heal with appropriate treatment with proton pump inhibitors (PPIs) and/or Helicobacter pylori eradication. AREAS COVERED The most frequent cause of apparent refractoriness is lack of adherence to treatment. Persistence of H. pylori infection, use or abuse (often surreptitious) of high dose non-steroidal anti-inflammatory drugs (NSAIDs) or aspirin (ASA) are the two major causes of true refractory ulcers. There is a growing number of peptic ulcers which are not linked to either NSAIDs or H. pylori infection. Refractoriness in these ulcers can be linked to gastric acid hypersecretion, rapid PPI metabolization, ischemia, chemo-radiotherapy, immune diseases, more rarely to other drugs or be fully idiopathic. Treatment of the cause of the ulcer, if known, is essential. This review is based on pertinent publications retrieved by a selective search in PubMed, with particular attention to refractory peptic ulcer. EXPERT OPINION High-dose PPI or the new potassium competitive acid blocker or the combination of PPIs with misoprostol can be recommended in these cases. Other more experimental treatment such the topical application of platelet- rich- plasma, or mesenchymal stem cells have also been suggested. Surgery is the last option, but there is no guarantee of success, especially in NSAID or ASA abusers.

Abstract
BACKGROUND Marginal ulcer bleeding (MUB) is a complication that can occur following several types of surgery. However, few studies exist on it. Therefore, this study aimed to compare the clinical outcomes of MUB with those of peptic ulcer bleeding (PUB). METHODS Between January 2013 and December 2017, 5,076 patients underwent emergent esophagogastroduodenoscopy for suspected upper gastrointestinal bleeding. We retrospectively reviewed and analyzed the medical records of MUB and PUB patients and developed a propensity score matching (PSM) method to adjust for between-group differences in baseline characteristics with 1:2 ratios. Sex, age, body mass index (BMI), underlying diseases, and drugs were included as matching factors. RESULTS A total of 64 and 678 patients were diagnosed with MUB and PUB, respectively, on emergent esophagogastroduodenoscopy, and 62 and 124 patients with MUB and PUB, respectively, were selected after PSM. Rebleeding was significantly higher in patients with MUB than in those with PUB (57.8% vs 9.1%, p < 0.001). Mortality caused by bleeding was higher in patients with MUB than in those with PUB (4.7% vs. 0.4%, p < 0.001). Multivariate analysis revealed that proton pump inhibitor (PPI) administration (odds ratio [OR], 0.14; 95% confidence interval [CI], 0.03-0.56; p = 0.011) after first bleeding was inversely correlated with MUB rebleeding. Large ulcer size (> 1 cm) (OR, 6.69; 95% CI, 1.95-27.94; p = 0.005) and surgery covering pancreas (OR, 3.97; 95% CI, 1.19-15.04) were independent risk factors for MUB rebleeding. CONCLUSIONS MUB showed a severe clinical course than PUB. Therefore, MUB should be managed more cautiously, especially for large ulcers and pancreatic surgery. Prophylactic PPI administration may be helpful in reducing rebleeding in MUB.

Abstract
Abstract Double pylorus is one of the rare endoscopic findings consisting of two communication channels between the gastric antrum and the first part of the duodenum. It has no specific signs and symptoms. It is usually detected incidentally during endoscopic examination performed with nonspecific dyspeptic complaints such as epigastric pain, nausea, vomiting, and bloating. But contrary to expectations our patient applied to the emergency department with the complaint of melena that had been going on for 3 days. Her hemoglobin value was 9.7 mg/dL, blood ure nitrogen value was 65 mg/dL. Rectal touch examination was compatible with melena. In the emergency endoscopy of the patient, two channels were seen in the pylorus region. In the accessory canal, there was an ulcer of 10 mm in size with adherent dots and white exudate. The biopsy was reported as chronic gastritis due to H.pylori infection. Ibuprofen treatment used by the patient was discontinued and the patient was given high double dose PPI and H.pylori eradication therapy. Double pylorus, which is usually found incidentally in endoscopy with nonspecific findings, may very rarely present with GI bleeding findings, as in our patient. It is necessary to avoid risk factors in double pylorus, to give antiulcer and H.pylori treatment in its presence for an optimal time regardless of whether the double pylorus continues or not.

