Study Notes

Herniology: Etiology, Pathogenesis, and Surgical Approaches

  • Modern herniology utilizes precise anatomical knowledge and extensive practical experience, deeply investigating etiological factors and pathogenesis.
  • Various surgical techniques are critically analyzed, selecting the most reliable and pathologically sound.
  • Research in hernia repair continues both domestically and internationally. Key researchers include prominent figures like I.I. Kukudzhanov, N.V. Voskresensky, and many others.
  • Herniotomy, often a beginner surgeon's first operation, is not a simple procedure.
  • Even common inguinal or femoral hernia repairs, if performed incorrectly, can cause nerve entrapment, vessel damage, urinary bladder injury, and wound infections.

Historical Context

  • Knowledge of hernias and their management dates back to antiquity, with references in works by Hippocrates, Galen, and Celsus.
  • Celsus provided the classical definition of hernia.
  • Early operative manuals were primitive due to the limited anatomical understanding.
  • Advances in anatomical research in the latter half of the 20th century provided theoretical underpinnings for modern herniology.
  • Key figures in surgical advancements include A. Cooper, F. Messelbach, C. Langenbeck, and P. Zabolotsky, and later A.A. Bobrov and N.V. Bogoyavlenskiy.
  • The discovery of anesthesia, and the introduction of asepsis and antiseptics were crucial to progress.
  • Y. Champinniere performed the first plastic operation for inguinal hernia repair in 1885.

Clinical Picture of Incarcerated Hernias

  • Incarcerated hernia is characterized primarily by sudden pain in the hernial area and sometimes the entire abdomen.

  • Pain intensity, character, and location differ for individuals based on the type of incarceration, impacted organ, age, and other factors.

  • In older patients, pain might be subtle compared to young patients who may experience severe pain, tachycardia, and decreased blood pressure.

  • In more advanced/severe conditions, pain is constant, increasing and/or cramping.

  • A critical diagnostic feature is the inability to reduce the hernia.

  • Enlargement, intensified pain, and morbid nature of the hernia are common.

  • Dullness or tympanic sounds on percussion may indicate fluid buildup or intestinal distension, respectively.

  • Irreducible hernias show sudden pain, tenderness, and rigidity without cough shock symptom transfer.

  • Vomiting often accompanies incarceration.

  • Pains related to wearing a bandage might be misconstrued, thus requiring detailed inquiries.

  • Incarceration in elderly patients might show initial hyperperistalsis that quickly turns to intestinal paresis, resulting in abdominal bloating that lacks signs of peritoneal irritation.

  • Signs of peritonitis (deteriorating general health, weakness, thirst, rapid pulse, temperature rise) are more obscure in older patients versus young.

  • Incorrect diagnoses can be attributed to inflammation of inguinal lymph nodes, metastases, abscess processes, or varicose veins.

Surgical Approach to Incarcerated Hernias

  • Immediate surgical intervention is necessary for strangulated hernias, with the only exception being the agonal state.

  • Forcibly reducing incarcerated hernias is inadmissible, due to the risk of hemorrhage, vessel thrombosis, mesentery rupture, or intestinal perforation.

  • Ventral hernias comprise 8-18% of surgical hospital admissions, with inguinal hernias representing a significant portion.

  • Inguinal hernias are prevalent in males due to anatomical/structural differences. (Inguinal canal structure)

  • Oblique and direct hernias are the main types; rarer variants include oblique hernias with direct canal, preperitoneal, intraparietal, encysted, periinguinal, supravesical, and combined hernias.

  • "Difficult" or "complex" forms of inguinal hernias, such as large, irreducible, sliding, recurring, or repeatedly recurring hernias, are also distinguished.

  • Congenital and acquired oblique inguinal hernias are classified based on the origin of the hernial sac.

  • Oblique inguinal hernias follow the inguinal canal's path, descending into the scrotum, forming an inguinoscrotal hernia.

  • Chronic inflammation in the vermiform appendix may complicate presentations with lower abdominal pain, constipation, nausea, and decreased appetite.

  • In female patients, hernias may involve internal reproductive organs, causing abdominal pain that radiates to the pubic region.

  • Surgeons should assess hernia size and shape in various patient positions, particularly during palpation and in relation to the inguinal canal.

  • Oblique hernias present as elongated protrusions along the inguinal canal, possibly extending to the scrotum; direct hernias are typically spherical or oval, closer to the pubic area.

  • Periinguinal or interwall hernias may be indicated when the protrusion is above the inguinal canal opening.

  • Large inguinal hernias in males reveal significant scrotum enlargement, skin stretching, and displacement or disappearance of the penis.

  • Detailed palpation to assess hernia size, reducibility, internal canal size, and testicle details is crucial.

  • Differential diagnostics between direct, oblique, and femoral hernias is necessary.

  • The cough shock symptom (jerky pressure) is important for early or canal hernias diagnosis

  • Recurrence of inguinal hernias is a significant concern in conventional procedures, and is associated with techniques that disregard topographical and hernia type specificity.

  • Certain complex forms (e.g. large inguinal, sliding hernias) have high relapse rates.

  • Reliable rebuilding and closure of the posterior inguinal wall is a key factor for low hernia recurrence rates.

  • For severe cases with extensive or repeatedly recurring hernias, rebuilding or creating a new inguinal canal might be necessary, utilizing autoplastic reconstruction or additional materials.

  • Surgeons should strive to maintain the natural anatomical location and function.
