简要总结
Postherniorrhaphy groin pain is defined as pain lasting greater than 3 months after hernia surgery, which is one of the most important complications occurring after inguinal hernia repair.The overall incidence has been reported to be as high as 35% with an average of 10% patients reporting their pain as moderate to severe intensity. Preemptive regional nerve block (ilioinguinal & Iliohypogastric) has been found to reduce severity of acute postoperative pain and opioid consumption. However, its role in prevention of chronic pain is unclear. We hypothesize that Ultrasound-guided ilioinguinal iliohypogastric nerve block has the potential to reduce the incidence of chronic groin pain at 3 months.
