RATIONALE A solitary Peutz-Jeghers-type polyp is a hamartomatous polyp which without either mucocutaneous pigmentation or a family history of Peutz-Jeghers syndrome (PJS). It can occur in all of the gastrointestinal tract, but it is extremely rare in the stomach. PATIENT CONCERNS A 53-year-old man was admitted to the local hospital with left upper abdominal pain lasting 2 weeks. A gastroscopy...

A 71-year-old female with hypertension presented painless rectal bleeding and found to have a soft mass on exam. The colonoscopy revealed large pedunculated polyp patchy discoloration arising from the dentate line (Fig. 1). Biopsies of were obtained.

BACKGROUND/STUDY AIM  Linked color imaging (LCI) by a laser endoscope (Fujifilm Co, Tokyo, Japan) is a novel narrow band light observation. In this study, we aimed to investigate whether LCI could improve the visibility of colorectal polyps using endoscopic videos. PATIENTS AND METHODS  We prospectively recorded videos of consecutive polyps 2 - 20 mm in size diagnosed as neoplastic polyps. Th...

A 70-year-old woman visited our hospital complaining of anemia. Laboratory testing revealed a peripheral blood hemoglobin concentration of 9.4g/dL. Upper and lower gastrointestinal endoscopic examinations were performed to investigate the cause of the anemia. The findings of the upper endoscopic examination were normal. However, the lower endoscopic examination revealed a semipedunculated polyp...

Adult intussusception is clinically rare. We report a case with colon intussusception caused by a pedunculated polyp of the sigmoid colon in a 54-year-old male. Abdominal ultrasonographic screening for hematochezia showed intussusception in the sigmoid colon, demonstrating a multiple concentric ring sign and a mobile leading colon polyp. Histological examination of a biopsy specimen of the poly...

Abstract Aims The Joint Advisory Group on GI Endoscopy (JAG) has set key quality indicators for colonoscopy, which includes an adenoma detection rate of a minimum 15%. Given the difficulty in reporting rate, JAG have stated that polyp is accepted as surrogate measure. Our aim was to assess whether can be used substitute marker detection, by examining histology samples taken polyps determine wha...