Abstract
Proton pump inhibitors (PPIs) have several limitations to their efficacy including insufficient acid suppression, slow onset of action, and variable efficacy among patients due to CYP2C19 metabolism. Potassium-competitive acid blockers inhibit H+-K+-ATPase in a reversible and K+-competitive manner, are novel acid suppressive drugs with rapid onset of action, meal independence, and prolonged control of intragastric acidity compared to PPIs. Potassium-competitive acid blockers exhibited non-inferior therapeutic efficacies on reflux esophagitis, gastric ulcers, and Helicobacter pylori eradication. The review is focused on the unmet needs across the acid-related diseases and recent updates on clinical studies using vonoprazan and tegoprazan.

Abstract
BACKGROUND An ulcer is a condition characterized by inflammation, irritation, or erosion in the mucosal lining of the stomach or duodenum. Hence, peptic ulcer is the ulcer of both the stomach and the duodenum. 10% of the world's population is affected by chronic peptic ulcers. The formation of peptic ulcers depends on gastric juice pH and the decrease in mucosal defenses. Nonsteroidal anti-inflammatory drugs (NSAIDs) and Helicobacter pylori (H. pylori) infection are the two significant factors disrupting mucosal resistance to injury. Indian herbal plants are exceptional for their ethnic, ethnobotanical, and ethno-pharmaceutical use. In this review, attempts have been made to gain information regarding some plants that may be used to treat or prevent peptic ulcers. The ultimate goal of peptic ulcer disease treatment is to reduce pain, cure ulcers, and prevent recurrence. OBJECTIVE The aim of the study was to gain knowledge about several common medicinal plants employed in Ayurveda or contemporary science for the treatment or prevention of peptic ulcers and some natural and simple approaches to cure ulcers using readily available herbs. METHOD The literature search was carried out using search engines, like Google Scholar, Scopus, PubMed, Medline, Springer, etc. Results: The extensive literature search showed natural herbs to have potential anti-ulcer activity, including cabbage, bananas, liquorice, fenugreek, garlic, Terminalia chebula, Acacia arabica, Aegle marmelos, Aloe vera, Allium sativum, Plantago ispagula, Mimosa pudica, Annona squamosa, Azadirachta indica, and Galega purpurea. CONCLUSION This study concluded several medicinal plants to effectively prevent or cure peptic ulcers caused by a variety of factors, including H. pylori, aspirin, indomethacin, alcohol, and others.

[PMID: 36570627 PMCID: PMC9768370 DOI: 10.1016/j.sopen.2022.11.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Revised: 11/10/2022] [Accepted: 11/30/2022] [Indexed: 12/12/2022] Open
Abstract
Background The study aimed to calculate the predictive value of admission laboratory values in patients with perforated peptic ulcers. Methods A retrospective, cohort analytical, observational study was performed, including patients with surgically confirmed perforated peptic ulcers over a 5-year period. Demographic data and admission laboratory values were collected from hospital electronic databases. Outcomes measured were in-hospital mortality, intensive care unit (ICU) admission and length of stay. The significance of categorical variables was calculated by chi-square and Fisher's exact test. Logistic regression analysis was performed to determine univariately statistically significant variables. Results In total, 188 patients met the inclusion criteria. The median age was 46 (range 15-87) years with a male predominance of 71.3 % (n = 134). The median length of hospital stay was 7 (range 1-94) days and 31.4 % (n = 59) of patients were admitted to the ICU. Post-operative in-hospital mortality was 25.0 % (n = 47). Predicting the categorical outcome of in-hospital mortality, abnormal haemoglobin, platelet count, urea, creatinine and potassium levels were all found to be statistically significant in the univariate analysis. Age (odds ratio [OR] 1.03), haemoglobin (OR 4.36) and creatinine (OR 7.76) levels were significant in the multivariate analysis. Conclusions Mortality rate among patients with perforated peptic ulcer disease is still substantial. Admission laboratory values showed statistical significance as outcome indicators and were valuable to assist in predicting the prognosis. An abnormally high serum creatinine level was the strongest single predictor of both mortality and ICU admission. Key message Initial laboratory findings of patients admitted for perforated peptic ulcer showed that an abnormally high serum creatinine level was the strongest single predictor of both mortality and ICU admission.

