Description

Meckel's diverticulum is a congenital abnormality of the gastrointestinal tract. It is a small outpouching or sac that forms in the lower part of the small intestine, called the ileum. Meckel's diverticulum occurs due to incomplete closure of the omphalomesenteric duct, a structure that connects the developing intestine to the umbilical cord during fetal development. Meckel's diverticulum is the most common congenital abnormality of the gastrointestinal tract, occurring in approximately 2% of the general population. It is more common in males and is usually detected in childhood or early adulthood, although it can remain asymptomatic throughout a person's life. While Meckel's diverticulum may not cause any problems, it can lead to various complications in some cases, including: 1. Intestinal Obstruction: The diverticulum can twist or become trapped, leading to blockage of the intestine and causing symptoms such as abdominal pain, cramping, nausea, and vomiting. 2. Diverticulitis: Inflammation or infection can occur in the diverticulum, resulting in symptoms similar to appendicitis, such as abdominal pain, fever, and tenderness. 3. Gastrointestinal Bleeding: Meckel's diverticulum may contain tissue similar to that found in the stomach or small intestine, which can produce acid and cause ulceration. This can result in intermittent bleeding from the rectum, typically in children. 4. Perforation: In rare cases, the diverticulum can rupture or perforate, leading to peritonitis, an infection and inflammation of the abdominal cavity. Diagnosing Meckel's diverticulum can be challenging, as it may not always cause symptoms and can be mistaken for other conditions. However, various imaging tests, such as abdominal ultrasound, computed tomography (CT) scan, or technetium-99m pertechnetate scintigraphy, can help identify the diverticulum. The treatment for Meckel's diverticulum depends on the presence of symptoms and complications. Asymptomatic diverticula usually do not require treatment. However, if complications arise, surgical intervention may be necessary. The most common procedure is called a diverticulectomy, which involves removing the diverticulum. In cases of significant intestinal obstruction, resection of the affected segment of the small intestine may be required. If you suspect you or someone you know may have Meckel's diverticulum or are experiencing symptoms related to it, it is important to seek medical attention for proper evaluation and management. Intussusception Causes of intussusception Intussusception is a medical condition in which a segment of the intestine folds inward and telescopes into an adjacent segment. This telescoping can cause obstruction and blockage of the intestine, leading to severe abdominal pain, vomiting, and sometimes bloody stools. Intussusception most commonly occurs in infants and young children and requires prompt medical attention or surgery to correct the condition. Symptoms of intussusception The symptoms of intussusception can vary depending on the severity and duration of the condition. Common symptoms include: 1. Severe abdominal pain: Intussusception typically causes intense, cramp-like abdominal pain that comes and goes in waves. The pain may be intermittent or persistent. 2. Vomiting: Affected individuals may experience episodes of vomiting, which can be forceful and projectile. 3. Crying and irritability: Infants and young children with intussusception may cry excessively and appear very irritable, especially during episodes of abdominal pain. 4. Bloody stools: Some individuals may pass stools that contain blood or have a reddish appearance. This is known as "currant jelly" stools, which occur due to bleeding into the intestine. 5. Palpable mass: In some cases, a firm mass can be felt in the abdomen. However, this symptom is not always present. 6. Lethargy and weakness: If intussusception leads to intestinal blockage and reduced blood flow, it can cause symptoms of lethargy, weakness, and decreased responsiveness. It is important to note that the presence of these symptoms does not necessarily confirm intussusception, as they can also be associated with other medical conditions. If you or someone you know is experiencing these symptoms, it is crucial to seek immediate medical attention for proper diagnosis and treatment.
