RESUMEN
BACKGROUND: Double-balloon enteroscopy (DBE) is a standard method for diagnosing and treating small bowel disease. However, DBE may yield false-negative results due to oversight or inexperience. We aim to develop a computer-aided diagnostic (CAD) system for the automatic detection and classification of small bowel abnormalities in DBE. DESIGN AND METHODS: A total of 5201 images were collected from Renmin Hospital of Wuhan University to construct a detection model for localizing lesions during DBE, and 3021 images were collected to construct a classification model for classifying lesions into four classes, protruding lesion, diverticulum, erosion & ulcer and angioectasia. The performance of the two models was evaluated using 1318 normal images and 915 abnormal images and 65 videos from independent patients and then compared with that of 8 endoscopists. The standard answer was the expert consensus. RESULTS: For the image test set, the detection model achieved a sensitivity of 92% (843/915) and an area under the curve (AUC) of 0.947, and the classification model achieved an accuracy of 86%. For the video test set, the accuracy of the system was significantly better than that of the endoscopists (85% vs. 77 ± 6%, p < 0.01). For the video test set, the proposed system was superior to novices and comparable to experts. CONCLUSIONS: We established a real-time CAD system for detecting and classifying small bowel lesions in DBE with favourable performance. ENDOANGEL-DBE has the potential to help endoscopists, especially novices, in clinical practice and may reduce the miss rate of small bowel lesions.

BACKGROUND AND AIM: Balloon endoscopy-assisted endoscopic retrograde cholangiopancreatography (BE-ERCP) is an emerging procedure for pancreatobiliary diseases in patients with surgically altered anatomy. However, data on BE-ERCP for hepatolithiasis after hepaticojejunostomy (HJS) are still limited. METHODS: Stone removal success, adverse events and recurrence were retrospectively studied in consecutive patients who underwent BE-ERCP for hepatolithiasis after HJS between January 2011 and October 2022. Subgroup analysis was performed to compare clinical outcomes between patients who had undergone HJS over 10 years before (past HJS group) and within 10 years (recent HJS group). RESULTS: A total of 131 patients were included; 39% had undergone HJS for malignancy and 32% for congenital biliary dilation. Scope insertion and complete stone removal were successful in 89% and 73%, respectively. Early adverse events were observed in 9.9%. Four patients (3.1%) developed gastrointestinal perforation but could be managed conservatively. Hepatolithiasis recurrence rate was 17%, 20% and 31% in 1-year, 3-year, and 5-year after complete stone removal. The past HJS group was the only risk factor for failed stone removal (odds ratio 10.4, 95% confidence interval 2.99-36.5) in the multivariable analysis. Failed scope insertion (20%) and failed guidewire or device insertion to the bile duct (22%) were two major reasons for failed stone removal in the past HJS group. CONCLUSIONS: BE-ERCP for hepatolithiasis was effective and safe in cases with HJS but the complete stone removal rate was low in the past HJS group. Recurrent hepatolithiasis was common and careful follow up study is needed even after complete stone removal.

BACKGROUND: A GI hospitalist (GIH) is a physician who practices in the inpatient setting performing consultations and endoscopic procedures. Obscure small bowel bleeding is a common inpatient diagnosis that is difficult to manage and associated with longer hospitalizations. Having an onsite GIH physician with expertise in video capsule endoscopy (VCE) and double-balloon enteroscopy (DBE) has the potential to improve patient outcomes. AIMS: This study will be the first to explore how implementing a GIH model and providing a GIH with training in DBE can affect the outcomes of patients with small bowel pathology. METHODS: We performed a retrospective study of patients who received an inpatient DBE at an academic medical center before and after initiation of a GIH model and credentialing of a GIH in DBE. We compared outcomes, including procedure volumes, diagnostic and therapeutic yields, procedure duration, time to procedure, and length of stay. RESULTS: There was a 46.5% increase in the number of DBEs performed by the GIH. The diagnostic yield increased from 56.3 to 74.0% (OR 2.2, 95% CI 1.2-4.2), and the proportion of DBEs with a therapeutic intervention increased from 38.0 to 65.4% (OR 3.1, 95% CI 1.4-7.0). The total procedure time increased from 77.8 to 96.4 min (p < 0.05) with a GIH. CONCLUSION: Having a GIH perform inpatient DBEs was associated with an increased number of procedures, duration of procedures, diagnostic yield, and therapeutic interventions. The onsite presence of a GIH with competency in DBE improves the care of hospitalized patients with small bowel pathology.
