Does rectal ketoprofen prevent post ERCP pancreatitis?

Endoscopic retrograde cholangiopancreatography (ERCP) is a commonly used procedure in the management of pancreatic and biliary diseases. Acute pancreatitis is the most common complication following ERCP. Among many medications, nonsteroidal anti-inflammatory drugs (NSAIDs) were subject of numerous trials concerning post ERCP pancreatitis (PEP) prophylaxis. By inhibiting phospholipase A2, these drugs could intervene in the pathogenesis of the disease therefore limiting its occurrence. The use of some rectal NSAIDs agents was shown, to be advantageous in preventing this complication but there were not enough data on ketoprofen. The aim of this study was to assess the efficacy of rectal ketoprofen prophylactic administration in reducing the risk of PEP.

The study was a non randomized retrospective single center study conducted between 2014 and 2018 on 242 patients divided into control and trial group receiving 100 mg of rectal Ketoprofen 30 mins before ERCP. PEP was defined as a new or exacerbated abdominal pain, in association with an elevation of serum lipase at least three times higher than the normal upper limit within and lasting more than 24 h after the procedure requiring a re-admission or a prolongation of the hospital stay. This endpoint was determined by comparing the number of patients presenting PEP in the NSAIDs group vs. the control group using Fisher exact test, with p < 0.05 representing a significant statistical value.

Pancreatitis developed in 6% after ERCP, 5 of them being in the trial group and 9 in the control group. Additionally, statistical calculations showed a non significant difference between the two groups in the prevalence of PEP.

Rectal ketoprofen administration before ERCP does not have any effect in preventing pancreatitis post ERCP.
