Abstract
Colonoscopy remains the primary method for preventing colorectal cancer. Traditionally, hot snare polypectomy (HSP) was the method of choice for removing polyps larger than 5 mm. Yet, for polyps smaller than 10 mm, cold snare polypectomy (CSP) has become the favored approach. Lately, the use of CSP has expanded to include the removal of sessile polyps that are between 10 and 20 mm in size. Our systematic review and meta-analysis aimed to evaluate the safety of cold snare polypectomy (CSP) compared to hot snare polypectomy (HSP) for resecting polyps measuring 10-20 mm. We searched the Medical Literature Analysis and Retrieval System Online (MEDLINE), Embase, and Cochrane databases up to April 2020 to find studies that directly compared CSP to HSP for polyps larger than 10 mm. Our main focus was on assessing the risk of delayed bleeding after polypectomy; a secondary focus was the incidence of any adverse events that required medical intervention post procedure. Our search yielded three comparative studies, two observational studies, and one randomized controlled trial (RCT), together encompassing 1,193 polypectomy procedures. Of these, 485 were performed using CSP and 708 with HSP. The pooled odds ratio (OR) for post-polypectomy bleeding (PPB) was 0.36 (95% confidence interval {CI}: 0.02, 7.13), with a Cochran Q test P-value of 0.11 and an I2 of 53%. For the risk of any adverse events necessitating medical care, the pooled OR was 0.15 (95% CI: 0.01, 2.29), with a Cochran Q test P-value of 0.21 and an I2 of 35%. The quality of the two observational studies was deemed moderate, and the RCT was only available in abstract form, preventing quality assessment. Our analysis suggests that there is no significant difference in the incidence of delayed post-polypectomy bleeding or other adverse events requiring medical attention between CSP and HSP for polyps measuring 10-20 mm.

Abstract
Colorectal cancer prevention has seen significant advancements with colonoscopic polypectomy, a critical technique in clinical practice. However, postpolypectomy bleeding (PPB), particularly in the resection of large pedunculated polyps, remains a major complication. This systematic review and meta-analysis investigates the efficacy of prophylactic epinephrine injections in preventing PPB, addressing inconsistencies in the literature regarding its effectiveness. Employing a comprehensive search strategy, we rigorously selected studies for inclusion, focusing on those comparing prophylactic epinephrine with no intervention. The risk of bias was assessed using the Cochrane Risk of Bias assessment tool, ensuring a robust and reliable analysis. Our findings, based on an analysis of four studies involving 1,062 patients, indicate a significant reduction in early PPB with epinephrine use, with a marked decrease in bleeding incidence compared to the no-prophylaxis group. However, the impact on delayed bleeding was less conclusive, suggesting the need for further research in this area. Our study thus highlights the effectiveness of epinephrine as a preventive tool in colonoscopic polypectomy while underscoring the complexity of bleeding risks and the necessity for ongoing investigation in optimizing patient outcomes.

Abstract
BACKGROUND Colorectal cancer is internationally the third leading cause of death from a malignant disease. The aim of screening colonoscopy in adults > 45 years of age is early diagnosis and treatment of precancerous polyps. Endoscopic polyp removal (polypectomy) can be achieved with various techniques depending on the size, morphology, and location of the polyp. According to current guidelines, small non-pedunculated polyps should be removed with a cold snare after the colorectal lumen has been insufflated with air (conventional cold snare polypectomy).In recent years, several studies have described the benefits of water aided colonoscopy, as well as the safety and efficacy of underwater cold snare polypectomy for large colon polyps. However, there are insufficient data on conventional and underwater techniques for small polyps, the most commonly diagnosed colorectal polyps. METHODS We have designed a prospective randomized double-blind clinical trial to compare the safety and efficacy of conventional and underwater cold snare polypectomy for non-pedunculated polyps 5-10 mm in size. A total of 398 polyps will be randomized. Randomization will be carried out using the random numbers method of Microsoft Excel 2016. The primary endpoint is the muscularis mucosa resection rate. Secondary endpoints are the depth and percentage of R0 excisions, complications, and the recurrence rate at follow-up endoscopy 6-12 months after polypectomy. DISCUSSION We hypothesize underwater polypectomy will result in a higher muscularis mucosa resection rate. The results of our study will provide useful data for the development of guidelines in polypectomy techniques for non-pedunculated polyps 5-10 mm in size.

Real-world local recurrence rate after cold polypectomy in colorectal polyps less than 10 mm using propensity score matching. World J Gastroenterol 2021; 27:8182-8193. [PMID: 35068862 PMCID: PMC8704276 DOI: 10.3748/wjg.v27.i47.8182] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Revised: 07/15/2021] [Accepted: 12/08/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Cold polypectomy (CP) is a simple and safe procedure for polyps less than 10 mm in size; however, there is concern about local recurrence following CP because of unidentified margins of excised specimens and the lack of tumor suppression effect by coagulation. Some clinical trials have evaluated local persistent recurrence; their results suggest that a higher rate of local recurrence has not been documented so far. There were few reports that observed the course over long periods of time after CP in clinical practice.
AIM To evaluate the presence of local recurrence following CP and hot polypectomy (HP) using propensity score matching.
METHODS We analyzed 275 patients who underwent polypectomy for non-pedunculated colorectal polyps less than 10 mm (959 Lesions) between October 2016 and 2017 and underwent follow-up endoscopy subsequently. We divided them into the CP group (706 Lesions), wherein CP was performed, and the HP group (253 Lesions), wherein HP was performed. Using propensity score matching, we extracted 215 Lesions in each group and evaluated the local recurrence and content of CP in the real clinic and adverse events using medical records.
RESULTS After propensity score matching, there were no significant differences in the patients’ and their endoscopic background (age, use of antithrombotics, indications, size, morphology, location of polyps, and polypectomy device) between the groups. The mean duration between colorectal polypectomy and the next follow-up colonoscopy was 17.5 ± 7.1 (range, 6-39) mo in the CP group and 15.7 ± 6.0 (range, 6-35) mo in the HP group, which was significantly longer in the CP group (P = 0.005). The local recurrence rate was 0.93% in the CP group and 0.93% in the HP group, without a significant difference (P = 0.688). Additionally, no differences were observed in the macroscopic en bloc resection rate, histopathological complete resection rate, and pathological results between the groups. Adverse events did not occur in either group.
CONCLUSION Local recurrence after CP was equivalent to that following HP in clinical practice. CP is useful and safe in the treatment of non-pedunculated polyps of less than 10 mm.

Abstract
BACKGROUND : Patients with end-stage renal disease (ESRD) have a higher incidence of clinically relevant complications, such as bleeding and perforation after polyp resection, compared to patients without underlying diseases. Cold snare polypectomy (CSP) is increasingly used for the removal of small polyps and diminutive polyps due to its shorter procedure time and low risk of bleeding and perforation. However, there have been few studies on the effectiveness and safety of CSP in patients with ESRD. The aim of this study was to compare the efficacy and safety of CSP and endoscopic mucosal resection (EMR) in ESRD patients. METHODS : This study was a retrospective study. We performed propensity score-matched analysis in patients with ESRD who underwent endoscopic resection for 3-10-mm-sized colorectal polyps at Seoul St. Mary's Hospital, from January 2014 to December 2019. RESULTS : After 1:1 ratio matching, 406 polyps were included: 203 polyps were resected with CSP and 203 polyps with EMR. There was no difference between the CSP group and EMR group in incomplete resection rate (4.43% vs. 1.97%, P = 0.16). There were no differences between the CSP and EMR group for immediate bleeding (5.42% vs. 7.88%, P = 0.32) and delayed bleeding (0% vs. 0.49%, P = 1.00). No perforation occurred in either group. CONCLUSIONS : There were no differences between the CSP and EMR group in terms of efficacy and safety. CSP can be one of the standard methods for the removal of 3-10-mm-sized colorectal polyps in patients with ESRD.

