Abstract
Upper gastrointestinal cancers are among the leading causes of cancer deaths worldwide with exceptionally poor prognosis, which is largely attributable to frequently delayed diagnosis. Although effective screening is critical for early detection, the highly variable incidence of upper gastrointestinal cancers presents challenges, rendering universal screening programs suboptimal in most populations globally. Optimal strategies in regions of modest incidence, such as the United States, require a targeted approach, focused on high-risk individuals based on demographic, familial, and clinicopathologic risk factors. Assessment of underlying precancerous lesions has key implications for risk stratification and informing clinical decisions to improve patient outcomes.

Abstract
A retrospective study in patients who underwent video capsule endoscopy (VCE) between 2006 and 2016 was conducted in the Clinic for gastroenterology and Hepatology, University Clinical Center of Serbia. A total of 245 patients underwent VCE. In 198 patients the indication was obscure gastrointestinal bleeding (OGIB), with 92 patients having overt and the other 106 occult bleeding. The remaining 47 patients underwent VCE due to suspected small bowel (SB) disease (i.e., Von Hippel-Lindau syndrome, familial adenomatous polyposis, Peutz Jeghers syndrome, Crohn's disease, prolonged diarrhea, abdominal pain, congenital lymphangiectasia, protein-losing enteropathy, tumors, refractory celiac disease, etc.). VCE identified a source of bleeding in 38.9% of patients (in the obscure overt group in 48.9% of patients, and in the obscure occult group in 30.2% of patients). The most common findings were angiodysplasias, tumors, Meckel's diverticulum and Crohn's disease. In the smaller group of patients with an indication other than OGIB, 38.3% of patients had positive VCE findings. The most common indication is OGIB, and the best candidates are patients with overt bleeding; patients with IBD should be evaluated in this setting.

Performance of capsule endoscopy for the detection of small intestinal neuroendocrine tumors in familial carcinoid: a prospective single-site study. Gastrointest Endosc 2024; 99:227-236. [PMID: 37838323 DOI: 10.1016/j.gie.2023.08.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Revised: 08/30/2023] [Accepted: 08/31/2023] [Indexed: 10/16/2023]
Abstract
BACKGROUND AND AIMS Small-bowel neuroendocrine tumors (NETs) are slow growing, clinically silent tumors whose prognosis depends on disease stage. Members of kindreds with a familial form of small intestinal NETs (SI-NETs) represent a high-risk population for whom early detection improves disease outcome. Our aim was to determine the utility of small-bowel capsule endoscopy (SB-CE) for screening high-risk asymptomatic relatives from kindreds with familial carcinoid. METHODS One hundred seventy-four asymptomatic subjects with a family history (≥2 family members) of SI-NETs were screened under Protocol NCT00646022, Natural History of Familial Carcinoid Tumor at the National Institutes of Health. All patients were imaged with SB-CE and 18fluoro-dihydroxphenylalanine (18F-DOPA) positron emission tomography (PET)/CT, and results were independently analyzed. Patients with a positive imaging study underwent surgical exploration. RESULTS Thirty-five of 174 asymptomatic subjects screened for SI-NETs were positive on either SB-CE or 18F-DOPA PET. Thirty-two of 35 patients with a positive study were confirmed at surgery. SB-CE was positive in 28 of 32 patients with confirmed tumors for a per-patient sensitivity of 87.5%. SB-CE had a specificity of 97.3% and a negative predictive value of 96.5%. The average tumor number and size were 7.7 and 5.0 mm, respectively, and 81.2% of patients had multiple tumors. 18F-DOPA PET/CT had a similar sensitivity of 84% versus surgery. CONCLUSIONS SB-CE is a sensitive and specific method comparable with 18F-DOPA PET/CT for screening high-risk patients with familial SI-NET. (Clinical trial registration number: NCT00646022.).

The professional background of a referring physician predicts the diagnostic yield of small bowel capsule endoscopy in suspected small bowel bleeding. Endosc Int Open 2024; 12:E282-E290.

