Prevalence Of Wound Complications Research Articles

Prevalence of wound complications following Mohs micrographic surgery (MMS): a cross-sectional study of 1000 patients undergoing MMS and wound repair in a UK teaching hospital.

BackgroundMohs micrographic surgery (MMS) for nonmelanoma skin cancer is often quoted as having an excellent safety profile.AimTo determine the complication rate of patients undergoing MMS in a large UK Mohs unit and subdivide complication rates into mild/intermediate and major, and to identify potential risk factors necessitating a clinical intervention.MethodsThis was a single‐centre, cross‐sectional study of 1000 consecutive cases of MMS performed with in‐house repair. Notes from the postsurgical dressing clinics were reviewed at Visit 1 (Days 7–14) and Visit 2 (approximately Week 6). Based upon the intervention required and effect on cosmetic/functional outcome, complications were classified as minor, intermediate or major. Logistic regression modelling was used to identify risk factors associated with a complication that needed a clinical intervention (i.e. intermediate or major).ResultsIn total, 1000 Mohs surgeries were performed on 803 patients, resulting in 1067 excisions. Complication rates in our cohort were low (minor 3.6%, intermediate 3.1% and major 0.8%) Potential risk factors for developing a complication included skin graft (unadjusted OR = 4.89, 95% CI 1.93–12.39; fully adjusted OR = 7.13, 95% CI 2.26–22.45) and patients undergoing surgery on the forehead (unadjusted OR = 3.32, 95% CI 0.95–11.58; fully adjusted OR = 5.34, 95% CI 1.40–20.42). Patients whose wounds were allowed to heal by secondary intention healing (6.8%) exhibited no complications.ConclusionWe advocate that patients should be informed during the consent procedure that less than 1 in every 100 patients (0.75%) undergoing MMS will have a serious adverse event (major complication) affecting their cosmetic or functional outcome.

The Prevalence of Wound Complications after Cardiac Surgery

Relevance. Infectious complications arising in the postoperative period (nosocomial infections) have an adverse effect on the results of high-tech interventions in a cardiac surgery clinic, worsening clinical results and being a significant article of medical expenses. Aims. To analyze modern literature data on the prevalence of nosocomial infections after high-tech cardiac surgery to identify factors that affect its variability. Conclusions. The prevalence of hospital Infectious complications after cardiac surgery remains high, ranging, according to various sources, from 0.9% to 35%. The deep form, accompanied by a significant mortality rate, is more common in the range from 0.4% to 5%, the incidence of superficial forms is much more variable, leaving from 1.5% to 30%. A prerequisite for controlling infection in a cardiac surgery hospital is thorough and adequate registration of such complications. Conducting a dynamic comparison of the prevalence of nosocomial infections in the process of epidemiological control requires the consistent use of unchanged methods of statistical analysis, constant criteria for determining a standard case and the use of up-to-date classifications. An important step in the study of the prevalence of nosocomial infections is to provide the obtained information to practicing physicians in order to maintain a high level of awareness of the effectiveness of treatment and prevention.

Percutaneous reduction and screw fixation for all types of intra-articular calcaneal fractures.

This study compares the outcomes of consecutive of patients with Sanders II and III and IV calcaneal fractures that were stabilized by either close reduction and internal fixation (CRIF) or open reduction and internal fixation (ORIF). Group I (N = 49) underwent close reduction internal fixation (CRIF). Group II (N = 39) underwent open reduction internal fixation (ORIF). The clinical outcomes included time to operation, operative duration, visual analog score (VAS), length of hospital stay, wound-related complications and AOFAS SF-36 score. Preoperative and postoperative radiographic measures also were compared. The duration of operation in the CRIF group was considerably shorter than in ORIF group (P = 0.0001). Postoperatively, at seventh day, the VAS in the CRIF group (4.2 ± 1.1) was meaningfully lower than those of the ORIF patients group (4.7 ± 1.2, P = 0.04). Totally, the prevalence of wound complications in CRIF group was significantly lower than in ORIF group. In final follow-up visit after one year, AOFAS scores and SF-36 scores between groups were comparable. Comparable radiographic measures were found in both groups. There was no significant difference between groups regarding preoperative radiographic measures (P > 0.05), while in postoperative imaging acceptable calcaneal fracture reduction was found in both groups. We believed that for treatment of various types of calcaneal fracture compared with ORIF the percutaneous reduction and screw fixation may lead to shorter hospital stay, decreased subtalar joint stiffness and earlier weight bearing along with much favorable patients' satisfaction.

Flap Failure and Wound Complications in Autologous Breast Reconstruction: A National Perspective.

