PURPOSE: We evaluated the indications of operation and radiologic findings in 12 operated DeBakey type III aortic dissections. MATERIAL AND METHODS: We retrospectively reviewed radiologic findings of 12 operated DeBakey type III aortic dissections, using CT, MRI, or aortography, and correlations were made with clinical course of the patients. RESULTS: Three cases were uncomplicated dissections. There were aneurysm rupture in 4 cases, impending rupture in 4 cases, occlusion of common lilac artery in 2 cases, occlusion of renal artery in 1 case, and compression of bronchus and esophagus by dilated aorta in 1 case. Associated clinical sign and symptoms were chest and back pain in 12 cases, claudication in 3 cases, dyspnea and dysphagia in 1 case, hoarseness in 1 case, and hemoptysis in 1 case. Post-operative complications were death from aneurysm rupture in 1 case, paraplegia in 2 cases, acute renal failure in 3 cases, and hemopericardium in 1 case. CONCLUSION: Although medical therapy is preferred in management of DeBakey type Ill aortic dissection, surgical treatment should be considered in patients with radiological findings of aortic rupture, impending rupture, occlusion of aortic major branches.

PURPOSE: To assess the postoperative CT findings of aortic aneurysms or dissections treared by resection- and-graft replacement or continuous-suture graft-inclusion technique MATERIALS AND METHODS: We reviewed postoperative follow-up CT findings of 14 patients, 19 cases. There were 8 patients(10 cases) of aortic aneurysm and 6 patients(9 cases) of aortic dissecton which involved the thoracic aorta in 9 patients(13 cases) and abdominal aorta in 5 patients(6 cases). The interval of follow-up after operation was from 9 days to 2 year 9 months. On CT scans, we analyzed the appearance of graft materials, differences of CT findings between two surgical techniques, and normal or abnormal postoperative CT findings. RESULTS: Most of grafts appeared as hyperdense ring on precontrast scan, and all of them were not seperated from aortic lumen on postcontrast scan. On CT findings of patients who were operated by continuous-suture graft-inclusion technique, perigraft thrombus was concentrically located with sharp demarcation by native aortic wall and its density was homogeneous, but in cases of those operated by resection-and-graft replacement, perigraft hematoma was eccentrically located with indistinct margin and its density was heterogeneous and native aortic wall could not be delineated. In patients without complication, perigraft thrombus or hematoma(15 cases), perigraft calcification(11 cases), residual intimal flap(6 cases), graft deformity(4 cases), perigraft air(2 cases) and reconstructed vessels(1 case) were noted. And in one patient with complication, perigraft flow was noted with more increased perigraft hemaroma. CONCLUSION: Precise knowledge of the differences of CT findings between two surgical techniques and nor- mal postoperative CT findings is crucial to evaluate the postoperative CT findings in aortic aneurysm and dissection.

BACKGROUND: As the frequency of colonoscopic approaches increases, we need a less painful premedication for colonoscopy. We used midazolam as a premedication agent. It has more rapid onset of action than that of diazepam and its duration is shorter. The purpose of this study was to examine the clinical application of midazolam. METHODS: Fifty patients underwent colonoscopies. An average dose of midazolam, 0.07 mg/kg, was given to patients intravenously as premedication. We measured systolic and diastolic blood pressures, pulse rates, respiratory rates, and oxygen saturation (SaO2) using pulse oxymetry before and after the injection. A Trieger test was accomplished before and after the procedures. We examined the levels of consciousness with verbal and physical stimulation during the colonoscopy. The examiners noted the degree of amnesia and pain after colono-scopy. We examined the patients' satisfaction and endoscopists' assessments. RESULTS: 1) Systolic, diastolic blood pressures and respiratory rates showed no significant changes. But, pulse rates increased meaningfully at 15 minutes after the injection of midazolam (p <0.05). 2) The Trieger test showed meaningfully increased numbers of missed dots after the injection of midazolam. 3) The levels of consciousness during the test showed alertness in 22 patients (44%), drowsy mentality in 22 patients (44%) and stuporous mentality in 6 patient (12%). 4) The degree of amnesia after examination showed recall in 26 patients (52%), partial recall in 10 patients (20%) and total amnesia in 14 patients (28%). 5) Forty-five patients (90%) acknowledged this procedures to be more comfortable than previous procedures. CONCLUSIONS: Midazolam stabilized vital signs and oxygen saturation, therefore midazolam can be used safely as premedication for colonoscopy. Thirty-six patients (72%) recalled the procedures totally or partially. But, the relief of pain compared favorably to the degree of amnesia. We concluded that mida-zolam (0.07 mg/kg) was the safe and effective premedication for colonoscopy.

Collagenous colitis is characterized clinically by chronic watery diarrhea and pathologically by increased subepithelial collagen deposition associated with an inflammatory infiltrate in the lamina propria. Its etiology is still unclear, although a variety of associated diseases such as rheumatic syndromes, scleroderma, and thyroid diseases have been reported. We report a case of collagenous colitis following the prolonged use of NSAIDs. A 72-year-old woman who has taken NSAIDs for many years due to some dermatologic problems was admitted to the hospital because of chronic watery diarrhea and colicky abdominal pain of 3 months duration. There was no abnormal physical finding except cachectic appearance due to weight loss of 10kg during 3 months. Stool examination for ova and parasites and fat was negative, and stool culture for bacterial pathogens was negative. In complete blood count, there were relative eosinophila and mild anemia. Total serum protein and albumin was low, and thyroid function, RA factor, FANA were all normal. Results of upper and lower gastrointestinal contrast radiographs were normal. Sigmoidoscopy revealed normal colonic mucosa but she had a thick subepithelial collagenous deposit and chronic inflammation in lamina propria on colonic biopsy. Based on the above findings, she was diagnosed as collagenous colitis. Diarrhea improved after withdrawing NSAIDs and the treatment with oral prednisolone. In the post-treatment biopsy, the thickness of the collagen hand was diminished. Collagenous colitis is now recognized as one of the common causes of chronic diarrhea of obscure origin and NSAIDs may play an etiological role in some patient with collagenous colitis.

A 43 years old woman with a previous history of healed tuberculosis presented with a recurrent hemoptysis. On a broncoscopy inspection, three nodular shaped mass-like lesions (0.5cm in diameter) were found on the right lower lobar bronchus. Massive hemoptysis occurred when the specimen were taken during bronchoscopy. The bleeding could not be controlled by non-surgical treatment. Consequently, she underwent a right lower lobectomy in order to control the bleeding. The patient died of respiratory failure 3 days later. A brochoscopic biopsy revealed an abnormal blood vessel just beneath the bronchial respiratory epithelium.

Chronic idiopathic inflamatory bowel disease, espcaially Crohn's disease, is frequently complicated with low gastrointestinal stricture. Besides medical treatment of active inflammation, there is no specific, conservative approach to this complication, Repetitive surgery with extensive resections, leading to short bowel syndrome, is often necessary. Balloons have been used for a variety of gastrointestinal stenoses including esophageal, small intestinal, and colonic stricture. Balloon dilation offers many theoretical advantages (safety, and patient comfort) over dilation with bougies. Especially, the availability of large diameter balloon dilators, which pass through the biopsy channel of standard endoscopes (through-the scope balloon or TTS balloon), has promised efficient direct-vision dilatation of strictures without the need of guide wires or fluoroscope. We report a case of colonic Crohn's stricture dilated successfully using TTS balloon catheter.
