Aortoesophageal fistula is an uncommon and fatal complication after surgery of aortic aneurysm. A case of aortoesophageal fistula as a complication of synthetis patch aortoplasty for mycotic aneurysm of descending thoracic aorta is described. After 3 months since patch aortoplasty for mycotic aneurysm of descending thoracic aorta this patient visited the emergency room due to melena and hematemesis. After gastrofiberoscopy and computed tomography the patient was taken ot the operating room. The surgical intervention was performed in two steps. Median sternotomy and midline laparotomy were made. Hemashield's Dacron(16mm) bypass between ascending thoracic aorta and infra-renal abdominal aorta was established first. Through the posterolateral thoracotomy false aneurysm and previous Hemashield's Dacron patch of descending aorta were resected. The two ends of the aorta were sutured and esophageal fistula was repaired. The esophageal suture line and the stumps were covered with omental graft. Thirty months later the patient has had no difficulty referable to the aortic surgery.

Diaphragmatic hernia was found in a patient who had undergone transhiatal esophagectomy for early esophageal cancer. Chest X-ray was not helpful, but abdominal or chest computed tomography was useful for accurate diagnosis. Primary repair through thoracotomy was performed and was found to be feasible and effective. However, long-term follow-up is required because hernia recurrence is common.

A 61-year-old man with an antecedent febrile illness presented with progressive flaccid paraparesis, but no sensory or sphincter involvement. Magnetic resonance imaging (MRI) of the spine was negative and nerve conduction study (NCS) showed the absence of F-waves in his legs, suggesting $Guillain-Barr{\acute{e}}$ syndrome (GBS). However, abdominal pain after admission led to the consideration of the spinal cord ischemia secondary to aortic dissection confirmed by computed tomography. We report the rare condition of painless aortic dissection simulating GBS.

Ulcerative colitis (UC) is a chronic idiopathic inflammatory bowel disease. Mesalizine for the first-line therapy of UC has adverse effects include pancreatitis, pneumonia and pericarditis. UC complicated by two coexisting conditions, however, is very rare. Moreover, drug-related pulmonary toxicity is particularly rare. An 11-year-old male patient was hospitalized for recurring upper abdominal pain after meals with vomiting, hematochezia and exertional dyspnea developing at 2 weeks of mesalizine therapy for UC. The serum level of lipase was elevated. Chest X-ray and thorax computed tomography showed interstitial pneumonitis. Mesalizine was discontinued and steroid therapy was initiated. Five days after admission, symptoms were resolved and mesalizine was resumed after a drop in amylase and lipase level. Symptoms returned the following day, however, accompanied by increased the serum levels of amylase and lipase. Mesalizine was discontinued again and recurring symptoms rapidly improved.

Heterotopic pancreas (HP) is defined as pancreatic tissue lacking anatomic and vascular continuity with the main body of the pancreas. Most are asymptomatic, but can cause ulcer, bleeding, intussusception, and mechanical obstruction. Herein, we presented one case of HP presented as duodenal tumor causing duodenal obstruction. A 7-year-old girl visited the emergency room for abdominal pain with vomiting for 24 hours. Computed tomography and upper gastrointestinal series revealed a polypoid mass with short stalk in the 2nd portion of duodenum. We attempted an endoscopic removal. However, the lumen was nearly obstructed by the mass and the stalk was too broad and hard to excise. The mass was surgically removed via duodenotomy. It was confirmed as a HP with ductal and acini components (type 2 by Heinrich classification). Postoperatively, the patient has been well without any complication and recurrence.

위석은 위장관계에 흡수되지 않는 이물질들이 축적, 응고되어 점점 그 크기가 증가하여 덩어리를 이룬 것을 말하며, 위장관계 폐색을 일으키거나, 진단이 늦어져 만성 복통의 원인이 되기도 한다. 그 중 모발석의 경우는 발모벽과 모식증의 과거력이 흔히 동반된다. 저자들은 담즙성 구토와 복부 산통 때문에 방문한 8세 여아에서 진단된 소장의 모발석 1예를 경험하여 문헌 고찰과 함께 보고한다.

We report a case of hepatoma which had a suggested splenic metastasis in a 64 year-old male patient. Hepatoma proved by abdominal CT (Computed Tomography) and considerable accumulation of $^{99m}Tc$-DISIDA was noted in a enlarged spleen. We suggests the splenic uptake of the radionuclide corresponded to the diffuse metastasis of hepatoma to spleen.

This paper proposes an automatic liver segmentation method using improved partial histogram threshold (PHT) algorithms. This method removes neighboring abdominal organs regardless of random pixel variation of contrast enhanced CT images. Adaptive multi-modal threshold is first performed to extract a region of interest (ROI). A left PHT (LPHT) algorithm is processed to remove the pancreas, spleen, and left kidney. Then a right PHT (RPHT) algorithm is performed for eliminating the right kidney from the ROI. Finally, binary morphological filtering is processed for removing of unnecessary objects and smoothing of the ROI boundary. Ten CT slices of six patients (60 slices) were selected to evaluate the proposed method. As evaluation measures, an average normalized area and area error rate were used. From the experimental results, the proposed automatic liver segmentation method has strong similarity performance as the MSM by medical Doctor.

Spontaneous and isolated dissection of the limb arteries without involvement of the aorta is extremely rare, and has been reported previously in pregnant patients in association with collagen vascular disease, and in cases of high-energy trauma or intensive activity in athletes. There is no consensus yet on indications for medical or surgical therapeutic modality. Due to the rarity of spontaneous dissection of external iliac artery, its natural history has been poorly described. A healthy 50-year-old male with normotension was admitted with an acute onset of left flank pain. Left external iliac artery dissection was diagnosed by abdominal computed tomography.

We report a case of a 13-year-old girl who presented with a 2-month history of intermittent abdominal pain. Laboratory examination showed hepatitis and pancreatitis. Because of persistent vomiting, computed tomography (CT) was performed, which revealed a circumferential soft tissue density in the duodenal wall, causing partial obstruction. Supportive therapy failed. Repeat CT showed no significant change from the initial study. The patient underwent upper endoscopy, which revealed a mass in the second portion of the duodenum, which occluded most parts of the lumen. The histopathological finding was consistent with an anaplastic large cell lymphoma, a rare form of small bowel neoplasm. After the third course of chemotherapy, complete resolution of the mass was noted, and her symptoms were relieved.
