Unsedated colonoscopy utilizing virtual reality distraction: a pilot-controlled study. Surg Endosc 2024:10.1007/s00464-024-10999-1. [PMID: 39014179 DOI: 10.1007/s00464-024-10999-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Accepted: 06/08/2024] [Indexed: 07/18/2024]
Abstract
BACKGROUND Sedation increases colonoscopy risks and prolongs recovery time. We examined whether virtual reality (VR) can substitute for sedation. The primary outcome was the overall satisfaction of patients who underwent colonoscopy with VR headset compared with patients who underwent standard sedation. Pain during the procedure, polyp detection rate (PDR), colonoscopy duration, post-colonoscopy adverse events, post-colonoscopy recovery, time-to-return to daily functions, and turnaround time at the endoscopy unit were secondary outcomes. METHODS The study was approved by Sheba Medical Center's ethics committee IRB number 21-8177-SMC. Sixty patients were sequentially enrolled in a 1:1 ratio to either standard sedated colonoscopy or VR-unsedated procedure, and all patients signed a written informed consent. 28/30 patients successfully completed the colonoscopy using VR headset. Overall satisfaction score was comparable between the groups. RESULTS There was no difference between VR and controls in colonoscopy duration, or PDR. VR patients had numerically lower rate of post-colonoscopy adverse events than controls. The proportion of VR patients who reported resuming daily activities on the day of the procedure was significantly higher than in the control group. The VR group patients spent significantly less time in the hospital compared to the control group. CONCLUSIONS VR technology can provide adequate substitution for sedation for most patients undergoing colonoscopy and offers comparable patient satisfaction and faster return to daily activities.

Abstract
Transmesenteric internal hernia is an uncommon cause of small bowel obstruction that occurs when small bowel loops protrude through a mesenteric defect into the abdominal cavity. Herein, we present an unexpected case of colonoscopy-induced transmesenteric internal hernia. An 81-year-old male patient presenting with intermittent hematochezia and constipation had undergone a laparoscopic left nephrectomy for ureteral cancer. A colonoscopy was performed to identify the etiology of his symptoms. He complained of severe abdominal pain 2 h after the examination despite uneventful endoscopic procedures, including cold snare polypectomy. Contrast-enhanced computed tomography revealed a strangulated small bowel obstruction with a closed-loop formation outside the descending colon. The small bowel loop was incarcerated into the left retroperitoneal space. Emergency laparotomy detected small bowel loops that prolapsed into the nephrectomy pedicle via a descending mesenteric defect, developed during the laparoscopic left nephrectomy. The incarcerated small bowel was detached from the hernia and returned to its normal position, and the mesenteric defect was closed. He demonstrated an uneventful postoperative course, with no internal hernia recurrence after discharge. This case indicates the risk of transmesenteric internal hernia through inadvertently created mesenteric defects should be borne in mind, especially when performing colonoscopies in patients who underwent laparoscopic nephrectomies.

Xiang SH, Xu GQ. Colo-colonic intussusception as a rare complication of colonoscopy with polypectomy: Two case reports. World J Gastrointest Surg 2024; 16:1939-1947. [PMID: 38983333 PMCID: PMC11229999 DOI: 10.4240/wjgs.v16.i6.1939] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2024] [Revised: 04/28/2024] [Accepted: 05/23/2024] [Indexed: 06/27/2024] Open
Abstract
BACKGROUND Colonoscopy is the most frequently used diagnostic and therapeutic tool for the treatment of colorectal diseases. Although the complication rate is low, it can be potentially serious. Intussusception is a rare and severe complication often associated with polypectomy. Only a handful of post-colonoscopy intussusception cases have been reported, making this study a valuable addition to the medical literature. CASE SUMMARY Case 1: A 61-year-old man underwent colonoscopy with polypectomy for chronic abdominal pain. The patient experienced abdominal pain 11 hours later but was still discharged after pain management. He was readmitted due to recurring pain. Computed tomography (CT) showed colo-colonic intussusception. Initial conservative management and attempts at endoscopic reduction failed; therefore, laparoscopic right hemicolectomy was performed. Histopathological examination revealed tubular adenomas in the polyps and inflammation in the resected specimens. Case 2: A 59-year-old woman underwent colonoscopy with polypectomy for a polyp in the transverse colon. She experienced upper abdominal pain, fever, nausea, and vomiting 9 hours after the procedure. Emergency CT and blood tests revealed a colo-colonic intussusception near the hepatic flexure and an elevated white blood cell count. Initial attempts at endoscopic reduction failed and conservative treatment showed no improvement. She underwent successful laparoscopic reduction and recovered uneventfully. Histopathological examination of the resected polyp revealed hyperplasia. CONCLUSION Post-colonoscopy intussusception in adults is rare, and polypectomy may contribute to its occurrence. Early diagnosis is crucial, with prompt CT examination serving as key. After excluding malignancies, conservative management and reduction of intussusception should be considered before surgical bowel resection.

Abstract
BACKGROUND Effective bowel cleansing is essential for a successful colonoscopy. Laxatives, such as polyethylene glycol, are commonly used for bowel preparation. Vomiting is a frequent complication during bowel preparation, and forceful vomiting can potentially lead to esophageal perforation, as reported in several previous cases. However, pharyngeal perforation during bowel preparation has not been previously documented. Here, we present a case of pharyngeal perforation induced by forceful vomiting during bowel preparation. CASE SUMMARY A 38-year-old man with a history of hypertension, dyslipidemia, diabetes mellitus, and end-stage renal disease on hemodialysis was admitted for evaluation of recurrent abdominal pain. The patient complained of sudden pain in the neck, throat, and anterior chest following forceful vomiting during bowel preparation. Physical examination revealed crepitus under the skin of the neck and anterior chest on palpation, and upper gastrointestinal endoscopy revealed pharyngeal perforation. The perforation site was located above the upper esophageal sphincter, which distinguished it from Boerhaave's syndrome. Conservative medical management was chosen after consultation with a thoracic surgeon and an otolaryngologist, considering the patient's mild symptoms, stable vital signs, and the small size of the lesion; the perforation resolved without endoscopic or surgical intervention. The patient was discharged from hospital two weeks after the perforation. CONCLUSION Despite its rarity, pharyngeal perforation should be considered a potential complication of bowel preparation for colonoscopy.

Abstract
INTRODUCTION Colonoscopy is regarded as a safe diagnostic and therapeutic procedure, nevertheless, some patients may still encounter post-colonoscopy gastrointestinal symptoms. This study aimed to evaluate the utilization of probiotics before and after colonoscopy to relieve those symptoms. METHODOLOGY This study was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) 2020 guidelines. Included studies were all interventional studies examining the effects of probiotics use before and after colonoscopy. Articles were retrieved from MEDLINE, EBSCO-Host, Cochrane, ProQuest, and Google Scholar electronic databases, utilized specific keywords ( " Probiotic " OR " Probiotics ") AND (" Colonoscopy " OR " Colonoscopies "). The Cochrane Risk of Bias (RoB) 2 and Joanna Briggs Institute (JBI) Critical Appraisal tools were used for study quality assessment, as well as Review Manager (RevMan) 5.4 to perform the meta-analysis. RESULTS A total of ten studies were included in this systematic review. Six studies assessed the effect of probiotics consumption after colonoscopy, three examined the impact before colonoscopy, and one study assessed both. The most common type of probiotics used were Lactobacillus and Bifidobacterium. Quantitative synthesis of probiotics before colonoscopy showed no significant differences among bloating, abdominal pain, nausea, and vomiting symptoms (p=0.49, p=0.14, p=0.30, and p=0.42, respectively). Similarly, quantitative synthesis of probiotics after colonoscopy showed no significant differences in bloating and abdominal pain (p=0.16 and p=0.63, respectively). CONCLUSIONS Probiotic administration pre- and post-colonoscopy exhibited preliminary evidence for reducing gastrointestinal symptoms, but a quantitative synthesis revealed non-significant findings, necessitating further investigations.

