    Insights

    An inverted Meckel's diverticulum caused rare ileo-ileal intussusception and lower gastrointestinal bleeding in an adult. This case highlights the importance of considering this condition in patients presenting with acute abdomen and bleeding.

    Area of Science:

    • Gastroenterology and Surgical Case Reports
    • Abdominal Surgery
    • Pediatric Surgery

    Background:

    • Meckel's diverticulum is a congenital anomaly of the small intestine.
    • Intussusception is the telescoping of one segment of the intestine into another.
    • Inverted Meckel's diverticulum is a rare cause of intussusception, particularly in adults.

    Observation:

    • A 28-year-old male presented with symptoms of incomplete small bowel obstruction, abdominal pain, and significant lower gastrointestinal bleeding.
    • Pre-operative ultrasonography revealed a target-like mass indicative of intussusception with an intraluminal polypoid lesion.
    • Urgent laparotomy confirmed ileo-ileal intussusception.

    Findings:

    • The surgical specimen revealed an 8 cm inverted Meckel's diverticulum within the ileal lumen, causing the intussusception.
    • Histopathological examination confirmed the diagnosis of an inverted Meckel's diverticulum.
    • A 70 cm segment of the small intestine was resected due to the intussusception.

    Implications:

    • This case underscores the importance of considering inverted Meckel's diverticulum in the differential diagnosis of intussusception and gastrointestinal bleeding in adults.
    • Early diagnosis and surgical intervention are crucial for managing complications associated with this rare condition.
    • Further research into the diagnostic and therapeutic strategies for inverted Meckel's diverticulum is warranted.

    Inverting and Non-inverting OpAmps

    In an inverting amplifier, the input voltage is connected through a resistor to the inverting terminal. Meanwhile, the non-inverting terminal is grounded and a feedback resistor is established between the inverting and output terminal, as depicted in Figure 1.

    Bleeding in Fresh Concrete01:22

    Bleeding in Fresh Concrete

    Bleeding in fresh concrete occurs when water from the mix rises to the surface. This happens because the mix's solid components fail to retain all the water as they settle, leading to separation where water collects at the top. The severity of bleeding can be measured by assessing the total settlement or by noting the decrease in height per unit height of concrete.
    Bleeding can cause several issues in the concrete structure. Sometimes, the rising water gets trapped beneath large aggregate...

    Anatomy of the Gastrointestinal System

    The human digestive system is an intricate and essential network for nutrient absorption and waste elimination. It encompasses the gastrointestinal (GI) tract and several accessory organs.

    Gastrointestinal Motility Disorders

    Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...

    Histology of the Gastrointestinal (GI) Tract

    The GI tract, from beginning to end, is made up of four continuous tissue layers that adjust their structure according to their specific roles. These layers, from innermost to outermost, are known as the mucosa, submucosa, muscularis, and serosa, which are continuous with the mesentery.
    The mucosa is sometimes called a mucous membrane due to its mucus-secreting features. This membrane is composed of epithelium, which directly interacts with ingested substances, and the lamina propria, a layer...