Abstract
BACKGROUND Underwater polypectomy without the need for submucosal injection has been reported. A heat-sink effect by immersing the polyp in water was proposed but no such experiment has been performed to support the claim. We compared the temperature rise on the serosal side during polypectomy between air- and water-filled colon. METHOD Freshly harvested porcine colons were placed in a metal tray with cautery electrode pad attached to its bottom. An upper endoscope was used with a cap and a rubber band mounted to the distal end. A mucosal site was randomly selected and identified on its serosal surface with a marker while suction was applied. Suction was applied again and a ligation band was applied to create a polyp. A cautery snare grasped the artificial polyp just below the band. An assistant placed the tip of a thermometer at the marked site on the serosal surface to record the baseline temperature before cautery and the highest temperature during polypectomy. Seven polypectomies in air and underwater were performed. RESULTS Mean (standard deviation) baseline temperature were 23.3 (0.6) °C and 23.4 (0.6) °C in the air and water groups, respectively. The maximum rise in temperature during polypectomy was 6.1 (4.5) °C and 1.4 (1.0) °C in the air and water groups, respectively (P = 0.004). CONCLUSIONS The maximum temperature rise during polypectomy was significantly less when polypectomy was performed underwater, supporting the hypothesis that a heat-sink effect does exist during underwater polypectomy.

Abstract
BACKGROUND AND AIMS Postpolypectomy bleeding is the most common adverse event with pedunculated polyps. We clarified the endoscopic characteristics influencing postpolypectomy bleeding for pedunculated colonic polyps. METHODS We reviewed clinical data for 1147 pedunculated colonic polyps removed by polypectomy in 5 Japanese institutions. Pedunculated polyps were defined as polyps with a stalk length ≥5 mm. Analyzed clinical data were age, sex, polyp location/size, stalk length/width, prophylactic clipping or endoloop before polypectomy, injecting the stalk, closing the polypectomy site, antithrombotic agent use, and endoscopist experience. Postpolypectomy bleeding was classified as immediate bleeding or delayed bleeding. RESULTS Immediate and delayed bleeding was observed in 8.5% (97/1147) and 2% (23/1147) of polypectomies, respectively. Comparing immediate bleeding with nonbleeding, multivariate analysis showed that stalk width ≥6 mm (odds ratio [OR], 1.9; 95% confidence interval [CI], 1.1-3.4) was a significant risk factor for immediate bleeding. For polyp size ≥15 mm, prophylactic endoloop use (OR, .17; 95% CI, .04-.72) was a significant inhibiting factor. Comparing delayed bleeding with nonbleeding, multivariate analysis showed that prophylactic clipping before polypectomy (OR, 4.2; 95% CI, 1.3-13) and injecting the stalk (OR, 4.0; 95% CI, 1.4-12) were significant risk factors for delayed bleeding. CONCLUSIONS The increased risk for delayed bleeding with injecting the stalk and prophylactic clipping before polypectomy suggests that simple resection with coagulation mode is a suitable strategy in endoscopic resection of pedunculated polyps. Moreover, prophylactic endoloop use was highly likely to inhibit immediate bleeding with polyp size ≥15 mm.

This is a collaboration between the British Society of Gastroenterology (BSG) and the European Society of Gastrointestinal Endoscopy (ESGE), and is a scheduled update of their 2016 guideline on endoscopy in patients on antiplatelet or anticoagulant therapy. The guideline development committee included representatives from the British Society of Haematology, the British Cardiovascular Intervention Society, and two patient representatives from the charities Anticoagulation UK and Thrombosis UK, as well as gastroenterologists. The process conformed to AGREE II principles and the quality of evidence and strength of recommendations were derived using GRADE methodology. Prior to submission for publication, consultation was made with all member societies of ESGE, including BSG. Evidence-based revisions have been made to the risk categories for endoscopic procedures, and to the categories for risks of thrombosis. In particular a more detailed risk analysis for atrial fibrillation has been employed, and the recommendations for direct oral anticoagulants have been strengthened in light of trial data published since the previous version. A section has been added on the management of patients presenting with acute GI haemorrhage. Important patient considerations are highlighted. Recommendations are based on the risk balance between thrombosis and haemorrhage in given situations.

Abstract
BACKGROUND AND AIMS Prophylactic clips to prevent delayed polypectomy bleeding (DPB) after endoscopic resection of large colorectal polyps remains controversial. We performed a systematic review and meta-analysis to evaluate the efficacy of prophylactic clips for preventing DPB by synthesizing the results of randomized trials. METHODS PubMed, Cochrane Library, and EMBASE were searched to October 2019 to identify randomized controlled trials evaluating the efficacy of placing prophylactic clips to reduce DPB after resection of large (≥10 mm) colorectal polyps. The primary outcome was DPB defined by GI bleeding after the conclusion of the colonoscopy. RESULTS Eight studies (n = 3415) met the study criteria, all with a low risk of bias. The overall pooled incidence of DPB was 3.9% (95% confidence interval [CI], 2.4%-5.4%) in patients receiving endoscopic resection of colorectal polyps ≥10 mm. Placing prophylactic clips reduced DPB in patients receiving prophylactic clips (relative risk [RR], 0.61; 95% CI, 0.43-0.85; I2 = 37.8%) compared with no clips with a number needed to treat (NNT) of 52 (95% CI, 31-163). In stratified analyses, placing clips was associated with reduced risks of DPB in patients with polyps ≥20 mm (RR, 0.54; 95% CI, 0.35-0.84; I2 = 0.0%; NNT, 30), nonpedunculated morphology (RR, 0.54; 95% CI, 0.36-0.81; I2 = 0.0%; NNT, 39), and located proximal to the hepatic flexure (RR, 0.49; 95% CI, 0.31-0.78; I2 = 54.8%; NNT, 25) compared with no clips. CONCLUSIONS Prophylactic clips after endoscopic resection of colorectal polyps ≥10 mm demonstrated a modest reduction in the risk of DPB. Larger reductions were observed in patients with polyps ≥20 mm, nonpedunculated morphology, or located proximal to the hepatic flexure.

Management and Outcomes of Bleeding Within 30 Days of Colonic Polypectomy in a Large, Real-Life, Multicenter Cohort Study. Clin Gastroenterol Hepatol 2021; 19:732-742.e6. [PMID: 32272252 DOI: 10.1016/j.cgh.2020.03.068] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/19/2019] [Revised: 03/17/2020] [Accepted: 03/22/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Management of delayed (within 30 days) postpolypectomy bleeding (DPPB) has not been standardized. Patients often undergo colonoscopies that do not provide any benefit. We aimed to identify factors associated with therapeutic intervention and active bleeding after DPPB. METHODS We performed a retrospective study of 548 patients with bleeding within 30 days after an index polypectomy (DPPB; 71.9% underwent colonoscopy, 2.6% underwent primary angiographic embolization, and 25.5% were managed without intervention) at 6 tertiary centers in Spain, from January 2010 through September 2018. We collected demographic and medical data from patients. The primary outcomes were the need for therapeutic intervention and the presence of active bleeding during colonoscopy. RESULTS A need for therapeutic intervention was associated independently with the use of antithrombotic agents, hemoglobin decrease greater than 2 g/dL, hemodynamic instability, and comorbidities (P < .05). The bleeding point during colonoscopy was identified in 344 patients; 74 of these patients (21.5%) had active bleeding. Active use of anticoagulants (odds ratio [OR], 2.6; 95% CI, 1.5-4.5), left-sided polyps (OR, 1.95; 95% CI, 1-3.8), prior use of electrocautery (OR, 2.6; 95% CI, 1.1-6.1), and pedunculated polyp morphology (OR, 1.8, 95% CI, 1-3.2) significantly increased the risk of encountering active bleeding. We developed a visual nomogram to estimate the risk of active bleeding. Overall, 43% of the cohort did not require any hemostatic therapy. Rebleeding (<6%) and transfusion requirements were low in those managed without intervention. CONCLUSIONS In a study of patients with DPPB, we found that almost half do not warrant any therapeutic intervention. Colonoscopy often is overused for patients with DPPB. We identified independent risk factors for active bleeding that might be used to identify patients most likely to benefit from colonoscopy.

