BackgroundEnthusiasm for anterior-based approaches for total hip arthroplasty (THA) continues to increase but there is concern for increased complications during the learning curve period associated. This study aimed to investigate if there was a difference in perioperative variables, intraoperative and immediate postoperative complications, or patient-reported outcomes when transitioning from a mini-posterior approach (mPA) to an anterior-based muscle-sparing (ABMS) approach for THA.MethodsRetrospective cohort study on the first 100 primary THA cases (n = 96 patients) of the senior author (August 2016 to August 2017) using the ABMS approach. These cases were compared to primary THA cases done the year prior (July 2015 to July 2016, n = 91 cases in 89 patients) using an mPA. Data were extracted and analyzed via gamma regression with robust standard errors and using generalized estimating equation regression.ResultsWe found no difference in the estimated blood loss (P = .452) and surgical time (P = .564) between the cohorts. The ABMS cases had a slightly shorter length of stay (P = .001) with an adjusted mean length of stay of 1.53 days (95% confidence interval 1.4-1.6) compared to 1.85 days (95% confidence interval 1.8-1.9) in the mPA cases. There was no difference in the frequency of immediate postoperative complications (all, P > .05). There was no difference in the adjusted mean change in patient-reported outcomes (all P > .05). In the ABMS group, there was no difference in surgical time or physical function computerized adaptive test between the first 20 cases (reference) and each subsequent group of 20 cases (all P > .05).ConclusionThis study demonstrates no associated learning curve for an experienced senior surgeon when switching routine THA approach from mPA to ABMS. We advise careful interpretation of our results, as they may not apply to all surgeons and practices.Level of EvidenceLevel III Therapeutic Study: retrospective comparative study. 相似文献
In the Netherlands, safe and sufficient drinking water is provided to the general population by ten drinking water companies. To guarantee safe drinking water the World Health Organization (WHO) developed a Water Safety Plan (WSP), a Risk Assessment and a Risk Management (RA/RM) framework. The objective of the study was to identify legally required RA approaches, to document application of RA/RM activities at Dutch drinking water companies and to determine to what extent these RA/RM activities as a whole cover all the elements of the WHO WSP approach. This study could be of interest to both managers of large water utilities and decision makers.The assessment was performed by means of a policy review and interviews with two to four staff members involved in RA/RM from all ten Dutch drinking water companies combined with a joint workshop. The drinking water companies are well aware of the potential hazards and risks that can influence the drinking water quality. To guarantee the supply of safe and sufficient drinking water, the Dutch drinking water sector uses six different legally required RA/RM approaches. This study shows that by using the six legally required RA/RM approaches, all WSP steps are covered. WSP entails a generic risk assessment for identifying all hazards and hazardous events from source to tap, whereas the six legally required RA/RM each focus on specific risks at an advanced level. Each risk assessment provides information on specific hazards and hazardous events covering a part of the water supply chain. These legal requirements are complemented with additional RA/RM activities at sector and water company level such as codes of practices and standard operating procedures. The outcomes of all RA/RM approaches combined provide information from source to tap. When using multiple RA/RM approaches, it is crucial to share and combine information derived from the different activities. 相似文献
BackgroundThe third most common bariatric surgery is revisional bariatric surgery. The American College of Surgeons tracks outcomes using the Metabolic and Bariatric Surgery Accreditation Quality Initiative Program database. We used this database to examine trends in revisional bariatric surgery.ObjectiveTo evaluate how trends in bariatric revisional surgery have changed in recent years.SettingUniversity Hospital, United States.MethodsThe Metabolic and Bariatric Surgery Accreditation Quality Initiative Program database for 2015 to 2017 was examined for revisions of bariatric surgery. Patients who underwent revisional bariatric surgery were identified by the primary Current Procedural Terminology code, the REVCONV and PREVIOUS_SURGERY field as well as secondary Current Procedural Terminology codes. There is no exact code for sleeve gastrectomy (SG) to laparoscopic Roux-en-Y gastric bypass (LRYGB), so we used 43644 (GB)+REVCONV+PREVIOUS_SURGERY for this.ResultsFor the years 2015 to 2017 there were 57,683 revisions/conversions of 528,081 patients. The number of revisions increased over the study period by 5213 cases. The most common revision was laparoscopic adjustable gastric band (LAGB) to SG with 15,433 cases and the second was LAGB to LRYGB with 10,485 cases. There were 14,715 LAGB removals. It is more difficult to track SG to LRYGB but there were 8491 unlisted cases, which may have been sleeve to bypass.ConclusionLAGBs are being taken out or converted, and this group makes up the largest portion of revisions and conversions. It is difficult to track SG to LRYGB, but the number of unlisted cases continues to climb. This will likely surpass LAGB conversions with time. The Metabolic and Bariatric Surgery Accreditation Quality Initiative Program should be modified to capture revisions/conversions of SG. 相似文献
Introduction: Surgery in patients with head and neck cancers is frequently complicated by multiple stages of procedure that includes significant surgical removal of all or part of an organ with cancer, tissue reconstruction, and extensive neck dissection. Postoperative wound infections, termed ‘surgical site infections’ (SSIs) are a significant impediment to head-and-neck cancer surgery and recovery, and need to be addressed.
Areas covered: Approximately 10–45% of patients undergoing head-and-neck cancers surgery develop SSIs. SSIs can lead to delayed wound healing, increased morbidity and mortality as well as costs. Consequently, SSIs need to be avoided where possible, as even the surgery itself impacts on patients’ subsequent activities and their quality of life, which is exacerbated by SSIs. Several risk factors for SSIs need to be considered to reduce future rates, and care is also needed in the selection and duration of antibiotic prophylaxis.
Expert commentary: Head and neck surgeons should give personalized care especially to patients at high risk of SSIs. Such patients include those who have had chemoradiotherapy and need reconstructive surgery, and patients from lower and middle-income countries and from poorer communities in high income countries, who often have high levels of co-morbidity because of resource constraints. 相似文献
Primary surgical prevention in the form of risk-reducing salpingo-oophorectomy (RRSO) is the most effective option and the gold standard for ovarian cancer (OC) risk-reduction, particularly given the absence of an effective national OC screening programme. However, premenopausal RRSO leads to premature surgical menopause with detrimental long-term health sequelae particularly in women who do not/are unable to take hormone replacement therapy (HRT). HRT uptake in women undergoing pre-menopausal oophorectomy appears low and is dependent on informed counselling, the safety of HRT and efficacy in mitigating the health sequelae of premature menopause. Acceptance of a central role for the fallopian tube in OC etiopathogenesis, coupled with the detrimental consequences of premature menopause, has led to the attractive proposal of early-salpingectomy with delayed oophorectomy as an alternative OC surgical prevention strategy in premenopausal women who have completed childbearing but decline or wish to delay RRSO. The successful implementation of risk reducing surgery for OC prevention depends on the acceptability of surgery to both, recipients (e.g. BRCA1/BRCA2 carriers) and intervention deliverers (healthcare professionals/researchers). Acceptability is also informed by an understanding of health outcomes following risk reducing surgery and the safety of HRT. It is therefore vital to understand the effects of surgery on important health outcomes such as cardiovascular health, neurological function and bone health. We present a comprehensive review of acceptability, the selected health outcomes mentioned above and HRT safety following risk reducing surgery. 相似文献
