Capsule endoscopy: Do we still need it after 24 years of clinical use?

In this letter, we comment on a recent article published in the World Journal of Gastroenterology by Xiao et al, where the authors aimed to use a deep learning model to automatically detect gastrointestinal lesions during capsule endoscopy (CE). CE was first presented in 2000 and was approved by the Food and Drug Administration in 2001. The indications of CE overlap with those of regular diagnostic endoscopy. However, in clinical practice, CE is usually used to detect lesions in areas inaccessible to standard endoscopies or in cases of bleeding that might be missed during conventional endoscopy. Since the emergence of CE, many physiological and technical challenges have been faced and addressed. In this letter, we summarize the current challenges and briefly mention the proposed methods to overcome these challenges to answer a central question: Do we still need CE?

Clinical assessment of small bowel capsule endoscopy in pediatric patients

Introduction

Small bowel capsule endoscopy is a first-line examination method for small bowel diseases, which can find small intestinal lumen and mucosal lesions.

Methods

We retrospectively assessed patients who underwent small bowel capsule endoscopy between September 2020 and May 2023 to examine their clinical and small bowel capsule endoscopic data, aiming to provide insights into the application of this technique in pediatric patients with small intestinal diseases.

Results

All instances of capsule retention were successfully resolved through enteroscopy. Of the 1140 children who completed the capsule endoscopy, 97.46% (1111/1140) underwent a comprehensive examination of the entire small intestine without experiencing any discomfort. Capsule endoscopy yielded abnormal findings in 672 cases, with a positive detection rate of 58.95%. Among the positive results, intestinal mucosal inflammatory lesions were the most prevalent, occurring in 292 cases (43.45%), followed by ulcerative or erosive lesions in 236 cases (35.12%), diverticulum in 54 cases (8.04%), and vascular lesions in 30 cases (4.46%). Lymphangiectasis was observed in 16 cases (2.38%). The distribution of positive lesions did not exhibit significant gender-based differences, but there were variations among different age groups. Among all children who completed the small bowel capsule endoscopy, the most frequently reported symptom was abdominal pain (815/1140 cases, 71.49%), followed by 130 cases (11.40%) of bloody stools or melena.

Discussion

Small bowel capsule endoscopy is well-tolerated and safe in children, carrying significant clinical importance for diagnosing abdominal pain and obscure gastrointestinal bleeding in pediatric patients.

Prospective, multicenter, self-controlled clinical trial on the effectiveness and safety of a cable-transmission magnetically controlled capsule endoscopy system for the examination of upper GI diseases

BACKGROUND AND AIMS

Many GI disorders and precancerous conditions often present asymptomatically, leading to delayed patient diagnoses and treatment interventions. In this study, we developed a novel cable-transmission magnetically controlled capsule endoscopy (CT-MCCE) system for detecting GI diseases and assessed its safety and feasibility through clinical trials.

METHODS

This prospective, multicenter trial compared CT-MCCE with conventional gastroscopy in patients aged 18 to 75 years with upper GI tract diseases between October 2022 and July 2023. The primary endpoints were the evaluation of sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) in the detection of focal lesions within the esophagus, stomach, and duodenal bulb using CT-MCCE.

RESULTS

One hundred eighty individuals (mean age, 43.1 years; 52.22% women) were recruited from 3 hospitals in China. CT-MCCE detected lesions in the esophagus with a sensitivity of 97.22%, specificity of 100%, PPV of 100%, NPV of 98.18%, and accuracy of 98.89%; detected gastric focal lesions in the entire stomach with a sensitivity of 96.81%, specificity of 98.84%, PPV of 98.91%, NPV of 96.59%, and accuracy of 97.78%; and detected lesions in the duodenal bulb with a sensitivity of 100%, specificity of 100%, PPV of 100%, NPV of 100%, and accuracy of 100%. There were no significant differences between CT-MCCE and EGD regarding the cleanliness of the upper GI tract and visibility of the upper GI mucosa. However, CT-MCCE was associated with a lower incidence of discomfort than EGD (P < .001).

CONCLUSIONS

The diagnostic performance of CT-MCCE is comparable with that of EGD in the completion of upper GI tract examinations and lesion detection. Furthermore, the improved tolerance of CT-MCCE in detecting upper GI diseases was noted without any observed adverse events. (Clinical trial registration number: ChiCTR2200063630.).

