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...

Background and study aims: Endoscopic snare polypectomy with prophylactic detachable snare of large pedunculated colonic polyps (PCPs) is technically demanding. To facilitate removal of such polyps, we developed endoscopic resection using the Clutch Cutter and a detachable snare (ERCCDS). This study aimed to evaluate the efficacy and safety of the procedure. Patients and methods: From April 2010 to July 2015, 14 consecutive patients who had PCPs with head > 10 mm, stalk width > 5 mm, and stalk length > 10 mm were enrolled in this single-center prospective uncontrolled study...

BACKGROUND: Although colonoscopy with polypectomy can prevent up to 80% of colorectal cancers, a significant adenoma miss rate still exists, particularly in the right colon. Previous studies addressing right colon retroflexion have revealed discordant evidence regarding the benefit of this maneuver on adenoma detection with concomitant concerns about safety and rates of maneuver success. In this meta-analysis, we sought to determine the effect of right colon retroflexion on improving adenoma detection compared with conventional colonoscopy without retroflexion, as well as determine the rates of retroflexion maneuver success and adverse events...

BACKGROUND: Epithelial dysplasia and adenomatous polyps of colorectum are precancerous lesions. Surgical removal is still one of the important treatment approaches for colorectal polyps. CASE PRESENTATION: A male patient over 78 years was admitted due to bloody stool and abdominal pain. Colonoscopic biopsy showed a high-grade epithelial dysplasia in an adenomatous polyp of sigmoid colon. Anemia, COPD, ischemic heart disease (IHD), arrhythmias, and hypoproteinemia were comorbidities...

A 72-year-old man with the history of small bowel carcinoma was diagnosed to have a sessile polyp in the jejunum during a follow-up examination. We performed double-balloon endoscopy and removed the polyp by means of cold snare polypectomy. The follow-up endoscopy showed no residual lesion. Cold snare polypectomy has been established as a safe and effective method for the endoscopic treatment of colonic polyps with a low risk of causing electrocautery burns and perforation. However, this technique has not yet been applied for small bowel lesions...

INTRODUCTION: Several factors are used to stratify the probability of polyp recurrence. However, there are no studies correlating the location of the initial polyps and the recurrent ones. The aim of this study was to verify whether the polyp location at the surveillance colonoscopy was correlated with the location of the previously excised polyps at the baseline colonoscopy. METHODS: A retrospective study of patients submitted to colonoscopy with presence and excision of all polyps, followed by a surveillance colonoscopy...

BACKGROUND AND AIMS: Non-neoplastic polypectomies (NNP) add pathology and procedural costs but do not reduce cancer risk and should be minimized. We sought to define the minimal non-neoplastic polypectomy rate for those colonoscopists achieving high-quality colorectal cancer screening based on adenoma detection rates. METHODS: Non-neoplastic polypectomy rates (NNPR) for colonoscopists achieving high-quality adenoma detection rates (ADR) were reported to determine minimal NNPR goals...

BACKGROUND: Cold snare polypectomy (CSP) has been recently reported to be useful for the removal of small colonic polyps. However, the relationship between the histologically complete resection rate and snare size used during CSP has not been reported. Our aim was to assess the utility of CSP. METHODS: We analyzed the histologically complete resection rates and the frequency of complications for 175 colon polyps removed by CSP. Moreover, we examined the histologically complete resection rate associated with different snare sizes used during CSP...

PURPOSE: Polyps found during CT colonography can be removed by colonoscopic polypectomy. A colonoscope navigation system that navigates a physician to polyp positions while performing the colonoscopic polypectomy is required. Colonoscope tracking methods are essential for implementing colonoscope navigation systems. Previous colonoscope tracking methods have failed when the colon deforms during colonoscope insertions. This paper proposes a colonoscope tracking method that is robust against colon deformations...

AIM: Incomplete colonoscopy occurs in 8-10% of attempted examinations. An incomplete colonoscopy is usually followed by radiological evaluation of the large bowel to complete colonic assessment. Patients then found to have >1cm polyps represent a significant management dilemma. This study describes our experience using laparoscopy to facilitate complete colonoscopy and polypectomy in patients with fixed angulation and the success of subsequent colonoscopies. METHODS: All patients from 2008 to 2012 with an incomplete colonoscopy due to fixed angulation and polyps detected by subsequent imaging underwent standard laparoscopy with colonic mobilisation by division of adhesions to facilitate direct vision...

BACKGROUND: There is a continuing debate on the best approach for endoscopically benign large polyps that are unsuitable for conventional endoscopic resection. This study aimed to estimate the cancer risk in patients with endoscopically benign unresectable colonic polyps referred for surgery. STUDY DESIGN: We assessed patients with an endoscopic diagnosis of benign adenoma deemed not amenable to endoscopic removal, who underwent colectomy between 1997 and 2012. Patients with preoperative diagnoses of cancer, inherited polyposis syndrome, inflammatory bowel disease, and synchronous pathology requiring surgery were excluded...