[PMID: 36579108 PMCID: PMC9791504 DOI: 10.12998/wjcc.v10.i34.12775] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Revised: 11/03/2022] [Accepted: 11/08/2022] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND A perforated gastroduodenal ulcer is rarely observed in children. Certain medications have been reported to cause ulcerations. Deferasirox, an iron chelating agent, has been previously reported to be associated with the development of gastroduodenal ulcers.
CASE SUMMARY We report a case of a 3-year-old boy who was diagnosed with beta thalassemia major and treated with deferasirox. He presented to the emergency department with an acute abdomen. A perforated duodenal ulcer was suspected after X-ray imaging and laparoscopic exploration. It was successfully managed with laparoscopic washout and drainage.
CONCLUSION Due to the rarity and severity of this case, it is a reminder that prevention and early recognition of gastrointestinal complications in patients receiving deferasirox are crucial. Minimally invasive laparoscopic surgery is both safe and feasible to treat perforated duodenal ulcers in selected patients.

Abstract
BACKGROUND The ability of endoscopists to identify gastric lesions is uneven. Even experienced endoscopists may miss or misdiagnose lesions due to heavy workload or fatigue or subtle changes in lesions under white-light endoscopy (WLE). This study aimed to develop an artificial intelligence (AI) system that could diagnose six common gastric lesions under WLE and to explore its role in assisting endoscopists in diagnosis. METHODS Images of early gastric cancer, advanced gastric cancer, submucosal tumor, polyp, peptic ulcer, erosion, and lesion-free gastric mucosa were retrospectively collected to train and test the system. The performance of the system was compared with that of 12 endoscopists. The performance of endoscopists with or without referring to the system was also evaluated. RESULTS A total of 29,809 images from 8947 patients and 1579 images from 496 patients were used to train and test the system, respectively. For per-lesion analysis, the overall accuracy of the system was 85.7%, which was comparable to that of senior endoscopists (85.1%, P = 0.729) and significantly higher than that of junior endoscopists (78.8%, P < 0.001). With system assistance, the overall accuracies of senior and junior endoscopists increased to 89.3% (4.2%, P < 0.001) and 86.2% (7.4%, P < 0.001), respectively. Senior and junior endoscopists achieved varying degrees of improvement in the diagnostic performance of other types of lesions except for polyp. The diagnostic times of senior (3.8 vs 3.2 s per image, P = 0.500) and junior endoscopists (6.2 vs 4.6 s per image, P = 0.144) assisted by the system were both slightly shortened, despite no significant differences. CONCLUSIONS The proposed AI system could be applied as an auxiliary tool to reduce the workload of endoscopists and improve the diagnostic accuracy of gastric lesions.

