Abdominal causes of clubbing
(4)
- Cirrhosis: esp with PBC
- IBD
- Coeliac
- GI lymphoma
- What are spider naevi?
- Where are they?
- How many = pathological?
- What are you differential diagnosis?
- Central arteriole with radiating vessls (fill fom the centre-telangiectasia fill from the edge!)
- found in the distribution of the SVC
- >4= abnormal
- differential diagnosis: CLD, OCP, Pregnancy
Inguinal hernia
Examination; set up/inspection/palpation/ausc/special/complete
Set up:
- Expose from umbilisu to knees
- begin with pt STANDING!
Inspection:
- look for any masses in groins
- sie, site, features of inflammation (strangulation), ask pt to cough
- look for scars:
- previous hernia op, appendicectomy (risk factor for direct hernia!)
Palpation:
- check if in pain
- palpated mass for cough impulse
- Define anatomy (relationship to PT)
- above (and medial); inguinal hernia
- below (and lateral): femoral hernia
- Does mass extend into scrotum:
- inguinoscrotal hernia; more likely to indirect
auscultate:
- bowel sounds: hernia may lack bowel sounds if only contains fat/omentum
REPEAT INSPECTION AND PALPATION with pt SUPINE!
Direct vs indirect hernia test
complete:
- Examine external genitalia: incidental lumps, testes
- contralateral groin
- examine abdomen
- evidence of increased IAP: masses, ascites
- Other hernias: paraumbilical, umbilical
Test for direct vs indirect hernia
- ask pt to reduce hernia
- place 2 fingers over deep ring (mid pt of inf lig (1.5 cm above fem pulse)) and ask pt to cough
- hernia controlled=indirect
- not controlled= direct
not accurate test: definitive determination in theatre!
Groin lump differential! (10)
- Skin: sebaceous cyst, psoas abscess
- Fat: lipoma
- CT: fibroma
- Nerves: neuroma of femoral nerve
- Lymphatics: LN
- Veins: sphena varix
- Arteries: femoral artery aneurysm
- Inguinal canal: inguinal hernia, hydrocele or lipoma of cord
- femoral canal: femoral hernia
- Testes: undescended testis
4 distinguishing features of an inguinal hernia
- Above and medial to PT
- cough impulse
- Reducible
- bowel sounds
Hx Qs for inguinal hernia
- predisposing factors: cough, straining, lifting
- pain
- reducible
- episodes of obstruction or strangulation
- previous repairs
Management of inguinal hernia
(conservative, surgical)
Conservative:
- Manage RFs e.g. constipation, cough
- weight loss
- elastic corset or truss
Surgical:
- Open: lichtenstein tension free mesh
- lap: TEP or TAPP mesh
TEP= Totally ExtraPeritoneal
TAPP=TransAbdominal PrePeritoneal (TAPP)
Inguinal hernias
definition; general
classification (2 types)
Protrusion of a viscus or part of a viscus into an abnormal position through a defect in its containing cavity
- Indirect: 80%:
- commoner in young due to congenital patent processus vaginalis
- emerge through deep ring
- same 3 coverings as cord
- descents into scrotum
- can strangulate
- Direct: 20%
- commoner in elderly
- aquired: weak posterior wall of canal
- emerges through hasselbach’s triangle
- can acquire internal and external spermatic fascia
- rarely descends into scrotum
- rarely strangulates
Inginal canal antomy
MALT
superior/anterior/lower/posterior
-
superior wall (roof): Muscles
- internal oblique M
- Transferse abdominus M
-
Anterior wall: Aponeuroses
- A of external oblique
- A of internal oblique
-
Lower wall (floor): Ligaments
- Inguinal L
- Lacunar L
-
Posterior wall: Ts
- Transfersalis fascia
- conjoint Tendon
Femoral canal anatomy
med/late/ant/post
and contents
Med: lacunar ligament
Lat: femoral vein
Ant: inguinal ligament
Posterior: pectineal ligament (of cooper)
Contents: fat and cloquet’s node
Contents of inguinal canal (MF!)
