ERCP management of cystic duct stones with a rare anatomic variant in octogenarian: a case report.
Article in Frontiers in surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Endoscopic retrograde cholangiopancreatography (ERCP) is a critical therapeutic modality for bile duct stones; however, cases of cystic duct stones (CDS) managed by ERCP alone are rarely reported. Herein, we present a rare case of an octogenarian patient with an anatomic variation consisting of low and left-sided insertion of the cystic duct (CD) in whom both bile duct stones and CDS were successfully treated using ERCP. Case presentation: An 82-year-old male presented to our hospital with an acute epigastric pain associated with fever and chills. Diagnostic imaging revealed multiple bile duct stones and CDS, along with an anatomical variant of the low and left-sided insertion of the CD. The patient declined to undergo laparoscopic cholecystectomy (LC) with laparoscopic common bile duct exploration (LCBDE) because of concerns about surgical risks. All stones were successfully removed via ERCP, with preservation of the gallbladder function. The patient experienced no postoperative complications, and no stone recurrence was detected during the 1-year follow-up period. Conclusion: This case demonstrates that an ERCP-only approach represents a safe and effective therapeutic strategy for patients with biliary anatomic variations complicated by complex stone disease, particularly in the oldest-old (≥80 years) patients who are ineligible for laparoscopic surgery. The postoperative recurrence rate of biliary stones remained high in this patient population. In such cases, a repeat ERCP is a viable and reasonable therapeutic option.
