Etymology of hernia

  1. 1. Etymology of Hernia Jibran Mohsin Resident, Surgical Unit I SIMS/Services Hospital, Lahore
  2. 2. Etymology • Hernia means – ‘To bud’ or ‘to protrude’, ‘off shoot’ (Greek) ‘Rupture’ (Latin)
  3. 3. Parts of Hernia • Sac – diverticulum of peritoneum with mouth, neck, body and fundus. – Neck is narrow in indirect sac but wide in direct sac • Hernia without neck: Those hernias with larger mouth lack neck, e.g. direct hernia, incisional hernia – Body of the sac is thin in infants, children and in indirect sac but is thick in direct and long standing hernia. – Hernia without sac: • Epigastric hernia—it is protrusion of extra-peritoneal pad of fat • Covering – layers of the abdominal wall through which the sac passes
  4. 4. Parts of Hernia • Contents – Omentum—Omentocele (Epiplocele). Difficult to reduce the sac later, initially it can be reduced easily. – Intestine—Enterocele— commonly small bowel, but sometimes even large bowel. Difficult to reduce the sac initially. – Richter’s hernia: A portion of circumference of bowel is the content. – Urinary bladder may be the content or part of the posterial wall of the sac—cystocele. – Ovary, often with fallopian tube. – Meckel’s diverticulum—Littre’s hernia – Fluid: • secreted from congested bowel or omentum or • infected fluid or • ascitic fluid or • blood from the strangulated sac.
  5. 5. Clinical Classification • Reducible hernia – Reduced on its own or by patient or by surgeon – Expansile cough impulse positive • Irreducible hernia – Contents can’t be returned to abdomen due to • narrow neck, • adhesions(incarcerated), • overcrowding – Predisposes to strangulation Enterocele Reduces with gurgling difficult to reduce 1st portion Omentocele doughy difficult to reduce last portion
  6. 6. Clinical Classification • Obstructed hernia – Lumen of gut present in the hernial sac gets obstructed like any intestinal obstruction – NOT seen in omentocele or richter’s hernia • Inflamed hernia – Inflammation of contents of sac – e.g. appendicitis and salpingitis – Tender but NOT tense with red and edematous overlying skin • Strangulated hernia – Compromised blood supply – Tense as well as tender with no cough impulse – Associated with obstruction in case of enterocele (exception: Richter’s hernia)
  7. 7. • Garrey’s Stricture – Constriction due to ischemic narrowing of small bowel which has reduced from an obstructed hernia
  8. 8. Richter’s Hernia • Portion of antimesenteric border of gut gets incarcerated and eventually strangulated without obstruction of lumen in the hernial orifice • segment of the engaged bowel is nearly always the lower portion of the ileum – but any part of the intestinal tract, from the stomach to the colon, including even the appendix
  9. 9. Richter’s Hernia • Precondition for the formation of this particular hernia, as stated by Richter, is determined by the size and consistency of the hernial orifice – big enough to ensnare the bowel wall, but small enough to prevent protrusion of an entire loop of the intestine – margin of the hernial ring must be firm or, in Richter’s words, “possess strong spring-force.
  10. 10. Richter’s Hernia • Tend to progress more rapidly to gangrene than ordinary strangulated ones – firm constricting ring that exerts direct pressure on the bowel wall – free border of the intestine opposite the mesentery with the predominance of terminal arterioles that is involved – late diagnosis or even misdiagnosis, thus allowing time for bowel necrosis to develop. • Also seen at site of laparoscopy port site – Thus incidence might increase with time – Especially if fascia not closed at 10 mm port site
  11. 11. Richter’s Hernia • first description of a case of Richter’s hernia was made by Fabricius Hildanus (1560–1634) in 1606 – illustrates a typical clinical presentation of a perforated Richter’s hernia • In his famous Treatise on the Ruptures in 1785, August Gottlob Richter (1742–1812) gave the first comprehensive description of hernias in which only part of the circumference of the bowel is strangulated, and termed them “the small ruptures.”
  12. 12. Richter’s Hernia • The nomenclature of this hernia subsequently resulted in confusion • Only 100 years later, in 1887, did the famous London surgeon Sir Frederick Treves distinguish these types of hernias from herniation of a Meckel diverticulum, which was classically described by Littre. • Treves credited Richter with the distinction of having given the first scientific description of this particular lesion and suggested the term Richter’s hernia, – “(partly) because with Richter must rest the main credit of establishing the individuality of this lesion.” Sir Frederick Treves (1853–1923)
  13. 13. Richter’s Hernia • 10% of strangulated hernias are Richter’s hernias (5–15%) • 60 to 80 years old – but cases have been described even in infants • In whites, the most common site is the femoral ring (36– 88%), – followed by the inguinal canal (12–36%) and abdominal wall incisional hernia (4–25%). – Rare sites, such as umbilical, Obturator, supravesical, spigelian, triangle of Petit,sacral foramen, Morgagni, internal,or (traumatic) diaphragmatic hernias
  14. 14. Richter’s Hernia • since the first description of a Richter’s-type herniation through a laparoscopy incision in 1977 – similar case reports have increasingly been published
  15. 15. Busoga Hernia • variety of direct inguinal hernia common in the Busoga area of Uganda and some other African countries, including South Sudan and Ghana where it particularly occurs in women. • caused by a narrow defect in the conjoint tendon or transversalis fascia and consequently there is a risk of strangulation. – The neck of the sac is small, so that when strangulation occurs, often only part of the circumference of the gut is involved causing what is known as a Richter's hernia
  16. 16. Littre’s Hernia (persistent omphalomesenteric duct hernia) • Alexis de Littre (1700) reported ileal diverticula and attributed them to traction. – report three cases of incarcerated femoral hernia containing a small bowel diverticulum • August Gottlieb Richter (1785) defined them as preformed, and • Johann Friedrich Meckel (1809) postulated their embryologic origin. • Sir Frederic Treves (1897) distinguished between Littre and Richter hernia (partial enterocele) Johann Friedrich Meckel (1781–1833), German anatomist
  17. 17. Litre’s Hernia • also described the mucous urethral glands of the male urethra (littre’s gland) • first to suggest the possibility of performing a lumbar colostomy for an obstruction of the colon • Jean Louis Petit was one of his students. So was Jacques-Bénigne Winslow in 1707 Alexis Littré (1654 – 1726) French physician and anatomist
  18. 18. • Meckel's diverticulum an out-pouching of the ileum, part of the small intestine, and found in approximately 2% of the population.(1809) • Meckel's cartilage A cartilaginous bar from which the mandible is formed. Described in 1820. • A syndrome – Meckel syndrome – is also named after him. This condition was described in 1822. • A protein – mecklin – the gene for which is found on chromosome 8 (8q21.3-q22.1) is named after him.
  19. 19. Amyand Hernia • rare form of inguinal hernia in which the vermiform appendix is located within the hernial sac. • Seen in < 1% of inguinal hernia • Claudius Amyand (1681-1740), French born English surgeon – performed the first successful appendectomy in 1735, on an 11-year-old boy who presented with an inflamed, perforated appendix in his inguinal hernia sac
  20. 20. De Garengeot Hernia • appendix-containing incarcerated femoral hernia • Akopian and Alexander, named this hernia after the 18th century Parisian surgeon Rene Jacques Croissant de Garengeot(1688-1759). – He is quoted in the surgical literature as the first to describe this situation in 1731.
  21. 21. Maydl's hernia (Hernia-in-W) • hernial sac contains two loops of bowel with another loop of bowel being intra-abdominal – loop of bowel in the form of 'W lies in the hernial sac and the centre portion of the 'W loop may become strangulated, either alone or in combination with the bowel in the hernial sac – more often seen in men, and predominantly on the right side • Postural or manual reduction of the hernia is contra- indicated as it may result in non-viable bowel being missed Karel Maydl (1853 –1903) Austrian surgeon
  22. 22. Gibbon’s Hernia Hernia with Hydrocele Edward Gibbon (1737–1794) English historian and Member of Parliament Suffered from hydrocele; Due to in fashion close fit clothing his conditions lead to chronic and disfiguring inflammation followed by numerous surgeries, last 3 of which lead to peritonitis and eventually death

