Clinical features of strangulated hernia:

◼️Sudden pain starting at the hernial site followed by generalized abdominal pain, this pain is colicky in nature and mainly around the umbilicus.
◼️Nausea and vomitting.
◼️ Recent increase in the size of the hernia.
◼️Extreme tenderness over the hernia.
◼️Tense hernial sac.
◼️Irreducible hernia.
◼️Absence of expansile cough impulse.

N.B sudden spontaneous cessation of pain must be viewed with caution as this may be a sign of perforation

Pathology Of Strangulated Hernia

◼️Constriction ring develops and impairs blood supply (thin black arrow)

◼️Venous return from the involved segment is affected first.

◼️Congestion develops with transudation of serous fluid into the hernial sac.

◼️Distension of the involved loop and edema results in furthur narrowing of the ring and compromising blood supply even more.

◼️Arterial supply then becomes more and more compromised.

◼️The viability of the bowel becomes affected resulting in translocation of bacteria through the wall leading to infection of the sac.

◼️If left unrelieved, gangrene develops (usually within 6 hours) first at the seat of constriction ring (thick black arrow) then at the antemesentric border(yellow arrow) perforation is expected in these sites.

◼️Because of these pathological events peritonitis spreads from the sac to the general peritoneal cavity.

Types of Hernias

◼️ Reducible.. Where the hernia can be reduced when the patient lies down or by the patient himself or by the surgeon, if the contents are intestine, then there is often a gurgling sound at time of reduction, and also the first part is usually more difficult to reduce than the last part, if the contents are omentum, then it will feel as a doughy mass, the last portion is more difficult to reduce than the first one.
◼️ Irreducible.. Refer to a hernia which do not return to the abdomen in absence of any other related symptoms it may occur because of adhesions between the sac and the contents or may occur due to overcrowdening of the sac with contents, such a hernia that doesnt reduce and doesnt produce any symptoms is highly suggestive of omentocele. Note that any degree of irreducibility predispose to strangulation.
◼️Obstructed.
◼️Strangulated.. Can proceed to gangrene within only 6 hours.
◼️Inflamed

What does incarcerated hernia mean?
-See below, I have quoted it.🌚

#Hernia
#Surgery

Bed sore score:

Grade 1: redness erythema not disappear with pressure.
Grade 2: superficial ulcer
Grade 3: superficial and subcutaneous tissue but not through fascia.
Grade 4: deep to muscles and joints.

#Surgery

Reducible swellings:

1-Hernia
2-Meningocele
3-Varicocele
4-Saphena varix.

#Surgery

Swellings which are brilliantly transilluminant:

1-Ranula
2-Cystic hygromaand lymph cyst
3-Hydrocele
4-Meningocele
5-Epididymal cyst (Chinese-lantern pattern)
6Hydrocele of the canal of Nuck.

#Surgery

Cold Abscess:

-It is a soft fluctuant swelling without signs of inflammation, which is mistaken for a cyst.
-This is lined by granulation tissue and caseous material.
-It is due to tuberculous infection and contains tubercle bacilli.
-It is not hot.
-Brawny induration, edema and tenderness are absent.

#Surgery

Acute Abdomen definition:
-Any sudden spontaneous nontraumatic disorder affecting the abdomen for which urgent operation may be necessary and undue delay in diagnosis may adversely affect the outcome.

#Surgery

Swellings that move with deglutition?

1-Thyroid
2-Thyroglossal cyst
3-Subhyoid bursitis
4-Nodes attached to larynx and trachea
5-Laryngocele.

-Ascitic fluid less than 500 cc cannot be detected clinically.

-Minimal Ascites (500-1000cc).
-Moderated Ascites (1000-2000cc).
-Severe Ascitis (>2000 cc)

•Moderate amount: Shifting dullness.
•Tense: transmitted thrill.
•Minimal: knee - elbow.

#Surgery

Fluctuation:
-It's the transmission of an impulse in two directions at right angles to each other, and it implies presence of fluid in the swelling.

#Surgery

Sign of Moulding:

1-Sebaceous cyst
2-Dermoid cyst
3-Colonic mass with faecal matter.

#Surgery

Sleeping pulse rate:
Pulse rate counted early morning around 4 am, before the patient wakes up, without disturbing the sleep.

#Surgery

Symptoms of appendicitis

● Periumbilical colic
● Pain shifting to the right iliac fossa
● Anorexia
● Nausea

Signs to elicit in appendicitis:

● Pointing sign
● Rovsing’s sign
● Psoas sign
● Obturator sign

Clinical signs in appendicitis
● Pyrexia
● Localised tenderness in the right iliac fossa
● Muscle guarding
● Rebound tenderness

The patient is then asked to point to where the pain began and where it moved (the pointing sign).

Types of Hernia.
#Surgery

•Why do we ask the patient to turn his face to opposite side during Expansile impulse on coughing?
-To prevent coughing towards examiner.

•Pubic tubercle may be reached by following the tendon of adductor longus.

•Taxis is gradual reduction of contents of the scrotum by gentle manipulation by flexion, adduction and rotation of hip joint.

#Surgery

Deep ring occlusion test:

-When deep"internal" ring is occluded after reducing the contents, if impulse on coughing is absent in standing position then it is indirect inguinal hernia; if impulse on coughing is still present then it is direct inguinal hernia.

-It is the most important test in inguinal hernia.

-Deep/internal ring is located 1.25 cm above the mid-inguinal point.

-Midinguinal point is mid-point between the anterior superior iliac spine and pubic symphysis.

إذا أدى لك IVP أو KUB ويقول لك هل

x ray
فأيش الفرق بين plain والـ plan ؟
Plain : without contrast
Plan  : with contrast.

Plain X-ray in Acute appendicitis:

May show the following:
-Lumbar scoliosis towards right due to psoas spasm which is not uncommon
-Faecolith on the right side;
-Obliteration of preperitoneal fat line due to retrocaecal appendicitis;
-Segmental ileus in caecum and terminal ileum
-Speckled extraluminal gas in right iliac fossa, gas in appendix,
-Pneumoperitoneum (very rare);
-Intestinal obstruction (occasionally only);
-Soft tissue mass in mass or abscess of appendix.

all these features are very much nonspecific. X-ray is useful to rule out DU perforation, intestinal obstruction, ureteric stone.

Also Radio-opaque appendix in a plain X-ray. It could be calcified or have calcified content.