RESUMEN
BACKGROUND: To evaluate the long-term efficacy of single-balloon enteroscopy endoscopic retrograde cholangiography (SBE-ERC) for the treatment of biliary obstruction and to analyze the factors affecting the recurrence of benign bilioenteric anastomotic stricture after SBE-ERC treatment. METHODS: The clinical data of patients with biliary diseases treated with SBE-ERC after choledochojejunostomy in our hospital from January 2015 to December 2021 were analyzed retrospectively for the success rates of diagnosis and treatment and the incidence of complications. Patients who were diagnosed with benign bilioenteric anastomotic stricture were followed up. The independent factors affecting recurrence were obtained by univariate and multivariate analyses using the KaplanâMeier method and Cox proportional hazard regression model. RESULTS: A total of 289 SBE-ERCs were performed in 165 patients. The overall success rate was 83.0% (240/289). The incidence of postoperative complications was 5.2% (15/289). The 108 successfully treated patients diagnosed with benign bilioenteric anastomotic stricture were followed up. Twenty-six percent (29/108) of patients had recurrent stricture after SBE-ERC. The biliary patency rates at 1 year, 2 years and 5 years after SBE-ERC were 90.1%, 69.3%, and 53.9%, respectively. Single-factor analysis revealed the absence of intrahepatic biliary gas imaging during endoscopy ( χ 2 =5.366, P = 0.021), a diameter of balloon dilatation during the last endoscopic treatment less than 0.8 cm ( χ 2 =4.552, P = 0.033), and the presence of a thread in the anastomosis ( χ 2 =8.921, P = 0.003) as risk factors for recurrence. A non-indwelling biliary plastic stent ( χ 2 =14.868, P < 0.001) and undergoing only one ERCP treatment ( χ 2 =13.313, P = 0.001) were risk factors for the recurrence of benign stricture after SBE-ERC resection. Multivariate analysis revealed that the absence of a stent (HR = 0.15, 95% CI 0.06-0.40, P = 0.001), absence of intrahepatic biliary gas imaging during endoscopy (HR = 0.39, 95% CI 0.17-0.91, P = 0.03) and the presence of a thread in the anastomosis (HR = 3.69, 95% CI 1.59-8.57, P = 0.002) were independent risk factors for stricture recurrence. CONCLUSIONS: Treating biliary disease after choledochojejunostomy with SBE-ERC is safe and effective, with a good immediate technical success rate and an acceptable incidence of complications. SBE-ERC has long-term efficacy in the treatment of benign bilioenteric anastomotic stricture. The absence of intrahepatic biliary gas imaging during endoscopy, non-indwelling biliary stents and the existence of anastomotic threads are independent risk factors for the recurrence of benign bilioenteric anastomotic stricture.
