Hernia Repair

Part of Surgery

Surgical correction of hernias to prevent strangulation and restore abdominal wall integrity.

Why This Matters

A hernia occurs when abdominal contents (typically intestine) protrude through a defect in the abdominal wall. Inguinal (groin) hernias are among the most common surgical conditions in men worldwide. Umbilical, incisional, and femoral hernias are also common. Most hernias are not immediately dangerous — they are an inconvenience and a dull ache. But a hernia that becomes incarcerated (stuck) or strangulated (blood supply cut off) becomes a life-threatening emergency within hours.

In post-collapse conditions, hernias will be common. Heavy labor, malnutrition weakening the abdominal wall, and unmanaged pregnancy complications all predispose to hernias. Without surgical repair, every person with a hernia lives with the risk of strangulation — sudden severe pain, inability to reduce the hernia, vomiting, and eventual bowel death and perforation if untreated. Teaching a community healer to identify and repair hernias prevents many preventable deaths.

The repair itself — in its simplest form — requires only a sharp instrument, suture material, knowledge of anatomy, and adequate anesthesia.

Understanding Hernia Types

Inguinal Hernia

The most common type, especially in men. Intestine (or other contents) pushes through the inguinal canal in the groin. The inguinal canal is a natural passage in the lower abdominal wall through which the spermatic cord passes in men.

Direct inguinal hernia: protrudes directly through a weak point in the posterior wall of the inguinal canal. Associated with age and weakness.

Indirect inguinal hernia: follows the path of the spermatic cord through the internal inguinal ring. More common in younger men and can be congenital.

Physical exam: a bulge in the groin crease, more prominent when standing, coughing, or straining. May extend into the scrotum in men.

Umbilical Hernia

Protrusion through the umbilicus. Common in infants (usually resolves spontaneously by age 2); in adults often related to pregnancy, obesity, or ascites.

Femoral Hernia

Protrusion through the femoral canal (below the inguinal ligament, at the upper thigh). More common in women. Higher risk of strangulation than inguinal hernias.

Incisional Hernia

Protrusion through a previous surgical wound. Preventable through good fascial closure technique.

Assessing the Hernia

Is It Reducible?

Reducible: contents can be pushed back through the defect with gentle pressure. This is the safe state — not an emergency.

Irreducible (incarcerated): contents cannot be reduced back. May or may not have blood supply compromise. Requires urgent assessment.

Strangulated: blood supply to the herniated contents is compromised. True surgical emergency.

Signs of strangulation:

• Sudden increase in pain at the hernia site
• Hernia becomes firm and tender to touch
• Overlying skin may become red or discolored
• Nausea, vomiting
• Systemic features: fever, rapid heart rate

Timing: strangulated bowel dies within 4-6 hours. Every hour of delay worsens the prognosis.

Attempting Reduction of Incarcerated Hernia

Before rushing to surgery, attempt manual reduction:

1. Patient lies supine with hips and knees flexed (reduces abdominal wall tension)
2. Apply gentle, persistent pressure on the hernia directed toward the defect
3. A small amount of sedation (if available) helps relax the abdominal wall
4. Cool the hernia with cold water compress — reduces swelling
5. Apply gentle compression for 5-10 minutes

If successful: the hernia reduces with a gurgling sensation. Patient experiences immediate relief. Elective surgical repair should follow within days — it will reoccur.

If unsuccessful after 15-20 minutes of sustained effort: proceed to surgery.

Do Not Reduce Forcefully

Forced reduction of a strangulated hernia can push dead bowel back into the abdomen, causing peritonitis from bowel perforation. If the hernia is very painful, discolored, or the patient has been sick for more than a few hours, proceed directly to surgery rather than risking forced reduction of dead bowel.

Surgical Repair: Inguinal Hernia

Anesthesia

Inguinal hernia repair can be performed under local anesthesia with sedation — an advantage when general anesthesia is not available.

Local anesthesia field block: Inject local anesthetic (1% lidocaine if available, or dilute cocaine solution) into the skin and subcutaneous tissue along the planned incision line. Also infiltrate deeper into the inguinal canal itself. Allow 5-10 minutes for anesthesia to develop.

Incision and Anatomy

1. Mark the incision: 2-3 cm above and parallel to the inguinal ligament (the ligament running from hip bone to pubic bone), centered over the hernia bulge
2. Incise skin and subcutaneous fat
3. Identify the external oblique aponeurosis (a white, glistening fibrous sheet) — incise along its fibers to expose the inguinal canal
4. Identify the spermatic cord in men (a white cylindrical structure containing vas deferens, blood vessels, nerves)
5. The hernia sac is a peritoneal protrusion — it appears as a white or bluish tissue around or adjacent to the cord

Hernia Sac Management

Indirect hernia sac:

1. Carefully separate the sac from the cord — dissect the tissue between them using scissors and blunt dissection
2. Open the sac — identify contents (intestine should appear pink and healthy; if dark/purple/black, consider strangulation)
3. Reduce the contents back into the abdomen
4. Twist the sac neck tightly and ligate at the base (pass a suture around the twisted neck, tie firmly)
5. Cut the sac off below the ligature

Direct hernia sac: The sac here represents a weakness in the posterior wall. The sac itself is often not isolated — the repair focuses on reinforcing the posterior wall.

Posterior Wall Repair (Bassini Repair)

The key step — closing the defect and reinforcing the posterior wall of the inguinal canal:

1. Using strong non-absorbable suture, suture the conjoint tendon (internal oblique and transversus abdominis muscles) to the inguinal ligament
2. Interrupted sutures placed 1 cm apart, from medial (near pubic bone) to lateral
3. This narrows the internal ring and reinforces the posterior wall
4. The spermatic cord lies over this repair

A simpler repair (Marcy repair) for indirect hernias only: Simply suture the internal ring tightly around the cord — a purse-string or 2-3 interrupted sutures to narrow the ring to a snug fit around the cord. Less durable but quicker and technically easier.

Closure

1. Close the external oblique aponeurosis over the cord with continuous absorbable suture
2. Close subcutaneous tissue with a few interrupted absorbable sutures
3. Close skin

Strangulated Hernia Repair

If bowel in the hernia is strangulated:

1. Open the sac carefully
2. Assess bowel viability: pink and contractile = viable; purple, black, or non-contractile = dead
3. If dead bowel: do not push back into abdomen. Requires bowel resection and anastomosis — major surgery (see abdominal surgery article)
4. If viable bowel (pink after releasing constriction for 5 minutes): reduce it, close the sac, repair the defect

Post-Operative Care

• Pain is typically moderate for 5-7 days
• Light activity (walking) can begin day 2
• Avoid heavy lifting for 6-8 weeks
• Heavy manual labor for 8-12 weeks

Recurrence rates without mesh: traditional tissue-only repairs (Bassini) have 10-15% recurrence. In a post-collapse setting without mesh, this is acceptable — a secondary repair is possible.

Complications to watch for:

• Wound infection: treat with drainage and cleaning
• Hematoma (blood collection): usually resolves spontaneously; drain if large
• Testicular swelling or atrophy: spermatic cord injury during dissection — minimize handling of the cord

The relief of successful hernia repair is immediate and dramatic for the patient. For those who have lived with a painful reducible hernia, repair restores full function. For those who presented with strangulation, it can be life-saving.
