Comparison of mesh fixation and non-fixation in laparoscopic inguinal hernia repair

Comparison of fixation and non-fixation of mesh in laparoscopic repair of inguinal hernia

Clinical trial, with parallel groups, two-way blind, randomized , About 100 patients who randomized by the blocking method and using online software www.sealedenvelope.com .

100 patients who are candidates for laparoscopic inguinal hernia surgery in Vali-e-Asr Hospital in Arak are divided into two groups. The study is double-blind and the intervention will be performed in the operating room while the patient is under general anesthesia and the patient and the outcome evaluator and data analyzer are not aware of the study groups. The first group will insert the mesh without fixing it in the peritoneum and the second group will insert the mesh by fixing it to the peritoneum. Then, after the surgery, the desired outcomes will be evaluated and compared in two groups.

Inclusion criteria: Candidate for laparoscopic inguinal hernia repair surgery. exclusion criteria: liver, kidney, heart disease, history of drug use, chronic analgesia

In the non-fixed mesh group, after surgery, the patient will have a fibrin mesh at the hernia site in the peritoneal wall and the two edges of the peritoneum will be fused at the surgical site, but the mesh will not be fused to the peritoneum. But in the second group, after surgery for the patient in the final stage, after placing a fibrin mesh at the site of the hernia in the peritoneal wall, in addition to the two edges of the peritoneum will be screwed on it at the surgical site, the mesh itself will be screwed to the peritoneum.

Pain, urinary retention, length of hospital stay

In this study, 100 patients who meet the inclusion criteria will be divided into two completely equal groups (50 people) using block randomization method and online software www.sealedenvelope.com and using 10 blocks of 10. . Concealment will be done using the sealed opaque envelope method. In this way, the created sequences will be placed in pots with dark cover and will be sealed, and in order to maintain a random sequence, the numbering on the outer surface of the envelopes will be done in the same way. Finally, the lids of the letter envelopes are glued and placed inside a box, respectively. At the beginning of the registration of participants, according to the order of entry of eligible participants into the study, one of the envelopes of the letter is opened in order and the assigned group of the participant is revealed.

This study will be double-blind. In this way, patients will be meshed in the operating room during anesthesia for both groups and patients will not be aware of the type of meshing performed. Also, the outcome assessor recognizes the study groups only on the basis of the letters A and B and is not aware of the intervention performed, and only the surgeon and the resident resident are aware of the study groups and the type of their intervention.
