Abstract:
Pneumatosis cystoides intestinalis (PCI) is a rare disease that involves the presence of gas in the intestinal wall. Connective tissue disease (CTD) is a major cause of secondary PCI. In addition to the nature of CTDs, the use of prednisolone and some immunosuppressants, and the presence of complicating diseases such as diabetes mellitus, constipation and pulmonary diseases are involved in the development of PCI. This report describes four cases of PCI with different CTDs (granulomatosis with polyangiitis, rheumatoid arthritis, dermatomyositis, and overlap syndrome) and discusses the background of each patient and common risk factors for the occurrence of PCI.

Chronic Bowel Disorders: Introduction
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...

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
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...
