  "abstract": "Background: Percutaneous transhepatic gallbladder drainage (PTGBD) is a standard drainage option for patients with acute cholecystitis at high surgical risk. The association of between catheter diameter and clinical outcomes remains unclear. We compared short-term clinical outcomes between 6-Fr and 8-Fr catheters used for PTGBD.\n\nMethods: This single-center retrospective observational study included patients who underwent PTGBD for acute calculous cholecystitis. Baseline characteristics between the 6-Fr and 8-Fr groups were adjusted using propensity score matching (PSM). Outcomes were assessed for adverse events (AEs), technical success, clinical success, and 30-day mortality.\n\nResults: A total of 127 and 149 patients were included in the 6-Fr and 8-Fr groups, respectively. After PSM, 71 matched pairs were analyzed. After matching, the AE rate was significantly higher in the 6-Fr group than in the 8-Fr group (28.2% vs. 9.9%; risk difference [RD] 0.18; relative risk 2.85; p = 0.009). Clinical success was significantly higher in the 8-Fr group at days 5 and 7 (91.5% vs. 100%; RD = − 0.08; p = 0.041) but was similar between the groups by day 14 (98.6% vs. 100%; p > 0.999). No significant between-group differences were observed in technical success or 30-day mortality.\n\nConclusions: Compared with 6-Fr catheters, 8-Fr catheters were associated with fewer short-term AEs and may be associated with earlier clinical improvement. An 8-Fr catheter may be a reasonable option for short-term PTGBD management.\n\nSupplementary Information: The online version contains supplementary material available at https://doi.org/10.1186/s12876-026-05210-9.",