Abstract
Background and study aims The diagnostic yield of small-bowel capsule endoscopy (SBCE) in suspected small bowel bleeding (SSBB) is highly variable. Different reimbursement systems and equipment costs also limit SBCE use in clinical practice. Thus, minimizing non-diagnostic procedures is advisable. This study aimed to assess the SBCE diagnostic yield and identify factors predicting diagnostic findings in a cohort of patients with SSBB. Patients and methods In this retrospective cohort study, we analyzed the medical records of patients who consecutively underwent SBCE for SSBB over 9 years. By logistic regression, we identified covariates predicting diagnostic findings at SBCE. Finally, we performed a post-hoc cost analysis based on previous gastroenterologist or endoscopist consultations versus direct SBCE ordering by other specialists. Results The final analysis included 584 patients. Most SBCEs were ordered by a gastroenterologist or endoscopist (74%). The number of SBCEs without any finding was significantly lower in the gastroenterologist/endoscopist group P <0.001). The SBCE diagnostic yield ordered by a gastroenterologist or endoscopist was significantly higher than that by other specialists (63% vs 52%, odds ratio [OR] 1.57; 95% confidence interval [CI] 1.07-2.26, P =0.019). At multivariate analysis, older age (OR 1.7, 95%CI 1.2-2.4, P =0.005), anemia (OR 4.9, 95%CI 1.9-12, P =0.001), small bowel transit time (OR 1, 95%CI 1-1.02, P =0.039), and referring physician (OR 1.8, 95%CI 1.1-2.7, P =0.003) independently predicted diagnostic findings. Implementing prior gastroenterologist or endoscopist referral vs direct SBCE ordering would reduce medical expenditures by 16%. Conclusions The professional background of referring physicians significantly improves the diagnostic yield of SBCE and contributes to controlling public health costs.

Abstract
Melanoma is a cancer that frequently metastasises to the small bowel, but most cases are asymptomatic and are diagnosed postmortem. Therefore, CT and PET CT cannot detect all lesions and conventional endoscopic study only detects 10-20% of lesions. In this study, we present the case of a 68-year-old patient with a history of cutaneous melanoma and a diagnosis of intestinal melanoma. Thanks to capsule endoscopy, two lesions compatible with cutaneous melanoma metastasis to the small bowel were detected, allowing a much more effective surgical planning. Capsule endoscopy is an innovative technique that improves preoperative diagnosis, as it is able to detect bowel segments that cannot be inspected by conventional endoscopy. It also has a better resolution than conventional CT, improving sensitivity in the detection of lesions.

Abstract
The incidence of intestinal cancer has risen significantly. Because of the many challenges posed by the complex environment of the intestine, it is difficult to diagnose accurately and painlessly using conventional methods, which requires the development of new body-friendly diagnostic methods. Micro- and nanomotors show great potential for biomedical applications in restricted environments. However, the difficulty of recycling has been a constraint in the collection of biological tissues for diagnostic purposes. Here, we propose a multi-functional "medical ship" (MFMS) that can be rapidly driven by a magnetic field and can reversibly "open" and "close" its internal storage space under NIR laser irradiation. It provides a transportation and recovery platform for micro- and nanomotors and cargoes. In addition, fast selection of the MFMS and magnetic nanoparticles (MNPs) can be realized through adjusting the strength and frequency of the external magnetic field. Rapid encapsulation of intestinal tissues by MNPs was achieved using a low-frequency rotating magnetic field. In addition, we demonstrated the controlled release of MNPs using the MFMS and the collection of intestinal tissues. The proposed MFMS is an intelligent and controllable transportation platform with a simple structure, which is expected to be a new tool for performing medical tasks within the digestive system.

Abstract
Lung adenocarcinoma commonly metastasizes to the lymph nodes, bone, nervous system, liver, respiratory system, and adrenal gland. Metastasis to the small bowel is extremely rare and the literature deals mostly with few published case reports. We present a case of a 70-year-old male with a previous history of stage IV lung adenocarcinoma with brain and liver metastases treated with radiotherapy and chemotherapy. He presented to the emergency department with peritonitis and sepsis due to bowel perforation. He underwent an emergency exploratory laparotomy and small bowel resection. Surgical pathology revealed metastatic lung adenocarcinoma as the cause of bowel perforation. He tolerated and recovered from surgery well and was discharged on postoperative day 7. On one-month follow-up as an outpatient, he was doing well and had no complications or complaints from his recent surgery.

