RESUMO
BACKGROUND: Missed lesions are common during standard colonoscopy and are correlated with post-colonoscopy colorectal cancer. Contrast-enhanced technologies have recently been developed to improve polyp detection. We aimed to evaluate the impact of linked color imaging (LCI) on the proximal adenoma miss rate in routine colonoscopy. METHODS: This national, multicenter, tandem, randomized trial compared the outcomes of colonoscopy with white-light imaging (WLI) versus LCI for polyp detection in the right colon. Two consecutive examinations of the right colon (upstream of the hepatic flexure) were made with WLI and LCI by the same operator. First-pass examination by WLI or LCI was randomized 1:1 after cecal intubation. According to statistical calculations, 10 endoscopy units had to include approximately 700 patients. The primary outcome was proximal adenoma miss rate. Secondary outcomes were the proximal miss rates for sessile serrated lesions (SSL), advanced adenomas, and polyps. RESULTS: 764 patients were included from 1 January 2020 to 22 December 2022, and 686 patients were randomized (345 WLI first vs. 341 LCI first). Both groups were comparable in terms of demographics and indications. The proximal adenoma miss rate was not significantly higher in the WLI-first group (36.7%) vs. the LCI-first group (31.8%) (estimated mean absolute difference: 4.9% [95%CI -5.2% to 15.0%], P = 0.34). There was also no significant difference in miss rates for SSLs, advanced adenomas, and polyps in the proximal colon. CONCLUSIONS: In contrast to previous data, this study does not support the benefit of LCI to the proximal adenoma miss rate in routine colonoscopy.
RESUMO
AIMS: In patients with ulcerative colitis (UC), no biomarker is available to help the physician to choose the most suitable biotherapy. The primary objective of this pilot study was to assess the feasibility of identification of α4ß7- and TNF-expressing cells, to predict the response to vedolizumab using confocal laser endoscopy (CLE). METHODS: Patients with moderate-to-severe UC, naïve of biotherapy, received vedolizumab. Clinical evaluation was performed at each infusion. Endoscopic evaluation was performed before inclusion and at week 22. Fresh colonic biopsies were stained using FITC-labelled vedolizumab and Alexa fluor-labelled adalimumab and ex vivo dual-band CLE images were acquired. Blood samples were collected to measure trough concentrations of vedolizumab and to determine absolute counts of T and B cells subpopulations, NK cells and monocytes. RESULTS: Nineteen patients were enrolled in the study and received at least one dose of vedolizumab. Clinical remission and endoscopic improvement were observed in 58% of whom 5 patients (45%) had an endoscopic subscore of 0. In terms of clinical response and remission, endoscopic improvement and histologic response, FITC-conjugated vedolizumab staining tended to be higher in responder patients compared to non-responders at week 22. A threshold value of 6 positive FITC-vedolizumab staining areas detected by CLE seemed informative to discriminate the responders and non-responders. The results were similar in terms of clinical remission and endoscopic improvement with a sensitivity of 78% and a specificity of 85% (p = 0.05). Trough concentrations and blood immune cells were not associated with responses to vedolizumab. CONCLUSION: This pilot study demonstrate that dual-band CLE is feasible to detect α4ß7- and TNF-expressing cells. Positive α4ß7 staining seems to be associated with clinical and endoscopic remission in UC patients treated by anti-α4ß7-integrin, subject to validation by larger-scale studies.

