Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 18 and older who are scheduled for distal pancreatectomy.

Probably not a fit

Patients with certain pre-existing conditions, such as myasthenia gravis or those undergoing specific types of pancreatic surgeries, may not benefit from this study.

What this trial studies

This clinical trial investigates the use of intrapapillary botulinum toxin injections as a preventive measure against postoperative pancreatic fistula (POPF) in patients undergoing distal pancreatectomy. The study aims to assess the efficacy of this intervention in reducing the incidence and severity of POPF, a common and serious complication following pancreatic surgery. Eligible participants include adults scheduled for distal pancreatectomy, while those with certain medical conditions or prior surgeries are excluded. The trial is conducted at Assistance Publique - Hôpitaux de Paris.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the occurrence of postoperative pancreatic fistulas, improving recovery and outcomes for patients undergoing pancreatic surgery.

How similar studies have gone: While various prophylactic strategies for POPF have been attempted, the use of botulinum toxin injections is a novel approach that has not been extensively tested in this context.
