Background/Aims: The removal of small colon polyps by hot snare polypectomy (HP) is a commonly used method. Polypectomy with a cold snare (CP) has been increasingly utilized in recent years. Each method has its own advantages and disadvantages. Herein, we explored the efficacy and safety of each method. Materials and Methods: Between January 1, 2012 and June 30, 2012, 97 consecutive patients with small colorectal polyps ranging from 5-9 mm in size were separated into either the CP or HP group. Demographic data, the duration of polypectomy, and pathology reports were recorded. Results: Seventy-seven polyps were removed from 49 patients in the CP group, and 71 polyps were removed from 48 patients in the HP group. There was no significant difference between the groups with respect to gender, age distribution, number of polyps, or indications for colonoscopy. The mean polyp size was 7.21±1.4 mm in the CP group and 7.56±1.45 mm in the HP group (p=0.111). There was a significant difference in the mean procedure time between the two groups (CP, 25.71±4.3 sec; HP, 70.28±11.3 sec, p<0.001). One patient (1.3/1.4%) from each group developed post-polypectomy bleeding that required treatment. Histological evaluation revealed that 10 of the polyps (6.75%) were advanced adenomas. Pathological examination showed that the polyps were not completely removed in 4 patients (5.13%) in the CP group and 4 patients (5.63%) in the HP group (p=0.89). Conclusion: CP is an effective and safe method that shortens the polypectomy duration in small polyps (≤9 mm) compared to HP.

Background/Aims: The frequency of gastric polyps increases with the widespread use of endoscopy for diagnosis and treatment. As gastric polyps can be malignant or premalignant, histopathological evaluation is needed. The aim of this study is to determine the prevalence and characteristics of gastric polyps in patients undergoing endoscopy. Materials and Methods: This study consisted of a retrospective analysis of 36650 consecutive endoscopy and associated pathology reports of 29940 patients between December 2005 and February 2012 in a tertiary-referral center. Results: Gastric polypoid lesions were detected in 666 (2.22%) patients. Hyperplastic polyps were the most common type of polyps (36.2%), followed by fundic gland polyps (8.3%), inflammatory fibroid polyps (2.4%) and adenomatous polyps (1.9%). Foveolar hyperplasia, neuroendocrine tumor, xanthoma, gastrointestinal stromal tumor, adenocarcinoma and lymphoma were less commonly seen. Malignant transformation was seen in 0.42% of hyperplastic polyps and in 23.1% of adenomatous polyps. Conclusion: Endoscopic appearance of gastric polyps can be variable, distinguishing macroscopically can be misleading. Because of their malignant potential histopathological evaluation is mandatory and polypectomy should be performed whenever possible.
It is recommended to investigate the serology of hepatitis B virus (HBV) and vaccinate seronegative patients at the time of diagnosis in inflammatory bowel diseases (IBD). This study aimed to investigate the efficacy of HBV vaccine and factors affecting the response.In this retrospective, observational study, HBV-seronegative IBD patients were administered 3 doses (at months 0, 1, and 6) recombinant 20 μg HbsAg. Patients’ demographics, IBD attributes, and treatment methods were investigated as the factors with potential impacts on vaccination outcomes.One hundred twenty-five patients with IBD were evaluated. The number of patients with Anti-HBs >10 IU/L was 71 (56.8%), and the number of patients with anti-HBs >100 IU/L was 50 (40%). Age, disease activity, Crohn disease subtype, and immunosuppressive treatment (IST) were found to have significant effects on immune response (P = 0.011, P < 0.001, P = 0.003, and P < 0.001, respectively). With multivariate analysis, age < 45 years (OR 3.1, 95% CI 1.2–8.3, P = 0.020), vaccination during remission (OR 5.6, 95% CI 2.3–14, P < 0.001), and non-IST (OR 11.1, 95% CI 2.9–43.2, P = 0.001) had favorable effects on the occurrence of adequate vaccine response.The likelihood of achieving adequate immune response with standard HBV vaccination protocol in IBD is low. Selecting vaccination protocols with more potent immunogenicity is a better approach to achieve effective vaccine response in patients with multiple unfavorable factors.
Endoscopic retrograde cholangiopancreatography is essential in the management of postoperative biliary leaks. Endoscopic sphincterotomy alone can be the initial procedure in the treatment of LGL from the CDS due to cholecystectomy.
Different methods such as standard, hot, and jumbo forceps are used in endoscopic treatment of diminutive colon polyps. In the current study, it was aimed to compare efficacy and safety of standard and jumbo forceps polypectomy methods in treatment of diminutive colon polyps of ≤5 mm. Polyps with ≤5 mm which were excised during colonoscopy by using standard or jumbo forceps were evaluated. Standard and jumbo forceps polypectomy methods were randomly performed in 212 consecutive patients with diminutive colorectal polyp. One-bite polypectomy and complete resection rates were also determined among polypectomy methods. Results of 161 standard forceps polypectomy and 102 jumbo forceps polypectomy were retrospectively evaluated. Both one-bite polypectomy and complete resection rates were significantly higher in the jumbo forceps polypectomy group than the standard forceps polypectomy group (P < 0.001). In the subgroup analysis performed according to polyp sizes, complete resection rate among polyps with 3mm diameter was determined as 100%. However, numbers of bites in 4-mm and 5-mm polyps were higher in the standard forceps polypectomy group, and complete resection rate was lower than in the jumbo forceps polypectomy group (P < 0.001). Both endoscopic treatment methods may be employed in treatment of diminutive colon polyps with ≤5 mm. However, jumbo forceps polypectomy is a more effective treatment method in 4- to 5-mm polyps with high one-bite polypectomy and complete resection rate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
