Opacification of the gallbladder after parenteral administration of contrast material usually indicates diminished renal function but can occur with normal renal function. The authors recently experienced 13 cases of such vicarious excretion of contrast media. Among 13 patients. 9 patients had renal disease unilateral ureteral stone(n=3), staghorn calculi(n=2), acute renal failure from sepsis(n=1), renal contusion(n=2) and unilateral renal artery involvement by dissecting aortic aneurysm(n=1). Of these 9 patients, 3 patients showed abnormal serum creatinine levels at the time of presentation or shortly thereafter. In 6 patients, injection of a large amount of contrast media was possibly the additional cause of vicarius excretion. There was no detectable cause in the remaining 4 patients. Heterotopic excretion of contrast media is clearly a complex phenomenon, the reason for which it is difficult to establish with certainty in each individual case. Anyhow, vicarius excretion of contrast media occurs more frequently than previously thought, and it can occur not only with abnormal renal function but with normal function also.

OBJECTIVES: Recurrent mucosal disease and anatomic obstruction are commonly cited causes of failed endoscopic sinus surgery (ESS). Hyaluronic acid (HA) has been reported to reduce scarring and to promote wound healing in sinonasal surgery. HyFence is HA stabilized by 1, 4-butandiol diglycidyl ether, which makes it less-water-soluble and highly viscoelastic. The purpose of this study is to examine the anti-adhesion effect of HyFence after ESS compared to that of HA-CMC (Guardix-Sol). METHODS: Seventy-four patients with chronic rhinosinusitis who underwent ESS were included in the study. After the ESS procedure, Merocel was placed in the ethmoidectomized areas of the both sides. Five milliliters of Guardix-Sol was then applied to the Merocel of one side and HyFence LV was applied to the other side. The effect of the agents was evaluated at one, two, and four weeks after surgery by endoscopic examination. The severity of adhesion, edema, infection and complications were evaluated. RESULTS: There was no significant difference in the incidence of postoperative adhesion between the HyFence group and the Guardix-Sol group (P>0.05). Mean postoperative grades of edema and infection showed no significant difference between groups (P>0.05). There was no significant postoperative complications associated with either anti-adhesion agent (P>0.05). CONCLUSION: HyFence has equivalent anti-adhesion effect compared to Guardix-Sol following ESS.

To assess the result of radiation therapy for fifteen years experience, a total of 81 cases of pathologically proven vocal cord cancer had been analysed according to patient survival retrospectively. All the patients had been treated with radiation therapy using Co-0 teleherapy unit in curative aim. The results are as follows ; 1. According to AJCC staging, five year survival rate was 75.0% in stage I, 73.1% in stage II, 36.0% in stage III, and 20.0% in stage IV. 2. According to T-taging, five year survival rate was 75.0% in T1, 73.1% in T2, 24.3% in T3, and 25.0% in T4. 3. According to nodal status, five year survival rate was 59.4% in negative node group and 14.2% in positive group. 4. According to the histologic grade, the better in differentiation, the more in number of cases and the better in prognosis. 5. In summary, five year actuarial survival rate was 55.5% and ten year survival rate was 49.8% and ten year survivors totalled 12 cases.

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.

Retrospective analysis of survival rates was undertaken in the patients of 58 cases treated with conventional radiation therapy for malignant salivary gland tumors between January 1975 and December 1984 in Korea Cancer Center Hospital (KCCH). They were patients whose long-term follow-up was possible and who had refused surgery or had had recurrences postoperatively. Out of 58 patients, 25 patients (43.1%) had mucoepidermoid carcinomas and 24 patients (41.3%) adenoid cystic carcinoma. Total actuarial survival rates at 5 years and 10 years were 68.2% and 31.8% respectively, but disease-free survival rates, 43.2% and 13.0%, respectively. According to TNM stage, the survival rates at 5 years were 86.5% in T1, 40.0% in T2 + T3, and 0% in T4. In terms of histologic types, 5 years disease-free survival rate of adenoid cystic carcinomas (40.1%) was lower than that of mucoepidermoid carcinomas (49.8%) but overall survival rate (77.3%) was much higher than that of mucoepidermoid carcinomas (51.5%). Therefore, we concluded that the patients, who had had disease after failure of treatment, could survive during a certain period of time and their alive times were 2 years on the average. There was a difference in survival rates in the mucoepidermoid carcinomas in terms of histological grade of differentiation and it was a arbiter in prognosis: 5 YSR of low-grade was 78.8% and higher 2 times than that of high-grade. There was no difference in survival rates according to location and sex. The number of patients having minor salivary gland tumors was 6 cases and their actuarial 5 YSR was 32.3%. Consequently, prognostic factors which influence the survival rates of patients with malignant salivary gland tumors are thought to be 1) histological ubtypes 2) T and N staging (AJCC) 3) histological grade, especially in mucoepidermoids.

