A 72-year-old man with progressive, unexplained lower gastrointestinal bleeding presented to the emergency department with abdominal pain and shock. Computed tomography of the abdomen showed a fistula between a right common iliac artery aneurysm and the small intestine. Laparotomy demonstrated a saccular aneurysm of the common iliac artery with a fistulous communication to the terminal ileum. Aneurysmectomy, aortoiliac graft replacement and segmental ileocecal resection with end-to-side anastomosis were all successfully performed. For a patient having an arterioenteric fistula along with lower gastrointestinal bleeding, making an early diagnosis using computed tomography and then performing immediate surgery can be expected to save the patient's life.

Meckel's diverticulum (MD) occurs in approximately 2 % of the population. The major complications of MD are bleeding, intestinal obstruction, infection and perforation. Perforation is the least common but most serious complication, the incidence od which is about 5-10 %. The causes of perforation are inflammatory diverticulitis and peptie ulceration. the purpose of study is to review the characteristics of perforated MD in children. Six patients with perforated MD who had been operated upon at the Department of Pediatric Surgery, Yeungnam University Hospital from April 1984 to July 2001 were included. Male predominated in a ratio of 5:1 and there were 2 neonates. The chief complaints were abdominal pain and distension. Half of the children showed a past history of bloody stools. The average age was 4 year and 9 months. The mean distance from the ileocecal valve to the diverticulum was 60 cm. Average length of the diverticulum was approximately 3 cm and width was 1.7 cm. The perforation site was the tip of the diverticulum in 3 cases, the base in 2 cases and along the lateral border in one. In two patients, ectopic gastric mucosa was found in the specimen. All of the patients were operated upon with a diagnosis of peritonitis of unknown etiology. In conclusion, when a child shows symptoms of acute abdomen or peritonitis, especially in boys, with the history of bloody stools and episodic abdominal pain, perforated MD should be suspected.

The purpose of this study is to review the operative management and outcome of operation for Crohn's disease. The medical records of 17 patients who underwent operations for Crohn's disease at Seoul National University Children's Hospital from January of 1988 to June of 2005 were reviewed. The male-to -female ratio was 1.8: 1. The median age at the onset of symptoms and the time of diagnosis was 9 years 6 months and 11 years 6 months respectively. The median time interval from diagnosis to operation was 2 years and 1 month (0 month~8 years). The ileocolic or ileocecal region was the most common site of involvement. The indications for operation were intractable symptoms (8 cases) and obstruction or stricture (7 cases). The median postoperative hospitalized days were 14.4 days (8~35 days). Five patients (29 %) experienced postoperative complications. Symptom free state or symptom relief was observed in 11 cases after surgery and 6 cases had intermittent episodes of remissions and recurrences. In pediatric Crohn's disease patients who present with intractable symptoms despite medical treatment or develop surgical complications, symptom free state or symptom relief can be achieved by minimal resection of the diseased segment.

Anti-mutagenic and anti-septic effects of $\beta$-1,3/1,6-glucan from Aureobasidium pullulans SM-2001 were evaluated on the on the cyclophosphamide (CPA)-cecal ligation puncture (CLP) and CPA-treated mice. To induce immunosuppression and mutagenicity, 150 and 110 mg/kg of CPA were single intraperitoneally injected at 3 or 1 day before CLP or initial $\beta$-glucan administration. In CLP animals, the cecum was mobilized and ligated below the ileocecal valve, punctured through both surfaces twice with a 22-gauge needle. 125 mg/kg of $\beta$-glucan were dissolved in saline and subcutaneously or orally administered in a volume of 10 ml/kg (of body weight), 4 times, 12 hrs intervals from 6 hrs after CLP or 1 day after second dose of CPA. After treatment of $\beta$-glucan, the mortalities were observed in CPA-CLP model, and the appearance of a micronucleus is used as an index for genotoxic potential in CPA model. As results of CPA-CLP sepsis, all animals (9/9, 100%) in CPA-CLP control were dead within 2 days after CLP. In addition, increase of the number of bone marrow MNPCEs indicated mutagenicity were also observed by treatment of CPA. However, $\beta$-glucan treatment effectively inhibited the mortalities in CPA-CLP, and it also reduced the CPA treatment-related mutagenicity, respectively. These results indicated that $\beta$-glucan has effective anti-septic and anti-mutagenic effects and can be used as an agents for treating sepsis and mutagenicity related to high-dose chemotherapy or radiotherapy. However, further studies should be conducted to observe more detail action mechanisms of it's anti-septic and anti-mutagenic effects.