Abstract
BACKGROUND/AIMS Few studies have examined the incidence of post-polypectomy bleeding (PPB) after discontinuation of antithrombotic therapies. Therefore, this study aimed to evaluate the incidence of PPB and thromboembolic events in patients whose antithrombotic agents were discontinued before colonoscopy. MATERIALS AND METHODS We retrospectively selected all patients who underwent colon polypectomy at a community hospital. A total of 282 patients (540 polypectomies) discontinued antithrombotic agents (group 1), and 1,648 patients (2,827 polypectomies) did not take antithrombotic agents (group 2). The cessation periods before and after polypectomies were 4 and 3 days for warfarin, 5 and 3 days for anti-platelet agents, and 7 and 5 days of combination therapy, respectively. Main outcome measurements were the incidence of PPB and thromboembolic events. RESULTS Immediate PPB rates were 3.9% (11/282) in group 1 and 4.6% (76/1648) in group 2 (adjusted odds ratio [OR], 0.85; 95% confidence interval [CI], 0.42-1.72; p=0.65). Delayed PPB rates were 1.4% (4/282) in group 1 and 1.1% (18/1648) in group 2 (adjusted OR, 1.24; 95% CI, 0.36-4.24; p=0.732). No thromboembolic events were observed in either group. CONCLUSION Our cessation periods were appropriate, and further shortening of these periods is possible.

Colonoscopic post-polypectomy bleeding in patients on uninterruptedclopidogrel therapy: A systematic review and meta-analysis. Exp Ther Med 2020; 19:3211-3218. [PMID: 32266017 PMCID: PMC7132234 DOI: 10.3892/etm.2020.8597] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2019] [Accepted: 10/25/2019] [Indexed: 02/07/2023] Open
Abstract
Current guidelines recommend temporary cessation of clopidogrel for 7-10 days for patients on clopidogrel undergoing colonoscopy with polypectomy. However, recent prospective randomized controlled trials have advocated for uninterrupted clopidogrel, due to similar post-polypectomy bleeding (PPB) rates with and without continued clopidogrel therapy. Thus, a meta-analysis was conducted to assess the risk of PPB rate in patients on continued clopidogrel therapy. Systemically identified publications were used to compare the rate of PPB in patients on continued clopidogrel therapy with those who had interrupted clopidogrel therapy. The primary outcome was the incidence of PPB. The secondary outcomes were immediate PPB, delayed PPB and serious cardio-thrombotic events. This study has been registered in PROSPERO (no. CRD42018118325). A total of five studies were identified, which included 655 patients in the continued clopidogrel group and 6620 patients in the control group. There was an increased risk of PPB with continued clopidogrel [P=0.0003; risk ratio (RR), 1.96; 95% confidence interval (CI), 1.36-2.83). The rate of immediate PPB was slightly higher in the continued clopidogrel group (5.77% vs. 1.77%, respectively), but was not statistically significant (P=0.06; RR, 1.57; 95%CI, 0.98-2.51). The rate of delayed PPB was increased in the continued clopidogrel group (P=0.0008; RR, 3.10; 95%CI, 1.60-5.98). However, no significant difference in serious cardio-thrombotic events was observed within 30 days (P=0.74; RR, 0.78; 95%CI, 0.18-3.40). Although continued clopidogrel therapy decreased the incidence of serious cardio-thrombotic events, the risk of delayed PPB was increased. Therefore, endoscopists should make all preparations to prevent bleeding in the perioperative period for patients at high thrombotic risk and on continued clopidogrel therapy, if polypectomy cannot be reasonably postponed.

Abstract
BACKGROUND Although prophylactic clip application before polypectomy may prevent postpolypectomy bleeding (PPB), the usefulness of prophylactic clipping in the treatment of large pedunculated polyps is controversial in some prospective randomized studies. This study was conducted to evaluate the efficacy of prophylactic clip application and to investigate the predictors of PPB in large pedunculated colorectal polyps. METHODS A total of 137 pedunculated polyps (size ≥1 cm) in 116 patients were prospectively included and randomized into group A (with clipping) and group B (without clipping), and resected. The occurrences of immediate PPB (graded 1-4) and delayed PPB were compared. RESULTS Sixty-seven polyps were allocated in group A and 70 polyps in group B. In both groups, the median polyp diameter was 15 mm (P = 0.173) and the median stalk diameter was 3 mm (P = 0.362). Twenty-eight (20.4%) immediate PPB episodes in 137 polyps occurred, 6 (9.0%) in group A and 22 (31.4%) in group B (P = 0.001). However, the occurrence of delayed PPB was not different between the groups (P = 0.943). Prophylactic clip application decreased the occurrence of immediate PPB (odds ratio 0.215, 95% confidence interval 0.081-0.571). Moreover, polyp size ≥20 mm and stalk diameter ≥ 4 mm increased the risk of immediate PPB. CONCLUSIONS Clip application before polypectomy of ≥1 cm pedunculated polyps is effective in decreasing the occurrence of immediate PPB. Thus, clip application should be considered before performing snare polypectomy, especially for large polyps with a thick stalk. TRIAL REGISTRATION This research was studied a prospective maneuver and enrolled in a registry of clinical trials run by United States National Library of Medicine at the National Institutes of Health (ClinicalTrials.gov Protocol Registration and Results system ID: NCT01437631). This study was registered on September 19, 2011.

Abstract
These consensus guidelines were jointly commissioned by the British Society of Gastroenterology (BSG), the Association of Coloproctology of Great Britain and Ireland (ACPGBI) and Public Health England (PHE). They provide an evidence-based framework for the use of surveillance colonoscopy and non-colonoscopic colorectal imaging in people aged 18 years and over. They are the first guidelines that take into account the introduction of national bowel cancer screening. For the first time, they also incorporate surveillance of patients following resection of either adenomatous or serrated polyps and also post-colorectal cancer resection. They are primarily aimed at healthcare professionals, and aim to address:Which patients should commence surveillance post-polypectomy and post-cancer resection?What is the appropriate surveillance interval?When can surveillance be stopped? two or more premalignant polyps including at least one advanced colorectal polyp (defined as a serrated polyp of at least 10 mm in size or containing any grade of dysplasia, or an adenoma of at least 10 mm in size or containing high-grade dysplasia); or five or more premalignant polyps The Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument provided a methodological framework for the guidelines. The BSG's guideline development process was used, which is National Institute for Health and Care Excellence (NICE) compliant.two or more premalignant polyps including at least one advanced colorectal polyp (defined as a serrated polyp of at least 10 mm in size or containing any grade of dysplasia, or an adenoma of at least 10 mm in size or containing high-grade dysplasia); or five or more premalignant polyps The key recommendations are that the high-risk criteria for future colorectal cancer (CRC) following polypectomy comprise either:two or more premalignant polyps including at least one advanced colorectal polyp (defined as a serrated polyp of at least 10 mm in size or containing any grade of dysplasia, or an adenoma of at least 10 mm in size or containing high-grade dysplasia); or five or more premalignant polyps This cohort should undergo a one-off surveillance colonoscopy at 3 years. Post-CRC resection patients should undergo a 1 year clearance colonoscopy, then a surveillance colonoscopy after 3 more years.

Prophylactic endoscopic coagulation to prevent delayed post-EMR bleeding in the colorectum: a prospective randomized controlled trial (with videos). Gastrointest Endosc 2019; 90:813-822. [PMID: 31175874 DOI: 10.1016/j.gie.2019.05.039] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2018] [Accepted: 05/27/2019] [Indexed: 12/11/2022]
Abstract
BACKGROUND AND AIMS Post-EMR bleeding (PEB) is the most common adverse event after EMR. However, there are no established endoscopic methods for the prevention of PEB. This study aimed to investigate whether prophylactic endoscopic coagulation (PEC) using coagulation probes reduces the incidence of overall delayed PEB. METHODS We performed a randomized controlled study of patients undergoing EMR for large (≥10 mm) sessile lesions and laterally spreading tumors. Patients were randomized 1:1 to the EMR with coagulation group (n = 285) or EMR (control) group (n = 285). Immediate bleeding during colon EMR or clean-based ulcer after EMR was excluded. Clinically significant PEB was defined as bleeding requiring endoscopic hemostasis, hospitalization, or a decrease in the hemoglobin level >2 g/dL. RESULTS A total of 569 patients were analyzed. The incidence of overall PEB was significantly lower in the EMR with coagulation group than in the control group (12.6% [36/285] vs 18.7% [53/284], P = .048). However, this was largely because of a reduction in minor bleeding. There was no difference in clinically significant PEB (1.8% [5/285] vs 3.2% [9/284], P = .276). Rectal location was a risk factor associated with overall PEB (odds ratio, 1.256; 95% confidence interval, 1.12-1.41; P < .001). CONCLUSIONS Although this study found reduced PEB with prophylactic cautery of visible vessels, this was largely because of a reduction in minor bleeding with no benefit observed for clinically significant bleeding. Overall, PEB was more frequent with rectal lesions. (Clinical trial registration number: KCT0000779.).