Abstract
BACKGROUND Helicobacter pylori eradication is associated with reduced gastric cancer and peptic ulcer disease incidence and mortality. Factors influencing patients' experiences surrounding H. pylori diagnosis and management are not well-described. Current patient perceptions can influence adherence to treatment, and also their anxieties related to this potentially carcinogenic condition. The objective of this study was to understand the patient experience surrounding H. pylori management and to qualitatively construct a contextual framework to inform and guide providers who manage patients with H. pylori infection. METHODS We conducted a qualitative analysis using a focus group and one-on-one telephone interviews. An iterative inductive/deductive approach was applied to recorded transcripts to identify and hierarchically order themes. Patient experience was defined according to major themes within a structured health behavior framework. RESULTS Theme saturation was achieved with thirteen participants (mean age 50.4 years; 62% female; 38% non-Hispanic white). Qualitative analysis yielded a total of 987 codes that resulted in five major themes related to the patient H. pylori experience: context of decision-making; health beliefs; barriers experienced; cues to action; and impact of new knowledge. These themes aligned with the Health Behavior Model framework. Participants were motivated to treat H. pylori. However, the experience was more often perceived negatively versus positively. The perceived patient-provider interaction contributed most prominently to the negative experience compared to other patient experiences, including treatment-related side effects. Internal cues, including symptoms and fear of cancer, modified participants' perceptions and motivation to accept treatment. CONCLUSIONS Patient experiences related to H. pylori management are predominantly negative. Increasing providers' awareness about patients' values, beliefs, anxieties, and expectations surrounding H. pylori diagnosis/treatment may improve provider-patient communication and, ideally, related outcomes.

Wang JX, Soh LS, Mahendran DCJ, Woon CY, Chia CLK. Rare case of perforated giant gastric ulcer with concurrent thyroid storm: A case report. World J Surg Proced 2022; 12:8-12. [DOI: 10.5412/wjsp.v12.i1.8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Revised: 03/27/2022] [Accepted: 04/21/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Thyroid storm is an uncommon condition manifesting in severe thyrotoxicosis with a high mortality rate. The concurrence of peptic ulcer disease and hyperthyroidism is rare due to concurrent activation of both the sympathetic and parasympathetic pathways. We present a case of perforated giant gastric ulcer with concurrent thyroid storm who underwent damage control surgery with emergency patch repair with falciform ligament and recovered well.
CASE SUMMARY A 53-year-old male chronic smoker, with no previous medical history, presented with severe generalized abdominal pain and vomiting for one day duration. Further history revealed weight loss, diarrhea, and anxiety over the past three months. On clinical examination, patient was febrile with temperature of 38.6 Degrees Celsius and tachycardic at 130-140 beats per minute, his blood pressure was low at 90/50mmHg. His abdomen was tender with generalized peritonism. In view of his clinical history, a thyroid screen was ordered which showed raised thyroxine (T4) levels of 90.3 pmol/L and low thyroxine stimulating hormone (TSH) levels of 0.005 μU/mL. Chest X-ray showed no sub-diaphragmatic free air, but contrasted CT scan revealed pneumoperitoneum with large amount of intraabdominal free fluid. The working diagnosis was perforated peptic ulcer complicated by thyroid storm. An urgent endocrinologist consult was made, and patient was started on beta blocker and intravenous steroids pre-operatively. The patient underwent emergency laparotomy with washout and patch repair of the perforated gastric ulcer. Patient was monitored post-operatively in intensive care unit and required IV hydrocortisone and Lugol’s iodine. Histology of the ulcer edges showed no malignancy. On post-operative day seven, T4 decreased to 20.4 pmol/L, TSH was 0.005 mLU/L. His thyroid function test subsequently normalized 3 mo post-operatively with T4 18.1 pmol/L, TSH 1.91 mLU/L. Patient’s recovery was otherwise uneventful. Thyroid receptor antibody subsequently was positive, and patient was managed for Grave’s disease by the endocrinologist.
CONCLUSION This case highlights the rare but life-threatening clinical emergency of peptic ulcer perforation complicated by thyroid storm. Multidisciplinary perioperative management is crucial to optimize patient for surgery and damage control principles should be taken for an acute surgical patient with concurrent endocrine crisis.

