Summary
This study reports a rare case of ulcerative colitis (UC) causing severe bronchial stenosis. Treatment with yttrium aluminum garnet (YAG) laser successfully resolved the airway obstruction.
Area of Science:
- Gastroenterology
- Pulmonology
- Oncology
Background:
- Ulcerative colitis (UC) is a chronic inflammatory bowel disease.
- Extraintestinal manifestations of UC are common, but airway involvement is rare.
- Bronchopulmonary lesions are an unusual complication of UC.
Purpose of the Study:
- To report a unique case of ulcerative colitis complicated by severe bronchial stenosis.
- To describe the successful treatment of bronchial stenosis using yttrium aluminum garnet (YAG) laser.
- To highlight the possibility of respiratory involvement in UC.
Main Methods:
- A 37-year-old female patient with a 20-year history of UC presented with respiratory symptoms.
- Diagnostic workup included chest computed tomography (CT) and bronchial biopsy.
- Treatment involved endoscopic intervention with YAG laser therapy.
Main Results:
- Chest CT revealed severe left main bronchus stenosis and left lower lobe bronchiectasis.
- Biopsy confirmed chronic inflammation and lymphocyte infiltration, consistent with UC involvement.
- YAG laser treatment successfully relieved the bronchial stenosis.
Conclusions:
- Respiratory involvement, including bronchial stenosis, can occur as an extraintestinal manifestation of ulcerative colitis.
- YAG laser therapy is an effective treatment for managing bronchial stenosis in UC patients.
- This case represents the first reported instance of UC-associated bronchopulmonary lesions successfully treated with YAG laser.

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...

Introduction
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...

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.

Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal...

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
