Objective To explore the method of the distal perforator-based gluteus maximus muscle V-Y flap to treat the sacral ulcer and to simplify the operative procedures.Methods From March 2002 to March 2005, 11 cases of sacral ulcer were repaired by distal perforatorbased gluteus maximus muscle flaps. The area of sacral ulcer ranged from 13 cm×11 cm to 18 cm×14 cm. Of 11 cases, 7 were female and 4 were male,whose age ranged from 21 to 69 years, and the disease course was 8 months to 3 years.A triangular flap was designed to create a V-Y advancement flap.The length of the base was made almost equal to the diameter of the defect.The apex of the tringle was located near the great trochanter. The medial part of the flap was elevated as a fasciocutaneous flap by dissecting the layer between the fascia and the muscle.The distal part ofthe flap was elevated by dissecting the layer between the gluteus maximus muscle and the fascia of the deeper muscle group.The flap was advanced to the defect. Results All the flaps survived. After a follow-up of 5 months to 3 years, the bilateral buttocks were symmetry and whose appearance was satisfactory. Except for 1 case dying of other disease, no recurrence of ulcer was observed.All the flaps survived. Conclusion The distal perforatorbased fasciocutaneous V-Y flap for treatment of sacral ulcers is a simple and reliable technique, which has several advantages over the conventional V-Y flap technique,such as excelent excursion,viable coverage with the fasciocutaneous component, high flap reliability, preservation of the contralateral buttock, and preservation of the gluteus maximus muscle function.

Methods Literatures about the surgical management of venous reflux disease in lower extremity were collected and reviewed. Results In patients with primary venous reflux disease,comprehensive surgical management of concomitant superficial,deep and perforating veins might greatly improve the clinical effect. Conclusion Comprehensive surgical management will be the direction of surgical management of primary venous reflux disease in lower extremity.
From Oct. 1993 to Dec. 1995, nineteen refractory cases with varicosis and chronic ulcer of lower limb were treated. The average age of these patients was sixty-eight, the disease history was more than 20 years. The size of the ulcer of the leg ranged from the minimum of 10 cm x 8 cm to the maximum of 30 cm x 15 cm. All of them had once received saphenectomy and split skin graft without ulcer healing before they were admitted in our department. Both venography and ultrasonography showed superficial venous valve incompetence. The following comprehensive treatment was adopted. Firstly, myoplasty around popliteal vein was done. Secondly, phlebexairesis and phleborrhaphy were done for the variciform veins through minor incision. Then through debridement of the ulcer was performed. Delayed split skin graft was exerted one week later. The result showed that all the cases were successful: the ulcer was healed and there was no recurrence of varicosis.
ObjectiveTo analyze the clinical effect of vacuum-assisted closure in treating venous ulcer. MethodsThirty seven patients including 21 males and 16 females with lower extremity venous ulcer treated in our hospital from January 2013 to January 2014 were included in our study. Based on random number table, the patients were divided into treatment group [n=19, (66.47±6.22) years old] and control group [n=18, (66.39±5.37) years old]. The treatment group received vacuum-assisted closure, while the control group underwent routine moist therapy. Wound healing and visual analogue pain scores were observed. Chi-square test and t-test were used for statistical analysis. ResultsWound healing rate was 84.2% in the treatment group and 55.6% in the control group, and the difference between the two groups was statistically significant (χ2=26.66, P<0.05). Wound healing time was (13.84±3.13) days in the treatment group and (27.35±1.73) days in the control group, and the difference was statistically significant (t=-7.498, P<0.01). Visual analogue pain scores in the treatment group was 3.53±0.51, and in the control group, it was 4.41±0.51, and the difference was statistically significant (t=-5.197, P<0.01). ConclusionVacuum-assisted closure can significantly improve wound healing and alleviate sufferings in the treatment of venous ulcer.
OBJECTIVE: To explore a method to repair severe radiation-induced ulcer and evaluate its clinical effects. METHODS: From August 1988 to December 1998, 12 cases of severe radiation-induced ulcer were treated by muscular or musculocutaneous flap transfer, which included 1 case of pectoralis major muscular flap, 3 cases of three-lobed transverse rectus abdominis musculocutaneous flap, 2 cases of latissimus dorsi musculocutaneous flap, 1 case of tensor fascia lata musculocutaneous flap, 1 case of longitudinal rectus abdominis musculocutaneous and tensor fascia lata musculocutaneous flap, 1 case of gastrocnemius muscular flap, 1 case of gluteus major musculocutaneous flap, huge filleted musculocutaneous flap from lower limbs in 1 case and from upper limbs in 1 cases. RESULTS: All the flaps survived. Primary healing occurred in 9 cases and secondary healing in 3 cases. The extensive multiple ulcers in 2 cases were repaired with filleted limb musculocutaneous flap, and patients were saved. And in other 3 cases, the chest wall defect as the result of radionecrosis were repaired with simultaneous breast reconstruction. CONCLUSION: Muscular or musculocutaneous flaps have abundant blood supply, they are ideal tissue to fill the cavity and repair the defect, especially in repairing severe radiation-induced ulcers.
