A
Indirect - 80% 
- patent processus vaginalis 
- arise lateral to inferior epigastric artery

16
Q

Anatomical classification of hydroele

A

Vaginal: accumulation in the tunica vaginalis that does not extend up the cord
Congenital: proximal part of the processus has not obliterated and sac communicates directly with preitoneum
Infantile: processus is obliterated at the deep ring but still extend up the cord
Hydroele of the cord: fluid accumulate around the ductus deferens

17
Q

Cause of hydroceles

A

Primary: patent processus vaginalis
Secondary: testicualr tumours, epidymo-orchitis, trauma, torsion

18
Q

Surgical treatment of hydrocele

A

Lords repair: plication of the tunica vaignalis

Jaboulay’s repair: eversion of the sac

19
Q

Definition of a varicocele

A

Dilated viens of the pampinifrom plexus

20
Q

Operation for varicocele

A

Palomo operation

21
Q

Risk factor for testicualr cancer

A

Undescended testis
Infant hernia
Infertility

22
Q

Royal marsden classification of testicualr cancer

A
  1. Disease only in testis
  2. Sub diaphragmatic para-aortic node involvement
  3. Supra and infra diaphragmatic lymph nodes involved
  4. Extra lymphatic spread - lungs liver
23
Q

No scars and stoma =

A

Colonoscopy assisted trephine colostomy

24
Q

Definition of a stoma

A

Artificial union between conduits or between a conduit and the outside

25
Q

Fistula definition

A

Abnormal connection between two hollow epithelial surface

26
Q

Indication for a stoma

A
Exteriorisation 
- perforated or contaminated bowel 
- permenant 
Diversion
- protection of distal anastomosis
- acute chrons 
- urinary diversion following cystectomy 
Decompression: bypass of distal obstructing lesion 
Feeding: gastrostomy/ jejunostomy 
Laveage: appendecictomy
27
Q

How to site a stoma

A

Avoid: bony prominences, skin folds/creases, waistline, old wounds, umbilicus
Chose
- a site that is easily accessible to the patient
- ideally below the belt line for concealment
- within the rectus: decreased risk of hernia or prolapse

28
Q

Complication of a stoma

A
Early 
- haemorrhage 
- ischemia 
- hight out put leading to electrolyte disturbances 
- parastomal abscess 
- stoma retraction 
Delayed 
- parastomal hernia - more common on the lateral side 
-obstruction: adhesion or herniation through lateral space around stoma 
- dermatitis 
- stoma prolapse 
- stenosis or stricture 
- fistula 
- psychosexual dysfunction
29

Linea Alba 
Transversalis fascia 
Pre-peritoneal fat 
Preitoneum 

Some catholic sluts like to practise phallactio

30
Q

A

Length of suture should be 4 times the length of the incscion

31
Q

Indication for midline stenotomy

A
