3°C Saline Injection at the Duodenal Papilla to Prevent Post-ERCP Pancreatitis

A Phase 2/3 interventional study of Topical Cold Sterile Saline Irrigation of the Duodenal Papilla (3°C) and Standard ERCP (Usual Care) in Pancreatitis, sponsored by Universidad Nacional de Colombia. Completed at 1 site in Colombia. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-02-02.

Study summary

Endoscopic retrograde cholangiopancreatography (ERCP) is an endoscopic procedure used to diagnose and treat problems in the bile ducts and pancreas. One of its most common complications is **post-ERCP pancreatitis**. This multicenter randomized clinical trial will evaluate whether **cooling the duodenal papilla** with **sterile saline at 3°C** immediately after ERCP can reduce the risk of post-ERCP pancreatitis compared with standard ERCP care.

Adults **≥18 years** with a **native papilla** scheduled for diagnostic or therapeutic ERCP at **three high-complexity university hospitals in Bogotá/Cundinamarca (Colombia)** will be randomized **1:1** to: (1) **intervention**-instillation of **250 mL** of **3°C sterile saline** in **five 50-mL aliquots** directed to the papilla through the endoscope working channel at the end of ERCP, with aspiration between aliquots; or (2) **control**-standard ERCP with no additional instillation. The saline temperature will be verified immediately before administration. Standard preventive measures (e.g., rectal NSAIDs, lactated Ringer's hydration, prophylactic pancreatic stent when clinically indicated) may be used per usual care and will be recorded.

The **primary outcome** is post-ERCP pancreatitis at **24 hours**, defined using Cotton criteria (new/worsening abdominal pain plus serum amylase or lipase ≥3× the upper limit of normal). Secondary outcomes include pancreatitis severity, other ERCP-related complications, and safety through day 7 (including a telephone follow-up). Participants will be screened and consented before sedation; randomization occurs at the end of the ERCP; clinical assessment and labs are performed at 24 hours; follow-up continues through day 7.

Safety monitoring will include systematic assessment for potential effects related to local cooling (e.g., chills, duodenal spasm, mucosal bleeding at the instillation site, or clinically relevant hypothermia) at 2 and 24 hours, with surveillance for serious adverse events through day 7.

Study arms

  • Experimental
    Cold Saline Papillary Irrigation (3°C)

    At the end of ERCP, 250 mL of sterile saline at 3°C is instilled onto the duodenal papilla in five 50-mL aliquots through the endoscope working channel, with aspiration between aliquots to enhance the local effect.

    Procedure: Topical Cold Sterile Saline Irrigation of the Duodenal Papilla (3°C)

  • Active comparator
    Standard ERCP (Usual Care)

    Standard ERCP performed with no additional saline instillation. Usual prophylaxis may be used when clinically indicated (e.g., rectal NSAIDs, lactated Ringer's hydration, prophylactic pancreatic stent in high-risk cases) and is recorded.

    Other: Standard ERCP (Usual Care)

Interventions

  • ProcedureTopical Cold Sterile Saline Irrigation of the Duodenal Papilla (3°C)

    250 mL of 3°C sterile saline administered in five 50-mL aliquots directed to the papilla via the endoscope working channel at ERCP completion, with aspiration between aliquots; saline temperature is verified immediately before administration

  • OtherStandard ERCP (Usual Care)

    Standard ERCP performed with no additional saline instillation. Usual prophylaxis may be used when clinically indicated (e.g., rectal NSAIDs, lactated Ringer's hydration, prophylactic pancreatic stent in high-risk cases) and is recorded.
