Overview

Observational analysis compares surgical outcomes in PDM versus Non-PDM patients, suggesting increased complexity with PDM.

Key Points

  • This research aims to compare surgical outcomes between patients with Persistent Descending Mesocolon (PDM) and those without it.
  • Conducted a systematic search of electronic databases for relevant studies.
  • Applied random-effects model for high statistical heterogeneity and fixed-effects model for low heterogeneity.
  • Analyzed data using Stata software version 18.0.
  • Included six observational studies with 2437 total patients.
  • PDM group had a significantly longer operative time (MD: 28.43 minutes, p = 0.03).
  • No significant difference in intraoperative blood loss between groups.
  • Postoperative hospital stay was similar for both groups.
  • Overall complication rates showed no significant differences (OR=1.14, p = 0.69).
