Bile duct injury complicated by bilioma after blunt liver trauma in a child.

Nonoperative management with close observation represents the standard of care for blunt liver injury, unless vital signs deteriorate or an associated injury requires emergency operation. Injuries of the biliary tract remain important concomitant lesions following liver trauma. Posttraumatic extraductal biliary collections or biliomas are rare complications of blunt abdominal traumas and only a few cases have been reported in the pediatric age group. We report a 5-year-old boy who suffered from blunt abdominal trauma that resulted in liver laceration and, eventually, bilioma formation. The patient was managed nonoperatively for liver injury. The diagnosis was confirmed by computed tomography (CT)-guided needle aspiration and percutaneous catheter drainage, which also allowed nonoperative management. The patient was symptom-free with normal liver function tests and a normal liver appearance on ultrasound examination six months after the accident. The possibility of missed bile duct injury should be considered when nonoperative management is used and close observation of the patient is necessary over a prolonged period.

Multi-slice computed tomography urography after diuretic injection in children with urinary tract dilatation.

PURPOSE: To evaluate the potential use of multi-slice computed tomography urography (MSCTU) after diuretic injection in children with urinary tract dilatation. MATERIAL AND METHODS: MSCTU was performed in 19 patients (11 boys, 8 girls, mean age 5.4 years) with suspicion of urinary tract obstruction and dilatation. Furosemide, 1 mg/kg, was injected 3 min before contrast material administration and followed by a bolus of 30 ml of physiologic saline solution immediately after application of contrast material. Excretory-phase images were obtained through the abdomen and pelvis beginning 10 min after initiation of the injection of contrast material. Maximum intensity projection (MIP) and volume rendering (VR) images were post-processed to obtain urographic views. RESULTS: MSCTU revealed pathology in 16 of 19 patients, while 3 patients had normal findings. Ureteropelvic obstruction was found in 4 patients, obstructive megaureter in 8. Both ureteropelvic obstruction and obstructive megaureter were disclosed in 1 patient, partial ureteral duplication in 1 patient, and both complete ureteral duplication and ureterocele in 2 patients. In all patients, MIP and VR images could satisfactorily show the pathologies of the urinary tract. The estimated effective average doses of MSCTU were higher than IVU. CONCLUSION: Preliminary results of furosemide-enhanced MSCTU demonstrated consistently dilated urinary tracts, obstruction levels, and underlying pathologies better than US and IVU.

Computed tomography evaluation of cavitary necrosis in complicated childhood pneumonia.

The purpose of the present study was to retrospectively investigate the chest radiograph (CR) and CT findings of childhood pneumonia complicated by cavitary necrosis, and to evaluate the role of CT in decision-making for surgical intervention. Chest CT was performed in 51 patients presenting with persistent or progressive pneumonia, respiratory distress and sepsis despite 7-10 days of appropriate antibiotic treatment and closed tube drainage. Chest radiograph and CT findings were retrospectively evaluated in 23 patients (45%) with cavitary necrosis. Chest radiographs showed consolidation in 19 of 23 patients, cavitation in five patients, parapneumonic effusions in 17 patients and air-fluid levels in the pleural space in one patient. The CT scans demonstrated consolidation and cavitary necrosis in all patients. There were parapneumonic effusions in all patients with concomitant loculated collections in six patients. Twenty-two of 23 patients had pleural thickening. In seven patients there were air-fluid levels in the pleural space. In five of these patients, CT scans demonstrated bronchopleural fistulae. On the basis of the CT and clinical findings, 11 patients underwent surgical intervention. Computed tomography is superior to CR for demonstrating cavitary necrosis complicating pneumonia, and other parenchymal and pleural complications. It also has a crucial decision-making role for surgery.

Gallbladder dyskinesia: a cause of chronic abdominal pain in children.

PURPOSE: Gallbladder dyskinesia (GD) is a well-established disorder in adults, but it is not clearly defined in the paediatric population. Therefore, the aim of this study was to review our experience in a group of children with chronic abdominal pain associated with impaired gallbladder emptying in the absence of cholelithiasis. METHODS: The records of sixteen patients who underwent cholecystectomy with the diagnosis of GD were evaluated retrospectively. Clinical presentation, symptoms, diagnostic studies, and the effect of cholecystectomy in alleviating abdominal complaints were investigated. RESULTS: All patients had symptoms of upper abdominal pain in the absence of other attributable causes associated with low gallbladder ejection fractions (GEF) < 35 %, during cholecystokinin-stimulated hepatobiliary scan (CCK-HBS), and free of gallstones on ultrasound (USG). Abdominal pain and nausea were the most common presenting symptoms. Mean GEF was 15.3 %. All patients underwent cholecystectomy. The histopathological diagnoses of all operated patients were consistent with chronic cholecystitis. Symptoms were completely relieved in all except two patients. CONCLUSION: GD should be considered in the differential diagnosis of recurrent abdominal pain in children. Patients with this condition present with biliary-type pain and investigations show no evidence of gallstones in the gallbladder. Performing a CCK-HBS establishes the diagnosis. Patients with an abnormal GEF (< 35 %) should undergo cholecystectomy. This procedure has been shown to be effective in curing the symptoms in over 80 % of patients. To avoid late diagnosis, CCK-HBS should be employed early in the evaluation of biliary colic with negative sonographic findings.

Tracheobronchial rupture due to blunt trauma in children: report of two cases.