RESUMEN
BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is a common procedure, but it poses challenges in patients with surgically altered gastrointestinal anatomy (SAGA). Alternative techniques like single-balloon enteroscopy (SBE), double-balloon enteroscopy (DBE), or push enteroscopy (PE) have been used, albeit with potential complications. Limited Latin American data exists on ERCP complications in SAGA patients. Our goal is to describe complications of ERCP in SAGA at a national referral institution. METHODS: Retrospective, single-center cohort study. All SAGA ERCP procedures performed at the Gastrointestinal Endoscopy Department of the National Institute of Medical Sciences and Nutrition Salvador Zubirán from January 2008 to May 2023 were included. Extracted data from records included procedure specifics, endoscope type, success, and complications. Complications were evaluated during procedure and 28-day post-procedure and classified using the AGREE system. RESULTS: A total of 266 procedures in 174 patients were included, 74% were women, and the median age was 44 years. Predominant modified anatomy was Roux-en-Y biliary reconstruction (79%), followed by Whipple procedure (13%) and subtotal gastrectomy with Roux-en-Y reconstruction (6.0%). The main indications were cholangitis with stricture (31%), stricture (19%), and cholangitis (19%). DBE was used in 89%, PE in 7.5%, and SBE in 3.4%. Success rates were 77% endoscopic, 72% technical, and 69% therapeutic; in 30%, the procedure was unsuccessful. Complications happened in 18% of cases, most commonly cholangitis (7.5%), followed by perforation (2.6%) and hemorrhage (1.9%). According to the AGREE classification, 10.9% were grades 1 and 2, 6.4% were grade 3, and 0.4% were grade 4 complications. No significant differences emerged between groups with and without complications. Procedures increased over time, but complications and unsuccessful procedures remained stable. CONCLUSION: ERCP complications align with international data, often not requiring invasive treatment. Enhanced exposure to such cases correlates with fewer complications and failures. Prospective studies are essential to identify complication and failure predictors.

BACKGROUND: Small bowel capsule endoscopy (SBCE) and device-assisted enteroscopy (DAE) have an established role in the investigation and management of small bowel pathology. Previous studies have reported on the yield of SBCE (60%) and DAE (57%), but none have been in an Australian setting. AIMS: To determine the yield of SBCE and any DAE performed as a direct consequence of SBCE in an Australian referral centre. METHODS: A single-centre retrospective study was conducted at a tertiary hospital in Australia, enrolling consecutive patients between 1 January 2009 and 31 December 2021 undergoing SBCE. Data were collected with respect to demographics, procedural factors and findings, as well as findings and interventions of any DAE procedures performed after the SBCE. RESULTS: 1214 SBCEs were performed, with a median age of 66 years old (60.8% men). The predominant indications were anaemia (n = 853, 70.2%) and overt gastrointestinal bleeding (n = 320, 26.4%). Of the complete small bowel studies (1132/1214, 93.2%), abnormal findings were detected in 588 cases (51.9%), most commonly angioectasias (266/588, 45.2%), erosions (106/588, 18.0%) and ulcers (97/588, 8.6%). 165 patients underwent a DAE (117 antegrade, 48 retrograde). Antegrade DAE had a higher yield than retrograde DAE (77.8% vs 54.2%; P = 0.002) and a higher rate of intervention (69.2% vs 37.5%; P < 0.001). CONCLUSION: In this largest single-centre cohort of patients undergoing SBCE to date, there is a similar yield of abnormal findings compared to existing literature. DAE, especially with an antegrade approach, had high diagnostic and therapeutic yield when pursued after a positive SBCE study.

OBJECTIVES: Blue rubber bleb nevus syndrome (BRBNS) is a rare challenging cause of gastrointestinal bleeding. We performed a systematic review of case reports and case series on BRBNS to gather information on the treatment options currently available. METHODS: All studies reporting a case of BRBNS in humans were evaluated. Papers were ruled out if CARE criteria and explanations on patient's selection, ascertainment, causality, and reporting were not respected or identified. PROSPERO 2021 CRD 42021286982. RESULTS: Blue rubber bleb nevus syndrome was treated in 106 cases from 76 reports. 57.5% of the population was under 18 years old, and up to 50% of the cases reported a previous treatment. Clinical success was achieved in 98 patients (92.4%). Three main types of interventions were identified: systemic drug therapy, endoscopy, and surgery. After BRBNS recurrence or previous therapy failure, systemic drug therapy emerged as a preferred second-line treatment over endoscopy (P = 0.01), but with a higher rate of reported adverse events when compared with surgery and endoscopy (P < 0.001). Endoscopic treatment was associated with a higher number of required sessions to achieve complete eradication when compared with surgery (P < 0.001). No differences between the three main areas were found in the overall follow-up time (P = 0.19) or in the recurrence rate (P = 0.45). CONCLUSION: Endoscopy, surgery, and systemic drug therapy are feasible treatment options for BRBNS. Systemic drug therapy was the favorite second-line treatment after endoscopic failure or recurrence of BRBNS, but adverse events were more frequently reported.

