Purpose: Gall bladder (GB) stones in children are rarely observed, and so reports of them have been quite limited in Korea. Therefore, we tried to assess the epidemiology and clinical features of children with GB stone diagnosed at Severance Hospital. Methods: A clinical study was performed on 18 patients below 15 years of age diagnosed with GB stone by abdominal ultrasonography or CT scan at Severance hospital from January 1999 to May 2005. Results: Concerning patients' profile, their sex ratio of male to female in total 18 cases was 2 : 1 with the mean age of $6{\pm}4.3years$. 15 patients (83.3%) were asymptomatic. Inducing factors were found in 14 children (77.8%) including ceftriaxone therapy in 6 cases (33.3%), infection in 4 cases (22.2%), spherocytosis in 3 cases (16.7%), Down syndrome and abdominal operation in 1 case (5.6%) respectively. Single stone was found in 13 cases (76.5%) and multiple in 4 cases (23.5%). 15 cases (88.2%) had the stones less than 5 mm in size, and 2 cases (11.8%) between 5 and 10 mm. 17 patients received conservative treatment, and one patient had cholecystectomy due to Meckel diverticulum. Conclusion: In this report, Pediatric GB stones are predominant in male children, without typical symptoms, having inducing factors, single and small. Recently the diagnosis of them has been increased because of the development of imaging study. But the reports for them were still rare in Korea. Therefore the study for them is more necessary to find it's clinical characteristics.

There has been no general agreement about optimal time for nerve surgery in the closed brachial plexus injury(BPI). From our early experiences, we knew by chance that spontaneous recovery in BPI patients may begin even later than 8 months after injury. Authors' strategy, which was based on our early experiences, for the treatment of closed fresh injury was 'wait and see' unlit 8 months after injury. From 1985 to 1994, we observed 103 patients with BPI. All of them did not have any operation until 8 months after injury. There were 95 men and 8 women with a mean age of 29 years. Motorcycle injury(31%) and vehicle accident(28%) were main causes of injury. Whole plexus types were observed in 56 patients(54%), upper plexus types in 29(28%), lower plexus types in 3(3%), and infraclavicular types in 15(15%). Electromyography was performed in all patients. This was repeated every three months to detect the recovery. Results were evaluated by authors' criteria, in which AMA system of brachial plexus impairment was modified. Duration of follow up was average 25 months. 47 patients(46%) showed spontaneous improvement, which was initially detected at average 7.8 months(range,3 months-16 months) after trauma by electromyography. The average score of these 47 patients improved from 14.8 points to 39.8 points.31 patients(30%) had nerve surgery such as nerve graft, neurotization or neurolysis. Average duration from injury to nerve surgery, was 10 months. Among 31 patients who had nerve surgery, 16 patients improved from preoperative 21.5 points to postoperative 36.3 points in average. Because spontaneous recovery began in average 7.8 months after injury, we think that it would be better to 'wait and see' for at least one year in patients with closed BPI expecting spontaneous recovery.

Bilateral clavicle fractures caused by a strong external force acting at the same time is a rare case. While unilateral clavicle fracture with conservative treatment shows satisfactory clinical outcome, bilateral clavicle fractures with it has drawbacks such as severe pain, difficulty in rehabilitation and breathing. We experienced a rare case of bilateral clavicle fractures with multiple rib fractures, hemo-thorax and transverse process fracture of thoracic vertebra treated with surgical intervention promoted functional recovery and comfortable breathing. So, we report this case with article review.

Acquired bronchoesophageal fistula rare. Conservative treatment such as endoscopy is widely used. The recurrence rate after endoscopic treatment, however, is not well known. We report here on a case of a 54-year-old female who presented with recurrent bronchoesophageal fistula after endoscopic treatment that filled the fistula tract with $Histoacryl^{(R)}$.

