Project description:ObjectivesThe Nuss procedure for pectus excavatum involves the risk of cardiac injury during the creation of the retrosternal tunnel and during bar introduction or removal across the tunnel. A modified novel real-time technique for the safe introduction of the Nuss bar across the crucial retrosternal tunnel blind spot during introduction and removal is described.MethodsIn 2012, we devised a technique for real-time endovision-guided introduction of the Nuss bar called pectus tunneloscopy. Between February 2012 and December 2012, 6 patients with pectus excavatum had their bar introduced across the tunnel using this technique.ResultsThis technique provided safe introduction and removal of the bar during the multiple times the bar is remodelled before final fixation.ConclusionsPectus tunneloscopy is a real-time endovision surgical technique, providing safe introduction of the bar across the crucial retrosternal tunnel blind spot.

Project description:Background Pectus excavatum is the most common chest wall deformity. There is still controversy about cardiopulmonary limitations of this disease and benefits of surgical repair. This study evaluates the impact of pectus excavatum on the cardiopulmonary function of adult patients before and after a modified minimally invasive repair. Methods and Results In this retrospective cohort study, an electronic database was used to identify consecutive adult (aged ≥18 years) patients who underwent cardiopulmonary exercise testing before and after primary pectus excavatum repair at Mayo Clinic Arizona from 2011 to 2020. In total, 392 patients underwent preoperative cardiopulmonary exercise testing; abnormal oxygen consumption results were present in 68% of patients. Among them, 130 patients (68% men, mean age, 32.4±10.0 years) had post-repair evaluations. Post-repair tests were performed immediately before bar removal with a mean time between repair and post-repair testing of 3.4±0.7 years (range, 2.5-7.0). A significant improvement in cardiopulmonary outcomes (P<0.001 for all the comparisons) was seen in the post-repair evaluations, including an increase in maximum, and predicted rate of oxygen consumption, oxygen pulse, oxygen consumption at anaerobic threshold, and maximal ventilation. In a subanalysis of 39 patients who also underwent intraoperative transesophageal echocardiography at repair and at bar removal, a significant increase in right ventricle stroke volume was found (P<0.001). Conclusions Consistent improvements in cardiopulmonary function were seen for pectus excavatum adult patients undergoing surgery. These results strongly support the existence of adverse cardiopulmonary consequences from this disease as well as the benefits of surgical repair.

Project description:Pectus excavatum is the most common chest wall deformity, and some patients also have it combined with cardiac arrhythmias. It is a rare occurrence for there to be a severe conduction block that requires a temporary pacemaker implantation before the surgical correction. Here we reported a case of pectus excavatum with a second-degree atrial-ventricular (AV) block (Mobitz II) who had temporary pacemaker implantation before the Nuss procedure. The young patient had a chest wall deformity for 6 years and it got worse with age. The Haller index was 4.21, and we evaluated that he should receive the Nuss procedure. An AV block was found during the preoperative electrocardiogram examination; furthermore, Holter monitor proved that he had first-degree AV block and a second-degree AV block (Mobitz II). After consultation with the anesthesiologist and cardiologist, we suggested that a temporary pacemaker placement should be performed under local anesthesia before the minimally invasive operation and removed as soon as the patient revived from general anesthesia. A postoperative Holter monitor was implemented, and the conduction defect disappeared shortly after the operation. However, the Holter monitor showed that the conduction defect was still existed during the follow-up period, which indicated that severe conduction defects should be originated from the conduction system itself, rather than the compression to the heart. The temporary pacemaker was essential to ensure the conducting of the operation went smoothly.

