Abstract
Objective CT enterography/enteroclysis (CTE) is listed in the clinical practice guidelines as a method for diagnosing small bowel bleeding, as is capsule endoscopy (CE), but there are no real-world data yet available on CTE in Japan. This study aimed to investigate the diagnostic ability of CTE and long-term prognosis after CTE in Japan. Patients We conducted a retrospective cohort study of patients suspected of having small bowel bleeding who underwent both CTE and CE within 30 days between April 2008 and March 2019. The number of patients free from rebleeding for up to 24 months was thus determined. Results Seventy-one patients were extracted from the database. The 43 patients (60.6%) with a definite and suspicious source of bleeding in the small bowel were detected by CTE. When the 31 patients with a definite source of bleeding in the small bowel were analyzed, the sensitivity of CTE was 19/31 (61.3%) and that of CE was 24/31 (77.4%), thus indicating no significant difference (p=0.332). However, the sensitivity when CTE and CE were used in combination was 30/31 (96.8%), which was significantly higher than that of CE alone (p=0.0412). No rebleeding was observed in the CTE and CE negative group (p=0.0965). Conclusion The combined use of CTE and CE increased the detection rate of small bowel bleeding. Therefore, in patients with suspected tumor/polyp lesions, not only CE, but also CTE should be performed. This study provides the first real-world data on the diagnostic accuracy of CTE for small bowel bleeding in Japan.

Abstract
BACKGROUND Small bowel lesions of Crohn's disease (CD) are known to be associated with a poor prognosis; however, endoscopic healing leads to favorable patients' outcome. The aim of this study was to clarify the clinical impact of assessing deep small bowel lesions (DSB) using balloon-assisted enteroscopy (BAE) on CD patients in clinical remission. METHODS From January 2012 to July 2018, a total of 100 CD patients in clinical remission were enrolled to undergo trans-anal enteroscopy using single-balloon enteroscope. Endoscopic evaluations at the terminal ileum (TI) were performed using a partial Simple Endoscopic Score for CD (pSES-CD). Endoscopic evaluations at the DSB used a modified partial SES-CD (mpSES-CD). We evaluated the factors associated with relapse, and the correlation of endoscopic score between the TI and DSB. For this study, relapse was defined as hospitalization within a year from enteroscopy. RESULTS 30 patients (30.0%) relapsed within a year from enteroscopy. Multivariate logistic regression analysis revealed that the Harvey-Bradshaw Index (OR 1.77, 95% CI 1.18-2.65; p = 0.003) and an mpSES-CD at DSB (OR 3.10, 95% CI 1.86-5.15; p = 0.001) were independent predictors for relapse, whereas a SES-CD at the TI did not exhibit independence. There was a significant correlation trend between the relapse rate and greater than 5 points of an mpSES-CD at DSB; however, there was no correlation between the relapse rate and pSES-CD at the TI. CONCLUSION Even when Crohn's disease is in remission, it is important to evaluate DSB using BAE to assess endoscopic mucosal healing.

Abstract
Objective Evaluate impact of balloon-assisted deep small bowel enteroscopy on red blood cell transfusion requirement in patients with obscure gastrointestinal (GI) bleeding.
Methods Retrospective study of patients, who underwent balloon-assisted deep enteroscopy with double-balloon enteroscopy (DBE) at two tertiary care academic centers (University of Wisconsin and Aurora St. Luke’s Medical Center) over a 55-month consecutive period. Sixty-nine patients with reliable blood transfusion records were identified during this time period. DBE was preceded by small bowel capsule endoscopy (CE) within 1 year in 38 cases. Transfusion requirements 6 months prior and postintervention were measured to see if DBE had any impact on the need for blood transfusions.
Results Sixty-nine patients (25 females and 44 males) were included. Mean age ± standard deviation (SD) was 63 ± 17 years. Wilcoxon signed rank test statistics were used to find the difference in the rate of blood transfusion. There was a statistically significant decrease in rate of packed red blood cell (pRBC) transfusion post DBE and endoscopic therapy with coagulation (p < 0.001). Argon plasma coagulation was used to ablate all arteriovenous malformations (AVMs) except in one (subepithelial lesion). Those that required > 5 units pRBC transfusions pre-DBE had the most benefit.
Conclusions Our study demonstrates that transfusion requirements are significantly reduced in those undergoing therapy with DBE and coagulation for obscure GI bleed.

Abstract
BACKGROUND Device-assisted enteroscopy including single-balloon enteroscopy (SBE) allows direct visualization of the small bowel and has good safety and efficacy in experienced hands. Our study is aimed to share our single-centre experience of SBE in diagnosing and treating small-bowel disorders. METHODS We reviewed the prospectively collected data (from December 2016 to December 2019) of 180 consecutive anterograde and/or retrograde procedures. Analysis of baseline characteristics, endoscopic findings, and diagnostic and therapeutic rates was done. RESULTS SBE was done in 158 patients with a median age of 55 years (range, 13-94 years) for suspected small-bowel lesions. Dual enteroscopy (anterograde plus retrograde) was done in 22 patients (13.92%). The indication for the procedure was obscure gastrointestinal bleeding in 129 (71.66%), chronic unexplained abdominal pain in 20 (11.11%), suspected small-bowel abnormality in the form of narrowing and/or mass on imaging in 10 (5.5%), chronic diarrhea in 9 (5%), unexplained iron deficiency anemia in 9 (5%), and retained capsule in 2 (1.11%). The most common finding was ulcer, which was noted in 45 (25%) patients followed by stricture in 8 (4.44%) and both ulcers and strictures in 6 (3.33%) patients. SBE was normal in 61 (33.88%) patients. SBE gave a diagnosis in 66.11% while in 28.43% cases, therapeutic intervention was done. Minor complications like bleeding were noted in 3 patients and mild acute pancreatitis in 2 patients. Jejunal perforation requiring surgical intervention was noted in 1 patient. CONCLUSION SBE is a safe and effective procedure in diagnosing and treating small-bowel diseases.

Abstract
BACKGROUND AND AIMS The small bowel has, to date, remained a difficult area to access via endoscopy. The novel motorized power spiral enteroscopy, recently introduced, has more depth of insertion and is of shorter duration. Presented here is a case series of motorized spiral enteroscopies. METHODS Motorized spiral enteroscopy is indicated for patients requiring deep enteroscopy (eg, for a diagnosis of obscure GI bleeding, suspected inflammatory bowel disorder) and for therapeutic interventions, such as polypectomy, hemostasis, or stricture dilatation. It is contraindicated in patients who are not eligible for general anesthesia, with perforation, or with coagulopathy and in the pediatric population. The contraindications for the anterograde route are gastroesophageal varices, foregut stenosis, eosinophilic esophagitis, and so on. The retrograde approach is contraindicated in active colitis, anal stenosis, or colonic stricture. Informed consent was sought from all the patients. RESULTS The procedure was successful in 13 of 14 (92.8%) in that the target site was reached or panenteroscopy was confirmed. The diagnoses were stricture and ulcers of the jejunum or ileum. The procedures performed were argon plasma coagulation and stricture dilation. The average duration of anterograde enteroscopy was 61.1 minutes and retrograde enteroscopy was 90 minutes. The major adverse events were hypothermia (3 of 14) and pancreatitis (1 of 14), from which the patients recovered fully. CONCLUSIONS Novel motorized power spiral enteroscopy is a great tool in small-bowel diagnostics and therapeutics. Speed and ease add to the attractiveness of the procedure.

