Jui-Hsiang Tang, Chi-Liang Cheng, Yen-Lin Kuo, Yi-Ning Tsui
BACKGROUND/AIMS: Same-day bidirectional endoscopy (BDE) is a commonly performed procedure, but the optimal sequence of the procedure with carbon dioxide insufflation is not well established. In this study, we investigated the optimal sequence for same-day BDE without polypectomy under moderate sedation and carbon dioxide insufflation in terms of sedation doses and colonoscopy performance. PATIENTS AND METHODS: We performed a prospective observational study of 63 asymptomatic patients who were admitted for physical check-ups...

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...

AIM: Laparoscopy is considered a good approach in treatment of colorectal neoplastic diseases; the endoscopic tattooing is then recommended (Evidence Level III and grade of recommendation A) to mark a lesion or a polypectomy site for intraoperative identification. We describe the case of perforation after tattoing treated conservatively. CASE REPORT: 63 years old woman, underwent colonoscopy for lipoma tattooing with India ink SPOT® solution kit and saline test...

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...

BACKGROUND: The recurrence rate after standard cold forceps polypectomy (CFP) of diminutive polyps of ≤5 mm has not been fully determined. The aim of this study was to analyze the long-term follow-up results and recurrence rate after CFP of diminutive polyps. METHODS: We retrospectively reviewed the medical records of 884 (738 men; age 53 years) asymptomatic subjects who underwent surveillance colonoscopy after CFP of 1-2 diminutive adenomatous polyps. Cumulative recurrence at the CFP site and risk factors for recurrence were analyzed...

AIM: To compare previously reported randomized controlled studies (RCTs) of cold and hot polypectomy, we systematically reviewed and clarify the utility of cold polypectomy over hot with respect to efficacy and adverse events. METHODS: A meta-analysis was conducted to evaluate the predominance of cold and hot polypectomy for removing colon polyps. Published articles and abstracts from worldwide conferences were searched using the keywords "cold polypectomy". RCTs that compared either or both the effects or adverse events of cold polypectomy with those of hot polypectomy were collected...

INTRODUCTION: Benign juvenile hamartomatous polyps are common in pediatric gastrointestinal practice. We hypothesize that in the absence of gross mucosal abnormalities, the likelihood of histologic abnormalities from routine random colonic biopsies is low. METHODS: We performed a retrospective chart review identifying patients aged 1 to 18 years who underwent complete colonoscopy and polypectomy for suspected colorectal polyps from January 1, 2004 to July 1, 2014...
