OPTIMIZATION OF THE CHOICE OF LAPAROSCOPIC AND OPEN ALLOPLASTICS IN CASE OF INCISIONAL VENTRAL HERNIAS

Abstract

The aim of the work – to increase the effectiveness of surgical treatment of incisionalventral hernias (IVH) by optimizing the choice of laparoscopic and open allohernioplasty.Material and methods. The analysis of surgical treatment of 508 patients with IVH from2009 to 2020 was conducted. According to the Europenian Herniology Association(EGA) classification (Ghent, Belgium, 2008) IVH was distributed as follows: MW1-2R0 was diagnosed in 217 (42,7%), MW3R0 – in 291 (57,3%) patients. Diastasis of therectus abdominis muscles up to 5 cm was present in 217 (42,7%) patients, diastasis5-10 cm – in 127 (25%), diastasis greater than 10 cm – in 164 (32.3%) patients.Depending on the size of the hernia and the width of diastasis of the rectus abdominis,patients were divided into 3 groups.In group I, laparoscopic allohernioplasty was performed in 109 (21,5%) patients withsmall and medium-sized IVH with diastasis of up to 5 cm, in particular the developedlaparoscopic preperitoneal in 63 patiens and laparoscopuc retromuscular alloplastiesin 46 patients. The comparison group IIa consisted of 108 (15,1%) patients whounderwent open retromuscular allohernioplasty.In group II, 64 (12,6%) patients with large IVH and diastasis of the rectus abdominis5-10 cm underwent open allohernioplasty by «sublay» technique. The comparison groupIIa consisted of 63 (12,4%) patients who were performed the open method «onlay».In group III, in 82 (16,1%) patients with giant IVH and diastasis more than 10 cm ananterior component separation technique of the abdominal wall in combination withalloplasty with intra-abdominal placement of a mesh implant with anti-adhesive coatingwas performed according to the developed method. Comparison group IIIa consistedof 82 (16,1%) patients who underwent anterior component separation technique of theabdominal wall in combination with alloplasty «onlay».Results. For small and medium-sized IVH and diastasis of the rectus abdominis musclesup to 5 cm, laparoscopic allohernioplasty with preperitoneal and retromuscularplacement of a mesh implant and elimination of diastasis is optimal in comparisonwith open retromuscular allohernioplasty, contributes to a significant decrease in theincidence of seroma from 35,2% to 3,7 %, postoperative wound suppuration – from6,5% to 0%, inflammatory infiltrate – from 4,6% to 0%, chronic postoperative pain –from 6,4% to 2,6%, hernia recurrence – from 6,4% up to 0%.The optimal method of allohernioplasty for large IVH and diastasis of the rectusabdominis muscles from 5 to 10 cm is the open «sublay» technique in comparison withthe open «onlay» technique, reduces the incidence of seroma from 23,8% to 6,3%,postoperative wound suppuration – from 4,8% to 1,6%, chronic postoperative pain –from 4,8% to 1,6%, hernia recurrence – from 7,9% to 3,1%.In case of gigantic IVH, contracture of the rectus abdominis muscles and diastasisof more than 10 cm the anterior component separation technique of the anatomicalcomponents of the abdominal wall in combination with intra-abdominal alloplasty isoptimal in comparison with the use of an anterior component separation techniqueof an abdominal wall combined with «onlay» significant improvement in treatmentoutcomes, namely, reduction of seroma frequency from 25,6% to 7,3%, postoperativewound suppuration – from 4,9% to 2,4%, postoperative wound infiltrate – from 13,4%to 2,4 %, chronic postoperative pain – from 8,1% to 1,6%, recurrence of IVH – from6,5% to 1,6%.Conclusion. Optimization of the choice of laparoscopic and open allohernioplastyenables to increase significantly ventral hernias and to decrease the quantity of thepost-operative complications.
