Medical photography: a reliable and objective method for documenting the results of reconstructive surgery of pectus excavatum.

Patients with a pectus excavatum frequently experience medical problems such as dyspnoea, fatigue and palpitations. After surgical intervention most patients are alleviated of their symptoms. Pectus excavatum can easily be diagnosed by a proper inspection of the chest. In the Atrium Medical Center photographic documentation of the deformation of the chest is part of the treatment protocol before and after surgical correction of a pectus excavatum. In addition to the normal photographic routine two special recording techniques are applied: measuring the depth of the excavation with a rule, and documenting the depth of the excavation in a 3-D grid-projection image. The applied 3-D technique (raster stereography) can also be an asset to other medical specialty areas in which changes in body shape and appearance play a major role.

Addition of Video-Assisted Thoracoscopic Surgery to the Treatment of Flail Chest.

BACKGROUND: Video-assisted thoracoscopic surgery (VATS) is increasingly used in chest trauma for diagnostic and therapeutic purposes. In this report we describe our single-institutional experience with VATS in the surgical treatment of patients with flail chest after high-energy trauma. METHODS: From January 2013 to July 2014, 15 patients with flail chest after high-energy trauma were treated in our hospital. The Injury Severity Score (ISS) ranged from 16 to 44. Rib fixation was performed with precontoured plates or intramedullary splints. In all, patients we additionally used VATS to explore the thoracic cavity and evacuate any hemothorax. RESULTS: In 10 patients a prominent hemothorax was present, which needed evacuation. The median operative time was 120 minutes (range, 60 to 180 minutes), with a median blood loss of 150 mL (range, <100 to 400 mL). The mean stay in the intensive care unit was 5.27 days (SD 6.79). Ten patients were extubated directly after operation in the operating room. The other 5 patients were extubated after 1 to 13 days. The mean duration of mechanical ventilation was 2 days (SD 4.17). No patient required a tracheostomy. Three patients had minor postoperative adverse events. All patients were discharged after 6 to 44 days (mean, 11.9 hospitalization days) (SD 9.57). CONCLUSIONS: We believe VATS is effective and safe and can be of additional value by providing the possibility to adjust the planned incision for rib fixation and decrease the area of muscle destruction. Additional pulmonary or mediastinal pathologic conditions can be identified and complete evacuation of hemothorax can be achieved simultaneously.

Preoperative exercise therapy in lung surgery patients: A systematic review.

OBJECTIVES: The impact of postoperative complications after lung surgery for cancer is substantial, with the increasing age of patients and the presence of comorbidities. This systematic review summarises the effects of Preoperative Exercise Therapy (PET) in patients scheduled for lung surgery on aerobic capacity, physical fitness, postoperative complications, length of hospital stay, quality of life and recovery. METHODS: A systematic search on PET prior to lung surgery was conducted. The methodological quality of the included studies was rated using the Physiotherapy Evidence Database (PEDro) scale. The agreement between the reviewers was assessed with Cohen's kappa. RESULTS: A total of eleven studies were included with a methodological quality ranging from poor to good. The agreement between the reviewers, assessed with the Cohen's kappa, was 0.79. Due to substantial heterogeneity in the interventions across the included studies, it was impossible to conduct a meta-analysis. The most important finding of this systematic review was that PET based on moderate to intense exercise in patients scheduled for lung surgery has beneficial effects on aerobic capacity, physical fitness and quality of life. Also PET may reduce postoperative complications and length of hospital stay. CONCLUSION: PET may have beneficial effects on various physical fitness variables and postoperative complications in patients with lung cancer scheduled for surgery. Future research must focus on developing patient tailored exercise programs and investigate the influence of co-existing comorbidities on the outcome measures. Definitions of PET, including timing, (acceptable) duration, intensity and exercise training methods should be determined and compared.

Inter- and intraobserver agreement on the Load Sharing Classification of thoracolumbar spine fractures.

