There are many reasons why doctors would not to be able to communicate with patients. First, medicine is science or humanity? Although object of medicine is human, modern medicine tends to regard human as broken machine. Second, gastroenterologists are overloaded by treatment of patients, providing education, attending academic conference, and writing papers. Above all things, it is much worse for gastroenterologists because of endoscopic procedures. The other problem is attitude of modern society about human suffering. Sufferings come from not only body but also mind or spirit. Although there are may difficult problems, if doctors listen to patients' history by their side, it will help to restore their faith. In addition, we need humanity education and improvement plans for medical service system.

Colorectal cancer remains a significant health burden in South Korea, being the third most diagnosed cancer in the country. Despite advances in treatment, patients with metastatic colorectal cancer still face limited survival rates, with resection often deemed impossible for the majority. This review discusses the current state of chemotherapy in colorectal cancer treatment, focusing on both adjuvant chemotherapy post-surgery and palliative chemotherapy for metastatic cases. The article highlights recent updates in treatment guidelines, including the use of immunotherapy and the role of circulating tumor DNA (ctDNA) in personalized medicine. The integration of these novel approaches aims to enhance treatment efficacy, improve patient survival, and reduce recurrence rates, paving the way for more tailored and effective therapeutic strategies in colorectal cancer management.

Endoscopic mucosal resection (EMR) is an endoscopic alternative to surgical resection of mucosal and submucosal neoplastic lesions. Prior to the development of knives, EMR could be performed with accessories to elevate the lesion. After the development of various knives, en bloc resection was possible without other accessories. So, recently, simple snaring without suction or endoscopic submucosal dissection using knife in the epithelial lesions such as adenoma or early mucosal cancer has been performed. However, for easy and complete resection of subepithelial lesions such as carcinoid tumor, a few accessories are needed. Complete resection of rectal carcinoid tumors is difficult to achieve with conventional endoscopic resection techniques because these tumors often extend into the submucosa. The rate of positive resection margin for tumor is lower in the group of EMR using a cap (EMR-C) or EMR with a ligation device (EMR-L) than conventional EMR group. EMR-C and EMR-L (or endoscopic submucosal resection with a ligation device) may be a superior method to conventional EMR for removing small rectal carcinoid tumors.
