PURPOSE
In this case we report a rare presentation of a ruptured gastroduodenal artery aneurysm (GDA) accompanied by a duodenal perforation. It contributes to the scientific literature by discussing the management approach and results in a patient with dual complications and emphasizes the importance of early diagnosis and appropriate treatment.
CASE PRESENTATION
A 50-year-old male presented with severe abdominal pain, anemia, and signs of hemodynamic instability. Diagnostic imaging including CTA revealed a large, thrombosed gastroduodenal artery aneurysm with evidence of rupture. The patient underwent open surgical exploration and repair to address both the aneurysm and the duodenal perforation. The patient's recovery was satisfactory and was discharged home in stable condition.
CONCLUSION
Early diagnosis and appropriate management in gastroduodenal artery aneurysms is crucial. There is a need for individualized surgical interventions based on the patient's hemodynamic status and associated complications. Dual complications required open surgical exploration and repair, resulting in favorable outcomes.

Observational Study
To explore the relationships between gastrointestinal radiation injuries of pancreatic cancer patients treated with TOMO and dose-volume histogram parameters prospectively. Seventy patients with pancreatic cancer who underwent TOMO were enrolled in this prospective study from February 2015 to May 2020. The clinical and dose-volume histogram parameters of the patients were collected. The optimal dose parameters for gastrointestinal radiation ulcers were confirmed based on the receiver operating characteristic curve (ROC) and the area below the ROC curve. Acute gastrointestinal tract toxic and side effect and injury grading correlation analyzed by Kruskal-Wallis rank sum test. Gastrointestinal injury often occurs during radiotherapy for pancreatic cancer, as observed using gastroscopy. The main adverse reactions were radioactive gastrointestinal inflammation (58.5%), radioactive gastrointestinal ulcers (41.4%), active bleeding (10%), newly-developed gastric retention (8.6%), and gastric varices (5.7%). As for the stomach, Dmean and V10 were related to radiation ulcer injury. ROC curve indicated that for stomach a Dmean of 13.39 Gy (area under ROC curves = 0.74, P = .048) and a V10 of 72.21% (area = 0.74, P = .048) was the tolerated dose for the injury of stomach radiation ulcer. As for duodenum, aV20 and aV25 are related to radiation ulcer injury. ROC curve indicated that aV20 of 22.82 cm3 (area = 0.68, P = .025) and aV25 of 32.04 cm3 (area = 0.66, P < .047) was the tolerated dose for the injury of duodenum radiation ulcer. The acute gastrointestinal tract toxic and side effects have no significant correlation with injury grading under gastroscope. Dmean > 13.39 Gy and V10 > 72.21% were the key dosimetric indices for predicting radiation-induced gastric ulcer, and aV20 > 22.82 cm3 and aV25 > 32.04 cm3 were for duodenal. Gastrointestinal reactions cannot be used as an overall basis for the diagnosis of gastrointestinal injury, and gastroscopy is recommended as a review item after radiotherapy.

Perforated peptic ulcers, though relatively rare, represent critical surgical emergencies with potentially life-threatening consequences. Their significance lies not only in their acute presentation but also in the diagnostic challenges they pose, particularly in patients with complex medical histories. Here we present a case of a 71-year-old female with a complex medical history, including insulin-dependent type 2 diabetes mellitus, hypertension, hyperlipidemia, hypothyroidism, dementia, diverticulitis, and chronic back pain, who initially were unresponsive and cyanotic. Despite challenges in diagnosis due to her medical complexity and opioid use, she was ultimately diagnosed with a perforated duodenal ulcer. Tragically, despite immediate surgical intervention, she succumbed to her illness, highlighting the complexities involved in managing perforated peptic ulcers, especially in patients with multiple chronic medical conditions. Peptic ulcer disease (PUD) can often remain asymptomatic, leading to delayed diagnosis and potentially life-threatening complications like perforation. Mortality rates associated with perforated peptic ulcers vary widely, ranging from 1.3% to 20%, with risk factors including nonsteroidal anti-inflammatory drug (NSAID) use, infection, smoking, and corticosteroid use. Diagnosis necessitates a high index of suspicion, thorough clinical examination, and imaging modalities such as computed tomography (CT) scans with oral contrast. Treatment strategies range from nonoperative management with intravenous (IV) histamine H2-receptor blockers or proton pump inhibitors (PPIs) to surgical intervention, depending on the patient's hemodynamic stability. However, the case presented underscores the challenges in timely diagnosis and intervention, particularly in patients with complex medical histories, where symptoms may be masked or attributed to other comorbidities. Recent studies indicate a demographic shift toward older age and a higher prevalence among females, emphasizing the importance of increased awareness and vigilance among healthcare providers. Early recognition of symptoms, prompt investigation, and interdisciplinary collaboration are crucial in optimizing outcomes for patients presenting with perforated peptic ulcers, especially in the context of their underlying medical conditions.

