Polyarteritis nodosa presenting with severe upper gastrointestinal bleeding: a case report.

Background: Polyarteritis nodosa is a relatively uncommon type of systemic necrotizing vasculitis that primarily affects medium-sized arteries. While gastrointestinal involvement is known in polyarteritis nodosa, heavy gastrointestinal bleeding due to gastric ulceration is relatively uncommon. We present the case of an 81-year-old male of Chinese ethnicity who experienced severe gastrointestinal bleeding as a result of polyarteritis nodosa and an innovative treatment approach for a better patient outcomes.

Intense fibroblast activation protein inhibitor localization around the site of embolized gastroduodenal artery in a patient with metachronous pancreatic adenocarcinoma: A potential pitfall in positron imaging.

Gallium-Fibroblast activation protein inhibitor (Ga-FAPI) positron emission tomography/computed tomography (PET/CT) is increasingly used for evaluating various epithelial neoplasms. Despite addressing some pitfalls, many remain unacknowledged. This report details a 77-year-old man with suspected pancreatic malignancy who underwent a Ga-FAPI PET/CT scan post-gastroduodenal coil embolization for upper gastrointestinal bleeding.

Retrograde Arterial Flow Secondary to Median Arcuate Ligament Syndrome as a Contraindication to Gastroduodenal Artery Angioembolization.

Median arcuate ligament syndrome (MALS) is a rare condition in which the median arcuate ligament (MAL) exerts external compression on the celiac trunk. Most cases are asymptomatic and diagnosed incidentally on radiographic imaging; however, some patients may experience gastrointestinal (GI) symptoms related to foregut ischemia and/or celiac neuropathy. In the following case, we present a patient with hemorrhagic peptic ulcer disease of the duodenum, which resulted in episodes of hemodynamic instability requiring multiple blood transfusions.

Transcatheter Arterial Embolization for Bleeding From the Proper Hepatic Artery Caused by a Duodenal Ulcer: A Case Report.

Although bleeding is the most common complication of peptic ulcer disease, bleeding from the proper hepatic artery is unusual. We report on the case of an 87-year-old woman who presented with melena. An upper endoscopy was performed for a bleeding duodenal ulcer; however, the bleeding could not be controlled.

A rare differential diagnosis of inflammatory bowel disease in a young male patient; a challenging case report.

Background: Chronic granulomatous disease (CGD) is a rare disorder normally diagnosed in infancy.

Case Presentation: A 27-year-old man admitted with non-specific symptoms of CGD first underwent endoscopy, and colonoscopy procedures as primary evaluation of clinical presentation. Eighteen months after the first admission, he was referred to the emergency department for hematemesis, and critical situations, such as a severe anemic with Hgb= 2.

A Rare Case of Gastroduodenal Artery Aneurysm Rupture with Perforated Duodenal Ulcer.

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.

Perforated Peptic Ulcer: A Case Report of a Dreaded Complication of an Insidious Disease.

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.

Pancreatic Tuberculosis With Duodenal Fistula Presenting as Life-Threatening Gastrointestinal Bleeding.

Pancreatic tuberculosis (TB) warrants heightened suspicion in individuals with pancreatic lesions and risk factors such as HIV, organ transplantation, or pertinent immigration history. We present a 38-year-old man who presented with hemodynamically unstable gastrointestinal bleeding. He was found to have pancreatic TB complicated by a duodenal ulcer with fistula.

Insights into the Structure of Sucralfate by Advanced Solid- and Liquid-State NMR.

Sucralfate, which is a sucrose octasulfate aluminum complex, is an active pharmaceutical ingredient (API) falling in the category of cytoprotective agents which are very effective for gastric and duodenal ulcers. On interaction with stomach acid, it ionizes into aluminum and sucrose octasulfate ions to form a protective layer over the ulcerated region inhibiting further attack from acid. The mechanism of action of sucralfate in the context of its structure is not well understood.

Endoscopic removal of an esophageal foreign body and endoscopic closure of its associated perforation with early mediastinitis.

A 55-year-old male swallowed fish bone accidentally and subsequently developed retrosternal pain. He underwent chest computed tomography at his local hospital on October 23, 2023, showing esophageal foreign body with suspected esophageal rupture. One day later, he underwent endoscopy at our department, showing a fish bone penetrated into the esophageal wall.

Successful endoscopic combined with endovascular haemostasis of a ruptured pseudoaneurysm of the duodenal bulb: A case report.

Pseudoaneurysms are uncommon but their rupture and bleeding can lead to serious complications and be fatal. We present here a case of a man in his late 70s who was transferred to our hospital with persistent gastrointestinal bleeding. One month prior to his admission, he had undergone surgery for a fracture to his left knee.
