Stands for percutaneous endoscopic gastrostomy, a surgical procedure for placing a feeding tube without having to perform an open laparotomy (operation on the abdomen). The aim of PEG is to feed those who cannot swallow. PEG may be done by a surgeon, otolaryngologist (ENT specialist) or gastroenterologist (GI specialist). It is done in a. hospital or outpatient surgical facility. Local anesthesia (usually lidocaine or another spray) is used to anesthetize the throat. An endoscope (a flexible, lighted instrument) is passed through the mouth, throat and esophagus to the stomach. The surgeon then makes a small incision (cut) in the skin of the abdomen and pushes an intravenous cannula (an IV tube) through the skin into the stomach and sutures (ties) it in place. The patient can usually go home the same day or the next morning. Possible complications include wound infection and dislodging or malfunction of the tube. PEG takes less time, carries less risk and costs less than a classic surgical gastrostomy which requires opening the abdomen.

Pediatric End-Stage Liver Disease. A disease severity scoring system for children under 18 years of age, designed to improve the organ allocation in transplantation based on the severity of liver disease rather than time on the waiting list. The PELD score is based on both laboratory data and growth data. The laboratory values are a […]
- Peliosis hepatis
A rare condition in which the liver contains multiple, randomly-distributed blood-filled spaces or cavities ranging in size from millimeters to several centimeters in diameter. Peliosis hepatis has been associated with the use of anabolic steroids and other hormones such as oral contraceptive pills. It has also been observed in association with both benign and malignant […]
- Pelizaeus-Merzbacher disease
A disorder of the central nervous system (CNS) in which there is loss of myelin, the sheath around the nerves. The disease is clinically characterized by nystagmus (rhythmical oscillation of the eyes), impaired motor development, tremor, progressive spasticity (increased muscle tone), ataxia (wobbliness), choreoathetotic movements, and dysartria (difficulty speaking). Pelizaeus-Merzbacher disease (PMD) in its classical […]
- Pelizaeus-Merzbacher-like disease
A disease that is virtually identical to Pelizaeus-Merzbacher disease (PMD) but without a mutation in the PLP1 gene that causes PMD. Both PMD and Pelizaeus-Merzbacher-like disease (PMLD) are characterized by rapid, involuntary movements of the eye (nystagmus), impaired motor development, ataxia, and difficulty articulating. Some patients with PMLD have diverse mutations in a gene called […]
