Abdo Flashcards
Anatomy of the inguinal canal
Anterior: external oblique and internal oblique for the lateral third
Posterior: transversalis fascia and conjoint tendon for medial third
Floor: inguinal ligament
Roof: arching fibre of transversus and internal oblique
Contents of inguinal canal
M: spermatic cord and illoinguinal nerve
F: round ligament, illoinguinal nerve , gen branch of gen fem nerve
Hesselbach’s triangle
Medial: rectus abdominis
Lateral: inferior epigastric artery
Inferior: inguinal ligament
Classification of inguinal hernia
Indirect - 80% - patent processus vaginalis - arise lateral to inferior epigastric artery
Direct -20% - emerge through hesselbach’s triangle - due to acquired weak wall of canal
Laparoscopic techniques for inguinal hernia
TEP: totally extra peritoneal
TAPP: transabdominal pre- peritoneal
Complications of inguinal hernia repair
Early - urinary retention - haematoma/ seroma formation - infection - intrabdominal Injury Late - reoccurrence
Borders of the femoral canal
Medial: lacunar ligament
Lateral: femoral vein
Anterior: inguinal ligament
Posterior: pectineal ligament of cooper
Operative management of a femoral hernia
Elective: Lockwood low approach
Emergency: McEvedy high approach
Definition of an inguinal hernia
Extrusion of peritoneum and abdominal contents through a previously acquired defect
Risk factors for incscional hernias
Pre-op: increased age, co-mobrdities ( malignancy and obesity ) Intra - op: surgical technique ( width of suture bites, suture material, midline, placing drain through wounds ) Post op: incensed IAP, infection, heamatoma
Cause of a paraumbilcal hernia
Acquired defect in linea Alba just above or below the umbilicus
Definition of a hernia
Protrusion of a viscus or part of a viscus into an abnormal position through a defect in its containing cavity
Risk factor for umbilical hernias
Afro-Caribbean
Trisomy 21
Congenital hypothyroidism
Definition of a hydroele
Accumulation of fluid within the tunica vaginalis
Tunica vaginalis is a rememant of the processus vaginalis
Cause of hydroceles
Primary: patent processus vaginalis
Secondary: testicular tumours, epidymo-orchitis, trauma, torsion
Surgical treatment of hydrocele
Lords repair: plication of the tunica vaignalisJaboulay’s repair: eversion of the sac
Definition of a varicocele
Dilated viens of the pampinifrom plexus
Operation for varicocele
Palomo operation
Risk factor for testicular cancer
Undescended testis Infant hernia Infertility
Royal marsden classification of testicualr cancer
- Disease only in testis
- Sub diaphragmatic para-aortic node involvement
- Supra and infra diaphragmatic lymph nodes involved
- Extra lymphatic spread - lungs liver
No scars and stoma =
Colonoscopy assisted trephine colostomy
Definition of a stoma
Artificial union between conduits or between a conduit and the outside
Fistula definition
Abnormal connection between two hollow epithelial surface
Indication for a stoma
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
