Short-bowel syndrome is functionally defined as a state of malabsorption following loss of small bowel, which comprises the sequelae of nutrient, fluid, and weight loss. The proximal segment of the bowel of a patient with intestinal atresia is usually grossly distended and atonic. In contrast, distal segment is smaller. For this reason, anastomosis of the proximal and the distal segment is technically difficult and may cause no propulsion even when they are anastomosed. We experienced that continuous drip ileostomy feeding with the secretions from the proximal stoma stimulated the distal bowel to accommodate and resolved many sequelae following loss of small bowel in a patient with short-bowel syndrome due to IIIa ileal atresia.

A rare case of esophageal atresia/tracheo-esophageal fistula (EA-TEF) with an associated tracheobronchial remnant (TBR) is reported and discussed herein. A 13-month-old patient was seen with a complaint of vomiting of solid food 1 year after EA-TEF repair. An esophagogram showed a tapered narrowing in the lower segment of the esophagus. A re-operation was carried out and a pathologic examination of the resected stenotic segment revealed the presence of a TBR.

Analyzing the ECG signal, we can find heart disease. Myocardial ischemia is a disorder of cardiac function caused by insufficient blood flow to the muscle tissue of the heart. Myocardial ischemia is inscribed on ST-segment of the ECG during and after patient takes exercise or is under stress, but after long time past, the ECG pattern is return to steady state. Therefore, it is necessary to monitor and analyze the ECG signal continuously for patient or aged people. Our primary purpose is the detection of temporary change of the ST-segment of ECG automatically. In the signal processing, the wavelet transform decomposes the ECG signal into high and low frequency components using wavelet function. Recomposing the high frequency bands including QRS complex, we can detect QRS complex more easily ...

Pulmonary arteriovenous fistula is a rare congenital vascular malformation in the lung, resulting from erroneous capillary development, with incomplete formation or disintegration of the vascular septa that would normally divide the primitive connection between the venous and arterial plexus. The pathogenesis of its symptom is that unoxygenated and desaturated arterial blood enter into the pulmonary venous system directly. Recently we have experienced a case of multiple pulmonary arteriovenous fistula in a 15 year old male patient, who presented the symptom of cyanosis and dyspnea on exertion. The operation revealed well circumscribed and multilobulated aneurysmal lesion in left lower lobe with its subpleural and posterolateral basal location, and another aneurysmal lesion in inferior lingular segment of left lung. There was no abnormal connection between the fistula and systemic circulation. The left lower lobectomy was performed along with local extirpation of the inferior lingular segment of left lung. Both lesions showed angiomatous dilatation of the various sized vessels embedded in the parenchyma microscopically. Postoperative clinical course disclosed much improvement in symptoms and in the value of blood gas analysis. The patient was discharged without any complication.

Spontaneous pneumothorax is the sudden collapse of a lung usually caused by air leaking from a sub-visceral pleural bleb. Response to closed thoracotomy, needle aspiration and simple observation is usually prompt and effective. But in some cases, these are unsuccessful and open thoracotomy is indicated. Author reviewed 37 cases of open thoracotomy in spontaneous pneumothorax experienced in the Dept. of Thoracic and Cardiovascular Surgery, Pusan National University Hospital, since Jan., 1980 to Dec., 1984. The results were as follows: 1. The causes of spontaneous pneumothorax: 73.0% was primary, 27.0% was secondary origin. 2. The most frequent age group of the patient: Between 11 and 30 years old. 3. All of te patient were male. 4. The side of open thoracotomy: 58.8% was right side, 8.8% was both side. 5. The most common indication of open thoracotomy; Persistent air leakage. 6. The most frequent sites of bleb or bullae: A-P segment in the L.U.L. and apical segment in the R.U.L.

Immature teratoma can be viewed as intermediate between mature teratoma and embryonal carcinoma. Unlike the mature teratoma, elements of the three perm cell layers are incompletely differentiated and not arranged in organoid fashion In some area, more mature forms of these tissues may also be seen, Although this tumor is clearly malignant, they may not display clear-cut cytologic features of malignancy. The clinical prognosis is poor. We have experienced one case of recurrent immature teratoma. In first operation[1987, April], tumor of anterior mediastinum was removed with wedge resection of ant. segment of RUL % med. segment of RML. In 2nd operation[1990, June], recurrent teratoma of right inner thoracic wall was resected with partial 5th rib resection and wedge resection of lat. segment of middle lobe. Two months later, the 3rd operation[1990, September] was done, which was a removal of mass on thoracic wall near sup, segment of RLL and partial rib resection of 3rd, 4th & 5th. In November 1990, last operation[4th operation] was made. It was enucleation of walnut sized tumor located between medial segment of RML, and 4th. intercostal space, well encapsulated with endothoracic fascia and invaded into lung parenchyme, Adjuvant chemotherapy was done after each operation, but radiotherapy[5000 Rad] was done only after 1st operation. There was no evidence of recurrence after last operation. The patient is well-being still now.