Abstract
BACKGROUND Retrograde single balloon enteroscopy (SBE) is a minimally invasive procedure which is less frequently performed compared with antegrade SBE. There are few studies on the retrograde through-the-scope enteroscopy (TTSE), a novel technique for evaluation of the small bowel. AIM To compare the clinical utility and safety of retrograde TTSE with retrograde SBE. METHODS Clinical data and complications of retrograde TTSE (2014-2018) and retrograde SBE (2011-2018) performed in a community hospital were reviewed and presented as mean ± SD or frequency (%) and compared using proper statistical tests. Technical success was defined as insertion of the enteroscope > 20 cm beyond ileocecal valve. RESULTS Data obtained from 54 retrograde SBE in 49 patients and 27 retrograde TTSE in 26 patients were studied. The most common indication for retrograde enteroscopy was iron deficiency anemia (41 patients) followed by gastrointestinal bleeding (37 patients), and chronic diarrhea (7 patients). The duration of retrograde SBE procedure (91.9 ± 34.2 min) was significantly longer compared with retrograde TTSE (70.5 ± 30.7 min) (P = 0.04). Technical success was comparable in TTSE [23/27 (85.2%)] and SBE [41/54 (75.9%) (P = 0.33)]. The mean depth of insertion beyond the ileocecal valve in retrograde SBE (92.5 ± 70.0 cm) tended to be longer compared with retrograde TTSE (64.6 ± 49.0 cm) (P = 0.08). No complication was observed in this study. CONCLUSION Both retrograde TTSE and retrograde SBE are feasible and safe. Retrograde TTSE takes a shorter time and has a comparable technical success with SBE. TTSE has a lower capacity of small bowel insertion.

Abstract
Objective To evaluate the clinical efficacy of double-balloon endoscopy (DBE) for small bowel disease (SBD). Methods The clinical and endoscopic data of patients who underwent DBE in a Chinese tertiary hospital from January 2006 to December 2019 were retrospectively reviewed. The patients were divided into three groups by age: the young group (<45 years), middle-aged group (45–65 years), and older group (>65 years). Results In total, 1177 patients who underwent 2134 DBE procedures were included. The anterograde and retrograde route was used in 1111 and 1023 procedures, respectively. The most common reason for performing DBE was suspected small bowel bleeding (SSBB) (53.1%), and the most common SBD was Crohn's disease (CD) (18.1%). Hemostasis was the predominant endoscopic therapy (54.3%). The total complication rate was 0.8%. The incidence of CD was highest in the young group, and the incidence of tumors was highest in the older group; these findings were consistent both among the overall patient population and among patients with SSBB. Conclusions DBE is effective and safe for the diagnosis and treatment of SBD and is considered to have great potential as a first-line method for diagnosing SBD.

Abstract
BACKGROUND Evidence for endoscopic balloon dilation of small intestinal strictures in Crohn's disease (CD) using balloon-assisted enteroscopy is scarce. AIM To evaluate endoscopic balloon dilation for the treatment of small intestinal CD strictures using balloon-assisted enteroscopy. METHODS Citations in Embase, MEDLINE, and Cochrane were systematically reviewed. In a meta-analysis of 18 studies with 463 patients and 1189 endoscopic balloon dilations, technical success was defined as the ability to dilate a stricture. Individual data were also obtained on 218 patients to identify outcome-relevant risk factors. RESULTS In the pooled per-study analysis, technical success rate of endoscopic balloon dilation was 94.9%, resulting in short-term clinical efficacy in 82.3% of patients. Major complications occurred in 5.3% of patients. During follow-up, 48.3% of patients reported symptom recurrence, 38.8% were re-dilated and 27.4% proceeded to surgery. On the per-patient-based multivariable analysis, that patients with disease activity in the small intestine had lower short-term clinical efficacy (odds ratio 0.32; 95% confidence interval 0.14-0.73, P = 0.007). Patients with concomitant active disease in the small and/or large intestine had an increased risk to proceed toward surgery (hazard ratio 1.85; 95% confidence interval 1.09-3.13, P = 0.02 and hazard ratio 1.77; 95% confidence interval 1.34-2.34, P < 0.001). CONCLUSIONS Balloon-assisted enteroscopy for dilatation of CD-associated small intestinal strictures has high short-term technical and clinical efficacy and low complication rates. However, up to two-thirds of patients need re-dilation or surgery.

Abstract
BACKGROUND AND AIMS The diagnostic yield (DY) and therapeutic yield (TY) of balloon-assisted enteroscopy (BAE) in overt obscure gastrointestinal bleeding (OGIB) is higher in the first 72 h. This study aimed to evaluate if this higher DY and TY after urgent BAE impacted the rebleeding rate, time to rebleed and short-term mortality. METHODS Retrospective cohort-study, which consecutively included all patients submitted to BAE for overt OGIB, between 2010 and 2019. Patients were distributed in 2 groups: (1) Urgent BAE; (2) Non-urgent BAE. Rebleeding was defined as an Hb drop >2 g/dL, need for transfusional support or presence of melena/hematochezia. RESULTS Fifty-four patients were included, of which 17 (31.5%) were submitted to BAE in the first 72 h. DY and TY of urgent BAE (DY 88.2%; n = 15; TY 94.1%; n = 16) was higher compared to non-urgent BAE (DY 59.5%; n = 22; TY 45.9%; n = 17) (DY p = .03) (TY p = .001). The rebleeding rate at 1, 2, and 5 years was 32.0%, 34.0%and 37.0%, respectively. Rebleeding was lower after urgent BAE (17.6%; n = 3) compared to non-urgent BAE (45.9%; n = 17) (p = .04). Rebleeding tended to occurr earlier in non-urgent BAE, being at 6-months (32.5%) and 36 months (41.3%) (p = .05). OGIB related 30-day mortality was 5.4% (n = 2) for non-urgent BAE and 0% for urgent BAE (p = .5). CONCLUSION Urgent BAE might be associated with higher DY and TY with lower rebleeding and trend toward higher rebleeding-free time.

Balloon-Assisted Colonoscopy after Incomplete Conventional Colonoscopy-Experience from Two European Centres with A Comprehensive Review of the Literature. J Clin Med 2020; 9:jcm9092981. [PMID: 32942749 PMCID: PMC7564861 DOI: 10.3390/jcm9092981] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2020] [Revised: 09/03/2020] [Accepted: 09/11/2020] [Indexed: 12/22/2022] Open
Abstract
Background: Conventional colonoscopy (CC) allows access for colonic investigation and intervention; in the small group in whom CC is unsuccessful alternative imaging is often sufficient. There remains a subset, however, requiring full colonic visualisation or intervention. Balloon-assisted colonoscopy (BAC) gives a further option when access is difficult. Aims: This study aims to present the experience with BAC of two European tertiary referral centres. Methods: Procedures were carried out under local protocol over 15-years (2006–2020). Markers of procedural quality such as caecal intubation, complications and comfort were retrospectively compiled and analysed. Published evidence was summarised for comparison. Results: 122 procedures were undertaken, with polyps the most frequent indication and 90.2% having at least one previously incomplete CC. Features associated with difficult colonoscopy were common, including intraabdominal surgery (32.0%). 92.6% reached the caecum; completion was higher (96.3%) in those failing CC due to discomfort and lower in those failing due to anatomical difficulties (90.7%) or previous surgery (84.6%). Mean time to the caecum was 20.9 minutes and mean midazolam and fentanyl doses were 2.6 mg and 49.9 µg with low discomfort scores. Conclusion(s): Balloon-assisted colonoscopy is successful in >90% of patients, is well-tolerated, and is safe.