Abstract
BACKGROUND/AIMS Assessment of quality of magnetic resonance enterography (MRE) in small bowel Crohn's disease (CD) activity evaluation has received little attention. We assessed the impact of bowel distention and motion artifact on MRE activity indices in ileal CD. METHODS A cohort of patients who underwent contemporaneous MRE and colonoscopy for ileal CD assessment between 2014 and 2021 at 2 centers were audited. An abdominal radiologist blinded to clinical data reviewed each MRE, graded bowel distention and motion artifact upon a pre-specified 3-point scale and calculated the original magnetic resonance index of activity (MaRIA) and simplified MaRIA (sMaRIA), London index and CD MRE index (CDMI). Ileal endoscopic activity was graded via the Simplified Endoscopy Score for CD (SES-CD). The performance of MRE indices in discriminating active disease (SES-CD ≥3) stratified by MRE quality was measured by receiver operator characteristic analyses. RESULTS One hundred and thirty-seven patients had MRE and colonoscopy within a median of 16 days (range, 0-30 days) with 63 (46%) exhibiting active disease (SES-CD ≥3). Forty-four MREs (32%) were deemed low quality due to motion artifact and/or moderate to poor distention. Low-quality MREs demonstrated reduced discriminative performance between ileal SES-CD ≥3 and MRE indices (MaRIA 0.838 vs. 0.634, sMaRIA 0.834 vs. 0.527, CDMI 0.850 vs. 0.595, London 0.748 vs. 0.511, P<0.05 for all). Individually the presence of any motion artifact markedly impacted the discriminative performance (e.g., sMaRIA area under the curve 0.544 vs. 0.814, P<0.05). CONCLUSIONS Image quality parameters can significantly impact MRE disease activity interpretation. Quality metrics should be reported, enabling cautious interpretation in lower-quality studies.

Abstract
Colonoscopy is an integral part of the lower bowel care and is generally considered a potentially safe diagnostic and therapeutic procedure performed as a daycare outpatient procedure. Colonoscopy is associated with different complications that are not limited to adverse events related to the bowel preparation solutions used, the sedatives used, but to the procedure related as well including bleeding and perforation. Injuries to the extra-luminal abdominal organs during colonoscopy are uncommon, however, serious complications related to the procedure have been reported infrequently in the literature. Life threatening injuries to the spleen, liver, pancreas, mesentery, and urinary bladder have been reported as early as in mid-1970s. These injuries should not be overlooked by clinicians and endoscopists. Steadily increasing abdominal pain, abdominal distension, and hemodynamic instability in absence of rectal bleeding should raise the possibility of severe organ injury. Splenic and hepatic injury following colonoscopy are usually serious and may be life threatening. Although conservative management may help, yet they usually need interventional radiology or surgical intervention. Acute pancreatitis following colonoscopy is usually mild and is mostly managed conservatively. The mechanism of abdominal organ injuries during colonoscopy is not fully understood, however many risk factors have been identified, which can be classified as- organ related, procedure related, and local abdominal factors. Difficult colonoscopy and prior intra-abdominal adhesions are probably the most relevant risk factors for these injuries. Left lateral position, avoidance of looping and excessive force during the procedure would probably reduce the risk of such injuries.

Abstract
Inflammatory bowel disease (IBD) flare-ups exhibit symptoms that are similar to other diseases and conditions, making diagnosis and treatment complicated. Currently, the gold standard for diagnosing and monitoring IBD is colonoscopy and biopsy, which are invasive and uncomfortable procedures, and the fecal calprotectin test, which is not sufficiently accurate. Therefore, it is necessary to develop an alternative method. In this study, our aim was to provide proof of concept for the application of Sequential Window Acquisition of All Theoretical Mass Spectra-Mass spectrometry (SWATH-MS) and machine learning to develop a non-invasive and accurate predictive model using the stool proteome to distinguish between active IBD patients and symptomatic non-IBD patients. Proteome profiles of 123 samples were obtained and data processing procedures were optimized to select an appropriate pipeline. The differentially abundant analysis identified 48 proteins. Utilizing correlation-based feature selection (Cfs), 7 proteins were selected for proceeding steps. To identify the most appropriate predictive machine learning model, five of the most popular methods, including support vector machines (SVMs), random forests, logistic regression, naive Bayes, and k-nearest neighbors (KNN), were assessed. The generated model was validated by implementing the algorithm on 45 prospective unseen datasets; the results showed a sensitivity of 96% and a specificity of 76%, indicating its performance. In conclusion, this study illustrates the effectiveness of utilizing the stool proteome obtained through SWATH-MS in accurately diagnosing active IBD via a machine learning model.

de Voogd FA, Bots SJ, van Wassenaer EA, de Jong M, Pruijt MJ, D'Haens GR, Gecse KB. Early Intestinal Ultrasound Predicts Clinical and Endoscopic Treatment Response and Demonstrates Drug-Specific Kinetics in Moderate-to-Severe Ulcerative Colitis. Inflamm Bowel Dis 2023:izad274. [PMID: 38011801 DOI: 10.1093/ibd/izad274] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2023] [Indexed: 11/29/2023]
Abstract
BACKGROUND Intestinal ultrasound (IUS) is an emerging modality in monitoring disease activity in ulcerative colitis (UC). Here, we aimed to identify early IUS predictors of treatment response as evaluated by endoscopy and assessed the kinetics of IUS changes. METHODS This prospective, longitudinal study included UC patients with endoscopic disease activity (endoscopic Mayo score [EMS] ≥2) starting anti-inflammatory treatment. Clinical scores, biochemical parameters and IUS were assessed at baseline (W0), at week 2 (W2), at W6(W6), and at the time of second endoscopy (W8-W26). Per colonic segment, endoscopic remission (EMS = 0), improvement (EMS ≤1), response (decrease in EMS ≥1), and clinical remission (Lichtiger score ≤3) were assessed and correlated with common IUS parameters. Additionally, drug-specific responsiveness of bowel wall thickness (BWT) was assessed. RESULTS A total of 51 patients were included and followed, and 33 patients underwent second endoscopy. BWT was lower from W6 onward for patients reaching endoscopic improvement (3.0 ± 1.2 mm vs 4.1 ± 1.3 mm; P = .026), remission (2.5 ± 1.2 mm vs 4.1 ± 1.1 mm; P = .002), and clinical remission (3.01 ± 1.34 mm vs 3.85 ± 1.20 mm; P = .035). Decrease in BWT was more pronounced in endoscopic responders (-40 ± 25% vs -4 ± 28%; P = .001) at W8 to W26. At W6, BWT ≤3.0 mm (odds ratio [OR], 25.13; 95% confidence interval, 2.01-3.14; P = .012) and color Doppler signal (OR, 0.35; 95% confidence interval, 0.14-0.88; P = .026) predicted endoscopic remission and improvement, respectively. Submucosal layer thickness at W6 predicted endoscopic remission (OR, 0.09; P = .018) and improvement (OR, 0.14; P = .02). Furthermore, BWT decreased significantly at W2 for infliximab and tofacitinib and at W6 for vedolizumab. CONCLUSIONS BWT and color Doppler signal predicted endoscopic targets already after 6 weeks of treatment and response was drug specific. IUS allows close monitoring of treatment in UC and is a surrogate marker of endoscopy.

