High Grade Sarcoma Arising from the Chest Wall of a Chronic Tuberculous Empyema: A case report / 대한흉부외과학회지

A 50 year old male patient was admitted due to fever and left upper-quadrant abdominal pain. He had a history of previous treatment for pulmonary TB and splenectomy due to aplastic anemia. A large peritoneal abscess with connection to a chronic left side tuberculous empyema thoracis was diagnosed on admission. Chest CT also revealed a soft tissue lesion on the left anterior chest wall. Staged drainage of the peritoneal lesion followed by left side pleuropneumonectomy with chest wall resection was performed. The pathologic studies showed a high grade sarcoma of the chest wall.

Effects of Additional Pleurodesis with Dextrose and Talc-Dextrose Solution after Video Assisted Thoracoscopic Procedures for Primary Spontaneous Pneumothorax

Recurrence after thoracoscopic surgery for primary spontaneous pneumothorax is a lingering problem, and many intraoperative methods to induce pleural symphysis have been introduced. We analyzed the effects of chemical pleurodesis during thoracoscopic procedures. Between August 2003 and July 2005, 141 patients among indicated surgical treatment for primary spontaneous pneumothorax in two hospitals of our institution allowed this prospective study. The patients were randomly assigned to 3 groups: thoracoscopic procedure only (group A, n=50), thoracoscopic procedure and pleurodesis with dextrose solution (group B, n=49), and thoracoscopic procedure and pleurodesis with talc-dextrose mixed solution (group C, n=42). There was no significant difference in demographic data among the three groups. The two groups that underwent intraoperative pleurodesis had significantly longer postoperative hospital stays (A/B/C: 2.50+/-1.85/4.49+/-2.10/6.00+/-2.58 days; p=0.001) and a higher incidence of postoperative fever (A/B/C: 10.0/22.45/52.38%; chi-square= 21.598, p=0.00). No significant differences were found for recurrence rates or the number of postoperative days until chest tube removal. Therefore, the results of our study indicate that intraoperative chemical pleurodesis gives no additional advantage to surgery alone in deterring recurrence for patients with primary spontaneous pneumothorax. Thus, the use of such scarifying agents in the operating room must be reconsidered.

Clinical Appilication of Endobornchial Cryoablation That's Performed through Flexible Bronchoscope for Treating Tracheobronchial Ostruction / 대한흉부외과학회지

BACKGROUND: Emergency airway access is essential when a patient has dyspnea that's due to tracheal or bronchial obstruction. Such methods as laser therapy and PDT are now being used for the treatment of tracheal obstruction that's due to benign diseases or nonsurgical malignant diseases. Cryotherapy is a method that uses extreme hypothermia for freezing a tumor to cause necrosis. In this study, we have evaluated the clinical effectiveness of performing endobronchial cryoablation through a flexible bronchoscope. MATERIAL AND METHOD: 10 patients with tracheal obstruction that was due to endotracheal tumors were evaluated between May 2005 and May 2007. Eight were male and the mean age of the 10 patients was 59.4+/-18.4 years. Three cases of tracheal obstruction were due to benign tumors and 7 were due to malignant tumors. The obstruction sites were 3 at the trachea, 3 at the carina and 4 at the bronchus. A flexible bronchoscope was inserted and the tumor was eliminated using a flexible cryoprobe. Follow up bronchoscopy was performed at 1 week and 1 month after cryoablation, and then we evaluated the decrease of dyspnea, the improvement of the performance and the complications of the procedures. RESULT: Complete remission was achieved in 4 patients and partial remission was achieved in 6 patients. Complications such as hemoptysis (100%), and cough (50%) were noted. Hemoptysis was spontaneously resolved in 3 to 8 days (mean: 4.9 days). A decrease in dyspnea and improvement in the performance was noted in all patients. CONCLUSION: Endobronchial stenosis plays a detrimental role in the life quality of a terminal cancer patient. Due to its simplicity and effectiveness for controlling bleeding, endobronchial cryoablation is considered to be a safe method that is clinically applicable to a wide range of tumors, including the removal of large tumors. We concluded that endobronchial cryoablation through a flexible bronchoscope is a safe, effective method for treating tracheobroncheal obstructions.

Repair of Posttraumatic Tricuspid Regurgitation Using Artificial Chordae and an Annuloplasty Ring / 대한흉부외과학회지

A 52-year-old man was taken to the emergency room following a motor vehicle accident. An echocardiogram showed moderate to severe tricuspid regurgitation due to rupture of the anterior chordae. An operation to repair the traumatic tricuspid regurgitation was recommended; however, the patient refused because he was asymptomatic. Two years later, he developed mild generalized edema and dyspnea. The echocardiogram revealed progressive severe tricuspid regurgitation and annular dilatation. We treated the posttraumatic tricuspid regurgitation successfully using artificial chordae and ring annuloplasty.