Endoscopic ultrasound-guided fine needle aspiration for diagnosing pancreatic mass in patients with surgically altered upper gastrointestinal anatomy. Dig Endosc 2020; 32:967-973. [PMID: 31912558 DOI: 10.1111/den.13625] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/13/2019] [Revised: 12/05/2019] [Accepted: 01/05/2020] [Indexed: 12/24/2022]
Abstract
BACKGROUND AND AIMS Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has been established as a safe and accurate method for diagnosing a pancreatic mass; however, EUS-FNA for patients with surgically altered upper gastrointestinal (UGI) anatomy has not yet been investigated sufficiently. Therefore, the feasibility and safety of EUS-FNA in these patients were retrospectively investigated. METHODS Patients in whom EUS-FNA was performed between March 2008 and April 2017 were retrospectively investigated in terms of EUS-FNA technical success, procedure time, diagnostic accuracies of cytology and histology, and procedure-related adverse events. RESULTS Twenty-five EUS-FNAs were performed for 15 pancreatic body-to-tail and 10 head lesions. All patients underwent EUS-FNA successfully; however, changing of the echoendoscope to a forward-viewing echoendoscope and preplacement of a nasobiliary catheter by balloon-assisted enteroscopy for guidance were needed in one and two cases, respectively. The median procedure time was 26 min (range, 16-70). The diagnostic accuracies were 76%, 84%, and 88% for cytology, histology, and combined use, respectively. Adverse events were not observed. CONCLUSIONS Endoscopic ultrasound-guided FNA is a safe and efficient method for diagnosing a pancreatic mass even in patients with surgically altered UGI anatomy. Nevertheless, some sophisticated techniques are required for pancreatic head lesions if reaching the duodenum after passing through the jejunal limb is required for visualization of the pancreatic mass.

Abstract
BACKGROUND The aim of the present study was to investigate the efficacy and safety of double-balloon enteroscopy (DBE) in postoperative pediatric patients. METHODS This was a retrospective analysis of pediatric patients 18 years and younger referred to Mie University Hospital. Twenty procedures in 11 children occurred postoperatively; 29 children (42 procedures) had not undergone surgery. RESULTS Among postoperative patients, five DBE procedures were performed via the oral route, 12 via the anal route, and three via a stomal route. Among nonoperative patients, 14 DBE procedures were performed via the oral route and 28 via the anal route. Four postoperative patients and two nonoperative patients had difficult pleating via the transanal route because of adhesions or thickening of the intestinal wall resulting from inflammation (P = 0.02). Excluding patients with stenosis, the mean length of endoscopic insertion for transanal procedures was significantly shorter among postoperative patients than among nonoperative patients (73.6 cm vs 160.5 cm, P < 0.01). There were no major complications in either group. CONCLUSIONS Insertion difficulty was encountered in postoperative pediatric patients. However, our findings indicate that DBE is a safe procedure in postoperative pediatric patients.

Abstract
The small bowel had long been considered a dark unapproachable tunnel until the invention of capsule endoscopy and doubleballoon enteroscopy in the 21st century, which revolutionized the diagnosis and management of small bowel diseases, including bleeding. Various imaging modalities such as computed tomographic enterography, angiography, capsule endoscopy, and balloonassisted enteroscopy play vital roles in the diagnosis and management of small bowel bleeding. The choice of modality to use and timing of application differ according to the availability of the modalities, patient’s history, and physician’s experience. Small bowel bleeding is managed using different strategies as exemplified by medical treatment, interventional radiology, endoscopic therapy, or surgical intervention. Balloon-assisted enteroscopy enables endoscopic interventions to control small bowel bleeding, including electrocautery, argon plasma coagulation, clip application, and tattooing as a prelude to surgery. In this article, we clarify the recent approaches to the optimal diagnosis and management of patients with small bowel bleeding.

Abstract
Objective and study aims Patients with left-ventricular assist devices (LVADs) have an increased risk of gastrointestinal bleeding, especially from the small bowel, often necessitating evaluation with balloon-assisted enteroscopy (BAE). Our study aimed to assess the periprocedural safety and utility of BAE for gastrointestinal bleeding in patients with LVADs. Patients and methods This was a multicenter retrospective cohort study of adults with LVADs who underwent BAE between January 2007 to December 2018. Results Thirty-four patients underwent a total of 46 BAEs (9 were single-balloon enteroscopies [SBEs] and 37 were double-balloon enteroscopies [DBEs]). Mean age of patients was 66.4 ± 8.3 years. Patients tolerated anesthesia well, without complications. There were no complications from the BAE itself. One patient required repeat BAE due to a progressive drop in hemoglobin and another patient developed paroxysmal supraventricular tachycardia. One patient died within 72 hours of the procedure due to worsening of LVAD thrombosis. Diagnostic yields were 69.6 % for all procedures, 73.0 % for DBE and 55.6 % for SBE ( P = 0.309). Therapeutic yields were 67.4 % overall: 73.0 % for DBE and 44.4 % for SBE ( P = 0.102). In those that presented with overt gastrointestinal bleeding, DBE had a higher diagnostic yield compared to SBE (84.2 % vs. 42.9 %; P = 0.057) and a significantly higher therapeutic yield (84.2 % vs. 28.6 %; p = 0.014). Conclusions This is the largest multicenter study of patients with LVADs who underwent DBE. BAE appears to be a safe and useful modality for the evaluation of gastrointestinal bleeding in these patients.

Abstract
BACKGROUND AND AIM Endoscopic retrograde cholangiopancreatography (ERCP) using balloon-assisted endoscope such as double-balloon endoscope is even effective for patients with surgically altered anatomy. Yet comprehensive studies on complications of ERCP using balloon-assisted endoscope have not been made. We analyzed the characteristics and the causes of complications of ERCP using double-balloon endoscope (DB-ERCP) procedures and aimed to suggest effective managements. METHODS A total of 1576 procedures of DB-ERCP in 714 patients with surgically altered gastrointestinal anatomy in our hospital were evaluated retrospectively using a statistic analysis. RESULTS The overall complication occurrence rate was 5.8%. By type of complications are perforation 3.2%, mucosal laceration 0.5%, hemorrhage 1.0%, pancreatitis 0.6%, respiratory disorder 0.4%, and others 0.2%. By type of surgical reconstruction methods were Roux-en-Y reconstruction with choledocho-jejunal anastomosis 4.2%, Roux-en-Y reconstruction without choledocho-jejunal anastomosis 6.7%, pancreaticoduodenectomy 4.5%, pylorus preserving pancreaticoduodenectomy 4.2%, Billroth II gastrectomy (B-II) 11.6%, and other reconstruction method (others) 7.4%. The contributing factors calculated by a multivariate analysis were B-II (odds ratio: 1.864, 95% confidence interval: 1.001-3.471, P = 0.050) and the presence of naïve papilla (odds ratio: 3.268, 95% confidence interval: 1.426-7.490, P = 0.005). CONCLUSIONS DB-ERCP is a safe method with a total complication rate of 5.8% that could be considered within an acceptable range. The most common complication was the injury of the digestive tract such as perforation. Affecting risk factors for complications were B-II and the presence of naïve papilla. DB-ERCP procedures should be performed carefully of these factors.

Abstract
Endoscopy is in a period of continuous innovations in terms of image quality, endoscopes, post-processing software and lastly, application of Artificial Intelligence. Therapeutic boundaries have expanded, widening the grey zone between endoscopy and surgery, and increasing endoscopic approaches in clinical scenarios where, until a few years ago, surgery was the only option. New scopes and accessories have made it easier to access critical areas such as the biliary tree and the small bowel intestine. In the field of hepato-pancreato-biliary endoscopy (HPB), it is now possible to directly access the biliary ducts or cystic lesions though dedicated stents and scopes, rather than having to rely only on fluoroscopy and ultrasound, increasing the diagnostic and therapeutic options by applying a three-dimensional approach. This narrative review will give an overview of some of the most relevant emerging fields in luminal and HPB endoscopy, highlighting advantages and main limitations of the techniques, and providing considerations for future development.

