AbstractOptical diagnosis during colorectal cancer screening is instrumental in deciding whether or not to resect colorectal lesions, choose the appropriate technique and to properly communicate with the pathologist. The latter is even more important when it comes to serrated lesions with the latest WHO classification justifying a pathology diagnosis of a serrated lesion with a minimum criterion of characteristic findings in just one crypt, which may only be detectable when adequate sectioning and scrutinization is performed. Here, we present a unique case of comparatively small rectal lesions with typical endoscopic findings warranting a diagnosis of a serrated lesion (open pit pattern) and adenoma (valley sign).

Abstract: Introduction and aim: The aim was to assess the incidence of endoscopic findings based on the indication of the procedures in upper/lower endoscopies, and measuring quality indicators of colonoscopies at the 1st Department of Medicine, Semmelweis University, Budapest. Method: Data of 2987 patients (male/female:1361/1626, mean age: 60.7 years(y), SD: 16.7y) between 01.01.2010 and 31.12.2011 were analyzed. Both inpatient and outpatient records were collected. Results: Incidence of peptic ulcer disease, esophageal varices, gastric polyps and gastric cancer were 10.8%, 4.5%, 6.1%, 2.9% in upper endoscopies, respectively. In colonoscopies colorectal polyps, diverticulosis, colorectal cancer and IBD were found in 29.9%, 22.4%, 6.9%, 9.7%, respectively. In patients having upper endoscopy with GI bleeding indication, older age (p<0.001), male gender (p<0.001, OR: 1.64), acenocoumarol/heparin use (p<0,001, peptic ulcers and esophageal varices were more frequent (p<0.001, OR: 2.83 and p<0.001, OR: 2.79), while in colonoscopies colorectal cancer had higher incidence (p<0.001, OR:3.27). 81% of colonoscopies were complete. Causes of incomplete procedures were ineffective bowel preparation (38.2%), technical difficulties (25.1%) and strictures (20.5%). Conclusion: The endoscopic findings and quality indicators (adenoma detection rate, coecal intubation rate) were in line with that reported in published series. Orv.

Abstract Background: Colorectal cancer (CRC) mostly develops through the traditional “adenoma-carcinoma sequence”, however there is a rare “de novo” carcinogenic pathway in which cancer originates from normal mucosa. Here, we report a case of early CRC caused by “de novo” carcinogenesis with submucosal invasion and conduct a literature review of this special type of CRC.Case presentation: A 66-year-old man underwent a screening colonoscopy that revealed a polyp-like lesion (type 0-IIa+IIc in the Paris classification) approximately 0.5 cm in diameter in the descending colon. The patient underwent endoscopic submucosal dissection (ESD); postoperatively, he was pathologically diagnosed with moderately differentiated adenocarcinoma without an adenomatous component from the “de novo” carcinogenic pathway, accompanied by submucosal invasion to a depth of 600 μm. There was no venous or lymphatic permeation, and the margins were negative. A year later, follow-up examinations did not reveal tumour recurrence.Conclusions: Early “de novo” cancer has a low incidence and a low discovery rate through endoscopy. In this case report, we provide informative details about the presentation of such cancers under endoscopy and further support for the aggressive malignant potential of early “de novo” cancer. The development of advanced CRC can be effectively prevented, and the prognosis of these patients can be improved with active early treatment.