ObjectiveTo investigate the clinical effectiveness of high-glucose insulin mixture on the local treatment of patients with grade Ⅱ and Ⅲ pressure ulcers. MethodsA total of 124 patients with grade Ⅱ and Ⅲ pressure ulcers treated between January 2011 and June 2012 were randomly divided into three groups: saline group (group A, n=41), high-glucose insulin mixture group (group B, n=41) and modern dressing group (group C, n=42). We observed and compared the treatment effects among the three groups using both measurements of traditional evaluation criteria and pressure ulcer scale for healing (PUSH) after a week of dressing. ResultsThe overall treatment effects among the three groups were significantly different (χ2=30.453, P<0.001). The results of pairwise comparisons was that the treatment effect was significantly different between group B or C and group A (P<0.01), but the treatment effect was not statistically different between group B and C (P>0.05). Subgroup analysis for patients with grade Ⅱ or Ⅲ pressure ulcers also came to the similar results. ConclusionBoth high-glucose insulin mixture and modern dressing have significant effects on patients with grade Ⅱ and Ⅲ pressure ulcers. However, the high-glucose insulin mixture costs less and is worthy of extensive promotion.
Objective To analyze the clinical characteristics of scar cancer ulcer wound of head and face, and to investigate its diagnosis and treatment. MethodsThe clinical data of 14 patients with head and facial scar cancer ulcer wounds who met the selection criteria and admitted between January 2021 and March 2022 were retrospectively analyzed. There were 8 males and 6 females. The age of onset ranged from 21 to 81 years with an average age of 61.6 years. The incubation period ranged from 1 month to 70 years, with a median of 4 years. Site of the disease included 7 cases of head, 6 cases of maxillofacial region, and 1 case of neck region. Injury factors included trauma in 5 cases, scratch in 5 cases, scalding in 2 cases, burn in 1 case, and needle puncture in 1 case. Pathological results showed squamous cell carcinoma in 9 cases, basal cell carcinoma in 3 cases, sebaceous adenocarcinoma in 1 case, papillary sweat duct cystadenoma combined with tubular apocrine sweat gland adenoma in 1 case. There was 1 case of simple extensive tumor resection, 1 case of extensive tumor resection and skin grafting repair, 7 cases of extensive tumor resection and local flap repair, and 5 cases of extensive tumor resection and free flap repair. ResultsAll the 14 patients were followed up 16-33 months (mean, 27.8 months). Two patients (14.29%) had scar cancer ulcer wound recurrence, of which 1 patient recurred at 2 years after 2 courses of postoperative chemotherapy, and was still alive after oral traditional Chinese medicine treatment. One patient relapsed at 1 year after operation and died after 2 courses of chemotherapy. One patient underwent extensive resection of the left eye and periocular tumor and the transfer and repair of the chimaeric muscle axial flap with the perforating branch of the descending branch of the left lateral circumflex femoral artery, but the incision healing was poor after operation, and healed well after anti-infection and debridement suture. The wounds of other patients with scar cancer ulcer did not recur, and the wounds healed well. ConclusionScar cancer ulcer wound of the head and face is common in the middle-aged and elderly male, and the main pathological type is squamous cell carcinoma. Local extensive resection, skin grafting, or flap transfer repair are the main treatment methods. Early active treatment of wounds after various injuries to avoid scar repeated rupture and infection is the foundamental prevention of scar cancer.