Reconstruction of the Superior Vena Cava with Extra-luminal Bypass Shunt / 대한흉부외과학회지

We operated on a 41-year-old man using venous bypass shunt for superior vena cava (SVC) syndrome caused by mediastinal fibrosis. The patient had substantially high venous pressure and high risk of postoperative neurologic deficits. The collateral veins were deemed to be interrupted during the surgical reconstruction of SVC. Treatment included resection of the obstructed SVC and innominate vein and reconstruction with an autologous pericardial tube graft. During the operation, venous drainage from upper body was maintained with an extraluminal bypass shunt. The shunt was effective at prompt relief of venous hypertension, eliminating the time constraints, and preventing the postoperative complications.

Prevalence and risk factors of gallbladder polyps in health screening subjects / 대한내과학회지

BACKGROUND: Gallbladder (GB) polyps are now increasingly detected by ultrasonography. We investigated the prevalence and risk factors of GB polyps in health screening population. METHODS: An ultrasonographic study of GB polyps were conducted in 35,012 subjects who received a paid health screening examination at Samsung Medical Center. Controls, twice the subjects with GB polyp, were randomly selected from the cases with normal GB. The demographic characteristics and biochemical parameters were recorded. RESULTS: The overall prevalence of GB polyps was 2.94% (1,330/15,573). Among them, 3.63% were men, 2.09% were women. In both males and females, the prevalence was highest in their 40s. The diameter of GB polyps ranged from 2 mm to 20 mm (mean 4.5 mm). Most polyps (98.3%) were less than 10 mm in diameter. Of 1,030 subjects, 64% had a single polyp and 36% had multiple polyps. Multiple logistic regression, with reference group of body mass index (BMI, <22.5 kg/m2), showed odds ratio of 1.074 and 1.864 for BMI groups of 22.5-24.9 and 25 or more respectively. In contrast, other demographic characteristics and biochemical parameters, such as age, smoking, alcohol use, glucose, liver function tests, lipid profiles and HBsAg carriage were lack of any relation to GB polyps. CONCLUSIONS: GB polyps are not likely to be rare in Korean adults despite their low prevalence compared to other reports. The body mass index may be a risk factor for GB polyps.

A Case of Concurrent Esophageal and Gastric Double Primary Cancer Treated by Surgery and Chemotherapy / 대한소화기내시경학회지

Double primary cancer of the stomach and esophagus has been revealed a very low incidence in the world except Japan and reported only 6 cases in Korea. Furthermore, it is difficult to manage this type of double cancer because esophageal cancer has a biologic tendency to early metastasis. This paper is concerned with a case of double primary cancer, which we have synchroniously confi~rmed esophageal squamous cell carcinoma and gastric adenocarcinoma with gastrofiberscopic biopsy, and then treated them by radical resec tion and systemic chemotherapy.

CT Diagnosis of Intestinal Obstruction: Findings and Usefulness

PURPOSE: To present the findings of intestinal obstruction and evaluate the value of CT in the diagnosis of intestinal obstruction. MATERIALS AND METHODS: We prospectively analyzed CT scans of twenty-two patients who were suspected to have intestinal obstruction. All 22 patients were confirmed with surgery:10 patients with adhesion, four with primary intestinal tumor, one with metastatic intestinal tumor, two with inflammatory bowel disease, two with intussusception, two with extrinsic compression by ovarian tumor, and one with inguinal hernia. The CT scans were evaluated with special attention to their causes, locations, and CT findings of intestinal obstruction. CT diagnosis and findings were compared with surgical results. RESULTS: Their causes were diagnosed correctly on CT scans in seventeen of 22 cases(77.3%). Locations of the intestinal obstruction were diagnosed correctly in 16 cases(72.7% ). The CT findings of intestinal obstruction were categorized into dilated proximal bowel loops with normal distal loops, thickening of the affected bowel wall, presence of the transitional zone, and no detectable abnormalities. The associated extraluminal findings were fat infiltration around the dilated bowel loops, ascites, and mesenteric lymphnodes enlargement. There were two limitations of CT in our study:first, no detectable differences between jejunum and ileum on CT scans, and second, difficulty in differential diagnosis between thickened bowel wall mimicking normal non-dilated segment and mechanical obstruction from tumors or inflammatory bowel diseases. CONCLUSION: We conclude that CT is useful method in the evaluation of causes and locations of intestinal obstruction and the demonstration of the associated extraluminal abnormalities.

Two Cases of Triple Gastric Cancer / 대한소화기내시경학회지

Multiple gastric caner, now considered to be a sort of multiple primary cancer by Moertel's classification, is a special type of cancer in which two or more tumor lesions arise independently from the stomach. Although its incidence is rare and it has never been reported in Korea yet, the report of multiple gastric cancer is increasing with lengthened life survival and improved diagnostic method. We recently experienced two cases of triple gastric cancer, the one in 53-years-old male who had well differentiated adenocarcinoma(EGC IIb+c) on antrum, poorly differentiated adenocarcinoma on cardia and moderately differentiated adenocarcinoma on mid-body, and the other in 65-years-old female who had two poorly differentiated adenocarcinoma on cardia and anterior wall of low body and moderately differentiated adenocarcinoma (EGCIIc) on posterior wall of low body. Triple gastric cancer is rare, so we reported 2 cases of triple gastric cancer.
