Background and study aims Colonic polyps > 1 cm in size are commonly managed using hot polypectomy techniques. The most frequent adverse events (delayed bleeding, post-polypectomy syndrome, and perforation) are related to electrocautery-induced injury. We hypothesized that cold resection of large polyps may have similar efficacy and improved safety compared to hot polypectomy. Our aims were to evaluate efficacy and safety of piecemeal cold snare resection of colonic polyps > 1 cm. Patients and methods Patients undergoing lift and piecemeal cold snare polypectomy of non-pedunculated colon polyps > 1 cm from October 2013 to September 2015 were identified retrospectively...

A man aged 65 years presented with symptomatic anaemia without overt gastrointestinal bleeding. An oesophagogastroduodenoscopy (EGD) was performed and he was found to have a large ulcerated pedunculated Brunner's gland hamartoma in the duodenal bulb. The polyp was resected using snare cautery in forward and retroflexed positions. Colonoscopy was also performed and a few diminutive polyps were resected. A year later, the patient returned for a surveillance EGD, and no residual polyp was noted. Haemoglobin and iron studies normalised within a few months after polypectomy, with resolution of symptoms...

A colonic arteriovenous malformation (AVM) is a significant vascular lesion of the gastrointestinal tract and a common cause of lower gastrointestinal bleeding. AVMs are usually identified endoscopically as bright red, flat lesions. AVMs with a polypoid appearance are extremely rare in the large intestine. We present two cases of colonic polypoid AVM, which were detected incidentally during screening colonoscopy. Both the patients had no history of gastrointestinal bleeding such as melena or hematochezia. Colonoscopy revealed pedunculated polyps overlaid by hyperemic mucosa in the ascending colon and proximal sigmoid colon...

A 64-year-old woman underwent polypectomy for a rectal polyp(Isp). Pathological findings were invasion of the submucosa( 3,500 mm diameter), and she underwent anterior resection for rectal cancer(RS, pT1b, pN0, cM0, Stage I )without adjuvant chemotherapy. Lung masses were found in her right(8mm)and left lung(7mm). The tumors enlarged during the 4 month follow-up period. We decided to perform left partial pneumonectomy. The tumor was diagnosed as a lung metastasis from colon cancer by pathology. Because the right tumor was located towards the center, performing right pneumonectomy would have been quite invasive and we feared occult metastases...

We report a 27-year-old female who was diagnosed with adenocarcinoma of the uterine cervix associated with Peutz- Jeghers syndrome(PJS). She had undergone 5 surgeries for intestinal intussusception and had been diagnosed with PJS. She was referred to our hospital, complaining of watery vaginal discharge, and was diagnosed with adenocarcinoma of the uterine cervix. Following neoadjuvant chemotherapy, radical hysterectomy and small intestinal polypectomy by intraoperative endoscopy were performed. Among the third-degree relatives of her family, 10 had been diagnosed with PJS; of these 10, uterine cervical adenocarcinoma occurred in 3 relatives, pancreatic cancer in 2, cholangiocellular carcinoma in 1, and colon cancer in 1...

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...

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: 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...

REVIEW
Michael X Ma, Michael J Bourke
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...

BACKGROUND The aim of our study was to evaluate all lesions in the adenoma-dysplasia-cancer sequence of the colon and to examine whether the neutrophil-to-lymphocyte ratio (NLR) can distinguish polyps indicating dysplasia and cancer. MATERIAL AND METHODS A total of 397 patients who had colonoscopic polypectomy between January 2010 and December 2014 were included in our retrospective study. The patients were divided into four groups: patients with hyperplastic polyps, patients with adenomatous polyps, patients with dysplasia, and patients with cancer...

BACKGROUND: Although colonoscopy is generally a safe procedure, lethal complications can occur. Colonoscopic perforation is one of the most serious complications, and it can present with various clinical symptoms and signs. Aggravating abdominal pain and free air on simple radiography are representative clinical manifestations of colonoscopic perforation. However, unusual symptoms and signs, such as dyspnea and subcutaneous emphysema, which are less likely to be related with complicating colonoscopy, may obscure correct clinical diagnosis...

A 78-year-old woman who had recurrent right lower abdominal pain for about 1 year underwent computed tomography (CT) because of a follow-up observation 1 year after right breast cancer surgery. CT revealed a tumor in the colon. The patient was referred to our hospital for detailed examinations. An abdominal CT showed a low-density tumor of approximately 30 mm in the ascending colon, and the CT density inside the tumor was same as that of fatty tissues. A subsequent colonoscopy showed a submucosal tumor (SMT) in the proximal ascending colon developing from the terminal ileum...

OBJECTIVES: Post-polypectomy bleeding (PPB) is the most common complication of endoscopic procedures. To reduce the risk of thromboembolic incidents, Japanese guidelines for gastroenterological endoscopy were revised to indicate that antithrombotic agents were not to be discontinued for endoscopic treatment. However, performing endoscopic procedures under antithrombotic medication potentially increases the incidence of hemorrhagic complications. This study investigated the impact of the revised guidelines on the frequency of complications after colonoscopic procedures...
