Objective To review the progress in amputation technique of diabetic foot. Methods Recent l iterature concerning the amputation technique of diabetic foot was reviewed and analyzed. Results According to the different levels of the amputation, the diabetic foot’s amputation can be classified as major amputation and minor amputation, and differentkinds of methods can derive from these styles. Different factors should be considered when the style and method of amputation are chosen. Conclusion To the diabetic foot amputation, the general rule is to l imit the amputation level on the premise of the good cl inical effect. The health state, the region of the diabetic foot, the tissue perfusion, the susceptibil ity to infection in local tissue, and the abil ity of wound healing are important factors in selecting the styles and methods of diabetes-related amputations. Importance should be attached to the synthesis treatments of diabetes to prevent the higher level amputation.
ObjectiveTo overview the systematic reviews on efficacy and safety of hyperbaric oxygen in treatment of diabetic foot.MethodsCNKI, CBM, VIP, WanFang Data, The Cochrane Library, PubMed and EMbase databases were searched to collect systematic reviews or meta-analyses on the efficacy and safety of hyperbaric oxygen therapy for diabetic foot from inception to November 17th, 2019. Two researchers independently screened literature and extracted data. Then, AMSTAR 2 tool and PRISMA statement were used to evaluate the methodological quality and reporting quality of included systematic reviews, and the outcome indicators were comprehensively analyzed.ResultsA total of 10 systematic reviews were included. The results of AMSTAR 2 suggested that 6 systematic reviews were of extremely low quality, 3 of low quality, and 1 of high quality. The PRISMA score ranged from 16.5 to 27. The results of the included systematic reviews showed that hyperbaric oxygen therapy might be superior to other interventions in ulcer healing rate and large amputation rate without increasing the risk of adverse events. ConclusionsThe existing systematic reviews/meta-analysis evidence shows that hyperbaric oxygen therapy may have certain curative effect on diabetic foot, however, its methodology and report quality evaluation are insufficient.
ObjectiveTo explore the causes and management of the complications in diabetic foot treated with tibial transverse transport (TTT). MethodsBetween September 2015 and September 2019, 196 patients with diabetic foot were treated with TTT. There were 109 males and 87 females, with an average age of 67.6 years (range, 45-86 years). According to Wagner’s classification, there were 124 cases of grade 3, 62 cases of grade 4, and 10 cases of grade 5; the course of disease was 1-12 months, with an average of 2.6 months. All patients underwent the minimally invasive tibial osteotomy. The osteotomy site was the middle and lower tibia in 62 cases and the middle and upper tibia in 134 cases. The area of osteotomy was 20 cm2 in 83 cases and 7.5 cm2 in 113 cases. The osteotomy block was moved back and forth once in 92 cases and twice in 104 cases. The complications were recorded, including secondary fracture at tibial osteotomy, skin necrosis in osteotomy area, and pin tract infection. ResultsAmong 196 patients, 41 cases (20.9%) had complications. Nine cases (4.6%) had secondary fracture at tibial osteotomy, among which 6 cases (9.6%) of middle and lower segment osteotomies and 3 cases (2.2%) of middle and upper segment osteotomies. The incidence between the patients with different osteotomy sites was significant (χ2=5.354, P=0.021). The area of osteotomy was 20 cm2 in 5 cases (6.0%) and 7.5 cm2 in 4 cases (3.5%). There was no significant difference in the incidence between patients with different areas (χ2=0.457, P=0.499). Skin necrosis occurred in the osteotomy area in 12 cases (6.1%), all of which were moved back and forth once. There was a significant difference in the incidence between patients who were treated with transport once and twice (P=0.001). There were 18 cases (9.1%) with pin tract infection, including 12 cases (6.1%) with mild infection and 6 cases (3.0%) with severe infection. There was no significant difference in the incidence between the patients with mild and severe infections (P=0.107).ConclusionTTT is an effective method to treat diabetic foot, but there are complications such as secondary fracture at tibial osteotomy, skin necrosis in osteotomy area, and pin tract infection during transport. Preoperative evaluation of indication, standardization of osteotomy mode, size and position of osteotomy block, establishment of individualized removal plan, and strengthening of pin track nursing after operation can effectively reduce complications.
ObjectiveTo investigate the clinical therapeutic effect of silver ions dressing for patient with diabetic foot ulcers. MethodsAccording to the diagnostic and classification criteria of diabetes and diabetic foot of World Health Organization (WHO), outpatients and inpatients with diabetic foot ulcers admitted to the Department of Burns and Plastic Surgery of Dazhou Central Hospital from October 2013 to May 2015 were randomly divided into a silver ion dressing treatment group and a traditional dressing treatment group. The effective rate, time of occurrence of granulation tissue, wound healing time and wound area reduction ratio between the two groups were compared by using SPSS17.0 software. ResultsA total of 80 patients were included, of which 40 patients in each group. Compared with the control group, the total effective rate was higher (92.5% vs. 62.5%, P=0.001), the occurrence time of granulation tissue (6.4±0.72 vs. 10.8 ±1.9, P=0.000) and wound healing time (31.3±8.2 vs. 47.4±11.5, P=0.000) were shorter, and the wound area reduction ration was greater (46.3±7.6 vs. 32.6±6.1, P=0.000) in the silver ions dressing group with significant differences. ConclusionThe effects of silver-containing dressings is superior to Vaseline dressing in the treatment of diabetic foot ulcers.