Abstract
INTRODUCTION Capsule endoscopy has had significant development since it was introduced into the field of medicine in 2000. It is non-invasive, well tolerated, does not require sedation and is a first-line small bowel investigative modality. As it transits through the entire gastrointestinal (GI) tract, it has the potential to provide a pan-enteric examination. AREAS COVERED In this review we will discuss the new diagnostic modalities along with traditional methods which have been used for examination of the gastro intestinal (GI) tract. The main focus of this review will be on the use of capsule endoscopy for pan-enteric examination. EXPERT OPINION Capsule endoscopy is an accepted first-line investigation for the small bowel. Diagnostic sensitivity of the colon capsule is comparable to colonoscopy in controlled trials and is being evaluated in high-risk patients in routine clinical practice in national programs. Preliminary data suggest that a magnetic-controlled examination of the upper GI tract could be developed to enable a complete upper GI examination.

Abstract
Simple Summary Small bowel adenocarcinoma is a rare tumor. Diagnosis is often obtained at an advanced stage and prognosis remains poor. The aim of this review is to report the recent epidemiological and risk factor data related to small bowel adenocarcinoma. New diagnostic tools are also described in this review. Abstract Adenocarcinomas of the small intestine are rare tumors but their incidence is increasing. There is a slight male predominance. The median age at diagnosis is the 6th decade. The most frequent primary location is the duodenum. There is no clearly identified environmental risk factor, but adenocarcinomas of the small intestine are associated in almost 20% of cases with predisposing diseases (Crohn’s disease, Lynch syndrome, familial adenomatous polyposis, Peutz–Jeghers syndrome and celiac disease).

Abstract
PURPOSE OF REVIEW The diagnosis of small bowel lymphoma (SBL) can be challenging, as they are very rare and also have a varied presentation. In this review, we aim to provide a broad overview of the types of SBL and also about the various modalities used for their diagnosis. We also discuss the overview of treatment strategies for a gastroenterologist. RECENT FINDINGS Small bowel capsule endoscopy (SBCE) and devise-assisted enteroscopy (DAE) has revolutionized the way we investigate the small bowel. DAE also makes it possible to obtain histological samples for further characterization of SBL. This has led to a significant improvement in diagnosis and management of the disease in conjunction with cross-sectional imagining. SUMMARY The diagnosis and management of small bowel lymphoma remains challenging despite the development of newer techniques such as SBCE and DAE. The current available diagnostic modalities have limitations; in the absence of a gold standard, the current investigative modalities compliment each other in reaching the final diagnosis.

Abstract
Observing the entire small bowel is difficult due to the presence of complex loops and a long length. Capsule endoscopy (CE) provides a noninvasive and patient-friendly method for visualizing the small bowel and colon. Small bowel capsule endoscopy (SBCE) has a critical role in the diagnosis of small bowel disorders through the direct observation of the entire small bowel mucosa and is becoming the primary diagnostic tool for small bowel diseases. Recently, colon capsule endoscopy (CCE) was also considered safe and feasible for obtaining sufficient colonic images in patients with incomplete colonoscopy, in the absence of bowel obstruction. This review article assesses the current status of CE in terms of the diagnostic yield and the clinical impact of SBCE in patients with obscure gastrointestinal bleeding, who have known or suspected Crohn's disease, small bowel tumor and inherited polyposis syndrome, celiac disease, and those who have undergone CCE.

