Brief 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.
Interventions
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_PRODUCTIndomethacin 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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of PEP | Assessed 24 hours after procedure | Onset of acute post-ERCP pancreatitis (PEP) at 24 hours after the procedure according to Cotton's criteria \[Mild, Moderate, Severe\] |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Severity of PEP | Assessed 72 hours after the onset of acute pancreatitis | The effect on the severity of pancreatitis occurring in patients treated with indomethacin or indomethacin and lactated Ringer's will be evaluated and compared according to Atlanta's criteria \[Mild, Moderate, Severe\] (72 hours after the onset of acute pancreatitis). |
| Increased amylase and lipase | Assessed 24 hours from baseline | The effect on the occurrence of increased amylase and lipase values in patients treated with indomethacin or indomethacin and Ringer's lactate will be evaluated and compared. The difference in plasma amylase and lipase levels post-ERCP will be assessed at 24 hours from baseline. |
| Onset of any adverse events | Assessed postoperative bleeding within 30 days of surgery; increased plasma creatinine at 24 hours post-procedure; pulmonary oedema at 2, 8 and 24 hours after the procedure; water overload at 2, 8 and 24 hours after the procedure; | The onset of any adverse event will be evaluated and compared, specifically: * intra-operative bleeding; * Postoperative bleeding (within 30 days of the procedure); * increased plasma creatinine compared to baseline (at 24 hours post-procedure); * pulmonary edema (2, 8 and 24 hours after the procedure) * fluid overload (2, 8 and 24 hours after the procedure); * other (events that happened during the hospital stay and related to the procedure or study). |
| Duration of Hospitalisation | Assessed average length of stay up to 30 days | The average duration of hospitalization in the two arms will be evaluated up to 30 days after randomization. |
