The results emerged from the small, single-center SOCCER trial of 152 patients recruited from March 2022 to October 2024 and are published in The American Journal of Gastroenterology.
Both groups had a slightly higher number of female participants, and the mean ages of the participants were 61.9 years in the forceps group and 68.3 years in the no forceps group.
First author Steven M. Hadley Jr, an MD candidate at Northwestern Feinberg School of Medicine in Chicago, and colleagues reported that forceps assistance in difficult cannulations yielded significantly higher success rates than no forceps assistance (100% vs 83.9%; P < .001).
The investigators noted that difficult cannulations during ERCP have a frequency of 42%. Cannulation failure is associated with increased morbidity — including longer hospitalization, increased ICU admissions, readmissions, and increased financial cost — as well as mortality rates of up to 10%.
SOCCER defined difficult cannulation as a papilla in or on the rim of a diverticulum, five or more attempts, attempts lasting 5 or more minutes, or two or more unintended pancreatic duct wire passages. Other features were redundant tissue overlaying the papilla or a type 2, 3, or 4 papilla.
The study found forceps assistance also had a nonstatistically significant lower rate of difficult cannulations than no forceps (57.1% vs 69.1%; P = .132). The rate of post-ERCP pancreatitis (PEP) was similarly low in both groups: 5.7% with forceps vs 3.7% without forceps (P = .705). The no forceps group had significantly more cannulation attempts after randomization than the forceps group (14 vs 8.3; P = .026).
Patients who crossed over to forceps assistance all had successful cannulations.
The technique has long been used to overcome cannulation difficulties, said Timothy B. Gardner, MD, MS, a gastroenterologist at the Dartmouth Hitchcock Medical Center in Lebanon, New Hampshire, and a coauthor of the study. “It was particularly effective for cannulations with redundant tissue limiting access to the papilla,” Gardner told GI & Hepatology News. “We decided to design a randomized trial to determine the extent to which this technique worked. We believed our study would answer an important question that would hopefully lead to an improvement in endoscopy practice.”
While a few case reports and video demos had described the technique, no trials had assessed its effectiveness, Hadley added. “We found the technique to be effective based on our experience, but it was exciting to see that a rigorously designed randomized trial proved that it is indeed a very effective technique to facilitate cannulation.”
Hadley noted the technique does not increase PEP incidence, unlike the commonly used precut sphincterotomy and the double-wire method for difficult cannulations. “As a result, the forceps-assisted technique may be an effective first-line option and may reduce the need for additional, more invasive procedures including surgery and repeat ERCP to obtain the therapeutic intent of the original ERCP.”
The paper outlines the technique’s methodology, he added, “so we believe endoscopists who read the manuscript will be able to start implementing the technique into their practice.”
Commenting on the paper but not involved in it, Christopher J. DiMaio, MD, regional director of Endoscopy for Northwell Health Physician Partners Gastroenterology and a gastroenterologist in Greenlawn, New York, called it potentially helpful but aimed at a niche group of expert practitioners. “The technique appears safe and very effective, which is the number one concern, and I would definitely keep it in my back pocket,” he said. “I expect it will be used more commonly now because of this study.”
He added that although expert endoscopists are familiar with the approach, they use more time-tested and sometimes more aggressive maneuvers to cope with difficult cannulations. “But this is a simple technique using a device that should be available to most high-volume endoscopists.”
DiMaio also noted that he would have liked to see an actual decrease in PEP incidence in the intervention group.
Looking ahead, Hadley said it would be interesting to compare the effectiveness of the double-wire technique against forceps-assisted cannulation in a randomized context. “A study we’re already looking into is seeing whether physician experience with the technique impacts outcomes.”
This study was supported by the American College of Gastroenterology. The authors and DiMaio reported having no relevant competing interests.
