Meta Analysis Comparative Study
A meta-analysis of randomized controlled trials of fixation versus nonfixation of mesh in laparoscopic total extraperitoneal inguinal hernia repair.
Mesh fixation during laparoscopic total extraperitoneal (TEP) inguinal hernia repair is still controversial. Although many surgeons considered it necessary to fix the mesh, some published studies supported elimination of mesh fixation. Therefore, a meta-analysis based on randomized controlled trials (RCTs) was conducted to compare the effectiveness and safety of fixation versus nonfixation of mesh in TEP. ⋯ Without increasing the risk of early hernia recurrence, the nonfixation of mesh in TEP appears to be a safe alternative that is associated with less costs, shorter operative time, and hospital stay for the selected patients. Further adequately powered RCTs are required to clarify whether mesh fixation is necessary for the patients with different types of hernias and larger hernia defects.
