G-EYE Colonoscopy Is Superior to Standard Colonoscopy for Increasing Adenoma/Polyp Detection Rate

Abstract Background Colorectal cancer (CRC) is one of the most common cancers worldwide. Most CRCs develop from malignant potential polyps, especially adenomas, SSPs and SSLs. Screening is associated with a reduction in CRC incidence through the detection and removal of precancerous polyps and with reduction in CRC related death through reduction of the incidence and early detection of CRC. Colonoscopy is the most widely used screening tool. Unfortunately during colonoscopy examinations, a substantial number of polyps are still being missed. These missed polyps though to be at least 50% of interval CRCs. Objective comparison between G-EYE colonoscopy and standard colonoscopy (SC) for increasing adenoma/polyp detection rate. Patients and Methods prospective randomized study was conducted on 80 Patients as one group, selection done at Hepatology and Gastroenterology department in Theodor Bilharz Research Institute and Outpatient clinic of Gastroenterology unit at Ain Shams University Hospitals. From: June 2021 to November 2021, after ethical committee approval. Results prospective randomized study demonstrated that the polyp detection rate (PDR) was an increased rate by G-EYE colonoscopy, this difference was statistically significant (P ≤ 0.05) as the total number of patients having polyps detected by G-EYE was 28 (40.60%) and the total number of polyps was 43 polyps while by SC was 15 (21.70%) and the total number of polyps was 19 polyps. There is an advantage for G-EYE over SC in relation to the size of the detected polyps as this study compared the detected polyp size as diminutive (<5 mm), small (6-9 mm) and large polyps (>10 mm) by G-EYE versus SC. For the diminutive polyps, the difference was statistically significant (P ≤ 0.05) favoring the G-EYE, and for small polyps the G-EYE was superior to SC by 3 polyps, while for large polyps there was no difference. G-EYE increased the ADR in comparison with SC [22 (100%) vs 9 (13%) ] respectively as G-EYE colonoscopy detected an additional 15 adenomatous polyps in 13 patients missed from SC colonoscopy. The difference was statistically significant. Fortunately there were very few complications, abdominal pain reported in 3 cases after the end of procedures. Conclusion The study demonstrated that G-EYE is superior to SC in increasing adenoma and polyp detection rate as being more rapid and more precise for detection of diminutive and small adenomatous polyps. However G-EYE could not be done in certain conditions such as diverticulosis, masses, ulcerations or colonic strictures for fear of perforation or incomplete intubation, in this study those patients were excluded from the start as the aim of the study was polyp detection rate difference by balloon assisted colonoscopy (G-EYE) in comparison to the standard colonoscopy (SC).

Systematic review and meta-analysis of cold snare polypectomy and hot snare polypectomy for colorectal polyps.

Cold snare polypectomy (CSP) has become increasingly utilized to resect colorectal polyps, given its efficacy and safety. This study aims to compare CSP and hot snare polypectomy (HSP) for resecting small (<10mm) and large (10-20mm) colorectal lesions. Relevant publications were obtained from Cochrane Library, Embase, Google Scholar, PubMed, and Web of Science databases. The publication search was limited by English-language and human studies. Pooled mean difference and odds ratios (ORs) were calculated for outcomes of interest. Twenty-three studies were included in this meta-analysis. Pooled OR of delayed post-polypectomy bleeding (DPPB) in the CSP group versus the HSP group was 0.29 (P=0.0001, I2 =29%). Subgroup analysis according to lesion size showed a significant reduction in the DPPB rate in lesion sizes 10-20mm (pooled OR 0.08, P=0.003, I2 =0%) and <10mm (pooled OR 0.35, P=0.001, I2 =27%). Pooled OR of major bleeding in the CSP group was 0.23 (P=0.0004, I2 =0%). Subgroup analysis by lesion size revealed a significant decrease in the rate of major bleeding in the CSP group for both lesion sizes 10-20mm (pooled OR 0.11, P=0.04) and <10mm (pooled OR 0.26, P=0.003). Complete resection, en bloc resection, and recurrence rate were comparable in the two groups. Cold snare polypectomy was associated with a lower rate of DPPB and lower risk of major bleeding compared with HSP in both small and large polyps. CSP should be considered as the polypectomy technique of choice for colorectal polyps.

Endoscopic Management of Large Non-Pedunculated Colorectal Polyps.