ObjectiveTo explore the clinical efficacy of ultrasound debridement combined with autolytic debridement in the treatment of diabetic foot ulcers.MethodsA total of 60 diabetic foot ulcers patients who were diagnosed and treated in Jinshan Hospital of Fudan University from April 2019 to April 2020 were enrolled in the study and randomly divided into two groups, with 30 cases in each group. The trial group received autolytic cleansing combined with ultrasound debridement treatment, and the control group only received autolytic debridement treatment. The baseline conditions, wound treatment efficacy, number of dressing changes, length of hospital stay, treatment cost, wound healing time, wound shrinkage rate, and the time required for the wound to turn into 100% red granulation were compared between the two groups.ResultsThere was no statistically significant difference in gender, age, duration of diabetes or Wagner grade of diabetic foot between the two groups (P>0.05). The efficacy of wound healing in the trial group was better than that in the control group (Z=−2.146, P=0.032). The number of dressing changes [(11.76±2.23) vs. (17.34±4.43) times] and the length of stay [(18.03±3.73) vs. (25.43±4.43) d] in the trial group were lower than those in the control group, and the differences were statistically significant (P<0.05). The difference in treatment cost between the two groups was not statistically significant (P>0.05). The wound healing time of the trial group [(48.43±18.34) vs. (65.24±19.62) d], the wound shrinkage rate [(78.35±8.34)% vs. (56.53±6.54)%] and the time required for the wound to turn into 100% red granulation [(16.34±2.42) vs. (24.55±3.23) d] were better than those of the control group, and the differences were statistically significant (P<0.05). During the treatment process, no patient in the trial group had wound bleeding and had difficulty in stopping bleeding during ultrasonic debridement, and no patient had intolerable pain related to ultrasonic debridement. No patients in either group withdrew early.ConclusionsUltrasound debridement combined with autolytic debridement can effectively improve the curative effect of patients with diabetic foot ulcers and shorten the wound healing time. Therefore, it is worthy of promotion and application in the wound care of patients with diabetic foot ulcers.
ObjectiveTo evaluate the effectiveness of Ilizarov technique-based transverse tibial bone transport on the treatment of severe diabetic foot ulcer (Wagner grades 3 to 5) complicated with systemic inflammatory response syndrome (SIRS).MethodsBetween August 2014 and December 2017, 33 patients with severe diabetic foot and SIRS were treated with Ilizarov technique-based transverse tibial bone transport. There were 27 males and 6 females, with a mean age of 60.6 years (range, 34-79 years). All of them suffered from type 2 diabetes mellitus. The duration of diabetes was 1-28 years (mean, 10 years) and the duration of diabetic foot was 1-12 months (mean, 2.7 months). According to Wagner classification, there were 8 cases in grade 3, 23 cases in grade 4, and 2 cases in grade 5. The wound healing condition was observed after operation, and the limb salvage rate was calculated. The changes in body temperature, heart rate, respiratory rate, white blood cell count, erythrocyte sedimentation rate, and C-reactive protein concentration were assessed. The skin temperature of the dorsum of the foot was measured, and the visual analogue scale (VAS) score was used to evaluate the improvement of foot pain.ResultsAll 33 patients were followed up 3-30 months (mean, 14.1 months). All ulcers healed and the healing time was 3-12 months (mean, 5.3 months); the limb salvage rate was 100%. Postoperative body temperature, heart rate, respiratory rate, white blood cell count, erythrocyte sedimentation rate, and C-reactive protein concentration were significantly lower than those before operation (P<0.05). The skin temperature of the dorsum of the foot was (32.64±2.17)℃ at 1 month after operation, which was significantly improved when compared with preoperative value [(31.28±1.99)℃] (t=0.05, P=0.00); but there was no significant difference in skin temperature compared with healthy side [(32.46±2.10)℃] (t=2.04, P=0.41). The VAS score was 2.4±0.7 at 1 month after operation, which was significantly improved when compared with preoperative score (4.3±0.8) (t=3.10, P=0.00).ConclusionIlizarov technique-based transverse tibial bone transport is an effective way to treat severe diabetic foot complicated with SIRS. It can promote foot ulcer healing and avoid amputations.
To investigate the change of bacterial load appl ied with iodophors and rivanol of diabetic foot ulcers (DFUs), furthermore to evaluate the effect of both in removing superficial microbes of DFUs. Methods From March 2006 to March 2007, 30 patients were randomly divided into control group (group A, n=10), iodophor group (group B, n=10) and rivanol group (group C, n=10). There were 18 males and 12 females with an average age of 59.8 years (range 46-78 years). The wound size ranged from 3 cm × 2 cm to 15 cm × 10 cm. The disease course was 6 weeks to 6 months (mean 2.1months). Each wound was debrided and irrigated before process, then drug was compressed on the wound for 5 minutes, and irrigated again. The samples gained for three times, before, immediately and 24 hours after the process. Each sample was diluted before cultivation, the bacteria of wound were counted and compared among 3 groups. Results The cultures of specimens showed that the load decreased in every group, each cultured colony of specimen grew well, and there were no significant differences between 3 groups immediately after procedure (P gt; 0.05). There were significant differences between group B and groups A, C (P lt; 0.05), but there were no significant difference between group A and group C 24 hours after treatment (P gt; 0.05). Conclusion Both iodophors and rivanol could remove the bacteria on the surface of wound. Topical germicide could reduced bacterial load in the wound of diabetic foot, the role of steril izing and bacteriostasis of iodophors were better than that of rivanol.
