Double balloon enteroscopy in the old: Experience from China

The Diagnostic Yields and Safety of Double-Balloon Enteroscopy in Obscure Gastrointestinal Bleeding and Incomplete Small Bowel Obstruction: Comparison between the Adults and Elderly

Background

Double-balloon enteroscopy (DBE) is widely used worldwide. However, comparisons between the diagnostic yields in adults and the elderly remain scarce.

Aim

The aim of this study is to compare the diagnostic yields and safety of DBE between adults and elderly with obscure gastrointestinal bleeding and incomplete small bowel obstruction.

Method

We retrospectively reviewed patients who underwent DBE with indication of obscure gastrointestinal bleeding or incomplete small bowel obstruction in Ruijin Hospital and classified them into adults (18–64 years old) and elderly (≥65 years old). Clinical characteristics, diagnostic yields, and postoperative complications were collected and further analyzed.

Results

A total of 877 DBE procedures, 729 in adults and 148 in the elderly, were performed. In the patients with OGIB, the adults showed a higher frequency of Meckel's diverticulum compared with the elderly (4.6% vs. 0.9%, P = 0.032). Angioectasia was higher in frequency in the elderly than in the adults (25.9% vs. 17.9%, P = 0.048). In patients with incomplete small bowel obstruction, the elderly were more likely to have adenocarcinoma than the adults (19.4% vs. 7.1%, P = 0.038). The adults had higher tendency to have Crohn's disease than the elderly (23.4% vs. 8.3%, P = 0.045). Most of the postoperative complications were mild. The adults and elderly displayed comparable tolerance to DBE (P > 0.05)

Conclusion

DBE has a high diagnostic yield in small bowel disorders, and a slight difference in disease spectrum was observed between the adults and elderly. DBE can be well-tolerated in the elderly.

Device-assisted enteroscopy: An update on techniques, clinical indications and safety

After more than 15 years since its introduction into clinical practice, indications for device-assisted enteroscopy have greatly expanded. Alongside the consolidated indications such as the diagnosis and treatment of small bowel bleeding, Crohn's disease, hereditary polyposis, small-bowel tumors and complicated celiac disease, device-assisted enteroscopy is nowadays largely used to perform endoscopic retrograde cholangiopancreatography in patients with altered anatomy, stent placement, retrieval of foreign bodies, direct insertion of jejunal feeding tubes, and in selected cases of incomplete colonoscopy. This has been made possible by the technical improvements of the enteroscopes and accessories and by the widespread use of the method. Device-assisted enteroscopy endotherapy currently offers a safe and effective alternative to major surgery and often represents the preferred option for treatment of small-bowel pathology. Its safety profile is favourable even in the elderly patient, provided that it is performed in high-volume and experienced centers. The evolution of the enteroscopy technique is a challenge for the future and could be facilitated by the new enteroscopes models. These prototypes need a thorough clinical and safety assessment especially for the complex therapeutic procedures. Large prospective, multicenter studies should be performed to assess whether the use of device-assisted enteroscopy leads to improved patients' long-term outcomes.

Enteroscopy in the Elderly: Review of Procedural Aspects, Indications, Yield, and Safety

Background

As human longevity continues to increase, age-related diseases are more common, which leads to a higher use of gastroenterology services. Endoscopic procedures are generally considered to be of higher risk in the elderly with multiple comorbidities. However, some endoscopic techniques have already been proved to be well tolerated in the elderly.

Summary

<underline></underline>Enteroscopy enables the nonsurgical diagnosis and therapeutic management of a wide variety of small bowel diseases. Although it has been shown to be safe and effective, with high diagnostic yield and therapeutic success rate in the general population, its safety and efficacy in the elderly is largely unknown, and there are still some concerns about its use in these patients.

Key Messages

This review will focus on enteroscopy in elderly people, taking into account patient and procedure characteristics, indications, findings, yield, and complication rate.

The use of single balloon enteroscopy in Crohn's disease and its impact on clinical outcome

OBJECTIVES

Single balloon enteroscopy (SBE) is an effective and safe modality for the diagnosis and therapeutic intervention of small bowel disorders. Its use in patients with Crohn's disease (CD) and particularly its effect on management changes in CD have not yet been determined.

MATERIALS AND METHODS

We performed a retrospective review of the endoscopic and clinical data available on a cohort of patients with small bowel CD who had undergone SBE to determine the diagnostic and therapeutic yield of the procedure and the initial and longer-term impact it had on clinical management.

RESULTS

About 52 patients have undergone SBE in our unit for the investigation of known (n = 39) or suspected (n = 13) small bowel CD with a diagnostic yield of 77% and 39%, respectively. SBE had an immediate clinical impact in 69% (n = 33) of patients, including dilatation of a stricture in 27% (n = 13), initiation or adjustment of dose of medications in 48% (n = 23), referral for surgical resection in 6% (n = 3). Moreover, the procedure permitted determining a new diagnosis of CD in 8% of the patients (n = 4), and excluding it in 8% (n = 4). Longer term follow-up was available in 34 patients (65%) which showed a significant difference in mean HBI score from 6.6 before the procedure to 4.2 after it (p < .0001).

