The radical cure of hernia may be attempted at the operation for strangulated hernia under specific conditions. For non-emergency cases, family doctors should recommend surgery only for small, reducible, congenital hernias in young men with well-developed abdominal walls and easily controlled by a truss. Large or irreducible hernias are difficult to handle and may lead to recurrence or severe complications.
Surgical anatomy involves understanding the inguinal canal and its structures, including the cord containing the vas deferens and accompanying vessels and nerves. The operation aims to reconstruct the posterior wall of the inguinal canal and restore obliquity. General anesthesia is preferred, although local and spinal are alternatives.
The primary incision begins at the external ring and extends downward and forward to the pubic spine. After skin and subcutaneous tissues are divided, fatty tissue layers are removed down to the aponeurosis of the external oblique. The pillars of the ring must be exposed thoroughly before proceeding with further dissection.
To find and dissect out the sac, one should carefully divide the aponeurosis along the line of the pillars and then search for the hernial sac within the cord's sheath. Once identified, the sac is isolated to its internal ring, ligated, and amputated. The abdominal walls are sutured next, followed by closing the wound with chromic catgut sutures.

The final step involves suturing the skin wound with silk gut, possibly including a drainage tube if infection risk exists. Postoperative care includes monitoring for signs of infection or complications.

Key Takeaways
- Radical surgery for inguinal hernias should only be attempted under specific conditions and by experienced practitioners.
- Proper patient selection is crucial to ensure successful outcomes and minimize complications.
- Aseptic techniques are essential to prevent infection, which can lead to recurrence or other serious issues.
Practical Tips
- Ensure the patient's hernia is small, reducible, and congenital for optimal surgical results.
- Use general anesthesia as it provides better control over the surgical procedure.
- Carefully identify and isolate the hernial sac to prevent future complications.
Warnings & Risks
- Large or irreducible hernias are difficult to manage surgically and may lead to severe injury or recurrence.
- Improper handling of the vas deferens and accompanying structures can cause significant damage during dissection.
- Failure to properly ligate and amputate the sac increases the risk of peritoneal diverticulum formation.
Modern Application
While surgical techniques have advanced since 1915, the principles outlined in this chapter remain relevant. Proper patient selection, meticulous aseptic technique, and careful dissection are still critical for successful hernia repair. Understanding these historical methods provides valuable insights into modern surgical practices.
Frequently Asked Questions
Q: What is the ideal age range for undergoing inguinal hernia surgery according to this chapter?
The chapter recommends that the ideal patient is a young man between fifteen and twenty-five years old with well-developed abdominal walls.
Q: Why is it important to ligate and amputate the sac within half an inch of the ligature?
Ligating and amputating the sac close to the ligature prevents recurrence by eliminating any potential for peritoneal diverticulum formation, which can lead to another hernia.
Q: What are the risks associated with not properly isolating the hernial sac during surgery?
Improper isolation of the sac may result in a peritoneal diverticulum, leading to future complications such as recurrence or infection.
