Objective To investigate and evaluate prevention and treatment of seroma by transposition of tissue flaps and Arista hemostatic powder after regional lymph node resection in patients with malignant tumors. Methods Twelve patients (6 males, 6 females; aged 31-81 years, with metastatic tumors underwent prevention and treatment of seroma with the tissue flaps and Arista hemostatic powder spray after regional lymph node resection. The metastatic tumors involved the axilla in 1 patient with breast carcinoma, the iliac and inguinal regions in 2 patients with carcinomas of theuterine cervix and the rectum, and the inguinal region in 9 patients, including4 patients with malignant fibrous histiocytoma（3 in the thigh, 1 in the leg）,2 patients with squamous carcinomas in the leg, 1 patient with synovial sarcomain the knee, 1 patient with epithelioid sarcoma in the leg, and 1 patient with malignant melanoma in the foot. As for the lymph node removal therapy. 1 patientunderwent axillary lymph node removal, 2 palients underwent lymph node removal in theiliac and inguinal regions, and 9 patients underwent lymph node removal inthe inguinal region. Meanwhile, of the 12 patients, 6 patients underwent transpostion of sartourius flaps with Arista hemostatic powder, 3 patients underwent transposition of the rectus abdominis myocutaneous flaps (including 2 patients treatedwith Arista spray befor the wound closure and 1 patient treated by transposition of local skin flaps with Arista spray used again),and 3 patients underwent only the suturing of the wounds combined with Arista. At the same time, of the 12 patients,only 4 patient underwent the transplantation of artificial blood vessels. Results The follow-up for 2-10 months after operation revealed that 10 patients, who had received the transposition of tissue flaps and the spray of Arista hemostatic powder, had the first intention of the incision heal with seroma cured. Nine patients were given a preventive use of Arista hemostaticpowder and therefore no seroma developed. The combined use of the transpositionof tissue flaps and Arista hemostatic powder spray achieved a success rate of 100% in the prevention or treatment of seroma. However, 1 patient developed microcirculation disturbance 24 hours after operation and underwent disarticulation of the hip; 1 patient developed pelvic cavity hydrops and died 10 months after operation. Conclusion The combined use of transposition of tissue flaps and Arista hemostatic powder spray can effectively prevent or treat seroma after regional lymph node removal in a patient with malignant tumor.
OBJECTIVE: To investigate the clinical effects of the microsurgical treatment for the skin-degloving injury of the whole hand or foot. METHODS: From March 1984 to October 2001, we treated 6 cases of skin-degloving injury of the whole hand and foot. In 2 cases of skin-degloving hands, one was treated with free great omentum transplantation plus skin graft, the other with pedical abdominal S-shaped skin flap as well as mid-thick skin graft. In 4 cases of skin-degloving injury of the foot, 2 cases was repaired with free latissimus dosi musculocutaneous flap, 1 case with distall-based lateral skin flap of the leg and 1 case with free tensor fasciae latae muscle flap. The flap size ranged from 7 cm x 9 cm to 22 cm x 15 cm. One case was operated on the emergency stage, the other 5 cases on the delayed stage. The delayed time ranged from 2 to 14 days with an average of 6.6 days. RESULTS: All the flaps survived. After 1-2 year follow-up, the appearance and function of the hand and the foot were good. CONCLUSION: Microsurgery technique in repairing skin-degloving injury of the whole hand and foot can achieve good results. The keys to success are thorough debridement of the recipient area, appropriate selection of the donor site, good vascular anastomosis and active postoperative rehabilitation.
OBJECTIVE: To investigate the method and clinical effect of temporal fascia flap, free forearm flap, free iliac bone transfer and immediate implant on reconstruction of maxillary defect. METHODS: From February 1999 to July 2002, 8 cases of maxillary defects due to excision of cancer were repaired immediately with temporal fascia flap, free forearm flap, free iliac bone transfer and implant. Out of 8 patients, there were 6 males and 2 females, aged 32-49 years, with a disease course of 3 months to 2 years. RESULTS: Free iliac bone and forearm flap survived in all 8 cases. Osseo-integration could be seen and the implants could be used for denture repair and chew function. After 6-12 months, X-ray examination showed iliac bone healing; facial shape and functional restoration were satisfactory. CONCLUSION: Temporal fascia flap, free forearm flap, free iliac bone transfer and immediate implant is an ideal method to repair maxillary defect immediately and reconstruct its function.