CONCLUSIONS

SBE has a high diagnostic and therapeutic yield in CD and significantly impacts disease management. Careful patient selection is a key factor in optimizing its use in CD.

Paradigm shift: should the elderly undergo propofol sedation for DBE? A prospective cohort study

OBJECTIVE

Evaluate the safety of propofol-assisted double balloon enteroscopy (DBE) in elderly patients against a younger cohort.

DESIGN

Prospective cohort study.

SETTING

All patients undergoing DBE over a 30-month period were recruited at our tertiary centre.

PATIENTS

215 procedures in 161 patients were performed. An age cut-off of 65 years and above was used to define those who were elderly.

INTERVENTIONS

Patients were subcategorised into four groups: elderly or young undergoing DBE with propofol or conventional sedation (with midazolam±fentanyl).

MAIN OUTCOME MEASURES

Patient demographics, comorbidities, procedural data, complications, diagnostic and therapeutic yield were compared.

RESULTS

Cardiovascular disease and a higher American Society of Anaethesiologists (ASA) status were more prevalent in elderly patients undergoing DBE with propofol (p<0.05). Common indications for DBE were occult and overt obscure gastrointestinal bleeding and suspected Crohn's disease (elderly vs young: 50.7% vs 42.3%, 17.8% vs 12% and 19.2% vs 26.1%, respectively). Diagnostic yield was higher in elderly compared with young patients (75.3% vs 58.5%, p=0.016). The most common findings in elderly and young patients were angioectasia (30.1% and. 18.3%, respectively) and ulcers (17.8% and 9.2%, respectively), while therapeutic intervention rates were comparable (42.5% vs 32.4%, p=0.18). ASA status did not affect propofol dose (p=0.55) or procedure duration (p=0.31). Tolerance scores were favourable in those receiving propofol compared with conventional sedation (p<0.05). There was no difference in complications between the four groups (p=0.17).

CONCLUSION

Compared with young patients, propofol-assisted DBE in the elderly is safe and has a high diagnostic yield.

Background:

The double balloon enteroscopy is an important method for the endoscopic approach of the small bowel that provides diagnosis and therapy of this segment’s disorders, with low complication rate.

Aim:

Analysis of patients undergoing double balloon enteroscopy. The specific objectives were to establish the indications for this method, evaluate the findings by the double balloon enteroscopy, analyze the therapeutic options and the complications of the procedure.

Methods:

It is a retrospective analysis of 65 patients who underwent double balloon enteroscopy.

Results:

Sixty-five procedures were performed in 50 patients, 63.1% were women and 36.9% were men. The mean age was 50.94 years. The main indication it was gastrointestinal bleeding, followed by abdominal pain and Crohn’s disease. Most procedures were considered normal. Polyps were the most prevalent finding, followed by angioectasias and duodenitis. In 49.2% of the cases, one or more therapeutic procedures were performed, (biopsy was the most prevalent). There was only one case of acute pancreatitis, which was treated clinically.

Conclusion:

The enteroscopy is good and safe method for the evaluation of the small bowel, and its main indications are gastrointestinal bleeding and abdominal pain. It has low complications rates and reduces the necessity of surgery.

Double-balloon enteroscopy and outcomes in patients older than 80

BACKGROUND

double-balloon enteroscopy (DBE) is becoming more commonly used for investigation of small bowel pathology. Currently, there are limited data to describe its safety and efficacy in the population over age 65.

AIM

to investigate the indications, findings and outcomes of DBE performed in patients older than 80, as well as the correlation between DBE and prior capsule endoscopy (CE) findings.

METHODS

we retrospectively reviewed our large DBE database, including procedures from January 2006 to September 2012. Patients aged 80 or older at the time of DBE were included in the study. The indications, findings, outcomes and diagnostic yield of DBE were calculated by frequency analysis.

RESULTS

two hundred and fifteen DBEs were performed in 130 patients aged 80 or older. The mean age was 83.6 ± 3.03 years (range: 80-94). Twelve patients (9.2%) were assigned an American Society of Anaesthesiologists score of II prior to procedure, 102 patients (78.4%) were assigned a score of III and 16 patients (12.3%) were given a score of IV. The most common indication for DBE was obscure gastrointestinal bleeding (N = 204, 94.9%). One hundred and fourteen patients (87.7%) underwent CE prior to DBE, and correlation between findings of CE and DBE occurred in 74.6% of these patients. The overall diagnostic yield of DBE was 77.2% (N = 166). There were no immediate post-procedural complications or failed procedures.

CONCLUSION

DBE is a safe and effective technique for investigation of the small bowel in patients aged 80 and older. Age alone should not be a contraindication to performing DBE when clinically indicated.

Deep enteroscopy - indications, diagnostic yield and complications

Since its introduction in 2001 capsule endoscopy opened up the small bowel for diagnostic approaches followed by double balloon enteroscopy which enabled the endoscopic community to perform therapeutic interventions in the whole small intestine. In this review the scientific developments related to indications, diagnostic yield and complications of the last years between the competing devices double ballon enteroscopy, single balloon enteroscopy and spiral enteroscopy are illustrated.

