Highly Fluorescent Macrophages in Colonic Mucosa Under Autofluorescence Imaging Endoscopy: A Brief Case Report

Abstract A 62-year-old man presented to our department with repeated vomiting, abdominal pain, bloating, and constipation. Echocardiography and computed tomography revealed his thickened pericardium with multiple eggshell-like calcifications, and incomplete intestinal obstruction. Colonoscopy showed extensive focal erosions in the colonic mucosa. After fecal microbiota transplantation, the patient's nutritional status was improved, intestinal obstruction was relieved, and his cardiac function his was restored. This case may provide a new option for the treatment of refractory incomplete intestinal obstruction.

Risk Of Malignancy

Long-term exposure of colonic mucosa to urinary content and its association with increased risk of infection, mechanical and biochemical irritation, and malignancy have been described in the literature. Existing case reports and studies depict the low but distinct risk of malignancy in gastrointestinal segments which come in contact with urinary content as a result of surgical correction of urinary tract abnormalities. However, these reports are largely limited to colonic adenocarcinoma and urothelial cell carcinoma. Late urointestinal carcinoma in patients with ileal incorporation into the urinary tract has also been reported. To the best of our knowledge, however, there is only one case report documenting neuroendocrine (NE) cell hyperplasia in colonic mucosa after long-term cystoplasty. Our case is the first to describe microcarcinoids and diffuse NE hyperplasia occurring in a patient with congenital anorectal anomalies, resulting in long-term exposure of colonic mucosa to fecal stream and urinary content. This case, in conjunction with the reported cases in the literature, raises the distinct possibility of an association between exposure of colonic mucosa to urine and long-term development of malignancy, including NE neoplasms.

Inflammatory Bowel

Background. Crohn’s disease and ulcerative colitis are inflammatory bowel diseases (IBD) associated with colorectal cancer risk in long-standing diseases. In order to assess the colonic mucosa and to discover dysplastic or neoplastic lesions, advanced endoscopic techniques are needed. Such techniques are detailed in this review: chromoendoscopy, autofluorescence imaging (AFI), narrow band imaging (NBI), i-SCAN, Fujinon Intelligent Color Enhancement (FICE) and confocal laser endomicroscopy (CLE). Aim. The aim of the review is to describe and establish the clinical impact of advanced endoscopic techniques, that could be used in IBD patients’examination in order to assess mucosal healing, microscopic inflammation, dysplasia or neoplasia. Materials and Methods. A literature research about new endoscopic approaches of patients with IBD was made. Results. A lot of studies have been performed to reveal which imaging technique might be used for IBD surveillance. Regarding dysplasia or neoplasia detection and mucosal healing or inflammation assessment, CE proved to be superior to white light endoscopy (WLE), while NBI and AFI did not show an encouraging result. I-SCAN did not improve the colonoscopy quality while FICE has been used in a few studies. CLE could be used to characterize a lesion, providing the same results as conventional histology. Conclusion. At the moment, CE is the only technique which has been included in guidelines for IBD surveillance. CLE can be used to assess any lesion detected with WLE during surveillance, while the other imaging techniques require more studies to determine their efficacy or inefficacy.
