Computed tomography (CT) seems to be the best imaging modality to diagnose an enterovesical fistula, but is not always able to demonstrate enterovesical fistula itself. In this case report, we present Tc-99m HMPAO white blood cell (WBC) scintigraphic findings of an enterovesical fistula complicating Crohn's disease. A 22 year-old male presented with a one-month history of urinary symptoms such as dysuria, hematuria, and frequency. The patient had intermittent right lower quadrant pain, diarrhea and hematochezia. Enterovesical fistula was highly suggestive in pelvic CT which showed air density in the urinary bladder, but cystoscopy failed to find an opening of the fistula. Tc-99m HMPAO WBC scintigraphy for evaluation of inflammatory bowel disease incidentally demonstrated enterovesical fistular tract. Crohn's disease was later confirmed by histologic examination of the surgical specimen. In our patient, Tc-99m HMPAO WBC imaging was helpful in determining the location of the fistula as well as assessing the disease activity and extent of the Crohn's disease.

Angiodysplasia is a vascular lesion of the gut, which reveals intestinal bleeding as a major symptom. It is the cause of as much as 5~6% of the intestinal bleeding of unkown origin. Pathologically, it reveals anomalous submucosal vascular overgrowth, which is characterized by tortuous, dilated and thin-walled vessels. Because the lesion is mainly submucosal. It is hard to diagnosis with endoscopy and even in laparotpmy. Angiography has a low detection rate for angiodysplasia, but some of this typical findings are delayed excretion of dye into the venous structure around the lesion, vascular tuft in the arterial phase, and accelerated dye secretion into venous structure in the situation of arteriovenous malformation. Endoscopy, especially colonoscopy is so effective a diagnostic method as to make interventional therapy. Conjugated estrogen therapy is effective and is regarded as choice of treatment in the not-life-threatening intestinal bleeding caused by angiodysplasia. Surgery is only indicated in the case of uncontrolled bleeding. Intestinal obstruction has rarely been reported as another manifestation of intestinal angiodysplasia. Therefore pathologic definition should be confirmed, and research for pathophysiology of mucosal hypertrophy in the angiodysplasia is needed.

A retrospective review was undertaken of 19 patients with occult papillary carcinoma of thyroid (lesions<1.5 cm in diameter) who were operated on at National Medical Center between 1980 and 1993. The prevalence of occult thyroid cancer was 11.7 %(19/162) of papillary cancer and 3.5 %(19/535) of all cases operated for thyroid disease. All patients were female and the mean age of patients was 45 years. Four out of 19 patients (21%) had cervical lymph node metastasis. The mean age for the group of patients with nodal metastasis was 37 years, which was more than a decade younger than the age for those without nodal metastasis, 47 years. The mean maximum diameter of the tumors was 0.72 cm with the range of 0.2 to 1.4 cm. Histologically all lesions were densely fibrotic, unencapsulated and composed of a predominantly follicular pattern. Operations were conservative. For patients with nodal metastasis, lymphadenectomy generally involved a selective node excision or a modified radical neck dissection. The mean follow-up period was 6.5 years. All patients were alive without evidence of recurrent disease and distant metastasis. Thus, radical surgical or medical extirpation of all thyroid tissue is unnecessary in the treatment of this disease.

Intussusception is a relatively common disease in children, but it is a rare clinical entity in adults. More than 80% of all patients with intussusception are less than two years of age, but adults account for only 5 to 10 percent of all intussusception cases. The significance of this disease in the aspect of statistics is mentioned as "rule of fives", which means 5% of all intussusceptions occur in adults, and it accounts for up to 5% of all cases of bowel obstruction in adults. In children, classic symptoms include episodic abdominal pain, "current-jelly" stool and a sausage-shaped abdominal mass on examination. However, in adults, it is likely to appear with non-specific gastrointestinal trouble without classic symptoms. Therefore, it is very important to use early diagnositic tool. In contrast to childhood intussusception, which is idiopathic in 90% of cases, adult intussusception has a definable lesion in more than 90% of cases 3). Tumors, both benign and malignant, are the most frequent cause of intussusecption in adults. We experienced seven cases of adult intussusception at Inha hospital from Jan. 1994 to Dec. 1997. The patients of adult intussusception are classified as three cases of ileoileal type and four ileocecal type. There were no specific signs or symptoms with patient experienced. It included abdominal pain, diarrhea and palpable mass. Their diagnosis was made in six patients using abdominal CT scan. It is difficult to define a diagnosis preoperatively, because the symptom of adult intussusception are variable and insignificant among individuals. We had been taken the final diagnostic tool with the abdominal CT scan in six of seven patients, which revealed "target lesions" in all cases. So, it is useful in the diagnosis of adult intussusception. Bowels were resected for the treatment of adult intussusception. The extent of the resection was contained the lesion and the defunctioned segments. The operations were performed as four segmental resections of small bowel and three ileocecal resections. The pathological findings were disclosed as three tumors, three lymphadenopathies and a adhesion of bowel. We concluded that the abdominal CT scanning is a usefull diagnostic tool in the diagnosis of adult intussusception.

