In Brief Objective: To introduce the World Health Organization Surgical Safety Checklist into every operating room within a severely resource-limited hospital located in developing country and to measure its impact on surgical hazards complications. Background: The checklist has been shown reduce morbidity mortality, but ability successfully implement program hospital-wide lower income settings without basic resources is unknown. Methods: We conducted pre- versus postintervention study of...

Abstract Purpose We sought to use the NSQIP database determine national rate and predictors of free flap failure based upon sites types. Methods Free flaps were identified using 2005–2010 database. examined overall rates as well (head neck, extremities, trunk, breast) types (muscle, fascial, skin, bone, bowel flaps). Univariate multivariate analyses used failure. Results There 1,187 microvascular tissue transfers identified. The was 5.1%. Head neck had highest at 7.7%. Prolonged operative...

Little is known about the sustainability and long-term effect of surgical safety checklists when implemented in resource-limited settings. A previous study demonstrated marked, short-term a structured hospital-wide implementation checklist Moldova, lower-middle-income country, as have studies other low-resource settings.To assess reduction perioperative harm following introduction checklist-based quality improvement program setting to understand effects such programs.Twenty months after...

Background The deep inferior epigastric perforator (DIEP) flap is considered the gold standard for autologous breast reconstruction. Less commonly used abdominal flaps include superficial artery (SIEA) and circumflex iliac (SCIA) which are based on vasculature of wall. We sought to compare complication rates between DIEP system their associated risk factors. Methods A retrospective chart review 400 cancer patients undergoing abdominally-based free reconstruction with either a or from January...

The incidence of auricular deformities is believed to be ∼11.5 per 10,000 births, excluding children with microtia. Although not life-threatening, can cause undue distress for patients and their families. surgical procedures have traditionally been used reconstruct congenital deformities, ear molding has gaining acceptance as an efficacious, noninvasive alternative the treatment newborns deformations. We present successful correction bilateral Stahl's deformity in a newborn through...

Background: The modified five-item frailty index is a validated and effective tool for assessing risk in surgical candidates. authors sought to compare the predictive ability of established factors complications free flap breast reconstruction. Methods: 2012 2018 American College Surgeons National Surgical Quality Improvement Program database was queried reconstructive procedures. Univariate multivariate regression analysis models were used assess how commonly stratify (age, body mass index,...

Background There is an increasing trend toward bilateral breast reconstruction. Using the National Surgical Quality Improvement Program (NSQIP) database, we sought to understand association between unilateral and free flap reconstruction operative time failure. Methods We selected a cohort of patients undergoing using 2005 2010 NSQIP database. Cases were divided into Subgroup analyses performed dividing cases delayed immediate The effect patient characteristics including age, body mass index...

Purpose Our intent was to evaluate unplanned reoperations as a quality indicator for microvascular free tissue transfer (MFTT). Methods The National Surgical Quality Improvement Program database used identify MFTT cases from January 2012 December 2013. Multivariate logistic regression models were determine risk factors reoperations. Results We identified 2,244 cases. There 290 associated (12.92%). threefold increase in the rate of complications when patients underwent reoperation (58.28% vs...

The abdomen is the most common area from which tissue harvested for autologous breast reconstruction. We sought to examine national data determine differences in total hospital charges, length of stay (LOS), and early postoperative complications following pedicled transverse rectus abdominis myocutaneous flap (pTRAM), free TRAM (fTRAM), deep-inferior epigastric perforator (DIEP), superficial inferior artery (SIEA) flaps. 2009-2013 Nationwide Inpatient Sample Database was used identify...

Background: The accepted “one-size-fits-all” dose strategy for prophylactic enoxaparin may not optimize the medication’s risks and benefits after surgical procedures. authors hypothesized that weight-based administration might improve pharmacokinetics of when compared to fixed-dose administration. Methods: FIxed or Variable Enoxaparin (FIVE) trial was a randomized, double-blind pharmacokinetic clinical outcomes patients assigned randomly postoperative venous thromboembolism prophylaxis using...

Background Despite evidence supporting the safety of breast implants, some women associate their implants with adverse health effects and have called this syndrome “breast implant illness.” We sought to characterize illness symptoms report how removal affects symptoms.Methods An anonymous 20 question survey was administered Facebook group: “UTAH Breast Implant Illness” these attributed implants. Several questions allowed us evaluate affected women’s symptoms.Results Of 182 respondents, 97%...

Traditionally, has been performed subpectoral plane; however, there an emerging interest using ADM. Human (hADM), porcine (pADM), bovine (bADM) ADMs are available for use, but little known about benefits complication profiles each...
