Tracheal stenosis can be caused by various etiologies, such as infectious disease, trauma from previous prolonged incubation, airway surgery, or external blunt trauma, and neoplasm. Recently, the development of emergency and intensive care units leads to the primary cause of airway stenosis using airway devices. The stenotic lesions can be produced at any level between the vocal cord and the site of the tip of the tube. Laryngotracheal stenosis may be due to prolonged endotrachel intubation, especially with large tube, large tracheostomy stoma, too highly placed oacheostomy, erosion by local infection, the prying action of heavyweight equipment that connects the tracheostomy to the ventilator, excessive cuff pressure, or erosion by the tip of the tube. Prevention of tracheal stenosis is of key importance by understanding and attending to these causes. We experienced three cases of tracheal stenosis occurred after use of airway devices. In first and second cases, We performed end-to-end anastomosis artier resection of stenotic segment of the trachea in a 22-year-ol4 female and a 25-year-old male. They ha6 been treated with prolonged endotracheal incubation and emergency tracheostomy, respectively, for a ventilatory support for the respiratory failure after falling down from a height. The stenotic lesions occurred at the cuff site in the first case and at the stomal level in the second case. In third case, We performed one-stage laryngotracheoplastic procedure for subglottic stenosis in a 23-year-old male. He had been treated with emergence tracheostomy which had been placed too high for a ventilators support for the respiratory failure after traffic accident. The stenotic lesion occurred at the stomal level. The postoperative courses were uneventful.

Introduction: Several investigators demonstrated that routine nasogastric decompression after abdominal surgery was unnecessary and can be safely eliminated. Some authors suggested that early feeding could be tolerated by the majority of patients after elective colorectal surgery. PURPOSE: The aim of our study was to prospectively assess the safety and tolerability of early oral feeding after colorectal surgery. METHODS: This trial included 69 patients who underwent an colon or rectal operation between April 1997 and August 1998. Patients were randomized after the operative procedure into one of two groups. Group 1: early oral feeding-all patents received a clear liquid diet on the first postoperative day followed by a regular diet as tolerated. Group 2: delayed feeding-all patients were treated in the traditional way with feeding only after the resolution of their postoperative ileus. Both groups had intraoperative nasogastric tubes that were removed at the end of surgery. The patients were monitored for vomiting, nasogastric tube reinsertion, time of regular diet consumption, complication, and length of hospitalization. The nasogastric tube was reinserted if two or more episodes of vomiting of more than 100 ml occurred in the absence of bowel movement. RESULTS: Sixty-nine consecutive patients were studied, 34 patients in group 1 (12 males and 22 females, mean age 58.1+/-12.7), and 35 patients in group 2 (16 males and 19 females, mean age 58.5+/-12.7). Significant differences were not noted in age and type of procedures. No significant differences were seen in rates of vomiting and overall complications. However, early feeding group well tolerated a regular diet (postoperative period to take regular diet of group 1: 5.4+/-4.0 days, group 2 : 8.1+/-4.6 days, p=0.013), and were discharged from hospital significantly earlier than the delayed feeding group(group 1: 14.0+/-5.1 days, group 2: 19.1+/-8.6 days, p=0.004). CONCLUSION: Early feeding after colorectal surgery is successfully tolerated by the majority of patients and led to earlier hospital discharge.

To determine the types of metabolic a cidosis using anion gap in acute infantile diarrhea and to correlate it with clinical outcome, we examined 103 infants admitted with acute diarrhea. The serum electrolytes (sodium, potassium, chloride, phosphorus), creatinine, CO2 content and anion gap were measued on first admission day. They were classified group A with normal anion gap (8~16mEq/L) and group B with increased anion gap (>16mEq/L). The results were as follows. 1) The number of group A with normal anion gap (11.6+/-3.3mEq/L) was 62 and the number of group B with incresed anion gap(21.1+/-5.5mEq/L) was 38. 2) The duration of diarrhea was significantly prolonged in group B (9.0+/-2.5 days), compared with group A (5.9+/-1.1 days)(p<0.001). 3) The duration of admission was significantly prolonged in group B(5.6+/-2.2 days), compared with group A (4.+/-01.4days)(p<0.001). 4) Infants in group B, compared with group A, were significantly more severe dehydrated (p.

Adventitial cystic disease (ACD) of the veins is a rare vascular disease. Most cases of venous ACD are located adjacent to the joint area, such as the common femoral, external iliac, and popliteal veins. To the best of our knowledge, 67 cases of venous ACD have been reported, and ACD of the superficial femoral vein (SFV) has never been reported. Herein, we report the case of a 57-year-old male who presented with swelling and discomfort in the left leg. Computed tomography venography revealed multiple cystic lesions in the left distal SFV. The patient underwent cyst excision, which relieved the compression in the vein, although mild stenosis prevailed in the SFV. After a week, thrombosis developed in the popliteal vein. The thrombosis resolved after three months of anticoagulant therapy, and the patient showed no recurrence of ACD during three years of follow-up.

BACKGROUND: Congenital aortic stenosis in children is characterized by "excessive" left ventricular hypertrophy with reduced left ventricular systolic wall stress that allows for supernormal ejection performance. We hypothesized that left ventricular wall stress was decreased immediately after surgical correction of pure congenital aortic stenosis. Also measuring postoperative left ventricular wall stress was a useful noninvasive measurement that allowed direct assessment for oxygen consumption of myocardium than measuring the peak systolic pressure gradient between ascending aorta and left ventricle for the assessment of surgical results. MATERIAL AND METHOD: Between September 1993 and August 1999, 8 patients with isolated congenital aortic stenosis who underwent surgical correction at Yonsei cardiovascular center were evaluated. There were 6 male and 2 female patients ranging in age from 2 to 11 years(mean age, 10 years). Combined Hemodynamic-Ultrasonic method was used for studying left ventricular wall stress. We compared the wall stress peak systolic pressure gradient and ejection fraction preoperatively and postoperatively. RESULT: After surgical correction peak aortic gradient fell from 58.4+/-17.6, to 23.7+/-17.7 mmHg(p=0.018) and left ventricular ejection fraction decreased but it is not statistically significant. In the consideration of some factors that influence left ventricular end-systolic wall stress excluding one patient who underwent reoperation for restenosis of left ventricular outflow tract left ventricular end-systolic pressure and left ventricular end-systolic dimension were fell from 170.6+/-24.3 to 143.7+/-27.1 mmHg and from 1.78+/-0.4 to 1.76+/-0.4 cm respectively and left ventricular posterior wall thickness was increased from 1.10+/-0.2, to 1.27+/-0.3cm but it was not statistically singificant whereas left ventricular end-systolic wall stress fell from 79.2+/-24.9 to 57.1+/-27.6 kdynes/cm2(p=0.018) in 7 patients. For one patient who underwent reoperation peak aortic gradient fell from 83.0 to 59.7 mmHg whereas left ventricular end-systolic wall stress increased from 67.2 to 97.0 kdynes/cm2 The intervals did not change significnatly. CONCLUSION: We believe that probably some factors that are related to left ventricular geometry influenced the decreased left ventricular wall stress immediately after surgical correction of isolated congenital aortic stenosis. Left ventricular wall stress is a noninvasive measurement and can allow for more direct assesment than measuring peak aortic gradient particularly in consideration of the stress and oxygen consumption of the myocardium therefore we can conclude it is a useful measurement for postoperative assessment of congenital aortic stenosis.
