Campylobacter concisus was previously shown to be associated with inflammatory bowel disease including Crohn's disease (CD) and ulcerative colitis (UC). C. concisus has two genomospecies (GS). This study systematically examined the colonization of GS1 and GS2 C. concisus in the human gastrointestinal tract. GS1 and GS2 specific polymorphisms in 23S rRNA gene were identified by comparison of the...

Malakoplakie is a chronic granulomatous inflammatory disease, which usually affects the genitourinary tract and less frequently other sites such as, kidney, ureter, bladder, bone, lung, skin, gastrointestinal ovary.

Systemic sclerosis is a connective tissue disease characterized by inflammation and fibrosis of multiple organs (skin, gastrointestinal tract, lung, kidney and heart). After the skin, the organ most affected with a frequency of 75 to 90%, the gastrointestinal tract is more often involved. Gastrointestinal tract involvement is manifested by the appearance of oropharyngeal dysphagia, esophageal d...

As the function of the gastrointestinal tract is to a large degree mechanical, it has become increasingly popular to acquire distensibility data in motility research based on various parameters. Hence it is important to know on which geometrical and mechanical assumptions the various parameters are based. Currently, compliance and tone derived from pressure-volume curves are by far the most oft...

Sonographic scanning techniques of the gastrointestinal tract are presented. Normal anatomy and ultrasound appearance of the stomach, small intestine, and large intestine are discussed, followed by the ultrasound appearance of gastrointestinal inflammation, neoplastic disease, and obstruction.

Various strategies can be used in the diagnosis of upper gastrointestinal tract bleeding. This study investigates the relevance of anamnestic and clinical findings for the diagnosis of the bleeding source. The authors introduced a computer-aided diagnostic system using Bayes’ theorem and compared it with clinicians’ predictions using anamnestic and clinical findings only. There was no differenc...

The authors presented a case of rectovaginal fistula in a 40-year old female patient after gastrointestinal tract continuity restoration (Hartmann's operation) performed because of iatrogenic rectal damage. The most likely cause of rectovaginal fistula development was the erroneous introduction of the stapler into the vagina and sigmoidovaginostomy during an attempt to reconstruct the continuit...
