Summary
A rare congenital condition, retroarterial colon, occurred in a child with trisomy 13. This led to a transmesenteric internal hernia, causing obstructive gangrenous colitis.
Area of Science:
- Gastroenterology
- Pediatric Surgery
- Medical Genetics
Background:
- Retroarterial colon is a rare anatomical anomaly where the colon lies posterior to the superior mesenteric vessels.
- Transmesenteric internal hernias involve bowel protrusion through mesenteric defects, often acquired but can be congenital.
Observation:
- A 10-year-old female with trisomy 13 presented with intestinal malrotation, specifically lacking retroperitoneal fixation.
- The patient exhibited a retroarterial transverse colon, suggesting a congenital origin.
Findings:
- The anatomical anomaly was consistent with a possible congenital transmesenteric internal hernia.
- This condition ultimately resulted in obstructive gangrenous colitis.
Implications:
- This case highlights the potential link between trisomy 13, intestinal malrotation, and congenital internal hernias.
- Understanding these rare presentations is crucial for diagnosing and managing pediatric gastrointestinal emergencies.

01:21Inflammatory Bowel Disease V: Surgical Management
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

01:19Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
01:27Diverticular Disease of the Colon
Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...
01:26Inflammatory Bowel Disease I: Introduction
Inflammatory bowel disease is a group of chronic disorders marked by recurrent inflammation of the gastrointestinal tract due to an abnormal immune response against gut microflora. This leads to tissue damage. The two main forms are Crohn’s disease and ulcerative colitis.Crohn’s DiseaseCrohn’s disease is a relapsing inflammatory disorder that can affect any part of the GI tract, from the mouth to the anus. It involves all layers of the bowel wall (transmural) and shows “skip lesions” in which...
01:29Appendicitis-II: Diagnostic Studies and Management
Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...
