OBJECTIVE: To explore an effective method to repair the abdominal wall defect. METHODS: From July 1996 to December 2000, 7 cases with abdominal wall defect were repaired by pedicle graft of intestine seromuscular layer and skin graft, among them, intestinal fistula caused by previous injury during operation in 4 cases, abdominal wall defect caused by infection after primary fistulization of colon tumor in 2 cases, abdominal wall invaded by intestinal tumor in 1 case. Exploratory laparotomy was performed under general anesthesia, the infective and edematous tissue around abdominal wall defect was gotten rid off, and the pathologic intestine was removed. A segment of intestine with mesentery was intercepted, and the intestine along the longitudinal axis offside mesentery was cutted, the mucous layer of intestine was scraped. The intestine seromuscular layer was sutured to the margin of abdominal wall defect, and grafted by intermediate split thickness skin. RESULTS: The abdominal wall wound in 6 cases were healed by first intention, but part of grafted skin was necrosed, and it was healed by second skin graft. No intestinal anastomotic leakage was observed in all cases. Followed up 1 to 2 years, there were no abdominal hernia or abdominal internal hernia. All the cases could normally defecate. The nutriture of all cases were improved remarkably. CONCLUSION: Pedicle graft of intestine seromuscular layer is a reliable method to repair abdominal wall defect with low regional tension, abundant blood supply and high successful rate.
Objective To evaluate a modified anterolateral thigh fascial flap designed for the treatment of the soft tissue defects in the forearmsand hands. Methods From September 2000 to December 2003, a modified anterolateral thigh fascial flap combined with the intermediate split thickness skin graft was applied to the treatment of 13 patients with the soft tissue defects in the forearms or the hands. There were 8 males and 5 females, aged 19-43 years (average, 27.6 years). Three patients had a mangled injury, 4 had a belt injury, and 6 had a crush injury; 6 patients had their tissue defects on the palm side of the forearm, 6 had their tissue defects on the dorsal side of thehand, and 1 had the defect in the index finger (dorsal side of the hand). The tissue defects ranged in size from 17.5 cm×7.7 cm to 4.6 cm×3.4 cm.In addition, 4 of the patients had an accompanying fracture in the forearm or the hand,and the remaining 9 had an extenor tendon injury. All the patients underwent emergency debridement and reposition with an internal fixation for the fracture; 3-5 days after the repair of the injured nerves, muscle tendons and blood vessels, the tissue defects were repaired with the anterolateral thigh fascial flap combined with the intermediate split thickness skin graft. Results No vascular crisis developed after operation. All the flaps survived except one flap that developed a parial skin necrosis (2.0 cm ×1.0 cm) in the hand, but the skin survived after another skingrafting. The follow-up for 3-12 months revealed that all the flaps and skin grafts had a good appearance with no contracture of the skin. According to the evaluation criteria for the upper limbs recommended by the Hand Society of Chinese Medical Association, 9 patients had an excellent result, 2 had a good result, 1 had a fair result, and 1 had a poor result, with a good/excellence rate of 85%. Conclusion The modified anterolateral thigh fascial flap combined with the skin graft is one of the best methods for the treatment of the soft tissue defects in the forearms and the hands. This method has advantages of no requirement for a further flap reconstruction, no skin scar or contracture in the future, easy management for the donor site, and less wound formation.
Objective To discuss the expression of α-melanocyte-stimulating hormone(α-MSH) mRNA in human medium thickness skin autografts and to investigatethe role of αMSH in hyperpigmented process of skin autografts. Methods The samples were from medium thickness skin autografts on neck of the patients after 1 year of surgery. The size of sample was about 1.0 cm×0.5 cm. RT-PCR technique was performed to detect the expression of α-MSH mRNA in medium thickness skinautografts and normal skin respectively. Masson-Fontana stain technique was performed to detect the contents of melanin in medium thickness skin autografts andnormal skin epidermis respectively. Results The expression ofα-MSH mRNA in medium thickness skin autografts was much ber than that in control normal skin, showing statistically significant difference (P<0.01). The expression of α-MSH/β2-microglobulin mRNA in normal skin of donor area was no statistically significant differences compared with normal skin around recipient area. The contents of melaninin medium thickness skin autografts epidermis obviously increased when compared with that of control normal skin. The expression of α-MSH mRNA was positive correlated with the contents of melanin in epidermis. Conclusion The above results indicate that the expression of α-MSH increases greater in medium thicknessskin autografts than in cortrol samples and was correlated with the pigmentation of skin autografts. Overexpression of α-MSH may play an important role in hyperpigmented process of skin autografts.
