Abstract:
Shiga toxin-producing Escherichia coli (E. coli) is known to be one of the main causes of hemolytic uremic syndrome (HUS). Of the secondary complications of HUS, colonic stricture is relatively rare. We herein report on a Japanese girl that demonstrated sigmoid colon stricture secondary to HUS caused by an infection of E. coli O-157. Severe HUS occurred after the E. coli O-157 infection, so hemodialysis was performed due to renal failure. However, 1 month after recovery from HUS, abdominal symptoms occurred. A contrast study in the colon revealed a sigmoid colon stricture. The stricture was operatively resected. Thereafter, her postoperative course was uneventful. We also review the occurrence of this complication secondary to HUS in the literature.

Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

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...