Clinical application and feasibility of capsule endoscopy in children at a medical center in central Taiwan

BACKGROUND PURPOSE

Capsule endoscopy (CE) is a noninvasive examination for excellent visualization of small bowel mucosal lesions. We aimed to evaluate the clinical efficacy and safety of CE in pediatric patients.

METHODS

From April 2014 to December 2022, CE procedures performed in children younger than 18 years of age at Taichung Veteran General Hospital were analyzed retrospectively.

RESULTS

Among 136 procedures, the completion rate was 95.6% (n = 130), with a median age of 14 years old. Suspicion or evaluation of inflammatory bowel diseases (IBD) (41%) was the most common indication for CE. Other common indications of CE were chronic unexplained abdominal pain (35%) and obscure gastrointestinal bleeding or iron deficiency anemia (21%). No procedure-related complications occurred. The diagnosis of those patients with incomplete study were CD with small bowel stricture, graft-versus-host disease and duodenal ulcers. A total of 86 CE procedures showed positive findings, and the overall diagnostic yield rate was 63.2%. Small bowel ulcers (65.12%) were the most common findings. Overall, 26.5% of CE examinations resulted in a new diagnosis and 44.9% of CE exams led to a change in therapy. For patients with IBD, CE findings resulted in an even higher therapeutic change rate of 48.1%.

CONCLUSIONS

CE is a safe and feasible diagnostic method to study the small intestine in children, especially for IBD. Incomplete study could be an indicator of positive finding and can potentially be a guide to identify the site of possible strictures.

Small-sized versus standard magnetic capsule endoscopy in adults: a two-center, double-blinded randomized controlled trial

BACKGROUND : Certain patients experience difficulty swallowing a video capsule endoscopy (VCE) device owing to its relatively large size. The newly developed small-sized magnetically controlled capsule endoscopy (MCE) device is the smallest VCE device ever reported. We aimed to evaluate the performance of the small-sized MCE device in terms of ingestion and examination efficacy. METHODS : Patients in two centers were prospectively enrolled and randomized to the small-sized or standard MCE groups. Differences in capsule ingestion difficulties, visualization of the gastrointestinal tract, and capsule transit times were compared. RESULTS : 96 patients were enrolled (48 in each group). In the small-sized MCE group, the mean (SD) difficulty score and time to swallow the capsule, and success rate for swallowing the capsule at the first attempt were 0.6 (1.0), 3.4 (1.3) seconds, and 89.6 %, which was significant better compared with the standard MCE group with 3.1 (1.7), 12.0 (14.3) seconds and 60.4 %, respectively (all P < 0.001). Visualization of the esophagus, stomach, and small bowel were comparable between the two groups. The small-sized MCE group had a significantly shorter gastric transit time (49.4 minutes vs. 66.2 minutes; P = 0.04) and longer small-bowel transit time (5.8 hours vs. 5.0 hours; P = 0.045). CONCLUSIONS : The small-sized MCE device is feasible and safe for gastrointestinal examination, alleviating difficulties in capsule ingestion, improving gastric emptying under magnetic control, and prolonging the small-bowel transit time.

Safety and efficacy of the endoscopic delivery of capsule endoscopes in adult and pediatric patients: Multicenter Japanese study (AdvanCE-J study)

BACKGROUND AND AIM

We retrospectively determined the safety and efficacy of the endoscopic delivery (ED) of capsule endoscopes.

METHODS

We enrolled 10,156 patients who underwent small bowel capsule endoscopy (SBCE), 3182 who underwent patency capsule (PC), and 1367 who underwent colon capsule endoscopy (CCE), at 11 gastroenterological and nine pediatric centers.

