Abstract
This study compared local (LA) and general anaesthesia (GA) for elective inguinal hernia repair with specific reference to older people (≥70 years). A total of 470 inguinal hernia repairs were compared for demographics, operating time, day case rates and complications. Subgroup analysis was performed to evaluate outcomes in 70 years. A total of 288 LA and 182 GA repairs were performed. One hundred and forty-four (30.6%) patients were older than 70 years of which 80 (55%) were ASA (American Society of Anaesthesiologists) grades 3 and 4. Older (≥70 years) ASA grade 3 and 4 patients are more likely to undergo surgery under LA than GA (63% LA, 35% GA, P = 0.005) with higher day case rates of 81% LA, 33% GA, P = 0.0001). No significant difference in early complications, satisfaction rate and long-term recurrence rates were noted between the two groups. LA inguinal hernia repair has significant short-term advantages and facilitates day surgery in older patients. LA should be the preferred option in the older patients.