Ket SN, Mangira D, Ng A, Tjandra D, Koo JH, La Nauze R, Metz A, Moss A, Brown G. Complications of cold versus hot snare polypectomy of 10-20 mm polyps: A retrospective cohort study. JGH OPEN 2019; 4:172-177. [PMID: 32280761 PMCID: PMC7144768 DOI: 10.1002/jgh3.12243] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/20/2019] [Revised: 05/25/2019] [Accepted: 06/25/2019] [Indexed: 02/06/2023]
Abstract
Background and Aim Cold snare polypectomy is safe and efficacious for removing polyps <10 mm with reduced rates of delayed postpolypectomy bleeding and postpolypectomy syndrome. This technique can also be used for sessile polyps ≥10 mm; however, further evidence is required to establish its safety. The aim of this study was to compare intraprocedure and postprocedure adverse events in patients who underwent cold (CSP) versus hot snare polypectomy (HSP) of 10-20 mm sessile colonic polyps. Methods Electronic medical records and endoscopy reports of all patients who underwent polypectomy for Paris 0-IIa, Is, or 0-IIa + Is 10-20 mm colonic polyps between January 2015 and June 2017 at three tertiary academic hospitals and one private hospital were retrospectively reviewed. Data on patient demographics, polyp characteristics, method of polypectomy, and intraprocedural and postpolypectomy adverse events were collected. Results A total of 408 patients (median age 67, 50% male) had 604 polyps, 10-20 mm in size, removed. Of these, 258 polyps were removed by HSP, with a median size of 15 mm (interquartile range [IQR] 12-20), compared to 346 polyps that were removed by CSP, with median size of 12 mm (IQR 10-15), P < 0.001. In the HSP group, 15 patients presented with postprocedure complications, including 11 with clinically significant bleeding, 2 with postpolypectomy syndrome, and 2 with abdominal pain. This compares with no postpolypectomy complications in the CSP group, P < 0.001. Conclusion In this study, CSP was not associated with any postpolypectomy adverse events. CSP appears to be safer than HSP for removing 10-20 mm-sized sessile polyps. A prospective multicenter study has been commenced to verify these findings and to assess the efficacy of CSP for the complete resection of polyps of this size.

Effect of prophylactic clip placement following endoscopic mucosal resection of large colorectal lesions on delayed polypectomy bleeding: A meta-analysis. World J Gastroenterol 2019; 25:2251-2263. [PMID: 31143075 PMCID: PMC6526150 DOI: 10.3748/wjg.v25.i18.2251] [Citation(s) in RCA: 31] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2019] [Revised: 03/22/2019] [Accepted: 05/03/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The role of prophylactic clipping for the prevention of delayed polypectomy bleeding (DPB) remains unclear and conclusions from prior meta-analyses are limited due to the inclusion of variety of resection techniques and polyp sizes.
AIM To conduct a meta-analysis on the effect of clipping on DPB following endoscopic mucosal resection (EMR) of colorectal lesions ≥ 20 mm.
METHODS We performed a search of PubMed and the Cochrane library for studies comparing the effect of clipping vs no clipping on DPB following endoscopic resection. The Cochran Q test and I2 were used to test for heterogeneity. Pooling was conducted using a random-effects model.
RESULTS Thirteen studies with a total of 7794 polyps were identified, of which data was available on 1701 cases of EMR of lesions ≥ 20 mm. Prophylactic clipping was associated with a lower rate of DPB (1.4%) when compared to no clipping (5.2%) (pooled OR: 0.24, 95%CI: 0.12-0.50, P < 0.001) following EMR of lesions ≥ 20 mm. There was no significant heterogeneity among the studies (I2 = 0%, P = 0.67).
CONLUSION Prophylactic clipping may reduce DPB following EMR of large colorectal lesions. Future trials are needed to further identify risk factors and stratify high risk cases in order to implement a cost-effective preventive strategy.

Abstract
Background and Aims: Postpolypectomy bleeding and incomplete polyp removal are important complication and quality concerns of colonoscopy for colon cancer prevention. We investigated if endoscopic mucosal stripping (EMS) as a technical modification of traditional cold snare polypectomy to avoid submucosal injury during removal of non-pedunculated colon polyps could prevent postpolypectomy bleeding and facilitate complete polyp removal. Methods: This is an Internal Review Board exemption-granted retrospective analysis of 5,142 colonoscopies with snare polypectomy performed by one of the authors (ZJC) at Minnesota Gastroenterology ambulatory endoscopy centers during a 12-year period divided into pre-EMS era (2005–2012, n = 2,973) and EMS era (2013–2016, n = 2169) with systemic adoption of EMS starting 2013. Change in postpolypectomy bleeding rate before and after EMS adoption and EMS polypectomy completeness were evaluated. Results: Zero postpolypectomy bleeding case was found during EMS era (rate 0%) compared with 10 bleeding cases during pre-EMS era (rate 0.336%). This difference was statistically significant (P = 0.0055) and remained so after excluding 2 bleeding cases of pedunculated polyps (P = 0.012). All bleeding cases involved hot snare polypectomy. Histological examination of the involved polyps showed substantial submucosal vascular damage in contrast to a remarkable paucity of submucosa in comparable advanced polyps removed using EMS. Both biopsy and follow-up colonoscopy examination of the polypectomy sites confirmed that EMS more completely removed non-pedunculated advanced polyps. Conclusions: EMS polypectomy was effective in preventing postpolypectomy bleeding and facilitated complete polyp removal.

Abstract
Delayed postpolypectomy bleeding (DPPB) is the most common complication of colonoscopic polypectomy. Prophylactic clipping after an uncomplicated polypectomy is increasingly used, but it is unclear if this results in the prevention of DPPB. This study aimed to review prophylactic clip use and its effect on the rates of DPPB. MEDLINE, Embase, and the Cochran Library were systematically searched for studies (1995–March 2017) that used prophylactic hemoclips and assessed DPPB as an outcome. Of 1402 articles identified, nine papers were eligible for inclusion, evaluating 4311 patients and 7783 polyps; 118 patients experienced a DPPB, and 49 of these patients received prophylactic clips. There was no significant difference in DPPB rates in patients who received prophylactic clipping compared to those who did not (odd ratio: 0.8; 95% confidence interval: 0.36–1.77; P = 0.56). There was also no significant difference in the DPPB of polyps <20 mm compared with polyps ≥20 mm. Clip application for prophylactic management of an uncomplicated polypectomy has not been demonstrated to reduce the risk of DPPB, casting doubt on the use of this costly practice.

Abstract
Lower gastrointestinal bleeding (LGIB) is a common cause of presentation to the emergency department and hospital admissions. The incidence of LGIB increases with age and the most common etiologies are diverticulosis, angiodysplasia, malignancy and anorectal diseases. Foremost modality for evaluation and treatment of LGIB is colonosopy. Other diagnostic tools such as nuclear scintigraphy, computed tomography, angiography and capsule endoscopy are also frequently used in the workup of LGIB. Choice of treatment modality depends on the hemodynamic status of the patient, rate of bleeding, expertise and available resources. We present a comprehensive review of the evaluation and management of LGIB.

Abstract
BACKGROUND Patients receiving direct-acting, non-vitamin K oral anticoagulants (NOAC) frequently undergo gastrointestinal endoscopies (GIE) but little is known on the management and outcome of these interventions. METHODS With use of data from an ongoing, prospective, noninterventional registry of NOAC patients, the management and outcome of GIE were evaluated with use of standard event definitions. Patients undergoing GIE were categorized into two subgroups: (1) scheduled GIE (scheduled appointment, no acute bleeding) and (2) unscheduled GIE (unscheduled including management of acute gastrointestinal bleeding). The rates of major bleeding complications, cardiovascular complications, and all-cause death within 30 days after the procedure were evaluated. RESULTS Between October 1, 2011, and March 31, 2015, 492 patients underwent a total of 713 GIE (44.5% gastroscopies, 53.0% colonoscopies, 2.5% endoscopic retrograde cholangiopancreatography procedures), with 70.0% being scheduled procedures and 30.0% being unscheduled procedures. Endoscopies were performed within 24 h after the last NOAC intake in 45 of 713 cases (6.3%), between 24 and 48 h after the last intake in 336 cases (47.1%), and after NOAC therapy interruption for more than 48 h in 213 cases (29.9%). Heparin bridging therapy was used in 180 of 713 procedures (25.3%) and predominantly (170/180; 94.4%) in cases of NOAC therapy interruption for longer than 72 h. Until day 30 after the procedure, the event rates were 1.4% for cardiovascular events and 0.7% for major bleeding events. CONCLUSION Continuation or short-term interruption of NOAC therapy seems to be a safe strategy for GIE. Heparin bridging therapy is predominantly used in cases of prolonged NOAC therapy interruption.

