How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

INTRODUCTION: Reconstruction after resection of advanced stage hidradenitis suppurativa is currently performed with pedicled perforator flaps, that allow functional reconstruction and preservation of shoulder function. Skin availability is limited by the possibility of closing the donor site primarily. Bilateral cases need to be treated in two stages, since the operation is carried out in the lateral decubitus. In this manuscript the application of bilateral and bipedicled DIEAP flaps to bilateral and extensive cases is presented. PATIENTS AND METHODS: Between October 2008 and October 2018, 39 patients were treated for axillary hidradenitis suppurativa. Of these, 11 patients had bilateral reconstruction with bilateral DIEAP flaps (22 flaps) and one patient had unilateral reconstruction with a bipedicled DIEAP flap. 23 flaps were used. Twelve flaps were raised above Scarpa's fascia, 6 flaps werethinned after dissection. Three flaps were not thinned in the first stage. Average flap size was 14 × 17cm for the bilateral flaps, while the bipedicled flap was 15 × 32cm. RESULTS: Average operative time was 324 minutes. No flap necrosis was observed. Two patients had wound dehiscences in the axilla and one in the abdomen, all treated conservatively. One patient had a pyoderma gangrenosum at both surgical sites that healed after cortisone therapy. No revisions were needed for the flaps that were thinned during the primary operation. The three patients whose flaps where not thinned needed liposuction after three months for thinning. There was one disease recurrence, unilateral and treated surgically. Mean follow up was 64 months. CONCLUSIONS: Axillary reconstruction with the DIEAP flap allows reconstruction of large and bilateral defect in a single operation closing the donor site primarily. If the flap is thinned during the operation, no thinning seems to be needed postoperatively. Otherwise the flap shall be thinned by liposuction three months after the initial procedure. We believe that the benefits of this technique outweigh the added complexity of a microsurgical procedure when bilateral resections are needed, the defects are too wide to close the donor site of a pedicled flap primarily and the lower abdomen is free of disease.
