Pancreatic surgery and length of hospital stay: meta-analysis of randomized clinical trials.
Synthesis in BJS open, 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
backgroundLength of hospital stay (LOS) is a commonly reported postoperative outcome measure in pancreatic surgery. However, LOS may be influenced by various factors, including healthcare systems, cultural traditions, and readmission rate. This systematic review and meta-analysis investigated LOS in pancreatic surgery.
methodsA meta-analysis was conducted to identify all randomized clinical trials (RCTs) of pancreatic surgery reporting LOS. Analyses were conducted using a random-effects model with mean differences as the effect estimator for the continuous outcome LOS.
resultsIn all, 186 RCTs published between 1994 and 2025, comprising 28 381 patients, were included. The mean LOS differed significantly by type of resection (P = 0.003) and by country (P < 0.001). Country remained a statistically significant factor after adjusting for readmission rate, year of study, and type of resection. The shortest LOS was observed in the USA, with a pooled value of 11 days (95% confidence interval (c.i.) 9.93 to 12.32) and the longest was seen in Japan, with a pooled value of 28 days (95% c.i. 25.60 to 31.67). Subgroup analysis of studies comparing minimally invasive and open surgery showed a mean LOS difference of 2 days (95% c.i. -2.79 to -0.85; prediction interval -7.70 to 4.06). However, this effect varied across countries, with mean LOS differences ranging from 1 to 6 days.
conclusionLOS after pancreatic surgery exhibited substantial statistical heterogeneity based on country, the type of operation, and access. This highlights the importance of considering contextual factors when evaluating and comparing LOS as an outcome measure in pancreatic surgery.