Abstract
Background Screening by means of biennial fecal occult blood test has provided a reduction in overall colorectal cancer mortality. Notwithstanding, we should not underestimate the harms that it can produce. Aim The aim of this article is to identify the independent risk factors of complications after a screening colonoscopy. Methods A six-year, nested case-control study was conducted. Mortality/complications within 30 days after colonoscopy were registered and its predictors identified through logistic regression. Results After 39,254 colonoscopies, the complication rate was 1.0%. Independent predictors were sex (OR 1.68 for men; CI 95% 1.18-2.39), ASA physical status classification system (OR 1.73 for ASA II-III; CI 95% 1.53-3.69), history of abdominal surgery (OR 2.37; CI 95% 1.72-4.08), diverticulosis (OR 2.89; CI 95% 1.94-4.30), inadequate cleansing (OR 29.35; CI 95% 6.52-132.17), detection of advanced neoplasia (AN) (OR 4.92; CI 95% 3.29-7.36), detection of stage I adenocarcinoma (OR 9.44; CI 95% 4.46-20.0), polyps in right colon OR 2.27 CI 95% 1.38-3.74) and complex polypectomy (OR 2.00; CI 95% 1.25-3.20). The logistic model explained 82% of the complications (CI 95% 0.798-0.854, p < 0.001). Conclusions Colonoscopy, with or without removal of a lesion, is an invasive procedure with a non-deniable risk of major complications. Factors like inadequate cleansing or detection of AN are determinants. Therefore, it is vital to know which aspects predict their appearance to implement countermeasures.

Abstract
BACKGROUND AND AIM Peri-procedural bridging (PPB) with heparin is recommended for patients with high thromboembolic risk who need to withhold antithrombotic therapy for colonoscopic polypectomy. However, little is known about the bleeding risk from heparin-bridging therapy itself. METHODS MEDLINE and EMBASE databases were searched through January 2017 for studies that compared the risk of PPB in patients who received heparin-bridging therapy in lieu of antithrombotic agents for colonoscopic polypectomy and those who discontinued antithrombotic agents without receiving heparin. Pooled odds ratio (OR) and 95% confidence interval (CI) were calculated using a random-effects model, generic inverse variance method. Between-study heterogeneity was quantified using the Q statistic and I2 . RESULTS A total of five studies consisting of 2601 patients were identified. A significantly increased risk of PPB among bridged patients compared to non-bridged patients was demonstrated with a pooled OR of 8.29 (95% CI, 4.96-13.87). Statistical heterogeneity was low with I2 of 0%. CONCLUSION The present study demonstrated a significantly increased risk of PPB among patients who underwent colonoscopic polypectomy and received heparin-bridging therapy in lieu of antithrombotic agents compared to patients who did not receive it.

Abstract
BACKGROUND AND AIM Bleeding is the most common adverse event following colonoscopic endoscopic mucosal resection (EMR). We aimed to assess the clinical outcomes of a colon EMR according to the post-EMR ulcer status and determine the risk factors of delayed postpolypectomy bleeding (DPPB) based on the post-EMR ulcer status. METHODS The medical records and endoscopic images of patients who underwent EMR of colon polyps with diameters of ≥ 5 mm were retrospectively reviewed by us. If any exposed vessels were observed on the post-EMR ulcer, the types of exposed vessels were classified into cut and uncut vessels. The coagulation injuries on the post-EMR ulcer were categorized as grades 1, 2, or 3. RESULTS In total, 505 patients with 728 polyps were examined. Exposed vessels were present in 416 post-EMR ulcers, including cut vessels in 11 (1.5%) and uncut vessels in 405 (55.6%). With regard to coagulation injury, 113 (15.5%), 443 (60.9%), and 172 (23.6%) post-EMR ulcers had grades 1, 2, and 3 injuries, respectively. DPPB was observed in 20 lesions (2.7%). Multivariate analysis indicated that a polyp size > 10 mm (odds ratio [OR], 3.354; 95% confidence interval [CI], 1.229-9.154), cut vessels (OR, 18.913; 95% CI, 3.106-115.187), and grade 3 coagulation injury (OR, 16.796; 95% CI, 1.825-154.556) were associated with DPPB. CONCLUSIONS Cut vessels and severe coagulation injury on post-EMR ulcers, as well as larger polyp size, are risk factors for DPPB. Careful inspection of post-EMR ulcers and prophylactic hemostasis, if necessary, may improve the clinical outcomes of colonoscopic EMR.

Abstract
PURPOSE Delayed post-polypectomy bleeding (PPB) is an infrequent but serious adverse event after colonoscopic polypectomy. Several studies have tried to identify risk factors for delayed PPB, with inconsistent results. This meta-analysis aims to identify significant risk factors for delayed PPB. METHODS MEDLINE and EMBASE databases were searched through January 2016 for studies that investigated the risk factors for delayed PPB. Pooled odds ratio (OR) for categorical variables and mean differences (MD) for continuous variables and 95% confidence interval (CI) were calculated using a random-effect model, generic inverse variance method. The between-study heterogeneity of effect size was quantified using the Q statistic and I 2. RESULTS Twelve articles involving 14,313 patients were included. The pooled delayed PPB rate was 1.5% (95%CI, 0.7-3.4%), I 2 = 96%. Cardiovascular disease (OR = 1.55), hypertension (OR = 1.53), polyp size > 10 mm (OR = 3.41), and polyps located in the right colon (OR = 1.60) were identified as significant risk factors for delayed PPB, whereas age, sex, alcohol use, smoking, diabetes, cerebrovascular disease, pedunculated morphology, and carcinoma histology were not. CONCLUSIONS Cardiovascular disease, hypertension, polyp size, and polyp location were associated with delayed PPB. More caution is needed when removing polyps in patients with these risk factors. Future studies are warranted to determine appropriate preventive hemostatic measures in these patients.

Feagins LA. Management of Anticoagulants and Antiplatelet Agents During Colonoscopy. Am J Med 2017; 130:786-795. [PMID: 28344132 DOI: 10.1016/j.amjmed.2017.01.052] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2017] [Revised: 01/31/2017] [Accepted: 01/31/2017] [Indexed: 01/14/2023]
Abstract
Colonoscopy frequently is performed for patients who are taking aspirin, nonsteroidal anti-inflammatory drugs, antiplatelet agents, and other anticoagulants. These colonoscopies often involve polypectomy, which can be complicated by bleeding. The risks of precipitating thromboembolic complications if anticoagulants are stopped must be weighed against the risk of postpolypectomy bleeding if these agents are continued. This article systematically reviews the management of anticoagulation during elective and emergency colonoscopy. For patients undergoing colonoscopic polypectomy, the overall risk of postpolypectomy bleeding is <0.5%. Risk factors for postpolypectomy bleeding include large polyp size and anticoagulant use, especially warfarin and thienopyridines. For patients who do not stop aspirin or other nonsteroidal anti-inflammatory drugs prior to colonoscopy, the rate of postpolypectomy bleeding is not significantly different from that for patients who do not take those medications. For patients who continue thienopyridines and undergo polypectomy, the risk of delayed postpolypectomy bleeding is approximately 2.4%. Even for patients who interrupt warfarin, the risk of postpolypectomy bleeding is increased. The direct oral anticoagulants (direct thrombin inhibitors and factor Xa inhibitors) have a rapid onset and offset of action, and periprocedural bridging generally is not necessary. For the thienopyridines, warfarin, and the direct oral anticoagulants, the decision to interrupt or continue these agents for endoscopy will involve considerable exercise of clinical judgment.