OBJECTIVES: Texture and color enhancement imaging (TXI) reportedly improves the identification of the papilla of Vater for selective biliary cannulation compared with white light imaging (WLI). This multicenter study evaluated the efficacy of short-type single-balloon enteroscopy (SBE)-assisted biliary cannulation using a new-generation image-enhanced endoscopy processing system equipped with TXI in patients who underwent Roux-en-Y gastrectomy. METHODS: Patients with Roux-en-Y gastrectomy with a native papilla, and underwent short SBE-assisted biliary cannulation during endoscopic retrograde cholangiopancreatography-related procedures between January 2019 and April 2023 were retrospectively reviewed. Outcomes of biliary cannulation using TXI and WLI were compared. The primary outcome was time to successful biliary cannulation. RESULTS: Thirty-three patients underwent biliary cannulation with TXI and 98 underwent WLI. The biliary cannulation success rates and median time to successful biliary cannulation with TXI and WLI were 93.9% (95% confidence interval [CI] 79.8-99.3%) and 83.7% (95% CI 74.8-90.4%), respectively (P = 0.14), and 10 min (interquartile range [IQR] 2.5-23.5) and 18 min (IQR 9.75-24), respectively (P = 0.04). Biliary cannulation with TXI required a shorter cannulation time than that required with WLI. Adverse event rates with TXI and WLI did not differ significantly (P = 0.58). Multivariate linear regression analysis showed that the use of TXI and short length of oral protrusion were associated with a shorter successful biliary cannulation time. CONCLUSION: Short SBE-assisted biliary cannulation was effective and safe on TXI in patients who underwent Roux-en-Y gastrectomy, and achieved shorter successful biliary cannulation time.
RESUMEN
As management of upper gastrointestinal malignancies improves, and with popularization of bariatric surgery, endoscopists are likely to meet patients with altered upper gastrointestinal anatomy. Short-term, the surgery can cause complications like bleeding, leaks, and fistulas, and longer-term problems such as intestinal or biliary anastomotic strictures or biliary stones can arise, all necessitating endoscopy. In addition, the usual upper gastrointestinal pathologies can also still occur. These patients pose unique challenges. To proceed, understanding the new layout of the upper gastrointestinal tract is essential. The endoscopist, armed with a clear plan for navigation, can readily diagnose and manage most commonly occurring conditions, such as marginal ulcers and proximal anastomotic strictures with standard endoscopic instruments. With complex reconstructions involving long segments of small bowel, such as Roux-en-Y gastric bypass, utilization of balloon-assisted enteroscopy may be necessary, mandating modification of procedures such as endoscopic retrograde cholangiopancreatography. Successful endoscopic management of patients with altered anatomy will require prior planning and preparation to ensure the appropriate equipment, setting, and skill set is provided.
RESUMEN
OBJECTIVES: This study assessed factors influencing the complete removal and recurrence of bile duct stones in patients with surgically altered anatomy (SAA) undergoing double-balloon endoscopy-assisted endoscopic retrograde cholangiography (DBERC). METHODS: A retrospective analysis of 289 patients with SAA treated for biliary stones with DBERC at Jichi Medical University Hospital (January 2007 to December 2022) was conducted. Evaluation of factors impacting complete stone removal was performed in 257 patients with successful bile duct cannulation. Logistic and Cox proportional hazards regression models were used to compute the odds ratios (ORs) and hazard ratios (HRs) at 95% confidence intervals (CIs). RESULTS: Of 257 patients, 139 (54.0%) and 209 (81.3%) achieved initial and complete removal, respectively. Recurrence occurred in 55 (21.4%) patients. Factors associated with initial complete stone removal included cholangitis (P < 0.01, OR 0.48, 95% CI 0.27-0.83), number of stones (P < 0.01, OR 0.31, 95% CI 0.18-0.54), and largest stone diameter (P < 0.01, OR 0.37, 95% CI 0.20-0.67). The size of the largest stone was associated with complete removal (P = 0.01, OR 0.24, 95% CI 0.13-0.76). Recurrence was associated with cholangitis (P = 0.046, HR 0.54, 95% CI 0.29-0.99), congenital biliary dilatation (P = 0.01, HR 2.65, 95% CI 1.21-5.80), and number of stones (P = 0.02, HR 1.96, 95% CI 1.12-3.41). CONCLUSIONS: Successful complete bile stone removal in patients with SAA depends on the stone diameter and number. Stone recurrence is influenced by the number of stones and history of congenital biliary dilatation.