BACKGROUND The Over-the-Scope-Clip (OTSC) System is a class of endoscopic clips intended to provide improved strength and tissue capture compared to conventional through-the-scope clips. These clips are generally safe and effective in managing many gastrointestinal conditions, with a low overall adverse event rate. Although the OTSC has been used to treat gastrointestinal bleeding and bowel perforations for many years, it often is relegated to second-line therapy and has only recently become a first-line hemostatic therapy for gastrointestinal bleeding. CASE REPORT Here, we present a unique adverse event of the OTSC causing iatrogenic ligation of the gastroduodenal artery (GDA). A 71-year-old man presented with 6 months of epigastric abdominal pain and 2 weeks of hematemesis, and was ultimately diagnosed with a bleeding duodenal ulcer. He underwent multiple endoscopic interventions to attempt to control the duodenal ulcer bleeding, including placement of the OTSC on a visible vessel. Soon after OTSC placement, he became hypotensive with recurrent hematochezia, and Interventional Radiology was consulted for endovascular management of the bleeding. Angiography showed the OTSC had been deployed across the midportion of the GDA from the duodenal lumen, effectively ligating the GDA, causing bleeding due to direct vascular injury. This bleeding was ultimately controlled with coil embolization. However, this iatrogenic ligation of the midportion of the GDA by the OTSC significantly complicated endovascular intervention to control the bleeding. CONCLUSIONS As the OTSC device becomes more commonly used in the endoscopy suite, it is important to share potential pitfalls that may be encountered in the clinical setting that impact not only endoscopists and patients, but other specialties as well.

BACKGROUND/AIM
Helicobacter pylori (H. pylori) colonization affects the gastric microbiome, causing gastrointestinal (GI) diseases. Modern sequencing technology provides insights into GI microbe interaction with H. pylori and their metabolic pathways in causing GI diseases. We aim to compare the gastric microbiota alteration due to H. pylori infection in patients suffering from GI diseases.
MATERIALS AND METHODS
Genomic DNA were isolated from gastric antrum tissue from 37 H.pylori-infected patients diagnosed with GERD, duodenal ulcers, and gastritis. We conducted the genomic library preparation and sequencing of the amplified product using 16S rRNA NGS analysis. Using microbiome analyst tool diversity analysis, random forest analysis and ANOVA were conducted to find out the comparison of microbial abundance. We have also conducted functional pathway prediction analysis using PICRUSt.
RESULTS
Metagenomic analysis shows high bacterial diversity in H. pylori-positive gastritis patients. Streptococcus infantis and Neisseria subflava were significantly higher in duodenal ulcer (DU) and gastritis groups. Acinetobacter lwoffii and Helicobacter pullorum were significantly high in the gastritis group only. The functional metabolic pathway analyses revealed that gastroesophageal reflux disease (GERD) samples were significantly enriched with the energy metabolism and xenobiotic biodegradation and metabolism pathways, whereas fructose-1,6-bisphosphatase III was found less in gastritis and DU groups.
CONCLUSION
There is a difference in microbiota composition in different disease outcomes. We found positive association between microbial diversity and H. pylori in gastritis group only, whereas negative association was found in DU and GERD groups. The functional metabolic pathway analysis revealed significant differences in various disease outcomes.

In the context of mediastinal emphysema/pneumomediastinum, the main aetiologies are associated with oesophageal perforation, lung pathology or post head and neck surgery related. The main way to differentiate the pathologies would be through Computed Tomographic Imaging of the Thorax and abdomen with oral and intravenous contrast in the context of triple phase imaging. The causes of pneumomediastinum should be differentiated between traumatic and non-traumatic. Oesophageal perforation (Boerhaave syndrome) is associated with Mackler's triad in upto 50% of patients (severe retrosternal chest pain, pneumomediastinum, mediastinitis). Whereas in cases of lung pathology this can be associated with pneumothorax and pleural effusion.