BACKGROUND & AIMS: The majority of patients with familial adenomatous polyposis (FAP) develop duodenal adenomas with a risk of progression to duodenal cancer. Endoscopic management of FAP duodenal adenomas has been proposed as a less-invasive option than surgery, but available data still are limited. Our aims were to assess the feasibility and safety of endoscopic treatment in duodenal polyposis and to evaluate its long-term efficacy in terms of recurrence and malignant degeneration. METHODS: FAP patients with stage IV duodenal polyposis were enrolled in 5 French centers as part of a national cohort and followed up for a median period of 5.66 years (interquartile range, 6.39 y). Primary outcomes were duodenal surgery-free and cancer-free survival. Two groups of patients were identified according to endoscopic procedures: group 1: resection and or destruction (by argon plasma coagulation) of duodenal polyps, and group 2: papillectomy. RESULTS: Fifty-eight patients were enrolled (29 men; median age, 44 y). Endoscopic therapy was performed in 37 patients in group 1 and in 19 patients in group 2. Duodenal cancer-free and surgery-free survival were 95.8% at 5 years and 92.6% at 10 years. Four patients required surgery and 2 patients developed cancers. In the 58 patients, the calculated Spigelman score decreased from 9.24 points at entry to 6.35 at 5 years and then plateaued. Complications (mostly bleeding and perforation) occurred in 20 patients. CONCLUSIONS: In this long-term cohort follow-up evaluation, endoscopic treatment of patients with severe duodenal polyposis appears relatively safe and effective as an alternative to surgery for the prevention of cancer.

As endoscopic treatment enables en bloc resection of T1 colorectal cancers, the risk of recurrence, often assimilated to the risk of lymph node metastases, must be assessed in order to offer patients an additional treatment if this risk is deemed significant. The curative criteria currently used by most guidelines are depth of invasion <1 mm, well or moderately differentiated tumour, absence of lympho-vascular invasion, absence of significant budding and tumour-free resection margins. However, these factors must be assessed by qualified pathologists, as they are difficult to evaluate. Moreover, the combination of these factors leads to unnecessary surgery in over 80 % of patients whose tumours are classified as high risk. Refinement of current criteria and research into new tumour and immunological markers are needed to better predict the actual risk of our patients.

BACKGROUND AND AIMS: Achalasia can be treated very effectively with peroral endoscopic myotomy (POEM), but factors associated with early failure remain to be determined, especially in European cohorts. METHODS: All consecutive adult patients who underwent a first POEM to treat primary achalasia were included in this multicenter retrospective study. Early failure was defined by an Eckardt score (ES) >3 at 3 months after POEM. When evaluating factors predictive of early failure, 2 cohorts were considered: one consisted of the total population, for whom only basic variables were collected, and the other a cohort built for a case-control study that included matched early-failure and early-success patients (ratio, 1:2). RESULTS: Among 746 patients, the early failure rate was 9.4%. Predictive factors were age ≤45 years (P = .019), achalasia types I and III (P < .001), and the development of a severe adverse event during the procedure (P = .023). In the case-control study, the only additional independent risk factor for early failure was a high pre-POEM ES (P = .001). Only the retrosternal pain subscore was significantly associated with the early failure rate. CONCLUSION: The early failure rate of POEM used to treat primary achalasia is <10%. Younger age, type I/III achalasia, and a high pre-POEM ES were significantly associated with failure.

OBJECTIVES: A new short device for percutaneous endoscopic cholangioscopy was recently developed. However, feasibility and safety has not yet been evaluated. The aim of this study was to assess clinical success, technical success, and adverse events (AEs). METHODS: This observational multicenter retrospective study included all patients who underwent percutaneous cholangioscopy using a short cholangioscope between 2020 and 2022. The clinical success, defined as the complete duct clearance or obtaining at least one cholangioscopy-guided biopsy, was assessed. The histopathological accuracy, technical success, and the AE rate were also evaluated. RESULTS: Fifty-one patients (60 ± 15 years, 45.1% male) were included. The majority of patients had altered anatomy (n = 40, 78.4%), and biliary stones (n = 34, 66.7%) was the commonest indication. The technique was predominantly wire-guided (n = 44, 86.3%) through a percutaneous sheath (n = 36, 70.6%) following a median interval of 8.5 days from percutaneous drainage. Cholangioscopy-guided electrohydraulic lithotripsy was performed in 29 cases (56.9%), combined with a retrieval basket in eight cases (27.6%). The clinical success was 96.6%, requiring a median of one session (range 1-3). Seventeen patients (33.3%) underwent cholangioscopy-guided biopsies. There were four (7.8%) cholangioscopy-related AEs (cholangitis and peritonitis). Overall, the technical success and AE rates were 100% and 19.6%, respectively, in a median follow-up of 7 months. CONCLUSION: Percutaneous endoscopic cholangioscopy with a new short device is effective and safe, requiring a low number of sessions to achieve duct clearance or accurate histopathological diagnosis.
