Sedation (to reduce irritability and agitation of the subject during procedure) with analgesia (painkillers) and vital signs monitoring should be set up. Before the procedure, bedside ultrasound is done to confirm the position of the dilated bile ducts in the liver. The puncture site is then marked.
Abdominal ultrasound can be used to diagnose abnormalities in various internal organs, such as the kidneys, [1] liver, gallbladder, pancreas, spleen and abdominal aorta.If Doppler ultrasonography is added, the blood flow inside blood vessels can be evaluated as well (for example, to look for renal artery stenosis).
Benign liver tumors generally develop on normal or fatty liver, are single or multiple (generally paucilocular), have distinct delineation, with increased echogenity (hemangiomas, benign focal nodular hyperplasia) or absent, with posterior acoustic enhancement effect (cysts), have distinct delineation (hydatid cyst), lack of vascularization or show a characteristic circulatory pattern ...
Choledochoduodenostomy (CDD) is a surgical procedure to create an anastomosis, a surgical connection, between the common bile duct (CBD) and an alternative portion of the duodenum. [1] In healthy individuals, the CBD meets the pancreatic duct at the ampulla of Vater , which drains via the major duodenal papilla to the second part of duodenum. [ 2 ]
In certain cases surgery may include a liver transplantation. [3] Even when surgery is successful the 5-year survival is typically less than 50%. [6] Cholangiocarcinoma is rare in the Western world, with estimates of it occurring in 0.5–2 people per 100,000 per year. [1] [6] Rates are higher in Southeast Asia where liver flukes are common. [5]
Abdominal ultrasonography of the liver, as a sagittal plane through the midclavicular line, with some standard measurements [2] Right lobe of the liver at the midclavicular line at ages 0 to 7 [16] Suspicion of hepatomegaly indicates a thorough medical history and physical examination, wherein the latter typically includes an increased liver span.
Most image-guided surgical procedures are minimally invasive. A field of medicine that pioneered and specializes in minimally invasive image-guided surgery is interventional radiology. A hand-held surgical probe is an essential component of any image-guided surgery system as it provides the surgeon with a map of the designated area. [8]
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