RESUMEN
BACKGROUND: Peutz-Jeghers syndrome (PJS) is an autosomal dominant disorder characterized by hamartomatous gastrointestinal polyps along with the characteristic mucocutaneous freckling. Multiple surgeries for recurrent intussusception in these children may lead to short bowel syndrome. Here we present our experience of management in such patients. METHODS: From January 2015 to December 2023, we reviewed children of PJS, presented with recurrent intussusceptions. Data were collected regarding presentation, management, and follow-up with attention on management dilemma. Diagnosis of PJS was based on criteria laid by World Health Organization (WHO). RESULTS: A total of nine patients were presented with age ranging from 4 to 17 years (median 9 years). A total of eighteen laparotomies were performed (7 outside, 11 at our centre). Among 11 laparotomies done at our centre, resection and anastomosis of bowel was done 3 times while 8 times enterotomy and polypectomy was done after reduction of intussusception. Upper and lower gastrointestinal endoscopy (UGIE & LGIE) was done in all cases while intraoperative enteroscopy (IOE) performed when required. Follow-up ranged from 2 months to 7 years. CONCLUSION: Children with PJS have a high risk of multiple laparotomies due to polyps' complications. Considering the diffuse involvement of the gut, early decision of surgery and extensive bowel resection should not be done. Conservative treatment must be tried under close observation whenever there is surgical dilemma. The treatment should be directed in the form of limited resection or polypectomy after reduction of intussusception.

Crohn's disease (CD) affecting the jejunum and ileum is uncommon and its diagnosis can be challenging. This case report describes a 35 year old male patient who had been e xper iencing intermi ttent periu mbilica l pain , di arrho ea and fever for five years. Despite undergoing gastroscopy, co lo noscopy and capsule endoscopy; no s ignific ant abnormal ities were found. This case was se en at the Shenzhen Ho spital of Traditional Chinese Medi ci ne; Shenzhen, China. However, the pa tient u nder went a doubl e-balloon enteroscopy (DBE), which revealed multip le ulcers in the jejunum and ileum, leadin g to a confirmed diagnosis of CD. The patient was successfully treated with infliximab t o rel ieve sy mptoms. DBE can be par ticularly valuable in diagnosing CD in young patients with symptoms when conventional endoscopic techniques have been unsuccessfu l. This case highlights the impor tance of considering small bowel disease in patients wit h CD symptoms and the potential benefits of DBE in diagnosing such cases.

OBJECTIVE: Recent studies have shown that motorised spiral enteroscopy (MSE) enables deeper and total small bowel evaluation compared with single-balloon enteroscopy (SBE) in suspected Crohn's disease (CD) when analysed per procedure. However, no randomised controlled study has compared bidirectional MSE with bidirectional SBE in suspected CD. DESIGN: Patients with suspected CD requiring small bowel enteroscopy were randomly assigned to either SBE or MSE between May 2022 and September 2022 in a high volume tertiary centre. Bidirectional enteroscopy was done if intended lesion could not be reached on unidirectional study. Comparison was made with regard to technical success (ability to reach lesion), diagnostic yield, depth of maximal insertion (DMI), procedure time and total enteroscopy rates. Depth:time ratio was calculated to avoid confounding for the location of lesion. RESULTS: Among 125 suspected patients with CD (28% female, 18-65 years, median 41 years), 62 and 63 underwent MSE and SBE, respectively. The overall technical success (98.4 %: MSE, 90.5 %: SBE; p=0.11), diagnostic yield (95.2%: MSE; 87.3%: SBE, p=0.2) and procedure time were not significantly different. However, MSE appeared to have higher technical success (96.8% vs 80.7%, p=0.08) in deeper small bowel (distal jejunum/proximal ileum) with higher DMI, higher depth:time ratio and total enteroscopy rates when attempted (77.8% vs 11.1%, p=0.0007). Both the modalities were safe although minor adverse events were more common with MSE. CONCLUSION: MSE and SBE have comparable technical success and diagnostic yield for small bowel evaluation in suspected CD. MSE scores over SBE with regard to deeper small bowel evaluation with complete small bowel coverage and higher depth of insertion in a shorter time. TRIAL REGISTRATION NUMBER: NCT05363930.