Abstract
BACKGROUND Colonoscopy is difficult to learn. Virtual reality simulation training is helpful, but how and when novices should progress to patient-based training has yet to be established. To date, there is no assessment tool for credentialing novice endoscopists prior to clinical practice. The aim of this study was to develop such an assessment tool based on metrics provided by the simulator. The metrics used for the assessment tool should be able to discriminate between novices, intermediates, and experts and include essential checklist items for patient safety. METHODS The validation process was conducted based on the Standards for Educational and Psychological Testing. An expert panel decided upon three essential checklist items for patient safety based on Lawshe's method: perforation, hazardous tension to the bowel wall, and cecal intubation. A power calculation was performed. In this study, the Simbionix GI Mentor II simulator was used. Metrics with discriminatory ability were identified with variance analysis and combined to form an aggregate score. Based on this score and the essential items, pass/fail standards were set and reliability was tested. RESULTS Twenty-four participants (eight novices, eight intermediates, and eight expert endoscopists) performed two simulated colonoscopies. Four metrics with discriminatory ability were identified. The aggregate score ranged from 4.2 to 51.2 points. Novices had a mean score of 10.00 (SD 5.13), intermediates 24.63 (SD 7.91), and experts 30.72 (SD 11.98). The difference in score between novices and the other two groups was statistically significant (p<0.01). Although expert endoscopists had a higher score, the difference was not statistically significant (p=0.40). Reliability was good (Cronbach's alpha=0.86). A pass/fail score was defined at 17.1 points with correct completion of three essential checklist items, resulting in three experts and three intermediates failing and one novice passing the assessment. CONCLUSION We established a valid and reliable assessment tool with a pass/fail standard on the simulator. We suggest using the assessment after simulation-based training before commencing work-based learning.

Abstract
We present a patient who developed an ileocolic intussusception within a few hours of undergoing an endoscopic polypectomy found on screening colonoscopy. She underwent a laparoscopic right hemicolectomy with intracorporeal anastomosis. Final histopathological examination showed no evidence of malignancy. Intussusception after colonoscopy is a rare complication, and only 11 cases have been reported prior to this case. Laparoscopic resection with intracorporeal anastomosis is a safe and feasible option in patients who are not candidates or failed conservative management.

Abstract
Autoimmune diseases (AIDs) are poorly understood clinical syndromes due to breakdown of immune tolerance towards specific types of self-antigens. They are generally associated with an inflammatory response mediated by lymphocytes T, autoantibodies or both. Ultimately, chronic inflammation culminates in tissue damages and clinical manifestations. AIDs affect 5% of the world population, and they represent the main cause of fatality in young to middle-aged females. In addition, the chronic nature of AIDs has a devastating impact on the patient's quality of life. It also places a heavy burden on the health care system. Establishing a rapid and accurate diagnosis is considered vital for an ideal medical management of these autoimmune disorders. However, for some AIDs, this task might be challenging. Vibrational spectroscopies, and more particularly Fourier-transform infrared (FTIR) spectroscopy, have emerged as universal analytical techniques with promising applications in the diagnosis of various types of malignancies and metabolic and infectious diseases. The high sensitivity of these optical sensing techniques and their minimal requirements for test reagents qualify them to be ideal analytical techniques. The aim of the current review is to explore the potential applications of FTIR spectroscopy in the diagnosis and management of most common AIDs. It also aims to demonstrate how this technique has contributed to deciphering the biochemical and physiopathological aspects of these chronic inflammatory diseases. The advantages that can be offered by this optical sensing technique over the traditional and gold standard methods used in the diagnosis of these autoimmune disorders have also been extensively discussed.

Abstract
PURPOSE This study was conducted to examine the effect of progressive muscle relaxation on abdominal pain and distension in colonoscopy patients. DESIGN A randomized controlled experimental design. METHODS The experimental group was informed about progressive muscle relaxation (PMR) and an audio recording was provided. After the colonoscopy, abdominal pain (Visual Analogue Scale (VAS) pain) and distension (VAS distension) scores were assessed, then PMR was applied for 30 minutes and pain scores were determined again. VAS pain and VAS distension scores of the control group were determined after colonoscopy and 30 minutes later. VAS abdominal pain and VAS distension scores were evaluated at the 2nd, 4th, 8th, 12th, 16th, and 24th hour after the procedure on all patients. The day after the colonoscopy, post-test data were collected. FINDINGS The pretest VAS pain and VAS distension mean scores were similar in the intervention and control groups (P > .05). The mean VAS pain and VAS distension scores decreased significantly in the intervention group post procedure (P < .05). CONCLUSIONS PMR was determined to be effective in reducing abdominal pain and distension after colonoscopy.

Benefits of Probiotic Pretreatment on the Gut Microbiota and Minor Complications after Bowel Preparation for Colonoscopy: A Randomized Double-Blind, Placebo-Controlled Pilot Trial. Nutrients 2023; 15:nu15051141. [PMID: 36904141 PMCID: PMC10004836 DOI: 10.3390/nu15051141] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 02/18/2023] [Accepted: 02/22/2023] [Indexed: 03/12/2023] Open
Abstract
The aim of this study was to evaluate the effects of probiotic pretreatment on the alteration and recovery of gut microbiota after bowel preparation and its correlation with minor complications. This was a randomized, double-blind, placebo-controlled pilot trial that included participants 40-65 years of age. Participants were randomly provided probiotics (active group) or placebo (placebo group) for 1 month before the colonoscopy and their feces collected. A total of 51 participants were included in the present study (26 in the active group and 25 in the placebo group). In the active group, the microbial diversity, evenness, and distribution were not significantly changed between before and after bowel preparation, but did change in the placebo group. The number of gut microbiota that decreased after bowel preparation in the active group was lower than in the placebo group. On the seventh day after colonoscopy, the gut microbiota in the active group was restored to almost the same level as before bowel preparation. In addition, we identified that several strains were assumed as key microbiota in early colonization and some taxa were increased only in the active group after bowel preparation. In multivariate analysis, taking probiotics before bowel preparation was identified as a significant factor for decreasing the duration of minor complications (odds ratio 0.13, 95% confidence interval 0.02-0.60, p = 0.027). Probiotic pretreatment had benefits on the alteration and recovery of gut microbiota and possible complications after bowel preparation. Probiotics may also aid in the early colonization of key microbiota.