Efficacy of submucosal epinephrine injection for the prevention of postpolypectomy bleeding: A meta-analysis of randomized controlled studies. Ann Med Surg (Lond) 2017; 19:65-73. [PMID: 28652912 PMCID: PMC5476974 DOI: 10.1016/j.amsu.2017.05.035] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2017] [Revised: 05/29/2017] [Accepted: 05/29/2017] [Indexed: 12/11/2022] Open
Abstract
Background Bleeding is the most common major complication following colonoscopic polypectomy. The purpose of this study is to evaluate whether submucosal epinephrine injections could prevent the occurrence of postpolypectomy bleeding. Method The dataset was defined by searching PubMed, EMBASE, Google Scholar, and the Cochrane database for appropriate randomized controlled studies published before April 2015. A meta-analysis was conducted to investigate the preventative effect of submucosal epinephrine injection for overall, early, and delayed postpolypectomy bleeding. Results The final analysis examined the findings of six studies, with data from 1388 patients. The results demonstrated that prophylactic treatment with epinephrine injection significantly reduced the occurrence of overall (OR = 0.38, 95% CI: 0.21, 0.66; p = 0.0006) and early bleeding (OR = 0.38, 95% CI: 0.20, 0.69; p = 0.002). However, for delayed bleeding complications, epinephrine injections were not found to be any more effective than treatment with saline injection or no injection (OR = 0.45, 95% CI: 0.11, 1.81; p = 0.26). Moreover, for patients with polyps larger than 20 mm, mechanical hemostasis devices (endoloops or clips) were found to be more effective than epinephrine injection in preventing overall bleeding (OR = 0.33, 95% CI: 0.13, 0.87; p = 0.03) and early bleeding (OR = 0.29, 95% CI: 0.08, 1.02; p = 0.05). This was not established for delayed bleeding. Conclusion The routine use of prophylaxis submucosal epinephrine injection is safe and beneficial preventing postpolypectomy bleeding.

Abstract
OPINION STATEMENT Management of patients on anticoagulant or antiplatelet therapy undergoing endoscopy presents a balance of risks between haemorrhage due to the procedure, and thrombosis due to discontinuation of antithrombotic therapy. Haemorrhage is usually controllable endoscopically, but thrombosis could, on occasion, result in myocardial infarction or stroke, with permanent disability or death. For elective procedures, there is adequate time to plan best management of antithrombotic therapy. International guidelines have been published, but recommendations are based on limited evidence and consultation with appropriate medical specialists, and the patient is important. Patients on dual antiplatelet therapy for coronary stents are at particularly high risk of thrombosis if therapy is interrupted. Direct oral anticoagulants have been a great advance in the management of anticoagulation but can present an increased risk of spontaneous gastrointestinal haemorrhage, as well as a difficult management situation in haemorrhage following endoscopic therapy. For elective endoscopic procedures, there may be a suitable alternative investigation, and some patients can have therapy deferred if high-risk antithrombotic therapy is temporary. Gastrointestinal haemorrhage on antithrombotic therapy can present a life-threatening situation from potential thrombosis as well as haemorrhage. Management is particularly challenging on direct oral anticoagulants (DOACs), but a reversal agent is available for dabigatran, and others are in development. The safest time to restart antithrombotic therapy after therapeutic procedures or haemorrhage has been little studied, and the relevant risk factors are discussed together with advice on management. Although guidelines have been produced, there remains much uncertainty in the management of antithrombotic therapy for endoscopy, particularly for newer agents, and further research is required.

Abstract
Background/Aims The clinical course after endoscopic management of delayed postpolypectomy bleeding (DPPB) has not been clearly determined. This study aimed to assess clinical outcomes after endoscopic hemostasis of DPPB and evaluate risk factors for rebleeding after initial hemostasis. Methods We reviewed medical records of 198 patients who developed DPPB and underwent endoscopic hemostasis between January 2010 and February 2015. The performance of endoscopic hemostasis was assessed. Rebleeding negative and positive patients were compared. Results DPPB developed 1.4±1.6 days after colonoscopic polypectomy. All patients achieved initial hemostasis. Clipping was the most commonly used technique. Of 198 DPPB patients, 15 (7.6%) had rebleeding 3.3±2.5 days after initial hemostasis. The number of clips required for hemostasis was higher in the rebleeding positive group (3.2±1.6 vs. 4.2±1.9, P=0.047). Combinations of clipping with other modalities such as injection methods were more common in the rebleeding positive group (67/291, 23.0% vs. 12/17, 70.6%; P<0.001). Multivariate analysis showed a large number of clips and combination therapy were independent risk factors for rebleeding. All the rebleeding cases were successfully managed by repeat endoscopic hemostasis. Conclusions Endoscopic hemostasis is effective for the management of DPPB because of its high initial hemostasis rate and low rebleeding rate. Endoscopists should carefully observe patients in whom a large number of clips and/or combination therapy have been used to manage DPPB because these may be related to the severity of DPPB and a higher risk of rebleeding.

Abstract
BACKGROUND AND AIM 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, carrying out endoscopic procedures under antithrombotic medication potentially increases the incidence of hemorrhagic complications. The present study investigated the impact of the revised guidelines on the frequency of complications after colonoscopic procedures. METHODS The surveillance period comprised the year before the initiation of the new guidelines (2012), which served as a control period, and 2 years after initiation of the new guidelines (2013 and 2014). During the control period, 3955 cases were examined colonoscopically and 1601 lesions were treated endoscopically. During the 2-year period under the new guidelines, 8749 colonoscopies and 3768 endoscopic treatments were carried out. Changes in treatment methods and rates of complications were compared. RESULTS PPB rate was not significantly different before and after the revision (0.87% vs 1.01%). With the new guidelines, PPB rates in antithrombotic non-users and users were 0.60% and 3.13%, respectively (OR 5.11, P = 0.000). Multivariable analysis showed that the risks for PPB were as follows: heparin bridging therapy (OR 6.34, P = 0.0002); low-dose aspirin (LDA) continuation (OR 5.30, P = 0.0079); and lesion size (OR 1.06, P < 0.0001). CONCLUSION The present study showed that the overall PPB rate under the new guidelines was not significantly higher when compared with the previous data obtained before the new guidelines were introduced.

Abstract
BACKGROUND AND AIM Evidence regarding safety and efficacy of heparin-bridging therapy for colonoscopic polypectomy remains scarce. The aim of the present study was to evaluate the risk of post-polypectomy bleeding (PPB) in patients receiving heparin-bridging therapy. METHODS We retrospectively reviewed the database of patients who underwent colonoscopic polypectomy with prophylactic clip closure between January 2007 and December 2014 at our institution. We evaluated patients receiving heparin-bridging therapy (HB group) compared with those who did not receive antithrombotic therapy (No-HB group). RESULTS A total of 1421 polypectomies were carried out on 773 patients; 45 patients were in the HB group and 728 patients were in the No-HB group. The incidence of PPB per patient was significantly higher in the HB group (22.2% vs 1.9%, P < 0.0001), and multivariate analysis showed that heparin-bridging therapy was an independent risk factor for PPB (OR 9.80, 95% CI 4.23-22.3, P < 0.0001). In the HB group, the polyp size was not a risk factor for PPB (OR 0.67, 95% CI 0.19-2.26, P = 0.55); the incidence of PPB in lesions of <10 mm and ≥10 mm in size was 14.6% and 10.2% respectively. In contrast, that was a significant risk factor in the No-HB group (OR 4.71, 95% CI 1.41-21.3, P = 0.011). Activated partial thromboplastin time and international normalized ratio were in or under the therapeutic range in the HB group when PPB occurred. CONCLUSIONS Heparin-bridging therapy is associated with a high risk of PPB regardless of polyp size.

Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) is a curative, standard therapy for colorectal neoplasms. Some studies have investigated the risk factors for perforation during colorectal ESD. However, few studies have assessed the risk factors for delayed bleeding after colorectal ESD. We studied patients undergoing ESD for colorectal epithelial neoplasms to identify the risk factors for post-ESD bleeding. PATIENTS AND METHODS We studied 124 consecutive patients undergoing ESD for colorectal epithelial neoplasms. To identify risk factors for delayed bleeding post-ESD, recurrent bleeding post-ESD was compared with patient-related and tumor-related factors. RESULTS Delayed bleeding after ESD occurred in 10 (8.1%) lesions of 124 colorectal tumors, and the median time from the end of ESD to the onset of bleeding was 18.5 h. Delayed bleeding was significantly higher in tumors located in rectums than in colons (P=0.021), and the number of occurrences of arterial bleeding during ESD was significantly higher in the delayed bleeding group than in the nondelayed bleeding group (P=0.002). The procedure time was significantly longer in the delayed bleeding group than in the nondelayed bleeding group (P=0.012). On multivariate logistic regression analysis, tumor location (odds ratio, 10.13; 95% confidence interval, 1.18-87.03; P=0.035) and three or more occurrences of arterial bleeding during ESD (odds ratio, 6.86; 95% confidence interval, 1.13-41.5; P=0.036) were significant independent risk factors for delayed bleeding. CONCLUSION The presence of lesions in the rectum and three or more arterial bleeding occurrences during ESD were risk factors for post-ESD bleeding. Patients with these risk factors should be followed up carefully after ESD for colorectal epithelial neoplasms.

