Inguinodynia in patients after inguinal hernioplasty with the Lichtenstein technique with resection versus preservation of the ipsilateral ilioinguinal nerve
PDF size: 81.66 Kb.
ABSTRACTObjective: To assess inguinodynia in patients after Lichtenstein-type inguinal plasty, comparing section of the ilioinguinal nerve against its preservation.
Setting: Hernia Clinic of the General Surgery Service at the General Hospital of Mexico.
Design: Controlled double-blind clinical trial.
Statistical analysis: Wilcoxon and Mann-Whitney U tests.
Material and methods: Forty patients were subjected to Lichtenstein inguinal plasty; randomly, in 18 patients the ilioinguinal nerve was sectioned and preserved in 22 patients. We evaluated pre and postoperative cutaneous sensitivity, intensity of pain was assessed through a visual analog scale, to determine whether sectioning the ileoinguinal nerve dicreases or not the intensity of pain and presentation of postoperative inguinodynia.
Results: There was a significant difference in pain reduction in favor of patients, in whom the nerve had been sectioned, starting at 24 h after surgery (p ‹ 0.001) and at 60 days after surgery (p ‹ 0.0001), without presenting inguinodynia, allodynia, nor distress due to hypoesthesia or anesthesia.
Conclusion: Section of the ilioinguinal nerve during inguinal hernia repair with the Lichtenstein technique decreases optimally the postoperative pain, without altering importantly surface sensitivity and avoids inguinodynia.