Objectives This study was conducted to confirm anatomical information near the treatment areas of visceral chuna manual therapy and to secure stability and effectiveness during the treatment. Methods For 50 healthy adult men and women, a total of 13 ultrasound images were taken of the 7 treatment areas which are the representative treatment areas of visceral Chuna manual therapy. Results The treatment area of the bottom of the liver can be palpated around the right side ST19 and CV14. The treatment area of the gallbladder and the common bile duct can be palpated around the right side SP16 and ST20. The treatment area of the cardia and the pylorus can be palpated around the left side KI21, right side ST20, ST21, KI19, KI20, CV12, and CV13. The origin point of the mesentery root can be moved to the left and lower left from CV12 and can be palpated. The treatment area of the ileocecal valve and the cecum can be palpated around the right side SP14. The treatment area for the colic flexure can be palpated around the both side LR13. The treatment support point for the kidneys can be palpated around both side BL51. Conclusions It is thought that if the ultrasound image data from the meridians around the treatment site is used as an auxiliary, it will be more effective in terms of safety and effectiveness during the treatment of visceral Chuna manual therapy.

Disseminated tuberculosis (TB), resulting from the hematogenous spread of tubercle bacilli, typically affects immunocompromised individuals, such as those infected with the human immunodeficiency virus. However, risk factors in immunocompetent populations are not well understood. Here, we report a rare case of disseminated TB with CD4+ T-cell depletion in a previously healthy 35-year-old man. The patient presented with a 2-month history of intermittent gross hematuria, dysuria, loose stools, and weight loss. His medical history was unremarkable except for a herpes zoster infection 4 years prior to presentation. Laboratory tests revealed microscopic hematuria and pyuria; however, the urine culture was negative. Urine specimens tested positive for TB-polymerase chain reaction. Abdominal computed tomography revealed a focal filling defect in the left kidney, segmental wall thickening of the terminal ileum, and multiple enlarged lymph nodes with central necrosis. Chest computed tomography revealed active pulmonary TB. Colonoscopy confirmed intestinal TB in the terminal ileum and ileocecal valve, with positive TB-polymerase chain reaction results from sputum and ileal ulcer tissue. The patient was diagnosed with disseminated TB and was treated with standard anti-TB drugs. Although the human immunodeficiency virus test results were negative, the patient's CD4+ T-cell count was significantly low (278/μL). Follow-up tests after 1 month showed negative TB cultures; however, the patient's CD4+ T-cell depletion persisted, with counts remaining low after 1 year. This case highlights the rare occurrence of disseminated TB in immunocompetent individuals with CD4+ T-cell depletion and emphasizes the importance of CD4+ T-cell assessment in healthy patients presenting with disseminated TB.

Purpose: Mecnoium obstruction in very low birth weight infants (VLBWI), which delays enteral feeding and is one of the major causes of bowel obstruction, can be diagnosed and treated with hyperosmolar water-soluble contrast enema. The purpose of this study was to observe the clinical findings of meconium obstruction, the improvement of small bowel obstruction after contrast enema, and the complications related to the enema. Methods: Hypersolmolar water-soluble contrast enemas were performed in 14 VLBWIs with meconium obstruction. Clinical findings, radiologic findings, feeding intolerance, effectiveness, and complications of enemas were observed. Also, clinical findings related to meconium obstruction were compared with 18 VLBWIs without meconium obstruction. Results: 1) Fourteen VLBWIs with meconium obstruction had significantly lower 5 minutes Apgar scores than 18 VLBWIs without meconium obstruction (p<0.05). Moreover, the day of last meconium passing, and the day of the first trial and full enteral feeding were delayed significantly. 2) A total of 18 enemas were performed in the 14 infants. The contrast medium passed the ileocecal valve and reached the terminal ileus in 12 enemas. Of the 12 enemas, 11 were successful, but 1 infant underwent an ileotomy, even though the contrast medium reached the terminal ileum. 3) Intestinal obstruction was not relieved in three of five infants, in whom the contrast medium failed to pass the ileocecal valve. Obstruction was relieved after repeated enemas in which the contrast medium reached the terminal ileum. 4) No complications associated with water-soluble contrast enemas were observed. Conclusion: Hyperosmolar water-soluble contrast enema is considered to be safe and therapeutic for meconium obstruction in VLBWIs.

