Project description:IntroductionEpidural analgesia is currently considered the gold standard in postoperative pain management for the minimally invasive Nuss procedure for pectus excavatum. Alternative analgesic strategies (eg, patient-controlled analgesia and paravertebral nerve block) fail in accomplishing adequate prolonged pain management. Furthermore, the continuous use of opioids, often prescribed in addition to all pain management strategies, comes with side effects. Intercostal nerve cryoablation seems a promising novel technique. Hence, the primary objective of this study is to determine the impact of intercostal nerve cryoablation on postoperative length of hospital stay compared with standard pain management of young pectus excavatum patients treated with the minimally invasive Nuss procedure.Methods and analysisThis study protocol is designed for a single centre, prospective, unblinded, randomised clinical trial. Intercostal nerve cryoablation will be compared with thoracic epidural analgesia in 50 young pectus excavatum patients (ie, 12-24 years of age) treated with the minimally invasive Nuss procedure. Block randomisation, including stratification based on age (12-16 years and 17-24 years) and sex, with an allocation ratio of 1:1 will be performed.Postoperative length of hospital stay will be recorded as the primary outcome. Secondary outcomes include (1) pain intensity, (2) operative time, (3) opioid usage, (4) complications, including neuropathic pain, (5) creatine kinase activity, (6) intensive care unit admissions, (7) readmissions, (8) postoperative mobility, (9) health-related quality of life, (10) days to return to work/school, (11) number of postoperative outpatient visits and (12) hospital costs.Ethics and disseminationThis protocol has been approved by the local Medical Ethics Review Committee, METC Zuyderland and Zuyd University of Applied Sciences. Participation in this study will be voluntary and informed consent will be obtained. Regardless of the outcome, the results will be disseminated through a peer-reviewed international medical journal.Trial registration numberNCT05731973.

Project description:Surgery to repair pectus excavatum (PE) is often associated with severe postoperative pain, which can impact the length of hospital stay (LOS). While thoracic epidural analgesia (TEA) has traditionally been used for pain management in PE, its placement can sometimes result in severe neurological complications. Recently, paravertebral block (PVB) and erector spinae plane block (ESPB) have been recommended for many other chest and abdominal surgeries. However, due to the more severe and prolonged pain associated with PE repair, it is still unclear whether continuous administration of these blocks is as effective as TEA. Therefore, we conducted this systematic review and meta-analysis to demonstrate the equivalence of continuous PVB and ESPB to TEA.

Project description:BackgroundMinimally invasive repair of pectus excavatum (MIRPE) is a popular method for surgical correction of PE, and its impact on quality of life is a growing area of interest. We performed a systematic review and meta-analysis to evaluate the impact of MIRPE on the quality of life of patients.MethodsThis study was registered with PROSPERO under reference number CRD42020222061. A literature search of PubMed, Cochrane Library, EMBASE and Scopus was conducted from the date of inception till November 23, 2020. We included studies which administered one or more questionnaires on patients up to 60 years old, parents or both, to assess the quality of life before and after MIRPE. Studies not written in English, abstracts, articles without primary data, reviews and studies which combined data on PE and other deformities were excluded. Risk of bias was assessed using the Risk of Bias in Non-randomised Studies of Interventions and the Cochrane risk of bias tool. A random-effects meta-analysis was performed to obtain mean differences for key themes of quality of life before and after MIRPE. Responses from the same questionnaires, as well as common themes across different questionnaires, were compared.ResultsOf the 20 studies identified for systematic review, 7 studies that reported the responses of 478 patients were included in the meta-analysis. Patients who underwent MIRPE experienced an increased self-esteem [standardized mean difference (SMD): 1.38, 95% confidence interval (CI): 0.95 to 1.81, P<0.00001] and a smaller degree of chest interference with their social activities (SMD: 0.84, 95% CI: 0.60 to 1.08, P<0.00001). These findings were consistent even after the implanted bar was removed.ConclusionsMIRPE may be associated with a better quality of life for patients with PE as self-esteem and extent of chest interference with social activities are improved after the procedure. The key limitations of this study are the lack of high-quality evidence due to paucity of randomized trials, and the significant heterogeneity in reported outcomes due to variations in the questionnaires and timepoints of administration.

Project description:BackgroundPectus excavatum, the most common chest wall deformity, is frequently treated with Nuss procedure. Here we will describe non-invasive procedure and analyze the variables associated vacuum bell therapy for patients with pectus excavatum.MethodsRetrospective case-control study in a single center between July 2018 and February 2022, including patients with pectus excavatum treated with vacuum bell. Follow-up was continued to September 2022. The Haller index and Correction index was calculated before and after treatment to analysis the effectiveness of vacuum bell therapy.ResultsThere were 98 patients enrolled in the treatment group, with 72 available for analysis, and the follow-up period ranged from 1.1 to 4.4 years (mean 3.3 years). When analyzing with the Haller Index, 18 patients (25.0%) showed excellent correction, 13 patients (18.1%) achieved good correction, and 4 patients (5.6%) had fair correction. The remaining patients had a poor outcome. Characteristics predicting a non-poor prognosis included initial age ≤ 11 years (OR = 3.94, p = 0.013) and patients with use over 24 consecutive months (OR = 3.95, p = 0.013). A total of 9 patients (12.5%) achieved a CI reduction below 10. Patients who started vacuum bell therapy at age > 11 had significantly less change compared to those who started at age ≤ 11 (P < 0.05). Complications included chest pain (5.6%), swollen skin (6.9%), chest tightness (1.4%) and erythema (15.3%).ConclusionsA certain percentage of patients with pectus excavatum can achieve excellent correction when treated with pectus excavatum therapy. Variables predicting better outcome including initial age ≤ 11 years both in HI and CI and vacuum bell use over 24 consecutive months in HI. In summary, pectus excavatum is an emerging non-invasive therapy for pectus excavatum and will be widely performed in a certain group of patients.