Double-balloon enteroscopy in elderly patients: is it safe and useful?

Background/Aims

Providers may be hesitant to perform double-balloon enteroscopy (DBE) in the elderly because the increased number of co-morbidities in this population poses a greater risk of complications resulting from sedation. There are limited data on the use of DBE in the elderly. Here, we assessed the safety and efficacy of DBE in the elderly compared to those in younger patients.

Methods

We retrospectively analyzed the medical records of 158 patients who underwent 218 DBEs. Patients were divided into an elderly group (age ≥65 years; mean 71.4±5.4; n=34; 41 DBEs) and a younger group (age <65 years; mean 39.5±13.5; n=124; 177 DBEs).

Results

In both groups, the most common indication for DBE was obscure gastrointestinal bleeding. Mucosal lesions (33.3% vs. 60.9%; P=0.002) were the most common finding in both groups, followed by tumors (30.8% vs. 14.1%; P=0.036). The elderly were more likely to receive interventional therapy (51.3% vs. 23.5%; P=0.001). The diagnostic yield of DBE was slightly higher in the elderly group (92.3% vs. 86.5%; P=0.422), but was not statistically significant. The therapeutic success rate of DBE was 100% in the elderly group compared to 87.5% in the younger group (P=0.536). The overall DBE complication rate was 1.8% overall, and this rate did not differ significantly between the groups (2.6% vs. 1.7%; P=0.548).

Conclusions

DBE is safe and effective in the elderly, and has a high diagnostic yield and high therapeutic success rate.

Comparison of double balloon enteroscopy in adults and children

AIM: To compare results of double balloon enteroscopy (DBE) procedures in pediatric and adult patients.

METHODS: The medical files of patients who underwent DBE at Gazi University School of Medicine, Ankara, Turkey between 2009 and 2011 were examined retrospectively. Adult and pediatric patients were compared according to DBE indications, procedure duration, final diagnosis, and complications. DBE procedures were performed in an operating room under general anesthesia by two endoscopists. An oral or anal approach was preferred according to estimated lesion sites. Overnight fasting of at least 6 h prior to the start of the procedure was adequate for preprocedural preparation of oral DBE procedures. Bowel cleansing was performed by oral administration of sennosides A and B solution, 2 mL/kg, and anal saline laxative enema. The patients were followed up for 2 h after the procedure in terms of possible complications.

RESULTS: DBE was performed in 35 patients (5 pediatric and 30 adult). DBE procedures were performed for abdominal pain, chronic diarrhea, bleeding, chronic vomiting, anemia, and postoperative evaluation of anastomosis. Final diagnosis was diffuse gastric angiodysplasia (n = 1); diffuse jejunal angiodysplasia (n = 1); ulceration in the bulbus (n = 1); celiac disease (n = 1); low differentiated metastatic carcinoma (n = 1); Peutz-Jeghers syndrome (n = 1); adenomatous polyp (n = 1) and stricture formation in anastomosis line (n = 1). During postprocedural follow-up, abdominal pain and elevated amylase levels were noted in three patients and one patient developed abdominal perforation.

CONCLUSION: With the help of technological improvements, we may use enteroscopy as a safe modality more frequently in younger and smaller children.

Double balloon enteroscopy can be safely done in elderly patients with significant co-morbidities

BACKGROUND AND AIM

Performance of double balloon enteroscopy (DBE) on older patients with comorbidities is a matter of safety. We aimed to investigate the utility and safety of DBE in older patients.

METHODS

We retrospectively reviewed the medical records of patients 75 years or older who underwent DBE in our open-access endoscopy unit in a tertiary center. We analyzed the diagnostic yield, therapeutic intervention, and safety including complications of DBE.

RESULTS

Four scheduled DBEs were canceled because of poor conditions. Two hundred and fourteen DBEs were performed in 167 elderly patients. All DBEs were performed under monitored anesthesia care using intravenous propofol administered by anesthesiologists. One half of the patients were male (female : male = 80:87). The mean age of patients was 80.1 ± 3.7 years. Co-morbidity of significant chronic diseases was noted in 208 (97.2%) DBEs. Fifty-one (23.8%) DBEs were performed in patients with American Society of Anesthesiologists (ASA) physical status II, 151 (70.6%) DBEs with ASA class III, and 12 (5.6%) DBEs with ASA class IV. The most common indication was obscure gastrointestinal bleeding. The mean DBE procedure time was 131 ± 51 min. Abnormalities were detected in 129 (60.3%) DBEs with therapeutic interventions performed in 83 (38.8%) cases. Pancreatitis, hypoxia, and aspiration pneumonia developed after three (1.4%), three (1.4%), and two (0.9%) DBEs, respectively, all of which resolved with conservative care.

CONCLUSIONS

Double balloon enteroscopy can be done with acceptable safety in the elderly with high ASA class. DBE shows a high diagnostic yield and can deliver many therapeutic applications.