RESULTS

Small bowel capsule endoscopies, PCs, and CCEs were endoscopically delivered to 546 (5.4%), 214 (6.7%), and 14 (1.0%) patients, respectively. Only mild complications occurred for 21.6% (167/774), including uneventful mucosal damage, bleeding, and abdominal pain. Successful ED of SBCE to the duodenum or jejunum occurred in 91.8% and 90.7% of patients aged <16 years and ≥16 years, respectively (P = 0.6661), but the total enteroscopy rate was higher in the first group (91.7%) than in the second (76.2%, P < 0.0001), for whom impossible ingestion (87.3%) was significantly more common than prolonged lodging in the stomach (64.2%, P = 0.0010). Successful PC and CCE delivery to the duodenum occurred in 84.1% and 28.6%, thereafter the patency confirmation rate and total colonoscopy rate was 100% and 61.5%, respectively. The height, weight, and age cutoff points in predicting spontaneous ingestion were 132 cm, 24.8 kg, and 9 years 2 months, respectively, in patients aged <16 years. Patients aged ≥16 years could not swallow the SBCEs mainly due to dysphagia (75.0%); those who retained it in the esophagus due to cardiac disease (28.6%), etc. and in the stomach due to diabetes mellitus (15.7%), etc. CONCLUSIONS: This large-scale study supports the safety and efficacy of ED in adult and pediatric patients.

Indications and Limitations Associated with the Patency Capsule Prior to Capsule Endoscopy

The retention of the capsule used during small bowel capsule endoscopy (SBCE) is a serious complication that can occur in patients with known or suspected small bowel stenosis, and a prior evaluation of the patency of the gastrointestinal (GI) tract is therefore essential. Patency capsule (PC) is a non-diagnostic capsule the same size as the diagnostic SBCE. To date, there are no clear guidelines regarding the contraindications for undergoing a PC evaluation prior to SBCE. Each small bowel disorder has specific occasions to inhibit the progress of PC and SBCE, even though they do not have any stenotic symptoms or abnormalities on imaging. In this review, we summarize the indications and limitations of PC prior to SBCE, especially the contraindications, and discuss clinical scenarios in which even PC should be avoided, and therefore such areas of stenosis should be evaluated by alternative modalities. We thus propose this new algorithm to evaluate the patency of the GI tract for patients with suspected and known small bowel stenosis in order that they may undergo SBCE safely.

Usefulness of ultrasonography for small intestinal evaluations in pediatric Crohn's disease

BACKGROUND

Small bowel capsule endoscopy (SBCE) for Crohn's disease is useful; however, its use has some limitations, such as invasiveness when endoscopic assistance is required in patients who cannot swallow the capsule, and the burden of interpretation on a physician. In contrast, intestinal ultrasonography (IUS) is a non-invasive modality for children. The purpose of this study is to evaluate the accuracy of IUS for pediatric patients with established Crohn's disease.

METHODS

Small bowel capsule endoscopy and IUS findings from the same period in pediatric patients with established Crohn's disease were analyzed retrospectively. First, we compared the Lewis score (LS), small bowel endoscopic activity, and IUS findings by small bowel wall thickness (SBWT) and mesenteric lymph node size (MLNS). Second, we compared the performance of IUS findings with those of some biomarkers.

RESULTS

In 22 procedures, SBWT and MLNS were correlated with LS (r = 0.52, P < 0.05, and r = 0.45, P < 0.05, respectively). Small bowel wall thickness, erythrocyte sedimentation rate, and fecal calprotectin levels had the highest accuracy (81.8%, 81.8%, and 81.8%, respectively). The combination of SBWT and MLNS had the highest positive predictive value and negative predictive value (100% and 83.3%, respectively).

CONCLUSIONS

Intestinal ultrasonography findings, including SBWT and MLNS, are useful for monitoring small bowel lesions in pediatric patients with established Crohn's disease. We suggest first evaluating small bowel inflammation by IUS in pediatric patients with Crohn's disease before SBCE because IUS is less invasive than SBCE.

Capsule Endoscopy in Children

Since its clearance for use throughout the world, capsule endoscopy (CE) has become an important diagnostic tool, helping us to understand and document both normal and abnormal findings in the small intestine, especially in children, since CE usually can be employed without sedation or radiation. The indications in children and adults are similar, though their relative frequencies are different, with evaluation of potential and known inflammatory bowel disease the most common in the pediatric population, with CE also yielding increased diagnostic certainty compared to radiographic studies and surrogate biomarkers. Newer capsules now create opportunities to expand that understanding and our practices so that we can learn when and how to employ CE and pan-enteric CE to better monitor and guide therapy. It will take further studies to determine the best uses for CE and how to select the appropriate candidates, especially with ongoing concern about capsule ingestion vs. placement, the potential for capsule retention (particularly in known Crohn's disease), still elusive optimal methods for bowel cleansing, and the most meaningful scoring for research and clinical use.