M: spermatic cord + ilioinguinal N
F: Round lig + gen branch of genitofemoral N + ilioingional N
Contents of spermatic cord
- 3 layers of fascia
- External spermatic F
- Cremater musle and F
- Internal spermatic F
- 3 arteries + 3 veins
- Testicular A + Pampiniform plexus of testicular V
- Cremateric A and V
- Artery to vas deferens
- 2 nerves:
- genital branch of genitofemoral N
- Autonomic N
- 2 others:
- Vas deferens
- lymph vesels
Intra-operative distinction of indirect and direct inguinal hernia
- indirect: arise lateral to inf. epigastic vessels
-
direct: arise medical to inf. epigastric vessels through hasselbach’s triange: (RI?P)
- Med: Rectus abdominis muscle
- Lat: Inferior epigastric artery
- Inf: poupart’s ligamen (inguinal lig)
Inguinal hernia surgical approaches:
open and lap
open and lap; lap if bilateral/recurrent!
nb mention risk of testicular damage when consenting pt
open:
- open can be done under LA or GA: day case
- RCS recoments the lichtenstein tension free mesh repair
- less recurrence cf to older shouldice repair
IN CHILDREN: simple ligation and division of the patent processus suffices: no mesh req
Lap:
- 2 main techniques:
- Total ExtraPeritoneal
- TransAbdominal Pre-Peritoneal
- Better for bilateral hernias
Complications of surgical inguinal hernia repair
Early/late
management for optimal post-op recovery
- Early:
- Urinary retention
- Haematoma/seroma formation 10%
- Infection
- Intra-abdominal injury (lap!)
- Late:
- recurrence <2%
- ischaemic orchitis 0.5%; 2ndary thrombosis of pampiniform plexus
- chronic groin pain/paraesthesia 5%
- Post op recovery
- pee pre leaving; retention
- avoid constipation: lactulose
- Early mobilisation
- painful; good analgesia
- keep area clean and dry: wash carefully (can bathe immediately)
- work in 1-2wks
- heavy lifting >6wks)
Femoral hernia
general
- Commoner in Females; wider femoral canal
- middle ages and elderly
- neck is inferior and lateral to PT
- high risk of obstruction and strangulation
Femoral hernia
management
elective and emergency
50% risk of strangulation within 1 mnth -> URGENT surgery
-
Elective: lockwood low approach
- low incision over hernia with herniotomy and herniorrhaphy (suture inguinal ligament to pectineal ligament)
-
Emergency: Mc Evedy high approach
- high approach in inguinal region to allow insprection and resection of non-viable bowel
- then herniotomy and herniorrhaphy
Incisional hernia
Examination (inspection, palpation, ausc)
Examination
-
inspection:
- pt may be overweight
- describe scars and drain sites
- any evidence of inflammation
- ask pt to lift head off bed and cough
-
palpation:
- any tenderness?
- feel for presence of detect
- ask pt to cough while feeling for an impulse
- is the defect present along the whole legth of the scar?
- sie of defect relates to risk of strangulation
- If a lump is present, can it be reduced
- auscultate: for bowel sounds
Incisional hernia
Important history questions
- previous surgery
- post op wound infection or other complications
- co-morbidities-> increased risk e.g. chronic cough
- discomfort or episodes of obstruction
Incisional hernia:
definition
Extrusion of peritoneum and abdominal contents through a previously acquired defect
Incisional hernias:
Complications
Intestinal obstruction
irreducible
strangulation
pain/discomfort
Incisional hernia
RF:
PreOp/Intra-op/postOp
-
Pre-Op:
- increase age
- comorbidities: DM, renal failure
- drugs: steroids, chemo, radio
- Obesity or malnutrition
- malignancy
-
Intra-Op:
-
surgical technique/skill (major factor)
- too small suture bites
- inapropriate suture material
- incisional type e.g. midline
- placing drains through wounds
-
surgical technique/skill (major factor)
-
Post-Op:
- increased IAP: chronic cough, straining, post-op ileus
- infection
- Haematoma