Thin, consists of three layers—outer amniotic membrane, middle Wharton’s jelly and inner peritoneal layer Non-rotation and intestinal atresia are common associations. Cardiac anomaly is not common as in omphalocele. often associated with congenital anomalies of cardiac and genitourinary system - 70%.

  97. 97. Rectus abdominis diastasis (diastasis recti, abdominal separation) (Divarication of rectus abdominus Muscles-DRAM) • a separation of the two rectus abdominis muscle pillars • results in the characteristic bulging of the abdominal wall in the epigastrium • sometimes mistaken for a ventral hernia – despite the fact that the midline aponeurosis is intact and no hernia defect is present
  98. 98. Rectus abdominis diastasis (diastasis recti, abdominal separation) (Divarication of rectus abdominus Muscles-DRAM) • Congenital – as a result of a more lateral insertion of the rectus muscles to the ribs and costochondral junctions • Acquired – advancing age – obesity, or – Post-partum • advanced maternal age • after multiple or twin pregnancies • high-birth-weight infants Diastasis: Greek Separation
  99. 99. Internal Hernia • Occur when the intestine (the ‘viscus’) passes beneath a constricting band or through a peritoneal window (the ‘defect’) within the abdominal cavity or in the diaphragm. • They present as – Acute intestinal obstruction, with or without intestinal ischaemia, perforation and peritonitis, or – Chronic recurrent abdominal pain and vomiting due to incomplete and intermittent intestinal obstruction. • Sites of internal herniation include – (i) the paraduodenal and paracaecal fossae, – (ii) the lesser sac through the epiploic foramen (foramen of Winslow) or a defect in the transverse mesocolon, – (iii) beneath congenital bands or adhesions, – (iv) through defects in the small bowel mesentery, – (v) between the lateral abdominal walls and intestinal stomas, and – (vi) through defects in the diaphragm (hernias of Bochdalek and Morgagni).
