Gallbladder01:17

Gallbladder

2.1K
The gallbladder is a small, pear-shaped organ that plays a crucial role in our digestive system. Measuring about 10 cm in length, it is comparable in size to a kiwi fruit and is located in a hollow area on the lower surface of the liver. The gallbladder's primary function is to store and concentrate bile, a fluid produced by the liver that aids in digestion.
The gallbladder's anatomy consists of three regions: the fundus, body, and neck. Extending from the neck, the cystic duct joins...

Diseases of the Liver and Gallbladder

1.9K
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Muscle Contraction

8.8K
In skeletal muscles, acetylcholine is released by nerve terminals at the motor endplate—the point of synaptic communication between motor neurons and muscle fibers. The binding of acetylcholine to its receptors on the sarcolemma allows entry of sodium ions into the cell and triggers an action potential in the muscle cell. Thus, electrical signals from the brain are transmitted to the muscle. Subsequently, the enzyme acetylcholinesterase breaks down acetylcholine to prevent excessive...

Lobes of the Cerebrum01:22

Lobes of the Cerebrum

4.3K
The cerebral cortex, a critical structure of the brain, is intricately divided into two hemispheres, each consisting of four distinct lobes: occipital, temporal, frontal, and parietal. These lobes function cooperatively to regulate various cognitive and sensory functions, forming the basis of our complex neural capabilities.
Frontal lobe
The frontal lobes, located behind the forehead, are the command center of our brain, controlling personality, intelligence, and voluntary muscle movements....

Smooth Muscle Contraction01:25

Smooth Muscle Contraction

7.5K
Smooth muscle contraction is a complex process vital for various bodily functions, from maintaining blood vessel tension to facilitating the movement of food through the digestive tract. Unlike striated muscles, smooth muscle contraction begins more slowly and lasts longer.
The onset of contraction is triggered by an increase in calcium ions within the sarcoplasm, similar to the process in striated muscle. However, smooth muscles have a relatively smaller reservoir of the sarcoplasmic...

Area of Science:

  • Hepatobiliary Surgery
  • Transplant Surgery
  • Surgical Innovation

Background:

  • Donor gallbladder removal is standard practice in pediatric liver transplantation.
  • Preserving the donor gallbladder may offer benefits but requires functional assessment.

Purpose of the Study:

  • To assess the feasibility and impact of donor gallbladder preservation in liver transplantation.
  • To evaluate the recovery of gallbladder contraction function after preservation during living donor hepatectomy.

Main Methods:

  • Ultrasound measurements of gallbladder volume and ejection fraction (EF) in 42 donors before and after surgery.
  • Evaluation of gallbladder contraction function changes over time post-preservation.

Main Results:

  • Gallbladder emptying index decreased to 42.67% at 2 weeks post-surgery, recovering to 69.14% by 3 months.
  • 97.6% of donors showed recovered gallbladder contraction function within 1 month.
  • Early post-operative function was not significantly improved, but normalized by 1 month.

Conclusions:

  • Donor gallbladder preservation is a feasible option in liver transplantation.
  • Gallbladder contraction function can be effectively maintained after preservation during living donor hepatectomy.
  • Preservation ensures normal gallbladder function post-recovery.
