Aim: Sessile serrated lesions (SSL) have the potential for malignant transformation into colorectal carcinoma (CRC), which develops via pathway of carcinogenesis. Material and Methods: Based on colonoscopy pathology reports, all sessile or polyps in risk screening group were studied at an urban medical research center between July 2018 2022. We prospectively included consecutive classified as a...

BACKGROUND AND AIMS Lynch syndrome (also known as hereditary nonpolyposis colon cancer) is associated with an increased risk for colorectal cancer, which can arise despite frequent colonoscopic exams. We evaluated the adenoma miss rate of conventional colonoscopy in patients with Lynch syndrome, and compared the sensitivity of chromoendoscopy versus intensive inspection for detecting polyps mis...

BACKGROUND Gastric polyps, such as adenomas and hyperplastic polyps, can be found in various colonic polyposis syndromes. Unlike in sporadic gastric adenomas, in which the increased risk of colorectal neoplasia has been well characterized, information in sporadic gastric hyperplastic polyps was limited. AIM To evaluate the association of sporadic gastric hyperplastic polyps with synchronous c...

BACKGROUND Colorectal cancer is a major cause of morbidity and mortality and can arise through the adenoma-carcinoma sequence. Colonoscopy is considered the method of choice for population-wide cancer screening. AIM To assess the characteristics of endoscopically resected polyps in a consecutive series of patients who underwent colonoscopy at a university hospital and compare histopathology f...

Detecting and removing colonic polyps reduces the incidence of colorectal cancer [1]. Small polyps can be retrieved through a working channel into a suction trap or discarded, as almost all are indolent and pathological examination is not considered to be important [2,3]. As large polyps (≥10mm) may harbor invasive cancer, they should always be retrieved and sent for careful pathological examin...

BACKGROUND/AIMS Colonoscopic polypectomy is the best diagnostic and therapeutic tool to detect and prevent colorectal neoplasms. However, previous studies have reported that 17% to 28% of colorectal polyps are missed during colonoscopy. We investigated the miss rate of neoplastic polyps and the factors associated with missed polyps from quality-adjusted consecutive colonoscopies. METHODS We r...

AIM We designed this study to investigate the neutrophil lymphocyte ratio as a biomarker in distinguishing colonic polyps which are neoplastic or non-neoplastic. MATERIALS AND METHODS One hundred and twenty-five patients with colonic polyps were enrolled into the study. The following data were obtained from a computerized patient registry database: mean platelet volume (MPV), uric acid (UA), ...

Until recently, colonic polyps were traditionally classified as either hyperplastic or adenomatous, and only the latter were believed to have the potential to progress to carcinoma. However, it is now appreciated that a subset of serrated polyps also appear to have malignant potential. Serrated polyps are a heterogeneous group of colon polyps that include hyperplastic polyps, sessile serrated a...

Aim Polyp is called formations protruding into the lumen in the gastrointestinal tract. In this study, we aimed to determine frequency, anatomic distribution within the large bowel and pathologic types of colon polyps based on the colonoscopy results. Materials and methods The colonoscopy reports between 2010 and 2011 were analyzed retrospectively. Complaint of the patients on admission, the ...
