Abstract:
Pouchitis is the most common complication following ileal pouch-anal anastomosis. It is characterized by pouch inflammation and symptoms resembling ulcerative colitis. The aetiology is thought to involve a combination of genetic factors, a dysregulated immune response, and alterations in the gut microbiome. Pouchitis is classified as acute if symptoms less-than 4 weeks or chronic if symptoms > 4 weeks. Acute pouchitis is typically treated with antibiotics, while chronic pouchitis may require cyclic antibiotics or immunomodulatory therapy. This review indicates that more research is needed to improve understanding and treatment.

Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...
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.

Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