Abstract
BACKGROUND AND AIMS Small bowel capsule endoscopy (SBCE) does not reach the cecum within the battery lifetime in approximately 15-35% of patients. Incomplete examinations result in diagnostic delays and increase the economic burden. To date, risk factors for incomplete examinations have been described with contradictory results. The aims of this study were to analyze rate and identify risk factors for incomplete examinations, excluding capsule retentions, in a large cohort of patients. METHODS Data from 1894 consecutive SBCE examinations performed from January 2009 to December 2015 were analyzed. Variables recorded included demographics, past medical and surgical history, biochemical parameters and procedure characteristics. The rate of incomplete examinations, excluding capsule retentions, was calculated and a multivariate analysis using a logistic regression model was performed in order to evaluate predictive factors. RESULTS The incidence of incomplete examinations, excluding capsule retentions, was 10.1% (187 incomplete procedures). The multivariate analysis showed that age >65 years, gastric transit time >41 minutes and SB transit time >286 minutes are predictive factors for incomplete examinations, increasing the probability of this event by 199% (OR:1.99; CI95%:1.34-2.95), 260% (OR:2.60; CI95%:1.72-3.93) and 352% (OR:3.52; CI95%:2.26-5.48), respectively. CONCLUSIONS Age >65 years, gastric transit time >41 minutes and SB transit time >286 minutes are predicting factors for incomplete examinations excluding capsule retentions. Both age and gastric transit time events are known before procedure ending. Therefore, pharmacologic or endoscopic measures may be taken into account to avoid incomplete examinations.

Abstract
Small bowel malignant tumours make only 2% of all gastrointestinal (GI) malignancies. Small bowel leiomyosarcoma (LMS) is further rare, accounts for only 0.1%-3% fraction of these tumours. These cases can present as asymptomatic intra-abdominal mass, anaemia due to GI bleed or acute abdomen such as perforation peritonitis, intussusception and bowel ischaemia. Standard of care is surgical resection. Our case presented as large lobulated exophytic ileal LMS measuring 10.8×11×14.7 cm involving multiple small bowel loops and abutting right iliac vessels and uterus. Patient's clinical course was complicated with COVID-19 positivity, deep vein thrombosis and pulmonary thromboembolism. She was managed by preoperative anticoagulation followed by resection of the tumour with end ileostomy.

Lee SP, Lee J, Kae SH, Jang HJ, Jung ES. Effect of Nonsteroidal Anti-inflammatory Agents on Small Intestinal Injuries as Evaluated by Capsule Endoscopy. Dig Dis Sci 2021; 66:2724-2731. [PMID: 32748299 DOI: 10.1007/s10620-020-06511-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2020] [Accepted: 07/21/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND Currently, because the population is aging, use of medications has been increasing, including use of nonsteroidal anti-inflammatory drugs (NSAIDs) and antithrombotic agents. AIMS This study aims to investigate whether NSAIDs can cause damage to the small bowel (SB) mucosa. METHODS Endoscopic videos of subjects who had undergone capsule endoscopy (CE) were evaluated by three experts in order to identify SB injury. All medications taken within 2 weeks from the time of CE were investigated. Cases with a final diagnosis of intestinal tuberculosis, inflammatory bowel disease, Behcet's disease, Peutz-Jeghers syndrome, small bowel lymphoma, or Henoch-Schönlein purpura were excluded from the analysis. RESULTS Among the 273 subjects, 125 (45.8%) had SB erosions or ulcers (erosion group) and the remaining 148 (54.2%) did not (no erosion group). SB erosions or ulcers were more common in females, patients aged > 60 years, and subjects taking NSAIDs (p = 0.048, 0.032, and < 0.001, respectively). No statistically significant differences were found between the two groups in the following variables: history of cancer and GI surgery, reasons for the test, comorbidities, and use of anticoagulants and antiplatelet agents. Multivariate analysis showed that use of NSAIDs [OR 4.191 (95% CI 1.858-9.458), p < 0.001] was an independent risk factor for SB erosions or ulcers. CONCLUSIONS Use of NSAIDs is the only independent risk factor for SB injury identified in this study. Antithrombotic agents do not cause or exacerbate damage to the SB, according to our results.

Abstract
PURPOSE OF REVIEW Peutz-Jeghers syndrome is a rare, autosomal dominant, hereditary polyposis syndrome defined by gastrointestinal hamartomas and mucocutaneous pigmentations, caused by a germline mutation in the serine/ threonine kinase 11 or liver kinase B1 (STK11/LKB1) genes. Hamartomatous polyps located throughout the gastrointestinal tract can be complicated by bleeding and small bowel intussusception, potentially leading to the need for emergency surgery. Individuals suffering from Peutz-Jeghers syndrome have an increased lifetime risk of various forms of cancer (gastrointestinal, pancreatic, lung, breast, uterine, ovarian and testicular). Surveillance should lead to the prevention of complications and thus a reduction in mortality and morbidity of patients. RECENT FINDINGS A combined approach based on wireless capsule endoscopy, magnetic resonance enterography and device-assisted enteroscopy is effective in reduction of the polyp burden and thus decreasing the risk of bleeding and intussusception. Current guidelines for screening and surveillance are mostly based on expert opinion rather than evidence. SUMMARY Peutz-Jeghers syndrome is an emerging disease that significantly affects the quality of life enjoyed by patients. Despite of all the progress in improved early diagnostics, options for advanced endoscopic therapy and elaborate surveillance, acute and chronic complications decrease the life expectancy of patients suffering from Peutz-Jeghers syndrome.

