BACKGROUND/AIM: Histopathological examination is crucial for the effective management of endometrial polyps. Immunohistochemical markers such as p16 and c-Kit may facilitate the differential diagnoses of benign and malignant polyps. The aim of the present study was to explore the expression levels of c-Kit (CD117) and p16 in endometrial polyps of postmenopausal women. MATERIALS AND METHODS: Twenty-five hysterectomy specimens with malignant endometrial polyps and hysterectomy or polypectomy specimens featuring 55 benign polyps were studied...

Colonoscopy, either performed as screening or as a therapeutic proceedure, is, in general, very safe with only a few cases of serious complications. Most cases of bleeding after endoscopic polypectomy can be safely managed endoscopically. The rare cases of colonic perforations still have to be managed by surgical intervention. The postpolypectomy-coagulation syndrome and a cecal volvulus are very rare complicatoions after colonoscopy. In the current manuscript, we describe a rare case of a cecal volvulus after routine colonoscopy due to an unknown mobile coecum as a predisposition...

Inverted Papilloma (IP) is an uncommon and locally aggressive benign tumour of sinonasal region, which tends to recur after surgical resection. Most tumours are confined to the lateral nasal wall and sinuses, with maxillary sinus being most commonly affected and a male preponderance. It has a known association with in situ and invasive carcinomas with a <10% rate of malignant transformation. Most common association has been seen with squamous cell carcinoma and extremely rare association with adenocarcinoma and small cell carcinoma...

Colorectal cancer screening has become a standard of care in industrialized nations for those 50 to 75 years of age, along with selected high-risk populations. While colorectal cancer screening has been shown to reduce both the incidence and mortality of colorectal cancer, it is a complex multi-disciplinary process with a number of important steps that require optimization before tangible improvements in outcomes are possible. For both opportunistic and programmatic colorectal cancer screening, poor participant uptake remains an ongoing concern...

An endometrial polyp is a frequently encountered abnormality of the uterine cavity that may interfere with normal embryo implantation. In this case-control study, we enrolled 56 women in whom endometrial polyps were incidentally diagnosed by transvaginal ultrasound and office hysteroscopy during IVF (Group 1), and 112 age-matched IVF controls randomly selected from the same time period (group 2). Cryopreserved embryos were transferred in group 1 whereas fresh embryos were transferred in group 2, which is a limitation of the study...

BACKGROUND AND OBJECTIVES: Gastrointestinal cancers are the most frequently occurring cancers worldwide. Diagnosis and removal of polyps during screening endoscopy decreases the prevalence of colon cancer and cancer-related mortality, and it is considered to be the gold standard in gastrointestinal system cancer prevention. Technological innovations in endoscopy have led to revolutionary developments in many areas. Flexible spectral imaging color enhancement (FICE) and narrow-band imaging (NBI) are forms of digital chromoendoscopy and enhance the endoscopic images without the need for a dye...

BACKGROUND: Diminutive (1-5 mm) and small (6-9 mm) polyps comprise 90% of detected lesions during colonoscopy and rarely contain advanced histology or colorectal cancer (CRC). Routine removal of these lesions results in a significant burden to colonoscopy programs. At the same time, the risk for progression of these polyps to CRC is unclear. We performed a systematic review to explore the natural history of diminutive and small colorectal polyps. METHODS: We searched MEDLINE and EMBASE for studies investigating the natural history of colorectal polyps...

AIM: To identify risk factors for post-polypectomy bleeding (PPB), focusing on antithrombotic agents. METHODS: This was a case-control study based on medical records at a single center. PPB was defined as bleeding that occurred 6 h to 10 d after colonoscopic polypectomy and required endoscopic hemostasis. As risk factors for PPB, patient-related factors including anticoagulants, antiplatelets and heparin bridge therapy as well as polyp- and procedure-related factors were evaluated...

