Pathogenesis
Various theories are :
1. Portal hypertension and varicose veins
2. Upright posture of human beings
3. Hyperplasia of corpus cavernosum recti
4. Erosion and weakening of wall of veins due to infection secondary to trauma
5. Hard faecal matter obstructing venous return
6. Raised anal canal resting pressure

Congest during Valsalva manoeuvre or increased intra-abdominal pressure.
Increase in the size is the starting point of haemorrhoids.

![Page 45: Hemorrhoids-](https://reader037.vdocument.in/reader037/viewer/2022102418/556173b9d8b42a72118b4b3a/html5/thumbnails/45.jpg)
Sclerotherapy(Mitchell)
Injected in submucosa around pedicle
For Gr I to II haemorrhoids. phenol, vegetable oil,
quinine, and urea hydrochloride.
Albright solution: 5% phenol
in almond or arachis oil with 140 mg of menthol to make 30 ml
![Page 46: Hemorrhoids-](https://reader037.vdocument.in/reader037/viewer/2022102418/556173b9d8b42a72118b4b3a/html5/thumbnails/46.jpg)
Sclerotherapy
Injected in submucosa around pedicle
Causes oedema, inflammatory reaction & intravascular thrombosis.
Submucosal fibrosis & scarring minimises the extent of
mucosal prolapse and potentially shrinks the
haemorrhoid as well.
![Page 47: Hemorrhoids-](https://reader037.vdocument.in/reader037/viewer/2022102418/556173b9d8b42a72118b4b3a/html5/thumbnails/47.jpg)
Sclerotherapy
Injected in submucosa around pedicle
Quick painless Follow up after 6 weeks 2-3 further injections may
be required Free from major
complications

cryosurgery
Freezing of hemorrhoidal tissue liquid Nitrogen probe at -160oC for 3 minutes
Applied for 10-15 minutes Over upper part of hemorrhoidal area
Profuse watery discharge is most common complication (in first 3 hrs)
![Page 53: Hemorrhoids-](https://reader037.vdocument.in/reader037/viewer/2022102418/556173b9d8b42a72118b4b3a/html5/thumbnails/53.jpg)
Cryosurgery
Painless
Causes necrosis of hemorrhoidal tissue
Healing completes in 4-6 wks
Little efficacy in prolapsed hemorrhoids
![Page 54: Hemorrhoids-](https://reader037.vdocument.in/reader037/viewer/2022102418/556173b9d8b42a72118b4b3a/html5/thumbnails/54.jpg)
Infrared photocoagulation
High intensity infra red light 3-6 pulses of 1.5 sec each appllied to mucosa
![Page 55: Hemorrhoids-](https://reader037.vdocument.in/reader037/viewer/2022102418/556173b9d8b42a72118b4b3a/html5/thumbnails/55.jpg)
