Background
The incidence of chronic pain after endoscopic hernia repair varies between 1 and 16 %. Studies regarding the course of pain in time after the operation are scarce.
Methods
473 male patients ≥18 years of age, scheduled for totally extraperitoneal (TEP) hernia repair (Prolene® mesh) between March 2010 and August 2012 were requested to record pain symptoms preoperative, and 1 day, 1 week, 6 weeks, 3 months and 1 year postoperatively and visit the outpatient department 3 months and 1 year postoperatively for a standardized interview and physical examination.
Results
Preoperatively, 25 % (n = 114) of the patients had moderate-to-severe pain (NRS 4–10). Six weeks postoperatively, 3 % (n = 12) of the patients still experienced moderate-to-severe pain. Three months after TEP, only 3 patients (0.6 %) had moderate-to-severe pain, while 83 patients (18 %) experienced mild pain. One year after TEP, 39 patients experienced mild pain (8 %) and 3 patients moderate pain (0.7 %), no patients experienced severe pain after 1 year. Patients with moderate-to-severe pain preoperatively had a higher risk of pain persisting until 3 months and 1 year postoperatively (p = 0.03). In most patients who had pain 3 months postoperatively and were pain-free 1 year after TEP, pain ‘faded out’ at 4–6 months postoperatively. Two patients had a not-painful recurrent hernia, diagnosed 2 and 5 months after TEP repair.
Conclusion
Moderate-to-severe pain after TEP hernia repair is self-limiting, with less than 1 % of the patients reporting moderate pain 1 year postoperatively.
