Association of Metabolic Syndrome Components and Colonic Diverticulosis in the Very Elderly: A Tertiary Health Network Study.

Introduction There is scarce data about the association of metabolic syndrome (MetS) or its components with the development of colonic diverticulosis (CD) in the elderly. We aim to determine the association of MetS and its components with CD in the elderly aged ≥75 years. Methods We conducted a retrospective chart review at St. Luke's University Health Network to identify patients who underwent a colonoscopy between 2011 and 2020. We collected data on patient demographics, comorbidities, and colonoscopy findings. Statistical analyses were conducted to compute means and frequencies of patient characteristics and rates of CD, as well as to test for associations between potential risk factors and the presence of CD.  Results A total of 1239 patients were included with a median age of 80 years, 57.6% females, 89.5% Caucasians, 72.9% with CD, and 66.7% having a left-sided disease. On bivariate analysis, the older age group (p=0.02), Caucasian ethnicity (p=0.01), and hypertension (p=0.04) were found to be significant risk factors for developing CD. Multivariate regression analysis showed older age group and hypertension (OR=1.47, 95% CI: 1.66-2.02, p=0.02) were major risk factors. A significant proportion of patients with left-sided disease had Caucasian ethnicity (p<0.001), while female gender, obesity, and iron deficiency anemia were also seen more frequently, although without statistical significance.  Conclusion In the elderly (>75 years old), our study found hypertension to be associated with an increased risk of CD, while impaired fasting glucose (IFG) was protective. Most patients exhibited isolated left-sided diverticulosis, with pan-diverticulosis associated with higher proportions of adverse health indicators, including American Society of Anesthesiologists (ASA) score ≥3, IFG, hypertriglyceridemia, hypertension, and hypothyroidism. Further research with larger sample sizes in similar age groups is needed to expand upon these findings.

Plummer-Vinson Syndrome: A Rare Cause of Dysphagia in an Octogenarian.

BACKGROUND Plummer-Vinson syndrome is a rare disease that presents with iron-deficiency anemia, dysphagia, and esophageal webs. It usually occurs in middle-aged White women, and it increases the risk for esophageal cancer. The prevalence of Plummer-Vinson syndrome has decreased due to early detection of iron deficiency and repletion of iron stores. Although Plummer-Vinson syndrome has also been commonly described in children and adolescents, it is seldom reported in the elderly population. CASE REPORT An 88-year-old women with a history of mild cognitive impairment, allergic rhinitis, and gastroesophageal reflux disease presented with difficulty in swallowing solid foods. She had a decreased appetite, along with a 4.5-kg weight loss in the last 1 year. She was also found to have severe iron deficiency and mild anemia. Her dysphagia continued to progress even after starting iron supplementation for her iron deficiency. She eventually had a food bolus trapped in her cervical esophagus that required removal via esophagogastroduodenoscopy. A barium swallow revealed a narrowing in the upper esophagus. A repeat esophagogastroduodenoscopy revealed an esophageal web that was dilated, resulting in relief of symptoms. CONCLUSIONS Dysphagia is reported in up to 10% of the elderly population. It commonly causes malnutrition and is associated with increased mortality. The usual etiologies include cognitive dysfunction, neurological disorders, and/or esophageal dysmotility or narrowing. Although the incidence of Plummer-Vinson syndrome has decreased over time, the possibility of its presence should not be overlooked. To our knowledge, the current case is the third case of dysphagia related to Plummer-Vinson syndrome reported in an octogenarian in the literature so far. Iron replacement can help resolve dysphagia in Plummer-Vinson syndrome but dilation of esophageal webs may sometimes be required.

Ischemic Colitis in a Patient on Venovenous Extracorporeal Membrane Oxygenation (VV-ECMO) Treatment: An Emerging Complication?

