Summary

This study aims to compare indomethacin and the combination of indomethacin and aggressive lactated Ringer infusion in terms of efficacy in preventing post-ERCP acute pancreatitis (PEP).

Detailed description

This study aims to compare indomethacin and the combination of indomethacin and aggressive lactated Ringer infusion in terms of their efficacy in preventing PEP regardless of baseline risk in all eligible patients who have consecutively undergone ERCP. The intention is to confirm initial literature finding with a large sample size and a prospective, randomised, multicentre design to study and compare the efficacy of the two different prophylaxis strategies. The interest is determined by the need to assess whether there is a superiority of combination prophylaxis with indomethacin and a strong infusion of lactated Ringer against the exclusive administration of endorectal indomethacin, with a consequent considerable impact on the management of PEP. Shouldn't forget that both indomethacin and lactated Ringer have in the various studies only reduced the incidence of PEP compared to placebo. Therefore, PEP remains a possible complication even after prophylaxis with a single measure, even in low-risk patients. If the study demonstrates the superiority of combination prophylaxis, it could offer this to all patients with gains in PEP, hospitalisation, and complication management costs. It should be noted that, compared with previous studies, this protocol doesn't include a placebo control arm. This choice, shared by all the centres involved, is dictated by the awareness that literature studies have already documented the superiority of both indomethacin and Ringer's lactate in PEP prophylaxis compared to placebo. Moreover, although some studies raise doubts about the prophylactic efficacy of indomethacin in low-risk patients, it was decided not to include a placebo arm because of ethical misgivings about not proposing a treatment with a low risk of side events, as recommended moreover by international guidelines. Finally, the study aims to assess the occurrence of any adverse events in the two groups studied.

Conditions

• Pancreatitis, Acute

Interventions

Type	Name	Description
DRUG	Indomethacin suppository	Control Group: Patients will be randomized to receive a 100 mg indomethacin suppository will be administered immediately before the endoscopic procedure (20-30 minutes) and saline infusion will be given as needed.
COMBINATION_PRODUCT	Indomethacin suppository and high-flow lactated ringer infusion combination	Interventional group: Patients will be randomized to receive an indomethacin suppository that will be administered immediately before (20-30 minutes) the endoscopic procedure in combination with a lactated Ringer's infusion that will be administered with the following weight-based schedule: 3 cc/kg/h during ERCP, a bolus of 20 cc/kg after ERCP, and again 3 cc/kg/h for 8 hours after ERCP.