Abstract
The clinical usefulness of repeat colonoscopic polypectomy in patients with numerous polyps has not been sufficiently determined. We aimed to analyze the clinical outcomes of colonoscopic polypectomy with surveillance colonoscopies in patients with ≥ 10 polyps. We reviewed the medical records of 152 patients who underwent polypectomy of ≥ 10 polyps at the baseline colonoscopy. We investigated polyp number, polyp size, polypectomy method, procedure time, and adverse events of the baseline colonoscopy. We also investigated the frequency and interval of surveillance colonoscopies and their findings. The mean number of polyps detected at the baseline colonoscopy was 20.0, of which 16.0 polyps were endoscopically resected. The mean size of the largest polyp was 13.4 mm. The mean procedure time was 54.9 min. Post-polypectomy bleeding occurred in 6 (3.9%) patients, all of whom were treated conservatively. No patients developed perforation. With an increasing number of surveillance colonoscopies, the number of detected polyps and the procedure time decreased. Surveillance colonoscopies identified colorectal cancer only in three patients (2.0%), all of which were mucosal cancers that could be curatively treated by polypectomy. Colonoscopic polypectomy with repeat surveillance colonoscopies is a clinically effective, efficient, and safe management option in patients with ≥ 10 polyps.

Abstract
BACKGROUND AND AIMS Motorized spiral enteroscopy (MSE) has been postulated to ease the complexities of the standard-of-care double-balloon enteroscopy (DBE). However, there are no comparative studies between MSE and DBE. This study aimed to compare the therapeutic outcomes and safety between MSE and DBE. METHODS In this case-matched study, patients were matched 1:2 (MSE/DBE) by age, sex, body mass index, and American Society of Anesthesiology scores. Thirty-one patients who underwent MSE were compared with 62 patients who underwent DBE from 2014 to 2022. Our primary outcomes were to compare the technical and diagnostic success rates between DBE and MSE. Our secondary outcomes were to compare the therapeutic success and adverse event rates. RESULTS The main indications for enteroscopy were suspected GI bleeding and positive radiologic findings. Prior abdominal surgery was reported in 35.5% and 22.6% of DBE and MSE patients, respectively. Most were antegrade enteroscopy (71%). We found no significant difference in the technical success (DBE 98.4% vs MSE 96.8%, P = .62), diagnostic success (DBE 66.1% vs MSE 54.8%, P = .25), and therapeutic success rates (DBE 62.8% vs MSE 52.9%, P = .62) between the groups. Adverse events occurred in 1 DBE and 11 MSE patients. Most were minor (n = 10, 25.6%). Two patients (5.1%) in the MSE group sustained deep lacerations in the proximal esophagus requiring hospitalization. One developed ileal perforation after MSE needing surgical repair. CONCLUSIONS In patients requiring enteroscopy, the diagnostic and therapeutic performance of MSE is similar to DBE. An increased frequency of adverse events was observed with MSE. There are some restrictions in the indication because of the design of MSE.

Abstract
BACKGROUND AND PURPOSE Endoscopic mucosal resection (EMR) is frequently used for the removal of colorectal neoplasms. However, the use of prophylactic antibiotics in patients undergoing EMR is debatable. The aim of this randomized controlled trial was to assess whether antimicrobial prophylaxis is crucial in the perioperative period of EMR, especially for 10- to 20-mm lesions in this setting. METHODS Two hundred and sixty-four patients were randomized equally into 2 groups, the antibiotic (cefixime) group and the control group. The occurrence of adverse events was examined at 1 to 3 days after EMR. Plasma levels of inflammatory markers were analyzed at pre-operation, 1 day post-operation and 3 days post-operation. Blood samples collected at 1 day post-operation were used for culture. RESULTS A total of 264 and 268 polyps were removed by EMR in the antibiotic group and the control group, respectively. There were 5 cases of fever, with 2 in the antibiotic group and 3 in the control group. In the antibiotic group, 12 patients had abdominal pain and 10 suffered bleeding, whereas in the control group, abdominal pain and bleeding were observed in 10 and 11 patients, respectively. There were no significant differences in the proportion of patients with fever or the incidences of postoperative complications between the groups. No significant differences between the groups were reported in plasma levels of white blood cell count, erythrocyte sedimentation rate, C-reactive protein or procalcitonin at pre-operation or post-operation. No patients provided positive blood cultures. CONCLUSIONS The use the prophylactic antibiotics for EMR procedures in the perioperative period is no longer required when the lesions are 10 to 20 mm in size.

Abstract
Cancer is one of the foremost health problems worldwide and is among the leading causes of death in the United States. Gastrointestinal tract cancers account for almost one third of the cancer-related mortality globally, making it one of the deadliest groups of cancers. Early diagnosis and prompt management are key to preventing cancer-related morbidity and mortality. With advancements in technology and endoscopic techniques, endoscopy has become the core in diagnosis and management of gastrointestinal tract cancers. In this extensive review, the authors discuss the role endoscopy plays in early detection, diagnosis, and management of esophageal, gastric, colorectal, pancreatic, ampullary, biliary tract, and small intestinal cancers.

Abstract
Gastrointestinal (GI) diseases are serious health threats to human health, and the related detection and treatment of gastrointestinal diseases place a huge burden on medical institutions. Imaging-based methods are one of the most important approaches for automated detection of gastrointestinal diseases. Although deep neural networks have shown impressive performance in a number of imaging tasks, its application to detection of gastrointestinal diseases has not been sufficiently explored. In this study, we propose a novel and practical method to detect gastrointestinal disease from wireless capsule endoscopy (WCE) images by convolutional neural networks. The proposed method utilizes three backbone networks modified and fine-tuned by transfer learning as the feature extractors, and an integrated classifier using ensemble learning is trained to detection of gastrointestinal diseases. The proposed method outperforms existing computational methods on the benchmark dataset. The case study results show that the proposed method captures discriminative information of wireless capsule endoscopy images. This work shows the potential of using deep learning-based computer vision models for effective GI disease screening.

Longitudinal assessment of colonoscopy adverse events in the prospective Cooperative Studies Program no. 380 colorectal cancer screening and surveillance cohort. Gastrointest Endosc 2022; 96:553-562.e3. [PMID: 35533738 PMCID: PMC9531542 DOI: 10.1016/j.gie.2022.04.1343] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2022] [Accepted: 04/30/2022] [Indexed: 02/08/2023]
Abstract
BACKGROUND AND AIMS Data are limited regarding colonoscopy risk during long-term, programmatic colorectal cancer screening and follow-up. We aimed to describe adverse events during follow-up in a colonoscopy screening program after the baseline examination and examine factors associated with increased risk. METHODS Cooperative Studies Program no. 380 includes 3121 asymptomatic veterans aged 50 to 75 years who underwent screening colonoscopy between 1994 and 1997. Periprocedure adverse events requiring significant intervention were defined as major events (other events were minor) and were tracked during follow-up for at least 10 years. Multivariable odds ratios (ORs) were calculated for factors associated with risk of follow-up adverse events. RESULTS Of 3727 follow-up examinations in 1983 participants, adverse events occurred in 105 examinations (2.8%) in 93 individuals, including 22 major and 87 minor events (examinations may have had >1 event). Incidence of major events (per 1000 examinations) remained relatively stable over time, with 6.1 events at examination 2, 4.8 at examination 3, and 7.2 at examination 4. Examinations with major events included 1 perforation, 3 GI bleeds requiring intervention, and 17 cardiopulmonary events. History of prior colonoscopic adverse events was associated with increased risk of events (major or minor) during follow-up (OR, 2.7; 95% confidence interval, 1.6-4.6). CONCLUSIONS Long-term programmatic screening and surveillance was safe, as major events were rare during follow-up. However, serious cardiopulmonary events were the most common major events. These results highlight the need for detailed assessments of comorbid conditions during routine clinical practice, which could help inform individual decisions regarding the utility of ongoing colonoscopy follow-up.