Abstract
PURPOSE OF REVIEW Systemic diseases can afflict the small bowel (SB) but be challenging to diagnose. In this review, we aim to provide a broad overview of these conditions and to summarise their management. RECENT FINDINGS Small bowel capsule endoscopy (SBCE) is an important modality to investigate pathology in the SB. SB imaging can be complementary to SBCE for mural and extramural involvement and detection of multiorgan involvement or lymphadenopathy. Device assisted enteroscopy provides a therapeutic arm, to SBCE enabling histology and therapeutics to be carried out. SUMMARY SB endoscopy is essential in the diagnosis, management and monitoring of these multi-system conditions. Collaboration across SB centres to combine experience will help to improve the management of some of these rarer SB conditions.

Abstract
With the development of capsule endoscopy (CE) and device-assisted enteroscopy (DAE), the incidence of small-bowel tumors has increased and the characteristics of these tumors have changed. In addition, the diagnostic and therapeutic approaches for small-bowel tumors have diversified. CE is a simple, noninvasive method that aid in the visualization the entire small bowel. CE is considered the initial approach for small-bowel tumors. DAE can be used to perform endoscopic procedures such as bleeding control, polypectomy, stent insertion, and tattooing, as well as for diagnosis through visualization or tissue sampling. Therapeutic intervention with DAE is particularly useful in polyposis syndromes such as familial adenomatous polyposis and Peutz-Jeghers syndrome. This review will discuss the roles of CE and DAE in the diagnosis and treatment of small-bowel tumors.

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.

Abstract
BACKGROUND Capsule endoscopy is currently available as a noninvasive and effective diagnostic modality to identify small bowel abnormalities, with a completion rate to the cecum between 75.1 and 95.6%. A novel magnetically controlled capsule endoscopy (MCE) system could facilitate passage of the capsule through the pylorus, thereby reducing the gastric transit time (GTT). OBJECTIVE We performed this study to determine whether magnetic steering could improve the capsule endoscopy completion rate (CECR) compared to standard protocol. METHODS Patients referred for MCE in our center from June 2017 to November 2017 were prospectively enrolled. Magnetic steering of the capsule through the pylorus was performed after standard gastric examination. CECR, GTT, pyloric transit time (PTT), and rapid gastric transit (GTT ≤ 30 min) rate were compared with a historical control group enrolled from January 2017 to May 2017. RESULTS CECR was significantly higher in the intervention group (n = 107) than control group (n = 120) (100% vs. 94.2%, P = 0.02), with a significantly shorter GTT (22.2 vs. 84.5 min, P < 0.001) and PTT (4.4 vs. 56.7 min, P < 0.001). Rapid gastric transit rate in the intervention group was significantly higher than the control group (58.9% vs. 15.0%, P < 0.001). There were no statistical differences in the diagnostic yields between the two groups. CONCLUSIONS Magnetic steering of capsule endoscopy improves small bowel CECR by reducing GTT, adding further support to MCE as a practical tool for noninvasive examination of both the stomach and small bowel.

Abstract
Despite its rarity in the general population, small bowel adenocarcinoma risk is increased in individuals with hereditary colorectal cancer syndromes (HCCS). In the last decade, the advent of capsule endoscopy and device-assisted balloon enteroscopy procedures in patients with HCCS have allowed to investigate the whole small bowel, increasing the diagnostic yield of small bowel tumor. Nonetheless, there is a significant variability in the international guideline recommendations. The aim of this review is to provide an update on surveillance of small bowel in HCCS and to identify the key points for the clinical management of these patients.

