according to a retrospective multicenter study.
These findings suggest that endoscopists should prioritize dual stent placement when feasible, and consider adding a second stent in patients who previously received a single stent, James D. Haddad, MD, of the University of Texas Southwestern, Dallas, and colleagues reported.
The American Gastroenterological Association (AGA) has recognized the role of endoscopic drainage in managing acute cholecystitis in high-risk patients, but specific guidance on optimal technique and follow-up remains unclear, the investigators wrote in Techniques and Innovations in Gastrointestinal Endoscopy.
“Despite accumulating data and increased interest in this technique, clear guidance on the ideal strategy for ETGBD is lacking,” Dr. Haddad and colleagues wrote. “For example, the optimal size, number, and follow-up of cystic duct stents for patients undergoing ETGBD has not been well established.”
To address this knowledge gap, the investigators analyzed data from 75 patients at five academic medical centers who had undergone ETGBD between June 2013 and October 2022. Patients were divided into two groups based on whether they received one or two cystic duct stents.
The primary outcome was clinical success, defined as symptom resolution without requiring another drainage procedure. Secondary outcomes included technical success (defined as successful stent placement), along with rates of adverse events and unplanned reinterventions.
Out of the 75 patients, 59 received a single stent, while 16 received dual stents. The median follow-up time was 407 days overall, with a longer follow-up in the single-stent group (433 days), compared with the double-stent group (118 days).
Clinical success was reported in 81.3% of cases, which technical success was achieved in 88.2% of cases.
Patients who received two stents had significantly lower rates of unplanned reintervention, compared with those who received a single stent (0% vs 25.4%; P = .02). The median time to unplanned reintervention in the single-stent group was 210 days.
Use of a 7 French stent was strongly associated with placement of two stents (odd ratio [OR], 15.5; P = .01). Similarly, patients with a prior percutaneous cholecystostomy tube were significantly more likely to have two stents placed (OR, 10.8; P = .001).
Adverse event rates were uncommon and not statistically different between groups, with an overall rate of 6.7%. Post-endoscopic retrograde cholangiopancreatography pancreatitis was the most common adverse event, occurring in two patients in the single-stent group and one patient in the double-stent group. There were no reported cases of cystic duct or gallbladder perforation.
“In conclusion,” the investigators wrote, “ETGBD with dual transpapillary gallbladder stenting is associated with a lower rate of unplanned reinterventions, compared with that with single stenting, and has a low rate of adverse events. Endoscopists performing ETGBD should consider planned exchange of solitary transpapillary gallbladder stents or interval ERCP for reattempted placement of a second stent if placement of two stents is not possible at the index ERCP.”
The investigators disclosed relationships with Boston Scientific, Motus GI, and ConMed.