The characteristics of video capsule endoscopy in pediatric Henoch-Schönlein purpura with gastrointestinal symptoms

BACKGROUND

Henoch-Schönlein purpura (HSP) is a systemic small-vessel vasculitis also named IgA vasculitis that commonly affects the gastrointestinal tract. The video capsule endoscopy (VCE) characteristics of pediatric HSP patients are rarely reported.

METHODS

Patients diagnosed with HSP and analyzed by VCE examination at our hospital from February 2010 to January 2019 are enrolled. The clinical features, laboratory findings, and the characteristics of VCE findings are studied.

RESULTS

There are 30 patients enrolled in this investigation from February 2010 to January 2020. The mean age of these patients is 96.9 ± 35.8 months, and the most frequent finding of VCE is mucosal erosion, which account for 79.3% of the patients, and followed by mucosal erythema or petechia accounted for 69% of the patients. Regarding the disease location detected by endoscopy, jejunum is the most common involved part of the gastrointestinal tract in pediatric HSP patients. All the patients had the jejunum involved except in one patient the VCE did not pass through the pylorus. One third of the patients involved the descending portion of duodenum. No side effect is observed in this study.

CONCLUSIONS

VCE may be an excellent adjust tool for evaluation of the gastrointestinal tract in children with abdominal symptoms without typical purpura in suspected pediatric HSP patients. VCE appears to be superior to esophagogastroduodenoscopy in detecting small intestinal lesions of HSP and has an excellent safety profile.

[Value of capsule endoscopy in children with small intestinal diseases with hematochezia as the chief complaint]

OBJECTIVE

To evaluate the value of capsule endoscopy in children with small intestinal diseases with hematochezia as the chief complaint.

METHODS

A retrospective analysis was performed on the clinical data and capsule endoscopy findings of 93 children with hematochezia who were admitted to Children's Hospital of Fudan University from May 2015 to January 2019 and underwent capsule endoscopy. According to the capsule endoscopy findings of the jejunum and the ileum, they were divided into a positive lesion group with 39 patients and a negative lesion group with 54 patients. Related clinical data and the features of lesion on capsule endoscopy were analyzed for the two groups.

RESULTS

There were no significant differences in age, sex, duration of capsule endoscopy, gastric transit time, and small intestinal transit time between the positive lesion and negative lesion groups (P>0.05). The positive lesion group had a significantly lower level of hemoglobin than the negative lesion group (P<0.05). Hemoglobin level was negatively correlated with the rate of positive lesions on capsule endoscopy (r=-0.342, P=0.001). Among the 39 patients with positive lesions on capsule endoscopy, the detection of Meckel's diverticulum was the highest (41%), followed by inflammatory bowel disease (21%).

CONCLUSIONS

Capsule endoscopy has a certain value in detecting small intestinal diseases, especially diseases in the jejunum and the ileum, in children with lower gastrointestinal hemorrhage.

Performance measures for small-bowel endoscopy: A European Society of Gastrointestinal Endoscopy (ESGE) Quality Improvement Initiative

The European Society of Gastrointestinal Endoscopy (ESGE) together with the United European Gastroenterology (UEG) recently developed a short list of performance measures for small-bowel endoscopy (i.e. small-bowel capsule endoscopy and device-assisted enteroscopy) with the final goal of providing endoscopy services across Europe with a tool for quality improvement. Six key performance measures both for small-bowel capsule endoscopy and for device-assisted enteroscopy were selected for inclusion, with the intention being that practice at both a service and endoscopist level should be evaluated against them. Other performance measures were considered to be less relevant, based on an assessment of their overall importance, scientific acceptability, and feasibility. Unlike lower and upper gastrointestinal endoscopy, for which performance measures had already been identified, this is the first time small-bowel endoscopy quality measures have been proposed.