Abstract
Objective We investigated the results of biliary cannulation using a short-type single-balloon enteroscope in patients with a native papilla who had previously undergone Roux-en-Y gastrectomy and analyzed the factors associated with successful cannulation. Methods The study subjects consisted of patients with a native papilla who had previously undergone Roux-en-Y gastrectomy and endoscopic retrograde cholangiopancreatography using a short-type single-balloon enteroscope at our institution between September 2011 and July 2019. We carried out a retrospective investigation of the outcomes, including assessing the success rate of biliary cannulation, and analyzed the factors associated with successful cannulation. Results In total, 78 patients underwent biliary cannulation of a native papilla. The success rate of biliary cannulation was 80.8% (88.5% when including success on repeated attempts). The success rate of the standard cannulation technique was 60.3%, with the use of advanced cannulation techniques to secure the pancreatic duct providing the same additional effect as a normal anatomy. Adverse events occurred in 9.0% of cases. A multivariate analysis of the Roux-en-Y gastrectomy patients found that cannulation was more likely to be successful in patients in whom the scope could be placed in the retroflex position (odds ratio: 7.88, 95% confidence interval: 2.19-37.77, p<0.001). Conclusion Selective biliary cannulation using a short-type single-balloon enteroscope in patients with a native papilla who had undergone Roux-en-Y gastrectomy was effective and safe. The retroflex position provided a good papilla field of view and improved the success rate of biliary cannulation.

Abstract
INTRODUCTION Video capsule endoscopy and balloon-assisted enteroscopy are complementary diagnostic methods in the study of small bowel bleeding, and different factors can affect their diagnostic yield. AIMS To define the level of agreement between video capsule endoscopy and enteroscopy in small bowel bleeding, according to the type of lesion, in a cohort of patients at a tertiary care referral center. MATERIALS AND METHODS A retrospective study was conducted that included 428 capsule endoscopies performed within the time frame of 2011 and 2019 at our healthcare institution. Seventy-four video capsule endoscopies, followed by enteroscopy, in 71 patients suspected of presenting with small bowel bleeding, were analyzed. RESULTS Mean patient age was 63.9 ± 13.5 years and 42 patients were women. The two diagnostic procedures were performed. Overall diagnostic yield of positive findings between video capsule endoscopy and enteroscopy was 86.5% vs. 58.1%, respectively (p = 0.0527). Agreement between video capsule endoscopy and enteroscopy for positive pathologic findings was weak (Ik = 0.17, 95% CI: -0.0097-0.3543), but according to lesion type, it was good for inflammatory lesions (Ik = 0.71, 95% CI: 0.5182-0.9119) and moderate for angiectasias (Ik = 0.45, 95% CI: 0.2469-0.6538) and tumors (Ik = 0.40, 95% CI: 0.1217-0.6794). The results between the two methods differed in 38 patients (51.3%). There was complete intestinal capsule retention in one patient (1.4%) and active bleeding in 13 (17.6%). CONCLUSIONS The present study showed that the two techniques had a similar overall detection rate for small bowel lesions, but the type of lesion was the main factor that could modify diagnostic agreement.

Abstract
BACKGROUND Small bowel stricture is one of the most common complications in patients with Crohn's disease (CD). Endoscopic balloon dilatation (EBD) is a minimally invasive treatment intended to avoid surgery; however, whether EBD prevents subsequent surgery remains unclear. We aimed to reveal the factors contributing to surgery in patients with small bowel stricture and the factors associated with subsequent surgery after initial EBD. METHODS Data were retrospectively collected from surgically untreated CD patients who developed symptomatic small bowel stricture after 2008 when the use of balloon-assisted enteroscopy and maintenance therapy with anti-tumor necrosis factor (TNF) became available. RESULTS A total of 305 cases from 32 tertiary referral centers were enrolled. Cumulative surgery-free survival was 74.0% at 1 year, 54.4% at 5 years, and 44.3% at 10 years. The factors associated with avoiding surgery were non-stricturing, non-penetrating disease at onset, mild severity of symptoms, successful EBD, stricture length < 2 cm, and immunomodulator or anti-TNF added after onset of obstructive symptoms. In 95 cases with successful initial EBD, longer EBD interval was associated with lower risk of surgery. Receiver operating characteristic analysis revealed that an EBD interval of ≤ 446 days predicted subsequent surgery, and the proportion of smokers was significantly high in patients who required frequent dilatation. CONCLUSIONS In CD patients with symptomatic small bowel stricture, addition of immunomodulator or anti-TNF and smoking cessation may improve the outcome of symptomatic small bowel stricture, by avoiding frequent EBD and subsequent surgery after initial EBD.

Takenaka K, Fujii T, Suzuki K, Shimizu H, Motobayashi M, Hibiya S, Saito E, Nagahori M, Watanabe M, Ohtsuka K. Small Bowel Healing Detected by Endoscopy in Patients With Crohn's Disease After Treatment With Antibodies Against Tumor Necrosis Factor. Clin Gastroenterol Hepatol 2020; 18:1545-1552. [PMID: 31442600 DOI: 10.1016/j.cgh.2019.08.024] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2019] [Revised: 07/29/2019] [Accepted: 08/09/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS It is important to objectively assess Crohn's disease (CD) activity in patients treated with antibodies against tumor necrosis factor (anti-TNF). Detection of healing by endoscopy (endoscopic healing) associates with patient outcome, based on evidence from studies of ileocolonoscopy. We assessed endoscopic healing after treatment, based on findings from balloon-assisted enteroscopy (BAE), in patients with CD. METHODS We performed a post-hoc analysis of data from a clinical trial from 116 patients with CD (46 with ileal and 70 with ileocolonic type) who received induction and then maintenance therapy with anti-TNF agents from January 2013 through March 2018 at a single center in Japan. We compared findings from BAE before induction therapy and then again during maintenance therapy (median 13 months later). Endoscopic healing was defined as the modified simple endoscopic score for CD below 5. We also collected data on previous treatments, makers of inflammation, and disease type. RESULTS Before treatment, small bowel ulcerations were present in 114 patients (98%); 42 patients (60%) with ileocolonic disease had colon ulcerations. During maintenance therapy, 41/114 patients (36%) had small bowel endoscopic healing; all the patients with small bowel endoscopic healing also had colonic endoscopic healing. Colonic endoscopic healing was observed in 33/42 patients (79%). The proportion of patients with small bowel endoscopic healing was significantly lower than that of colonic endoscopic healing (P < .001). Among all patients, failure to achieve small bowel endoscopic healing was significantly associated with structuring or penetrating disease (P = .014), lack of concomitant treatment with immunomodulators (P = .015), and having received previous treatment with an anti-TNF agents (P = .018). CONCLUSIONS In a post-hoc analysis of patients with CD treated with anti-TNF agents, we found small bowel ulcerations, detected by BAE, to be more difficult to heal than colon ulcerations.

Abstract
Objective With the advent of capsule endoscopy (CE) and double-balloon endoscopy (DBE), the diagnosis and treatment of obscure gastrointestinal bleeding (OGIB) have markedly progressed. However, rebleeding sometimes occurs and is difficult to diagnose and treat. The aim of the present study was to investigate the clinical features of OGIB and risk factors for rebleeding in our hospital. Methods A total of 195 patients who underwent CE and/or DBE for OGIB in our hospital from January 2009 to July 2016 were included in the present study. We analyzed 168 cases of small intestinal OGIB, after excluding 27 cases of extra small intestinal bleeding. The clinical characteristics and risk factors related to rebleeding were retrospectively studied. Results Among the 168 patients who were included in the analysis, 95 patients (56.5%) were male. The mean age was 64.5 years (range, 8 to 87 years). Hypertension (31.0%) was the most frequent comorbidity, followed by chronic kidney disease (19.0%). The final diagnoses were ulcerative lesions (n=50, 29.8%), vascular lesions (n=30, 17.9%), tumors (n=7, 4.2%), and diverticula (n=2, 1.2%). The bleeding source was undetermined in the remaining 79 cases (47.0%). Rebleeding was confirmed in 29 cases (17.3%). In a univariate analysis, chronic kidney disease, vascular lesions, and overt previous bleeding were significantly associated with the risk of rebleeding. A multivariate analysis showed that chronic kidney disease, vascular lesion, and overt previous bleeding were significantly associated with the risk of rebleeding. Conclusion Patients with OGIB with overt previous bleeding, vascular lesions, and/or chronic kidney disease had a higher risk of rebleeding.