Total of 154 patients of pathologically proven and previously untreated nasopharyngeal carcinoma who were treated in the Department of Therapeutic Radiology, Korea Cancer Center Hospital during the period from 1964 to 1984 were analyzed. Minimal follow-up period of survivors was 3 years. Thirteen percent of the patients had T4 primary lesions and 65% had stage IV disease. Total radiation dose to the primary site was 1550~1750 ret in 82 and above 1750 ret in 72 patients. Local control was obtained in 79% of patients. Significant prognostic factors for the survival were tumor dose (above vs. below 1750 ret), age (below vs. above 30 years), stage (AJCC I-III vs IV), T stage (T1 vs. T2-4), and N stage (NO vs. N+).

Tonsillectomy, with or without adenoidectomy, remains the most frequently performed surgical procedure by otolaryngologists. Postoperative hemorrhage, which is classified as primary (<24 h) or secondary (>24 h) hemorrhage, is recognized as a rare but potentially life-threatening complication. Although most oral bleedings occuring after tonsillectomy are considered as post-tonsillectomy hemorrhages, there could also be other origins such as gastrointestinal hemorrhage. We recently experienced a case of gastrointestinal hemorrhage that was misdiagnosed as secondary post-tonsillectomy hemorrhage. We report this case with a review of the literature.

PURPOSE: The purpose of this study is to evaluate the usefulness of locally harvested bone in anterior cervical interbody fusion. MATERIALS AND METHODS: A retrospective review was conducted, including 31 patients who underwent anterior cervical interbody fusion using a polyetheretherketone (PEEK) cage and anterior plate fixation. We randomly divided the patients into two groups, local bone group and iliac bone group. In 15 patients of the local bone group, the cage was filled with locally harvested bone, and in another 16 patients of the iliac bone group, the cage was filled with autogenous iliac bone. RESULTS: Improvements in mean visual analogue scale (VAS) scores, from 5.8 and 7.7 to 1.6 and 2.3 for neck pain and arm pain, respectively, were observed in cases using locally harvested bone, while the improvements were from 5.7 and 7.2 to 1.4 and 2.2, respectively, in those using autogenous iliac bone grafts. However, no significant differences in mean VAS and neck disability index were observed between the two groups at the last follow up (p>0.05). Radiologic union was achieved at 14.0+/-2.50 weeks in the local bone group, and at 12.62+/-1.58 weeks in the iliac bone group. However, no significant difference was observed between the two groups (p=0.076). CONCLUSION: Utilization of locally harvested bone for packing in a PEEK cage for anterior cervical interbody fusion is considered a useful method because it gives satisfactory clinical results for retention of bone union and lordosis angles.

Korean Journal of Otolaryngology - Head and Neck Surgery 2011;54(5):344-346
Spontaneous tonsillar hemorrhage (STH) is an extremely rare event. Usually, the causes of STH are ascribed to vessel wall erosion secondary to bacterial or viral infection of tonsils. Other causes include vascular or tumorous lesions around tonsil, coagulation disorders and idiopathic one. On one hand, the total number of reported STH has slightly increased because STH is defined as all forms of "bleeding tonsils", including even minor bleeding. On the other hand, the portion of the total STH that is life-threatening has become relatively few. Management of STH involves the use of antibiotics, and early tonsillectomy is recommended. We have experienced a case of a 29 year-old female with tonsillar hemorrhage in the absence of any identifiable cause. We report the case with a review of the related literatures.