Project description:IntroductionPrevious studies demonstrated a release of toxic metals, e.g. nickel and chromium, from stainless steel bars used for minimally invasive repair of pectus excavatum (MIRPE). In the present study, we investigated the impact of titanium nitride coating on the metal release and exposure of MIRPE patients.Material and methodsWe analyzed the courses of nickel and chromium levels in blood, urine and local tissue in patients undergoing MIRPE with a titanium nitride coated pectus bar between 03/2017 and 10/2018. Sample collection was scheduled prior to MIRPE, at defined postoperative time points and at bar removal. Additionally, we evaluated irritative symptoms. Results were compared to a control group who received uncoated stainless steel bars in a previous time period (03/2015-02/2017).Results12 patients received coated pectus bars (mean age 15.7 years). The control group included 28 patients. After implantation of a titanium nitride coated bar, significant increase in systemic nickel and chromium levels after one, two and three years was noted. In an interim analysis one year after MIRPE, we observed patients with coated bars to have significantly elevated trace metal values compared to the control group. This elevation persisted throughout the observation period. Tissue metal values were also significantly increased. Irritative symptoms occurred significantly more often in study patients compared to controls (50.0% vs. 14.3%).ConclusionsCoating of pectus bars with titanium nitride failed to reduce metal contamination after MIRPE. Instead, it resulted in a significant increase of trace metal levels after MIRPE, compared to patients with stainless steel bars, which may be explained by wear of the coating and inter-component mobilization processes.

Project description:BackgroundPostoperative pain control after the minimally invasive repair of pectus excavatum (MIRPE) is essential, but there is a controversy about a better analgesic method between epidural and intravenous (IV) analgesia. This systematic review and meta-analysis aimed to compare the effect of epidural versus IV analgesia following MIRPE.MethodsWe searched PubMed, MEDLINE, EMBASE, Cochrane Central Register, and ClinicalTrials.gov for randomized controlled trials (RCTs) dated up to 31st May 2021. The primary outcome was the area under the curve (AUC) of the weighted mean visual analog scale (VAS) after MIRPE. The secondary outcomes were postoperative nausea, operation time, total operating room time, and postoperative length of hospital stay.ResultsFour RCTs involving 243 patients were finally included in this meta-analysis. The AUC of the weighted mean VAS was 343.62 in the epidural group and 375.24 in the IV group. The epidural group showed lower VAS than the IV group at 12 to 48 h after the surgery. Postoperative nausea, operation time and length of hospital stay was not different between two groups. The epidural group had a significantly longer total operating room time due to epidural catheter insertion time.ConclusionsEpidural analgesia after the MIRPE had a better analgesic effect than IV analgesia. However, IV analgesia may also be a viable option, and physicians should wisely choose analgesic modalities after MIRPE.

Project description:BackgroundNational data is limited on pectus excavatum, the most common chest wall deformity which is often repaired using the Ravitch and Nuss procedures. The purpose of the study was to describe demographics and outcomes of adult patients who underwent surgical repair of pectus excavatum via open and minimally invasive thoracoscopic methods.MethodsA retrospective analysis of the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database from 2015 to 2018 was performed, capturing patients 18 years or older with pectus excavatum as the postoperative diagnosis. Patients were placed into two groups of minimally invasive (Nuss) and open (Ravitch) repair procedure code. Baseline characteristics and postoperative outcomes were analyzed.ResultsA total of 168 adult patients were captured. Most of these patients were white (84.52%) male (69.64%) and 26 years old on average. Median operative time was longer in the open repair group [250 (IQR, 173-308) versus 122 (IQR, 94-160) minutes, P<0.0001]. Median length of stay was five days (IQR, 4-6) in the open group and three days (IQR, 2-4) in the minimally invasive group (P=0.2873).ConclusionsComplications after repair of pectus excavatum occur at similar rates between open and minimally invasive repair. Though minimally invasive repair decreases operative time and may decrease length of stay, the decision of type of procedure depends upon clinical scenario and factors unique to the individual patient.

Project description:BackgroundThere is limited data on the adult repair of pectus excavatum (PE). Existing literature is largely limited to single institution experiences and suggests that adults undergoing modified Nuss repair may have worse outcomes than pediatric and adolescent patients. Using a representative national database, this analysis is the first to describe trends in demographics, outcomes, charges, and facility volume for adults undergoing modified Nuss procedure.MethodsBecause of a coding change associated with ICD-10, a retrospective cohort analysis using the National Inpatient Sample (NIS) for patients 12 or older undergoing modified Nuss repair between 2016-2018 was possible. Pearson's χ2 and Student's t-tests were utilized to compare patient, clinical, and hospital characteristics. Complications were sub-classified into major and minor categories. Facilities performing greater than the mean number of operations were categorized as high-volume.ResultsOf 360 patients, 79.2% were male. There was near gender parity for patients over 30 undergoing repair (55.2% male, 44.8% female). In all age cohorts, patients were predominantly Caucasian. Rates of any postoperative complication differed by age (12-17 years: 30.6%; 18-29 years: 45.2%; 30+ years: 62.1%; P<0.01); older patients had higher rates of all but two subclasses of complication. Age over 30 was associated with higher charges (12-17 years: $57,312; 18-29 years: $57,001; 30+ years: $67,014; P<0.01). High-volume centers operate on older patients, had shorter lengths of stay, and comparable charges to low-volume centers.ConclusionsWomen comprise nearly half of patients undergoing modified Nuss repair after 30 years of age. There are significant differences in complication rates and charges when comparing patients by age. Patients undergoing repair at high-volume facilities benefitted from shorter lengths of stay.
