POEM Technique (Continued)

The focus is on endoscopic submucosal dissection (ESD) and its role in cancer treatment. The impact of comorbidities on patient risk assessment is explored, as well as the comparison between endoscopy and surgery. Deep submucosal invasion is identified as a risk factor for lymph node metastasis. The factors influencing the choice of surgery after non-curative resection, such as age and comorbidities, are discussed. The need for an individualized approach in treating elderly patients is underscored.