INTRODUCTION: Motorized spiral enteroscopy (MSE) is a promising novel deep enteroscopy technique. The purpose of our study was to evaluate efficiency and safety of MSE in a single tertiary endoscopy center. METHODS: We prospectively evaluated all consecutive patients undergoing MSE in our endoscopy unit from June 2019 through June 2022. Main outcomes were technical success rate, proportion of procedures with sufficient depth of insertion, success rate of total enteroscopy, diagnostic yield and complication rate. RESULTS: A total of 82 examinations in 62 patients (56% males, mean age 58 ± 18 years) were performed, 56 from antegrade and 26 from retrograde approach. Technical success rate was 94% (77/82) and in 89% (72/82) of cases, depth of insertion was considered sufficient. Total enteroscopy was indicated in 19 patients and it was achieved in 16 of them (84%), either by antegrade in 4 or by combined approach in 12 cases. Diagnostic yield was 81%. Lesion of the small bowel was found in 43 of patients. Mean insertion time was 40 for antegrade and 44 min for retrograde procedures, respectively. Complications occurred in 3% (2/62) of patients. One patient suffered from mild acute pancreatitis after total enteroscopy and there was one intussusception of the sigmoid during endoscope withdrawal resolved by parallel colonoscope insertion. CONCLUSION: In our series of 82 procedures in 62 patients examined by MSE during a three-year period, we show high technical success rate (94%), diagnostic yield (81%) and low complication rate (3%).
RESUMEN
BACKGROUND: To analyze the diversity in endoscopic manifestations of Meckel's diverticulum (MD) in adults by using balloon-assisted enteroscopy (BAE) and supply more information on the application of BAE. METHODS: A retrospective study was carried out on adult patients diagnosed with MD by BAE in two tertiary general hospitals in China, from May 2007 to September 2021. The patients were divided into a small bowel bleeding (SBB) group and a control group according to their main symptoms. Clinical charts and endoscopic images were reviewed, analyzed, and summarized. RESULTS: Single diverticulum in the ileum and double-lumen sign were observed in all patients. The SBB group consisted of 51 patients, among which 35 cases of ulcerative lesions, 9 cases of erosive lesions, 9 cases of active bleeding/blood clots, and 4 cases of lumps inside the diverticulum were observed respectively. Majority of ulcerative lesions were inside the diverticulum (23/35). A circumferential stricture inside the diverticulum was discovered in 11 cases, and ulcerative lesions tended to occur at this structure (10/11). In the control group consisting of 15 patients, 1 case of erosive lesions at the orifice edge was observed. The percentage of patients with MD-associated ulcerative lesions was significantly higher in the SBB group than that in the control group (p < 0.001). CONCLUSIONS: The endoscopic manifestations of MD in adults are extraordinarily complex and connected with the patients' primary symptoms. The internal features of MD should be regarded as crucial observational objectives in adult patients.

