Tension-free repair in the preperitoneal space using modified surgical mesh for inguinal hernia： a prospective randomized study

Abstract

Objective To summarize the experience of tension-free repair for inguinal hernia in the preperitoneal space using modified surgical mesh. Methods From Dec 2008 to May 2010, 134 cases with 138 reducible primary inguinal hernia were randomly divided into two groups. Sixty-seven patients （70 hernias） in the study group underwent tension-free repair in the preperitoneal space by modified surgical mesh, while the control group （67 cases, 68 hernias） underwent Rutkow＇s herniorrhaphy by surgical mesh.Results Postoperatively 127 cases （95%） were followed up from 2 to 18 months with an average of 9. 2months[64 cases of the test group were followed up with an average of（9 ±4） months, 63 cases of the control group followed up with an average of （9 ± 5 ） months]. There was no recurrence. No significant differences were found between the two groups in the operation time （P = 0. 697）, blood loss （P = 0. 318 ）,hospital stay （P = 0. 116） and total postoperative complications （P = 0. 080）. The visual analogue scale of the study group was lower than the scale of the control group （ P = 0. 048 ）. Conclusions Modified surgical mesh is more comfortable in the treatment of inguinal hernia with tension-free repair in the preperitoneal space with a comparative result to Rutkow＇s herniorrhaphy by surgical mesh.