RESUMO
INTRODUCTION: Resection is the cornerstone of curative management for pancreatic ductal adenocarcinoma (PDAC). Hospital surgical volume influence post-operative mortality. Few is known about impact on survival. METHODS: Population included 763 patients resected for PDAC within the 4 French digestive tumor registries between 2000 and 2014. Spline method was used to determine annual surgical volume thresholds influencing survival. A multilevel survival regression model was used to study center effect. RESULTS: Population was divided into three groups: low-volume (LVC) (<41 hepatobiliary/pancreatic procedures/year), medium-volume (MVC) (41-233) and high-volume centers (HVC) (>233). Patients in LVC were older (p = 0.02), had a lower rate of disease-free margins (76.7% vs. 77.2% and 69.5%, p = 0.028) and a higher post-operative mortality than in MVC and HVC (12.5% and 7.5% vs. 2.2%; p = 0.004). Median survival was higher in HVC than in other centers (25 vs. 15.2 months, p < 0.0001). Survival variance attributable to center effect accounted for 3.7% of total variance. In multilevel survival analysis, surgical volume explained the inter-hospital survival heterogeneity (non-significant variance after adding the volume to the model p = 0.3). Patients resected in HVC had a better survival than in LVC (HR 0.64 [0.50-0.82], p < 0.0001). There was no difference between MVC and HVC. CONCLUSION: Regarding center effect, individual characteristics had little impact on survival variability across hospitals. Hospital volume was a major contributor to the center effect. Given the difficulty of centralizing pancreatic surgery, it would be wise to determine which factors would indicate management in a HVC.

OBJECTIVES: Little is known about how to perform the endoscopic ultrasound (EUS)-directed transgastric endoscopic retrograde cholangiopancreatography (ERCP; EDGE) in patients with gastric bypass using lumen-apposing metal stents (LAMS). The aim was to assess the risk factors of anastomosis-related difficult ERCP. METHODS: Observational single-center study. All patients who underwent an EDGE procedure in 2020-2022 following a standardized protocol were included. Risk factors for difficult ERCP, defined as the need of >5 min LAMS dilation or failure to pass a duodenoscope in the second duodenum, were assessed. RESULTS: Forty-five ERCPs were performed in 31 patients (57.4 ± 8.2 years old, 38.7% male). The EUS procedure was done using a wire-guided technique (n = 28, 90.3%) for biliary stones (n = 22, 71%) in most cases. The location of the anastomosis was gastro-gastric (n = 24, 77.4%) and mainly in the middle-excluded stomach (n = 21, 67.7%) with an oblique axis (n = 22, 71%). The ERCP technical success was 96.8%. There were 10 difficult ERCPs (32.3%) due to timing (n = 8), anastomotic dilation (n = 8), or failure to pass (n = 3). By multivariable analysis adjusted by two-stage procedures, the risk factors for a difficult ERCP were the jejuno-gastric route (85.7% vs. 16.7%; odds ratio [ORa ] 31.875; 95% confidence interval [CI] 1.649-616.155; P = 0.022), and the anastomosis to the proximal/distal excluded stomach (70% vs. 14.3%; ORa 22.667; 95% CI 1.676-306.570; P = 0.019). There was only one complication (3.2%) and one persistent gastro-gastric fistula (3.2%) in a median follow-up of 4 months (2-18 months), with no weight regain (P = 0.465). CONCLUSIONS: The jejunogastric route and the anastomosis with the proximal/distal excluded stomach during the EDGE procedure increase the difficulty of ERCP.

