Where is the most common location of an anal fissure?
Posterior midline - consider other diagnisis if off midline, transferse or irregular.
Treatment:
1. avoid trigger
2. lifestyle
- stool bulking agents
- high fiber diet
- periodic use of oral mineral oil (avoid long term use since this reduces the assimulation of fat soluble vitamins
3. Additional treatments after failed diet interventions
- intra anal nitro ointment
- botulinimum toxicum injected in inter and outer spincter

For discomfort:
sitz bath,
hemorrhoids
Description of bleed:
Bright streaks of blood on the stool; anything else should be sent for colonoscopy.
s/sx:
itch, mucus leaking, staining undergarments.
thrombosed external hemorrhoids: very painful; external; will resolve in
Treatment
weight control
topical corticosteroids
astringints
analgesics
sitz bath
use of a stool softner
fiber - 20-30 grams of fiber
surgical interventions
rubber band ligation
surgical removal
Risk factors:
prolonged sitting
receptive anal sex
chronic diarrhea
excessive alcohol use.
Grade 1:
hemorrhoids do not prolapse
Grade 2:
hemorrhoids prolapse with defecation but reduce spontaneously
Grade 3
hemorrhoids prolapst upon defaction and must be reduced manually
Grade IV
hemorrhoids are prolasped and can not be reduced manually
risk factors:
- alchohol use
- chronic diarrhea/constipation
- obestiy
