Table 23. Key Question 2b: Treatment details

Study / Treatment A / Treatment B /
Champault et al., 1997651-654 / TEP, prior experience with TEP of this surgeon was 50 cases (to confirm feasibility and serve as a training period for the members of the surgical team). General anesthesia, direct inflation of the Retzius space using carbon dioxide with a Veress needle. One mesh if unilateral, two if bilateral. mesh was polypropylene (Ethicon) slit on the lower edge to allow passage of the spermatic cord, mesh not fixed. First 11 patients had 11x6 cm mesh, last 89 patients had 15x13 cm mesh. / Stoppa (prior Stoppa experience of surgeons not reported), general anesthesia, dissection of the preperitoneal space from one psoas muscle to the other, Dacron mesh (Ethicon) 30x15 cm with a lower edge slit to allow passage of the spermatic cord, mesh not fixed.
Douek et al., 2003674,675 / TAPP, general anesthesia, 10x15 cm polypropylene mesh (Prolene, Ethicon), stapled in position with the EMS multifeed staple gun. Peritoneum was replaced to exclude the mesh from the cavity and stapled in position. For bilateral cases, either two meshes were used, or a single 28x10 cm mesh. / Lichtenstein, local anesthesia, no other details reported
Ozmen et al., 2010779 / TEP as described by Begin using four trocars, general anesthesia. Insufflation with 12 nnHG carbon dioxide after balloon dissection. Both sides of the hernial sac were reduced and 10x15cm Prolene mesh (Ethicon) inserted without making any keyhole and fixed to Cooper’s ligament, the anterior abdominal wall, and the iliopsoas muscles using a total of 5-8 tacks. / Stoppa method using a giant V-shaped polypropylene mesh (Ethicon). general anesthesia. Hernial sac reduced or ligated. 10x15 cm Prolene mesh fixed to the pubis and Cooper’s ligament with 1 or 2 stitches.
Sarli et al., 2001801 / TAPP “bikini mesh” repair. Pneumoperitoneum was established. Peritoneum overlying the inguinal regions was divded transversely from the medial umbilical ligament to a point on the iliopubic tract 2 cm lateral to the internal inguinal ring. Upper and lower peritoneal flaps created. Single piece of polypropylene mesh 30x10 cm (no splits) to cover the spermatic cords, spermatic vessels, and all hernial orifices, passing into the cave of Retzius between the bladder and the pubis. mesh tacked to Cooper’s ligament and transversalis fascia using 4-6 titanium staples at each side. mesh was fully reperitonealized. / Lichtenstein as described by Amid. No mesh details provided.
Suter et al., 2002819,820 / TEP as described by Begin using four trocars, maximum insufflation pressure of 10 mmHG, and two slit 14x14 cm polypropylene meshes (Ethicon) / Stoppa method using a giant V-shaped polypropylene mesh (Ethicon).
Wara, 2008829-834 / TAPP in 91.7%; TEP in 8.3%. “Six of 33 hospital departments reported more than 50 laparoscopic repairs per year whereas 21 departments performed fewer than 20 repairs annually.” / Lichtenstein, no other details reported