Large non-pedunculated colorectal polyps ≥20 mm (LNPCPs) comprise approximately 1% of all colorectal polyps. LNPCPs more commonly contain high-grade dysplasia, covert and overt cancer. These lesions can be resected using several means, including conventional endoscopic mucosal resection (EMR), cold-snare EMR (C-EMR) and endoscopic submucosal dissection (ESD). This review aimed to provide a comprehensive, critical and objective analysis of ER techniques. Evidence-based, selective resection algorithms should be used when choosing the most appropriate technique to ensure the safe and effective removal of LNPCPs. Due to its enhanced safety and comparable efficacy, there has been a paradigm shift towards cold-snare polypectomy (CSP) for the removal of small polyps (<10 mm). This technique is now being applied to the management of LNPCPs; however, further research is required to define the optimal LNPCP subtypes to target and the viable upper size limit. Adjuvant techniques, such as thermal ablation of the resection margin, significantly reduce recurrence risk. Bleeding risk can be mitigated using through-the-scope clips to close defects in the right colon. Endoscopic surveillance is important to detect recurrence and synchronous lesions. Recurrence can be readily managed using an endoscopic approach.

Schistosomal (bilharzial) polyps: Travel through the colon and beyond.

Schistosomiasis (bilharziasis) is a major neglected tropical disease. It is endemic in many tropical and subtropical communities. Schistosomal polyps (S. polyps) are not uncommon presentation of this infection. Although the colon is the most commonly affected organ, many other organs are affected. S. polyps are associated with a variable range of morbidity independent of the Schistosomal infection. S. polyps are frequently described in endemic areas and increasingly reported in non-endemic areas mainly among immigrants and visitors to the endemic areas. This review aimed to increase awareness of practitioners, especially gastroenterologists, for this peculiar type of polyps caused by this neglected infection hence improving patient outcomes. Web-based search of different databases was conducted for the literature focusing the development of S. polyps in the colon and other organs with analysis of the clinical manifestations, diagnosis and treatment. The following key words were used in the search, "Schistosomiasis" OR "Bilharziasis" AND "Polyps" OR "Polyp" AND "Colon" OR "Small intestine" OR " Duodenum" OR " Stomach" OR "Esophagus" OR " Gallbladder" OR" Pharynx" OR "Larynx" OR "Trachea" OR "Urinary bladder" OR " Ureter" OR "Renal Pelvis" OR "Urethra". All publication types including case reports, case series, original research, and review articles were retrieved and analyzed. S. polyps are not infrequent presentation of acute or chronic Schistosomal infection. S. polyps are described in many organs including the bowel, genitourinary tract, skin, gallbladder and the larynx. Presentation of S. polyps is variable and depends on the site, number as well as the polyp size. The relationship of S. polyps to malignant transformation is a matter of discussion. Presence of S. polyps is sometimes the only manifestation of Schistosomiasis. Small polyps can be treated medically with praziquantel, while large accessible polyps are amendable for endoscopic excision through different polyp resection techniques. However, huge, complicated, non-accessible and suspicious polyps are indicated for surgical management or advanced endoscopic resection when appropriate. Clinicians and endoscopists should be aware about these facts when treating patients living in, immigrated from or visiting endemic areas.

Weighing the Trade-Offs of a Revised Approach to Small Gallbladder Polyps

Weighing the Trade-Offs of a Revised Approach to Small Gallbladder Polyps

Ultrasound Surveillance of Small, Incidentally Detected Gallbladder Polyps: Projected Benefits by Sex, Age, and Comorbidity Level

ObjectiveIncidentally detected gallbladder polyps are commonly encountered when performing upper abdominal ultrasound. Our purpose was to estimate the life expectancy (LE) benefit of ultrasound-based gallbladder surveillance in patients with small (6-7 to <10 mm), incidentally detected gallbladder polyps, accounting for patient sex, age, and comorbidity level. MethodsWe developed a decision-analytic Markov model to evaluate hypothetical cohorts of women and men with small gallbladder polyps, with varying age (66-80 years) and comorbidity level (none, mild, moderate, severe). Drawing from current evidence, in the base case, we assumed no increased risk of gallbladder cancer in patients with small gallbladder polyps. To estimate maximal possible LE gains from surveillance, we assumed perfect cancer control consequent to 5 years of surveillance. We varied key assumptions including cancer risk and test performance characteristics in sensitivity analysis. ResultsProjected LE gains from surveillance were <3 days across most cohorts and scenarios evaluated. For 66- and 80-year-olds with no comorbidities, LE gains were 1.46 and 1.45 days, respectively, for women, and 0.67 and 0.75 days for men. With 10 years of surveillance, LE gains increased to 2.94 days for 66-year-old women with no comorbidities (men: 1.35 days). If we assumed a 10% increase in gallbladder cancer risk among individuals with polyps, LE gains increased slightly to 1.60 days for 66-year-old women with no comorbidities (men: 0.74 days). Results were sensitive to test performance and surgical mortality. DiscussionEven under unrealistic, optimistic assumptions of cancer control, ultrasound surveillance of incidentally detected small gallbladder polyps provided limited benefit.