The Load Sharing Classification (LSC) allocates one to three points to each of three different radiological characteristics of traumatic thoracolumbar fractures: the vertebral body involved in the fracture, the displacement of the fracture parts and the kyphotic deformity. Added up, a minimal score of three and a maximal score of nine can be obtained. When the LSC score is three to six, a short segment pedicle screw fixation suffices. When the LSC score is seven to nine, a high rate of failure in patients with a short segment pedicle screw fixation exists. In these cases an anterior stabilising procedure of the spine is advised. The LSC has been examined by Dai and Jin, who claim an almost perfect inter- and intraobserver agreement, according to the Landis and Koch criteria. Dai and Jin only present results for the separate three items of the LSC and for the total LSC scores. Observer agreement for the two LSC score categories (three to six and seven to nine) have not been studied. The aim of this study is to study the inter- and intraobserver agreement of the LSC for the total score, the three separate items and also for the two LSC score categories. Three observers determine twice the LSC scores of forty traumatic thoracolumbar fractures. The average standard Cohen's kappa values for the separate LSC items range between 0.06 and 0.48. For the total LSC score the average standard Cohen's kappa and weighted kappa values are 0.22 and 0.67 respectively. For the two LSC score categories, there is unanimous agreement in 55% of the cases and a majority agreement in 40%. In the remaining 5% of the fractures there is a split decision. Standard Cohen's kappa value for the two LSC score categories is 0.53. The standard Cohen's kappa values can be rated as fair to moderate. From these data it can be concluded that the inter- and intraobserver reliability of the Load Sharing Classification of Spinal fractures can be rated as fair.

Early removal of the chest tube after complete video-assisted thoracoscopic lobectomies.

OBJECTIVE: Chest tubes induce morbidity such as pain, decrease mobility, increase the risk of infection, and prolong the length of hospital stays. This study evaluates a chest-tube protocol containing a high-drainage threshold and a short time period of drainage. METHODS: A retrospective study was performed with data collected from all elective complete video-assisted thoracoscopic (c-VATS) (bi-)lobectomies between March 2006 and December 2009. All patients had one chest-tube, postoperatively. The chest tube was removed if there was no air leakage and there was a drainage volume of 400 ml (24 h)(-1) or less. We aimed to remove the chest tube on postoperative day 1. RESULTS: This series consists of 110 lobectomies and six bilobectomies. The median duration of chest-tube placement was 1.0 day. In 58.8% of patients (confidence interval (CI) 95%: 49.5-68.0), the drain was removed within 24 h of operation and in 82.5% (CI 95%: 74.2-88.7) within 48 h. In six (6.2%) patients, subcutaneous emphysema developed while the drain was still in place, and was treated with removal of the drain. Persistent air leakage was seen in four (3.4%) patients. One (0.9%) persisting pneumothorax was diagnosed. A pneumothorax after removal of the drain was not diagnosed. No major complications developed in 98 patients (84.5%). The median day of discharge was postoperative day 4. CONCLUSIONS: This study shows it is safe, after c-VATS (bi-)lobectomy, to remove the chest tube within 24 h in 58.8%, and within 48 h in 82.5% of patients. As was also shown in other studies, this leads to shorter length of hospital stays, lower costs, and most importantly, reduces patient morbidity without the added risk of complications.

The role of video-assisted thoracic surgery in the surgical treatment of superior sulcus tumors.

The surgical resection of sulcus superior tumors, also referred to as Pancoast tumors, remains a challenging surgical procedure. A patient presented with a superior sulcus tumor situated anterior in the thoracic inlet. The tumor was resected through a transmanubrial approach of Grunenwald combined with a video-assisted thoracic surgery (VATS) lobectomy. VATS can be very helpful in determining the exact location of the resection and at the same time performing a lobectomy avoiding extra morbidity due to a classical thoracotomy.

Complete video-assisted thoracoscopic surgery lobectomy and its learning curve. A single center study introducing the technique in The Netherlands.

Data regarding the benefits for the complete video-assisted thoracic surgery (c-VATS) lobectomy over the open lobectomy are numerous. This article describes the experience of introducing this technique in a training hospital, the first reported cohort in The Netherlands. From March 2006 to November 2008, all patients operated on for proven or suspected lung cancer were analyzed. Prospective data from these patients were evaluated. A subgroup analysis for the c-VATS lobectomy is presented. A total of 184 operations were performed on 172 patients. In 122 (66.3%) of the operations the resection ended in a lobectomy of which 70 were done by complete thoracoscopic procedure. For the c-VATS lobectomy the mean operating time was 179 min, with a mean blood loss of 444 ml. The median hospital stay was four days. Complications were present in 10% of c-VATS lobectomies. No mortality was seen in the c-VATS group. After thorough evaluation and training, c-VATS lobectomy is a safe procedure that can be performed in a relatively low volume hospital. It has exceptional short-term benefits. For training purposes all operations must start thoracoscopically. All patients must be operated according the intention to treat method.