Purpose : Although air enema reduction has been known as a good method of diagnosis and treatment of intussusception, it could develop colon perforation. However, there have been few studies about this complication. So we analyzed the risk factors of colon perforation during air enema reduction in patients with intussusception. Methods : We reviewed the charts of 12 colon perforation patients during air enema reduction of intussusception, who were admitted to Gil Medical Center from Jan. 1990 to Dec. 2001. Their age, sex, major symptoms, length of time till hospital visit, types of intussusception, operative findings and pathologic reports were reviewed. Results : Among 657 cases, 596 patients(90.7%) were successfully treated, but 12 patients(1.83%) failed in air enema reduction and had colon perforation. In patients with colon perforation the male to female ratio was 11 : 1, and average age was 5.3 months. The most common symptom at the time of hospital visit was vomiting(91.7%). Cyclic irritability(75.0%), bloody stool(75.0%) and abdominal mass(41.7%) were also noted. The average length of time between symptom onset and hospital visit was 44.7 hours. Types of intussusception were predominantly ileocolic, ileocecal, and ileoileocolic. The site of perforation was most commonly found at the proximal part of intussusception including ascending colon(50%) and transverse colon(50%). Most cases were uncomplicated, and had a single perforation. Pathologic reports showed hemorrhagic necrosis and mesenteric laceration at the site of colon perforation. Complications of colon perforation were tension pneumoperitonium(58.3%), requiring immediate decompression. Conclusion : The chance of colon perforation during air enema reduction increases in cases with small bowel obstruction on simple abdominal x-ray of a patient younger than 6 months, delay in time till hospital visit and higher air pressure during reduction. Therefore more careful investigation is needed in these cases.

Purpose: Ingested foreign bodies present a common clinical problem. It is well known that most of them pass uninterrupted through the gastrointestinal tract. We evaluated the role of endoscopy and Foley catheter for removal of foreign bodies in the gastrointestinal tract. Methods: We investigated retrospectively 60 cases with foreign bodies in the gastrointestinal tract. They had been treated at Wonju Christian Hospital, Yonsei University of Korea, from January, 1996 through December, 1999. Results: The age of the patients ranged from 7 months to 13 years. Patients under 5 years were 57 cases (97%) and there was no significant difference in sex (M : F=1.07 : 1). 45 cases of the patients had no symptom. The most common foreign bodies were coins (43 cases). The most common location was esophagus (31 cases). The number of foreign body removal using flexible endoscopy and Foley catheter was 22 (36.7%) and 18 (30.0%) cases, respectively. In 18 cases (30.0%), foreign bodies passed spontaneously. Only 1 case (1.7%), curtain pin impaction at ileocecal region, required surgery. Conclusion: Early foreign body removal from esophagus and stomach is recommended to lessen the morbidity and complication. Fluoroscopic foley catheter technique and flexible endoscopy for removal of esophageal foreign bodies in children is safe and effective.

Since the performance of deep learning techniques has recently been proven in the field of image processing, there are many attempts to perform classification, analysis, and detection of images using such techniques in various fields. Among them, the expectation of medical image analysis software, which can serve as a medical diagnostic assistant, is increasing. In this study, we are attention to the capsule endoscope image, which has a large data set and takes a long time to judge. The purpose of this paper is to distinguish the gastrointestinal landmarks and to estimate the gastrointestinal transition location that are common to all patients in the judging of capsule endoscopy and take a lot of time. To do this, we designed CNN-based Classifier that can identify gastrointestinal landmarks, and used it to estimate the gastrointestinal transition location by filtering the results. Then, we estimate gastrointestinal transition location about seven of eight patients entered the suspected gastrointestinal transition area. In the case of change from the stomach to the small intestine(pylorus), and change from the small intestine to the large intestine(ileocecal valve), we can check all eight patients were found to be in the suspected gastrointestinal transition area. we can found suspected gastrointestinal transition area in the range of 100 frames, and if the reader plays images at 10 frames per second, the gastrointestinal transition could be found in 10 seconds.
