Efficacy And Safety of the Power Spiral Enteroscopy: A Prospective Study

Aims The aim of our study is to evaluate efficacy and safety of this novel method in patients with suspected small bowel disease in our institution.

Methods This prospective study with descriptive evaluation is conducted at Institut Arnault Tzanck, France

Inclusion criteria Patients with suspected small bowel disease with a positive finding on prior small bowel capsule endoscopy for deep antegrade or retrograde enteroscopy are enrolled after obtaining informed consent.

Exclusion criteria Patients under the age of 18, bariatric surgery, suspected or history of bowel obstruction, stenosis or suspected oesophageal stricture, cirrhosis with gastric or oesophageal varices, contraindication to sedation or general anaesthesia for any reason are excluded from the study.

Primary endpoint The diagnostic yield or reaching target of PSE (Power Spiral Enteroscopy)in patients with one or more positive findings on prior small bowel capsule endoscopy.

Secondary endpoints Percentage of cases with total antegrade enteroscopy (progression up to ileum à caecum), Rate of therapeutic interventions, Adverse events during the procedure. Duration of the procedure.

Results Fifty (50) patients met the inclusion criteria.

The diagnostic yield in our study was 62 % (31/50).

Diagnoses included AVM (48 % (24/50)), polyps/neoplastic lesions (4 % (2/50)), inflammatory lesions (eg, ulcers, erosions) (10 % (5/50)) and 10 % (5/50) of the patients had other findings: jejunal diverticula (n = 3), jejunal lipoma (n = 1) and phlebectasia (n = 1). Tissue sampling was performed in 3/50 patients (6 %).

Interventional PSE was observed in 56 % of patients (28/50)

Median total procedure time was 25 min (range 7–38 min).

Procedure-related AEs were observed in 14 patients (28 %) such as superficial mucosal tears (four patients in the small bowel, ten in the oesophagus), all of whom were clinically asymptomatic.

No serious procedure-related events were noted.

Conclusions Motorized spiral enteroscopy in an alternative technique for diagnostic and therapeutic small bowel enteroscopy.
