Complications of photodynamic therapy in gastrointestinal disease

Abstract:
The primary complications of photodynamic therapy of the esophagus include cutaneous photosensitivity and esophageal strictures. Atrial fibrillation and pleural effusion have been reported but appear to be rare or not clinically significant. Cutaneous photosensitivity can be minimized if the adequate precautions are taken to protect patients from sunlight exposure. Stricture formation may be decreased by proper dosimetry and avoiding multiple overlapping light applications.

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.
Peptic ulcers can also be...
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...