Abstract
Colonoscopy is one of the most commonly performed endoscopic procedures and remains the most commonly used screening modality method for colorectal cancer (CRC) screening in the USA. Although serious complications of fiberoptic colonoscopy are uncommon due to technical advances, due to increasing number of colonoscopy procedures, post-procedural complications are not uncommonly encountered in the routine clinical practice. Also, as some of the post-colonoscopy complications are life threatening, it is important to diagnose them early so that timely treatment measures can be taken to decrease mortality and morbidity. In this review, we present a case-based illustration of the utility of CT to detect complications of colonoscopy including bowel perforation, hemorrhage, splenic injury, and postpolypectomy syndrome.

Abstract
Background: Many studies have been done regarding perforation after colonoscopy, but few studies analyzed the risk factors of endoscopic treatment failure after colonoscopy perforation. This study aimed to analyze the clinical characteristics and treatment plan of those patients with perforation after colonoscopy diagnosis and the treatment and risk factors of failure to endoscopic treatment. Method: This was a retrospective observational study of patients who underwent colonoscopy examination and treatment at the Affiliated Hospital of Yangzhou University, from 04/2009 to 03/2020. The patients were grouped as perforation, treatment success, or failure (required laparoscopy or laparotomy). Results: From April 2009 to March 2020, 43,470 patients were examined and treated with colonoscopy. There were 35 cases of intestinal perforation, for an incidence of 0.081%. Four patients had immediate surgical intervention (two patients with laparoscopic surgery and two with laparotomy surgery). Thirty-one (88.57%) patients underwent endoscopic treatment. Endoscopic treatment was successful in 20 patients and failed in 11. Compared with the failure group, the perforation size in the success group was smaller (7.60±4.85 vs. 14.4±7.03 mm, P=0.004), hospital stay was shorter (26.6±13.1 vs. 14.2±3.0, P=0.011), and hospitalization costs were lower (30,208±9506 vs. 23,053±6227 RMB, P=0.002). Multivariable logistic stepwise analysis showed that the absence of abdominal pain after therapeutic colonoscopy was independently associated with the success of endoscopic treatment. Conclusions: Endoscopic treatment is logically the preferred modality for perforation management, leading to good recovery, shorter hospital stay, and lower costs of treatment. Postoperative abdominal pain is significantly related to the failure of endoscopic treatment.

Novel classification for adverse events in GI endoscopy: the AGREE classification. Gastrointest Endosc 2022; 95:1078-1085.e8.

Abstract
BACKGROUND AND AIMS Standardized registration and evaluation of adverse events (AEs) are essential to assess the safety of endoscopic procedures. We propose a novel classification system, named adverse events in GI endoscopy (AGREE), adapted from a widely accepted surgical tool. METHODS The Clavien-Dindo classification for surgical AEs was adapted for endoscopy. To validate the novel classification, we assessed if the severity of AEs, as perceived by 10 endoscopists, 10 endoscopy nurses, and 10 patients, corresponded with the severity grading used in the AGREE classification in 10 pairwise comparisons. We additionally assessed the correlation between the AGREE classification and the American Society for Gastrointestinal Endoscopy (ASGE) classification. The acceptability of the AGREE classification was evaluated through an international questionnaire. RESULTS The perception of endoscopists, endoscopy nurses, and patients corresponded with the severity grading of the AGREE classification in 80% of cases (238/299). The AGREE classification significantly correlated with the ASGE classification (ρ = .760). Fifty-seven of 84 experts (68%) completed a questionnaire regarding the acceptability of the AGREE classification. The experts consulted considered the AGREE classification as simple (86%), reproducible (98%), logical (98%), and useful (96%). Most case presentations (84%) were correctly graded according to the AGREE classification. CONCLUSIONS The AGREE classification provides a standardized and reproducible approach to the assessment of AEs in diagnostic and therapeutic GI endoscopy. Broad implementation of the AGREE classification may facilitate the evaluation of AEs across different endoscopists, disciplines, endoscopy services, and regions. This standardization of AE reporting will support improved quality assurance in GI endoscopy.

Abstract
BACKGROUND AND AIM Informed consent for endoscopy is variable across institutions and remains understudied in gastrointestinal endoscopy. This study aims to standardize informed consent for screening and diagnostic colonoscopies with a supplemental video tool that includes the key components of informed consent. METHODS A video tool was developed that incorporated the key components of informed consent for colonoscopy. In addition, a 7-question survey was developed to query patients on core aspects of informed consent and satisfaction with the informed consent process. Patients undergoing elective outpatient colonoscopy with conscious sedation were randomized to traditional consent or consent with the addition of a video tool. A pilot study determined the sample size. Traditional consent was standard of practice before the procedure. Patients in the video tool group watched the video tool in the preprocedure area followed by traditional consent. Both groups had the opportunity to address questions with the attending physician before the procedure. All patients were contacted 1 to 2 days following the colonoscopy to answer the question survey. RESULTS A total of 110 patients were eligible for participation, and 91 were included in the final data analysis. Subjects in the video tool group demonstrated significantly higher recall of key aspects of informed consent and higher satisfaction with the informed consent process versus the traditional consent group. The history of prior colonoscopy was similar between both groups. Mean endoscopy operation metrics were not negatively impacted by the inclusion of the video tool. CONCLUSION Patients undergoing screening and diagnostic colonoscopies who received informed consent supplemented by a video tool had a higher recall of core aspects of informed consent and higher satisfaction with the process, with no impact on procedural times.

Abstract
The 2 most significant complications of colonoscopy with polypectomy are bleeding and perforation. Although the incidence rates are generally low (<1%), these can be avoided by recognizing pertinent risk factors, which can be patient, polyp, and technique/device related. Endoscopists should be equipped to manage bleeding and perforation. Currently available devices and techniques to achieve hemostasis and manage colon perforations are reviewed.

Abstract
The efficiency of conventional screening programs to identify early-stage malignancies can be limited by the low number of cancers recommended for screening as well as the high cumulative false-positive rate, and associated iatrogenic burden, resulting from repeated multimodal testing. The opportunity to use minimally invasive liquid biopsy testing to screen asymptomatic individuals at-risk for multiple cancers simultaneously could benefit from the aggregated diseases prevalence and a fixed specificity. Increasing both latter parameters is paramount to mediate high positive predictive value—a useful metric to evaluate a screening test accuracy and its potential harm-benefit. Thus, the use of a single test for multi-cancer early detection (stMCED) has emerged as an appealing strategy for increasing early cancer detection rate efficiency and benefit population health. A recent flurry of these stMCED technologies have been reported for clinical potential; however, their development is facing unique challenges to effectively improve clinical cost–benefit. One promising avenue is the analysis of circulating tumour DNA (ctDNA) for detecting DNA methylation biomarker fingerprints of malignancies—a hallmark of disease aetiology and progression holding the potential to be tissue- and cancer-type specific. Utilizing panels of epigenetic biomarkers could potentially help to detect earlier stages of malignancies as well as identify a tumour of origin from blood testing, useful information for follow-up clinical decision making and subsequent patient care improvement. Overall, this review collates the latest and most promising stMCED methodologies, summarizes their clinical performances, and discusses the specific requirements multi-cancer tests should meet to be successfully implemented into screening guidelines.

