How should a digital rectal exam be performed?

feel coccyx, then levator ani muscle, feel sacral hollow, prostate in male or tip of cervix in female
always palpate sphincteric mechanism

What is anoscopy?

short scope looks at distal rectum and anal canal
essential for defining hemorrhoids

What is proctoscopy?

inspects rectum up to recto-sigmoid junction
can visualize and biopsy
economical

What is fiber-optic endoscopy?

asses distal colon, or entire colon
= flexoid sigmoidoscopy

What is a barium enema?

gives good outline of bowel
might miss polyps, biopsy and intervention not possible

What is virtual colonoscopy?

reconstruction of colon structure using CT and computer 3D modeling
similar accuracy to colonoscopy but not invasive
but cannot biopsy or intervene

What are the possible complications of diverticulosis?

diverticulitis - neck becomes obstructed and perfs
abscess - drain
peritonitis from perf - surgery!
fistula - most often to bladder - surgery!

What is the clinical presentation of diverticulitis?

LLQ pain, fever, constipation or diarrhea
