Emergency groin hernia repair: implications in elderly

Background Groin hernia is one of the most frequently encountered pathologies occurring in old age and it is often the cause of emergency procedures. In our study we evaluate the impact of emergency procedures in over 75 patients compared to younger patients. Methods We conducted a retrospective study about patients who underwent emergency hernioplasty between September 2007 and January 2013. Bilateral hernias and recurrences were excluded. We divided patients into two groups by age (under and over 75 years old) and then analyzed the early postoperative surgical complications. Results A total of 48 patients were enrolled, 18 were included in under 75 group and 30 in over 75. In the older group we found a higher rate of comorbidity and also a significant higher rate of postoperative complications. Two patients of over 75 group died. Conclusions Our data suggests that a quick diagnosis and elective surgical procedures are desirable in order to avoid the complications that occur in emergency operations.


Background
Groin hernia is more frequent in elderly patients, conditions which increase intraabdominal pressure and the loss of strength of the abdominal wall, play a determinant rule in that [1][2][3][4]. In fact the abdominal wall increasing is due to the presence of constipation, prostatism, bronchitis (coughting) or abdominal fat deposit that may affect old patients, furthermore the loss of strength of the abdominal wall is caused by alteration in collagen (the collagen becomes more rigid and crystalline and its tension diminished) typical of elderly [2,5,6]. Also the ageing population is increasing, with a corresponding increasing demand for surgical services [7]. Elective groin hernia repair is a surgical procedure with good results and minimal morbidity and recent studies suggest that it is quite safe [8][9][10][11]16,17]. Despite this is still widely thought that in elderly is better a conservative approach [7,12], but excessive waiting times for elective repair increase the risk of strangulation, bowel resection and mortality especially in older patients [13,14]. Also the higher rate of comorbidity in combination with the usage of general anesthesia in old patient increases the risk of complications [7,15]. In our study we evaluate the impact of emergency groin hernia repair in over 75 patients compared to younger patients.

Methods
In this retrospective study we included patients who underwent emergency hernioplasty in our department in the period between September 2007 and January 2013. We divided patients into two age classes (under and over 75 years old). Exclusion criteria were: previous surgery for groin hernia, bilateral inguinal hernia, connective tissue disease, immunocompromised host. For incarceration we intend irreducibility of a groin hernia and for strangulation we intend a irreducible hernia with objective signs of ischemia or gangrene. General anesthesia was induced and maintained in all patients using standard techniques. Perioperative intravenous antibiotic prophylaxis was given, usually cefazoline, and antibiotics were then continued orally until the end of the first postoperative week in all patients [4,14]. The Lichetenstein hernioplasty was done by resident surgeons [18,19]. Patients were discharged when they were ambulating with minimal pain and had no fever. Followup was made at 1 week and 4 weeks postoperatively.

Results
A total of 48 patient were enrolled, 18 were included in under 75 group and 30 in over 75. Thus, 14 patients were male and 9 were female. In 17 cases we treated an incarceration, in 25 cases a strangulation and 6 cases required a bowel resection (5 of them in the elderly group). Comorbidity found were higher in over 75 group (Table 1)

Conclusions
In conclusion, our data suggest that acutely incarcerated or strangulated groin hernia in elderly is a serious problem because of the high morbidity and mortality rate found in the over 75 group that are, in our opinion, unacceptable. So quick diagnosis and elective surgical procedures are desirable in order to avoid the complications that occur in emergency operations, moreover elderly patients should be warned about the potential danger of groin hernia emergency repair.