BACKGROUND There have been few reports of colonic ischemia in patients receiving venovenous extracorporeal membrane oxygenation (VV-ECMO) treatment, and all patients died during the same hospitalization. CASE REPORT A 48-year-old man was admitted with acute respiratory failure secondary to multifocal pneumonia and required VV-ECMO treatment. He developed abdominal distention and colon dilatation and was subsequently found to have ischemic colitis. He was able to recover from critical illness and ischemic colitis with supportive treatment including colonic decompression. CONCLUSIONS Ischemic colitis is associated with mortality in patients receiving ECMO treatment. The understanding of the pathophysiology is still evolving and requires further research to improve patient outcomes.

Colonic Ischemia After Vaginal Delivery.

Ischemic colitis is a common form of bowel ischemia typically associated with vasculopathy in advanced age. Although some predisposing factors can increase the risk of developing ischemic colitis, the disease is relatively uncommon in young adults. Furthermore, cases of ischemic colitis associated with pregnancy are exceedingly rare. We present a young woman with severe ischemic colitis after vaginal delivery that ultimately led to sigmoid resection due to persistent stricturing.

Repeat colonoscopy's value in gastrointestinal bleeding.

AIM: To assess the diagnostic yield and clinical value of early repeat colonoscopies for indications other than colorectal cancer (CRC) screening/surveillance. METHODS: A retrospective review of patients who had more than one colonoscopy performed for the same indication within a three year time frame at our tertiary care referral hospital between January 1, 2000 and January 1, 2010 was conducted. Exclusion criteria included repeat colonoscopies performed for CRC screening/surveillance, poor bowel preparation, suspected complications from the index procedure, and incomplete initial procedure. Primary outcome was new endoscopic finding that led to an endoscopic therapeutic intervention or any change in clinical management. Clinical parameters including age, sex, race, interval between procedures, indication of the procedure, presenting symptoms, severity of symptoms, hemodynamic instability, duration between onset of symptoms and when the procedure was performed, change in endoscopist, withdrawal time, location of colonic lesions and improvement of quality of bowel preparation were analyzed using bivariate analysis and logistic regression analysis to examine correlation with this primary outcome. RESULTS: Among 19  772 colonoscopies performed during the above mentioned period, 947 colonoscopies (4.79%) were repeat colonoscopies performed within 3 years from the index procedure. Out of these repeat colonoscopies, 139 patient pairs met the inclusion criteria. The majority of repeat colonoscopies were for lower gastrointestinal bleeding (88.4%), change in bowel habits (6.4%) and abdominal pain (5%). Among 139 eligible patient pairs of colonoscopies, only repeat colonoscopies that were done for lower gastrointestinal bleeding and abdominal pain produced endoscopic findings that led to a change in management [25 out of 123 (20.33%) and 2 out of 7 (28.57%), respectively]. When looking at only recurrent lower gastrointestinal bleeding cases, new endoscopic findings included 8 previously undetected hemorrhoid lesions (6.5%), 7 actively bleeding lesions requiring endoscopic intervention, which included 3 bleeding arterio-venous malformations (2.43%), 2 bleeding radiation colitis (1.6%), and 2 bleeding internal hemorrhoids (1.6%), 5 previously undetected tubular adenomas [4 were smaller than 1 cm (4.9%) and 1 was larger than 1 cm (0.8%)], 3 radiation colitis (2.43%), 1 rectal ulcer (0.8%), and 1 previously undetected right sided colon cancer (0.8%). Of the 25 new endoscopic findings, 18 (72%) were found when repeat colonoscopy was done within the first year after the index procedure. These findings were 1 rectal ulcer, 3 radiation colitis, 4 new hemorrhoid lesions, 3 previously undetected tubular adenomas, and 7 actively bleeding lesions requiring endoscopic intervention. Of all parameters analyzed, only the interval between procedures less than one year was associated with higher likelihood of finding a clinically significant change in repeat colonoscopy (odds ratios of interval between procedures of 1-2 year and 2-3 year compared to 0-1 year were 0.09; 95%CI 0.01-0.74, P = 0.025 and 0.26; 95%CI 0.09-0.72, P = 0.010 respectively). No complications were observed among all 139 colonoscopy pairs. CONCLUSION: There is clinical value of repeating a colonoscopy for recurrent lower gastrointestinal bleeding, especially within the first year after the index procedure.
