Treatment of large defect of abdominal wall after tumors resection by transposition of tissue flaps with pedicle

Objective To report evaluat of division region of abdominal wall large defect after tumors resection and repair methods by tissue flaps with pedicle. Methods Form October 1992 to September 2001, 8 cases large abdominal wall defect after malignant tumors resection(10 × 10 cm-32 cm×32 cm) were reviewed. The defectcontributed:Ⅰ region, 2 cases; twin-Ⅱ region, 2; Ⅲ region, 2; Ⅰ and Ⅱ region of one side, 1 and total abdominal wall,one case, The tissue flaps of transposition included: gracilis myocutaneous flaps, 4; retus abdominal myocutaneous flaps, 2; external abdominal obligue musculo-fascia flaps, 2; latissimus dorsi muscle, tensor fasciae latae muscle and retus femoris muscle flaps each, 1. One patient used MycroMesh also. Results In the course of peroperation, the incisions of 8 cases healed in first time; total tissue flaps survived and all pateints started exercise left the bed in 3 weeks. All 8 patients were followed up average of 2 years and 5 months: the success rate of reconstruction

Lower rotating point nutrient vessels of sural nerve flap with distant pedicled repairing soft tissue defect of foot and ankle

To explore lower rotating potint nutrient vessels of sural nerve flap with distant pedicled repairing the soft tissue defect of foot and ankle.Methods Lay a foundation of anatomic studying from february 2003 to March 2004,using lower rotating point nutrient vessels of sural nerve flap with distant pedicled repairing the soft tissue defect of foot and ankle in 11 cases.Cause of injuring:traffic accident 7 cases,crushing 1 case,saw injury 1 case,skin cancer 1 case,chronic ulcer 1 case.Areas:foot heel 6 cases,shank lower section 2 cases,heel tendon 2 cases,the distant back of the foot 1 case.Using the flap axis point was 1～3 cm above the pin of the external heel,average 2 cm.The scope of the flap was 6.0 cm×8.0 cm～12.0 cm～18.0 cm.Results All sural nerve flaps were alive.Of them,2 cases have distant part necrosis,accompanying with subcutaneous tissue,1 case heels after change dressings,another heels after skin grafting.All case can walk as usual,the flap was wear-resisting and keenly feel.Conclusion Lower rotating point nutrient vessels of sural nerve flap,donner area was fine,available area was large,skin in the pink,easy grafting,without main blood vessel damage,survival rate high,it is a good donner area in repairing around heel,foot and shank lower section.7 refs,1 tab.