Isolated fractures of lower sacrum are commonly treated conservatively in most cases because of low energy damage and stable fracture. However, surgical treatment is required in displaced unstable fracture. But the surgical technique is not established and even case reports are not common. We reported a case of displaced transverse fracture of the lower sacrum that was treated with an open reduction and dual plate fixation.

A traumatic sternal segment dislocation in children is very rare. Of the few cases reported, some recommended surgical treatment, while others reported good results by conservative treatment. Therefore, the treatment remains unclear. This paper reports a case of completely remodeled traumatic sternal segment dislocation in a 13-year-old boy treated by the restriction of activity and periodic observations.

Lateral compartment syndrome of the lower leg is rarely observed. Hence, there may be difficulty in diagnosis as its clinical patterns are different and more complicated than usual. We report two rare cases of a 20-year-old and a 28-year-old diagnosed with isolated lateral compartment syndrome who had either a surgical or conservative treatment. The comparison was done by analyzing the progression of neurological manifestation, electromyography, and nerve conduction study for two years. In the final follow-up, the patient who underwent the surgical treatment showed a shorter recovery time. However, both patients showed a full recovery from neurologic deficits.

An eight-year-old, castrated male, Poodle dog was presented with a bite wound in the neck region. Clinical examination revealed non-ambulatory signs of tetraparesis with deep pain, and upper motor neuron changes in all limbs. Fractures of the transverse process of C1 and the dorsal spinous process of C2 were observed on the radiographs and the computed tomography (CT). Conservative therapy was performed for 1 week. However the neurological problems were not alleviated until 7 days after injury. The owners agreed to perform surgical stabilization. The surgical stabilization was performed 7 days after presentation. Ventral stabilization was performed with screws, K-wires and bone cement. The dog stood up independently after 4 weeks and was able to walk 6 weeks postoperatively. In this report we suggest that using combined stabilization techniques are effective for this type of cervical fracture in which the dorsal and ventral structures of the vertebra are severely disrupted.

Background: There are various tracheal diseseas which cause the obstruction of the trachea: postintubation tracheal stenosis, tracheal cancer, thyroid cancer, endotracheal tuberculosis, et al. Recently surgical resection and reconstruction of the trachea has been adopted as the safe method for tracheal lesions. Materials and methods: We report our experience and results of resection and reconstruction for various obstructive tracheal lesions in 38cases from 1985 to 1996. Length of resection of the trachea was up to 6 cm. Twenty lesions were approached by cervical collar incision, 12 lesions by cervicosternal incision and 4cases needed transthoracic approach. Surgical procedures consisted of resection and tracheotracheal anastomosis in 32 cases, resection and laryngotracheal anastomosis in 6cases and in addition laryngeal release was necessary to release anastomotic tension in 3cases. Results: The complications were 4 minor wound infections, 2 mild suture line granulomas, 1 vocal cord palsy, 2 pneumonias and 1 systemic candidiasis. Two patients who had poor consciousness and pnemonia and one who developed systemic candidiasis were expired after operation. Conclusion: We suggests resection and reconstruction of trachea is optimal procedure for up to 6cm long tracheal lesions. However, for the patients with poor consciousness or poor general conditions would be the conservative treatment preferred to the tracheal reconstruction because of high serious complications and mortalities.

Lymphangioma is a rare benign congenital tumor of the lymphatic system, which is commonly diagnosed before 2 years of age. In the natronal report, cystic lymphangioma was usually reported as a huge translucent mass located in the head and neck area. It's occurrence in retropharyngeal space with respiratory obstruction and swallowing difficulty in neonate is extremely rare and postoperative nasopharyngeal reflux has rarely been reported. Complete resection is the standard therapy. However, involvement of the upper airway may be determining prognosis in the extensive lymphangiomas because of the difficulty of complete excision. We present a case of cystic lymphangioma in neonate which was initially asymptomatic but gradually progressed to cause respiratory obstruction due to enlargement. After resection, nasopharyngeal reflux developed with dysfunction of the soft palate and gradually improved with conservative care over 5 months.