Acute cholecystitis is an inflammatory condition of the gallbladder, characterized by infection, ulceration, and neutrophilic infiltration of the gallbladder wall. Approximately 90% of cases are caused by gallstones. In contrast, acalculous cholecystitis is defined as the inflammation of the gallbladder in the absence of gallstones during diagnosis. The causes of acalculous cholecystitis include impaired blood flow to the gallbladder, chemical injury, bacterial or parasitic infections, and collagen vascular diseases. However, in this case, it was caused by an extremely rare condition: a duodenal ulcer penetration. Physical examination, blood tests, and ultrasound suggested a diagnosis of acute cholecystitis. However, contrast-enhanced CT showed no gallstones and revealed a partial mucosal defect in the first portion of the anterior duodenum. There was also wall thickening and increased density of the surrounding fat tissue, particularly around the gallbladder wall adjacent to the first portion of the anterior duodenum. Based on these findings, secondary cholecystitis due to perforation of a duodenal ulcer was diagnosed, and laparoscopic cholecystectomy with omental patching was performed. Although rare, a duodenal ulcer should be considered as a cause of acalculous cholecystitis.

BACKGROUND
Proton-pump inhibitors (PPIs) prevent aspirin-associated gastric and duodenal mucosal damage. However, long-term use of PPIs can lead to various adverse reactions, such as gastric polyps and enterochromaffin-like cell hyperplasia. Current research indicates that the abovementioned adverse reactions are mainly related to hypergastrinemia. We investigated whether low-frequency administration of omeprazole could effectively repair aspirin-induced mucosal damage and reduce the increase in gastrin levels associated with long-term use of PPIs.
METHODS
Sprague‒Dawley rats were divided into four treatment groups: daily aspirin, daily aspirin and omeprazole once every day (qd), daily aspirin and omeprazole once every other day (qod), and daily aspirin and omeprazole once every three days (1/d3). After 15 days of feeding, blood samples were collected, and the stomachs of sacrificed rats were subjected to macroscopic, histological, and immunohistochemical studies. Moreover, in clinical practice, patients with peptic ulcers caused by aspirin took a standard dose of omeprazole (20 mg) every other day. Two months later, gastroscopy was performed to examine the healing of the ulcers.
RESULTS
Both the omeprazole qd and omeprazole qod administrations effectively prevented aspirin-induced gastric peptic ulcers, with no significant difference between the two groups in the inhibition of parietal cell secretion of gastric acid and cell apoptosis. However, omeprazole 1/d3 failed to completely prevent aspirin-induced gastric mucosal injury. Notably, the gastrin levels, cell proliferation ability and cholecystokinin B receptor expression of the omeprazole qd group were significantly higher than those of the omeprazole qod group. In clinical work, patients with peptic ulcers caused by aspirin were given a standard dose of omeprazole every other day, and their ulcers healed after 2 months, as observed by gastroscopy.
CONCLUSIONS
Omeprazole administration once every other day can effectively prevent aspirin-induced peptic ulcers and reduce hypergastrinemia, which may reduce the long-term adverse effects of PPI treatment.

(-)-Fenchone Prevents Cysteamine-Induced Duodenal Ulcers and Accelerates Healing Promoting Re-Epithelialization of Gastric Ulcers in Rats via Antioxidant and Immunomodulatory Mechanisms.
BACKGROUND
(-)-Fenchone is a naturally occurring monoterpene found in the essential oils of Mill., L., and Molina. Pharmacological studies have reported its antinociceptive, antimicrobial, anti-inflammatory, antidiarrheal, and antioxidant activities.
METHODS
The preventive antiulcer effects of (-)-Fenchone were assessed through oral pretreatment in cysteamine-induced duodenal lesion models. Gastric healing, the underlying mechanisms, and toxicity after repeated doses were evaluated using the acetic acid-induced gastric ulcer rat model with oral treatment administered for 14 days.
RESULTS
In the cysteamine-induced duodenal ulcer model, fenchone (37.5-300 mg/kg) significantly decreased the ulcer area and prevented lesion formation. In the acetic acid-induced ulcer model, fenchone (150 mg/kg) reduced ( < 0.001) ulcerative injury. These effects were associated with increased levels of reduced glutathione (GSH), superoxide dismutase (SOD), interleukin (IL)-10, and transforming growth factor-beta (TGF-β). Furthermore, treatment with (-)-Fenchone (150 mg/kg) significantly reduced ( < 0.001) malondialdehyde (MDA), myeloperoxidase (MPO), interleukin-1 beta (IL-1β), tumor necrosis factor-alpha (TNF-α), and nuclear transcription factor kappa B (NF-κB). A 14-day oral toxicity investigation revealed no alterations in heart, liver, spleen, or kidney weight, nor in the biochemical and hematological parameters assessed. (-)-Fenchone protected animals from body weight loss while maintaining feed and water intake.
CONCLUSION
(-)-Fenchone exhibits low toxicity, prevents duodenal ulcers, and enhances gastric healing activities. Antioxidant and immunomodulatory properties appear to be involved in its therapeutic effects.
