Immediate repair of major abdominal wall defect after extensive tumor excision in patients with abdominal wall neoplasm: a retrospective review of 27 cases [corrected].

Background: The treatment of abdominal wall neoplasm continues to present a challenging problem because it is not easy to repair the giant defect which is resulted from extensive tumor excision. Some techniques and materials have been reported, but most report a certain technique or material for abdominal wall reconstruction. Therefore, we retrospectively reviewed the treatment of such patients in our department and assessed the reconstruction algorithm in such a situation.

[Anatomy and clinical application of posterior calf fasciocutaneous flap].

Objective: To investigate the blood supply and the clinical application of the posterior calf fasciocutaneous flap for repairing the frontal defect of knee joint.

Methods: Based on the article review and the anatomical study of the posterior calf in 8 cadavers (16 sides), 10 cases with frontal defects of knee joints were repaired with island fasciocutaneous flaps which had pedicles of lateral superficial sural artery and the lateral sural nerve.

Results: The anatomical study showed there were three systems of superficial sural blood supply- medial, middle and lateral systems.

Reconstruction of the abdominal wall by using a combination of the human acellular dermal matrix implant and an interpositional omentum flap after extensive tumor resection in patients with abdominal wall neoplasm: a preliminary result.

Aim: To present our trial using a combination of the human acellular dermal matrix (HADM) implant and an interpositional omentum flap to repair giant abdominal wall defects after extensive tumor resection.

Methods: Between February and October of 2007, three patients with giant defects of the abdominal wall after extensive tumor resection underwent reconstruction with a combination of HADM and omentum flap. Postoperative morbidities and signs of herniation were monitored.

[Clinical analysis of complications of polyacrylamide hydrogel injection for augmentation mammoplasty in 118 cases].

Objective: To analyze the clinical manifestations and explore suitable treatments for the complications induced by polyacrylamide hydrogel(PAHG) injection for augmentation mammoplasty.

Methods: The symptoms, physical signs and treatments of the 118 cases were analyzed and summarized.

Results: The complications included in nodule formation (54.

[Microvascular nasal repair using a reversed superficial temporal artery auricular flap.].

Objective: A reversed superficial temporal artery auricular flap was presented to explore a new method for reconstructing the defects of the distal nose by microsurgical techniques.

Methods: A reversed superficial temporal artery auricular flap had been used on fifteen patients with nasal defects, including thirteen patients with alar defects and two patients with nasal tip defects. The reversed superficial temporal vessels of the flap were anastomosed with the recipient facial vessels.

[Microsurgical reconstruction of the nasal subunit defects].

Objective: The nose is composed of several delicate subunits, some of which are difficult to reconstruct if they have been injured. The paper presents the microsurgical technique to repair the nasal subunit defects with the free combined preauricular and auricular flap which well match the nasal tissues in texture, contour and color.

Methods: The nasal subunit defects were repaired with the combined preauricular and auricular flap which were vascularized by the superficial temporal vascular system.

[Construction and clinical application of tissue engineered epidermal membrane].

Objective: To Construct tissue engineered epidermal membrane for promoting healing of clinical skin graft donor site wound.

Methods: Epidermal cells /Chitosan-Gelatin (CG) membrane was constructed with cultured human epidermal cells(EC) and CG membrane, at the donor site of split skin graft, the wound was divided into three groups: the control group was covered with CG membrane without KC, KC/CG membrane was grafted on the treatment part of the wound area, and blank group was covered with traditional vaseline gauze. The engineered epidermal membrane and its effect on wound were evaluated with gross observation, HE, immunohistochemistry, collagen type I/III ratio by picrosirius polarization method and RT - PCR test at various time points before and after operation.

[Nasal alar reconstruction with a vascularized free auricular composite flap].

Objective: The plastic surgeons prefer to reconstruct nasal alar with free auricular composite flap because it well matches nasal tissue in contour, texture and color. However, the size of the free composite flap should be less than 1. 0 cm x 1.

[Effects of hVEGF cDNA on random skin flap via a replication-deficient adenovirus vector].

Objective: The purpose of this study was to determine the effects of local delivery of vascular endothelial growth factor( VEGF) transferred with adenovirus-mediated gene on the survival of ischemic random skin flap in rats.

Methods: The animals were divided into three groups randomly (n = 10) . A 2 cm x 8 cm dorsal skin flap was designed with the pedicle at the level of the iliac crest.

[Application and review of the reversed posterior interosseous artery flap in 78 clinical cases].

Objective: To assess and review the indications and methods of the reversed posterior interosseous artery flap for repairing soft tissue defects of the hand.

Methods: In the series, three types of flaps were utilized including the reversed posterior interosseous artery flap, the expanded reversed posterior interosseous artery flap and the reversed posterior interosseous artery conjoint flap. 78 clinical cases were treated with this method, in which 12 cases used the expanded reversed posterior interosseous artery flap and 10 cases used the reversed posterior interosseous artery conjoint flap.

[Intra-uterine model of cleft lip and scarless wound healing of fetal rats].

Objective: To properly evaluate the benefits of in utero repair of cleft lip, an animal model of cleft lip was developed and the fetal scarless wound healing was observed in SD rat fetus.

Methods: Through a maternal celiotomy and hysterotomy, twenty excisional cleft was created in the upper lip of rat fetus. Another group of 20 rat fetus were given full-thickness incisional wounds in the upper lips.

[Experience for reconstruction of defects of abdominal wall with Gore-tex].

Objective: To evaluate the outcome of prevention of abdominal hernia in reconstruction of defect of abdominal wall with Gore-tex clinically.

Methods: Six cases of the large defects of abdominal wall were repaired with Gore-tex after surgical removal of abdominal wall tumor.

Results: The reconstructed cases were followed up six months to three years and there was no postoperative complication.

Effect of adenovirus-mediated gene transfection of vascular endothelial growth factor on survival of random flaps in rats.

Objective: To evaluate the effect of local application of vascular endothelial growth factor (VEGF) via adenovirus-mediated gene transfer on survival of full thickness flaps selected randomly in rats.

Methods: Thirty Sprague-Dawley rats weighing 480-520 g were used in this study. A dorsal flap (8 cm x 2 cm) in full thickness with the pedicle located at the level of the iliac crest was designed.