Abstract
Flexible colonoscopy remains the prime mean of screening for colorectal cancer (CRC) and the gold standard of all population-based screening pathways around the world. Almost 60% of CRC deaths could be prevented with screening. However, colonoscopy attendance rates are affected by discomfort, fear of pain and embarrassment or loss of control during the procedure. Moreover, the emergence and global thread of new communicable diseases might seriously affect the functioning of contemporary centres performing gastrointestinal endoscopy. Innovative solutions are needed: artificial intelligence (AI) and physical robotics will drastically contribute for the future of the healthcare services. The translation of robotic technologies from traditional surgery to minimally invasive endoscopic interventions is an emerging field, mainly challenged by the tough requirements for miniaturization. Pioneering approaches for robotic colonoscopy have been reported in the nineties, with the appearance of inchworm-like devices. Since then, robotic colonoscopes with assistive functionalities have become commercially available. Research prototypes promise enhanced accessibility and flexibility for future therapeutic interventions, even via autonomous or robotic-assisted agents, such as robotic capsules. Furthermore, the pairing of such endoscopic systems with AI-enabled image analysis and recognition methods promises enhanced diagnostic yield. By assembling a multidisciplinary team of engineers and endoscopists, the paper aims to provide a contemporary and highly-pictorial critical review for robotic colonoscopes, hence providing clinicians and researchers with a glimpse of the major changes and challenges that lie ahead.

Abstract
Recent advances in small-bowel endoscopy such as capsule endoscopy have shown that non-steroidal anti-inflammatory drugs (NSAIDs) frequently damage the small intestine, with the prevalence rate of mucosal breaks of around 50% in chronic users. A significant proportion of patients with NSAIDs-induced enteropathy are asymptomatic, but some patients develop symptomatic or complicated ulcers that need therapeutic intervention. Both inhibition of prostaglandins due to the inhibition of cyclooxygenases and mitochondrial dysfunction secondary to the topical effect of NSAIDs play a crucial role in the early process of injury. As a result, the intestinal barrier function is impaired, which allows enterobacteria to invade the mucosa. Gram-negative bacteria and endogenous molecules coordinate to trigger inflammatory cascades via Toll-like receptor 4 to induce excessive expression of cytokines such as tumor necrosis factor-α and to activate NLRP3 inflammasome, a multiprotein complex that processes pro-interleukin-1β into its mature form. Finally, neutrophils accumulate in the mucosa, resulting in intestinal ulceration. Currently, misoprostol is the only drug that has a proven beneficial effect on bleeding small intestinal ulcers induced by NSAIDs or low-dose aspirin, but its protection is insufficient. Therefore, the efficacy of the combination of misoprostol with other drugs, especially those targeting the innate immune system, should be assessed in the next step.

Abstract
BACKGROUND Short-type double-balloon endoscope (DBE)-assisted endoscopic retrograde cholangiopancreatography (ERCP) has been developed as an alternative approach for cases with a surgically altered gastrointestinal anatomy. However, this technique is sometimes technically challenging and carries a risk of severe adverse events. AIMS To evaluate the factors affecting the technical success rate and adverse events of DBE-ERCP. METHODS A total of 319 patients (805 procedures) with a surgically altered gastrointestinal anatomy underwent short DBE-ERCP. The factors affecting the technical success rate and adverse events, and the learning curve of the trainees were retrospectively evaluated. RESULTS The technical success rate of all procedures was 90.7%. Adverse events occurred in 44 (5.5%) procedures. A multivariate analysis indicated that Roux-en-Y reconstruction and first-time short DBE-ERCP were factors affecting the technical failure and adverse event rates, while the modified Child method after subtotal stomach-preserving pancreaticoduodenectomy reconstruction was a non-risk factor for adverse events. The trainee caseload did not affect the technical success or adverse event rates significantly; however, trainees tended to perform cases involving the modified Child method after subtotal stomach-preserving pancreaticoduodenectomy reconstruction. The success rate of scope insertion increased according to experience; however, the overall success rate did not differ to a statistically significant extent. CONCLUSION Short DBE-ERCP was useful and safe for managing cases with a surgically altered anatomy; however, trainees should concentrate on accumulating experience with easy cases, such as those with the modified Child method after subtotal stomach-preserving pancreaticoduodenectomy reconstruction or a history of DBE-ERCP.

Abstract
PURPOSE OF REVIEW The present review offers its readers a practical overview of protein-losing enteropathy, particularly with regard to diagnostic and therapeutic approaches. The aim is to support clinicians in their daily practice with a practical tool to deal with protein-losing enteropathy. RECENT FINDINGS The literature covering protein-losing enteropathy does not appear to be quite recent and also guidelines are scanty. The main innovations during the last decade probably regard the introduction of enteroscopic techniques in the diagnostic flowchart. The use of video-capsule and device-assisted enteroscopy has enabled the direct exploration of the small bowel and the identification of the damage causing the loss of proteins from the gastrointestinal tract. Other innovations are to do with the therapies of the disorder underlying protein-losing enteropathy, although the support with nutritional supplementation are the direct remedies to tackle the protein loss. SUMMARY Protein-losing enteropathy represents an important clinical aspect of different gastrointestinal and extra-intestinal diseases. An established flowchart is still unavailable, but the use of enteroscopy has deeply changed the modern diagnostic approach. Nutritional support and therapy of the underlying disease are pivotal to patients' management.

Abstract
BACKGROUND Double-balloon, single-balloon, and spiral enteroscopy (DBE, SBE, and SE) have revolutionized the management of intestinal diseases. However, evidence about efficacies of these methods is lacking. We aimed to conduct a meta-analysis comparing the clinical outcomes among DBE, SBE, and SE.
METHODS We searched randomized controlled trials and prospective studies in MEDLINE, PubMed, EMBASE, Cochrane Library, and Chinese CQVIP database. Studies referencing the comparison of at least two of these three methods were included. Primary outcome was diagnostic yield. Other outcomes were therapeutic yield, total enteroscopy, examination time, time to maximum insertion, and depth of maximal insertion (DMI).
RESULTS Eleven studies including 727 patients were identified: DBE vs SE (n = 6), DBE vs SBE (n = 4), and SBE vs SE (n = 1). The diagnostic and therapeutic yields did not differ significantly when comparing DBE with SE [odds ratio (OR) = 1.19, 95% confidence interval (CI): 0.68-2.08; OR = 1.17, 95%CI: 0.61-2.23] and DBE with SBE (OR = 0.85, 95%CI: 0.55-1.33; OR = 1.71, 95%CI: 0.64 - 4.60). Total enteroscopy, examination time, time to maximum insertion, and DMI were similar between SBE and DBE. DBE was superior to SE with regard to DMI [mean difference (MD) = 36.76, 95%CI: 5.09-68.43], with longer time to maximum insertion (MD = 15.14, 95%CI: 12-18.27) and examination time (MD = 12.98, 95%CI: 9.57-16.38).
CONCLUSION DBE and SBE have similar clinical outcomes. Compared with DBE, SE seems to have similar diagnostic and therapeutic yields, but shorter procedural time in cost of less depth of insertion. SE needs further evaluation vs SBE. DBE is recommended for complete enteroscopy.

