피열연골절제술 (arytenoidectomy)은 양측성대마비 환자의 호흡곤란을 해결하기 위한 방법의 하나로서 현재까지 사용되고 있으며, 술식을 대별하면 Woodman등이 시행한 extralaryngeal approach방법과 Thornell등이 시도한 내시경적 피열연골 절제술로 나눌 수 있다. 최근에는 $CO_2$레이저에 의한 내시경적 피열연골절제술이 각광을 받고 있는데 그 장점으로는 첫째, 수술방법이 쉽고, 둘째, 수술시 출혈이 적으며, 세째, 병변부에 기구를 직접 접촉시키지 않고 수술할 수 있어 수술시야를 방해받지 않으며, 네째, 술후 육아조직 발생이 적고, 다섯째, 국소염증 반응이 적어 치유가 빠르다는 점 등이라 할 수 있다. 저자들은 최근 여러 원인에 의해 발생된 양측 성대마비 환자 3례에서 coherent $CO_2$레이저를 이용한 내시경적 피열연골절제술을 시행하여 그 경과가 좋았기에 문헌고찰과 함께 보고하는 바이다.

A 42-year-old female was referred to our department after find out submucosal tumor type lesion on cardia at local clinics. She experienced no specific symptom. On gastroscopy, two distinct neoplasms were detected. One of which was located in the cardia anterior wall of the stomach with the size of 2.0×1.1 cm, and the other one was localized in the cardia posterior wall of the stomach and its size was 1.5×1.2 cm. We performed endoscopic submucosal dissection. Pathological evaluation revealed the diagnosis of gastrointestinal stromal tumor (GIST) at the cardia anterior wall and malignant lymphoma from the mass localized cardia posterior wall of the stomach. We would like to report these rare synchronous tumors which were successfully treated by endoscopic resection in the same patient

Simple bone cysts are common, benign bone tumor and for the treatment, curettage with bone grafting, resection and intralesional steroid or autogenic bone marrow injections were usually performed. Simple bone cysts of the calcaneus are relatively uncommon and curettage with autologous bone grafting were proposed for management rather than intralesional steroid injections. We would like to report 9 year-old male with calcaneal simple bone cyst treated satisfactorily by minimally invasive endoscopic curettage and autologous bone grafting with review of the relevant literature.

Ampulla of Vater (AOV) cancer is rare malignant tumor which arises within the vicinity of the AOV. Metastatic AOV adenocarcinoma has poor prognosis, with an overall survival rate at 2 years ranging from 5 to 10%. The Surveillance, Epidemiology and End Results Program of the National Cancer Institute indicated that lymph node metastasis was present in as many as half of patients which were associated with poor prognosis and liver was the second most common site of distant metastasis in AOV cancer. In this case report, we describe a case of complete resolution of AOV cancer, which was already spread to retroperitoneal lymph node and liver. The patient underwent gemcitabine plus cisplatin chemotherapy for palliative aim. After 12 month of chemotherapy, image study showed partial remission, so intraoperative radiofrequency ablation therapy and pylorus preserving pancreaticoduodenectomy was done. AOV cancer was completely resected and the patient was followed up without recurrence for 7 months.

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.

Hemangioma in the esophagus is an uncommon tumor. There have only been about 30 cases reported in the world literatures. It occurs predominantly in men and although majority are asymptomatic, may cause bleeding and dysphagia. Hemangioma in the esophagus was diagnosed with a barium swallowed esophagography and endoscopy. The main treatment modes recommended are surgery and endoscopic resection. We experienced one case of cav ernous hemangioma occurring at the distal esophagus. The patient was a forty-six year old male with dysphagia and indigestion. Barium esophagogram showed a filling defect at the distal portion. Esophagoscopy showed a bluish polypoid mass. Surgical resection was per formed and the pathologic diagnosis was confirmed as cavernous hemangioma. Postoperative course was uneventful and the patient had been followed up without any problems.

An 81-year-old man underwent bronchoscopy to investigate the cause of his dyspnea symptoms. A benign natured mass was observed in the bronchus and was excised. The pathology examination revealed a fibroepithelial polyp. He has been asymptomatic since the simple bronchoscopic excision. A fibroepithelial polyp is a benign tumor with a mesodermal origin. It is commonly found in the skin, urogenital area and chest, but is extremely rare in the respiratory system. We report a case of a fibroepithelial polyp in the bronchus, which was treated with a bronchoscopic excision, with a brief review of the relevant literature.

Purpose: Various new techniques in thyroid surgery have been developed to improve visualization and reduce risk of complications. New approaches for robotic endoscopic thyroidectomy help to prevent neck scarring and improve surgical ergonomics. The purpose of this study was to compare the efficacy and adventages of an axillo-breast approach (AB group) and an only-axillary approach (OA group) in robotic endoscopic thyroidectomy. Methods: Between November 2008 and July 2014, axillo-breast approach was performed in 128 patients and only-axillary approach was performed in 128 patients for robotic endoscopic thyroidectomy. We compared tumor characteristics, surgical outcomes, and postoperative complications between the two approaches. The homogeneity between two groups of general characteristics was analyzed by independent t-test, fisher's exact test, Chi-square test. Results: There were no differences in terms of tumor characteristics, extent of thyroidectomy, retrieved nodes, and postoperative complications between the two approaches. The patients in OA group can avoid breast scar. Conclusion: Our techniques of AB and OA approaches for robotic endoscopic thyroidectomy are safe, feasible, and cosmetically excellent procedures. Also the OA approach for robotic endoscopic thyroidectomy is an attractive surgical option for patients with thyroid tumor who want an avoid breast scar.
