Bronchoesophageal fistula is a rare clinical entity whether congenital or acquired in adult. We experinced 8 cases of bronchoesophageal fistula and performed surgical correction from 1991 to 1994. Of the 8 patients, 5 patients were male and three were female aging from 21 to 61 years(mean 44.12$\pm$14.62 years). Seven of 8 patients had congenital bronchesophageal fistula and the other one had acquired bronchoesophageal fistula. According to the classification of Braimbridge and Keith, 4 cases were belonged to type I and 3 cases were type II . The diagnosis was confirmed by esophagogram in six patients, by bronchoscopy and bronchogram in two patients, and in one patient, the fistula was discovered i cidentally during operation. All patients received astulectomy and concomitant procedures were applied as follows ; 4 diverticulectomy, 4 right lower lobectomy, 1 bilobectomy, 1 left lower lobectomy and 1 wedge resection of left lower lobe. All but one patient were discharged without any complication and have been in good condition.

62-year-old patient who had past history of endoscopic submucosal dissection for early gastric cancer at September 2008, underwent endoscopic submucosal dissection of esophagus for early esophageal cancer at mid esophagus during health screening service. Because there was a high risk of lymph node metastasis at biopsy results, concurrent chemoradiotherapy was added to endoscopic submucosal dissection. There was a metachronous cancer at mid-esophagus at March 2013. He underwent endoscopic mucosal resection and photodynamic therapy. Concurrentchemoradiotherapy after endoscopic submucosal dissection is an effective treatment method.

We report our experience with a case of performing laparoscopy-assisted total gastrectomy along with pancreas-preserving splenectomy for treating early gastric cancer. laparoscopy-assisted total gastrectomy was planned for a 62-year-old male patient with a double early gastric cancer located in the upper and lower third of the stomach. Five trocars were placed and we used a harmonic scalpel to dissect the greater curvature. Enlarged splenic hilar lymph node was encountered and they were proved to be metastasis by frozen section biopsy. We then performed total gastrectomy with pancreas-preserving splenectomy for the purpose of completely dissecting the lymph nodes along the splenic artery and splenic hilum. We created a 4 cm sized longitudinal mini-laparotomy below the xiphoid process to remove the specimen, and anastomosis was done via the Roux-en-Y method. The patient was discharged on the 9th postoperative days after an uneventful recovery. Our experience shows that laparoscopy-assisted total gastrectomy with pancreas-preserving splenectomy is a relatively safe procedure for treating upper third early gastric cancer with metastatic splenic hilar lymph nodes.

Purpose : This study was performed to know the clinical profile and effectiveness of colonoscopic polypectomy in patients with solitary juvenile polyp. Methods : This study included 19 children, aged 1.8 to 11.4 years, who underwent colonoscopic polypectomy and histologically proven solitary juvenile polyps between March 1998 and August 2002. We analyzed their detailed history, clinical manifestations, colonoscopic examination, method of anesthesia and results of colonoscopic polypectomy. Results : The mean age of the 19 cases was $4.7{\pm}2.8year$. The male to female ratio was 1 : 1.1. Hematochezia, the main indication of colonoscopy, was present in all cases. Combined symptoms were mucoid stool or diarrhea(42%), abdominal pain(26%), constipation(11%) and anal fissure(11%). Anemia(Hb <10 g/dL) in four cases recovered spontaneously after polypectomy. Complications associated with premedication, sedation and colonoscopy itself did not occur. Bleeding developed in two cases(11%) after polypectomy. One of them was controlled with hemoclipping. The main site of polyps was the rectosigmoid colon in 15 cases(79%). The size of the polyps ranged from 0.5 to 3.5 cm. The interval between the onset of symptoms and polypectomy was from 0.1 to 42 months. Conclusion : Juvenile polyps are a common cause of benign, chronic and recurrent rectal bleeding. Colonoscopic polypectomy is a simple, safe and effective therapeutic method. So earlier colonoscopy might avoid uneffective treatment and prevent untoward problems such as fear of parents and anemia.

Purpose: This study was performed to evaluate the usefulness of computed tomography (CT) gastrography in the surgical management of a gastric gastrointestinal stromal tumor (GIST). Materials and Methods: We retrospectively analyzed the clinicopathologic data of 38 patients who had undergone CT gastrography from among patients who had gastric GISTS surgically resected at the Department of Surgery, Seoul National University Hospital, between January 2001 and February 2006. We compared CT gastrography data, including tumor size and location and distance from the gastroesophageal junction or pylorus with endoscopic, surgical and pathologic findings. Results: The longitudinal tumor locations on CT gastrography and endoscopy were identical to the surgical findings. For tumor sizes on CT gastrography of less than 5 cm, we performed 11 (42.3%) laparoscopic wedge resections from among 26 cases. In the 12 cases with tumor sizes of 5 cm or over, only 1 (8.3%) laparoscopic wedge resection was performed. When the tumor was located in the middle third of the stomach, a laparoscopic wedge resection was performed in 88.9% (8/9) of the cases, but when it was located in the upper or lower third, a laparoscopic wedge resection was performed in only 13.8% (4/29) of the cases. Conclusion: Three-dimensional information from CT gastrography allows the surgeon to perform preoperative planning, including accurate localization.