Extremely young case of small bowel intussusception due to Peutz-Jeghers syndrome with nonsense mutation of STK11

Intussusception is a frequent and severe complication of Peutz-Jeghers syndrome (PJS). We herein present the case of a 3-year-old girl who experienced jejuno-jejunal intussusception due to PJS polyps. Despite no apparent family history of PJS, she had exhibited mucocutaneous pigmentation since infancy and recurrent abdominal pain and vomiting from 2 years of age. Segmental resection of the jejunum during emergency laparotomy for the intussusception revealed multiple hamartomatous polyps. Genetic analysis uncovered a germline nonsense mutation of c.247A>T in exon 1 of serine/threonine kinase 11 (STK11). Biannual follow-up surveillance for polyps by esophagogastroduodenoscopy, colonoscopy, and small bowel capsule endoscopy is ongoing. Reports describing the clinical and genetic features of extremely young PJS with intussusceptions are rare, although a literature review of STK11 germline mutations revealed several other pediatric cases of complicating intussusception at ≤ 8 years old. Considering the recent advances in surveillance and treatment options for the small bowel, earlier management of symptomatic children with PJS may be warranted to avoid surgical emergency.

Applications of wireless capsule endoscopy in pediatric age: an update

Background: The small bowel has often been considered the mysterious “black hole” of the gastrointestinal tract. With regards to this, the development of the wireless capsule endoscopy (WCE) has represented a turning point. It is a non-invasive technique, enabling an excellent visualization of the small bowel (SB) mucosa without the use of radiation. The WCE was approved by the Food and Drug Administration (FDA) in 2001 for adults and in 2004 for children. The aim of the present review is to provide an update on indications, diagnostic yield, safety and limitations of WCE in children. Even though literature regarding the use of WCE in pediatric age is more limited than in adults,WCE is a useful and safe diagnostic tool for the exploration of the small bowel also in children. The indications for WCE are similar at any age, however the main indication in children is Crohn’s disease (CD), while in the adults is the research of SB bleeding. The main limitation in pediatric age is the possibility for younger children to swallow the capsule. WCE in pediatric is a rapidly advancing technology and has the potential to further transform the evaluation and management of SB disease. (www.actabiomedica.it)

Correlation of the endoscopic findings for small and large bowels in pediatric patients with established Crohn's disease

Small bowel capsule endoscopy can detect subtle mucosal lesions in pediatric patients with Crohn’s disease, and our aim was to evaluate its application in established ileocolonic Crohn’s disease. Colonic inflammation was evaluated with the colonic Simple Endoscopic Score for Crohn’s Disease (SES-CD) (excluding the score of the terminal ileum). Small bowel inflammation was evaluated with the Lewis score and/or Capsule Endoscopy Crohn’s Disease Activity Index (CECDAI). A Lewis score <135 was defined as small bowel inactive. A colonic SES-CD of 0 (colonic inactive group) was observed in 22/42 procedures (52.4%), and active small bowel lesions were observed in 11/22 procedures (50.0%). The Lewis score was lower in the colonic inactive group compared to the colonic active group. Correlations between the colonic SES-CD, the Lewis score and CECDAI were weak. The Lewis score and CECDAI in the colonic inactive group had significant correlation with fecal calprotectin levels. We suggest that Crohn’s disease patients without both colonic active lesions and elevation of fecal calprotectin levels may not need to receive small bowel capsule endoscopy due to low incidence of lesions in small bowel.

Clinical Use of Patency Capsule: A Comprehensive Review of the Literature

The patency capsule is a radiopaque, dissolvable diagnostic tool, similar in shape and size to small bowel capsule endoscopes. It was developed to offer a simple, safe, efficient, and accurate evaluation of small bowel functional patency. Although unable to provide direct visual information regarding the presence and location of strictures, masses, or luminal narrowing of the small bowel, a successful patency test minimizes the risk of retention and allows the safe administration of a capsule endoscope. However, its use entails a low risk of potentially harmful adverse events, which in their majority are indolent and resolve spontaneously. Abdominal pain and symptomatic retention are accountable for the majority of reported adverse events, whereas a limited number of reports describe life-threatening complications, namely intestinal obstruction, perforation, and intestinal ischemia. Computed tomography is the modality of choice for the identification of the exact position of an impacted patency capsule, whilst the use of plain abdominal radiographs should be avoided for the evaluation of the patency capsule position, as they provide false information. Hereby, we present a comprehensive review of the available literature regarding the characteristics, indications, clinical use, effectiveness, and adverse events of the patency capsule.10.1093/ibd/izy152_video1izy152.video15777752348001.