Objective To evaluate the clinical outcomes of free perforator flaps combined with skin graft for reconstruction of ankle and foot soft tissue defects. Methods Between June 2014 and October 2015, 20 cases of ankle and foot soft tissue defects were treated. There were 16 males and 4 females, aged from 19 to 61 years (mean, 43.3 years). Injury was caused by traffic accident in 7 cases, by crashing in 9 cases, and machine twist in 4 cases. The locations were the ankle in 6 cases, the heel in 3 cases, the dorsum pedis in 4 cases, and the plantar forefoot in 7 cases of avulsion injury after toes amputation. The size of wound ranged from 15 cm×10 cm to 27 cm×18 cm. The time from injury to treatment was from 11 to 52 days (mean, 27 days). The anterolateral thigh perforator flap was used in 11 cases, thoracodorsal antery perforator flap in 3 cases, medial sural artery perforator flap in 4 cases, deep inferior epigastric perforator flap in 1 case, and anteromedial thigh perforator flap in 1 case, including 5 chimeric perforator flaps, 5 polyfoliate perforator flaps, 3 flow-through perforator flaps, and 3 conjoined perforator flaps. The size of the perforator flap ranged from 10.0 cm×6.5 cm to 36.0 cm×8.0 cm, the size of skin graft from 5 cm×3 cm to 18 cm×12 cm. Results Venous crisis occurred in 2 flaps which survived after symptomatic treatment; 18 flaps survived successfully and skin grafting healed well. The follow-up time ranged 4-18 months (mean, 8.3 months). The flaps had good appearance, texture and color, without infection. The patients could walk normally and do daily activities. Only linear scars were observed at the donor sites. Conclusion Free perforator flap can be used to reconstruct defects in the ankle and foot, especially in the weight-bearing area of the plantar forefoot. A combination of free perforator flap and skin graft is ideal in reconstruction of great soft tissue defects in the ankle and foot.
【Abstract】 Objective To investigate the effects of different surgical methods in treating scalp mal ignanttumors. Methods From January 1995 to September 2004, 70 patients with scalp mal ignant tumor were treated with different surgical methods. There were 41 males and 29 females with an average age of 50.3 years (30-85 years). The course of disease ranged from 2 weeks to 3 years(mean 3.5 months). There were 31 cases of basal cell carcinoma, 24 cases of squamous carcinoma, 8 cases of melanocarcinoma, 4 cases of fibrous sarcoma, 2 cases of l iposarcoma, and 1 case of vasculosarcoma. Leision size ranged from 1.0 cm × 0.5 cm to 10.0 cm × 8.0 cm. Scalp defect ranged from 3 cm × 3 cm to 12 cm × 11 cm after clearing up the tumors. Defect was repaired with free skin transplantation in 51 cases, scalp flap in 12 cases, cervico-shoulder flap in 2 cases, trapizius myocutaneous flap in 3 cases, and radial artery retro-island flap in 2 cases. The flap sizes ranged from 5 cm × 4 cm to 18 cm × 12 cm. Results Of 70 cases, 67 skin flaps survived and incision healed by first intention; 2 flaps necrosed at distal part(lt; 1 cm) and healed by second intention after dressing change; 1 flap infected and was treated with symptomatic medication.All the donor sites healed by first intention. Fifty-five patients were followed up for 1 to 5 years and 5 cases had tumor recurrence. In patients receiving skin transplantation, 1 case of squamous carcinoma and 1 case of fibrous sarcoma relapsed after 1 year and 2.5 years respectively and were given radical resection and skin flap grafting; in patients receiving skin flap grafting, 1 case of vasculosarcoma and 1 case of squamous carcinoma relapsed after 6 months and 3 months respectively, and gave up treatment; 1 case of fibrous sarcoma relapsed after 2 years and was given radical resection and skin flap grafting. The other cases survived and had no tumor recurrence. Conclusion Scalp mal ignant tumors should be diagnosised and treated as early as possible. Clearing up completely by surgery is an effective method.
Eighteen cases of loss or obliteration of eye sockets from trauma or tumour were repaired with various methods: skin graft, postauricle flap with tempopostauricular blood vessel, forehead flap with temporal blood vessel and temporal flap with subcutaneous pedicle. Following 1 to 5 years follwup, the results were good and the improvement on outlooking was remarkable. The skin grafting was a simple and applicable method but it needed a longer time of blepharorrhaphy. The flap transfer was more complicated but suitable for the obliteration of the eye socket accompanied with depression deformity, but it usually would result in a secondary cicatricical malformation at the region around the eye. Thus, it was important to select a best operative method according to the specific condition.