Abstract
Background and Aim Cases of colorectal endoscopic submucosal dissection (ESD) with poor maneuverability are often encountered. We aimed to evaluate the efficacy of balloon‐assisted endoscopy (BAE) for such cases. Methods We confirmed maneuverability preoperatively in 400 consecutive cases of colorectal ESD performed at a single center from April 2011 to April 2018. A total of 83 deep colon cases judged as having poor maneuverability were retrospectively reviewed; 54 cases underwent BAE with a single balloon endoscope (group B), and 29 cases underwent conventional procedures without BAE (group C). Tumor size, procedure duration, dissection speed, en bloc resection rate, histology, and associated complications were compared between groups. Results The mean tumor size, tumor invasiveness, fibrosis, and complications did not differ between groups. Although the en bloc resection rate did not differ (both 98%), the groups significantly differed with regard to the R0 resection rate (B: 96%; C: 83%; P = 0.048). Overall, the procedure duration (B: 51 min; C: 70 min; P = 0.17) and dissection speed (B: 19.4 mm2/min; C: 17.4 mm2/min; P = 0.13) were not significantly different between groups. However, the dissection speed for lesions in the cecum/ascending colon was significantly faster in group B than in group C (B: 22.3 mm2/min; C: 11.3 mm2/min; P = 0.037). Conclusions In cases of colorectal ESD with poor maneuverability, the use of BAE contributed to an improvement in the R0 resection rate. In addition, BAE contributed to a quicker dissection speed for lesions located in the cecum/ascending colon.

Abstract
OBJECTIVE: The aim of this study was to evaluate the effect of double-balloon enteroscopy (DBE) on the success of endoscopic retrograde cholangiopancreatography (ERCP) procedures in patients with surgically modified gastrointestinal (GI) tract anatomy. METHODS: The medical records of patients who underwent ERCP in the Gastroenterology Department of Kocaeli University School of Medicine hospital between December 2008 and September 2014 were examined. From the patient group that was scheduled to undergo DBE-ERCP, the details of cases in which ERCP via standard duodenoscope or DBE-ERCP was performed during the same session because standard ERCP failed were included. Procedure parameters, outcomes, and complications related to the procedure in both groups were analyzed. Patients who underwent the DBE-ERCP procedure directly, those who underwent push enteroscopy, or gastroscopy to evaluate the GI tract anatomy before the day of ERCP, and who underwent DBE-ERCP on a day other than the initial ERCP session were excluded. Afferent loop intubation, access to the major papilla, selective cannulation, therapeutic success rates, and the effect of DBE on overall procedure success were evaluated. RESULTS: Fifty-one patients with a history of BII gastrojejunostomy and 11 patients with hepaticojejunostomy (with or without Roux-en-Y) were included in the study. In all patients, the ERCP procedure was initiated with a standard duodenoscope. If intubation of the afferent loop was unsuccessful in reaching the major papilla or enterobiliary anastomosis, DBE was used. In 30 (48.4%) of the 62 patients whose GI tract was anatomically altered, the duodenoscope was successfully advanced to the ampulla and 27 (43.5%) were cannulated successfully. Thirty-one patients underwent DBE-ERCP. DBE reached the ampulla or enterobiliary anastomosis in 30 patients (96.8%) and selective choledocus cannulation was achieved in all patients but 3 (90%), including 1 patient with a hepaticojejunostomy. The overall ERCP success rate increased from 43.5% (27/62) to 87.1% (54/62). Two perforations (1 during standard duodenoscopy and 1 with DBE-ERCP) were observed. CONCLUSION: The overall success rate of ERCP increased with use of the DBE technique in patients with small bowel anatomic variations that were the result of previous surgery.

Abstract
Within the project "Quality Indicators in Gastrointestinal Endoscopy," under the leadership of the Sociedad Española de Patología Digestiva (SEPD), our goal is to propose the procedures and the structure, process, and outcome indicators required for the application and assessment of quality in enteroscopy. To this end a search was performed for quality indicators in enteroscopy. Quality of evidence was measured by using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system, and classified as high, moderate, low, and very low. A total of 10 process indicators (one preprocedure, eight procedure, one postprocedure) were identified for enteroscopy, with appropriate indication and choice of most efficient route being most significant.

Abstract
The small bowell (SB) is a very long organ hardly accessible to conventional endoscopy. The revolution entailed by its complete diagnostic exploration with capsule endoscopy (CE) has led to a change in traditional surgical management and its related gold standard - intraoperative enteroscopy. CE is currently the first-line diagnostic strategy for the SB. An emergent technique in its wake has played a key role in the management of patients with SB conditions: to wit, device-assisted enteroscopy (DAE). Thus were developed first double-balloon enteroscopy (DBE), then single-balloon enteroscopy, and most recently motorized spiral enteroscopy.

Abstract
BACKGROUND Owing to the development of double-balloon enteroscopy (DBE) and video capsule endoscopy (VCE) in recent years, direct visualization of the entire small intestinal mucosa has become possible. Because of the nonspecific symptoms and the anatomic location of the small bowel, diagnosis of isolated small bowel Crohn's disease (CD) remains a challenge. The aim of this research was to explore the value of DBE for isolated small bowel CD in situations where routine tests cannot confirm the diagnosis. METHODS This study included patients with suspected isolated small bowel CD who were hospitalized in Shengjing Hospital from April 2014 to June 2018. We included patients presenting with chronic diarrhea, abdominal pain, abdominal mass, perianal lesions, and systemic symptoms including weight loss, fever, and anemia after excluding infection factors. Patients with purely colonic CD were excluded from this cohort. Patients with suspected isolated small bowel CD underwent DBE. RESULTS In 16/18 patients, pathological findings were detected by DBE. In 12 of the cases, small bowel CD was confirmed. The remaining four patients were diagnosed with small bowel inflammation, duodenal carcinoma, ileum inflammation and small bowel ulcers. However, the diagnosis of CD was confirmed in 14/18 (78%) patients by taking into account the clinical presentation, endoscopic and histological results as well as the experimental treatment. DBE assisted in the diagnosis in 86% (12/14) of the patients. CONCLUSIONS In the diagnosis of small bowel CD, DBE is a helpful tool. Before assessment with DBE, clinical features, colonoscopy, and CT were used to initially assess the intestine. According to the lesions indicated by CT, we chose the most appropriate endoscope insertion route, and combined the endoscopic characteristics and pathological results of DBE to confirm the diagnosis.

Abstract
Background Double balloon enteroscopy (DBE) is a diagnosis and therapy method for suspected small bowel bleeding (SSBB). The data for emergent DBE is limited in overt SSBB cases. The aim of this study was to investigate the role of diagnosis and therapy of emergent DBE in patients with overt SSBB. Material/Methods The clinical and endoscopic data for patients with overt SSBB undergoing DBE in a single center from January 2010 to December 2017 were collected and analyzed. Emergent DBE was defined as DBE performed less than 3 days of last bleeding onset. Results A total of 265 DBEs in 265 patients with overt SSBB were enrolled (mean age, 44.7±17.3 years; 66.8% males). The patients were divided into 3 groups according to the timing of DBE: less than 3 days (n=32), more than 3 days and less than 7 days (n=146), and more than 7 days (n=87) (first group was the emergent group, the latter 2 groups were the non-emergent groups). The diagnosis yield for the emergent group was significantly higher than the non-emergent groups (84.4% versus 65.1% or 59.8%, respectively, P<0.05), but was not different between the 2 non-emergent groups (P>0.05). The top 3 diagnoses were angioectasias (19.6%), diverticulum (16.2%), and tumor (12.1%). For therapy yield, there was a remarkable reducing trend in the emergent group (<3 days), and the 2 non-emergent groups (3 to 7 days group and >7 days group: 78.1%, 58.2% and 39.1%, respectively, P<0.05. The top 3 endoscopic treatments were hemostatic clips (21.9%), argon plasma coagulation (15.8%), and epinephrine injection (14.0%). Conclusions The emergent DBE had the highest yields for diagnosis and therapy. The study finding showed a pivotal role of emergent DBE in overt SSBB.

