ABSTRACT: PURPOSE:Groin hernia repair is the most frequently performed general surgical operation in the UK. Complications from laparoscopic and open repair are well recognised; however, potential differences are yet to be considered in relation to litigation. METHODS:Administrative data were obtained and analysed from the NHS Litigation Authority for inguinal hernia-related claims from 1995 to 2016. Claims identified as using an open or laparoscopic approach were compared. RESULTS:880 claims were made, 760 had been settled. 88 laparoscopic and 241 open procedures were identified; 65% laparoscopic and 63% open hernia claims were found to be in favour of the claimant. Payouts totalled to 4.1GBP/4.8EUR/5.3USD million and 9.4GBP/11.0EUR/12.1USD million for laparoscopic (mean 82,824GBP/96,579EUR/106,453USD) and open (mean 66,796GBP/77,892EUR/85,852USD) approaches, respectively. The most common reasons for claim initiation were visceral/vascular injury (54%) in the laparoscopic group, and testicular complications or chronic pain (35%) in the open group. Additional procedures were necessary for 48% and 44% of laparoscopic and open claims, respectively. The highest average payouts were associated with visceral injury, (laparoscopic 116,482GBP/135,820EUR/149,715USD; open 199,103GBP/232,246EUR/255,905USD) and vascular injury (laparoscopic 88,624GBP/103,369EUR/113,892USD; open 64,460GBP/75,163EUR/82,870USD). Additional procedures resulted in an average payout of 93,352GBP/108,917EUR/120,008USD (laparoscopic) and 60,408GBP/70,506EUR/77,657USD (open). The most common additional procedures were corrective visceral/vascular repairs, orchidectomy and recurrent hernia repair. CONCLUSIONS:The rate of litigation for clinical negligence in inguinal hernia surgery in the UK is increasing. Whilst there has been a recent increase in laparoscopic hernia repair claims, the volume and burden of claims related to open procedures remain greater.