Tracheobronchial tree injuries occur in a small number of patients after blunt chest trauma, and their occurrence is uncommon in the pediatric trauma population. The authors report two male children, one with a tracheal rupture, and the other with disruption of the main right bronchus. Mediastinal and subcutaneous emphysema resulting in airway obstruction were noted in Case 1 and soft-tissue emphysema, pneumomediastinum and tension pneumothorax were evident in Case 2 at the time of presentation. In the child with bronchial disruption, a major airway injury was suspected early on, because of a massive air leak despite two properly placed chest tubes. The definitive diagnosis was established bronchoscopically, and thoracotomy and primary repair were performed. The child with rupture of the posterior tracheal wall was diagnosed at an early stage by bronchoscopy and he was successfully managed without surgery.

Congenital malformation of the lung.

Congenital malformations of the lung are rare and vary widely in their presentation and severity. However, frequently they present with dramatic symptoms resulting in the need for prompt diagnosis and treatment. Five patients with congenital lung malformations were treated in Karadeniz Technical University Farabi Medical School Pediatric Surgery Department between June 1992 and January 1997. There were one girl and four boys. The mean age was 42 days (range 1 to 120 days) and the mean weight was 3.9 kg (range 2.4 to 5.4 kg). The following cases were included; one pulmonary agenesis, two congenital lobar emphysema, one pulmonary sequestration, and one cystic adenomatoid malformation. Respiratory distress was the most common presenting symptom. The diagnosis was performed by chest X-ray with postero-anterior and lateral view and thoracic computed tomography (CT). Associated congenital anomalies were detected in one patient and the following anomalies were found; esophageal atresia, tracheo-esophageal fistula, short distal esophagus, and small intrathoracic stomach Posterolateral thoracotomy was used for all patients and complete surgical resection was performed in four patients. Corrective surgery was delayed in one patient in whom extended respiratory support was required and he died on the ninth day due to respiratory failure. In four patients prognosis was excellent. In this article, diagnosis and treatment of congenital lung malformations are discussed.

Empyema in children.

Empyemas develop following bacterial pneumonias, thoracic trauma and surgery which are still among the common diseases, causing illness and death throughout the developing world. With the advent of potent antibiotics the mortality of empyema has been drastically reduced. In this study 52 patients (29 boys and 23 girls) with thoracic empyema were evaluated retrospectively. In this series the causes of empyema were postpneumonic in 50 patients, esophageal anastomotic leak in one patient, and thoracic trauma in one patient. The diagnosis was suspected clinically and by the finding of a pleural effusion on chest roentgenogram. Definitive diagnosis was confirmed by pleural aspiration which pus was obtained. Responsible organisms included; Staphylococcus aureus, Streptococcus pneumonia, Haemophilus influenza, pseudomonas, and Klebsiella. The most common is Staphylococcus aureus. The patients were treated in various ways; 14 patients were treated with antibiotics and thoracentesis, 38 patients were treated with a closed tube thoracostomy. Eight of 38 patients had the chest tube converted to an open empyema tubes for long term management. Fourteen of 38 patients developed abcess formation. Nine of 14 patients were treated with computed tomography guided catheter placement, five patients encountered thoracotomy and decortication. In this article, appropriate treatment and result of long-term follow-up of empyema were evaluated.

Kasabach-Merrit syndrome in infants.

METHODS: Four infants with Kasabach-Merrit syndrome syndrome have been treated at the University Hospital, Trabzon. They had large varied-site cutaneous hemangiomas. Diagnosis was performed with clinical and laboratory studies. All patients has severe thrombocytopenia and anemia. Fibrinogen and fibrin split products were examined in two patients and lower fibrinogen and over fibrin split products levels were detected in them. All patients were admitted to the intensive care unit and they were treated with antibiotics, fresh blood transfusion and thrombocyte suspension. Two out of four patients were previously treated with steroids unsuccessfully and one patient died due to disseminated intravascular coagulopathy. Three patients were treated with interferon alfa-2a and compression. RESULTS: In two patients the lesions regressed 60-80% following the five months therapy and in the other patient the lesion was completely excised after one month therapy. CONCLUSIONS: Interferon alfa-2a and compression were found to be remarkably effective in the treatment of Kasabach-Merrit syndrome.

Congenital diaphragmatic eventration: treatment and postoperative evaluation.

Three patients with congenital diaphragmatic eventration have been reported. The diagnosis was established by chest radiography which showed an abnormally elevated diaphragm. Additionally fluoroscopy, ultrasonography and pulmonary function tests were used. Diaphragmatic plication was performed in order to restore normal pulmonary parenchymal volume and the diaphragm was replaced in its normal localization. All the patients had been discharged in good condition following uneventful postoperative courses. In this study we discussed the etiology, diagnosis, treatment and postoperative courses of diaphragmatic eventration.

Bronchiolitis obliterans organizing pneumonia. An unusual cause of solitary pulmonary nodule.

Bronchiolitis obliterans organizing pneumonia (BOOP) is a pulmonary disorder with a wide spectrum of radiologic features. Usually, these are bilateral, patchy, alveolar, or ground-glass infiltrates, but other presentations have also been described. We present a case in which the radiologic appearance was a cavitated pulmonary solitary nodule. We think that this finding may justify the inclusion of BOOP in the differential diagnosis of the pulmonary solitary nodule.