Abstract
Gastroduodenal inflammation and ulcerative injuries are increasing due to expanding socio-economic stress, unhealthy food habits-lifestyle, smoking, alcoholism and usage of medicines like non-steroidal anti-inflammatory drugs. In fact, gastrointestinal (GI) complications, associated with the prevailing COVID-19 pandemic, further, poses a challenge to global healthcare towards safeguarding the GI tract. Emerging evidences have discretely identified mitochondrial dysfunctions as common etiological denominators in diseases. However, it is worth realizing that mitochondrial dysfunctions are not just consequences of diseases. Rather, damaged mitochondria severely aggravate the pathogenesis thereby qualifying as perpetrable factors worth of prophylactic and therapeutic targeting. Oxidative and nitrosative stress due to endogenous and exogenous stimuli triggers mitochondrial injury causing production of mitochondrial damage associated molecular patterns (mtDAMPs), which, in a feed-forward loop, inflicts inflammatory tissue damage. Mitochondrial structural dynamics and mitophagy are crucial quality control parameters determining the extent of mitopathology and disease outcomes. Interestingly, apart from endogenous factors, mitochondria also crosstalk and in turn get detrimentally affected by gut pathobionts colonized during luminal dysbiosis. Although mitopathology is documented in various pre-clinical/clinical studies, a comprehensive account appreciating the mitochondrial basis of GI mucosal pathologies is largely lacking. Here we critically discuss the molecular events impinging on mitochondria along with the interplay of mitochondria-derived factors in fueling mucosal pathogenesis. We specifically emphasize on the potential role of aberrant mitochondrial dynamics, anomalous mitophagy, mitochondrial lipoxidation and ferroptosis as emerging regulators of GI mucosal pathogenesis. We finally discuss about the prospect of mitochondrial targeting for next-generation drug discovery against GI disorders.

Abstract
Background Perforated peptic ulcer (PPU) is a common emergency condition requiring surgery using laparoscopy or open repair of the perforated site. The aim of this study was to assess the role of laparoscopic surgery (LS) based on the safety and efficacy for PPU. Methods Medical records of the consecutive patients who underwent LS or open surgery (OS) for PPU at five hospitals between January 2009 and December 2019 were retrospectively reviewed. After propensity score matching, short-term perioperative outcomes were compared between LS and OS in selected patients. Results Among the 598 patients included in the analysis, OS was more frequently performed in patients with worse factors, including older age, a higher American Society of Anesthesiologists score, more alcohol use, longer symptom duration, a higher Boey score, a higher serum C-reactive protein level, a lower serum albumin level, and a larger-diameter perforated site. After propensity score matching, 183 patients were included in each group; variables were well-balanced between-groups. Postoperative complications were not different between groups (24.6% LS group vs. 31.7% OS group, p = 0.131). However, postoperative length of hospital stay (10.03 vs. 12.53 days, respectively, p = 0.003) and postoperative time to liquid intake (3.75 vs. 5.26 days, p < 0.001) were shorter in the LS group. Conclusions LS resulted in better functional recovery than OS and can be safely performed for treatment of PPU. When performed by experienced surgeons, LS is an alternative option, even for hemodynamically unstable patients.

Abstract
UNLABELLED Oral bisphosphonates and direct oral anticoagulants are related to upper gastrointestinal ulcers. The present study investigated whether concomitant use of these drugs increase the risk of upper gastrointestinal ulcers and report no increased risk of upper gastrointestinal ulcers compared to the use of either drug alone, when individuals with previous upper gastrointestinal ulcers are excluded. INTRODUCTION This study examines whether concomitant use of oral bisphosphonates (oBP) and direct oral anticoagulants (DOAC) increases the risk of peptic ulcers more than any drug alone. METHODS A population-based cohort study was performed. We sampled a cohort of oBP and DOAC users from a sample of 2,622,742 individuals, consisting of diabetes patients and age- and gender-matched controls, obtained from the Danish National Patient Register. The exposures were concomitant use of oBP and DOAC and single use of DOAC and single use of oBP. The primary endpoint was the first incident peptic ulcer. Information on exposure and outcome were collected from national registries. The period of observation was from 01.01.2008 until 31.12.2018. Unadjusted and adjusted Cox regressions were performed. RESULTS 8077 individuals received concomitant treatment with DOAC and oBP; 96,451 individuals used DOAC and no oBP; and 118,675 used oBP and no DOAC. The mean duration of follow-up was 1.9 years for concomitant users, 2.5 years for DOAC users, and 4.5 years for oBP users. A total of 4742 individuals with incident peptic ulcers were collected. We observed an increased risk of incident ulcer in users of DOAC and oBP compared to single DOAC treatment in the adjusted analysis (HR = 1.23, 95% CI: 1.03; 1.48). However, the effects were abolished when excluding individuals with a previous ulcer. We observed an increased risk of incident ulcer in users of DOAC and oBP compared to users of oBP in the adjusted model (HR = 1.34, 95% CI: 1.11; 1.63). CONCLUSION Based on our results, concomitant use of oBP and DOAC is associated with a slight increase in the risk of peptic ulcers compared to either drug alone. The prescribing physician should weigh the slight increased risk of ulcer in concomitant users of oBP and DOAC with beneficial reductions in stroke and fractures.

