Hernias-Summer_2024

Hernia

Protrusion of a tissue or organ through a defect in the wall of the anatomical cavity in which it normally lies.

True hernia

Hernia with an anatomical hernial sac.

False hernia

Lacks hernial sac; can develop into true hernia with chronicity.

Incarceration

Condition where contents of the hernia are irreducible, potentially leading to strangulation.

Strangulation

Compromised blood supply leading to ischemia and potentially necrosis.

Loss of Domain

Condition in chronic hernias where the normal location is too small to accommodate reduced contents.

Internal Hernia

Hernia occurring through a ring of tissue confined with the abdominal wall or thorax.

Diaphragmatic Hernia

Type of internal hernia occurring through the diaphragm.

Umbilical Hernia

Failure of fusion of rectus abdominis m. at umbilicus; may close spontaneously.

Spontaneous closure of an umbilical hernia occurs before or no later than….

6 months of age.

Open herniorrhaphy is a surgical procedure where the hernia sac is ______ and removed.

incised.

Clinical Signs of Umbilical Hernia

Soft round mass at umbilical scar, often reducible; may have GIT signs if obstructed.

Inguinal Hernia

Type of hernia occurring in the inguinal region, can be congenital or acquired.

Scrotal Hernia

Type of inguinal hernia occurring in males, associated with weakness of the vaginal ring.

Traumatic Abdominal Hernia

Hernias associated with blunt trauma with significant injuries potentially requiring emergency surgery.

Diagnosis of Hernias

Includes thorough history, physical examination, radiographic examination, and ultrasound.

Herniorrhaphy

Surgical repair of a hernia, involving return of contents to normal location and secure ring closure.

Congenital Pathogenesis

Hernias that are hereditary or developmental in origin.

Acquired Pathogenesis

Hernias resulting from traumatic, non-traumatic, or iatrogenic causes.

Treatment of Umbilical Hernia

May involve surgical repair, particularly in larger hernias or when contents are strangulated.

Inguinal Hernia Predisposed Breeds

Includes Basenji, Basset hound, and Cocker spaniel among others.

Post-operative Complications

May include seroma, hematoma, or failure of anatomic closure.

Acute Abdominal Hernia Repair

Repair involving ventral midline approach; allows exploration of abdomen.

Chronic Abdominal Hernia Repair

Allows better anatomic closure and exploration.

Cranial Pubic Ligament Avulsions

Often associated with pubic/pelvic fractures, complicating repair.

Incisional Hernia

Hernia that occurs due to improper surgical technique or patient factors.

Diagnosis of Incisional Hernia

May include exaggerated swelling or serosanguinous discharge persisting after surgery.

Hernial Sac

The membrane-like cover that encapsulates the herniated contents.

Ventral Hernia

Hernia occurring along the ventral surface of the body.

Congenital Hernias

Hernias present at birth or developing shortly thereafter.

Acquired Hernias

Hernias developing due to external factors or incidents.

Reducible Hernia

A hernia where the contents can be returned to the abdominal cavity.

Irreducible Hernia

Hernia that cannot be pushed back into the abdominal cavity.

Strangulated Hernia

An irreducible hernia with compromised blood flow to the contents.

Body Wall Hernia

Hernia occurring through the musculature of the body wall.

Obstruction in Hernia

Blockage of contents, often leading to vomiting and severe pain in patients.

Tension-free Closure

Surgical technique avoiding tension on surrounding tissues during hernia repair.

Suture Material for Herniorrhaphy

Absorbable materials preferred for secure closure of hernias.

Hernial Ring

The opening in the wall of the cavity through which the hernia protrudes.

Compartment Syndrome

Condition where increased pressure within a confined space leads to muscle and tissue damage.

Prepubic Tendon

A ligament in the ventral abdominal wall, relevant in certain hernias.

Umbilical Mass Clinical Sign

Symptoms indicating an umbilical hernia, typically soft and round.

Advanced Imaging Techniques

Utilized for detailed examination during hernia diagnosis.

Ring Closure in Herniorrhaphy

Returning the hernial ring to a closed position after repair.

Exaggerated Swelling Post-surgery

Common sign indicating possible incisional hernia.

Ventral Midline Approach

Surgical access method for abdominal surgeries including hernia repair.

Traumatic Hernias

are initially false; will develop hernial sac with chronicity

What is closed herniorrhaphy?

Closed herniorrhaphy refers to a surgical technique for hernia repair where the hernia sac is not incised, and the procedure is performed through a minimally invasive approach.

What are the benefits of closed herniorrhaphy?

Benefits of closed herniorrhaphy include reduced risk of infection, less postoperative pain, and quicker recovery time compared to traditional open techniques.

What conditions may warrant closed herniorrhaphy?

Closed herniorrhaphy may be suitable for certain types of hernias that are reducible and not strangulated, particularly in patients with lower surgical risks.

What instruments are typically used in closed herniorrhaphy?

Common instruments for closed herniorrhaphy include laparoscopic tools such as trocars, graspers, and suturing devices, which assist in performing the procedure through small incisions.

What is the role of imaging in closed herniorrhaphy?

Imaging techniques such as ultrasound or CT scans may guide the surgeon in planning the procedure and confirming reduction of the hernia.
