dark, tarlike feces that contain digested blood from bleeding in the esophagus or stomach
obesity
excessive accumulation of fat that exceeds the body’s skeletal and physical standards
morbid obesity
obesity in which body mass index is greater than 40 (about 100 lb over ideal body weight)

(also called lower GI series or barium enema)

magnetic resonance cholangiopancreatography (MRCP)
special MRI technique that produces images of the liver, gallbladder, pancreas, and all the surrounding ducts
abdominal ultrasound
ultrasound visualization of the abdomen
endoscopic ultrasound
combination of endoscopy and ultrasound that examines the digestive tracts and surrounding tissues and organs
upper gastrointestinal series (UGIS)
(also called barium swallow)
radiographic images of the upper GI tracts after giving the patient barium
ileorectal anastomosis
surgical connection of the ileum and rectum
intestinal anastomosis
surgical connection of two portions of the intestines
appendectomy
excision of the appendix
open appendectomy

laparoscopic appendectomy
minimally invasive appendectomy using three small abdominal incisions
bariatric surgery
surgery that reduces stomach size to treat morbid obesity
vertical banded gastroplasty
bariatric surgery that involves vertical stapling of the upper stomach near the esophagus to reduce its size
roux-en-Y gastric bypass (RGB)
(also called gastric bypass with gastroenterostomy)
bariatric surgery that involves stapling the stomach to reduce its size and shortening the jejunum to decrease the pathway of food through the intestine, which reduces the absorption of calories and fats
colostomy
forming an opening in the colon
lithotripsy
crushing a stone
extracorporeal shockwave lithotripsy (ESWL)
use of shock waves to break up stones in the gallbladder or biliary ducts
paracentesis
also called abdominocentesis

antacids
medicine that treats acid reflux and prevents heartburn

medicine that relieves diarrhea
antiemetics
medicine that stops vomiting and controls nausea