PURPOSE: In surgical treatment for the elderly patients with the acute abdomen, the high morbidity and mortality rate become a serious problem because of the difficulty of the initial diagnosis. This study, therefore, aims at analyzing the clinical presentation of the elderly patients with the acute abdomen in order to reduce the high mortality rate for the elderly patients. METHODS: This study included 114 elderly patients who underwent the emergency operation due to the acute abdomen from May 2000 to May 2002. The age of the elderly patients was over 65 years old. The clinical characteristics of these patients were investigated retrospectively in this study. RESULTS: The most two common diseases were the acute appendicitis(25.4%) and the acute cholecystitis (21.9%) for the elderly patients. Then comes the intestinal obstruction, the gastrointestinal cancer, the colonic diverticulitis, and the gastrointestinal vascular disease in that order. The accuracy of the initial diagnosis was 79%, but the correlation between the accuracy and age significantly decreased as the age of the elderly patients increased. The postoperative complication rate was 26.3%, and the most common cause of the complications was the postoperative infection. The postoperative mortality rate was 11.4%, and the common causes of the death were the sepsis(61.5%), the postoperative bleeding, the acute renal failure, and the cardiovascular disease in order of frequency. It was found that there was a significant correlation between the complication rate and old age(p=0.021). In addition, there was a significant correla- tion between the mortality rate and old age p=0.012). CONCLUSION: In this study, it was found that the acute appendicitis and the cholecystitis were the common diseases for the elderly patients with the acute abdomen. The accuracy of the initial diagnosis was 79%; however, it decreased with the aging process. For aged people, that caused the increase of the complication and the mortality rate. It thus appears that elderly patients with the acute abdomen should be treated carefully and systematically.

Retroperitoneal fibrosis is a slowly progressing syndrome that is a part of a systemic fibrosing disease. Most causes are idiopathic, whereas the remainder are associated with methysergide ingestion, malignancy, or aneurysm of abdominal aorta. The pathogenesis is unclear, but the evidences supporting systemic autoimmune process are present, i.e. the apprearance of autoimmune antibodies, especially antinuclear antibody, positive direct or indirect Coombs' test, and the association with immune thrombocytopenia. Effective treatment with corticosteroid is another suggestion of autoimmune nature of this disease. We experienced a case of retroperitoneal fibrosis with immune thrombocytopenic purpura and positive antinuclear antibody. A 44-years old man who was in splenectomy state due to immune thrombocytopenic purpura for 15 years visited us for obstructive uropathy caused by retroperitoneal fibrosis. He was treated with double J catheter insertion in both ureters, and oral medication of corticosteroid and tamoxifen. Renal failure and thrombocytopenia was improved after treatment and the retroperitoneal fibrotic mass size decreased.

PURPOSE: An increased incidence of gallstones has been widely reported in patients who had undergone a gastrectomy. But, there has been little information about the pathophysiologic mechanism for the occurrence of gallstones after gastric surgery. Many investigators have considered the cause to be decreased gallbladder motility due to vagal denervation. We observed higher increase in the incidence of gallbladder stones in patients who underwent a Billroth II gastrojejunostomy than in those who underwent a Billroth I gastrojejunostomy after radical subtotal gastrectomy. METHODS: We prospectively studied the change in the motility of the gallbladder after a gastrectomy. The gallbladder ejection fraction (EF) was compared pre- and postoperatively by using gallbladder scintigraphy with 2,6-diisopropyl-iminodiacetic acid (DISIDA). RESULTS: Twenty patients underwent a Billroth(B) I anastomosis and twelve patients underwent a B-II anastmosis after the gastrectomy. The means of the EF of the B-I group were 75.9%, 46.4%, 68.1% at the preoperative period, at 1 month and 6 months after the gastrectomy respectively. Those of B-II group were 78.2%, 45.3%, 56.3%, respectively. There was no statistically significant difference of EF between the two groups at postoperative 1 month, but the difference at postoperative 6months was statistically significant. The differences of EF between preoperative period and postoperative 1 month, 6 months were significant in the B-I group andthe B-II group. CONCLUSION: At 6 months postoperative period, there was more recovered gallbladder motility after a gastrectomy with B-I anastomosis than with B-II anastomosis.

PURPOSE: The first Korean national population- based cancer registry using nationwide hospital-based recording system and the regional cancer registries provided the source to obtain national cancer incidences for the period 1999~2001. MATERIALS AND METHODS: The incidence of cancer in Korea was calculated based on the Korea Central Cancer Registry database, data from additional medical record review survey, the Regional Cancer Registry databases, site-specific cancer registry databases, and cancer mortality data from the Korea National Statistical Office. Crude and age-standardized rates were calculated by sex for 18 age groups. RESULTS: The overall crude incidence rates (CR) were 247.3 and 188.3 per 100, 000 for men and women and the overall age-standardized incidence rates (ASR) were 281.2 and 160.3 per 100, 000, respectively. Among men, five leading primary cancer sites were stomach (CR 58.6, ASR 65.6), lung (CR 42.1, ASR 50.9), liver (CR 41.9, ASR 44.9), colon and rectum (CR 24.2, ASR 27.3) and bladder (CR 7.7, ASR 9.2). Among women, the most common cancers were stomach (CR 30.8, ASR 25.8), breast (CR 25.7, ASR 21.7), colon and rectum (CR 19.6, ASR 16.7), uterine cervix (CR 18.4, ASR 15.5), and lung cancer (CR 15.1, ASR 12.4). In 0~14 age group, leukemia was most common for both sexes. For men, stomach cancer was most common in 15~64 age group, but lung cancer was more frequent for over 65 age group. For women, thyroid cancer in 15~34 age group, breast cancer in 35~64 age group, and stomach cancer in over 65 age group were most common for each age group. The proportions of death certificate only were 7.5% for men and 7.4% for women. CONCLUSION: This is the first attempt to determine the national cancer incidence and this data will be useful to plan for research and national cancer control in Korea.
