Abstract:
A Meckel's diverticulum (MD) is an embryonic remnant of the omphalomesenteric duct. Although most MDs are usually asymptomatic, pediatric patients tend to present serious complications more frequently (4-25% of cases), mainly in digestive tract bleeding, intestinal obstruction, and perforation, which have a high potential to compromise the patient's life. An ectopic pancreas (EP) is pancreatic tissue found outside the pancreas, usually in the stomach, duodenum, and jejunum. It is typically asymptomatic but can increase the risk of complications in the MD. A clinical case of a female infant with an MD complicated with bleeding and ileo-ileal intussusception is presented, in which the histopathological finding of type 1 ectopic pancreatic tissue was also found based on the Heinrich classification, being an entity uncommon in our environment. An EP arising within an MD is infrequent, requiring clinical attention and timely preoperative diagnosis to prevent and treat associated severe complications. This continues to be a superior challenge for the clinician and requires a multidisciplinary team for comprehensive treatment.
Insights
Meckel
Area of Science:
- Pediatric Surgery
- Embryology
- Gastroenterology
Background:
- Meckel's diverticulum (MD) is a congenital anomaly, an embryonic remnant of the omphalomesenteric duct.
- While often asymptomatic, MDs can cause severe complications in pediatric patients, including bleeding, obstruction, and perforation.
Observation:
- This report details a case of a female infant presenting with Meckel's diverticulum complicated by gastrointestinal bleeding and ileo-ileal intussusception.
- Histopathological examination revealed Type 1 ectopic pancreatic tissue within the Meckel's diverticulum, classified according to the Heinrich classification.
Findings:
- Ectopic pancreatic tissue within a Meckel's diverticulum is an infrequent occurrence.
- The presence of ectopic pancreas in MD increases the risk of serious complications, necessitating careful clinical evaluation.
Implications:
- Timely preoperative diagnosis of ectopic pancreas in Meckel's diverticulum is crucial for preventing and managing severe pediatric surgical emergencies.
- A multidisciplinary approach is essential for the comprehensive management of these rare but potentially life-threatening conditions.

Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