ObjectiveTo investigate the operation and effect of pressure ulcers group (PUG) on the procedure of clinical management of pressure ulcers. MethodsThe in-hospital patients with high-risk pressure ulcers and patients with pressure ulcers from outside of the hospital (n=145) before the founding of PUG in 2011 were regarded as group A, and patients in this group were treated by traditional therapies. After PUG was founded in our hospital in January 2012, 192 patients with high-risk pressure ulcers and from outside of the hospital in 2012 were considered as group B. In addition, group C contained 380 patients treated in 2013. Group B and C were both treated by PUG that developed a management system of pressure ulcers and took active measures to control and prevent pressure ulcers. PUG trained 30 clinical nurse supervisors, who were recommended from relevant clinical departments. The incidence of inevitable pressure ulcer of hospitalized patients, the cure rate of patients with pressure ulcers from outside of the hospital, pressure ulcer knowledge level of clinical nurse supervisors were comparatively analyzed between group A and B, and between group A and C, respectively. ResultsAfter the establishment of PUG, the incidence of inevitable pressure ulcer of hospitalized patients in group A, B, and C was 76.20%, 17.02%, and 14.61%, respectively. The cure rate of patients from outside of the hospital was 54.84%, 86.84%, and 87.97%, respectively. Differences between group A and B, and between group A and C both were significant (P<0.01). The pressure ulcer knowledge level of all nurse supervisors improved significantly (P<0.001). ConclusionThe establishment of PUG makes the clinical pressure ulcer management more scientific and objective. Furthermore, it can effectively reduce the incidence of pressure ulcers, and also improve the quality of medical care and ensure the safety of patients.
Objective To investigate the relationship among rats′ stress ulcer and gastric acid, prostaglandin (PGs) and adrenocorticotropin (ACTH) and to probe the pathogenesis, prophylaxis and therapy. Methods Rats′ stress ulcer model was made by cold water soaking and was properly treated with drugs such as hyoscine, dexamethasone, ranitidine and losec. The amount and pH of gastric juice, change of gastric mucosa and PGs and ACTH of blood were determined. Results After rats were fasted for 24 hours a little gastric juice was aspirated. After cold water soaking of rats gastric juice was increased with the pH decreased, there was gastric mucosal bleeding, blood PGs was decreased and ACTH was increased. These suggest that on stress gastric mucosa bleeding is related with decreased gastric juice pH, decreased PGs and increase ACTH.Conclusion To control stress ulcer, pH of gastric juice and amount of PGs should be increased. Losec can increase gastric juice pH, so losec is the first choice to control stress ulcer.
ObjectiveTo explore the effectiveness of the first-stage debridement and Ilizarov metatarsal bone lengthening in treatment of diabetic foot ulcer complicated with chronic osteomyelitis of metatarsal head.MethodsBetween January 2015 and October 2018, 8 cases (9 feet, 11 sites) of diabetic foot ulcer complicated with chronic osteomyelitis of metatarsal head were treated by first-stage debridement and Ilizarov metatarsal bone lengthening. There were 3 males (4 feet, 5 sites) and 5 females (5 feet, 6 sites), with an average age of 57.5 years (range, 44-65 years). According to diabetic foot Wagner grade, 6 cases (7 feet) were grade 3 and 2 cases (2 feet) were grade 4. The chronic osteomyelitis located at left foot in 4 cases, right foot in 3 cases, and bilateral feet in 1 case. The duration of chronic osteomyelitis was 1-5 years (mean, 3.1 years). The chronic osteomyelitis site was the 1st metatarsal head in 3 feet, the 3rd metatarsal head in 1 foot, the 4th metatarsal head in 1 foot, and the 5th metatarsal head in 6 feet. Two patients had chronic osteomyelitis at 2 sites on 1 foot. The length of lengthened metatarsal bone, lengthening time, and the time of wearing external fixation frame were recorded, and the external fixation frame index was calculated. The healing conditions of foot ulcer and lengthening bone segment were observed, the healing time was recorded, and the healing index of lengthening bone was calculated. The ankle function was evaluated according to the American Orthopedic Foot and Ankle Society (AOFAS) score criteria.ResultsAll patients were followed up 9-26 months with an average of 15.0 months. Except pin tract infection during the bone lengthening period, there was no complications such as skin necrosis and vascular or nerve injury occurred during treatment. The length of lengthened metatarsal bone was 12-35 mm with an average of 20.5 mm; the metatarsal bone lengthening time were 21-84 days with an average of 57.8 days. The average time of wearing external fixation frame was 14.6 weeks (range, 10.4-21.1 weeks) and the external fixation frame index was 54.3 days/cm (range, 42.9-59.2 days/cm). The ulcer wound healed with an average healing time of 30.5 days (range, 19-70 days) and no ulcer recurrence was observed during follow-up. Bone healing was obtained in all bone lengthening segments, and the average healing index was 42.5 days/cm (range, 37-51 days/cm). The average AOFAS score was 91.7 (range, 87-95); 5 feet were excellent and 4 feet were good. The excellent and good rate was 100%.ConclusionThe metatarsal bone lengthening under Ilizarov law of tension-stress after debridement can promote diabetic foot ulcers healing and reconstructing the length of metatarsal to retain the function of metatarsal load and avoid amputation. This is an effective method for the treatment of diabetic foot ulcer complicated with chronic osteomyelitis of metatarsal head.
