Protusion of rectum through anus. 3 kinds;
Complete -> >5cm, 2 layers of rectal wall, old age females with weak pelvic floors
Incomplete [Mucosal] -> limited to mucosa in children CF -> straining etc
Concealed -> intussuception of upper into lower rectum

Look at this nice picture
Protrusion of viscus outside normal body cavity
Revision of inguinal anatomy:
Iguinal canal = oblique passage in lower badominal wall through which spermatic cord passes [round ligaminet in fems]
indirect = patent prcessus vaginalis
internal [deep ring] - opening in transversalis fascia 1cm above mid-inguinal point [ASIS -> Pubic symphysis]
Superficial ring -> end -point of canal 1cm medial + superior to pubic tubercle
Describe an indirect inguinal hernia?
- Patent processus vaginalis
- contents enter inguinal ring and into scrotum
-> hydrocele, inguinal hernia, scrotal hernia
- Incarcerated = non-reducible ^^risk of strangulated [nb venous occlusion = first]
Describe a direct inguinal hernia?
- Weakness of abdominal wall
- Precipitated by ^^IA pressure -> lifting
- protrusion through transversalis fascia
- wide neck -> not much worry about incarceration/strangulation
Describe a femoral hernia

What are the types of colon adenoma and where are they found? [Polyps]
75% within rectum + sigmoid colon
Tubular adenoma -> pedunculated/ sessile, retain tubular form similar to gastric mucosa, least likely to transform
Villous adenoma -> sessile [no stalk] + frond like, secrete mucuous, more dysplastic ^^risk of change
Tubulo-villous -> most common, pedunculated stalk = normal mucosa [effect of pullng of jobbies creates stalk

Transverse colon -> transverse colectomy -> middle colic artery
Descending colon -> left hemicolectomy -> left colic artery [branch of inf mesenteric]
Outline resection of rectal/Sigmoid tumour
Sigmoid = sigmoid colectomy -> left lower colic + sigmmoid arteries
For rectum -> resection of superior rectal artery + mesorectum [fat + LN] -> preferably anus sparing
- Ant resection -> 1-2cm from anus
- J-Pouch -> same as AR, but pouch reduces urgency
- APR -> sphincter invasion, proximal colostomy
- Hartmanns -> emergency resection of rectosigmoid lesions, anastamosis at later date
Give 3 CF of bowel obstruction
- Vomiting with relief

How do you discrn between small and large bowel obstruction?
- Small = vomit earlier, less distension, pain higher
- Large -> Pain = constant
- Small = central gas shadows, valvulae conniventaes completely cross lumen
- Large = gas proximal to blockage, not in rectum, Haustra = incomplete
Give 3 causes for obstruction?
