OBJECTIVES OF THIS LESSON
• To prepare surgeons to perform a proper surgical repair of an inguinal hernia using the Lichtenstein technique:– by describing the operative technique
• General plan of our lesson- anaesthetic options/ application of local anaesthesia- optimum surgical approach- how to handle the nerves- the indirect sac- the direct sac- mesh placement- closure- common pitfalls- further reading

ANAESTHETIC OPTIONS
• Anaesthetic options– general anaesthetic– spinal anaesthetic– local anaesthetic
• Local anaesthetic- patient must be prepared to be awake- there are few contraindications- particularly useful in older patients and those with co-morbidity- caution with younger, anxious patients and those with irreducible or partially
reducible hernias

OPERATIVE TECHIQUE - HOW TO HANDLE THE NERVES
• Visualise and protect the ilio-inguinal, ilio-hypogastric and genital branch of the genito-femoral nerves throughout the operation

OPERATIVE TECHIQUE – CLOSURE
![Page 20: OBJECTIVES OF THIS LESSON To prepare surgeons to perform a proper surgical repair of an inguinal hernia using the Lichtenstein technique: – by describing.](https://reader035.fdocuments.net/reader035/viewer/2022062719/56649ed45503460f94be492a/html5/thumbnails/20.jpg)
OPERATIVE TECHIQUE – COMMON PITFALLS
• Opening external oblique aponeurosis- Care should be taken to avoid opening the aponeurosis too close to the rolled
edge of the inguinal ligament• Dissection of the sac
- Ensure that the dissection is carried out on the sac itself to avoid damaging adherent cord structures
- Transect a fixed scrotal sac• Mesh fixation
- Ensure adequate medial overlap of the mesh- Avoid the ilio-hypogastric nerve when securing the lateral edge of the mesh
