OC-031 TROCAR SITE INCISIONAL HERNIA PREVENTION BY ONLAY MESH PLACEMENT, NOT WHAT WAS EXPECTED

Abstract Aim The prevalence of Trocar site incisional hernia (TSIH) might be as high 30%, due to this reason is paramount find a better closure technique. Our aim test the TSIH preventive effect placement an onlay mesh versus standard fascial at umbilical trocar closure. Material&Methods We designed Two-Center Randomized Controlled Trial where adult participants presenting for elective laparoscopic cholecystectomy, were allocated into 2 groups (Prosthesis and Control). Hasson technique was pneumoperitoneum creation procedure in Prosthesis group consisted complete vertical section aponeurosis by single 0 Polydioxanone stitches, 2cm plane dissection, lightweight, large-pore synthetic its fixation applying cyanoacrylate glue, subcutaneous skin staplers. Control closed stitches followed An ultrasound scan performed 12 postoperative months. Results At 12-month control, 41.7% incidence recorded while 28.5% control group. 6 patients developed superficial wound infection port group, none 5 had operated removal they 4 chronic infections 1 seroma with bad pain control. Conclusions preliminary results study show no benefit prevention presented greater number complications.