Abstract
BACKGROUND & AIMS Nonpedunculated colorectal polyps are normally endoscopically removed to prevent neoplastic progression. Delayed bleeding is the most common major adverse event. Clipping the resection defect has been suggested to reduce delayed bleedings. Our aim was to determine if prophylactic clipping reduces delayed bleedings and to analyze the contribution of polyp characteristics, extent of defect closure, and antithrombotic use. METHODS An individual patient data meta-analysis was performed. Studies on prophylactic clipping in nonpedunculated colorectal polyps were selected from PubMed, Embase, Web of Science, and Cochrane database (last selection, April 2020). Authors were invited to share original study data. The primary outcome was delayed bleeding ≤30 days. Multivariable mixed models were used to determine the efficacy of prophylactic clipping in various subgroups adjusted for confounders. RESULTS Data of 5380 patients with 8948 resected polyps were included from 3 randomized controlled trials, 2 prospective, and 8 retrospective studies. Prophylactic clipping reduced delayed bleeding in proximal polyps ≥20 mm (odds ratio [OR], 0.62; 95% confidence interval [CI], 0.44-0.88; number needed to treat = 32), especially with antithrombotics (OR, 0.59; 95% CI, 0.35-0.99; number needed to treat = 23; subgroup of anticoagulants/double platelet inhibitors: n = 226; OR, 0.40; 95% CI, 0.16-1.01; number needed to treat = 12). Prophylactic clipping did not benefit distal polyps ≥20 mm with antithrombotics (OR, 1.41; 95% CI, 0.79-2.52). CONCLUSIONS Prophylactic clipping reduces delayed bleeding after resection of nonpedunculated, proximal colorectal polyps ≥20 mm, especially in patients using antithrombotics. No benefit was found for distal polyps. Based on this study, patients can be identified who may benefit from prophylactic clipping. (PROSPERO registration number CRD42020104317.).

Abstract
BACKGROUND AND STUDY AIMS Ischemic colitis (IC) may occur as a complication of colonoscopy. The aim of this study was to characterize patients with IC that occurred after exposure to bowel preparation laxatives, prior to an elective colonoscopy. PATIENTS AND METHODS A survey among Israeli gastroenterologists. Information was collected regarding individual cases. RESULTS Eight patients, who developed IC after bisacodyl ingestion that was taken as part of pre-colonoscopy bowel preparation protocol, were reported. In all patients, severe abdominal pain and/or hematochezia started shortly after the ingestion of the first dose of bisacodyl. IC was found in 7 patients during the planned colonoscopy and in 1 patient using computerized tomography. All patients received supportive treatment and recovered. CONCLUSIONS IC induced by bisacodyl is a rare phenomenon. Regardless of being rare, we would advise withholding bisacodyl bowel preparation in elderly subjects with risk factors for IC that are scheduled for a colonoscopy.

Abstract
BACKGROUND The risk for bacteremia following endoscopic procedures varies among studies. A low neutrophil count is considered as a risk factor. OBJECTIVE To assess risk factors for bacteremia following endoscopic procedures, focusing on neutropenia. METHODS This was a retrospective analysis of all inpatients undergoing endoscopic procedures between 2005 and 2018 with neutrophil count taken within 72 hours before the procedure in a tertiary center in Israel. The primary outcome was positive blood culture within 48 hours following the procedure of bacteria that was not cultured before. Risk factors for bacteremia were assessed and multivariate logistic regression models were built. In neutropenic patients, comparator groups were used to assess the risk related to the procedure and neutropenia. RESULTS Of 13,168 patients included, postprocedural bacteremia was recorded in 103 (0.8%). Neutropenia, low albumin level, male gender, older age, preprocedure fever, and admitting department were associated with increased risk for bacteremia in both univariate and multivariate analyses. A multivariate model including these factors was found to be predictive of bacteremia (area under the curve 0.82; 95% confidence interval, 0.78-0.88). In neutropenic patients, the risk of postendoscopic bacteremia (4.2%) was not significantly different compared with neutropenic patients undergoing bronchoscopy (1.8%, P=0.14) or from the rate of bacteremia-to-neutropenic episodes ("background risk") in neutropenic patients in general (6.3%, P=0.33). CONCLUSIONS Postendoscopic bacteremia is a rare event among inpatients. Although neutropenia was found to be a risk factor for bacteremia, it was not higher than the background risk in these patients. Models highly predictive of bacteremia were developed and should be validated.

Abstract
The incidence of complications after colonoscopy is low and has been reported to range of 0.01–0.9%. Of these complications, colocolonic intussusception after colonoscopy is exceedingly rare, with around 12 known cases described in the literature. This case report details the presentation and operative management of a patient who developed an ischemic stoma due to a colocolonic intussusception of an end colostomy after a colonoscopy. Intraoperative surgical exploration revealed a colocolonic intussusception involving the end colostomy. This is the first known documented occurrence of this phenomenon.

Efficacy of endoscopic surveillance in the detection of local recurrence after radical rectal cancer surgery is limited? A retrospective study. World J Surg Oncol 2021; 19:308. [PMID: 34670554 PMCID: PMC8529797 DOI: 10.1186/s12957-021-02413-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2021] [Accepted: 09/30/2021] [Indexed: 01/19/2023] Open
Abstract
Background Rectal cancer, one of most common neoplasms, is characterized by an overall survival rate exceeding 60%. Nonetheless, local recurrence (LR) following surgery for rectal cancer remains a formidable clinical problem. The aim of this study was to assess the value of postoperative endoscopic surveillance (PES) for the early detection of LR in rectal cancer after radical anterior resection with sigmoid-rectal anastomosis. Methods We performed an anterior resection in 228 patients with stages I‑III rectal cancer who had undergone surgery from 2001 to 2008 in the Oncology Center in Bydgoszcz, Poland. Of these patients, 169 had perioperative radiotherapy or radiochemotherapy. All patients underwent PES with abdominal and pelvic imaging (abdominal ultrasound, computed tomography, magnetic resonance) and clinical examination. Sensitivities, specificities, positive likelihood ratios, negative likelihood ratios, and receiver operating characteristic curves were calculated to compare the value of colonoscopy versus imaging techniques for the diagnosis of LR. Results During the 5-year follow-up, recurrences occurred in 49 (21%) patients; of these, 15 (6%) had LR, which was most often located outside the intestinal lumen (n = 10, 4%). Anastomotic LR occurred in 5 (2%) patients. The mean time to anastomotic LR was 30 months after initial surgery, similar to that of other locations (29 months). Both imaging and endoscopy were shown to be efficient techniques for the diagnosis of LR in anastomotic sites. In the study group, endoscopy did not provide any additional benefit in patients who were receiving radiation therapy. Conclusions The benefit of PES for the detection of LR after curative treatment of rectal cancer is limited and not superior to imaging techniques. It remains a useful method, however, for the histopathological confirmation of suspected or confirmed recurrence.

Endoscopic characteristics influencing postpolypectomy bleeding in 1147 consecutive pedunculated colonic polyps: a multicenter retrospective study. Gastrointest Endosc 2021; 94:803-811.e6.

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.