BACKGROUND: Increasing evidence suggests the beneficial effects of probiotics in irritable bowel syndrome (IBS), but little is known about how they can impact the gut microbiota. Our objective was to evaluate the effects of a multistrain probiotic on IBS symptoms, gut permeability and gut microbiota in patients with diarrhoea-predominant IBS (IBS-D). METHODS: Adults with IBS-D were enrolled in an open-label trial to receive a multistrain probiotic for 4 weeks. Abdominal pain, stool frequency, quality of life, gut permeability, and the luminal and adherent microbiota from colonic biopsies were evaluated before and after supplementation. RESULTS: Probiotics significantly improved symptoms and quality of life, despite having no impact on permeability in the global population. In the population stratified by the response, the diarrhoea responders displayed reduced colonic permeability after supplementation. The luminal and adherent microbiota were specifically altered depending on the patients' clinical responses regarding pain and diarrhoea. Interestingly, we identified a microbial signature in IBS-D patients that could predict a response or lack of response to supplementation. CONCLUSIONS: The multistrain probiotic improved the symptoms of IBS-D patients and induced distinct effects on the gut microbiota according to the patient's clinical response and initial microbiota composition. Our study further supports the need to develop individualised probiotic-based approaches regarding IBS.
RESUMO
BACKGROUND: Colorectal cancer (CRC) screening using fecal immunochemical testing (FIT) aims to detect pre-symptomatic colorectal lesions and reduce CRC mortality. AIMS: The objectives of this study were to determine the FIT sensitivity for diagnosis of CRC, the impact of diagnostic circumstances on treatment and survival, and risk factors for interval cancer (IC). METHODS: This population-based study evaluated the 2016-2017 CRC screening campaign in Finistère, France. CRCs were classified according to diagnostic circumstances: screen-detected CRC (SD-CRC), CRC with delayed diagnosis, IC after negative FIT (FIT-IC), post-colonoscopy CRC, CRC in non-responders and CRC in the excluded population. RESULTS: This study included 909 CRCs: 248 SD-CRCs (6% of positive FIT) and 60 FIT-ICs (0.07% of negative FIT). The FIT sensitivity for CRC was 80.5% (CI95%: 76.1-84.9) at the threshold of 30 µg hemoglobin/g feces used in France. In multivariate analysis, proximal (OR:6.73) and rectal locations (OR:7.52) were associated with being diagnosed with FIT-IC rather than SD-CRC. The FIT positivity threshold maximizing the sum of sensitivity and specificity was found to be 17 µg/g, with 14 additional CRCs diagnosed compared to the current threshold. CONCLUSIONS: Our study confirms the good sensitivity of FIT. A decrease of the FIT detection threshold could optimize sensitivity.

BACKGROUND: Whether Peroral Endoscopic Myotomy (POEM) can be proposed as a second-line treatment in patients with achalasia remains to be confirmed in real-life series. OBJECTIVE: This study aimed to compare the efficacy, feasibility and safety of POEM between treatment-naïve patients and patients who had prior endoscopic or surgical therapies for achalasia. METHODS: All consecutive patients who underwent a POEM procedure for achalasia in our centre from June 2015 to September 2018 were included in this retrospective study. They were classified into treatment-naïve patients (POEM1) and patients who had at least one previous endoscopic and/or surgical treatment for achalasia (POEM2). RESULTS: A total of 105 patients were included, 52 in the POEM1 group and 53 in the POEM2 group. Clinical success (defined as an Eckardt score ≤ 3) at 6 months was observed in 93% of POEM1 patients and 84% of POEM2 patients (p = 0.18). Technical success rate was not significantly different between the two groups (100% vs 96%, respectively; p = 0.50). No significant difference was noted in terms of adverse event rate (19% vs 19%, respectively; p = 1.00). Post-procedure pain occurred in 12% of treatment-naive and 9% of non-naïve patients (p = 0.76). The median length of hospital stay was 3 days in both groups (p = 0.17). Symptomatic gastroesophageal reflux occurred in 25% of POEM1 patients and 16% of POEM2 patients (p = 0.24). CONCLUSION: Efficacy, feasibility and safety of POEM are not different between treatment-naïve and non-naïve patients. POEM is a valuable second-line approach in patients with persistent symptoms of achalasia after surgical or endoscopic treatments.

