Abstract:
A man in his late 60s with prior Hartman's procedure underwent colostomy takedown and complex ventral hernia repair. He subsequently developed gastrointestinal (GI) bleeding from a duodenal bulb ulcer. Despite five endoscopic procedures aimed at achieving haemostasis, including placement of an over-the-scope clip, and four endovascular embolisations (inferior and superior pancreaticoduodenal, right gastroepiploic and gastroduodenal arteries), the patient continued to experience episodic, haemodynamically significant bleeding. He eventually required emergency exploratory laparotomy, where the proper hepatic artery was identified as the source (a previously unreported phenomenon). He underwent antrectomy and proper hepatic artery ligation. This case highlights the need to interrogate all portions of the hepatic vasculature in the treatment of refractory GI bleeding.

Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
Peptic Ulcer Disease II: Pathophysiology
Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.
Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