Economic impact of implementing optical diagnosis with a "resect and discard" strategy within the English Bowel Cancer Screening Programme: Findings from the DISCARD3 study.

Advances in endoscopic technology, such as narrow band imaging and high definition colonoscopes, offer the potential for optical diagnosis (OD) with a "resect and discard" (RD) strategy for diminutive (≤5mm) and small (6-9mm) colorectal polyps. This could help alleviate the huge cost and time burden required for histopathology. The aim of this study is to conduct an economic analysis of a RD strategy within the English Bowel Cancer Screening Programme (BCSP). A decision tree was designed to compare a RD strategy with standard histopathology for patients included in the DISCARD3 study and was extrapolated to a national BCSP patient cohort. Of the 525 patients in the DISCARD3 study, 354 were assessed for surveillance intervals (after excluding cases with colorectal cancer and at least one polyp >10 mm). 269/354 cases had polyps of which, 182 had only diminutive polyps, 77 had both small and diminutive polyps, and 10 had only small polyps. Surveillance interval concordance was 97.9% in patients with at least 1 diminutive polyp and 98.7% in patients with at least 1 diminutive or small polyp. In DISCARD3, a RD approach would reduce overall direct healthcare costs by £35,468.8 (-72.3%) for patients with diminutive polyps or by £42,666.2 (-75.0%) for patients with diminutive or small polyps. When extrapolated to the entire English BCSP, the annual savings are almost £2.4m for patients with diminutive polyps or £3.4m for patients with diminutive or small polyps, after adjusting for the costs of an OD quality assurance process (QAP). OD with a RD strategy for diminutive and small polyps during BCSP colonoscopy would offer substantial cost savings without adversly affecting surveillance interval concordance.

Association of Antibody Responses to Fusobacterium nucleatum and Streptococcus gallolyticus Proteins with Colorectal Adenoma and Colorectal Cancer

BackgroundStreptococcus gallolyticus subspecies gallolyticus (SGG) and Fusobacterium (F.) nucleatum have been implicated in colorectal carcinogenesis. Here, the association of immune responses to bacterial exposure with advancing stages of colorectal neoplasia was assessed by multiplex serology.MethodsImmunoglobulin (Ig) A and G antibody responses to eleven proteins each of F. nucleatum and SGG were measured in plasma of controls (n = 100) and patients with colorectal cancer (CRC, n = 25), advanced adenoma (n = 82), or small polyps (n = 85). Multivariable logistic regression was used to evaluate the association of bacterial sero-positivity with colorectal neoplasia. In a cohort subset with matched data (n = 45), F. nucleatum sero-positivity was correlated with bacterial abundance in both neoplastic and matched normal tissue.ResultsIgG sero-positivity to Fn1426 of F. nucleatum was associated with an increased CRC risk (OR = 4.84; 95% CI 1.46–16.0), while IgA sero-positivity to any SGG protein or specifically Gallo0272 and Gallo1675 alone was associated with increased advanced adenoma occurrence (OR = 2.02, 95% CI 1.10–3.71; OR = 2.67, 95% CI 1.10–6.46; and OR = 6.17, 95% CI 1.61–23.5, respectively). Only F. nucleatum abundance in the normal mucosa positively correlated with the IgA response to the Fn1426 antigen (Correlation coefficient (r) = 0.38, p < 0.01).ConclusionAntibody responses to SGG and F. nucleatum were associated with occurrence of colorectal adenomas and CRC, respectively. Further studies are needed to clarify the role these microbes or the immune response to their antigens may have in colorectal carcinogenesis stages.Graphical

Efficacy and Safety of Cold Snare Polypectomy of Colorectal Polyps 10–15 mm with a Hybrid Snare: A Prospective Observational Pilot Study