Pancreatic cancer is associated with high mortality rates, and most cases are diagnosed at advanced stages. This study aimed to evaluate the prognostic factors for survival in pancreatic adenocarcinoma. Data from the Finistere registry of digestive database were used in this analysis. This retrospective population-based study included 2117 patients with pancreatic adenocarcinoma diagnosed between 2005 and 2019. Cox regression was used to assess the impact of different prognostic factors. The overall median age was 74 (IQR 65.0−81.0). The majority of pancreatic adenocarcinoma 1120 (52.90%) occurred in the head of the pancreas. The type of surgical resection correlated with age (pancreaticoduodenectomy performed in 13.39% of patients aged under 65 years and only 1.49% of patients aged ≥ 80 years). For the entire cohort, 1-year mortality rate after diagnosis was 77.81%. Chemotherapy was associated with better survival for both operated (HR 0.17 95% CI 0.22; 0.64 p < 0.001) and unoperated patients (HR 0.41 95% CI 0.27; 0.61 p < 0.001). Palliative radiotherapy was associated with improved survival (HR 0.69 95% CI 0.56; 0.85 p < 0.001). Among operated patients, the presence of lung metastases (median 34.06; CI 20.06; 34.66) was associated with better survival compared with liver metastases (median 21.10; CI 18.10; 28.96), peritoneal carcinomatosis (median 11.00; CI 8.53; 14.63), or distant metastases (median 15.16; CI 12.66; 18.13) (p = 0.0001). Age, curative surgery, positive lymph nodes, chemotherapy, and palliative radiotherapy were corelated with overall survival. Surgical resection is the only potentially curative treatment, but less than a quarter of patients were eligible.
RESUMO
The recent development of per oral endoscopic myotomy (POEM) has been a game changer in the management of patients with achalasia. However, approximately 1 in 10 patients will not experience clinical success. The aim of this mini-review is to describe the current state of knowledge about the risk factors associated with POEM failure for the treatment of achalasia. Suspected risk factors are detailed into pre-, intra-, and post-procedural factors and put into perspective. Pre-procedural factors have been described, such as pre-treatment Eckardt score, previous treatments for achalasia, sigmoid type esophagus, significant esophageal dilatation, non-type II achalasia, young age and long duration of symptoms. An intra-procedural factor, mucosal injury during POEM, has also been associated with POEM failure. The occurrence of post-POEM GERD was identified as a controversial post-procedural factor associated with failure. The presumed mechanisms of POEM failure are incomplete myotomy or ineffective LES disruption, as confirmed by high-resolution manometry. However, when manometry confirms a significant decrease in LES pressure, it is likely that either impaired peristalsis or a morphologic abnormality such as extreme esophageal dilatation or severe tortuosity, which are not treated by POEM, should be suspected. Notably, a recently described adverse effect of POEM is the formation of a pseudo-diverticulum at the site of the myotomy (blown out myotomy). We finally stress the importance of performing a complete workup in case of POEM failure as different mechanisms of POEM failure should lead to different management.
