Recently, some studies have shown that diabetes mellitus and metabolic syndrome increase the risk of colorectal neoplasms. Although the mechanism is not known, those have been proposed to contribute to this phenomenon, including insulin resistance, oxidative stress, and adipokine production. The objective of this study was to assess the association between(More)
Although small rectal carcinoid tumors can be treated using local excision, complete resection can be difficult because tumors are located in the submucosal layer. We evaluate the factors associated with pathologically complete local resection of rectal carcinoid tumors. Data were analyzed of 161 patients with 166 rectal carcinoid tumors who underwent local(More)
GOALS This large prospective study attempted to analyze the effect of various prior surgery on colonoscopy performance. BACKGROUND It is generally presumed that colonoscopy in patients with a history of abdominal or pelvic surgery is difficult. This difficulty is apparently due to adhesions and anatomic alterations after surgery but the incidence, site,(More)
The outcomes of colorectal cancer are determined by host factors, including systemic inflammation. The purpose of this study was to evaluate the prognostic significance of fibrinogen and inflammation-based scores, as markers of the inflammatory response, in colon cancer. We retrospectively reviewed the medical records of patients with nonmetastatic colon(More)
Three-drug combination of fluoropyrimidine, irinotecan and oxaliplatin has shown survival benefits in patients with metastatic colorectal cancer (mCRC). Recently we performed a phase II study of a new 3-drug regimen, TIROX (S-1 plus irinotecan and oxaliplatin) to evaluate efficacy and safety in refractory mCRC patients. Patients with refractory to all of 3(More)
BACKGROUND & AIMS Small studies have shown inconsistent results regarding the association between abdominal visceral adipose tissue and colorectal adenomas. We evaluated the effects of visceral adipose tissue volume on the development and growth of colorectal adenomas. METHODS A total of 3922 participants underwent colonoscopy and computed tomography from(More)
BACKGROUND Reduced-volume bowel preparation with a low-residue diet prior to colonoscopy would result in better patient compliance and sufficient bowel preparation. OBJECTIVE To compare the clinical efficacy of reduced-volume sodium picosulfate and a prepackaged low-residue diet with that of the standard bowel preparation using 4 L of PEG solution. (More)
The predictive role of mismatch repair (MMR) status for survival after sporadic colorectal cancer remains a point of controversy. This study was designed to test the prognostic value of MMR status in sporadic colorectal cancers. The study included 318 patients with sporadic colorectal cancer who underwent primary tumor resection. MMR status was determined(More)
OBJECTIVE We aimed to investigate the association between a family history (FH) of colorectal cancer (CRC) and cancer recurrence and survival in patients with stage III CRC. METHODS From April 2001 to December 2007, 1102 patients with stage III CRC were enrolled and their data including FH, clinicopathological characteristics of the tumor were(More)
PURPOSE The purpose of this study was to extend the application of self-expandable metallic stents by investigating their usefulness in treating colorectal obstructions caused by unresectable extrinsic tumors. METHODS From January 2000 to November 2005, a total of 60 colorectal stenting procedures were performed, and 57 stents were deployed in 39 patients(More)
