Background /Aims: Endoscopic submucosal dissection (ESD) is currently considered the first-line treatment for the eradication of superficial neoplasms of the esophagus in Eastern countries. However, in the West, particularly in Latin America, the experience with esophageal ESD is still limited because of the high technical complexity required for its execution. This study aimed to present the results of the clinical application of ESD to manage superficial esophageal neoplasms in a Latin American center in over 100 consecutive cases.
Methods This retrospective study included consecutive patients who underwent endoscopic ESD for superficial esophageal neoplasms between 2009 and 2022. The following clinical outcomes were assessed: en bloc, complete, and curative resection rates, local recurrence, adverse events, and procedure-related mortality.
Results Esophageal ESD was performed mainly for squamous cell carcinoma (66.6%), high-grade intraepithelial neoplasia (17.1%), and adenocarcinoma (11.4%). En bloc and complete resection rates were 96.2% and 81.0%, respectively. The curative resection rate was 64.8%. Adverse events occurred in six cases (5.7%). Endoscopic follow-up was performed for an average period of 29.7 months.
Conclusions ESD performed by trained operators is feasible, safe, and clinically effective for managing superficial neoplastic lesions of the esophagus in Latin America.
Endoscopic submucosal dissection is recommended as an alternative therapy for early esophageal cancer. However, achieving curative resection in this procedure remains controversial since precise prediction of lymph node metastasis can be difficult. Here, we present the preliminary results of endoscopic submucosal dissection followed by concurrent chemoradiotherapy for early esophageal cancer with a high risk of lymph node metastasis. From May 2006 to January 2014, six patients underwent concurrent chemoradiotherapy after endoscopic submucosal dissection with a median follow-up period of 63 months. No complications were encountered during concurrent chemoradiotherapy. Although local recurrence did not occur in all patients, two patients were diagnosed with metachronous cancer. Overall, the survival rate was 100%. Thus, endoscopic submucosal dissection followed by concurrent chemoradiotherapy may be a feasible treatment for early esophageal cancer in patients with a high risk of lymph node metastasis. Future prospective large-scale studies are warranted to confirm our results.

A 62-year-old man with a flat early esophageal cancer was referred for endoscopic treatment. White light imaging revealed a pale red lesion, whereas linked color imaging (LCI) and blue laser imaging (BLI) yielded purple and brown images, respectively. Iodine staining demonstrated a large unstained area with a homogenous but very weak pink-color sign. This area appeared more clearly as purple and green on LCI and BLI, respectively; however, a different colored portion was observed at the 4 o’clock position inside the iodineunstained area. Histopathology findings of the resected specimen revealed squamous intraepithelial neoplasia at the 4 o’clock position and an esophageal squamous cell carcinoma in the remaining iodine-unstained area. LCI and BLI combined with iodine staining produce characteristic images that overcomes the pink-color sign, reflecting the histological features of a flat esophageal neoplasm. This new method is useful for detailed evaluation of early flat squamous cell neoplasms.

Although the surgical treatment of early esophageal cancer is a well-known curative modality, less invasive endoscopic methods have attracted significant attention recently on account of the fewer postoperative complications, better quality of life and preservation of the integrity of the esophagus. Among the various endoscopic techniques employed, photodynamic therapy (PDT) has been used to allow the selective destruction of malignant tissue through a photochemical effect after the administration of a photosensitizer for curative and palliative treatment purposes. This report describes a case of a 73-year-old man with early esophageal cancer, which had been diagnosed by fluorodeoxyglucose-positron emission tomography (FDG-PET) and endoscopy and a long history of chronic pulmonary diseases such as emphysema and radiation fibrosis. The patient was cured successfully with photodynamic therapy using porfimer sodium as the photosensitizer. (Korean J Gastrointest Endosc 2006;33: 3741)
Although esophageal cancer has been recognized as difficult to treat, its long-term survival statistics are significant lower than those of other gastrointestinal cancers, Postoperative 5-year survival of the early esophageal cancer which invasion is limited to the mucosa is close to 100%. So, early detection of esophageal cancer has been extremely significant. Progress in the endoscopic technique has enabled to make not only early detection but also curative endoscopic resection of the early esophageal cancers. The indication for curative endoscopic resection of esophageal cancer are as follows: mucosal cancer apart from gross invasion to the muscularis mucosae without nodal involvement and less than 2 cm * 2 cm in size of lesion. EEMR tube(endoscopic esophageal mucoaal resection tube), which was designed by Makuuchi in 1991, is widely used for resection of early esophageal cancers. We report a case of patient with early esophageal cancer, who was admitted due to complation of postprandial epigastric pain, diageosed by endoscopy, endoscopic ultra sonography and chest computerized tomography, and successfully resected by using EEMR tube.

Metachronous double cancer of primary early esophageal squamous cell carcinoma and invasive thymoma is a very rare condition. The invasive thymoma had been detected during the myathenia gravis evaluation and treated by radiation therapy 5 years ago. The esophageal lesion had a nodular-surfaced flat elevation at the mid-esophagus that was found by esophagoscopy. Radical resection for the lesions was undertaken after histologic confirmation. Postoperative pathologic examination documented that the esophageal squamous cell carcinoma was in the "early" stage involving the mucosal and submucosal layer only. We report a case of early esophageal cancer associated with invasive thyrnoma with literatures review.
