Randomized Controlled Trial Multicenter Study
Prolene Hernia System, Lichtenstein mesh and plug-and-patch for primary inguinal hernia repair: 3-year outcome of a prospective randomised controlled trial. The BOOP study: bi-layer and connector, on-lay, and on-lay with plug for inguinal hernia repair.
Dissection requirements differ between various methods for inguinal hernia repair, which may affect operation times, pain response and possibly recovery time. The objectives of this study were to establish if any differences concerning these aspects could be detected following three principally different techniques for primary inguinal hernia repair. ⋯ All of the techniques are suitable for operation under local anaesthesia. The PHS and P techniques can be performed with shorter operation times than the L method. Early and late outcomes are, however, comparable, with no significant differences concerning complication rates, return to full functional status and/or pain response.

Comparative Study
Laparoscopic inguinal total extraperitoneal hernia repair under spinal anesthesia without mesh fixation in 1,220 hernia repairs.
The need for general anesthesia and the cost and pain due to metal staples required for fixing the mesh are the major reported disadvantages of laparoscopic total extraperitoneal (TEP) hernia repair. We studied the feasibility and results of TEP done under spinal anesthesia with non-fixation of the mesh (SA-NF). This group was compared to TEP done under general anesthesia with non-fixation of the mesh (GA-NF) and repairs done under SA with fixation of the mesh (SA-F). ⋯ TEP, done under SA and without fixation of the mesh, is safe, feasible, and associated with low recurrence rates. Since this procedure does not have the disadvantages usually attributed to TEP, it can be possibly recommended as a first-line procedure, even for unilateral inguinal hernias. Further studies are needed to substantiate this.

Comparative Study
Comparison of ultrasonography with computed tomography in the diagnosis of incisional hernias.
The objective of this study is to determine the reliability and validity of ultrasonography (US) in diagnosing incisional hernias in comparison with computed tomography (CT). The CT scans were assessed by two radiologists in order to estimate the inter-observer variation and twice by one radiologist to estimate the intra-observer variation. Patients were evaluated after reconstruction for an abdominal aortic aneurysm or an aortoiliac occlusion. ⋯ US imaging has a moderate sensitivity and negative predictive value, and a very good specificity and positive predictive value. Consistency of diagnosis, as determined by calculating the inter- and intra-observer Kappa statistics, was good. The incidence of incisional hernias is high after aortic reconstructions.

Laparoscopic ventral hernia repair (LVHR) is a well established procedure in the treatment of ventral hernias. It is our clinical experience that patients suffer intense postoperative pain, but this issue and other recovery parameters have not been studied in detail. ⋯ LVHR was associated with considerable postoperative pain and fatigue in the first postoperative month, prolonging the time of convalescence and significantly affecting patients' quality of life up to 6 months postoperatively. Mesh fixation with fibrin glue or other non-invasive/degradable products seems promising for reducing pain and it should be investigated in future randomised trials.

Randomized Controlled Trial Comparative Study
Pre-emptive infiltration of Bupivacaine in laparoscopic total extraperitoneal hernioplasty: a randomized controlled trial.
To investigate the effectiveness of pre-emptive preperitoneal infiltration of 0.5% Bupivacaine in postoperative pain control in laparoscopic total extraperitoneal (TEP) hernioplasty. ⋯ Pre-emptive preperitoneal infiltration of 0.5% Bupivacaine significantly reduces postoperative pain in laparoscopic TEP hernioplasty.
