NCT05061264

Brief Summary

The use of synthetic mesh to repair infected defects of the abdominal wall remains controversial. This study aimed to evaluate the short-term outcomes of using PVDF mesh to treat infected abdominal wall defects in the elective setting.

Outcome Measures

Primary Outcomes (2)

  • Surgical site occurence

    any surgical infection, wound breakdown, soft tissue ischemia, seroma, and hematoma formation

    30 days

  • Surgical site infection

    as an infection occurring where the surgery took place and was further defined as superficial, deep, and organ space

    30 days

Secondary Outcomes (2)

  • Hernia recurrence

    6 and 36 months

  • Infection recurrence

    6 and 36 months

Other Outcomes (1)

  • Microbiology of mesh infection

    30 days

Study Arms (2)

Active infection group

EXPERIMENTAL

A cohort of 38 patients carrying an active infection (mesh sinus, exposed mesh or enteric fistulas) resulting from a previous hernia repair, with or without an associated recurrent ventral hernia, and submitted to abdominal wall reconstruction with PVDF mesh.

Procedure: Abdominal wall reconstruction

Clean control group

ACTIVE COMPARATOR

A cohort of 38 patients with ventral hernias, and submitted to clean ventral hernia repair with PVDF mesh.

Procedure: Abdominal wall reconstruction

Interventions

The repair of abdominal wall defects with polyvinylidene (PVDF) mesh

Also known as: Ventral hernia repair
Active infection groupClean control group

Eligibility Criteria

Age20 Years - 86 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Study group: patients with the presence of an active chronic mesh infection (non-healing sinus, exposed mesh, or mesh-related enteric fistulas) resulting from a previous repair, or the presence of an enteric/enteroatmospheric fistula, with or without an associated abdominal wall defect
  • Control group: patients with a primary or recurrent ventral hernia without previous history of infection and eligible for clean operations

You may not qualify if:

  • giant ventral hernias with a volume ratio higher than 25% and loss of domicile
  • patients on immunosuppressive therapy or using corticosteroids
  • patients with portal hypertension
  • patients with Chron´s disease
  • acute postoperative mesh infection
  • chronic mesh infections following inguinal hernia repair
  • emergency operations.
