This is a prospective randomized trial that aimed to compare the short-term clinical outcomes and systemic inflammatory/cytokine responses of endoscopic submucosal dissection versus laparoscopic resection for early colorectal neoplasms that are not amenable to en bloc endoscopic resection with conventional techniques.
Colonoscopy plays an increasingly important role in the diagnosis and treatment of colorectal pathologies. The recent progress in endoscopic technologies and interest in colorectal cancer screening have enabled the diagnosis of a larger number of early colorectal neoplasms, including benign polyps and early cancers. Colonoscopic polypectomy remains the cornerstone of therapy for the majority of colorectal polyps and helps prevent colorectal cancer. However, if colorectal neoplasms are too large or cannot be removed "en bloc" endoscopically, operative procedures are required to reduce risks of incomplete removal and local recurrence. Laparoscopic resection represents a minimally invasive alternative for treating colorectal neoplasms that are not amenable to en bloc endoscopic resection. However, laparoscopic surgery has to be done under general anesthesia, is associated with operative morbidity, and is expensive.
Endoscopic submucosal dissection (ESD) is a revolutionary endoscopic procedure that enables en bloc resection of large gastrointestinal tumors, irrespective of the size of the lesion. ESD, which was pioneered in Japan for the treatment of early gastric neoplasms, has now been successfully applied to the colon and rectum. ESD has been shown by recent studies to be a safe and effective resection technique for large early colorectal neoplasms. However, no report can be found in the literature comparing ESD and laparoscopic resection for early colorectal neoplasms that are not amenable to en bloc endoscopic resection with conventional techniques. Furthermore, it remains unclear whether ESD is less invasive than laparoscopic surgery in terms of systemic inflammatory and cytokine responses, and all these may have implications for cancer recurrence.
We propose to conduct a prospective randomized trial to compare the short-term clinical outcomes and systemic inflammatory/cytokine responses of ESD versus laparoscopic resection for early colorectal neoplasms that are not amenable to en bloc endoscopic resection with conventional techniques. The overall costs of the two therapeutic approaches will also be compared. Findings of this proposed project may provide evidence-based clarification of the efficacy and safety of ESD in treating early colorectal neoplasms. We hypothesize that ESD is associated with lower morbidity, earlier recovery, shorter hospital stay, and lower costs when compared with laparoscopic resection. A faster recovery and earlier discharge after ESD may reduce financial burden to the hospital and health care system. The results of this proposed project may have a significant impact on the future treatment strategy for early colorectal neoplasms, and may provide new insights into the systemic inflammatory responses of ESD.

A method for removing lesions from gastrointestinal MUCOUS MEMBRANES. The mucosal tissue with the lesion is elevated by injecting a solution into the submucosal layer underneath it. The elevated tissue with the lesion is then cut out.
Tumors or cancer of the COLON or the RECTUM or both. Risk factors for colorectal cancer include chronic ULCERATIVE COLITIS; FAMILIAL POLYPOSIS COLI; exposure to ASBESTOS; and irradiation of the CERVIX UTERI.
A group of autosomal-dominant inherited diseases in which COLON CANCER arises in discrete adenomas. Unlike FAMILIAL POLYPOSIS COLI with hundreds of polyps, hereditary nonpolyposis colorectal neoplasms occur much later, in the fourth and fifth decades. HNPCC has been associated with germline mutations in mismatch repair (MMR) genes. It has been subdivided into Lynch syndrome I or site-specific colonic cancer, and LYNCH SYNDROME II which includes extracolonic cancer.
Dissection in the neck to remove all disease tissues including cervical LYMPH NODES and to leave an adequate margin of normal tissue. This type of surgery is usually used in tumors or cervical metastases in the head and neck. The prototype of neck dissection is the radical neck dissection described by Crile in 1906.
Hereditary nonpolyposis colorectal neoplasms associated with other malignancies, more commonly of ovarian or uterine origin. When also associated with SEBACEOUS GLAND NEOPLASMS, it is called MUIR-TORRE SYNDROME.
