Insights
Short bowel syndrome (SBS) can cause intestinal failure (IF) in children. In a patient treated with the Serial Transverse Enteroplasty (STEP) procedure for SBS, staple line ulcers were found to be the cause of gastrointestinal bleeding.
Area of Science:
- Pediatric surgery
- Gastroenterology
- Surgical innovation
Background:
- Intestinal failure (IF) is a critical reduction in functional intestinal mass, often necessitating total parenteral nutrition (TPN).
- Short bowel syndrome (SBS) is the leading cause of IF in pediatric patients.
- Small bowel adaptation post-resection involves elongation and dilation, which can lead to dysmotility and bacterial overgrowth, complicating feeding tolerance.
Observation:
- Bowel lengthening procedures like Serial Transverse Enteroplasty (STEP) are indicated for significant small bowel dilation and inability to advance enteral feeds.
- A case is presented of a pediatric patient with IF and SBS secondary to gastroschisis.
- The patient developed anemia and occult gastrointestinal bleeding after undergoing the STEP procedure.
Findings:
- Video capsule endoscopy (VCE) identified multiple ulcerations at surgical staple sites in the distal small intestine.
- These staple line ulcerations were identified as the probable source of intestinal blood loss.
Implications:
- This case highlights a potential complication of the STEP procedure, specifically staple line ulceration leading to bleeding.
- It underscores the importance of VCE in diagnosing obscure gastrointestinal bleeding in pediatric SBS patients post-intervention.
- Further research into optimizing surgical techniques and post-operative monitoring for STEP procedures may be warranted to mitigate bleeding risks.
Abstract:
Intestinal failure (IF) results from a critical reduction in the functional intestinal mass resulting in dependence on total parenteral nutrition (TPN) for growth and survival. Short bowel syndrome (SBS) is the most common cause of intestinal failure in pediatrics. Following resection, the small bowel undergoes adaptation, a process wherein the bowel elongates and dilates in order to increase intestinal absorptive capacity. Small bowel dilatation can lead to dysmotility and small bowel bacterial overgrowth which may further enhance feeding intolerance. Bowel lengthening procedures are beneficial when there is significant dilatation of the small bowel and subsequent inability to advance enteral feeds. We describe a patient with intestine failure and short bowel syndrome due to gastroschisis who, presented with anemia and occult gastrointestinal bleeding, following Serial Transverse Enteroplasty procedure (STEP). Video capsule endoscopy (VCE) revealed multiple ulcerations at surgical staple sites throughout the distal 2/3 of the remaining small intestine which were the likely source of intestinal blood loss.

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...

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
