Brief summary

The study attempts to quantify the relative risks for chronic postoperative inguinal pain (CPIP) depending on different combinations of mesh and mesh fixation. For this purpose the investigators will analyze data from the Swedish Hernia Registry (SHR).

Detailed description

This is an open cohort study design where the investigators will analyze existing data that have been prospectively collected in the Swedish Hernia Registry (SHR), which covers \> 95% of all groin hernia repairs in Sweden. The very large cohort of approximately 25,000 primary TEP (totally extraperitoneal) and TAPP (transabdominal preperitoneal) repairs enable assessment of the relative risks for CPIP depending on different combinations of mesh and mesh fixation. Each participant was entered at the date of surgery when demographic and intraoperative data were registered. The possible presence of CPIP after 1 year postoperative was evaluated with a PROM questionnaire.

Interventions

PROCEDURETEP

Laparoendoscopic totally extraperitoneal mesh repair of groin hernia

PROCEDURETAPP

Laparoscopic transabdominal mesh repair of groin hernia

PROCEDUREOther or unspecified laparoendoscopic groin hernia repair

Other refers to any laparoendoscopic mesh repair specified as not being either TEP or TAPP, eg, intraperitoneal onlay mesh (IPOM).