Abstract
RATIONALE Gastrointestinal subepithelial tumors (SETs) with endoscopic features such as ulceration, a red color change, a peeled mucosal layer, and spontaneous bleeding could have malignant potential. However, we encountered a case of a lipoma that presented features different from the generally known features of gastrointestinal SETs. Therefore, we report an interesting rare case of a terminal ileal giant lipoma with a unique feature of spontaneous peeled ulceration on the surface on endoscopy that caused gastrointestinal bleeding. PATIENT An 82-year-old woman with a 1-week history of abdominal pain and hematochezia presented to our hospital. DIAGNOSES Ileocolonoscopy revealed a SET with a peeled surface and erythematous and ulcerative mucosal changes as well as exposed a submucosal mass at the terminal ileum. Macroscopically, the lesion appeared as a yellowish pedunculated polypoid mass measuring 3 × 2 cm with a peeled mucosal ulceration. Histopathological findings revealed a submucosal lipoma of the terminal ileum. INTERVENTION We thought that the endoscopic finding indicated malignant SETs or those with malignant potential rather than benign SETs. Therefore, the patient underwent an elective laparoscopic ileocecectomy. LESSONS We encountered a lipoma that did not present with the typical features of gastrointestinal SETs. Our findings suggest that clinicians should consider that benign SETs in the terminal ileum may present with various endoscopic findings similar to those of malignant SETs, which can cause fatal symptoms and signs.

Abstract
Background: Small bowel adenocarcinoma (SBA) is a rare malignancy that accounts for 1–2% of gastrointestinal tumours. We investigated the clinical characteristics, outcomes, and prognostic factors of primary SBA. Methods: We retrospectively analysed the characteristics and clinical courses of 205 SBA patients from 11 institutions in Japan between June 2002 and August 2013. Results: The primary tumour was in the duodenum and jejunum/ileum in 149 (72.7%) and 56 (27.3%) patients, respectively. Sixty-four patients (43.0%) with duodenal adenocarcinoma were asymptomatic and most cases were detected by oesophagogastroduodenoscopy (EGD), which was not specifically performed for the detection or surveillance of duodenal tumours. In contrast, 47 patients (83.9%) with jejunoileal carcinoma were symptomatic. The 3-year survival rate for stage 0/I, II, III, and IV cancers was 93.4%, 73.1%, 50.9%, and 15.1%, respectively. Multivariate analysis revealed performance status 3–4, high carcinoembryonic antigen, high lactate dehydrogenase (LDH), low albumin, symptomatic at diagnosis, and stage III/IV disease were independent factors for overall survival (OS). Ten patients (18.5%) with stage IV disease were treated with a combination of resection of primary tumour, local treatment of metastasis, and chemotherapy; this group had a median OS of 36.9 months. Conclusions: Although most SBA patients were diagnosed with symptomatic, advanced stage disease, some patients with duodenal carcinoma were detected in early stage by EGD. High LDH and symptomatic at diagnosis were identified as novel independent prognostic factors for OS. The prognosis of advanced SBA was poor, but combined modality therapy with local treatment of metastasis might prolong patient survival.

Abstract
PURPOSE OF REVIEW The breakthrough success of capsule endoscopy and device-assisted enteroscopy has inspired researchers to test and push the boundary of these technologies. The authors herein summarize the latest and most significant studies with clinical impact. RECENT FINDINGS Competing capsule endoscopy models have enriched the platform of this wireless device. The role of capsule endoscopy in Crohn's disease is expanding as we learn more of the significance of disease distribution and response to treatment. The benefit of capsule endoscopy in abdominal pain has previously been sceptical, but may have a role. Device-assisted enteroscopy demonstrates significant benefit in the management of patients with Crohn's disease and Peutz-Jeghers syndrome. On the contrary, long-term data suggest that endotherapy to small bowel angioectasia may not be as beneficial to patients as we once thought. The role of device-assisted enteroscopy in novel territory, including coeliac disease and endoscopic retrograde cholangiopancreatography, continues to be tested. SUMMARY The limit of capsule endoscopy and enteroscopy is yet to be reached. Accumulating long-term data alludes to the benefits of our current practice while spawning novel indications for small bowel endoscopy.
