RESUMEN
To investigate the clinical efficacy of one-stage repairing the wounds after excision of soft tissue malignant tumor in lower limb with deep inferior epigastric perforator (DIEP) flaps. Methods From Au-gust, 2016 to July, 2018, 11 patients(8 males and 3 females; aged 35-76 years) with the soft tissue defects in the low-er limb underwent immediate reconstructive operations with DIEP flap after their tumor resection. The defects ranged in area from 11 cm×7 cm to 25 cm×10 cm after extended resection, including 5 cases of bone exposure. The DIEP flap area ranged from 11 cm×8 cm to 26 cm×18 cm.Among them, 9 cases were treated with free transplantation and 2 cases with pedicle transplantation.The donor sites were closed directly. The patients’ limb function, tumor recurrence and the healing of surgical incision had been followed-up. Results Eleven flaps survived and the donor sites healed directly. One flap had skin pigmentation due to postoperative vascular crisis, and the other flaps had satisfied texture and appearance. All patients were followed-up from 6 to 30 months. The lower limb movement was normal. All the donor sites had a good healing with no pain and abdominal complications. No tumor recurrence was observed during the followed-up period. Conclusion DIEP flap have many advantages, such as large cutting area, which is suitable for large-area wound repair after extended excision of soft tissue malignant tumor in lower limb. At the same time, the perforator vessel is constant and the caliber are thick, also the donor area is concealed and can be sutured directly.This kind of the technique for reconstruction of lower limb soft tissue defects after malignant tumor resection is well acceptable.

Objective To investigate the clinical efficacy of deep inferior epigastric perforator (DIEP) flap in the repair of soft tissue defects of the calf.Methods From January,2015 to January,2017,the DIEP flap was used to repair the soft tissue defect of calf in 11 patients,which were 7 males and 4 females,aged 23-62 years,with an average age of 42 years.Among them,there were 5 cases of anterior tibial soft tissue defect and 6 cases of posterior tibial soft tissue defect.The size of soft tissue defects ranged from 9.0 cm×5.0 cm to 32.0 cm×12.0 cm.The wounds were heavily polluted and debridement exploration combined VSD surgery in emergency.After 7 to 14 days,free deep inferior epigastric perforator flap was used to repaire.The flap was cut in the range of 10.0 cm×6.0 cm-34.0 cm×13.0 cm.Nine cases of abdominal donor sutured direct,and a small part of 2 cases to take thigh thick skin graft repair.Results All the flaps survived.In only 1 patient,the distal part of the flap was necrotic and healed after appropriate treatment.Eleven patients were followed-up for 3-18 months (average of 10 months).The shape of the flap was similar to that of the affected area.The texture was soft and not bloated.Conclusion The DIEP flap can provide reliable blood supply,large cutting area and flexible design.It can be used to repair soft tissue defect of calf and obtain satisfactory clinical results.
RESUMEN
Objective: To summarize the therapeutic effect of free deep inferior epigastric perforator (DIEP) flap and anterolateral thigh perforator (ALTP) flap in repairing skin and soft tissue defects in chest wall tumor resection.Methods: One old male patient with malignant fibrous histiocytoma of chest wall in China-Japan Union Hospital received operation,and the tumor was extendedly resected.The remaining chest wall defects were 10 cm×10 cm and 18 cm×14 cm,respectively.Free DIEP and ALTP flaps were used to repair the defects,and vascular pedicle was anastomosed with internal mammary artery and thoracic lateral artery,respectively.Results:After operation,the donor area was sutured directly,and two flaps survived with good appearance.The skin of ALTP flap was flatter than that of DIEP flap,and the texture and color of skin were close to those around chest wall.Conclusion:Free DIEP and ALTP flaps are ideal choice for repairing skin and soft tissue defects after resection in the male patient with chest wall tumor.
RESUMEN
Objective To evaluate satisfaction and complications of deep inferior epigastric perforator (DIEP) flaps breast reconstruction afer mastectomy in breast cancer patients.Methods The 26 consecutive breast cancer patients who underwent DIEP flap breast reconstruction were collected.General patient satisfaction and esthetic satisfaction with DIEP flap breast reconstruction were accessed using a study-specific questionnaire modified from the Michigan Breast Reconstruction Outcome Study.Results Flap success rate was 100％.The general satisfaction of DIEP breast reconstruction was 61.9％ (13/21),and the esthetic satisfaction was 66.7％ (14/21).Age (≤40 years old was 81.8％ [9/11],＞40 years old was 40.0％ [4/10],P=0.049) and previous abdominal wall surgery (no previous abdominal wall surgery was 75.0％ [12/16] and previous abdominal wall surgery was 20.0％ [1/5],P=0.027) were significant negative factors affecting general satisfaction;Body mass index (BMI ＜25 kg/m2 was 76.5％ [11/17],BMI 25-30 kg/m2 was 50.0％ [2/4],P=0.049) was a statistically significant factor associated with esthetic satisfaction.Four flaps presented venous congestion.One patient had fat necrosis and one had flap infection of the reconstructed breast.One patient had a decrease in abdominal rotational strength.Conclusions DIEP flap breast reconstruction will offer distinct advantages to patients,in terms of decreased donor-site morbidity and shorter recovery periods.
RESUMEN
Objective To investigate the effect of perforator identification before DIEP flap dissection for the patient with abdominal scar.Methods Preoperative multidetector-row computed tomography angiography was used to identify that the dominant perforators of the abdominal wall were not damaged completely.During the second stage breast reconstruction operation,the located dominant perforator and the DIEP flap were dissected.Results The dominant perforator located by MDCTA was identified with the exploration in operation.Follow-up for half a year,the flap survived well and the patient was satisfied with the appearance.Conclusion Abdominal scar was not the definite contraindication for DIEP flap.MDCTA provided a good quality evaluation of the perforator vessels.The located dominant perforator was dissected to confirm the blood supply of the DIEP flap.Identification of perforator can be used as a routine preoperative evaluation for patients with scar on donor site.
RESUMEN
Objective To study the method and effect of deep inferior epigastric perforator flap(DIEP)in repairing the large defects of lower limbs.Methods Eight cases,from July 2009 to November 2011,including 3 cases of plantar skin defects with bone exposure after foot injuries,three cases of plate exposure after tibia fracture surgery and 2 cases of heel repeated ulceration after skin graft,were repaired by deep inferior epigastric perforator flap.Results All deep inferior epigastric perforator flaps survived with good functions,except 1 case whose distal with poor blood supply and the flap survived after treatmenting,three cases of flap bloated with good appearances after second operation.Conclusion DIEP is a proper option for repair of large defects of lower limbs.It has the advantages of abundant blood supply,large flap area,abdomen can suturing without abdominal complications.
