Scientific title	The Total Extra Peritoneal (TEP) method versus the Transinguinal Preperitoneal Technique (TIPP) for inguinal hernia repair: A multicentre randomised controlled trial.
Study acronym	GLADIOLA
Study objectives	TIPP has less adverse events than TEP. Further reading: The Tilburg double blind randomised controlled trial comparing inguinal hernia repair according to Lichtenstein and the transinguinal preperitoneal technique. Trials. 2009 Sep 25;10:89. http://www.ncbi.nlm.nih.gov/pubmed/19781069 http://www.controlled-trials.com/isrctn93798494 More information on hernia, treatment and research can be found at http:// www.liesbreukcentrumbrabant.nl
Ethics approval(s)	METC judgement: waiting for approval
Health condition(s) or problem(s) studied	Inguinal hernia
Intervention	As of 04/01/2012 the status of this record was changed to 'stopped' as the trial never started. 900 patients will be randomly allocated to anterior inguinal hernia repair according to the transinguinal preperitoneal technique (TIPP) or totally extra peritoneal (TEP) technique, both with soft mesh. The total duration of follow-up will be one year, post-operatively.
Intervention type	Procedure/Surgery
Primary outcome measure(s)	1. Incidence of adverse events 2. Chronic pain (Visual Analogue Score [VAS]) Data will be collected by VAS-diary and SF36-list (Health Status / Quality of Life). Digital forms will be filled in by the patients at the outpatient departments at 14 days, 3 months and one year after surgery.
Key secondary outcome measure(s)	1. Costs 2. Quality of life (SF-36) 3. Return to daily activities 4. Return to work Data will be collected by VAS-diary and SF36-list (Health Status / Quality of Life). Digital forms will be filled in by the patients at the outpatient departments at 14 days, 3 months and one year after surgery.
