Risk Factors for Severe Postoperative Complications After Laparoscopic Colorectal Cancer Surgery in Octogenarians: A Retrospective Cohort Study

YLYuegang LiJDJinbo DuWQWenlong Qiu

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.

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.

Study Design

Type

Cohort (n=170)

Multicenter

No

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

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

Main Result

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

p-value: p=<0.01

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

Abstract

Purpose: To evaluate the incidence and risk factors of severe postoperative complications in patients aged ≥ 80 years undergoing laparoscopic colorectal cancer surgery. Patients and Methods: Patients aged ≥ 80 years who underwent laparoscopic colorectal cancer surgery between February 2007 and September 2018. Severe complications were defined as Clavien–Dindo grade III or higher. Univariate and multivariate logistic regression analyses were performed to identify risk factors. Results: Among 170 patients, 26 (15.3%) experienced severe postoperative complications. Gastrointestinal events were most common (8.0%), followed by respiratory (3.5%) and cardiovascular (2.9%) complications. Two patients (1.2%) died postoperatively. Multivariate analysis identified estimated blood loss > 100 mL (OR = 4.53, 95% CI: 1.75– 11.70, P 100 mL were independent risk factors. Preoperative anemia and ASA III were borderline predictors. These factors may aid in perioperative risk stratification and surgical decision-making in elderly patients.

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.
