RESUMO
INTRODUCTION: Open surgical procedures in the treatment of pectus excavatum (PE) involve predetermined incisions in the parasternal cartilage and the bony ribs. For some procedures, the ribs are even dissected from the sternum for better sternal mobilization and thus better elevation of the funnel. Secure restoration of the sternocostal junction is then required, with the consequence that healing may be quite impaired. Patients may also subsequently suffer from sternocostal nonunion, for example, pseudarthrosis, and dislocated ribs, as well as pain and a recurrence of PE. MATERIALS AND METHODS: Patients underwent another open surgery with revision of the pseudarthrotic sternocostal junctions and sufficient mobilization of the anterior chest wall, followed by an open reduction and internal fixation using Matrix Rib titanium plates (Synthes, Oberdorf, Switzerland). This procedure consisted of elevating the anterior chest wall and fixing the ribs to the sternum. In 2011 and 2012, we studied this procedure, known as elastic stable chest repair (ESCR), in a series of 20 patients. The patients underwent clinical and ultrasound examinations and X-ray radiographs after the operation, after 6 weeks, and at 3- and 12-month intervals. RESULTS: Follow-up showed high patient tolerance, although a loose plate was observed in one patient and a broken plate in three patients. A stable union was achieved for all sternocostal pseudarthroses. PE improved highly significantly (p < 0.001), as the Haller index decreased from 3.6 (range: 2.7-6.6, standard deviation [SD]: 0.92) to 2.7 (range: 2.0-3.7, SD: 0.42). Pain in the anterior chest wall was significantly reduced after the operation in the majority of cases. All but one patient was mobilized already the day after the operation. CONCLUSIONS: ESCR in recurrent PE achieved functional stabilization of the anterior chest wall combined with satisfactory results.

INTRODUCTION: Some open surgical methods describe complete sternocostal dissection with subsequent resynthesis. Lack of consolidation with painful sternocostal instability and retrosternal dislocation of sternal rib tips are possible complications. MATERIALS AND METHODS: Seven patients with symptomatic unilateral sternocostal dislocation were included in this study. After diagnosis, confirmed by three-dimensional computed tomography (CT), patients underwent open surgery. All affected ribs were reset and fixed to the sternum with the aid of titanium implants. RESULTS: The patients had, on average, unilateral dislocation of 3.4 rib joints with 15.4 mm retrosternal dislocation, which was fixed with 2.3 plates. A titanium splint was also employed. The recurrent nature of the problem made procedures very time-consuming (average operation time: 3 hours 25 minutes). One patient suffered strong intraoperative bleeding requiring transfusion of blood products and access enlargement. Follow-up examinations showed high patient satisfaction (grade of 1.7; rating scale 1-6). Remaining rib instabilities were observed just as infrequently as were material failures. The sternocostal rib splint in the costal cartilage became loose and was removed. One patient exhibited a pectoral muscle asymmetry. No other complications were observed. CONCLUSION: The term "stairway phenomenon" describes the dislocation of sternocostal joints. Observed after open pectus excavatum correction it can trigger substantial physical complaints. Thus, preserving those joints during pectus repair is strongly recommended. Locking titanium plates are a safe alternative to sternocostal suture fixation and is characterized by high patient satisfaction.

INTRODUCTION: Pyoderma gangrenosum (PG) is a rare condition in infants, children and adolescents. The postoperative variant of this rapidly progressive ulceration is known as Cullen gangrene. Only a few case reports of pediatric Cullen gangrene have been published. PRESENTATION OF CASE: We present a male infant (gestational age 31â¯+â¯6 weeks) with gastroschisis and intrauterine volvulus. After multiple operations due to his complex gastrointestinal malformation, the patient showed classical symptoms of postoperative PG (PPG) 4 weeks after birth. Diagnosis could be made early in an interdisciplinary approach, differentiating intraabdominal infection (vancomycin resistant enterococcus (VRE), candida albicans) from epifascial occurrence. Treatment with high-dose steroids and immunoglobulins was initiated immediately and led to rapid recovery. DISCUSSION: The unusual combination of a complex gastrointestinal malformation and an intraabdominal infection with VRE and candida albicans made the diagnosis difficult. However, early diagnosis is crucial in the treatment of Cullen gangrene. CONCLUSION: This is the first case report of Cullen gangrene presenting in an infant (at 4 weeks of age).
RESUMO
BACKGROUND: Measurements in chest wall deformities are typically conducted using a thorax caliper or a CT scan of the chest wall. This paper focuses on the possible correlation between these two methods to validate the reliability of the thorax caliper, minimize radiation exposure, and limit the usage of expensive imaging techniques. METHODS: We evaluated 95 consecutive patients (77 pectus excavatum (PE), 17 pectus carinatum (PC), 1 mixed deformity) who received surgical correction of the anterior chest wall. The results of the external chest wall measurements and the CT-based measurements were statistically compared. RESULTS: A significant correlation between the two measurements was observed in PE and PC at the highest point of the deformation. The strongest correlation was noted in PE. We also noted a correlation between the transverse diameter of the external measurement and the inner thoracic diameter of the CT scan but not for the sagittal diameters in the upper parts of the sternum. CONCLUSIONS: Thorax caliper measurements are suitable for determining the sagittal thoracic diameter at the maximum level of the deformity and the transverse diameter with an accuracy comparable to that of CT measurements. Since these values key, the thorax caliper is reliable for monitoring and documenting chest wall malformations. LEVEL OF EVIDENCE: Study of diagnostic test. Testing previously developed diagnostic criteria in a consecutive series of patients and a universally "gold" standard-Level I.
