The Seldinger technique is used for angiography, insertion of chest drains and central venous catheters, insertion of PEG tubes using the push technique, insertion of the leads for an artificial pacemaker or implantable cardioverter-defibrillator, and numerous other interventional medical procedures.
The PEG procedure is an alternative to open surgical gastrostomy insertion, and does not require a general anesthetic; mild sedation is typically used. PEG tubes may also be extended into the small intestine by passing a jejunal extension tube (PEG-J tube) through the PEG tube and into the jejunum via the pylorus. [1]
A gastric feeding tube (G-tube or "button") is a tube inserted through a small incision in the abdomen into the stomach and is used for long-term enteral nutrition. One type is the percutaneous endoscopic gastrostomy (PEG) tube which is placed endoscopically. The position of the endoscope can be visualized on the outside of the person's abdomen ...
The Stamm gastrostomy is an open technique, [4] requiring an upper midline laparotomy and gastrotomy, with the catheter brought out in the left hypochondrium. It was first devised in 1894 by the American Gastric Surgeon, Martin Stamm (1847–1918), who was educated greatly in surgery when he visited Germany.
The shunt is completed by placing a special mesh tube known as a stent or endograft to maintain the tract between the higher-pressure portal vein and the lower-pressure hepatic vein. After the procedure, fluoroscopic images are made to show placement. Pressure in the portal vein and inferior vena cava are often measured. [citation needed]
This fine bore tube is appropriate for longer use (up to 4 weeks). Types of nasogastric tubes include: Levin catheter, which is a single lumen, small bore NG tube. It is more appropriate for administration of medication or nutrition. [5] This type of catheter tends to be more prone to suctioning against the stomach lining, which can cause ...
[citation needed] A systematic review of clinical trials concluded that a previous history of PEP or pancreatitis significantly increases the risk for PEP to 17.8% and to 5.5% respectively. [20] [21] Intestinal perforation is a risk of any gastroenterologic endoscopic procedure, and is an additional risk if a sphincterotomy is performed.
To further diagnose a pancreatic pseudocyst an abdominal CT scan, MRI or ultrasound can be used. [5] Emergency surgery may need to be performed if there is a rupture of the pseudocyst. This can be detected from symptoms of bleeding, shock, fainting, fever and chills, rapid heartbeat, or severe abdominal pain.
