RISS Versus ESP Block in Laparoscopic Cholecystectomy
Turkey (Türkiye)80 participantsStarted 2026-06-18
Plain-language summary
This prospective randomized controlled trial aims to compare the analgesic efficacy and effects on diaphragmatic function of bilateral erector spinae plane (ESP) block and bilateral rhomboid intercostal-subserratus plane (RISS) block in patients undergoing elective laparoscopic cholecystectomy. Postoperative pain scores, opioid consumption, diaphragmatic excursion, pulmonary function, and recovery outcomes will be evaluated.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1This trial compares two nerve block techniques for pain control after laparoscopic gallbladder removal — can you explain what the RISS block and the ESP block are, and how they differ from what you'd normally use for my surgery?
2The trial is measuring how much tramadol patients need after surgery — does that mean there's still a chance I'd need significant pain medication either way, and how would that fit with my overall pain management plan?
3Since this trial hasn't started recruiting yet, what's your sense of the timeline, and would I have access to whichever block technique is proven better even if I'm not in the study?
4Both of these appear to be regional anesthesia approaches — are there any risks specific to either block technique that I should weigh against the potential benefit of better postoperative pain control?
5Would it make sense for me to discuss with the anesthesia team which of these two approaches, or perhaps a different pain strategy altogether, might be most appropriate for my specific situation before committing to anything?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
