One mid-esophageal carcinoma underwent esophagogastrectomy using an exclusive right thoracic approach entailing mobilization of the stomach through the esophageal hiatus. 62 year old male farmer was admitted with chief complaints of dysphagia and weight loss of 5 Kg. for 6 months, and regurgitation after soft meal for one week prior to this admission. Preoperative esophagogram revealed stricture with fungating mass at the level of the carina, which was diagnosed as squamous cell carcinoma at the time of esophagoscopic biopsy about 33 cm from incisor. Bronchoscopy revealed no invasive lesion or carinal fixation, and laboratory examinations were excellent for operative intervention. An exclusive right thoracic approach through right 5th rib bed was made for radical esophagectomy, mobilization of the stomach through the esophageal hiatus and primary esophagectomy. Postoperative recovery was uneventful except increased bronchial secretion due to senile emphysema, and follow up for 5 months after esophagectomy revealed good functioning esophagus with mild epigastric fullness after meal. Exclusive right thoracic approach for radical esophagectomy seems to be the procedure of choice in selected cases.

Esophageal squamous cell carcinoma (ESCC) is the most common histologic subtype of esophageal cancer and is characterized by a poor prognosis. Determining gene changes in ESCCs should improve understanding of putative risk factors and provide potential targets for therapy. We sequenced about 55 million pair-end reads from a pair of adjacent normal and ESCC samples to identify the gene expression level and gene fusion. Sanger sequencing was used to verify the result. About 17 thousand genes were expressed in the tissues, of which approximately 2400 demonstrated significant differences between tumor and adjacent non tumor tissue. GO and KEGG pathway analysis revealed that many of these genes were associated with cellular adherence and movement, simulation responses and immune responses. Notably we identified and validated one fusion gene, HLA-E and HLA-B, located 1 MB apart. We also identified thousands of remarkably expressed transcripts. In conclusion, a novel fusion gene HLA-E and HLA-B was identified in ESCC via whole transcriptome sequencing, which would be a biomarker for ESCC diagnosis and target for therapy, shedding new light for better understanding of ESCC tumorigenesis.

식도암 수술 시 종격동 림프절 절제는 식도암의 재발과 관련하여 환자의 장기 생존율을 높이는 하나의 방법이다. 하지만 좌측 종격동 림프절 절제는 수술 시야의 제한으로 인해 절제가 거의 불가능하다. 이에 본원에서는 식도암 최소 침습 수술 시 경부 절개창을 통하여 흉강경을 이용한 좌측 종격동 림프절 절제를 시행하였기에 보고하는 바이다.

내시경 초음파검사는 식도벽의 조직학적 층구조를 가장 유사하게 반영하는 검사법으로 식도 병변의 진단과 치료전략에 필수검사이다. 표재성 식도암에서 고주파 미세탐촉자를 이용한 EUS는 내시경 절제 같은 국소치료가 가능한 환자들을 선별하는 데 중요한 역할을 한다.

Superficial esophageal neoplasms (SENs) are being diagnosed increasingly frequently due to the screening endoscopy and advances in endoscopic techniques. Endoscopic resection (ER) is a relatively noninvasive treatment method with low morbidity and mortality that provides excellent oncologic outcomes. Endoscopic submucosal dissection is associated with higher rates of en bloc, complete and curative resections and lower rates of local recurrence than endoscopic mucosal resection. The most serious complication of ER is stricture, the treatment and prevention of which are crucial to maintain the patient's quality of life. ER for SEN is feasible, effective, and safe and can be considered a first-line treatment for SENs in which it is technically feasible.

Definitive chemoradiotherapy (CRT) with its significant efficacy and safety in esophageal cancer is reserved for patients with unresectable tumor or those who decline surgery. However, the incidence of locoregional failure or recurrence after definitive CRT remains high. Although esophagectomy is the standard treatment for locoregional failure or recurrence, this approach is associated with high mortality and morbidity. A 56-year-old man diagnosed with esophageal squamous cell carcinoma who refused to undergo surgery received definitive CRT. An endoscopy for response assessment performed after 2 months revealed a residual lesion, which was completely resected by salvage endoscopic submucosal dissection. To the best of our knowledge, endoscopic resection in locoregional failure or recurrence after definitive CRT is very rarely reported, and there are no guidelines or consensus to date. Here, we report a case of successful salvage endoscopic resection of residual lesion after definitive CRT.

Intramural leiomyoma is the most common benign esophageal tumor, but it is rare compared with carcinoma. Although the most common symptom is dysphagia, this tumor may not cause symptoms before attaining large size. Radiographic and endoscopic findings allow an accurate diagnosis to be made before operation in most patients. The treatment of choice is enucleation without mucosal encroachment. Recently, we experienced two cases of esophageal leiomyoma on the mid portion of esophagus and enucleation of tumors were done by blunt dissection with caution. In one case, postoperative chylothorax was complicated, but cured with conservative treatment. The tissue diagnosis was confirmed with pathological finding.

Carcinosarcoma of the esophagus have an interesting pathologic feature of admixture of carcinomatous and sarcomatous lesion and accounts for 0.5∼1.5% of all esophageal neoplasm. Generally, it has been reported that these have better prognosis than the squamous cell carcinoma. We have experienced two cases of carcinosarcoma occurring at the mid-esophagus. In both two cases, Ivor Lewis operation was performed and lymph node metastasis was absent. The pathologic diagnosis was confirmed as carcinosarcoma. Postoperative course was uneventful and the patients have been followed up for 3 months and 3 years, respectively, without any problems. We report these cases with a brief review of the literatures.

Acquired communicated diverticula between the esophagus and respiratory system are infrequent, and they are caused by carcinoma, trauma, infection, and traction. This report reviews the feature of benign esophagobronchial fistula due to midesophageal diverticulum. Patient is twenty year old man with excellent result by surgical intervention . The surgical procedures consist of divertuculectomy and superior segmentectomy of lower lobe of right lung. Clinically and radiologically, the patient is free from substernal distress, regurgitation, esophagorespiratory fistula, and esophageal stricture after surgical treatment.