Abstract
BACKGROUND AND AIMS Double balloon enteroscopy (DBE) has revolutionised the diagnosis and treatment of small bowel (SB) conditions. However, deep SB insertion can be challenging in patients with a history of abdominal surgery and a two-step procedure is required when findings are not amenable to endoscopic therapy. This case series reports the development of laparoscopically assisted DBE (LA-DBE) using single incision laparoscopic surgery (SILS). METHODS Retrospective review of LA-DBE procedures performed in a single tertiary centre over 6 years. RESULTS Seventeen patients (median age: 40 years, male 41%) underwent 17 LA-DBE procedures. The approach was oral in 13 and rectal in 4. Laparoscopic approach was standard (multi-port) in the first four cases, SILS was then used in all subsequent patients (13/17). Indications for LA-DBE were previously failed standard DBE (n = 16) and need for a combined procedure (n = 1). Indications for DBE were Peutz-Jeghers syndrome (PJS) (n = 10), suspected submucosal/polypoid lesion at small bowel imaging (n = 5) and obscure gastrointestinal bleeding (OGIB) with vascular abnormalities seen at capsule endoscopy (n = 2). In 1/17 the suggested pathology on imaging was not identified. Therapy was applied in 15/17 (88%) cases. Diagnoses were PJS polyps (n = 8), neuroendocrine tumour (NET) (n = 2), PJS and NET (n = 1), transmural arteriovenous malformation (n = 1), angioectesia (n = 1), inflammatory polyp (n = 1), leiomyoma (n = 1) and Meckel's diverticulum (n = 1). The median (range) procedure time was 147 (84-210) mins. Median (range) length of stay post-procedure was 2 (1-19) days. Three patients developed complications. The 30-day mortality rate was 0%. CONCLUSIONS LA-DBE is a safe, effective and minimally invasive procedure that can be applied for the management of selected patients with small bowel pathology. A SILS approach allows all therapeutic modalities to be available, including conversion to intraoperative enteroscopy (IOE), laparoscopic small bowel resection and laparotomy.

Abstract
Introduction. The relevance of the study is caused by the difficulties in diagnosing diseases of the small bowel (SB). Due to the prevalence and widespread introduction of X-ray computed tomography (CT) into clinical practice, its capabilities in the diagnosis of small bowel diseases are of great interest and potential.
Objective. to reveal the possibilities of computed tomography using intravenous bolus contrast enhancement in identifying the symptom of wall thickening of the small bowel and its prognostic significance in various nosologies.
Methods. Analysis of the data from MSCT studies performed according to the Protocol for the study of abdominal organs using intravenous bolus contrast enhancement and oral water intake in adult patients from 18 to 87 years of age with small bowel diseases.
Results. The article shows the possibilities of multispiral computed tomography performed according to the standard Protocol in detecting thickening of the SB wall. The range of diseases was determined for which thickening of the SB wall was one of the main radiological symptoms of the lesion. The prognostic significance of this radiological symptom is presented. The features of thickening of the intestinal wall in various diseases and other distinctive features that can be used in the differential diagnosis are described.
Conclusion. Thickening of the wall is a common sign of SB damage, which is convincingly detected in CT studies with bolus contrast enhancement. In our study, the common causes of thickening of the SB wall in primary disease were: Crohn's disease (37%), lymphoma (20%) and anastomosis (13%). However, we determined thickening of the SB wall as a result of primary tumors (adenocarcinoma, sarcoma) in 7% and as a result of a secondary tumor lesion in 18.6% of cases. The considered diseases were different in the degree of thickening of the intestinal wall (from 6 to 70 mm), its spreading (focal thickening 48%; segmental 52%), number of affected areas (from 1 to 3) of their localization (proximal-middle or distal section), form of the transition area from the affected part of the intestine to the unchanged one (sharply defined or smooth), the presence or absence of symptoms of intestinal obstruction, and the features of contrast enhancement (severity and type).

Abstract
Non-variceal gastrointestinal bleeding (GIB) is a significant cause of mortality and morbidity worldwide which is encountered in the ambulatory and hospital settings. Hemorrhage form the gastrointestinal (GI) tract is categorized as upper GIB, small bowel bleeding (also formerly referred to as obscure GIB) or lower GIB. Although the etiologies of GIB are variable, a strong, consistent risk factor is use of non-steroidal anti-inflammatory drugs. Advances in the endoscopic diagnosis and treatment of GIB have led to improved outcomes. We present an updated review of the current practices regarding the diagnosis and management of non-variceal GIB, and possible future directions.

Abstract
Access to the small bowel by means of an enteroscope is difficult, even using current devices such as single-balloon or double-balloon enteroscopes. Exploration time and patient discomfort are the main drawbacks. The prototype ‘Endoworm’ analysed in this paper is based on a pneumatic translation system that, gripping the bowel, enables the endoscope to move forward while the bowel slides back over its most proximal part. The grip capacity is related to the pressure inside the balloon, which depends on the insufflate volume of air. Different materials were used as in vitro and ex vivo models: rigid polymethyl methacrylate, flexible silicone, polyester urethane and ex vivo pig small bowel. On measuring the pressure–volume relationship, we found that it depended on the elastic properties of the lumen and that the frictional force depended on the air pressure inside the balloons and the lumen’s elastic properties. In the presence of a lubricant, the grip on the simulated intestinal lumens was drastically reduced, as was the influence of the lumen’s properties. This paper focuses on the Endoworm’s ability to grip the bowel, which is crucial to achieving effective endoscope forward advance and bowel folding.

Abstract
Endoscopic submucosal dissection (ESD) is a minimally invasive therapeutic procedure to remove larger polyps or early non-metastatic lesions. It has long been used in Asia, but is now fast growing in popularity in the West. There are multiple challenges faced by ESD practitioners. While the practice of ESD in gastric lesions is relatively well established, the oesophagus with its narrow lumen and challenging workspace, and the colon with its tortuous course and folds are more challenging frontiers. The nature of performing a procedure endoscopically means that conventional methods offer no mechanism for providing counter-traction while performing dissection, impeding visibility and increasing the rate of complications. There are a multitude of tools available to those performing ESD for the different stages of the procedure. This article reviews the accessories currently used in regular ESD practice including the knives used to cut and dissect lesions, the cap and hood devices used to improve visibility and safety, injection fluids to lift the submucosal plane, haemostatic devices, generators, and finally, emerging traction apparatus. There is some evidence behind the use of these tools, however, ESD remains the domain of a small number of practitioners and the practice relies heavily on expert experience. Evolution of the ESD toolbox will make the procedure more accessible to more endoscopists, which in turn will drive the development of a more substantial evidence base to evaluate efficacy and safety of the multitude of tools.

