Double balloon enteroscopy: A 7-year experience at a tertiary care Centre

Outcomes of Double Balloon-Enteroscopy in Elderly vs. Adult Patients: A Retrospective 16-Year Single-Centre Study

Background and Aim: Double-balloon enteroscopy (DBE) is a well-established procedure for direct visualisation of the entire small bowel mucosa, and, in contrast with other imaging techniques, allows to perform biopsies and therapeutic interventions. The aim of this study was to evaluate the indications, diagnostic yield, therapeutic yield, and complications of DBE in a cohort of consecutive patients according to patients’ age. Methods: We conducted a retrospective study of consecutive patients who underwent DBE in our endoscopy unit between January 2006 and December 2021. Results: A total of 387 consecutive patients who underwent 460 DBE procedures were included. Mean age of the patients was 63 years. The overall diagnostic yield was 67.6%; vascular lesions were the predominant endoscopic findings (31.5%), followed by polyps or neoplastic masses (17.6%). Older patients (≥65 years) showed statistically higher rates of clinically relevant findings than adult patients (18–65 years) (p = 0.001). Crohn’s disease and polyps or neoplastic masses were more frequent in the younger group (p = 0.009 and p = 0.066, respectively), while vascular lesions and non-specific inflammation were the most common findings in the older group (p < 0.001 and p < 0.001, respectively). The therapeutic intervention rate was 31.7%. Rates of endoscopic treatment were significantly higher in the older group (p < 0.001). Total complications occurred in five procedures (1.1%). Conclusion: In clinical practice, DBE is an efficient diagnostic and therapeutic tool with a high safety profile, particularly in the elderly population.

Single-centre empirical analysis of double-balloon enteroscopy in the diagnosis and treatment of small bowel diseases: A retrospective study of 466 cases

BACKGROUND AND OBJECTIVE

The diagnosis and treatment of small bowel diseases (SBDs) has always been a challenge. The purpose of this study was to evaluate the value of double-balloon enteroscopy (DBE) in the diagnosis and treatment of small bowel diseases.

METHOD

The clinical data of 466 patients who underwent double-balloon enteroscopy (DBE) in the Endoscope Center of Gastroenterology Department of the First People's Hospital of Yunnan Province from Jan. 2015 to Dec. 2020 were analysed retrospectively. The factors included age, sex, indications, endoscopic treatment results, pathological results, discharge diagnosis and so on.

RESULTS

A total of 370 patients underwent 466 double-balloon enteroscopies, among whom 274 underwent one examination and 96 received two-way examinations (oral and transanal approaches). Abnormalities were detected in 299 cases, with a detection rate of 80.81% (299/370). The common indications were occult gastrointestinal bleeding (OGIB) (30.8%, 114/370) and abdominal pain (28.3%, 105/370). The diagnosis rates were 64.9% and 77.1%, respectively. The common positive findings included nonspecific inflammation/erosion (60 cases), ulcers (34 cases), diverticulum (32 cases), polyps (26 cases) and Crohn's disease (CD) (24 cases). The common tumours were lymphoma(12 cases), adenocarcinoma(11 cases) and stromal tumour(8 cases). Lymphoma was mostly located in the ileum, while stromal tumours and adenocarcinoma were mostly located in the duodenum and jejunum. The main endoscopic intervention measures were haemostasis and polypectomy, including haemostatic clip, argon plasma coagulation (APC), endoscopic mucosal resection (EMR), endoscopic trap resection, endoscopic foreign body extraction and other operations, without serious complications.

CONCLUSION

DBE has a high success rate in the diagnosis and treatment of some SBDs, and it is a safe and effective management method.

An update on small bowel endoscopy

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.
