Acellular allogenic dermis combined with VSD for repair of abdominal wall defect: a case series.

OBJECTIVE

To explore the clinical application of acellular allogenic dermis combined with VSD in repairing abdominal wall defect combined with abdominal infection.

METHODS

Clinical data of 5 cases of abdominal cavity infection with abdominal wall defect admitted in the Burn Department of Quanzhou First Hospital from January 2019 to January 2022 were collected for this study. The abdominal cavity was closed temporarily after debridement and VSD in the early stage, and the abdominal wall defect was repaired by acellular allogeneic dermis combined with autologous split-thickness skin graft in the second stage. The changes of infection indexes (WBC, CRP, PCT, Lac) before and after treatment and the clinical therapeutic effect were observed.

RESULTS

In the 5 observed cases, the infection index decreased significantly, the intra-abdominal pressure was normal, and there was no abdominal wall hernia, intestinal adhesion, intestinal obstruction or any other complications. The wound of abdominal wall defect achieved stage 1 healing, the local scar tissue only has slight proliferation, and the appearance was satisfying. There was no recurrence in 6 months follow-up.

CONCLUSION

Early use of VSD can effectively control abdominal infection and reduce the occurrence of intestinal fistula or other complications. In the later stage of treatment, acellular allogenic dermis combined with autologous split-thickness skin graft can effectively repair abdominal wall defect.