Project description:BackgroundThis study aimed to examine the factors associated with the negative outcomes of Nuss procedure in adult pectus excavatum (PE) patients.MethodsForty-seven adult PE patients were enrolled in this study. Mimics 21.0 software (Materialise) was used to reconstruct the preoperative and postoperative three-dimensional (3D) thoracic model. The preoperative and postoperative pulmonary volumes and function parameters were compared. The diaphragm positions were localized, and the anteroposterior diameter (APD) of the thoracic cavity was calculated using neoteric methods. Binary logistic regression was used to reveal the association between clinical factors and altered pulmonary parameters.ResultsPostoperative lung volumes in adult PE patients decreased significantly (P<0.001). The mean preoperative lung volume was 4,592.82±946.54 cm3, which reduced to 3,976.26±867.35 cm3 postoperatively. The rate of postoperative lung volume reduction was approximately 12.1%. Physiologically, forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), and peak expiratory flow (PEF) significantly decreased after Nuss procedure, and a near 10% reduction in FVC was observed. Diaphragm elevation was positively associated with decrease in lung volumes [odds ratio (OR) =40.51; P=0.011; 95% confidence interval (CI), 2.37-692.59]. The presence of reduced thoracic APDs was significantly associated with negative pulmonary function results (OR =1.21; P=0.008; 95% CI, 1.050-1.388).ConclusionsThis study reveals that thoracic APD reduction and diaphragm elevation are associated with decreased postoperative pulmonary volumes and function in adult PE patients. Nuss procedure for adult patients with PE must be considered cautiously by thoracic surgeons, especially in patients who expect to improve their cardiopulmonary function.

Project description:BackgroundEvaluate the effect of enhanced recovery after surgery (ERAS) protocol on postoperative recovery quality of pectus excavatum patients with Nuss procedure.MethodsA retrospective study was performed on patients undergoing Nuss procedure from the Department of Thoracic Surgery of The Cancer Hospital of China Medical University between September 2016 and September 2019. Patients were divided into 2 groups by perioperative management: the traditional procedure group (T group) and the ERAS strategy group (E group). The outcome measures were postoperative drainage time, postoperative hospital time, and postoperative complications measured by the Clavien-Dindo method.ResultsOf the 168 patients from this time period, 148 met the inclusion criteria (75 in Group T and 73 in Group E). All operations involved in this study were completed successfully. There was no statistical difference between the 2 groups with respect to baseline demographics (P>0.05). In Group E, postoperative drainage time (2.53±0.72 vs. 3.45±2.07 days) and postoperative hospitalization time (4.96±1.48 vs. 7.71±7.78 days) were statistically significantly better than those in Group T (P<0.05). There was no difference in overall postoperative complications as measured by Clavien-Dindo score.ConclusionsThe measures of no indwelling urinary catheter (IDUC), laryngeal mask anesthesia, and indwelling tubule drainage can improve postoperative recovery quality of pectus excavatum patients following Nuss procedure.

Project description:BackgroundPectus excavatum (PE) is the most common congenital abnormality of the chest wall. Most patients with PE have slim bodies. Some studies have been conducted on the physical growth of children and adolescents who underwent the Nuss procedure. This study aimed to evaluate body measurement changes in adult patients with PE after the Nuss procedure.MethodsA total of 272 adult PE patients, who underwent the Nuss procedure and pectus bars removal from August 2014 to December 2020, were evaluated retrospectively. Body measurement [body height (BH), body weight (BW), and body mass index (BMI)] of the patients were collected before Nuss repair and after bar removal. We used the interquartile range (IQR) to identify and exclude outliers. Associations between changes in body measurement and clinical and radiological features were evaluated.ResultsThe BH, BW and BMI showed significantly increased after pectus bar removal, compared to pre-Nuss procedure parameters (BH 173.8 ± 5.9 cm vs. 173.9 ± 5.9 cm, P < 0.001; BW 60.3 ± 8.1 kg vs. 61.1 ± 8.8 kg, P = 0.005; BMI 19.9 ± 2.2 kg/m2 vs. 20.1 ± 2.4 kg/m2, P = 0.02). The same result were observed in the male subgroup, the HI ≥ 4 group and the male subgroup within the HI ≥ 4 group.ConclusionsThe BH, BW and BMI were significantly increased after completing surgical correction of PE using the Nuss procedure, particularly in young males and patients with more pronounced deformities.

