Purpose
Spigelian hernias arise at the linear semilunaris and account for approximately 1–2% of abdominal hernias. The aetiology is due to a defect of the aponeurosis of the transverse abdominis and when discovered, management is surgical intervention. The aim of this study was to observe operative outcomes for open and minimally invasive repair.
Methods
A retrospective chart review was conducted at two hospitals in Townsville, The Townsville University Hospital and The Mater Private Hospital over a 10-year period (2010 to 2020). A surgical database search (ORMIS & IEMR) was performed at both locations using key search terms, including “spigelian hernia”, “laparoscopic”, “open”. Descriptive statistics were utilised to analyse patient factors and operative outcomes in the public and private setting.
Results
43 cases of Spigelian hernias (25 female, 18 male) were reported over the study period. The average age was 66. There were 36 elective cases and 7 emergency cases. A laparoscopic approach was the preferred method of repair, occurring in 74% of cases. Of these cases, the predominant hernial content was fat only. 65% of cases had a history of prior abdominal surgery unrelated to the “Spigelian belt” location. Complications occurred in 19% of cases. Other variables, such as ethnicity, smoking status, defect size, predisposing factors and recurrence rate, were analysed and did not yield statistical significance.
Conclusion
Although a small sample size, the data suggest there is no statistically significant difference between operative outcomes, complication rate and predisposing factors between open and minimally invasive case groups.