RESUMO
BACKGROUND: Recent guidelines advocate a step-up approach for managing suspected infected pancreatic necrosis (IPN) during acute pancreatitis. Nearly half the patients require secondary necrosectomy after catheter drainage. Our primary objective was to assess the external validity of a previously reported nomogram for catheter drainage, based on four predictors of failure. Our secondary objectives were to identify other potential predictors of catheter-drainage failure. We retrospectively studied consecutive patients admitted to the intensive care units (ICUs) of three university hospitals in France between 2012 and 2016, for severe acute pancreatitis with suspected IPN requiring catheter drainage. We assessed drainage success and failure rates in 72 patients, with success defined as survival without subsequent necrosectomy and failure as death and/or subsequent necrosectomy required by inadequate improvement. We plotted the receiver operating characteristics (ROC) curve for the nomogram and computed the area under the curve (AUROC). RESULTS: Catheter drainage alone was successful in 32 (44.4%) patients. The nomogram predicted catheter-drainage failure with an AUROC of 0.71. By multivariate analysis, catheter-drainage failure was independently associated with a higher body mass index [odds ratio (OR), 1.12; 95% confidence interval (95% CI), 1.00-1.24; P = 0.048], heterogeneous collection (OR, 16.7; 95% CI, 1.83-152.46; P = 0.01), and respiratory failure onset within 24 h before catheter drainage (OR, 18.34; 95% CI, 2.18-154.3; P = 0.007). CONCLUSION: Over half the patients required necrosectomy after failed catheter drainage. Newly identified predictors of catheter-drainage failure were heterogeneous collection and respiratory failure. Adding these predictors to the nomogram might help to identify patients at high risk of catheter-drainage failure. CLINICALTRIALS: gov number: NCT03234166.
RESUMO
BACKGROUND: Survival of patients with colon cancer has increased in recent years due to advances in treatment and the implementation of multidisciplinary team meetings (MDTm). However, the organization of MDTm can be improved. The objectives of this work were to characterize patients with colon cancer who were not presented in MDTm and to analyse the reasons for their non-presentation. METHODS: The study was based on a retrospective cohort including patients with colon cancer diagnosed between 2014 and 2016. Risk factors for non-presentation in MDTm were investigated after 1:1 matching on age, gender and tumour location, using multivariate analysis. RESULTS: amongst 1616 patients diagnosed with colon cancer, 20.5% were not presented in MDTm. The most common reasons for non-presentation were 'advanced age or poor general condition' (22.6%) and 'superficial tumour' (20.5%), while 20.8% of non-presentation remained unexplained. Non-presentation in MDTm was associated with ECOG PS of 2 (OR 0.51, 95%CI 0.32-0.81, p = 0.005), best supportive care (OR 0.05, 95%CI 0.00-0.38, p = 0.016) and early death (OR 0.09, 95%CI 0.04-0.19, p<0.001). By contrast, patients with symptomatic tumours were more likely to be presented in MDTm than patients participating in mass screening (OR 2.16, 95%CI 1.09-4.32, p = 0.028). Presentation was significantly associated with diagnosis by a digestive surgeon (OR 2.16, 95%CI 1.22-3.92, p = 0.01) and a high UICC stage. CONCLUSIONS: This study identified factors associated with non-presentation in a multidisciplinary team meeting for colon cancer such as an advanced age or a superficial tumour, paving the way for targeted improvements.

BACKGROUND: Recurrent sigmoid volvulus is frequent and sometimes occurs in frail patients with contraindications to surgical sigmoidectomy. Percutaneous endoscopic sigmoidopexy (PES) has recently been proposed as an alternative to elective sigmoidectomy. We aimed to describe the efficacy and safety of PES. METHODS: All consecutive patients who underwent PES for recurrent sigmoid volvulus at two French centers between January 2017 and March 2021 were included in this retrospective case series. Recurrent sigmoid volvulus was defined as at least two symptomatic episodes treated by endoscopic decompression. Under endoscopic guidance, anchors were placed to attach the sigmoid to the anterior abdominal wall, allowing the placement of pigtail Chait catheters. RESULTS: 15 patients (60â% female; median age 74 years [range 49-96]) were included. Median number of previous sigmoid volvulus episodes was 3 (range 2-6). Procedures were technically successful with no intraprocedural adverse events for 14 patients (93â%). Peritonitis occurred at Day 2 in one patient (serious adverse event rate 7â%). Median follow-up time was 10 months (range 1-30). No sigmoid volvulus recurrence occurred during follow-up. CONCLUSION: PES using Chait catheters was feasible and effective for recurrent sigmoid volvulus and should be considered as an alternative to sigmoidectomy in inoperable patients.

