Abdominal wound dehiscence after appendectomy during pregnancy treated by negative pressure wound therapy with subsequent vaginal delivery: A case report and literature review

Negative pressure wound therapy (NPWT) is a very effective method in the treatment of dehiscent, infected, and non-healing wounds. Difficult wound healing occurs especially in late pregnancy due to the rapid enlargement of the uterus and the constantly increasing tension of the entire abdominal wall. In cases of dehiscence of the surgical wound during pregnancy, proper subsequent treatment is needed, where it is necessary to consider the safety of the mother as well as the fetus. We report the case of a 30-week pregnant patient who was surgically treated for acute appendicitis in pregnancy with an open appendectomy approach. Postoperative complications resulted in wound dehiscence with complete defect in fascia, which was treated with negative V.A.C. ATS (R) Therapy System. The therapy was started in the 30th week of pregnancy and continued until delivery with regular check-ups and regular redressing of the vacuum-assisted closure (VAC) system. At 38 weeks of pregnancy, the patient delivered vaginally with continued VAC therapy in situ. The final suture took place 3 days after vaginal delivery. Non-healing wounds with abdominal wall defects should be treated using a multidisciplinary approach, and NPWT can be used. This therapy can also be used during pregnancy. Vaginal delivery is preferred because it reduces the risk of further formation or deepening of the abdominal wall defect after a sufficient time interval from the start of the treatment. This complex case with a literature review of surgical complications in pregnancy treated with NPWT therapy highlights the advantage of a multidisciplinary approach.