OBJECTIVE: To review the anatomy, etiology, therapy strategy of Achilles tendon injury and its related advances in recent years. METHODS: The related articles in recent years were extensively reviewed. RESULTS: There still were many arguments about the effect of corticosteroid on the treatment of tendon disease. Fluoqmnolone was found to be related with Achilles tendon injury. Acute rupture of Achilles tendon could be treated with open operation, percutaneous repair, or conservative therapy. For old rupture, many kinds of operations could be selected. CONCLUSION: The growth factors found in recent years provide us with new prospect for future treatment of Achilles tendon injury.
Objective To explore the clinical effect of latissimus dorsi musculocutaneous flap with a few muscle in repairing the soft tissue defect of lower limbs. Methods From June 2000 to December 2006, 8 patients with soft tissue defects of lower limbs were repaired with the latissimus dorsi musculocutaneous flaps. There were 6 males and 2 females, aged from 2569 years. The locations were heel in 3 cases, dorsum pedis in 2 cases, anticnemion in 2 cases, and the right leg (squamous carcinoma) in 1 case. The area of soft defect ranged from 10 cm×7 cm～18 cm×12 cm. The flap in size ranged from 15 cm×8 cm to 22 cm×15 cm. Results Of all the flaps,6 survived,1 had vascular necrosis 2 hours after operation and survived by skin grafts, 1 had delayed healing because of infection. The wound and donor site achieved primary healing. The followup for 3 to 12 months revealed that all the flaps had a good appearance. The function of donor site was as normal. Conclusion It is an ideal method to repair the softtissue defect of lower limbs with latissimus dorsi musculocutaneous flap.
Objective To review the current condition of growth factors and their application to clinical treatment of acute and chronic wounds. Methods Data from the literature and Medline were analyzed according to their different uses in acute and chronic wounds. Their potential side-effects were studied. Results All data showed that wound healing time in acute and chronic wounds was accelerated and wound healing quality was improved after treatment with growth factors. No sideeffect was observed. Conclusion The efficacy and safety of growth factors in improving wound healing were confirmed. However, some reconsideration aboutpotential problems of growth factors must be made to apply them clinically in the future.
From 1984 to 1994, 236 different types of traumatic defects of foot were repaired by microsurgical tissue grafting. They included simple cutaneous flap in 187 and composite flap in 49. Among the 236 different tissue flaps, vascularized flap was used in 97 and pedicled flap in 139. The 4 fore-foot and 6 heel defects were repaired by composite skeleted cutaneous grafts with scapula and vascularized febula respectively. After the follow-up from 1 to 10 years, all the grafted tissues were survived and healed well. The functions were satisfactory, and 186 patients had resumed their original works. The key to good function following repair was to maintaion the integrity of foot structures and the sensation of the sole and heel.
To summarize the effectiveness of the improv ed surgical techniques in fasciocutaneous flaps of the limbs. MethodsFrom February 1999 to December 2005, 58 patients (39 males, 19 females, aged 1068 years) underwent repairs of the skin defects with improved fasciaocu taneous flaps of the limbs. Twentyone patients had the skin defects in front of the tibial bone in the middle and lower parts, 12 patients had the skin defect s in the heels, 16 patients had the skin defects in the ankles, 3 patients had t he skin defects around the knees, 1 patient had a wide sacrococcygeal bedsore, and 5 patients had the skin defects in the wrists and hands. The wounds ranged in size from 5 cm×3 cm to 18 cm× 12 cm. According to the wound lo cations, the following flaps were selected: 4 cutaneous antebrachii medialis nerve and basilic vein fasciocutaneous flaps, 1 cutaneous antebrachii lateralis nerve and cephalic vein fasciocutaneous flap, 3 saphenous nerve and great saphenousvein fasciocutaneous flaps, 1 cutaneous nerve of thigh posterior fasciocutaneous flap, 32 reverse sural nerve and saphenous vein fasciocutaneous flaps, and 17 reverse saphenous nerve and great saphenous vein fasciocutaneous flaps. The dissected flaps ranged in size from 6 cm× 4 cm to 18 cm× 13 cm. The donor wounds underwent straight sutures in 39 patients, and the skin grafting (6 cm×3 cm to 13 cm× 6 cm) was performed on 19 patients after the donor wounds were closed. Results The wounds healed by first intention, and the flaps survived completely in 54 patients. The flaps developed partial necrosis in 4 patients. The followup for 120 months (average, 8 months) revealed that the flaps had a satisfactory appearance with a soft texture and the function was also satisfactory. Conclusion A fasciocutaneous flap of the limbs is an ideal flap for repairing defects in the skins and soft tissues of the limbs. The survival rate of the flap can be further improved by an improvement of the surgical techniques.