Introduction: Cold snare polypectomy (CSP) is a safe and effective procedure for small colorectal polyps ≤9 mm. There are only limited data regarding CSP of larger neoplastic lesions. This study evaluated the efficacy and safety of CSP for polyps between 10 and 15 mm in size. Methods: In this prospective single-arm observational pilot study, patients with a least one polyp 10–15 mm were included. These polyps were preferably removed by CSP using a dedicated hybrid snare. The primary outcome was the histological complete resection rate (CRR) determined by pathologically negative margins of the specimen and no neoplastic tissue obtained from biopsies of the resection site margin. Secondary outcomes were en bloc resection rate, failure of CSP, and incidence of adverse events. Results: A total of 61 neoplastic polyps were removed from 39 patients. Overall CRR was 80.3% (49/61). CSP was feasible in 78.7% (48/61) of polyps and the CRR in this group was 85.4% (41/48). When CSP failed (13/61; 21.3%), lesions were successfully resected by immediate HSP using the same snare with a CRR of 61.5% (8/13) in this group. One patient presented delayed hemorrhage after HSP of a polyp but successful hemostasis was achieved with two hemoclips. No other adverse events occurred. No recurrence was seen on follow-up colonoscopy in cases with incomplete resected polyps. Conclusion: CSP seems to be efficient and safe in removing colorectal polyps up to 15 mm. A hybrid snare seems to be particularly advantageous for these polyps as it allows immediate conversion to HSP if CSP might fail in larger polyps. This trial is registered at ClinicalTrials.gov (NCT04464837).

Varied Trainee Competence in Cold Snare Polypectomy - Results of the COMPLETE Randomized Controlled Trial.

Cold snare polypectomy (CSP) is strongly recommended as the optimal technique for the complete removal of small polyps. Though significant variability in polypectomy technique and quality has been established, the learning curve and impact of targeted training on CSP are unknown. Video feedback has shown promise as an effective pedagogy to improve performance among surgical trainees. We aimed to compare CSP performance between trainees who received video-based feedback to conventional apprenticed-based concurrent feedback. We hypothesized that video feedback would accelerate competence. We conducted a single-blinded, randomized controlled trial on competence for CSP of polyps <1cm, comparing video to conventional feedback. We randomly assigned de-identified consecutively recorded CSP videos to blinded raters to assess using the CSP Assessment Tool (CSPAT). We shared cumulative sum (CUSUM) learning curves every 25 CSPs with each trainee. The video feedback trainees also received biweekly individualized terminal feedback. Control trainees received conventional feedback during colonoscopy. The primary outcome was CSP competence. We also assessed competence across domains and change over polypectomy volume. We enrolled and randomized 22 trainees; 12 to video and 10 to conventional feedback, and evaluated 2339 CSPs. The learning curve was long; two trainees (16.7%) in the video feedback achieved competence, after a mean of 135 polyps, and no one in the control (p=0.481) achieved competence. Overall and in all steps of CSP, a higher percentage of the video feedback group met competence, increasing 3% every 20 CSPs (P=0.0004). Video feedback aided trainees to competence in CSP. However, the learning curve was long. Our findings strongly suggest that current training methods are not sufficient to support trainees to competency by the completion of their fellowship programs. The impact of new training methods, such as simulation-based mastery learning, should be assessed to determine if such methods can result in achievement of competence at a faster rate; ClinicalTrials.gov: NCT03115008.

Rigid normograde rhinoscopy-assisted traction-avulsion removal of small middle ear polyps from the auditory tube in five cats.

This study aims to describe a novel minimally invasive technique for the removal of small middle ear polyps from the auditory tube openings in cats. Five cats with clinical signs of otitis externa and/or otitis media, and/or upper respiratory tract inflammation were included. All cats underwent pharyngolaryngoscopy under anaesthesia, CT scan of the head, neck and thoracic cavity, video-otoscopic examination, retrograde nasopharyngoscopy and normograde rhinoscopy. The five cats described in this study were all found to have significant respiratory tract inflammation (rhinitis, sinusitis, nasopharyngitis, otitis media) with small polypous protrusions from the auditory tube openings. A normograde rhinoscopy-assisted traction-avulsion (RATA) removal of these small polyps was performed in all cases without complications. The rostral nasopharynx was visualised by a unilaterally normograde advanced rigid endoscope passing the choana, and polyps were removed using a grasping forceps introduced in the contralateral nostril. Telephone follow-up revealed clear improvement in all cases. One of the cases was re-evaluated with a CT scan and endoscopy 4 weeks after treatment. The CT scan showed a significant improvement with no abnormalities in both external ear canals and air opacity in both tympanic bullae. Video-endoscopic examination revealed intact tympanic membranes with mild chronic abnormalities and patent auditory tube openings upon normograde rhinoscopy. Rigid normograde RATA is a novel, minimally invasive and effective technique for the removal of small middle ear polyps from auditory tube openings in cats with otitis media.