Abstract
OBJECTIVE Hepatologists and colonoscopists often hesitate to perform a colonoscopic polypectomy in patients with chronic liver disease (CLD), especially those with cirrhosis, because of the risk of postpolypectomy bleeding (PPB). We aimed to investigate the incidence and risk factors of delayed PPB after a colonoscopic polypectomy in patients with CLD. MATERIALS AND METHODS In total, 152 patients with CLD who underwent colonoscopic polypectomy from December 2005 to December 2012 were retrospectively reviewed. RESULTS Cirrhosis was identified in 80 (52.6%) patients. During the study period, 442 polyps were removed and delayed PPB developed in 14 (9.2%) patients. The incidence of delayed PPB was significantly higher in patients with cirrhosis than in those without the disease (13.8% [n = 11] vs. 4.2% [n = 3], p = 0.041). The polyp size (odds ratio, 1.087; 95% confidence interval, 1.009-1.172) and cirrhosis (odds ratio, 8.535; 95% confidence interval, 2.417-30.140) were independent risk factors for delayed PPB. In patients with cirrhosis, the optimal cut-off size to identify high-risk polyps for delayed PPB was 10 mm (area under the receiver operating characteristics curve, 0.737; sensitivity, 52%; specificity, 88%). CONCLUSION Caution is needed when colonoscopic polypectomy is planned in patients with CLD who have larger polyps and cirrhosis.

Ann Gastroenterol 2016; 29:502-508. [PMID: 27708518 PMCID: PMC5049559 DOI: 10.20524/aog.2016.0075] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/29/2016] [Accepted: 07/01/2016] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Bleeding after polypectomy is a common issue associated with colonoscopy. To help prevent post-polypectomy bleeding, many endoscopists place clips at the site. However, this practice remains controversial. Therefore, we performed a meta-analysis of the efficacy of clip placement in the prevention of post-polypectomy bleeding. METHODS Multiple databases, including Embase, Scopus, MEDLINE/PubMed, CINAHL, Cochrane databases, and recent abstracts from major American meetings were searched in April 2016. Using the DerSimonian and Laird (random effects) model with odds ratio (OR), a meta-analysis was performed of post-polypectomy bleeding with prophylactic clip versus no prophylactic clip. RESULTS Five hundred and thirty potential articles and abstracts were discovered. Thirty-five articles were reviewed, with 12 studies satisfying the inclusion criteria. No statistically significant difference in prophylactic clipping versus no prophylactic clipping for post-polypectomy bleeding in all polyps was found when all studies (OR 1.49; 95% CI: 0.56-4.00; P=0.42), only peer-reviewed studies where abstracts were excluded (OR 0.84; 95% CI: 0.42-1.69; P=0.63), and only randomized controlled trials (OR 1.24; 95% CI: 0.69-2.24; P=0.47) were analyzed. CONCLUSIONS The use of prophylactic clipping for all polypectomies does not seem to prevent post-polypectomy bleeding and should not be a routine practice. However, for large polyps (>2 cm), prophylactic clipping may or may not be beneficial in preventing post-polypectomy bleeding. Further studies are required to fully evaluate this subgroup.

Abstract
UNLABELLED The risk of endoscopy in patients on antithrombotics depends on the risks of procedural haemorrhage versus thrombosis due to discontinuation of therapy. P2Y12 RECEPTOR ANTAGONISTS CLOPIDOGREL, PRASUGREL, TICAGRELOR: For low-risk endoscopic procedures we recommend continuing P2Y12 receptor antagonists as single or dual antiplatelet therapy (low quality evidence, strong recommendation); For high-risk endoscopic procedures in patients at low thrombotic risk, we recommend discontinuing P2Y12 receptor antagonists five days before the procedure (moderate quality evidence, strong recommendation). In patients on dual antiplatelet therapy, we suggest continuing aspirin (low quality evidence, weak recommendation). For high-risk endoscopic procedures in patients at high thrombotic risk, we recommend continuing aspirin and liaising with a cardiologist about the risk/benefit of discontinuation of P2Y12 receptor antagonists (high quality evidence, strong recommendation). WARFARIN The advice for warfarin is fundamentally unchanged from British Society of Gastroenterology (BSG) 2008 guidance. DIRECT ORAL ANTICOAGULANTS DOAC For low-risk endoscopic procedures we suggest omitting the morning dose of DOAC on the day of the procedure (very low quality evidence, weak recommendation); For high-risk endoscopic procedures, we recommend that the last dose of DOAC be taken ≥48 h before the procedure (very low quality evidence, strong recommendation). For patients on dabigatran with CrCl (or estimated glomerular filtration rate, eGFR) of 30-50 mL/min we recommend that the last dose of DOAC be taken 72 h before the procedure (very low quality evidence, strong recommendation). In any patient with rapidly deteriorating renal function a haematologist should be consulted (low quality evidence, strong recommendation).

Abstract
Colonoscopy is a frequently performed diagnostic and therapeutic test and the primary screening tool in several nationalized bowel cancer screening programs. There has been a considerable focus on maximizing the utility of colonoscopy. This has occurred in four key areas: Optimizing patient selection to reduce unnecessary or low yield colonoscopy has offered cost-benefit improvements in population screening. Improving quality assurance, through the development of widely accepted quality metrics for use in individual practice and the research setting, has offered measurable improvements in colonoscopic yield. Significant improvements have been demonstrated in colonoscopic technique, from the administration of preparation to the techniques employed during withdrawal of the colonoscope. Improved techniques to avoid post-procedural complications have also been developed-further maximizing the utility of colonoscopy. The aim of this review is to summarize the recent evidence-based advances in colonoscopic practice that contribute to the optimal practice of colonoscopy.

Abstract
BACKGROUND AND STUDY AIMS Bleeding after colonoscopic resection of pedunculated polyps cannot be easily predicted. The aims of this study were to evaluate the blood supply in pedunculated polyps and to clarify the optimal position on the polyp stalk for snare placement to prevent post-polypectomy hemorrhage. ] PATIENTS AND METHODS In one institution, 11 pedunculated polyps from 11 patients were studied prospectively. All polyps were resected at the base of the stalk using a snare wire with electrocautery. Histologic axial sections from the apex and base of the stalk were examined with hematoxylin eosin and elastica stains. Elastica stains were used to identify blood vessels. The cross-sectional area of the stalk, total vessel area, maximum diameter of artery/arteriole lumen, number of thick (≥ 0.1 mm) vessels, and number of arteries/arterioles were measured in each section with image processing software. Wilcoxon signed-ranks test was used for comparison. RESULTS The median polyp diameter was 16 mm (range 7 to 24 mm) and median length of the stalk was 11 mm (range 7 to 23 mm). Two invasive cancers (T1) were included. The maximum diameter of the arterial/arteriolar lumen was greater at the base (P = 0.0044), whereas the ratio of the vessel area to the cross-section area was greater at the apex (P = 0.016). The number of thick vessels and arteries/arterioles were equivalent between apex and base. CONCLUSIONS Morphometric study of the blood supply of pedunculated polyps confirmed that the optimal site for the excision of pedunculated polyps is in the middle of the stalk.

