Abdominal Wall Skin Loss Defects Reconstruction Using Pedicled Anterolateral Thigh Flap

Abstract

It was extremely difficult to deal with the complex full-thickness abdominal wall defect post serious trauma. The pedicled anterolateral thigh flap had been reported to be applied in reconstructing full-thickness abdominal wall defect in lower abdomen and groin. However, less cases in upper abdominal wall defect reconstructed by anterolateral thigh flap were reported due to some limitations. The aim of this study was to introduce our experiences in applying anterolateral thigh flap in upper abdominal wall defect reconstructing. In this study, seven patients with a large area of upper full-thickness defect in abdominal wall complicated with multiple organ damage were retrospectively identified due to acute trauma. Immediate organ-repair surgeries were performed. Meanwhile, the patients underwent complete debridement in the zone of abdominal wall defect, together with anti-infective treatment. Then, the appropriate timing was chosen to perform pedicled anterolateral thigh flap for reconstructing large area of full-thickness defect involving the upper abdomen. Postoperative follow-up data demonstrated that all the flaps survived, with no hernia complications or other discomforts. The outcome of the patients was also good. Thus, we conclude that pedicled anterolateral thigh flap was feasible to repair full-thickness defect in upper abdominal wall as long as well designed.