Normalization of Fecal Calprotectin Within 12 Months of Diagnosis Is Associated With Reduced Risk of Disease Progression in Patients With Crohn's Disease. Clin Gastroenterol Hepatol 2021; 19:1835-1844.e6. [PMID: 32798706 DOI: 10.1016/j.cgh.2020.08.022] [Citation(s) in RCA: 21] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/11/2019] [Revised: 07/08/2020] [Accepted: 08/07/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS The level of fecal calprotectin (FC) correlates with endoscopic evidence of inflammation in Crohn's disease (CD). A treat-to-target algorithm for patients with CD, that incorporates FC, outperforms a treatment strategy based on symptoms alone in the induction of mucosal healing at 12 months. We investigated whether normalization of FC within 12 months of diagnosis of CD is associated with a reduction in disease progression. METHODS We performed a retrospective cohort study at a tertiary IBD centre in the United Kingdom. We identified all incident cases of CD diagnosed from 2005 through 2017. Patients with a FC measurement ≥250 μg/g at diagnosis who also had at least 1 follow-up FC measurement within the first 12 months of diagnosis and >12 months of follow up were included. The last FC measurement within 12 months of diagnosis was used to determine normalization (cut-off <250 μg/g). The primary endpoint was time to first disease progression (composite of progression in Montreal disease behavior B1 to B2/3, B2 to B3, or new perianal disease; CD-related surgery; or CD-related hospitalization). Cox proportional hazards regression analysis was used to determine independent factors associated with time to first disease progression. RESULTS A total of 375 patients out of 1389 incident cases were included, with a median follow up of 5.3 years (interquartile range, 3.1-7.4 years). Normalization of FC within 12 months of diagnosis was confirmed in 43.5% of patients. Patients with normalized levels of FC had a significantly lower risk of composite disease progression (hazard ratio [HR], 0.36; 95% CI, 0.24-0.53; P < .001). They also had a lower risk of reaching any of the separate progression endpoints (progression in Montreal behavior or new perianal disease HR, 0.22; 95% CI, 0.11-0.45; P < .001; hospitalization HR, 0.33; 95% CI, 0.21-0.53; P <.001; surgery HR, 0.39; 95% CI, 0.19-0.78; P = .008) CONCLUSIONS: Normalization of FC within 12 months of diagnosis is associated with a reduced risk of progression of CD.

Abstract
Colorectal cancer remains a leading cause of morbidity and mortality in the United States. Advances in artificial intelligence (AI), specifically computer aided detection and computer-aided diagnosis offer promising methods of increasing adenoma detection rates with the goal of removing more pre-cancerous polyps. Conversely, these methods also may allow for smaller non-cancerous lesions to be diagnosed in vivo and left in place, decreasing the risks that come with unnecessary polypectomies. This review will provide an overview of current advances in the use of AI in colonoscopy to aid in polyp detection and characterization as well as areas of developing research.

Effect of prophylactic clip application for the prevention of postpolypectomy bleeding of large pedunculated colonic polyps: a randomized controlled trial. Gastrointest Endosc 2021; 94:148-154. [PMID: 33417897 DOI: 10.1016/j.gie.2020.12.040] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2020] [Accepted: 12/20/2020] [Indexed: 12/11/2022]
Abstract
BACKGROUND AND AIMS Prophylactic application of a hemoclip has been suggested as an alternative to the use of an endoloop for the prevention of postpolypectomy bleeding (PPB) when resecting large, pedunculated colorectal polyps. Therefore, this multicenter, randomized controlled trial investigated the efficacy of prophylactic hemoclip application to reduce PPB during the resection of large pedunculated polyps. METHODS Large pedunculated polyps (≥10 mm in head diameter) were eligible for inclusion. Polyps were randomized into a study arm (where clips were applied before resection) and a control arm (without pretreatment). The primary outcome was the rate of PPB in each group. PPB included immediate PPB (IPPB) and delayed PPB (DPPB). IPPB was defined as blood oozing (≥1 minute) or active spurting occurring immediately after polyp resection. DPPB was defined as rectal bleeding, occurring after completion of the colonoscopy. RESULTS In total, 238 polyps from 204 patients were randomized into the clip arm (119 polyps) or the control arm (119 polyps). Overall bleeding adverse events were observed in 20 cases (IPPB, 16; DPPB, 4). The rate of overall PPB, IPPB, and DPPB was 8.4%, 6.7%, and 1.7%, respectively, for all polyps. The rate of overall PPB (clip 4.2% vs control 12.6%, P = .033) and IPPB (clip 2.5% vs control 10.9%, P = .017) was significantly lower in the clip arm than the control arm. CONCLUSIONS Prophylactic clipping before resecting large pedunculated polyps can reduce overall PPB and IPPB compared with no prior treatment. Therefore, prophylactic clipping may be considered before resection of large pedunculated polyps. (Clinical trial registration number: NCT02156193.).

Abstract
Cystic Fibrosis (CF) is the commonest inherited genetic disorder in Caucasians due to a mutation in the gene CFTR (Cystic Fibrosis Transmembrane Conductance Regulator), and it should be considered as an Inherited Colorectal Cancer (CRC) Syndrome. In the United States, physicians of CF Foundation established the “Developing Innovative Gastroenterology Speciality Training Program” to increase the research on CF in gastrointestinal and hepatobiliary diseases. The risk to develop a CRC is 5–10 times higher in CF patients than in the general population and even greater in CF patients receiving immunosuppressive therapy due to organ transplantation (30-fold increased risk relative to the general population). Colonoscopy should be considered the best screening for CRC in CF patients. The screening colonoscopy should be started at the age of 40 in CF patients and, if negative, a new colonoscopy should be performed every 5 years and every 3 years if adenomas are detected. For transplanted CF patients, the screening colonoscopy could be started at the age of 35, in transplanted patients at the age of 30 and, if before, at the age of 30. CF transplanted patients, between the age of 35 and 55, must repeat colonoscopy every 3 years. Our review draws attention towards the clinically relevant development of CRC in CF patients, and it may pave the way for further screenings and studies.

Abstract
Irritable bowel syndrome (IBS) is a highly prevalent disorder of gut-brain interaction, which significantly erodes the quality of life of those it affects. Recent studies have confirmed that its prevalence varies quite markedly between countries, implying that it is affected by cultural and socioeconomic factors. In an important study, Silvernale at al. have recently reported racial disparities including potential referral biases, with reduced opportunities to access specialist care and differing patterns of healthcare utilization affecting ethnic minority populations with IBS. Similar disparities have also been reported for other gastrointestinal disorders. In this paper, we, therefore, discuss the potential implications of such disparities and how they can impact clinical outcomes, and discuss ways in which this problem could be addressed, and highlighting areas for future research.