Abstract
BACKGROUND Peptic ulcer perforation is a common life-threatening surgical emergency. Graham omental patch is performed for plugging of perforated peptic ulcer. Many endoscopic methods have been used to treat acute perforated peptic ulcer such as over the scope clips, standard endoscopic clips, endoscopic sewing and metallic stents. The main idea in endoscopic management of acute perforated peptic ulcer is early decontamination and decrease sepsis by interventional radiologic drainage. METHODS This is a prospective randomized controlled clinical trial. This study included patients who were developed acute perforated peptic ulcer manifestations and were admitted to our hospital between December 2019 and August 2021. Sample size was 100 patients divided into 2 equal groups. Endoscopic group (EG): included 50 patients who were subjected to endoscopic management. Surgical group (SG): included 50 patients who were subjected to surgical management. RESULTS One hundred patients were randomized into 2 groups: SG (50) and EG (50). Median age of patients was 36 (range 27:54) and 47 (range 41:50) years-old in SG and EG, respectively. Males constituted 72% and 66% in SG and EG, respectively. Median length of postoperative hospital stay was 1 (range: 1-2) days in EG, while in SG was 7 (range 6-8) days. Postoperative complications in SG patients were 58% in form of fever, pneumonia, leak, abdominal abscess, renal failure and incisional hernia (11%, 5%, 5%, 3%, 2% and 3%, respectively). Postoperative complications in EG patients were 24% in form of fever, pneumonia, leak, abdominal abscess, renal failure and incisional hernia (10%, 0%, 2%, 0%, 0% and 0%, respectively). CONCLUSION Combined endoscopic and interventional radiological drainage can effectively manage acute perforated peptic ulcer without the need for general anesthesia, with short operative time, in high risk surgical patients with low incidence of morbidity & mortality.

Abstract
Annular pancreas is a rare congenital anomaly in which a thin band of pancreatic tissue partially or completely surrounds the duodenum. It is challenging to diagnose due to its variable clinical presentation. Approximately two-thirds of patients have no symptoms in their lifetime, and most symptomatic cases are seen in neonates and infants. Symptomatic adult patients present with upper gastrointestinal symptoms, such as epigastric pain, vomiting, and postprandial fullness associated with gastric outlet obstruction. Complications associated with annular pancreas include peptic ulcer disease, pancreatitis, pancreatic head carcinoma, and biliary obstruction. Annular pancreas is also a rare cause of upper gastrointestinal bleeding in adults, but it should be considered as one of the differential diagnoses in patients presenting with a peptic ulcer and duodenal stricture. Here, we report the case of a 60-year-old man who presented with melena and was subsequently diagnosed with an annular pancreas.

