Brief summary
The purpose of this study is to determine whether the use of antibiotic prophylaxis is appropriate when performing a pancreatic cyst fine needle aspiration guided by endoscopic ultrasonography.
Detailed description
The incidence of infection after a pancreatic cyst fine needle aspiration guided by endoscopic ultrasonography (EUS-FNA) is not well known. Antibiotic prophylaxis is recommended in clinical guidelines despite the lack of evidence of its usefulness. Our hypothesis is that the risk of infection will not be higher with placebo, and risks associated to the use of antibiotics might even increase with the use of prophylaxis. The main objective of the project is to assess the risk of infection after the procedure and to determine whether the use of antibiotic prophylaxis is appropriate. The study is a phase IV, multicenter, double-blinded, randomized, placebo-controlled, and non-inferiority trial . We have designed a study with two parallel treatment groups. Patients will be randomized to the prophylaxis or to the placebo group. All patients will be followed for 21 days or until resolution of complications. To evaluate this primary objective with a non inferiority study, we have estimated that a total of 218 patients will be needed (109 per group) . The main secondary objective is to assess the incidence of complications related to the use of antibiotic prophylaxis (i.e. allergic reactions, secondary infections or drug-resistant infections).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Risk of infection of a pancreatic cyst or infection related to the procedure | 21 days | The infection can be defined as confirmed if there is a positive culture of the lesion content or if there is suspicion by clinical and image techniques (CT, MRI), and a positive blood culture is obtained. It will be defined as suspected when clinical and/or image is suggestive of cyst infection, but microbial confirmation is not obtained. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Risk of fever | 21 days | This will be measured prior to discharge. In case of clinical suspicion of bacteraemia at any moment during the follow up, blood cultures will be obtained. |
| secondary effects, allergic reactions, and drug resistant or secondary infections | 21 days | — |