Background: Endoscopic papillectomy is a minimally invasive treatment for benign tumors of the ampulla of Vater or early ampullary carcinoma. However, reported recurrence rates are significant and risk factors for recurrence are unclear. Objective: The aims of this study were to evaluate the efficacy and safety of endoscopic papillectomy and to identify risk factors for recurrence and adverse events. Methods: All patients who underwent endoscopic papillectomy at five tertiary referral centers between January 2008 and December 2018 were included. Recurrence was defined as the detection of residue on one of the follow-up endoscopies. Treatment success was defined as the absence of tumor residue on the last follow-up endoscopy. Results: A total of 227 patients were included. The resections were en bloc in 64.8% of cases. The mean lesion size was 20 mm (range: 3-80) with lateral extension in 23.3% of cases. R0 resection was achieved in 45.3% of cases. The recurrence rate was 30.6%, and 60.7% of recurrences were successfully treated with additional endoscopic treatment. Finally, treatment success was achieved in 82.8% of patients with a median follow-up time of 22.3 months. R1 resection, intraductal invasion, and tumor size > 2 cm were associated with local recurrence. Adverse events occurred in 36.6% of patients and included pancreatitis (17.6%), post-procedural hemorrhage (11.0%), perforation (5.2%), and biliary stenosis (2.6%). The mortality rate was 0.9%. Conclusion: Endoscopic papillectomy is an effective and relatively well-tolerated treatment for localized ampullary tumors. In this series, R1 resection, intraductal invasion, and lesion size > 2 cm were associated with local recurrence.
RESUMO
BACKGROUND: Little is known about small bowel capsule endoscopy (SBCE) outcomes in patients with surgically altered anatomy. AIMS: To assess the feasibility and diagnostic yield of orally ingested SBCE to investigate obscure gastrointestinal bleeding (OGIB) in patients with surgically altered gastric anatomy, compared to native gastric anatomy. METHODS: 207 patients with OGIB were selected from an open, multicenter, retrospective cohort (SAGA study) and match-paired according to age, gender and bleeding type (overt/occult) to 207 control patients from a randomized controlled trial (PREPINTEST). Primary outcomes were the diagnostic yield (P1 or P2 findings), completion rate, adverse events rate, and small bowel transit time (SBTT). RESULTS: The diagnostic yield was not statistically different between groups (44.9% in SAGA vs 42.5% in control patients). Inflammatory/ulcerated lesions were significantly more frequent in patients with SAGA (43.0% vs 29.3%). The median SBTT was significantly longer in the SAGA group than in control patients (283 vs 206 minutes), with a significantly lower completion rate (82.6% vs 89.9%); Adverse events were scarce (0.5% vs 0.0%). CONCLUSION: Patients with surgically altered gastric anatomy should benefit from SBCE investigation for OGIB as much as non-operated patients.

INTRODUCTION: The aim of our study was to compare clear liquid diet with 2 different polyethylene glycol (PEG)-based bowel preparation methods regarding diagnostic yield of small bowel capsule endoscopy (SBCE) in patients with suspected small bowel bleeding (SBB). METHODS: In this prospective multicenter randomized controlled trial, consecutive patients undergoing SBCE for suspected SBB between September 2010 and February 2016 were considered. Patients were randomly assigned to standard regimen, that is, clear fluids only (prep 1), standard regimen plus 500 mL PEG after SBCE ingestion (prep 2), or standard regimen plus 2 L PEG plus 500 mL PEG after SBCE ingestion (prep 3). The primary outcome was the detection of at least one clinically significant lesion in the small bowel. The quality of small bowel cleansing was assessed. A questionnaire on the clinical tolerance was filled by the patients. RESULTS: We analyzed 834 patients. No significant difference was observed for detection of P1 or P2 small bowel lesions between prep1 group (40.5%), prep 2 group (40.2%), and prep 3 group (38.5%). Small bowel cleansing was improved in prep 2 and 3 groups compared with that in prep 1 group. Compliance to the preparation and tolerance was better in prep 2 group than in prep 3 group. DISCUSSION: Small bowel purgative before SBCE allowed better quality of cleansing. However, it did not improve diagnostic yield of SBCE for suspected SBB.
