Comparison of Cold Biopsy Forceps vs Cold Snare for Diminutive Colorectal Polyp Removal (BIOPANS)

January 27, 2021 updated by: Gabriel RAHMI

Comparison of Cold Biopsy Forceps vs Cold Snare for Diminutive Colorectal Polyp Removal: a Multicenter Randomized Controlled Trial

European guidelines recommend the use of cold snare polypectomy (CSP) for removal of diminutive colorectal polyps (DCP)(5 mm or less). However, for DCP < 4 mm cold biopsy forceps (CBF) may be optional. Moreover, CBF remains the endoscopist's technique of choice for polyp resection and CSP is associated with a failure of specimen retrieval for histology in up to 6.8% of cases. In this study, the investigators aimed to compare the efficacy of CSP with CBF for removal of DCP in routine colonoscopy

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
ACTIVE_COMPARATOR: Cold biopsy forceps (CBF)
Patients will be allocated to the CBF arm after randomization (1:1)
All polypectomy procedures will be standardized amongst the study centers. Endoscopists with a minimal experience of at least 50 CBF and CSP performed the polypectomies CBF : The CBF will be performed using a standard biopsy forceps (Gluton Life ® Life Partners). Multiple biopsies bites were taken until complete resection (as many as needed).
ACTIVE_COMPARATOR: Cold snare polypectomy (CSP)
Patients will be allocated to the CSP arm after randomization (1:1)
All polypectomy procedures will be standardized amongst the study centers. Endoscopists with a minimal experience of at least 50 CBF and CSP performed the polypectomies CSP : The CSB procedure will be performed using a 9 mm cold snare (Exacto ® Life Partners). One to two mm of normal surrounding mucosa will be ensnared around the base of the polyp, followed by mechanical excision without electrocautery

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The primary objective of the study is to compare CBF and CSP in terms of efficacy. The primary end-point is the rate of histological complete resection by anatomopathological examination.
Time Frame: through study completion, an average of 2 years.
Complete histological resection was defined as the absence of visualized residual polyp after saline irrigation as well as negative biopsies of the polypectomy site
through study completion, an average of 2 years.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Specimen retrieval rate (% time of polypectomy)
Time Frame: through study completion, an average of 2 years.
specimen will be immediately suctioned into the operating channel.
through study completion, an average of 2 years.
Procedure time ( overall time between introduction and removal of colonoscope)
Time Frame: through study completion, an average of 2 years.
measure of the time until complete polyp resection is obtained
through study completion, an average of 2 years.
Procedure related adverse events will be collected (adverse events : %, number of event for each groupe) during the procedure or during the follow up period (28 days).
Time Frame: All patients will be followed-up until 28 days post-colonoscopy.
perforation, gastrointestinal and bleeding
All patients will be followed-up until 28 days post-colonoscopy.
