Abstract:
We report a case of silent bowel perforation by a fractured subduroperitoneal shunt after surgical shunt revision. A 93-year-old bedridden man experienced transanal prolapse of a shunt catheter after defecation. Upon arrival, the patient showed no fever or acute abdominal signs. Abdominal computed tomography (CT) showed an abandoned shunt catheter in the lower abdomen with rectum perforation. The disconnected catheter was successfully removed from the anus by digital rectal maneuver, and no peritonitis or other complication developed afterward. Such broken shunts no longer provide drainage function, and also pose a risk of migrating into the hollow viscera. Therefore, even in the absence of overt peritoneal signs, disconnected catheters should be removed by laparoscopic or minimal surgery to prevent possible development of this unusual complication. Instances of the rare complication are reviewed, and pathogenesis and treatment of the condition are discussed.

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...