There are many options for breast reconstruction following a mastectomy, and data on outcomes are greatly needed for both the patient and the care provider. This study aims to identify the prevalence and predictors of adverse outcomes in autologous breast reconstruction in order to better inform patients and surgeons when choosing a surgical technique. This study retrospectively reviewed the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) and identified each autologous breast reconstruction performed between 2005 and 2012. Of the 6855 autologous breast reconstructions, there were 2085 latissimus dorsi (LD) flap procedures, 2464 pedicled transverse rectus abdominis myocutaneous (TRAM) flap procedures, and 2306 free flap procedures that met the inclusion criteria. The prevalence of complications in each of the three procedures was calculated and compared using χ(2) analysis for binomial categorical variables. Univariate and multivariate logistic regression analyses identified independent risk factors for adverse outcomes in autologous reconstruction as a whole. The prevalence of general complications was 10.8% in LD flaps, 20.6% in TRAM flaps, and 26.1% in free flaps for autologous breast reconstruction (p < 0.001). The prevalence of wound complications was 4.3% in LD flaps, 8.1% in TRAM flaps, and 6.2% in free flaps for autologous breast reconstruction (p < 0.001). The prevalence of flap failure was 1.1 % in LD flaps, 2.7% in TRAM flaps, and 2.4% in free flaps for autologous breast reconstruction (p < 0.001). Multivariate regression analysis showed that obesity [odds ratio (OR) 1.495, p = 0.024], hypertension (OR 1.633, p = 0.008), recent surgery (OR 3.431, p < 0.001), and prolonged operative times (OR 1.944, p < 0.001) were independently associated with flap failure in autologous breast reconstruction procedures. When controlling for confounding variables, TRAM flaps were twice as likely (OR 2.279, p = 0.001) and free flaps were three times as likely (OR 3.172, p < 0.001) to experience flap failure when compared to LD flaps. Latissimus dorsi flaps are associated with the fewest short-term general complications and free flaps are associated with the most short-term general complications in autologous breast reconstruction. Free flaps are the most likely to experience flap failure, though there is no significant difference when compared to pedicled TRAM flaps. Free and TRAM flaps remain as the widely acceptable forms of breast reconstruction in the patient without many risk factors for flap failure or wound complications. The identified risk factors will aid in surgical planning and risk adjustment for both the patient and the care provider. Though many other factors will be taken into consideration with surgical planning of autologous breast reconstruction, the presence of these identified risk factors may encourage the use of a surgical technique associated with fewer adverse outcomes, like the LD flap.

Sirolimus as primary immunosuppression in liver transplantation is not associated with hepatic artery or wound complications

Sirolimus is a new immunosuppressive agent increasingly being used in liver transplant recipients. There is concern that sirolimus may be associated with wound complications and hepatic artery thrombosis (HAT). We have used sirolimus as primary immunosuppression in 170 liver transplant recipients and therefore reviewed our experience with wound complications and HAT in our cohort of patients. Records of all 170 patients administered sirolimus as primary immunosuppression and 180 historic controls were reviewed. Numbers of wound and hepatic artery complications were recorded, as well as the prevalence of obesity, reoperation, diabetes, and OKT3 use, all of which are risk factors for wound complications. The prevalence of wound complications was 12.4% in sirolimus-treated patients compared with 13.9% in historic controls (P = not significant [NS]). The prevalence of hepatic artery complications was 5.3% in sirolimus-treated patients compared with 8.3% in historic controls (P = NS). The prevalence of obesity and OKT3 administration was significantly lower in sirolimus-treated patients. Multivariate analysis failed to show an association between sirolimus therapy and hepatic artery or wound complications. The prevalence of wound and hepatic artery complications is not different in liver transplant recipients administered sirolimus as part of a primary immunosuppressive regimen compared with historic controls.

Endoscopic vs. Conventional Vein Harvesting:First Results with a New, Non-Disposable System

Most of the grafts used in coronary bypass surgery are still venous grafts. The preferred vein for bypass surgery is the long saphenous vein. Severe wound complications caused by saphenous vein harvesting occur in 1 % to 3 % of cases. Minor complications that do not need surgical revision occur in up to 43 % of cases. We developed an endoscopic harvesting technique using non-disposable instruments to reduce wound complications caused by vein harvesting. In a retrospective study, the occurrence of wound complications, haematoma, postoperative pain, ambulation, sensory disturbances and patient satisfaction were studied (n = 182). Patients who had either endoscopically harvested (n = 91) or conventionally harvested (n = 91) saphenous vein grafts were reviewed. Results were collected for 173 patients. The overall prevalence of wound complications was 18.7 %. The incidence of wound healing complications could be reduced significantly (p = 0.015) from 15.3 % to 3.4 % using the endoscopic technique. In the endoscopic group, postoperative ambulation was significantly (p = 0.002) easier, patient satisfaction was significantly (p = 0.007) higher, and postoperative leg swelling (p = 0.003) and haematoma (p = 0.004) could be reduced significantly. The occurrence of postoperative pain and sensory disturbances did not differ significantly. We conclude that the used endoscopic vein harvesting is a safe and cost effective method that can significantly reduce wound complications. An ongoing prospective study should establish our demonstrated data.

Does bilateral internal mammary artery grafting increase surgical risk?

The risk of bilateral internal mammary artery grafting was studied in three groups of patients who were computer matched for recognized risk factors: year of operation, age, gender, extent of coronary artery disease, left ventricular function, completeness of myocardial revascularization, and history of congestive heart failure. The patient groups differed in the fact that they received veins only, one internal mammary artery graft, or two internal mammary artery grafts. The operative mortality rates for these three groups were 1.8%, 0.3%, and 0.9%, respectively (no significant difference). Analysis of perioperative morbidity demonstrated no significant differences except for a slight increase in transfusion requirements in the group receiving two internal mammary artery grafts (p = 0.04). None of the patients with only vein grafts had wound complications. One patient in the group with one internal mammary artery graft had a wound complication (0.03%). Eight patients receiving two internal mammary artery grafts had wound complications (2.4%) (p = 0.002). The prevalence of wound complications in patients with diabetes mellitus was 5.7% and in those without diabetes mellitus, 0.3% (p = 0.01). The prevalence of wound complications in patients less than 60 years of age was 0.2%, in patients in their 60s, 1.6%, and in patients older than 70, 3.1% (p = 0.01). Multivariate logistic regression analysis identified diabetes mellitus and age and not bilateral internal mammary artery grafting as risk factors for wound complications. We conclude that bilateral internal mammary artery grafting does not increase surgical mortality and increases surgical morbidity by a slight increase in the mean transfusion requirement.