Objective?To investigate the surgical methods and clinical results of repairing soft tissue defects in the thumb with distally-based dorsal thumb neurocutaneous vascular flap.?Methods?From January 2006 to October 2007, 23 patients with soft tissue defect in the thumb were treated, including 20 males and 3 females aged 19-46 years old (average 27.5 years old). The defect was caused by crush injury in 1 case, electric planer accident in 6 cases, incised injury in 8 cases, and avulsion injury in 8 cases. The defect was located on the palmar aspect of the thumb distal phalanx in 3 cases, the dorsal-radial aspect of the thumb distal phalanx in 3 cases, and ulnar or dorsal aspect in 17 cases. The defect size ranged from 3.3 cm × 1.2 cm to 4.2 cm × 1.2 cm. Among them, 18 cases were complicated with distal 1/2 nail bed defect or injury. The time between injury and hospital admission was 1- 72 hours (average 22 hours). During operation, the defect was repaired with distally-based dorsal-radial neurovenocutaneous vascular flap of the thumb in 3 cases and distally-based dorsal-ulnar neurovenocutaneous vascular flap of the thumb in 20 cases. The size of those flaps was 4.0 cm × 1.6 cm-5.0 cm × 3.0 cm. The donor site underwent direct suture or split thickness skin graft repair.?Results?At 10 days after operation, 3 cases suffered from the epidermal necrosis in the distal part of the flap, 2 of them experienced the exfoliation of dark scab 14 days later and the flap survived, and the flap of the rest one survived after dressing change. The other flaps and the skin graft at the donor site all survived uneventfully. The wounds healed by first intention. All the patients were followed up for 10-16 months (average 12.6 months). The flaps were soft in texture and full in appearance. The two-point discrimination value 6 months after operation was 8-10 mm. At 12 months after operation, the growth of the residual fingernail was evident in 18 cases, including 4 cases of curved or hook fingernail. Active flexion and extension of the thumb were normal. The abduction of the first web space reached or surpassed 80 percent of the normal side in 20 cases and was below 80 percent of the normal side in 3 cases. The clinical outcomes were satisfactory in 11 cases, approximately satisfactory in 8 cases, and unsatisfactory in 4 cases according to self-designed evaluation system.?Conclusion?The operative method of repairing the soft tissue defects in the thumb with the distally-based dorsal thumb neurocutaneous vascular flap is simple, stable in anatomy, in line with the principle of proximity, and suitable for repairing thumb tip defect 3 cm in size. It can bring a good postoperative appearance of the thumb and little influence on the hand function.
In order to repair palpebral defects resulted from various causes, frozen tarsus of eyelid from newborn was used. From Jan. 1993 to Feb. 1995, the frozen preserved tarsus of eyelid from new-born was used to repair the palpebral defect in 10 cases. These defects were resulted following operation in traumatic defect in 5 cases, tramatic defect in 3 cases and congenital defect in 2 cases. After 3 month to 3 years follow-up, no refection reaction was found and no complication was occurred. The external appearance following repair was good. The overall successful rate was 100%. It was suggested that the frozen preserved tarsus from new-born was a safe and reliable material in the repair of palpebral defects.
