Why the study?

The study was conducted to evaluate the incidence and risk factors of severe postoperative complications in patients aged ≥ 80 years undergoing laparoscopic colorectal cancer surgery.

Population

170 patients aged ≥ 80 years undergoing laparoscopic colorectal cancer surgery

Comparison

Patients with vs without severe postoperative complications

Design

Retrospective cohort study

Key result

Age ≥85 years (OR 4.48) and intraoperative blood loss >100 mL (OR 4.53) independently predicted severe postoperative complications in octogenarians undergoing laparoscopic colorectal cancer surgery.

Overview

Supports vigilance for severe complications in patients ≥85 or with blood loss >100mL but should not change practice; leaves open modifiable risks pending prospective trials.

Key Points

  • The aim is to assess the incidence and identify risk factors for severe postoperative complications in octogenarians undergoing laparoscopic colorectal cancer surgery.
  • Retrospective cohort study of patients aged ≥ 80 years undergoing laparoscopic colorectal cancer surgery from February 2007 to September 2018.
  • Analysis of severe complications defined as Clavien–Dindo grade III or higher using univariate and multivariate logistic regression.
  • Severe postoperative complications occurred in 15.3% of 170 patients.
  • Independent risk factors include estimated blood loss > 100 mL (OR = 4.53, 95% CI: 1.75–11.70, P < 0.01) and age ≥ 85 years (OR = 4.48, 95% CI: 1.27–15.79, P = 0.02).
  • Preoperative anemia (hemoglobin < 120 g/L) and ASA III showed borderline significance as risk factors.

Structured PICO

P
Population
170 patients aged ≥80 years (median age 82, 59.4% male) undergoing elective laparoscopic radical resection for pathologically confirmed colorectal adenocarcinoma at a single center in China.
I
Intervention
Elective laparoscopic curative-intent resection for colorectal cancer
O
Outcome
Occurrence of severe postoperative complications, defined as Clavien–Dindo grade III or higher events within 30 days after surgerysafety

Main Result

Effect estimate: OR 4.53 (95% CI 1.75-11.70)

p-value: p=<0.01

In octogenarians undergoing laparoscopic colorectal cancer surgery, age ≥85 years and intraoperative blood loss >100 mL independently predict severe 30-day postoperative complications.

Limitations

  • Retrospective, single-center design may limit generalizability
  • Sample size may be insufficient to detect modest associations
  • Frailty indices and comprehensive geriatric assessments were not included
  • Right-sided, left-sided, and rectal resections were analyzed collectively
  • Retrospective, single-center design
  • Very small number of diverting stomas precluded meaningful statistical evaluation

Cite This Study

Li et al. (2026) conducted a cohort in Colorectal cancer (n=170). Laparoscopic colorectal cancer surgery was evaluated on Severe postoperative complications (Clavien-Dindo grade ≥III) (OR 4.53, 95% CI 1.75-11.70, p=<0.01). Age ≥85 years (OR 4.48) and intraoperative blood loss >100 mL (OR 4.53) independently predicted severe postoperative complications in octogenarians undergoing laparoscopic colorectal cancer surgery.
