Rectal: bleeding, obstruction, alternating diarrhea and constipation
Preop colon cancer eval
Colonoscopy
Maybe CT
CEA blood test

X-ray: bent inner tube sign
CT best test

After an episode of complicated diverticulitis and/or recurrent uncomplicated diverticulitis
Sx of diverticulitis
Change in BM Anorexia Nausea Fever/chills Urinary urgency
Labs for diverticulitis
Will see leukocytosis
Imaging for diverticulitis
CT scan abdomen
Barium enema
Don’t do colonoscopy while inflamed
What STI is a risk factor for colon cancer?
Anal HPV
Colonoscopy screening for high-risk pts
HNCPP FAP Gardners UC and Chron's Screen in teens IBD: Annually after 10 yrs of dx -Consider prophylactic colectomy for high risk pt
Colonoscopy screening recommendation for intermediate risk
Personal hx or strong family hx
Colonscopy at 40 and then q3-5 yrs
Colonscopy screening recommendation for mild risk
Age, diet, physical activity, obesity, smoking, no family hx
Beginning at age 50 have colonscopy q 10 yrs, or yearly fecal occult blood test or flexible sigmoidoscopy q5 yrs

-Rebound tenderness, guarding, decreased bowel sounds, +/- fever
Rovsing’s sign: Deep palpation in LLQ causes rebound referred pain in RLQ
Psoas: RLQ pain which right hip is flexed
Obturator: pain in RLQ when flexed right thigh is internally rotated when pt is supine
Labs/rads of appendicitis

CT scan w/o contrast
U/S
GI sx of hemorrhoids
Nausea
Vomiting
Abdominal pain
Irregular/discolored/bloody stools
Labs for hemorrhoids
Hemoccult
CBC (signs of infection or anemia d/t bleeding)
Coags to check for coagulopathy
Imaging for hemorrhoids
Colonscopy
Anoscopy (anal speculum- mandatory for viewing internal hemorrhoids)
Flexible sigmoidoscopy (to evaluate for proximal dz such as rectal prolapse)
Enteroscopy
Indications for hemorrhoid surgery
Conservative or nonsurgical tx fails
Presence of concomitant anorectal conditions
Pt preference
Grade III or IV hemorrhoids with severe sx
Hx of groin hernia
Pt presents with pain and swelling in groin
