Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Inguinal henri repair is among the most common operations performed by general surgery. The use of laparoscopy in inguinal hernia repair is becoming more common day by day. Laparoscopic inguinal hernia repair is being applied with increasing frequency due to its advantages such as reducing postoperative pain, providing early return to work and increasing patient satisfaction. Due to the widespread use of laparoscopic inguinal hernia repair, the best fixation method for the patches has become an increasingly questionable subject. It is thought that fixation of the patch with staples or clips may reduce the slippage of the patch, thus reducing the risk of hernia recurrence. In addition, it has been stated that the use of these fixation materials will both increase the cost and cause acute and chronic pain after surgery. In some studies in the literature, it was determined that not detecting the patch in laparoscopic inguinal hernia repair did not increase the recurrence. There are some studies showing that failure to fix the patch causes patch slippage in unilateral laparoscopic inguinal hernia repair. In this study, it was planned to investigate the rate of displacement of the patches fixed with staples in patches that do not require fixation in laparoscopic inguinal hernia repair surgeries, compared to the ones that were not fixed, and whether they cause recurrence. At the same time, whether the staples used for patch fixation increase postoperative pain will be evaluated with VAS (visual analog scale) at the postoperative 1st day, 1st month and 6th month after the operation, compared to the group without stapler patch fixation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

72 patients who underwent laparoscopic inguinal hernia repair (Total Extraperitoneal repair) for unilateral inguinal hernia in Fatih Sultan Mehmet Training and Research Hospital General Surgery Clinic will be included in the study. The number of samples was calculated by performing impact power analysis. Informed consent form and voluntary consent form will be obtained from all patients.

A fixation-free patch (Medtronic Dextile Anatomical mesh, USA) will be used in all patients and the patients will be divided into 2 groups containing 36 patients. 1 patch fixation stapler will be placed on the pubic protrusion in the first group (Covidien ProTack Fixation Device 5mm, USA), no fixation material will be used in the second group. Randomization will be provided by determining which patient will be included in which group on the website www.randomiser.org. In all patients, 2 metallic clips (Covidien Endo Clip II Auto suture, USA) will be placed on the superomedial and inferomedial patch borders on the placed mesh, and patch slippage will be evaluated by determining the locations of the clips by superficial ultrasonography at the end of the surgery, at the 1st and 6th months after the surgery. Superficial USG will be performed by the researchers and no expense will be charged to the SSI. Visual Analogue Scale pain assessment questionnaire will be applied to all patients in the postoperative period and the results will be recorded. Patients will be evaluated in terms of inguinal hernia type (direct, indirect), age, gender, hernia size, previous lower abdomen surgery, and additional diseases. The surgeon and the patient performing the ultrasonographic evaluation will not know in which cases the patch has been detected, so the study will be designed as double-blind.

Patients with contraindicated general anesthesia, previous lower abdominal surgery, coagulopathy, iguinoscrotal hernia, incarcerated or strangulated hernia, with a lateral-medial hernia greater than 3 cm and a drain placed will not be included in the study.

Surgical technique: After the infraumbilical 1 cm camera trocar is placed, 2 5 mm working trocars will be inserted through the line alba. After the CO2 insufflation, a 30° camera will be used and the surgery will be performed under 12 mmHg CO2 pressure. After opening the preperitoneal area with the help of blunt dissection, the hernia sac will be clearly revealed and released. All patients will be evaluated peroperatively for the presence of direct and indirect hernia, by clearly demonstrating the spermatic cord structures and normal anatomy. Then, a fixation-free patch (Medtronic Dextile Anatomical Mesh, USA) will be placed on the defect area and fixed on the pubis in one group and not fixed in the other group. It will be ensured that the patch overflows at least 3-4 cm from the defect area. Before the patch is placed in the preperitoneal area, 3 pieces of 10 mm Medium Endo Clips (Covidien Endo Clip II Auto suture, USA) will be placed on the superomedial, inferolateral and inferomedial border. Then, after bleeding control, the layers will be closed in accordance with their anatomy.

The distances between the 3 clips placed at the end of the operation will be measured vertically and horizontally by USG and recorded as x and y values. Ultrasonographic evaluations of the patient will be performed by a surgeon trained in inguinal region Ultrasound.

During the statistical analysis, Mann-Whitney U, Student's T test, Pearson's Chi Square test and Fisher's test will be used where appropriate. Statistically significant p value will be taken into account when it is greater than 0.05.