Cost-effectiveness of the treatment of traumatic thoracolumbar spine fractures: Nonsurgical or surgical therapy?

BACKGROUND: Spinal fractures can be an important cause for disabling back pain. Therefore, in judging the cost-effectiveness of nonsurgical or surgical therapy, not only direct costs but also the indirect costs should be calculated. In this prospective randomized study, the costs incurred by nonsurgically and surgically treated patients with a traumatic thoracolumbar spine fracture without neurological involvement were analysed. MATERIALS AND METHODS: 32 patients with a traumatic thoracolumbar spine fracture were prospectively randomized for operative or nonsurgical treatment. Patients were sent a questionnaire every three months to inquire about work-status, additional health costs and doctor visits. The patients who have minimum followup of two years were included. RESULTS: Of thirty-two patients, 30 met the criterion of the followup period of at least two years. Fourteen patients received nonsurgical therapy, while 16 received surgical treatment. Direct costs of the treatment of nonsurgically treated patients were €10,608 ($12,730). For the operatively treated group, these costs were €18,769 ($22,523). Indirect costs resulted in a total of €219,187 ($263,025) per nonoperatively treated patient. In the operatively treated group, these costs were €66,004 ($79,206). CONCLUSION: In the treatment of traumatic thoracolumbar spine fractures, the indirect costs exceed the direct costs by far and make up 95.4% of the total costs for treatment in nonsurgically treated patients and 71.6% of the total costs in the operative group. In view of cost-effectiveness, the operative therapy of traumatic thoracolumbar spine fractures is to be preferred.

Spine fractures caused by horse riding.

STUDY DESIGN: Retrospective study and review of literature. OBJECTIVES: Study of demographic data concerning spinal fractures caused by horse riding, classification of fractures according to the AO and Load Sharing classifications, evaluation of mid-term radiological results and long-term functional results. METHODS: A review of medical reports and radiological examinations of patients presented to our hospital with horse riding-related spine fractures over a 13-year period; long-term functional follow-up is performed using the Roland Morris Disability Questionnaire (RMDQ-24). RESULTS: Thirty-six spine fractures were found in 32 patients. Male to female ratio is 1:7. Average age is 33.7 years (8-58 years). The majority of the fractures (78%) are seen at the thoracolumbar junction Th11-L2. All but two patients have AO type A fractures. The average Load Sharing Classification score is 4.9 (range 3-9). Neurological examinations show ASIA/Frankel E status for all patients. Surgical treatment is performed on ten patients. Mean follow-up for radiological data is 15 months (range 3-63). Functional follow-up times range from 1 to 13 years with an average follow-up of 7.3 years. Mean RMDQ-24 score for all patients is 5.5 (range: 0-19), with significantly different scores for the non-operative and surgical group: 4.6 vs 8.1. Twenty-two percent of the patients have permanent occupational disabilities and there is a significant correlation between occupational disability and RMDQ-24 scores. CONCLUSIONS: Not only are short-term effects of spine fractures caused by horse riding substantial but these injuries can also lead to long-term disabilities.

Treatment of traumatic thoracolumbar spine fractures: a multicenter prospective randomized study of operative versus nonsurgical treatment.

STUDY DESIGN: Multicenter prospective randomized trial. OBJECTIVE: To test the hypotheses that thoracolumbar AO Type A spine fractures without neurologic deficit, managed with short-segment posterior stabilization will show an improved radiographic outcome and at least the same functional outcome as compared with nonsurgically treated thoracolumbar fractures. SUMMARY OF BACKGROUND DATA: There are various opinions regarding the ideal management of thoracolumbar Type A spine fractures without neurologic deficit. Both operative and nonsurgical approaches are advocated. METHODS: Patients were randomized for operative or nonsurgical treatment. Data sampling involved demographics, fracture classifications, radiographic evaluation, and functional outcome. RESULTS: Sixteen patients received nonsurgical therapy, and 18 received surgical treatment. Follow-up was completed for 32 (94%) of the patients after a mean of 4.3 years. At the end of follow-up, both local and regional kyphotic deformity was significantly less in the operatively treated group. All functional outcome scores (VAS Pain, VAS Spine Score, and RMDQ-24) showed significantly better results in the operative group. The percentage of patients returning to their original jobs was found to be significantly higher in the operative treated group. CONCLUSIONS: Patients with a Type A3 thoracolumbar spine fracture without neurologic deficit should be treated by short-segment posterior stabilization.