BACKGROUND: Standard endoscopic retrograde cholangiography (ERC) frequently fails to treat biliary obstruction in patients with altered gastrointestinal anatomy. Balloon enteroscopy-assisted ERC (BE-ERC) and combined percutaneous transhepatic endoscopic rendezvous procedures (PTE-RVs) may offer effective rescue approaches. OBJECTIVE: This study aimed to evaluate the efficacy and safety of BE-ERC and PTE-RV for the treatment of biliary obstruction in patients with altered gastrointestinal anatomy. METHODS: In this observational study, all patients with altered gastrointestinal anatomy underwent BE-ERC between 2003 and 2016 at a tertiary referral center. In case of procedural failure, a combined PTE-RV was performed in selected cases. Endpoints included the success and safety of the procedures. RESULTS: A total of 180 BE-ERC performed in 106 patients with altered gastrointestinal anatomy were included. Of the procedures, 76.7% were performed due to benign and 23.3% due to malignant biliary obstruction. BE-ERC was successful in 53% (96/180) of cases. In case of failure, in 23/32 cases a combined PTE-RV was successfully performed, improving the overall success rate of BE-ERC, including PTE-RV, to 66% (119/180). Benign biliary obstruction and repeated procedures were positive predictors of successful BE-ERC (odds ratio 6.8 (95% CI 2.7-17.0), p < .001 and odds ratio 4.1 (2.1-8.2), p < .001). Complications were significantly more frequent in combined PTE-RVs than in BE-ERC procedures alone (34.4% vs. 7.4%; p < .001). CONCLUSIONS: BE-ERC is effective and safe for the endoscopic management of patients with altered gastrointestinal anatomy and percutaneous transhepatic rendezvous procedures can substantially increase success rates in selected cases.

BACKGROUND: There is still no consensus on the preferred endoscopic therapy for small bowel angioectasias (SBAs). The aim of this study was to evaluate effectiveness and safety of endoscopic injection sclerotherapy (EIS) for treating recurrent bleeding of SBAs. METHODS: Sixty-six adult patients diagnosed with SBAs by capsule endoscopy (CE) or double-balloon enterscopy (DBE) examinations were enrolled in this retrospective study from September 2013 to September 2021. The patients were divided into an EIS group (35 cases) and a control group (31 cases) according to whether they underwent EIS treatment. Clinical characteristics, medical histories, lesion characteristics, main laboratory indicators, treatments, and outcomes were collected. The rates of re-bleeding, re-admission, and red blood cell (RBC) transfusion were compared between different groups after discharge. The rates of hospitalization and RBC transfusion were compared between before admission and after discharge in both groups. Odds ratios (ORs) and 95% confidence intervals (CIs) were used in the multivariate logistic regression analysis to assess relative factors for re-bleeding. RESULTS: All the rates of re-bleeding, re-admission and RBC transfusion after discharge in the EIS group were significantly lower than those in the control group (all P < 0.05). The rates of hospitalization and RBC transfusion after discharge were significantly lower than those before admission in the EIS group (both P < 0.05), while those did not reach significant differences in the control group (both P > 0.05). Multivariate logistic regression analysis showed that RBC transfusion before admission (OR, 5.655; 95% CI, 1.007-31.758, P = 0.049) and multiple lesions (≥ 3) (OR, 17.672; 95% CI, 2.246-139.060, P = 0.006) were significant risk factors of re-bleeding, while EIS treatment (OR, 0.037; 95% CI, 0.005-0.260, P < 0.001) was a significant protective factor. No endoscopic adverse events were observed during hospitalization and none of the enrolled patients died within 12 months after discharge. CONCLUSION: EIS treatment had good effectiveness and safety for treating recurrent bleeding of SBAs, which could be considered as one of the first-line endoscopic treatment options for SBAs.

There are limited studies on the endoscopic assessment of disease activity using balloon-assisted enteroscopy (BAE) and its predictive role for long-term outcomes of patients with small bowel Crohn's disease (CD). We sought to investigate the value of BAE as a predictor of long-term outcomes in patients with small-bowel CD. A total of 111 patients with small-bowel CD whose endoscopic disease activity was assessed using BAE based on the small-bowel simple endoscopic score for Crohn's disease (small-bowel SES-CD) at Samsung Medical Center were retrospectively selected from January 2014 to August 2020. The outcome was an evaluation of the risk of surgery according to a small-bowel SES-CD of 0-6 vs. ≥ 7 and endoscopic findings (presence of any ulcer and degree of stricture) using the Cox proportional hazards model. The risk of surgery was significantly increased in patients with a small-bowel SES-CD of ≥ 7 compared to a small-bowel SES-CD of 0-6 [hazard ratio (HR) 6.31; 95% confidence interval (CI) 1.48-26.91; p = 0.013]. In addition, the risk of surgery was significantly increased in patients with stenosis with "cannot be passed" compared to the cases without stenosis (HR 12.34; 95% CI 1.66-91.92; p = 0.014), whereas there was no significance in any ulcer. The present study demonstrated the role of BAE in the endoscopic assessment of disease activity and its predictive value for the risk of surgery in small-bowel CD patients. Further optimization of BAE utilization for the assessment of disease activity is warranted in clinical practice.