Project description:BackgroundThis study described and evaluated the safety and efficacy of a modified single incision non-thoracoscopic Nuss procedure in pectus excavatum (PE) children.MethodsPE patients undergoing the non-thoracoscopic Nuss procedure at the Children's Hospital of Chongqing Medical University between January 2017 and December 2020 were retrospectively enrolled. The patients were divided into two groups according to operation procedures: the double incision Nuss (DN) group and the modified single incision Nuss (SN) group. Propensity score matching (PSM) was applied before evaluation of operative and postoperative characteristics to reduce selection bias.ResultsOf the 502 patients included, 261 were enrolled in the DN group, and 241 in the SN group. The operation time [35.0 (30.0-40.0) vs. 50.0 (40.0-55.0) minutes, P < 0.001] and postoperative inpatient stay [7.0 (6.0-8.0) vs. 7.0 (7.0-8.0) days, P < 0.001] of the patients in the SN group after PSM were significantly shorter than those of the patients in the DN group after PSM. Moreover, median blood loss was significantly less in the SN group after PSM than that in the DN group after PSM [2.0 (1.0-5.0) vs. 5.0 (2.0-5.0) ml, P < 0.001]. There were no significant differences in the incidence of complications between the two groups (P > 0.05). Bar removal was performed in 85 patients in the SN group within 24-42 months after surgery. Additionally, the SN group patients had a significantly lower Haller index (HI) after bar removal [2.36 (2.15-2.55) vs. 3.76 (3.18-4.26), P < 0.001] compared to the initial HI.ConclusionsThe modified procedure is safe and effective for children with PE and is worthy of clinical application.

Project description:BackgroundIt is controversial when surgery should be performed for pectus excavatum (PE). The study retrospectively compared the long-term prognosis in PE children undergoing the Nuss procedure at the age of 4-6 versus those performing surgery at the age of 12-14.Methods178 patients were included in the retrospective real-world research. Clinical Characteristics were collected at baseline. The endpoint of the study was set as the last follow-up at the age of 18 in outpatient services. Satisfaction and complication rate were set as the primary outcome and were collected at the endpoint. Hospital stay post-surgery and analgesia dosage were regard as the secondary outcome. To reduce potential bias between two different age groups, propensity score matching (PSM) analysis was analysized.ResultsThe oral analgesic dosage of children in the 4-6 years old age group is significantly lower than that of the 12-14 years old group (0.70/kg, 0.30-1.50/kg versus 1.50/kg, 0.90-2.30/kg, P < 0.001), and children in the younger age group are discharged earlier. There was no difference in overall satisfaction (89.1 %, versus 88.20 %, P = 0.99) and recurrence rate (7.2 %, versus 6.8 %, P = 0.99) between the two groups of when they reach the age of 18.ConclusionsPerforming Nuss procedure at the age of 4-6 does not affect the overall long-term satisfaction of the child or increase the long-term recurrence rate. Surgical intervention in children with pectus excavatum preschool can provide a better postoperative experience in hospital compared with intervention in adolescent.

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:BackgroundDespite advancements in minimally invasive repair of pectus excavatum (MIRPE), Nuss procedure, postoperative pain control remains challenging. This report covers a multimodal regimen using bilateral single-shot paravertebral block (PVB) and bilateral thoracoscopic intercostal nerve (T3-T7) cryoablation, leading to significant reduction in length of stay (LOS) and high rate of same-day discharge.MethodsThis is a comparative study of pain management protocols for patients undergoing the Nuss procedure at a single center from 2016 through 2020. All patients underwent the the same surgical technique for the treatment of pectus excavatum at a single center. Patients received bilateral PVB with continuous infusion (Group 1, n = 12), bilateral PVB with infusion and right-side cryoablation (Group 2, n = 9), or bilateral single-shot PVB and bilateral cryoablation (Group 3, n = 17). The primary outcome was LOS with focus on same-day discharge, and the secondary outcome was decreased opioid usage.ResultsEleven of 17 patients in Group 3 (65%) (bilateral single-shot PVB and bilateral cryoablation) were discharged the same day as surgery. The remaining Group 3 patients were discharged the following day with no complications or interventions. Compared to Group 1 (no cryoablation), Group 3 had shorter LOS (median 4.4 days vs. 0.7 days, respectively, p < 0.001) and significantly decreased median opioid use on the day of surgery (0.92 mg/kg vs. 0.47 mg/kg, p = 0.006).ConclusionFindings demonstrate the feasibility of multimodal pain management for same-day discharge after the Nuss procedure. Future multisite studies are needed to investigate the superiority of this approach to established methods.Level of evidenceIII.
