Filter by:Pectus excavatum is the most common congenital anterior chest wall deformity, known to occur in 1:400 of new-borns. Complaints may be of cosmetic nature or as a consequence of (cardio)pulmonary impairment. Part of the current work-up of pectus excavatum patients in Zuyderland Medical Centre (Heerlen, the Netherlands) is visual documentation of the deformity. Visual documentation is performed utilising a single-reflex camera and consists of 5 standard photographs (acquired from different angles) and two specialised recordings. These specialised recordings encompass a recording to measure the pectus excavatum's depth and a raster stereography recording to create a three-dimensional perspective. However, this form of visual documentation is not efficient, as it is time- and labor-intensive for the photographer and patient. Recently, another study started that aims to investigate whether three-dimensional (3D) optical surface scans can be used to determine pectus severity, as compared to chest radiographs and computed tomography scans (3DPECTUS study; METCZ20190048; NCT03926078). Building on this study it was determined whether 3D optical surface scans can be used as a tool to document the surface geometry of pectus excavatum. To determine whether the current standard photographs and specialised recordings can be replaced by a 3D scan, both methods are compared. To make this comparison, the pectus excavatum depth was chosen as an objective measure of agreement. If there is good agreement, it is assumed that the standard photos can be replaced by a 3D photo in the current work-up. This will subsequently result in a time saving as well as a reduced burden for the patient while acquisition of 3D scans takes only 10 seconds.
Chest wall deformities are the development of ribs, cartilage and sternum that form the chest wall together with isolated or abnormalities of the musculoskeletal system. Pectus excavatum and carinatum deformities are most common. It is reported that individuals with this problem have posture and physical impairments, difficulty in psychosocial relations and decreased quality of life.Therefore, in this study, the investigators aimed to evaluated the physical and psychosocial characteristics of patients with pectus excavatum and carinatum compared with healthy controls.
Pectus excavatum (PE); It is an anterior chest wall deformity, characterized by varying degrees of depression of the sternum and costal cartilage, usually occurring at birth or in the first year of life. In the treatment of non-severe PE; vacuum bell orthosis and physiotherapy (especially exercise) is recommended as an alternative to surgery. Although there is no literature or consensus about the role of physiotherapy, it is believed that it plays an important role in preventing or correcting deformities and creating a good cosmetic appearance. Therefore, in this study, the investigators aimed to investigate the effectiveness of exercise therapy in addition to vacuum bell therapy.
The purpose of this study is to evaluate the efficacy of erector spinae plane (ESP) block in children after pectus excavatum repair (nuss procedure).
Preoperative fasting is intended to lower the amount of gastric contents in order to decrease the incidence of aspiration associated with endotracheal intubation. However, recent studies show that longer fasting time does not reduce aspiration associated complications. Especially in pediatric patients, long fasting time increases patients' unpleasantness and therefore increases postoperative recovery quality. It also induces hypoglycemia. In many studies, ingesting clear liquids 2 hours up to general anesthesia decreases gastric contents and therefore the incidence of aspiration pneumonia, postoperative nausea and vomiting. Therefore anesthesiologist associations in the US and Europe recommend to drink small amount of clear liquid (water) up to 2 hours before the surgery. Nuss bar operation, or repair surgery of pectus excavatum is mostly done in pediatric patients. The procedure itself is very painful, requiring paramount amount of analgesics. Use of opioid analgesics increases postoperative nausea and vomiting. In this study, our aim is to evaluate preoperative fasting time and how preoperative supplement of clear liquid affects the quality of recovery postoperatively.
Pectus excavatum is the most common anterior chest wall deformity that affects up to 1:400 of newborns. If an operative correction is indicated, patients are often operated via the Ravitsch or Nuss bar procedure. The latter (i.e. the Nuss bar procedure) is the most commonly performed procedure. During this procedure one or more metal bars are inserted behind the sternum to push the sternum back into its normal position. These bars remain in situ for two-to-three years before being removed. Despite the fact that the Nuss bar procedure is regarded as an effective procedure, retraction may occur after removal. A recent study has investigated this phenomenon, utilizing three-dimensional (3D) optical surface scans acquired before and after Nuss bar removal. The authors found statistically significant changes to occur in chest wall dimensions directly after, as well as between 2 and 8 weeks after Nuss bar explantation, in comparison to the situation just prior to bar removal. They, moreover, found the time the bar was in situ to be predictive for retraction. However, the authors also stressed that further studies are needed to reinforce their preliminary findings and perform long-term assessments. Subsequently, a similar study with long-term assessments will be conducted.
Pectus excavatum is the most common anterior chest wall deformity, affecting up to 1:400 of newborns. The current gold standard to quantify the extent of deformity is by calculating the Haller Index based on a Computed Tomography (CT)-scan. However, as such scans inescapably imply exposure to ionizing radiation, novel imaging techniques have been investigated. Three-dimensional optical surface scanning is a promising new technique to acquire the trunks' three-dimensional (3D) surface topography. Based on this 3D scan, one is able to calculate the external Haller Index that is known to highly correlate with the conventional gold standard Haller Index that is based on internal measures. Both the conventional and external Haller Index are known to be affected by the respiratory phase in which the scan is acquired, however, what is the effect of patient position on the external Haller Index, and if affected, how should one correct for this phenomenon? To investigate this, a retrospective single-centre pilot study will be conducted.
This will be a prospective study to determine the association between specific genotypes, epigenetics, behavioral, social and biological factors, with the phenotypes, defined by pain perception, postoperative pain, analgesic effects, side effects to perioperative analgesics, chronic postoperative pain, and gene expression in patients following pectus excavatum repair.
Pectus excavatum (PE) is the most common anterior chest wall deformity. Currently, a chest radiography (CR) or Computed Tomography (CT) scan is acquired to determine and objectify pectus severity using the Haller Index. Alongside other determinants, the Haller Index value is used in the proces of clinical decision making and determine surgical candidacy. However, cross-sectional imaging based calculation of the Haller Index implies exposure to ionizing radiation that should be limited at all times to diminish the cumulative long-term risks of malignancy. Especially in pectus patients that often concerns children. Three-dimensional (3D) optical surface imaging offers a non-invasive, radiation-free alternative that may be used to obtain thoracic measures and determine pectus severity. However, for 3D images/scans to be used as a diagnostic tool in the proces of clinical decision making and determine surgical candidacy, its diagnostic accuracy should be evaluated. This will be investigated utilizing a pilot study design as no prior accuracy studies are available.
The main objective of this study is to characterize the cardiorespiratory functional gain in patients with pectus excavatum following corrective surgery.
