However, LOS may be influenced by various factors, including healthcare systems, cultural traditions, and readmission rate.

The mean LOS differed significantly by type of resection (P = 0.003) and by country (P &amp;lt; 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. \u22122.79 to \u22120.85; prediction interval \u22127.70 to 4.06). However, this effect varied across countries, with mean LOS differences ranging from 1 to 6 days.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>LOS after pancreatic surgery exhibited substantial statistical heterogeneity based on country, the type of operation, and access.