Abstract
A precise endoscopic diagnosis is necessary for endoscopic therapy for neoplastic and non-neoplastic lesions, including juvenile polyps (JPs). Therefore, the present study aimed to clarify the characteristic endoscopic findings of JPs. A total of 154 JPs were evaluated by magnifying chromoendoscopy, 20 of which were also assessed by endocytoscopy using an ultra-high magnification endoscope. Endoscopic images were evaluated in terms of gross appearance, color, pit pattern, surface inflammatory changes and vascularity of polyps. Endocytoscopic images were evaluated with regard to the morphology of glandular cavities, nuclei of glandular cells and interstitial features. Reddish surfaces (98.1%), surface erosion (92.2%), open pits (90.3%) and low pit density (90.3%) were observed in the majority of JPs by chromoendoscopy. In addition, dilated ductal openings surrounded by normal glandular cells (100%), greater distances between gland basal layers (100%) and interstitial infiltration by inflammatory cells (100%) were observed in all JPs examined by endocytoscopy. These findings indicate that there is a tetralogy of magnifying chromoendoscopic findings characteristic of JPs: Reddish surfaces, surface erosion, open pits and low pit density. There is also a triad of endocytoscopic findings characteristic of JPs, namely dilated ductal openings surrounded by normal glandular cells, greater distances between gland basal layers, and interstitial infiltration by inflammatory cells. The aforementioned magnifying chromoendoscopic and endocytoscopic characteristics of JPs may be useful factors for diagnosing JPs.

Abstract
BACKGROUND The risk of postpolypectomy bleeding for patients taking aspirin is low, and gastroenterology society guidelines state that aspirin is likely safe to continue; however, many practices recommend aspirin discontinuation. OBJECTIVE To characterize practice patterns of periprocedural aspirin use with colonoscopy in the United States. DESIGN Survey study. SETTING Endoscopy units in the United States. INTERVENTIONS We reviewed colonoscopy preparation instruction sheets available online to characterize recommendations regarding periprocedural aspirin use. The endoscopy units that recommended discontinuation of aspirin before colonoscopy were contacted to determine their reasons for doing so. We also determined which endoscopy units were recognized by the American Society for Gastrointestinal Endoscopy (ASGE) quality recognition program. MAIN OUTCOME MEASUREMENTS Endoscopy unit recommendations regarding aspirin use before colonoscopy. RESULTS We reviewed colonoscopy preparation instructions from 317 endoscopy units, of which 138 (43.5%) recommended continuing aspirin, 103 (32.5%) recommended stopping aspirin, and 76 (24%) requested patients to contact a physician. The most common reasons for recommending aspirin discontinuation were concern about bleeding after polypectomy (62%), perceived minimal downside to stopping aspirin (38%), inertia to changing old policies (20%), and concern about medicolegal implications of postpolypectomy bleeding (15%). There was no significant association between endoscopy unit recommendations about periprocedural aspirin use and ASGE quality certification (P = .17) or type of endoscopy facility (ambulatory surgical center vs hospital affiliated) (P = .55). LIMITATION Non-response bias. CONCLUSION Less than half of the endoscopy units surveyed in the United States routinely continue aspirin before screening colonoscopies despite evidence that benefits outweigh the risks. It is important for gastroenterology and cardiology societies to make a firm statement, educate their members, and give them confidence and support to continue aspirin periprocedurally.

Abstract
BACKGROUND Endoscopic resection of large pedunculated colorectal polyps is technically difficult, especially when the polyps are so large that it is either not possible or too difficult to resect them using a conventional polypectomy snare. AIM To facilitate the removal of pedunculated colorectal polyps, we developed a new technique using a combination of a dual knife and preventive hemostatic procedures. METHODS Nine patients (5 men and 4 women; mean age, 59.8 y; range, 49 to 79 y) with pedunculated polyps >2 cm in diameter were treated with this technique. A dual knife and endoclips or an endoloop were used as needed. RESULTS All lesions, except for 1 polyp, were resected endoscopically. The mean time for complete resection was 8.5 minutes (range, 1.5 to 16 min). The procedure time decreased significantly after the fifth case (168 vs. 746 s, P=0.0009). No hemorrhage, perforation, or other complications occurred during follow-up among the endoscopically resected cases. CONCLUSIONS Combined use of a dual knife and prophylactic hemostatic procedures is a feasible alternative technique for removing large pedunculated colorectal polyps when conventional snare resection is impossible or difficult.

Abstract
BACKGROUND Submucosal injection for endoscopic mucosal resection (EMR) may effect performing the prophylactic argon plasma coagulation (APC) of non-bleeding visible vessels on ulcer crater. AIMS The purpose of this study was to evaluate the clinical features of visible vessels in iatrogenic ulcers over time after prophylactic APC in colonic EMR. PATIENTS AND METHODS This study was designed as a prospective study. Between August and November 2013, a total of 40 patients who were admitted underwent prophylactic APC for non-bleeding visible vessels after colonic EMR. After confirming whether visible vessels were completely coagulated or not, the number of visible vessels in ulcers was counted over a specific time period, e.g. 1, 3, 5, or 7 min. RESULTS The mean number of visible vessels was significantly higher at 5 min (0.85 ± 1.14) after EMR with prophylactic APC compared to 1 and 3 min (1 min: 0.28 ± 0.60, P < 0.001; 3 min: 0.65 ± 0.87, P = 0.02) and there was no significant difference between 5 and 7 min (P = 0.31). Multivariate analysis showed that the size of the iatrogenic ulcer after EMR was associated with the occurrence of visible vessels (ulcer size >1 vs. ≤0.5 cm: OR 27.32, 95% CI 2.86-infinity). CONCLUSIONS A 5-min observation of the ulcer may be advantageous for the assessment of visible vessels after performing colonic EMR with prophylactic APC, and large (>1 cm) iatrogenic ulcers were associated with the occurrence of visible vessels after colonic EMR.

Abstract
BACKGROUND AND AIM Post-polypectomy bleeding (PPB) is the most common adverse event of colonoscopic polypectomy, especially in cases with large pedunculated polyps. To minimize the risk of PPB, several endoscopic preventive methods have been performed. The aim of this prospective, randomized study was to compare the rates of PPB following single (clipping alone) and combined (clipping plus epinephrine-saline injection) methods in prevention of PPB in large pedunculated polyps. METHODS Adult patients with pedunculated colorectal polyps with heads ≥ 10 mm were prospectively enrolled from March 2011 to January 2013. Patients were randomized to receive treatment of either clips alone (group A) or clips plus injection of epinephrine-saline (group B) prior to a conventional polypectomy. PPB rate in both groups were compared. RESULTS A total of 148 patients with 173 pedunculated colorectal polyps were enrolled. Groups A and B each had 74 patients, with 83 and 90 polyps, respectively. The mean head diameters were 17.2 ± 6.6 and 17.5 ± 6.7 mm in groups A and B, respectively (P = 0.748). Immediate PPB (IPPB) occurred in 10 cases (12.0%) from group A and 13 cases (14.4%) from group B (P = 0.64). There were no cases of delayed PPB or perforation. Multivariate analysis showed that inadequate bowel preparation and large head diameter of polyp were independent risk factors for IPPB. CONCLUSIONS The rate of IPPB is relatively high in cases with large pedunculated polyps, but these polyps can be successfully resected by snare polypectomy following use of the single prophylactic clipping method.

Abstract
Background/Aims Among the many complications that can occur following therapeutic endoscopy, bleeding is the most serious, which occurs in 1.0-6.1% of all colonoscopic polypectomies. The aim of this study was to identify risk factors of delayed post-polypectomy bleeding (PPB). Methods We retrospectively reviewed the data of patients who underwent colonoscopic polypectomy between January 2003 and December 2012. We compared patients who experienced delayed PPB with those who did not. The control-to-patient ratio was 3:1. The clinical data analyzed included polyp size, number, location, and shape, patient' body mass index (BMI), preventive hemostasis, and endoscopist experience. Results Of 1,745 patients undergoing colonoscopic polypectomy, 21 (1.2%) experienced significant delayed PPB. We selected 63 age- and sex-matched controls. Multivariate logistic regression analysis showed that polyps >10 mm (odds ratio [OR], 2.605; 95% confidence interval [CI], 1.035-4.528; P=0.049), a pedunculated polyp (OR, 3.517; 95% CI, 1.428-7.176; P=0.045), a polyp located in the right hemicolon (OR, 3.10; 95% CI, 1.291-5.761; P=0.013), and a high BMI (OR, 3.681; 95% CI, 1.876-8.613; P=0.013) were significantly associated with delayed PPB. Conclusions Although delayed PPB is a rare event, more caution is needed during colonoscopic polypectomies performed in patients with high BMI or large polyps, pedunculated polyps, or polyps located in the right hemicolon.
