BACKGROUND: Computed tomography (CT) has become the predominant test for diagnosing acute appendicitis in adults. In children and young adults, exposure to CT radiation is of particular concern. We evaluated the rate of negative (unnecessary) appendectomy after low-dose versus standard-dose abdominal CT in young adults with suspected appendicitis. METHODS: In this single-institution, single-blind, noninferiority trial, we randomly assigned 891 patients with suspected appendicitis to either low-d

Loss of the tumor suppressor gene AT-rich interactive domain-containing protein 1A (ARID1A) has been demonstrated in several cancers, but its prognostic role is unknown. We aimed to investigate the risk associated with loss of ARID1A (ARID1A-) for all-cause mortality, cancer-specific mortality and recurrence of disease in subjects with cancer. PubMed and SCOPUS search from database inception until 01/31/2015 without language restriction was conducted, contacting authors for unpublished data. Eli

There is ongoing debate regarding the significance of complete or near-complete response after neoadjuvant chemoradiotherapy (CRT) for rectal cancer. This study assessed the prognostic value of the Dworak tumor regression grade (TRG) following neoadjuvant CRT and surgery primarily in patients with pathological stage (ypStage) II and III rectal cancer. The records of 331 patients who underwent neoadjuvant CRT followed by total mesorectal excision between 2004 and 2015 were retrospectively reviewe

PURPOSE: The aim of study was to determine the clinical characteristics and mutational profiles of the mismatch repair genes in hereditary nonpolyposis colorectal cancer (HNPCC) patients with small bowel cancer (SBC). EXPERIMENTAL DESIGN: A questionnaire was mailed to 55 members of the International Society for Gastrointestinal Hereditary Tumours, requesting information regarding patients with HNPCC-associated SBC and germ line mismatch repair gene mutations. RESULTS: The study population consis

A preoperative CGA indicating "high-risk" was associated with major postoperative complications in elderly patients who underwent surgery for colorectal cancer. Thus, using the CGA to identify elderly colorectal-cancer patients who should be given more care during postoperative management may be clinically beneficial.

This study was performed to determine the incidence, risk factors, and prognostic implications of venous thromboembolism (VTE) in Asian patients with colorectal cancer (CRC). Differences in clinical characteristics and prognostic impact between extremity venous thrombosis (or deep-vein thrombosis; DVT)/pulmonary embolism (PE) and intra-abdominal venous thrombosis (IVT) were also evaluated. For this study, consecutive CRC patients (N = 2,006) were enrolled and analyses were conducted retrospectiv

Familial adenomatous polyposis (FAP) is a clinically well-defined hereditary disease caused by germline mutations in the adenomatous polyposis coli (APC) gene. FAP is characterized by polyposis in the large bowel and variable extracolonic manifestations. With an increase of reported APC germline mutations, many reports have investigated genotype-phenotype correlations in FAP patients. Here, we analyzed the APC gene for germline mutations in 83 unrelated Korean FAP patients and investigated genot

The results of this study suggest that LA may lead to a shorter length of hospital stay and may have a lower risk of superficial incisional SSI than OA.

BACKGROUND: Three-dimensional (3D) imaging for laparoscopy was introduced to overcome the limitations of conventional two-dimensional (2D) imaging that lacked depth perception and spatial orientation. This study aimed to evaluate the effect of 3D imaging in laparoscopic colectomy with D3 lymphadenectomy for colon cancer. METHODS: From February 2014 to October 2016, the prospective database of 278 consecutive patients with colon cancer was analyzed retrospectively; these patients underwent laparo

The big-cohort database using the ICD 10th code for CRC appears to be accurate.