BACKGROUND: Motorized spiral enteroscopy (MSE) is a novel advance in small bowel examination that is characterized as fast with a deep insertion. The aim of this study was to elucidate the effectiveness and safety of MSE. METHODS: Relevant articles that were published before November 1, 2022 were identified by searching PubMed, EMBASE, Cochrane, and the Web of Science. The technical success rate (TSR), total (pan)-enteroscopy rate (TER), depth of maximum insertion (DMI), diagnostic yield, and adverse events were extracted and analyzed. Forest plots were graphed based on random effects models. RESULTS: A total of 876 patients from 8 studies were eligible for analysis. The pooled results of the TSR were 95.0% [95% confidence interval (CI) 91.0-98.0%, I2 = 78%, p < 0.01] and the pooled outcome of the TER was 43.1% (95% CI 24.7-62.5%, I2 = 95%, p < 0.01). The pooled results of the diagnostic and therapeutic yields were 77.2% (95% CI 69.0-84.5%, I2 = 84%, p < 0.01) and 49.0% (95% CI 38.0-60.1%, I2 = 89%, p < 0.01), respectively. The pooled estimates of adverse and severe adverse events were 17.2% (95% CI 11.9-23.2%, I2 = 75%, p < 0.01) and 0.7% (95% CI 0.0-2.1%, I2 = 37%, p = 0.13), respectively. CONCLUSION: MSE is a novel alternative approach for small bowel examination that can achieve high TER and diagnostic and therapeutic yields, and relatively low rates of severe adverse events. Head-to-head studies comparing MSE and other device-assisted enteroscopies are warranted.

BACKGROUND AND AIMS: Surgically altered gastrointestinal (GI) tract anatomy hinders deep enteroscopy. While enteroscopy-assisted endoscopic retrograde cholangiopancreatography (ERCP) in patients with altered GI anatomy has been heavily investigated, the role of non-ERCP balloon-assisted enteroscopy (BAE) has yet to be fully elucidated.Please check and confirm the author names and initials are correct. Also, kindly confirm the details in the metadata are correct.I have checked all you asked and have no correction. Thank you. METHODS: A multicenter retrospective study of non-ERCP BAEs in patients with surgically altered GI tract anatomy at two tertiary academic hospitals was performed from January 2006 to December 2020. Altered GI tract anatomy was defined by surgical reconstruction affecting the length, angle, or overall trajectory of the endoscope during the intended approach. The main outcome measurements included technical success rate, diagnostic and therapeutic yields, and complication rate.Please check the edit made in the title of the article and correct if necessary.No more correction. Thank you. RESULTS: A total of 68 patients with surgically altered GI tract anatomy underwent 56 antegrade and 24 retrograde non-ERCP BAE procedures. The technical success rate was 86.2% in both, including 83.9% via antegrade approach and 91.7% via retrograde approach. Antegrade approach in Roux-en-Y anatomy was associated with the lowest success rate of 77.8%, whereas retrograde approach in patients with colon resection resulted in the highest rate of 100%. The diagnostic and therapeutic yields of non-ERCP BAE were 79.4% and 82.9%, respectively. The diagnostic yields varied according to the procedural indications. The major complication was luminal perforation in one case (1.3%). CONCLUSIONS: Non-ERCP BAE is effective and safe via both antegrade and retrograde approaches with a high technical success rate and diagnostic and therapeutic yields in patients with surgically altered GI tract anatomy.
