anastomosis

A

surgical joining of two ducts, vessels, or bowel segments to allow flow from one to another

ileorectal: surgical connection of ileum and rectum after total colectomy
intestinal: surgical connection of two portions of the intestines; also called enteroenterostomy

Q

vertical banded gastroplasty

A

a type of bariatric surgery in which the upper stomach near the esophagus is stapled vertically to reduce it to a small pouch. A band is then inserted that restricts food consumption and delays its

17
Q

Roux-en-Y gastric bypass

A

Stomach is first stapled to decrease it to a small pouch. Next, the jejunum is shortened and connected to the small stomach pouch, causing the base of the the duodenum leading from the nonfunctioning portion of the stomach to form a Y configuration. This configuration decreases the pathway of food through the intestine, thus reducing absorption of calories and fats

Q

polypectomy

A

excision of a polyp.
When polyps are discovered during sigmoidoscopy or colonoscopy, they are excised for microscopic tissue examination for abnormal or cancerous cells
