Outcomes

Primary Outcome Measures

Post operative pain
Post operative pain, measured with Visual Analogue Scale (VAS) (from 0 to 10 points) World Health Organization (WHO)
Recurrence
Recurrence of inguinal hernia in the one-year follow-up
Complications
Postoperative complications including wound complications (seroma, haematoma, infection), gastrointestinal complications (ileus, fistula), urological complications (acute retention, haematuria) and hernia complications (recurrence, chronic groin pain) will be reported. Occurrence of major complications will be registered, including intestinal injury, major vascular lesion, bleeding over 500cc and peritonitis.

Secondary Outcome Measures

Operating time
Operating time from first incision to closure
Hospital stay
length of hospital stay will be measured in hours between the end of the surgery and the time of discharge.

5. Study Description

Brief Summary
Open prospective randomised clinical trial enrolling women who suffer from inguinal or femoral hernia, to evaluate if TEP approach is superior to TAPP concerning postoperative development, principally postoperative pain, with no increase of recurrent hernia at the one-year follow-up visit.
Detailed Description
Randomised phase IV clinical trial enrolling women suffering from inguinal hernia in Virgen del Rocío University Hospital influence area, from March 2019 to March 2021. The aim of the study is to conclusively stablish whether there is real and significant benefit in using TEP approach over TAPP, in an outpatient basis, concerning postoperative evolution. Secondary objectives are the assessment of postoperative pain, using VAS (visual analogic scale), of both techniques, and evaluation of hernia recurrence during the first postoperative year The individuals will be assigned to each group according to simple random sampling.
