- W3116241502 abstract "Objective: To explore the methods of repairing large soft tissue defect with latissimus dorsi myocutaneous flap and the management of secondary wound in donor site. Methods: From June 2015 to June 2019, 30 patients with soft tissue defect caused by various reasons or hyperplastic scar were hospitalized in the First Medical Center of Chinese PLA General Hospital, including 10 males and 20 females, aged 25-64 years, with 18 cases of head soft tissue defects caused by the growth and rupture of tumor, 7 cases of hypertrophic scar in trunk and limbs, and 5 cases of facial and neck soft tissue defects caused by trauma. The area of primary wound after debridement or enlarged lesion resection was 14 cm×10 cm-18 cm×16 cm. Preoperative evaluation of 20 patients showed that the wound was relatively large, and the donor site could not be directly closed by suturing after resection of conventional single-lobe latissimus dorsi myocutaneous flap, so the bilobed latissimus dorsi myocutaneous flap with area of 14 cm×5 cm-18 cm×8 cm was cut to repair the wound, and the donor site was directly closed by suturing. Preoperative evaluation of 10 patients showed that the donor site could be directly closed by suturing after resection of conventional single-lobe latissimus dorsi myocutaneous flap, so that conventional single-lobe latissimus dorsi myocutaneous flap with area of 11 cm×9 cm-13 cm×10 cm was resected to repair the primary wound, resulting in big tension in donor site and secondary wound with area of 6 cm×4 cm-8 cm×6 cm that couldn't be directly sutured, which was repaired with donor site local flap with area of 7 cm×4 cm-9 cm×6 cm, and the second donor site was directly closed by suturing. Intraoperative end-to-end anastomosis was performed between the thoracodorsal arteries and veins of the latissimus dorsi myocutaneous flap and the arteries and veins of the primary recipient wound. The survival of latissimus dorsi myocutaneous flaps and local flaps were observed after surgery, and the appearance and function of the donor and recipient areas were observed during follow-up. Results: All the latissimus dorsi myocutaneous flaps and local flaps survived in the patients after surgery. Follow-up of 6-12 months showed that the latissimus dorsi myocutaneous flap was similar in color to the surrounding normal skin, with soft texture and good elasticity. The donor site of 20 patients repaired with bilobed latissimus dorsi myocutaneous flaps were only left with linear scars, among which 2 patients had hypertrophic scars and none had functional impairment. The donor site of 10 patients repaired with single-lobe latissimus dorsi myocutaneous flaps and donor site local flaps had good appearance, left with linear scar, irregular shape, but no local traction or dysfunction. Conclusions: When repairing a large soft tissue defect, the bilobed latissimus dorsi myocutaneous flap or the single-lobe latissimus dorsi myocutaneous flap combined with the local flap transfer in the donor site can be used after preoperative evaluation so that the donor site wound can be closed at one time while repairing the primary wound. The donor site has less scar, and both the recipient and donor sites have good appearance and function after surgery." @default.