Abstract
Found in humid regions and waterways and popularly used to treat gastrointestinal problems among other applications, the present study evaluated the M. aquatica essential oil (OEMa) as a therapeutic alternative to treat gastrointestinal disorders. Produced by steam distillation, chemical composition of OEMa was determined by GC-MS analysis. The ethanol-induced ulcer and the dose-repeated acetylsalicylic acid (ASA)-induced gastrointestinal lesions models in rats evaluated, respectively, the prophylactic and curative effects of EOMa on peptic ulcers. The EOMa's effect on gastric secretion, gastric mucus and gastrointestinal motility were evaluated in in vivo models. The curative effect of EOMa on acute colitis was evaluated using the DSS-induced colitis model in mice. Obtained in 0.17% yield (w/w), with carvone (54.82 ± 1.39 g/100 g oil) as the main constituent, EOMa (at 75 mg/kg) showed potent gastroprotective effect (> 90%) mediated by non-protein sulfhydryl compounds (NPSH) and nitric oxide (NO) modulation alongside reduction in gastric secretion volume and total acidity. EOMa did not affect gastric mucus production and gastrointestinal motility. In dose-repeated ASA-induced gastrointestinal lesions model, EOMa (at 25 mg/kg) promoted the inflammatory process resolution both in gastric and duodenal walls by modulating NPSH, NO and myeloperoxidase levels. Despite delaying in 2 days the clinical symptoms worsening, EOMa (at 25 mg/kg) was not able to protect colon tissues from DSS-induced acute colitis as evidenced by macroscopic, biochemical, and histopathological parameters. This is the first report of Mentha aquatica essential oil as a promising herbal medicine for peptic ulcers treatment together with an adjuvant effect in IBD.

World J Gastrointest Endosc 2022; 14:163-175. [PMID: 35432740 PMCID: PMC8984531 DOI: 10.4253/wjge.v14.i3.163] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2021] [Revised: 10/08/2021] [Accepted: 02/10/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Acute non-variceal bleeding accounts for approximately 20% of all-cause bleeding episodes in patients with liver cirrhosis. It is associated with high morbidity and mortality therefore prompt diagnosis and endoscopic management are crucial.
AIM To evaluate available data on the efficacy of endoscopic treatment modalities used to control acute non-variceal gastrointestinal bleeding (GIB) in cirrhotic patients as well as to assess treatment outcomes.
METHODS Employing PRISMA methodology, the MEDLINE was searched through PubMed using appropriate MeSH terms. Data are reported in a summative manner and separately for each major non-variceal cause of bleeding.
RESULTS Overall, 23 studies were identified with a total of 1288 cirrhotic patients of whom 958/1288 underwent endoscopic therapy for acute non-variceal GIB. Peptic ulcer bleeding was the most common cause of acute non-variceal bleeding, followed by portal hypertensive gastropathy, gastric antral vascular ectasia, Mallory-Weiss syndrome, Dieaulafoy lesions, portal hypertensive colopathy, and hemorrhoids. Failure to control bleeding from all-causes of non-variceal GIB accounted for less than 3.5% of cirrhotic patients. Rebleeding (range 2%-25%) and mortality (range 3%-40%) rates varied, presumably due to study heterogeneity. Rebleeding was usually managed endoscopically and salvage therapy using arterial embolisation or surgery was undertaken in very few cases. Mortality was usually associated with liver function deterioration and other organ failure or infections rather than uncontrolled bleeding. Endoscopic treatment-related complications were extremely rare. Lower acute non-variceal bleeding was examined in two studies (197/1288 patients) achieving initial hemostasis in all patients using argon plasma coagulation for portal hypertensive colopathy and endoscopic band ligation or sclerotherapy for bleeding hemorrhoids (rebleeding range 10%-13%). Data on the efficacy of endoscopic therapy of cirrhotic patients vs non-cirrhotic controls with acute GIB are very scarce.
CONCLUSION Endotherapy seems to be efficient as a means to control non-variceal hemorrhage in cirrhosis, although published data are very limited, particularly those comparing cirrhotics with non-cirrhotics and those regarding acute bleeding from the lower gastrointestinal tract. Rebleeding and mortality rates appear to be relatively high, although firm conclusions may not be drawn due to study heterogeneity. Hopefully this review may stimulate further research on this subject and help clinicians administer optimal endoscopic therapy for cirrhotic patients.