We have developed a technique to study how good computers can be at diagnosing gastrointestinal lesions from regular (white light and narrow banded) colonoscopic videos compared to two levels of clinical knowledge (expert and beginner). Our technique includes a novel tissue classification approach which may save clinician's time by avoiding chromoendoscopy, a time-consuming staining procedure using indigo carmine. Our technique also discriminates the severity of individual lesions in patients with many polyps, so that the gastroenterologist can directly focus on those requiring polypectomy...

Uterine polyps can cause abnormal bleeding in women. Conventional practise is to remove them under general anaesthesia but advances in technology have made it possible to perform polypectomy in the office setting. We conducted a patient-preference study to explore women's preferences for treatment setting and to evaluate the effectiveness and treatment experience of women undergoing uterine polypectomy. Three hundred ninety-nine women with abnormal uterine bleeding who were found to have uterine polyps at diagnostic hysteroscopy were recruited...

Background. Barrett's esophagus is associated with an increased risk of adenocarcinoma. Dysplasia in Barrett's esophagus is a precursor to adenocarcinoma. Rarely, dysplastic polypoid lesions are superimposed on Barrett's esophagus. Most reported cases of polypoid dysplasia in Barrett's esophagus have been advanced on presentation and treated with esophagectomy. We describe two cases of polypoid changes in Barrett's esophagus and treatment with polypectomy followed by radiofrequency ablation. Cases. A 75 yo male presented with esophageal polyps, which on biopsy showed gastric cardia/foveolar mucosa with focal intestinal metaplasia without dysplasia...

BACKGROUND: Endoscopic polypectomy is widely used for colorectal polyps. However, for giant pedunculated colorectal polyps (≥3 cm), conventional techniques are so difficult with en bloc resection that patients had to be transferred to surgery. We had firstly reported our first experience with an insulated-tip knife to successfully remove a giant pedunculated polyp in the sigmoid colon. In this study, our aim was to explore safety and feasible of insulated-tip knife endoscopic polypectomy (IT-EP) for difficult pedunculated colorectal polyps...

BACKGROUND: Several reports documented an inefficient utilisation of available resources, as well as a suboptimal compliance with surveillance recommendations. Although, evidence suggests that organisational issues can influence the quality of care delivered, surveillance protocols are usually based on non-organized approaches. METHODS: We conducted a literature search (publication date: 01/2000-06/2016) on PubMed and Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects and Cochrane Central Register of Controlled Trials for guidelines, or consensus statements, for surveys of practice, reporting information about patients, or providers attitudes and behaviours, for intervention studies to enhance compliance with guidelines...

Endoscopic resection (ER), including endoscopic polypectomy (EP), endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) are used to remove superficial neoplasms from the colon. Snare resection is used for EP and EMR, whereas endoscopic knives are used to perform dissection in the submucosal space in ESD. 80-90% colonic polyps are <10 millimetres (mm) and are effectively managed by conventional EP. Increasingly cold snare polypectomy is preferred. Large laterally spreading lesions (LSLs) and sessile polyps ≥20 mm are primarily removed by EMR...

Endoscopy is an inherent and an invaluable tool in every gastroenterologist's armamentarium. The prerequisite for quality and safety remains foremost. Adverse events should be minimized and proactive steps should taken before, during and after the endoscopic procedure. Upper endoscopy and colonoscopy are part of basic endoscopy and their major complications will be reviewed here, together with those of enteroscopy. The most common of all endoscopy related complications are cardiopulmonary and thus they will be addressed in detail first...

BACKGROUND: Sinonasal inverted papilloma is a locally aggressive tumor arising from the Schneiderian membrane which lines the nasal cavity and paranasal sinuses. Aggressive surgical approaches, such as lateral rhinotomy, were used until recently for complete removal of the inverted papilloma. Currently, endoscopic resection is the gold standard in the treatment of inverted papilloma. However, there are situations that justify an open approach. For example there are studies that report a higher postoperative recurrence rate after endonasal endoscopic resection, particularly in the treatment of recurrent diseases...