Necrotizing bronchial aspergillosis usually occurs in the immumocompromised host. Aspergillus invades bronchial epithelium and forms endobronchial mass or endobronchial stenosis. A 78-year-old male patient with diabetus mellitus complaining of dyspnea and cough was admitted to our hospital. Plain chest X-ray and chest computed tomogram showed a large endobronchial mass and total collapse of left upper lobe of the lung. Bronchoscopic biopsy of the endobronchial mass revealed chronic inflammation. To confirm the endobronchial mass, we performed sleeve lobectomy of left upper lobe of the lung. Histologically the mass was diagnosed as necrotizing bronchial aspergillosis. We report a case of necrotizing bronchial aspergillosis in an elderly man who has diabetus mellitus with review of the literature.

Purpose: Laparoscopic gastric resection (LGR) is increasingly being used instead of open gastric resection (OGR) as the standard surgical treatment for gastric submucosal tumors. Yet there are few reports on which technique shows better postoperative outcomes. This study was performed to compare these two treatment modalities for gastric submucosal tumors by evaluating the postoperative outcomes. We also provide an analysis of the learning curve for LGR. Materials and Methods: Between 2003.4 and 2008.8, 103 patients with a gastric submucosal tumor underwent either LGR (N=78) or OGR (n=25). A retrospective review was performed on a prospectively obtained database of 103 patients. We reviewed the data with regard to the operative time, the blood loss during the operation, the time to the first soft diet, the postoperative hospital stay, the tumor size and the tumor location. Results: The clinicopatholgic and tumor characteristics of the patients were similar for both groups. There was no open conversion in the LGR group. The mean operation time and the bleeding loss were not different between the LGR group and the OWR group. The time to first soft diet (3.27 vs. 6.16 days, P<0.001) and the length of the postoperative hospital stay (7.37 vs. 8.88 days, P=0.002) were shorter in the LGR group compared to the OGR group. The tumor size was bigger in the OGR group than that in the LGR group (6.44 vs. 3.65 cm, P<0.001). When performing laparoscopic gastric resection of gastric SMT, the surgeon was able to decrease the operation time and bleeding loss with gaining more experience. We separated the total cases into 3 periods to compare the operation time, the bleeding losses and the complications. The third period showed the shortest operation time, the least bleeding loss and the fewest complications. Conclusion: LGR for treating a gastric submucosal tumor was superior to OGR in terms of the postoperative outcomes. An operator needs some experience to perform a complete laparoscopic gastric resection. Laparoscopic resection could be considered the first-line treatment for gastric submucosal tumors.

Endobronchial chondroma is a cartilaginous benign tumor, which arises from bronchial cartilage. As a rare benign tumor, endobronchial chondroma differs from cartilaginous hamartoma in that it includes cartilage components only, but hamartoma contains lipomatous and lymphoid tissue. The clinical manifestations of endobronchial chondroma are associated with the extent of mechanical obstruction of bronchus. Symptoms of endobronchial chondroma are nonspecific, such as cough, sputum, fever, or dyspnea on exertion. Endobronchial chondroma is often misdiagnosed as other diseases, such as asthma, chronic obstructive pulmonary disease, or pulmonary tuberculosis. The treatment is usually surgical procedures, such as resection of lung segment or lobe by thoracostomy, or resection of tumor by bronchoscopy. We report a case of the patient who was diagnosed to have endobronchial chondroma treated by bronchial resection and end to end anastomosis.

In comparison to parenchymal hamartoma, endobronchial hamartoma is rare benign neoplasm of the lung. Most parenchymal hamariomas are asymptomatic and are found incidentally. However, endobronchial hamartomas are frequently discovered through respiratory symptoms as a result of bronchial irritation or obstruction. A 47-year-old male patient was admitted to our hospital due to dry cough f month prior to admission. On bronchoscopic examination, a polypoid mass was found completely obliterating the anterior segmental bronchus of the left upper lobe. We report a case of endobronchial chondroid hamartoma, which was resected by anterior segmentectomy of the left upper lobe.
