Summary

Colonic obstruction has a high mortality rate, with age, ASA score, renal failure, and proximal colon damage predicting outcomes. Preoperative evaluation aids in risk stratification and treatment decisions for better patient outcomes.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Clinical Epidemiology

Background:

  • Colonic obstruction presents a significant clinical challenge with a high mortality rate.
  • Understanding prognostic factors is crucial for effective patient management and treatment planning.

Purpose of the Study:

  • To evaluate the prognostic significance of various factors on mortality in patients with colonic obstruction.
  • To compare outcomes and prognostic indicators between proximal and distal colonic obstructions.

Main Methods:

  • A cohort of 234 patients undergoing emergency surgery for colonic obstruction was analyzed.
  • Prognostic factors including demographics, comorbidities (ASA score, renal failure), obstruction characteristics (proximal/distal, benign/malignant), and laboratory data were assessed.

  • Univariate and multivariate logistic regression analyses were employed to identify independent predictors of mortality.

    • Main Results:

    • The overall mortality rate was 18.8%, with no significant difference observed between proximal and distal obstructions.
    • Univariate analysis identified age (>70), ASA III-IV score, preoperative renal failure, and proximal colon damage with peritonitis as significant mortality predictors.
    • Multivariate analysis confirmed ASA score, proximal colon damage, and preoperative renal failure as independent predictors of mortality.

    Conclusions:

    • Colonic obstruction remains associated with substantial mortality.
    • Preoperative assessment of prognostic factors is vital for stratifying patients by mortality risk and guiding therapeutic decisions.
    • Similar principles of risk stratification should be applied to both proximal and distal colonic obstructions.