Utility of narrow-band imaging with or without dual focus magnification in neoplastic prediction of small colorectal polyps: a Vietnamese experience.

Accurate neoplastic prediction can significantly decrease costs associated with pathology and unnecessary colorectal polypectomies. Narrow band imaging (NBI) and dual-focus (DF) mode are promising emerging optical technologies for recognizing neoplastic features of colorectal polyps digitally. This study aimed to clarify the clinical usefulness of NBI with and without DF assistance in the neoplastic prediction of small colorectal polyps (<10 mm). This cross-sectional study included 530 small colorectal polyps from 343 consecutive patients who underwent colonoscopy at the University Medical Center from September 2020 to May 2021. Each polyp was endoscopically diagnosed in three successive steps using white-light endoscopy (WLE), NBI, and NBI-DF and retrieved for histopathological assessment. The diagnostic accuracy of each modality was evaluated with reference to histopathology. There were 295 neoplastic polyps and 235 non-neoplastic polyps. The overall accuracies of WLE, WLE+NBI, and WLE+NBI+NBI-DF in the neoplastic prediction of colorectal polyps were 70.8%, 87.4%, and 90.8%, respectively (p<0.001). The accuracy of WLE+NBI+NBI-DF was significantly higher than that of WLE+NBI in the polyp size ≤5 mm subgroup (87.3% vs. 90.1%, p<0.001). NBI improved the real-time neoplastic prediction of small colorectal polyps. The DF mode was especially useful in polyps ≤5 mm in size.

Description and life cycle of a new species of the genus Arachnanthus (Cnidaria: Anthozoa: Ceriantharia) from the Southwestern Atlantic Ocean.

Ceriantharia is a subclass of the phylum Cnidaria, which comprises tube-dwelling marine invertebrates. This subclass is composed of three families, including Arachnactidae, with two known genera. Currently, the genus Arachnanthus has five valid species recorded from Australia, the Mediterranean Sea and both the Southern and Northern Pacific Ocean. However, at the moment, there is no record of organisms of this family from the South Atlantic Ocean. Besides that, the life cycle of any species of the genus Arachnanthus is known. The present study describes a new species of the genus Arachnanthus and its life cycle, based on specimens from Uruguay and South of Brazil. Larvae were collected by plankton net in Rio Grande-Brazil and the development and external morphology of these specimens were observed in the laboratory during two years, and subsequently described. Additionally, nine adult ceriantharians correspondent to the larvae from Rio Grande were collected in Uruguay and their external and internal anatomies, and cnidome were described. Arachnanthus errans sp. nov. exhibited a free-swimming, short-lived cerinula larvae that spent short-time on the plankton. The larva developed into small and translucent polyps with a short actinopharynx, one pair of mesenteries attached to a siphonoglyph, and a medium first pair of metamesenteries. Further, the adult polyp displayed an unprecedented locomotion behavior in Ceriantharia that is first reported here, it can crawl under and in between the sediment.

The efficacy and safety of cold snare versus hot snare polypectomy for endoscopic removal of small colorectal polyps: a systematic review and meta-analysis of randomized controlled trials.

