Gallbladder Surgery
The gallbladder is a pear-shaped organ, connected with the common hepatic duct arising from the liver. The gallbladder stores and concentrates bile which is produced by the liver and helps in digestion of fats and certain waste products by releasing the bile into the common hepatic duct. Bile is a yellow-green liquid, composed of water, lecithin, cholesterol, bile salts, and bilirubin.
Occasionally stones may develop in the gallbladder or duct due to improper ratio in the bile of cholesterol, bile salts, or bilirubin that result in blockage of the normal flow of the bile. This presents as severe pain in the upper abdomen. Furthermore, stone formation may produce gallbladder inflammation, a condition known as cholecystitis. Inflammation of the gallbladder without the presence of stone formation is called a calculous cholecystitis, and is often caused from prolonged fasting, severe illness, and several other reasons. In rare cases, gallstone formation may result in cancer development in the gallbladder and biliary ducts.
Symptoms
Gallstones may not cause any symptoms but when symptoms appear, they usually are sudden and often referred to as a “gall bladder attack”. Typical symptoms include:
- Severe abdominal pain
- Back pain near shoulder blades
- Nausea and vomiting
- Abdominal bloating and belching
- Intestinal colic
- Stomach upset
Diagnosis
Gallstones and cholecystitis (inflammation of the gall bladder) can be easily diagnosed through ultrasound. Other advanced techniques or tests include endoscopic ultrasonography, cholescintigraphy (HIDA) scan, CT scan.
Treatment
Gallbladder surgery is considered the best option for gallstone treatment. Most people can live a normal life without their gallbladder, as gallbladder removal results in direct passing of the bile from the liver into the small intestines through ducts.
The surgery to remove the gallbladder is called a cholecystectomy and is, usually performed through laparoscopic techniques which are minimally invasive as compared to open abdominal surgery which requires a long incision. In laparoscopic gallbladder surgery, small incisions are made to insert surgical instruments, along with a laparoscope that has a light source with a camera on the end. The laparoscope helps to locate the gallbladder and tiny instruments are used to surgically remove it.
Gallbladder surgery may require an overnight stay in the hospital. The major complication of gallbladder surgery is injury to the bile ducts that can result in leakage of the bile inside the body and may cause pain and infection.
In cases where gallstones are present inside the bile ducts, endoscopic retrograde cholangiopancreatography (ERCP) technique can be used during gallbladder surgery. ERCP technique involves swallowing a long, flexible tube, with a light source, called an endoscope that is connected with a viewing monitor. The endoscope reaches the small intestine through the stomach and the affected duct is located by releasing a special dye. The affected duct can be cut with tiny instruments located on the endoscope, followed by capturing of the gallstones in a mesh basket that is then removed along with the endoscope.
