Inguinal hernia is a very common disease and it is more frequent in elderly than in younger patients. The incidence rises from 11 per 10,000 person-years aged 16-24 years to 200 per 10,000 person-years aged 75 years and above [1]. Inguinal hernia repair is one of the most commonly performed operations worldwide [2]. Moreover the demand for surgical services for inguinal hernia is increasing due to an increase of an ageing population [3]. This pathology causes aching discomfort and an unsightly swelling and it is established that hernioplasty gives patients a remarkable improvement of quality of life also in geriatrics [35]. In addition, a routine elective operation allow us to avoid acute complications like strangulation, intestinal obstruction, and infarction that are the most important complications of untreated hernia, and are potentially life-threatening [6].

According to the literature the safest approach to geriatric patients is to perform hernioplasty in open surgery [7] using local anaesthesia [8, 9] but some authors suggests that it is better to take a watchful waiting approach especially in asymptomatic patients [10, 11]. In our study we evaluate the impact of hernioplasty in local anesthesia in patients younger and older than 70 years. We compared the frequency of complications and comorbidity in the two groups in order to verify the feasibility and safety of this approach in elderly.


In the study we included patients with inguinal hernia that reached our department in the period between June 2009 and July 2012. Patients with recurrence, bilateral hernia, large size hernia and all cases that underwent general anaesthesia were excluded from the study. A total of 218 hernioplasties were performed by resident surgeons in local anaesthesia, 98 of these were patients under 70 years and 120 patients were over this age. All procedures were performed as described by Rutkow and Robbins [12] or with Lichtenstein techniques with standard-weight polypropylene mesh [13]. Prophylactic antibiotics were not used [14]. American Society of Anaesthesiologists (ASA) grade 1 and 2 patients underwent deep sedation (midazolam, fentanyl) combined with a field block of local anaesthesia (lidocaine without adrenaline) and were monitored by pulse oximetry. For ASA grade 3 and 4 patients procedures were performed in the presence of the anaesthetist and deep sedation was not used [9, 15, 16]. Comorbidity was registered in the pre-operative time. After surgery patients were examined after 1 week and a second time after 1 month in order to evaluate the presence of post-operative complications.


None of the 218 procedures were complicated by any side-effects due to the anesthetic techniques or any other procedure-related complication and there were no deaths. There was a higher rate of comorbidity in the group of over 70 years of age. The main associated illnesses that were observed are: benign prostatic hypertrophy (BPH 60% in over 70 and 30% in under 70), cardiovascular diseases ( CD 50% in over 70 and 22% in under 70), hypertension ( 25% in over 70 and 8.16% in under 70), chronic obstructive pulmonary disease (COPD; 12.5% in over 70 and 6.12% in under 70). Other comorbidities that we found were obesity, diabetes, hepatic cirrhosis and renal failure [ Table 1]. Intraoperative complications that occurred were severe bleeding (5 cases) and arrhythmia (3 cases). Post-operative complications that occurred were: recurrence (12 cases), wound infection (11 cases),nerve entrapment (10 cases), mesh infection (6 cases), urinary retention (5 cases), and wound hematoma (4 cases). There was a slightly higher rate of complications in the elderly group, in fact recurrence occurred in 7.5% of older versus 3.6%, wound infections 6.6% versus 3.6%, mesh infection in 3.3% versus 2.04%, urinary retention in 3.3% versus 1.02% [Table 2]. Overall the complication rate is not particularly high even in patients who have a higher percentage of comorbidity.

Table 2 Complications


Elective inguinal hernia repair under local anesthetic has a good outcome also in the elderly even if there are significant comorbidities. The slightly higher rate of complications that occurred in older patients is not significant and does not support advising against the use of this surgical approach in elderly. So in our opinion hernioplasty under local anesthesia is quite safe and feasible also in patients over 70 years.