The optimal technique for removing small colorectal polyps ranging from 5 to 10mm in size remains uncertain. In order to compare the efficacy and adverse events between cold snare polypectomy (CSP) and hot snare polypectomy (HSP) for removing small polyps, we conducted a systematic review and meta-analysis of available randomized controlled trials. We conducted a comprehensive search of MEDLINE, EMBASE, and the Cochrane Library databases from 1998 to May 2023 to identify randomized controlled trials that evaluated the efficacy and safety of cold snare polypectomy (CSP) and hot snare polypectomy (HSP) for resecting small colorectal polyps. The primary outcome measure was the incomplete resection rate (IRR). Seven studies that met our study criteria, with a total of 3178 included polyps, were included in our analysis. The incomplete resection rate (IRR) was found to be significantly higher in the CSP group compared to the HSP group (risk ratio [RR] 1.57 [1.17-2.11], P = 0.003). Although the CSP group had a higher local recurrence rate than the HSP group, the difference was not statistically significant (RR: 3.98 [0.66-23.84], P = 0.13). The polyp retrieval rates were not significantly different between the two groups (RR: 1.00 [0.99-1], P = 0.22). Perforation was not reported or mentioned in any of the seven studies. The overall immediate bleeding rate was significantly higher in the CSP group than the HSP group (RR: 2.26 [1.63-3.14], P < 0.001), but immediate postpolypectomy bleeding requiring additional intervention was similar between the groups (RR: 1.08 [0.54-2.17], P = 0.82). The delayed bleeding rate (RR: 0.83 [0.45-1.55], P = 0.56) and specific polypectomy time (RR: -0.46 [-1.05-0.12], P = 0.12) were also similar between the groups. The meta-analysis shows a significantly higher IRR for CSP compared with HSP when removing small polyps.

MR enterography in small bowel diseases, adding multipoint Dixon sequence, is it worth?

BackgroundMR enterography (MRE) has been increased in the last decade as a modality of choice in diagnosis and evaluation of small bowel diseases in both children and adults. Lacking ionizing radiation, non-invasiveness, excellent soft tissue resolution, adequate luminal distension of small bowel loops are the advantages of this technique. Acquisition of images was used to be: T2WI, steady-state free precession, and T1WI, fat-suppressed gadolinium contrast-enhanced sequences. Multipoint Dixon sequence was added recently to the routine MR enterography protocol. The current study aimed to evaluate the added value of multipoint Dixon sequence as a valuable modification of MR enterography protocol for better assessment of small bowel lesions as activity of Crohn’s disease, small bowel polyps, fibrotic strictures, with modification of MRE protocol in the future with less time consumption and better radiological evaluation.MethodsThe current research was a prospective cross-sectional study. Data were collected prospectively after getting ethical approval from the ethical committee of the faculty of medicine, in our university.Study populationThe sample size was 69 adult patients with suspected small bowel lesions, within the period from January 2022 to 30th December 2022. Written informed consent was obtained from all studied cases before the study, who were enrolled in this study. This number was calculated by using MedCalc 19 program by setting alpha error significance of 0.05%, 95% confidence level, and 80% power sample.ResultsThis study enrolled 69 patients with recurrent abdominal pain and/or bleeding in stool. The patients’ age ranged from 18 to 50 years, with a mean of 32.6 ± 8.8. There is slightly higher female prevalence. The most common positive imaging findings in the studied patients were mucosal thickening in terms of submucosal fat deposition (36.23% of the MRE examination and 39.13% of the MRE with added Dixon sequence). Adding Dixon sequence yielded significantly higher AUC (97.2% vs. 90.5%, p = 0.047), higher sensitivity (100% vs. 92.16%), specificity (94.4% vs. 88.89%), accuracy (98.55% vs. 91.3%), positive predictive value (98.08% vs. 95.92%), and negative predictive value (100% vs. 80%).ConclusionsMRE is an excellent imaging modality in the assessment of small bowel diseases without the use of ionizing radiation. Developing MR-based sequences as multi-point Dixon sequence have the potential to improve the ability of MRE to image the subtle changes as Crohn’s accompanying early inflammatory changes and fibrosis, as well as small intestinal polyps. Familiarity with MR enterography is essential for radiologists and gastroenterologists who participate in the clinical management of small intestinal diseases.

Cold Snare Polypectomy for Small Colorectal Polyps—Quick and Safe

Overall, these data suggest that CSP is safer than HSP for the removal of small, 4-10-mm polyps. CSP also obviates the need to prepare an electro-surgical generator or lifting solution for HSP, resulting in faster polypectomy and procedure times. Concerns about incomplete histologic resection appear to be unfounded, as there was no difference in successful tissue retrieval, en bloc resection, or complete histologic resection between groups. Limitations include the lack of endoscopic blinding and follow-up colonoscopy to confirm the bleeding site, particularly in patients who underwent concurrent large polyp resection. Nevertheless, these findings support the enthusiasm for CSP which, based on an improved safety and efficiency profile, appears poised to replace HSP for the routine resection of small colo-rectal polyps.
