Although periodontal disease and gastrointestinal tract health are closely associated, few studies have investigated whether periodontitis is a risk factor for colorectal adenoma. The aim of this study was to investigate whether there is an association between periodontitis and the risk of colorectal adenoma in asymptomatic healthy people.From January 2013 to October 2015, we retrospectively enrolled 42,871 patients who underwent health screening at Kangbuk Samsung Hospital in South Korea. Demographic and clinical data were collected before colonoscopy. We calculated the odds ratio (OR) for adenoma in these patients.The median age was 39.3 ± 8.7 years and 70.4% of the patients were men; 32.5% had a body mass index (BMI) 25.0 kg/m2. The frequency of adenoma was 12% (n = 5136). A higher risk of adenoma was associated with the following factors: BMI 25.0 kg/m2 (OR 1.51, 95% confidence interval [CI]: 1.42–1.61), current smoker (OR 1.51, 95% CI: 1.42–1.61), former smoker (OR 1.28, 95% CI: 1.19–1.37), periodontitis (OR 1.95, 95% CI: 1.82–2.0), moderate alcohol intake (OR 1.8, 95% CI: 1.69–1.93), and heavy alcohol intake (OR 2.67, 95% CI: 2.24–3.18).Being male or a former or current smoker, alcohol intake above the moderate level, and periodontitis increase the risk of colorectal adenoma. These findings suggest that controlling oral disease is important to the prevention and management of colorectal adenoma. The findings of this study could be applied to risk stratification and colorectal cancer prevention programs, including screening guidelines.
PurposeThis study compared a subtotal colectomy to self-expandable metallic stent (SEMS) insertion as a bridge to surgery for patients with left colon-cancer obstruction.MethodsNinety-four consecutive patients with left colon-cancer obstruction underwent an emergency subtotal colectomy or elective SEMS insertion between January 2007 and August 2014. Using prospectively collected data, we performed a retrospective comparative analysis on an intention-to-treat basis.ResultsA subtotal colectomy and SEMS insertion were attempted in 24 and 70 patients, respectively. SEMS insertion technically failed in 5 patients (7.1%). The mean age and rate of obstruction in the descending colon were higher in the subtotal colectomy group than the SEMS group. Sex, underlying disease, American Society of Anesthesiologists physical status, and pathological stage showed no statistical difference. Laparoscopic surgery was performed more frequently in patients in the SEMS group (62 of 70, 88.6%) than in patients in the subtotal colectomy group (4 of 24, 16.7%). The overall rate of postoperative morbidity was higher in the SEMS group. No Clavien-Dindo grade III or IV complications occurred in the subtotal colectomy group, but 2 patients (2.9%) died from septic complications in the SEMS group. One patient (4.2%) in the subtotal colectomy group had synchronous cancer. The total hospital stay was shorter in the subtotal colectomy group. The median number of bowel movements in the subtotal colectomy group was twice per day at postoperative 3–6 months.ConclusionA subtotal colectomy for patients with obstructive left-colon cancer is a clinically and oncologically safer, 1-stage, surgical strategy compared to SEMS insertion as a bridge to surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
