Study type
Interventional
Description of intervention(s) / exposure
Modified darn repair:
The procedure started by taking the first stitch on the pubic tubercle using O polypropylene. The thread was passed through the inguinal ligament and the internal oblique fascia fibres in a continuous tension free manner. Suturing was proceeded from medial to lateral in a crisscross pattern with 1 cm interval between each suture. On reaching the cord at the deep ring, care was taken to pass the sutures around the cord with no pressure, then the sutures are ligated 2-3 cm lateral to the deep ring. Security sutures (2-O monofilament polypropylene) were taken in a continuous manner starting at the pubic tubercle and passing through the edges of the repair at the inguinal ligament and the internal oblique fascia fibres and through the loops of the previous sutures. Procedure duration is about (60 - 120 minutes)
Intervention code [1] 285320 0
Treatment: Surgery
Comparator / control treatment
Lichtenstein procedure; polypropylene mesh is applied over the fascia transversalis after herniotomy and narrowing of the deep ring. mesh is then fixed to pubic tubercle, internal blique fascia fibres and inguinal ligament. laterally, a small openning is made in the mesh through which the cord passes then the mesh is resutured laterally to create another deep ring. Procedure duration is about (60 - 120 minutes)

Eligibility

male patients with primary inguinal hernia classified as Gilbert III or IV
Minimum age
18 Years
Maximum age
60 Years
Gender

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
closed envelope technique
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
a total number of 152 envelopes were divided into 76 modified darn repair and 76 Lichtenstein Procedure. Envelopes are completely sealed and shuffled. An investigator with no clinical involvement in the trial and is blinded to the procedure chooses one envelope just before the surgery and inform the surgeon with the procedure to be done.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
Randomization was done immediately before performing the precedue. so the surgeon knows the procedure just before the operation