Abstract
OBJECTIVE To estimate the cost-effectiveness of multitarget stool DNA testing (MT-sDNA) compared with colonoscopy and fecal immunochemical testing (FIT) for Alaska Native adults. PATIENTS AND METHODS A Markov model was used to evaluate the 3 screening test effects over 40 years. Outcomes included colorectal cancer (CRC) incidence and mortality, costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs). The study incorporated updated evidence on screening test performance and adherence and was conducted from December 15, 2016, through November 6, 2019. RESULTS With perfect adherence, CRC incidence was reduced by 52% (95% CI, 46% to 56%) using colonoscopy, 61% (95% CI, 57% to 64%) using annual FIT, and 66% (95% CI, 63% to 68%) using MT-sDNA. Compared with no screening, perfect adherence screening extends life by 0.15, 0.17, and 0.19 QALYs per person with colonoscopy, FIT, and MT-sDNA, respectively. Colonoscopy is the most expensive strategy: approximately $110 million more than MT-sDNA and $127 million more than FIT. With imperfect adherence (best case), MT-sDNA resulted in 0.12 QALYs per person vs 0.05 and 0.06 QALYs per person by FIT and colonoscopy, respectively. Probabilistic sensitivity analyses supported the base-case analysis. Under varied adherence scenarios, MT-sDNA either dominates or is cost-effective (ICERs, $1740-$75,868 per QALY saved) compared with FIT and colonoscopy. CONCLUSION Each strategy reduced costs and increased QALYs compared with no screening. Screening by MT-sDNA results in the largest QALY savings. In Markov model analysis, screening by MT-sDNA in the Alaska Native population was cost-effective compared with screening by colonoscopy and FIT for a wide range of adherence scenarios.

Abstract
Pancreatic cancer is projected to become the second leading cause of cancer-related death in the United States by 2020. Because of this, significant interest and research funding has been devoted to development of a screening test to identify individuals during a prolonged asymptomatic period; however, to date, no such test has been developed. We evaluated current NIH spending and clinical trials to determine the focus of research on pancreatic cancer screening as compared with other cancer subtypes. Using statistical methodology, we determined the effects of population-based pancreatic cancer screening on overall population morbidity and mortality. Population-based pancreatic cancer screening would result in significant harm to non-diseased individuals, even in cases where a near-perfect test was developed. Despite this mathematical improbability, NIH funding for pancreatic cancer demonstrates bias toward screening test development not seen in other cancer subtypes. Focusing research energy on development of pancreatic screening tests is unlikely to result in overall survival benefits. Efforts to increase the number of patients who are candidates for surgery and improving surgical outcomes would result in greater population benefit.Prevention Relevance: For patients with pancreatic cancer, early stage detection offers the greatest survival benefit. However, the incidence of pancreatic cancer and associated mortality of pancreatic resections make development of a screening test a difficult, if not impossible, challenge.

Abstract
In the United States, colorectal cancer (CRC) is the second leading cause of mortality in men and women. We are now seeing an increasing number of patients with advanced-stage diagnosis and mortality from colorectal cancer before 50 years of age, which requires earlier screening. With the increasing need for CRC screening through colonoscopy, and thus endoscopists, easier and simpler techniques are needed to train proficient endoscopists. The most widely used approach by endoscopists is air insufflation colonoscopy, where air distends the colon to allow visualization of the colonic mucosa. This technique is un-comfortable for patients and requires an anesthetist to administer sedation. In addition, patients commonly complain about discomfort post-op as air escapes into the small bowel and cannot be adequately removed. Current research into the use of water insufflation colonoscopies has proved promising in reducing the need for sedation, decreasing discomfort, and increasing the visibility of the colonic mucosa. Future direction into water insufflation colonoscopies which have shown to be simpler and easier to teach may increase the number of proficient endoscopists in training to serve our aging population.

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.

Abstract
Background/Aims Minor complications that might occur after colonoscopy, including abdominal discomfort, bloating, diarrhea, and constipation, could a barrier for patients to undergo a screening colonoscopy. In this study, we aimed to identify the effect of gut microbial diversity and composition on minor complications after colonoscopy. Methods A total of 24 healthy subjects provided their stools before bowel preparation and on the 7th and 28th day after colonoscopy. On the 7th day after colonoscopy, the presence of minor complications was investigated using a questionnaire. We divided patients into 2 groups, the no complication group and complications group. The fecal microbial diversity, distribution, and composition were then compared between the groups. Results Five of the 24 subjects reported that they had undergone minor complications after colonoscopy. Most of the symptoms were mild and self-limited, but 1 patient needed medication. Interestingly, the Firmicutes/Bacteroidetes ratio of the initial stool samples before bowel preparation in the complication group was significantly higher than that in no complication group. After bowel preparation, the Firmicutes/Bacteroidetes ratio of the complication group decreased, but not in the no complication group. The microbial diversity of the no complication group decreased after bowel preparation, but not in the complication group. Conclusions The gut microbial composition and diversity before and after bowel preparation could be considered as one of the causes of minor complications after colonoscopy. Further studies are needed to delineate the role of gut microbiota in the occurrence of minor complications after colonoscopy.

Abstract
BACKGROUND AND AIMS Colonoscopy quality indicators such as adenoma detection rate (ADR) are surrogates for the effectiveness of screening-related colonoscopy. It is unclear whether endoscopist feedback on these indicators improves performance. We performed a meta-analysis to determine whether associations exist between endoscopist feedback and colonoscopy performance. METHODS We conducted a search through May 2019 for studies reporting on endoscopist feedback and associations with ADR or other colonoscopy quality indicators. Pooled rate ratios (RRs) and weighted mean differences were calculated using DerSimonian and Laird random effects models. Subgroup, sensitivity, and meta-regression analyses were performed to assess for potential methodological or clinical factors associated with outcomes. RESULTS From 1326 initial studies, 12 studies were included in the meta-analysis for ADR, representing 33,184 colonoscopies. Endoscopist feedback was associated with an improvement in ADR (RR, 1.21; 95% confidence interval [CI], 1.09-1.34). Low performers derived a greater benefit from feedback (RR, 1.62; 95% CI, 1.18-2.23) compared with moderate performers (RR, 1.19; 95% CI, 1.11-1.29), whereas high performers did not derive a significant benefit (RR, 1.06; 95% CI, 0.99-1.13). Feedback was not associated with increases in withdrawal time (weighted mean difference, +0.43 minutes; 95% CI, -0.50 to +1.36 minutes) or improvements in cecal intubation rate (RR, 1.00; 95% CI, 0.99-1.01). CONCLUSION Endoscopist feedback is associated with modest improvements in ADR. The implementation of routine endoscopist audit and feedback should be considered alongside other quality improvement interventions in institutions dedicated to the provision of high-quality screening-related colonoscopy.

Abstract
Colonoscopy is a commonly performed low-risk gastrointestinal procedure that may rarely result in a serious complication. Patients presenting with abdominal pain and fever after colonoscopy may have acute cholecystitis. The underlying mechanisms are unclear. Such patients usually present within 72 hours of the procedure. Treatment includes intravenous antibiotics and cholecystectomy. We present our experience of two such cases; a 56-year-old man and a 21-year-old man, both of whom developed acute calculus cholecystitis within 48 hours after a routine colonoscopy. Their symptoms resolved after cholecystectomy.

Abstract
Colonoscopic polypectomy is a routine procedure with the potential for rare but well-known complications, including perforation and bleeding. Post-polypectomy electrocoagulation syndrome (PPES) is a less recognized cause of abdominal pain following this procedure. However, it is important to diagnose PPES in order to avoid unnecessary intervention. We present the case of a patient with abdominal pain after polypectomy. The patient underwent an unnecessary diagnostic laparoscopy on the basis of misinterpreted radiological findings. Her CT scan demonstrated the "donut" sign that was suggestive of ileocaecal intussusception. This case highlights the importance of recognizing PPES as a possible cause for abdominal pain after colonoscopic polypectomy and that it may also present with a "pseudodonut" sign on CT scan. It also demonstrates the importance of communicating and then integrating full clinical details with radiological findings when formulating a differential diagnosis.
