2. Definition Reducible Non-reducible ( incarcerated) Strangulated
Internal
External
Interparietal

3. Location Umbilicus Lumbar triangles Linea alba (epigastric)
Surgical incisions
Semi-lunar line
Diaphragm
Pelvis

4. Umbilical Hernia Women> men(3/1) Incidence:10%
more common in African American children
Risk factors
Obesity
Pregnancy
abdominal distension
ascites

5. Richter’s hernia
incarceration of a portion of the wall of the small bowel in a hernia.

6. Lumbar Hernia Congenital, spontaneous or traumatic
Grynfeltt’s triangle
12th rib, internal oblique and sacrospinalis muscle
Covered by latissimus dorsi
Petit’s triangle
Latissimus dorsi, external oblique and iliac crest
Covered by superficial fascia

7. Lumbar Hernia Develops at Petit’s Triangle
Between abdominal and back muscles
Fascia in this region is thin

8. Littre’s hernia
hernia containing a Meckel’s diverticulum.

9. Epigastric hernia In midline Between xiphoid and umbilicus
Incidence 3-5%
Men> women(3/1)
12% multiple
Etiology: multiple factors:
congenitally weakened linea alba from a lack of decussating midline fibers
increase in intra-abdominal pressure
surrounding muscle weakness
chronic abdominal wall strain

10. Spigelian Hernia occurs along the semilunar line Rare
Ultrasound examination&ct scan
operative repair is mandatory once the hernia is confirmed on diagnosis

11. Pelvic Hernia Obturator hernia Sciatic hernia Perineal hernia
Most commonly in women
Howship-Romberg sign
Sciatic hernia
Perineal hernia

12. Obteratour hernia …… Very rare Seen in elderly, emaciated patients
Develops in obturator fossa
Not visible or palpable on outside
Can strangulate, cause bowel obstruction ……

13. Incisional Hernia Risk factors Laparoscopic . open repair
Gold standard

15. Parastomal Hernia Variant of incisional hernia
Paracolostomy > paraileostomy
Low rate if through rectus muscle
Laparoscopic repair

16. Hiatal hernia