Objective : The current literature implies that the use of short-segment pedicle screw fixation for spinal fractures is dangerous and inappropriate because of its high failure rate, but favorable results have been reported. The purpose of this study is to report the short term results of thoracolumbar burst and compression fractures treated with short-segment pedicle instrumentation. Methods : A retrospective review of all surgically managed thoracolumbar fractures during six years were performed. The 19 surgically managed patients were instrumented by the short-segment technique. Patients' charts, operation notes, preoperative and postoperative radiographs (sagittal index, sagittal plane kyphosis, anterior body compression, vertebral kyphosis, regional kyphosis), computed tomography scans, neurological findings (Frankel functional classification), and follow-up records up to 12-month follow-up were reviewed. Results : No patients showed an increase in neurological deficit. A statistically significant difference existed between the patients preoperative, postoperative and follow-up sagittal index, sagittal plane kyphosis, anterior body compression, vertebral kyphosis and regional kyphosis. One screw pullout resulted in kyphotic angulation, one screw was misplaced and one patient suffered angulation of the proximal segment on follow-up, but these findings were not related to the radiographic findings. Significant bending of screws or hardware breakage were not encountered. Conclusion : Although long term follow-up evaluation needs to verified, the short term follow-up results suggest a favorable outcome for short-segment instrumentation. When applied to patients with isolated spinal fractures who were cooperative with 3-4 months of spinal bracing, short-segment pedicle screw fixation using the posterior approach seems to provide satisfactory result.

We report a patient with combined hepatocellular-cholangiocarcinoma confined in the common hepatic duct and scirrhous type of hepatocellular carcinoma in the caudate lobe of liver simultaneously. The patient was a 55-yearsold Korean man with hepatitis B virus (HBV) carrier who was referred from a local hospital due to detected liver mass on abdominal computed tomography (CT). He has presented jaundice and weight loss for the previous 3 weeks. Laboratory examination showed AST/ALT elevation and hyperbilirubinemia. HBsAg was positive. The tumor marker study showed elevated AFP and DCP, not CEA and CA 19-9. Abdominal CT disclosed an about 2.1×0.9 cm sized soft tissue density in hilum with both intrahepatic duct (IHD) dilatations and an about 3×2.1 cm sized arterial enhancing lesion at segment 8 of the liver. Patient received 15 cycles of Gemcitabine/Cisplantin chemotherapy from February 27, 2013 to December 31, 2013. Caudate lobectomy of liver, segmental resection of bile duct and Roux-en-Y hepaticojejunostomy was performed on February 10, 2014. The final pathologic report showed double primary liver cancer, combined hepatocellular-cholangiocarcinoma in common hepatic bile duct and scirrhous type of hepatocellular carcinoma in segment 1 of the liver. This is a very unusual case in which combined hepatocellular-cholangiocarcinoma confined in the large bile duct and two rare hepatic cancers coexisted.

Purpose: After the surgical correction with sagittal split ramus osteotomy, the position of the mandibular condyle in the glenoid fossa and the proximal segment of the mandible change because of bony gap between proximal and distal segment, especially in case of mandibular setback asymmetrically. In this study, positional changes in the condyle and proximal segment after BSSRO were estimated in the mandibular asymmetry patient by analyzing the in submentovertex view and P-A cephalogram for identification of ideal condylar position during surgery. Patients and Methods: The 20 patients were selected randomly who visit Dankook Dental Hospital for mandibular asymmetry. Bilateral sagittal split ramus osteotomy with rigid fixation was performed and P-A cephalogram and submentovertex view was taken at the time of preoperative, immediate postoperative, 3 month postoperative period. Results: Intercondylar length and transverse condylar angle was increased due to inward rotation of proximal segment and anteromedial rotation of lateral pole of condyle head. The condylar position had a tendency to return to the preoperative state and after 3 months return up to about half of the immediate post-operative changes, and all the results showed more changes in asymmetry patient and deviated part of the mandible. Conclusion: Based on all these results above, surgeon should make efforts to have a precise preoperative analysis and to have a ideal condylar position during rigid fixation after BSSRO.

Purpose: To report a case of anterior segment ischemia after superior and inferior rectus muscle surgery in a patient with superior rectus muscle enlargement. This is the first report in the Republic of Korea of anterior segment ischemia after two rectus muscles surgery. Case summary: An 80-year-old male was referred to our clinic with a 3 years history of diplopia. The patient had 30 prism diopters right eye hypertropia in the primary position and downgaze limitation. The orbital computed tomography scan revealed enlargement of the right superior rectus muscle. He underwent right superior rectus recession and inferior rectus resection. On postoperative day 2, slit lamp examination revealed diffuse corneal edema, Descemet's membrane folding, an aqueous flare and a dilated pupil. Treatment with 45 mg oral steroid was initiated, and 1% prednisolone acetate and 0.5% Levofloxacin eye drops were administered. At postoperative 1 month, the patient was orthophoric in the primary position, and there was no corneal edema, pupil abnormality or aqueous flare. Conclusions: Base on the present case, the possibility of anterior segment ischemia should be considered after even two muscles surgery, and older patients with vertical muscle surgery should be considered more carefully.
