Efficiency assessment of laparoscopic vs open alloplasty for incisional ventral hernias

Abstract

Materials and methods. During the period from 2009 to 2020 in the clinic of the Department of Surgery and Proctology of the Shupyk National Healthcare University of Ukraine, the surgical treatment of 217 patients with IVH was analysed.

The choice of laparoscopic hernioplasty or open allohernioplasty was made taking into account the size of the abdominal wall defect and the width of the rectus diastasis. By intraoperatively conducting a study during a surgery for IVH with an abdominal rectus diastasis involving approximation of the rectus muscles and measurement of IAP, it was found that with an abdominal rectus diastasis measuring up to 5 cm IAP increases to 5.6 ± 1.3 mm Hg and the abdominal wall defect is closed without an undue tension of the supporting tissues.

Depending on the method of surgical treatment, patients were divided into 2 groups.

In group I, 109 (21.5%) patients with small and medium-sized IVH with a diastasis of up to 5 cm underwent laparoscopic allohernioplasty, in particular, 63 patients underwent laparoscopic preperitoneal alloplasty and 46 underwent laparoscopic retromuscular alloplasty.

Conclusions. For small and medium-sized IVH with an abdominal rectus diastasis of up to 5 cm, laparoscopic allohernioplasty with preperitoneal and retromuscular placement of the mesh implant and elimination of the diastasis is optimal. In comparison with open retromuscular allohernioplasty, it contributes to a significant reduction in the incidence of seroma (from 35.2% to 3.7%), postoperative wound suppuration (from 6.5% to 0%), inflammatory infiltrate (from 4.6% to 0%), chronic postoperative pain (from 6.4% to 2.6%), and recurrence of hernia (from 6.4% to 0%).