Abstract
INTRODUCTION Diaphragm disease is rare and caused by intestinal obstruction due to nonsteroidal anti-inflammatory drugs (NSAIDs). Given the availability of video capsule endoscopy (VCE) and balloon enteroscopy (BE) this disease will be diagnosed more often. PRESENTATION OF CASE A 73-year-old man was presented to our hospital for persistent nausea and vomiting. Abdominal ultrasound and computed tomography revealed small-bowel thickening, stricture in the terminal ileum, and dilation of the proximal small intestine. Differential diagnosis included ileal lymphoma and multiple ileal adenocarcinomas, and a diagnostic laparoscopy was performed. Twenty-centimeter of ileum was resected by primary ileo-ileal anastomosis. On pathological examination, fibrosis of the submucosa was identified, and erosions and numerous inflammatory cells reaching the submucosa were also identified from the specimen. DISCUSSION The preoperative diagnosis of diaphragm disease is sometimes challenging due to its uncharacteristic symptoms; moreover, radiological findings are usually indefinite and distinctive. Currently, the main treatment for diaphragm disease is surgery. CONCLUSION We have documented a case of intestinal obstruction by NSAIDs. However, it is desirable to determine the course of treatment based on small bowel endoscopic dilatation cases in the future.

Abstract
Small-bowel bleeding accounts for the majority of obscure gastrointestinal bleeding, but it is caused by various types of small bowel disease, upper gastrointestinal disease, and colorectal disease. For the diagnosis, history taking and physical examination are required, leading to a determination of what diseases are involved. Next, cross-sectional imaging, such as computed tomography, should be carried out, followed by the latest enteroscopy such as small bowel capsule endoscopy and deep enteroscopy according to the severity of hemorrhage and patient condition. After a comprehensive diagnosis, medical, enteroscopic, or surgical treatment should be selected. This article reviews recent advances in the endoscopic diagnosis of obscure gastrointestinal bleeding and compares perspectives of the management of obscure gastrointestinal bleeding in Japan with that in other countries.

Abstract
PURPOSE Wireless Capsule Endoscopy (WCE) is a minimally invasive diagnosis tool for lesion detection in the gastrointestinal tract, reaching places where conventional endoscopy is unable to. However, the significant amount of acquired data leads to difficulties in the diagnosis by the physicians; which can be eased with computer assistance. This paper addresses a method for the automatic detection of tumors in WCE by using a two-step based procedure: region of interest selection and classification. METHODS The first step aims to separate abnormal from normal tissue by using automatic segmentation based on a Gaussian Mixture Model (GMM). A modified version of the Anderson method for convergence acceleration of the expectation-maximization (EM) algorithm is proposed. The proposed features for both segmentation and classification are based on the CIELab color space, as a way of bypassing lightness variations, where the L component is discarded. Tissue variability among subjects, light inhomogeneities and even intensity differences among different devices can be overcome by using simultaneously features from both regions. In the second step, an ensemble system with partition of the training data with a new training scheme is proposed. At this stage, the gating network is trained after the experts have been trained decoupling the joint maximization of both modules. The partition module is also used at the test step, leading the incoming data to the most likely expert allowing incremental adaptation by preserving data diversity. RESULTS This algorithm outperforms others based on texture features selected from Wavelets and Curvelets transforms, classified by a regular support vector machine (SVM) in more than 5%. CONCLUSIONS This work shows that simpler features can outperform more elaborate ones if appropriately designed. In the current case, luminance was discarded to cope with saturated tissue, facilitating the color perception. Ensemble systems remain an open research field. In the current case, changes in both topology and training strategy have led to significant performance improvements. A system with this level of performance can be used in current clinical practice.

Analysis of the factors involved in procedural failure: Endoscopic retrograde cholangiopancreatography using a short-type single-balloon enteroscope for patients with surgically altered gastrointestinal anatomy. Dig Endosc 2019; 31:682-689. [PMID: 30942924 DOI: 10.1111/den.13414] [Citation(s) in RCA: 32] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/08/2019] [Accepted: 03/29/2019] [Indexed: 12/31/2022]
Abstract
AIM To analyze factors involved in procedural failure and to discuss responses to procedural failure by using the outcomes of endoscopic retrograde cholangiopancreatography (ERCP) carried out using a short-type single-balloon enteroscope (short SBE) in patients with surgically altered gastrointestinal anatomy. METHODS The study sample included patients who underwent ERCP-related procedures using a short SBE between September 2011 and September 2018 at our hospital. Outcomes, including procedural success rate, were studied retrospectively to analyze the factors involved in procedural failure. RESULTS Analysis included 191 procedures carried out in 121 patients. Procedural success rate was 85.9% with an adverse event rate of 8.4%. Causes of procedural failure included malignant biliary obstruction (odds ratio [OR] 2.89, 95% confidence interval [CI] 1.19-7.25, P = 0.02), first ERCP attempt (OR: 5.32, 95% CI: 1.30-36.30, P = 0.02), and Roux-en-Y reconstruction (OR: 0.08, 95% CI: 0.004-0.39, P < 0.001). With regard to the response to failure, in cases of malignant biliary obstruction, reattempted short SBE-assisted ERCP was difficult because of invasion of the small intestine or papilla. A large number of these cases required alternative treatment (10 of 15 cases, 66.7%) using percutaneous transhepatic biliary drainage (PTBD) or endoscopic ultrasound-guided biliary drainage (EUS-BD). CONCLUSION Endoscopic retrograde cholangiopancreatography using a short SBE is safe and effective, with malignant biliary obstruction being a specific cause of failure. Technical proficiency with different modalities, such as PTBD and EUS-BD, is necessary to respond to failure in these cases.

Abstract
Over the last decade, impressive technological advances have occurred in ultrasonography and small-bowel endoscopy. Nowadays, endoscopic ultrasonography is an essential diagnostic tool and a therapeutic weapon for pancreatobiliary disorders. Capsule endoscopy and device-assisted enteroscopy have quickly become the reference standard for the diagnosis of small-bowel luminal diseases, thereby leading to radical changes in diagnostic and therapeutic pathways. We herein provide an up-to-date overview of the latest advances in endoscopic ultrasonography and small-bowel endoscopy, focusing on the emerging paradigms and technological innovations that might improve clinical practice in the near future.

Hashimoto R, Nakahori M, Matsuda T. Impact of Urgent Double-Balloon Enteroscopy on the Short-Term and Long-Term Outcomes in Overt Small Bowel Bleeding. Dig Dis Sci 2019; 64:2933-2938. [PMID: 30997580 DOI: 10.1007/s10620-019-05627-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2019] [Accepted: 04/12/2019] [Indexed: 02/08/2023]
Abstract
BACKGROUND Double-balloon enteroscopy (DBE) is a safe and useful procedure for managing small bowel bleeding. However, there are limited studies regarding the preferable timing of DBE and its impact on long-term outcomes. AIM We aimed to evaluate the association between the timing of DBE and the long-term outcomes of patients suspected of having overt small bowel bleeding who underwent DBE. METHODS We retrospectively reviewed a prospectively collected database of patients who underwent DBE procedures between May 2004 and April 2016. The electronic medical records were reviewed, and interviews were conducted via mail and telephone. RESULTS One-hundred sixty-five patients could be followed up. The bleeding source was detected during the initial DBE (DBE-positive group) for 102 patients. Sixty-three patients had no definite lesion during the initial DBE (DBE-negative group). Urgent DBE (DBE within 24 h after the last bleeding episode) was performed more often for the DBE-positive group (50/102; 49.0%) than for the DBE-negative group (10/63; 16.1%) (p < 0.0001). Nine patients in the DBE-positive group underwent curative surgery after diagnosis. Among the remaining DBE-positive patients, 38 of 93 (40.9%) had recurrent bleeding during 2675 days of follow-up. Twenty-one of 63 patients (33.3%) in the DBE-negative group had recurrent bleeding during 2490 days of follow-up. There was no significant difference between the two groups in terms of intervals without rebleeding (p = 0.17). CONCLUSION Urgent DBE at the initial bleeding episode was useful for detecting lesions. However, the rebleeding rate was not dependent on the initial DBE results.
