P012 RISK FACTORS FOR INCISIONAL HERNIA AND ITS RECURRENCE: OBSERVATIONAL, AMBISPECTIVE STUDY

Abstract

Abstract Aims In patients with herniorrhaphy treated in a 3rd level hospital in the Southwestern of Colombia from January 2014 to March 2020, determine the frequency of incisional hernia recurrence and the risk factors related to. Materials and methods Observational, ambispective study that included patients older than 15 years with a history of incisional hernia that agreed to participate and signed a consent form. Patients with incomplete data or who underwent surgery in another institution were excluded. Follow-up appointments every 3 months were made to evaluate the incidence of hernia recurrence. Results 112 patients were included, 64.3% female with a mean age of 58.6-year-old. The frequency of recurrence was 38.4% with a mean of appearance of 22.9 months; 44.2% were repaired with only one technique and 39.5% with non-mesh. Non-use of mesh increased the risk for recurrence (RR 2.02; CI95%: 1.17-3.48). Other risk factors were urgent surgery (RR 1.82; CI95%: 1.14-2.91), defect closure with multifilament suture (RR 1.61; CI95%: 1.15-2.25), not do adhesiolysis (RR 3.17; CI 95%; 0.85 – 11.76) and the no use of postoperative antibiotics (RR 1.67M CI95%: 0.97-2.89). Conclusions Incisional hernia recurrences increase with time. Therefore, a follow-up of at least for 3 years should be guaranteed to avoid undiagnosed cases. Risk factors identified like absorbable multifilament sutures and non-use of the mesh must be removed from the surgery plans. Furthermore, a specialized in-hospital group of the abdominal wall and an institutional protocol would help to diminish this complication.