Magnetic-Guided Capsule Endoscopy in the Diagnosis of Gastrointestinal Diseases in Minors

Objective

This study aimed at investigating the clinical value of magnetic-guided capsule endoscopy (MGCE) in the diagnosis of gastrointestinal diseases in minors.

Methods

Eighty-four minor patients hospitalized in the pediatric department at Ruijin Hospital between June 2015 and January 2018 were enrolled for this study. Following bowel preparation, all patients underwent MGCE. The feasibility, safety, diagnostic yield, and sensitivity of MGCE were analyzed. Patients were followed up for more than 2 weeks.

Results

The main indications for MGCE in minors were Crohn's disease, gastrointestinal bleeding, and abdominal pain. The main causes of gastric disease were gastric inflammatory hyperplasia, exudative gastritis, and polyps. The most common small bowel diseases in minors were Crohn's disease, Henoch-Schonlein purpura, and polyps. The diagnostic yield in the stomach and small intestine was 13.1% and 28.6%, respectively, and the sensitivity was 100% and 96.0%, respectively. No adverse events occurred.

Conclusion

MGCE is a safe, effective, and well-tolerated procedure with good sensitivity and has a potential clinic value for the diagnosis of gastrointestinal diseases in minors.

Ileal tubular adenoma as a cause of lower gastrointestinal bleeding in infants

Lower gastrointestinal bleeding is a common pathology with diverse causes depending on the patients´ age. The most common causes in adults are polyps, neoplasias, diverticular disease and angiodysplasia. In neonates, necrotizing enterocolitis and volvulus, and anal fissures and bowel intussusception in infants. Polyps are reported as a cause of bleeding only in children of preschool age.

Relationships of capsule endoscopy Lewis score with clinical disease activity indices, C-reactive protein, and small bowel transit time in pediatric and adult patients with small bowel Crohn's disease

Relationships between the capsule endoscopy Lewis score (LS) and clinical disease activity indices and C-reactive protein (CRP) are controversial in adult patients with Crohn's disease (CD). Also, data on pediatric patients are relatively less. However, correlation between LS and small bowel transit time (SBTT) remains investigational. The aim of the present study was to explore the correlations between LS and clinical disease activity indices, CRP, SBTT in pediatric, and adult patients with small bowel CD.Retrospective, single-center study on consecutive inpatients with established small bowel CD was conducted. The clinical disease activity index was determined using the abbreviated Pediatric Crohn's Disease Activity Index (aPCDAI) in patients aged <18 years and the Harvey-Bradshaw Simple Index (HBI) in adults. Spearman's rank correlation coefficient was used to assess the correlations of LS with aPCDAI, HBI, CRP, and SBTT, respectively.150 patients were enrolled (30 children and adolescents). In pediatric patients, correlations between LS and aPCDAI, CRP were moderate (r1 = 0.413; r2 = 0.379; P1 = .023; P2 = .044). There was no correlation between LS and SBTT (r = -0.029; P = .88). In adults, weak correlations were found between LS and HBI, SBTT (r1 = 0.213; r2 = 0.237; P1 = .019; P2 = .009). Correlation between LS and CRP was moderate (r = 0.326; P < .001). Strong correlations were found between CRP and HBI, aPCDAI (r1 = 0.522; r2 = 0.650; P < .001). The follow-up patients were all in clinical remission after treatment within 4 months, whereas only a minority reached mucosal healing. HBI, aPCDAI, CRP, and LS in all patients were reduced after treatment, whereas difference in CRP in pediatric patients and difference in LS in adults between baseline and follow-up were not found to be statistically significant. Also, the average SBTT at baseline was not found to be different from that at follow-up in all patients.The role of capsule endoscopy should be emphasized both in pediatric and adult patients with small bowel CD. Furthermore, the small bowel transit time may not be affected by the grade of small intestinal inflammation.

Retained Wireless Capsule Endoscope in a Girl with suspected Crohn's Disease

Wireless capsule endoscopy (WCE) is one of the great milestones in the field of gastroenterology. It is versatile in image acquisition, painless and can reach parts of the small bowel not amenable to conventional endoscopy. The commonest complication with WCE is retention of the capsule. We report a case of retained capsule in a child who was being investigated for obscure gastrointestinal bleeding (OGIB). Operative intervention was required for its retrieval after two weeks of expectant management.
