Claim 1 of 7SupportedFor patients undergoing elective intestinal resection for Crohn disease, cumulative surgical recurrence rates are lower with laparoscopic versus open surgery, according to a study published online July 23 in Techniques in Coloproctology.View evidenceHide evidence

Why this verdict

The abstract-level profile supports an association between surgical approach and recurrence: Kaplan–Meier analysis showed lower cumulative surgical recurrence after laparoscopic compared with open surgery. The headline is prominent but frames the finding as study-based and does not make an explicit causal claim.

1

Study evidence

Open surgery (vs laparoscopic) was associated with a higher hazard of long-term surgical recurrence after elective intestinal resection for Crohn’s disease in multivariable analysis.HR 1.76 (95% CI 1.14–2.69) for open versus laparoscopic surgery

“A retrospective single-centre study of patients undergoing elective intestinal resection for CD between 1995 and 2020 was conducted.”
Claim 2 of 7SupportedLukas Schlager, M.D., from the Medical University of Vienna and colleagues conducted a retrospective study involving patients undergoing elective intestinal resection for Crohn disease between 1995 and 2020 to examine risk factors for surgical recurrence; data were included for 641 patients followed for a mean of 12.4 years.View evidenceHide evidence

As stated641 patients; mean follow-up 12.4 years

Why this verdict

The profile reports a retrospective study of elective intestinal resection for Crohn's disease from 1995 to 2020, examining risk factors for surgical recurrence, with 641 patients and mean follow-up of 12.4 years. The story omits that the study was single-centre, but the stated claim itself is supported.

As statedhazard ratio 1.76

Why this verdict

The profile reports that open surgery was associated with higher hazard of surgical recurrence in multivariable Cox regression, HR 1.76 with 95% CI 1.14–2.69. It also reports smoking, female sex, and microscopically inflamed resection margins as associated predictors, although abstract-level evidence does not provide their individual HRs.

As stated7.0% overall

Why this verdict

The profile reports severe perioperative complications occurred in 7.0% overall and did not influence recurrence, with p = 0.574. The story's associational wording is consistent with the evidence.

Study evidence

Severe perioperative complications occurred in 7.0% of patients (3.3% laparoscopic, 9.7% open) and were reported not to influence long-term surgical recurrence (p = 0.574).p = 0.574

“Severe perioperative complications (7.0% overall; 3.3% laparoscopic versus 9.7% open) did not influence recurrence (p = 0.574).”
Claim 7 of 7SupportedThe authors said causal inference is limited by the observational design, but that the consistency of Kaplan–Meier and Cox regression findings over 25 years suggests the surgical approach may be a modifiable factor influencing long-term outcomes.View evidenceHide evidence

Why this verdict

The paper profile includes the observational-design caveat limiting causal inference and the authors' interpretation that surgical approach may be a modifiable factor influencing long-term outcomes. The claim is hedged as 'may' and is therefore consistent with the abstract-level profile.

What the story left out

Important study details the story did not include.

  • Single-centre nature of the cohort, affecting generalisability.

    The paper profile identifies the study as a retrospective single-centre cohort and lists limited generalisability as a limitation. The story does not mention the single-centre setting.

  • Long inclusion period from 1995 to 2020 may introduce heterogeneity from changes in surgical technique, perioperative care, medical management, or patient selection.

    The story reports the 1995–2020 period but does not mention the limitation that practice changes over that long period could affect applicability or confound interpretation.

6 things the story did carry across
  • Main study design and population: retrospective cohort of Crohn's disease patients undergoing elective intestinal resection from 1995 to 2020, N = 641, mean follow-up 12.4 years.
  • Primary finding: laparoscopic surgery was associated with lower cumulative surgical recurrence than open surgery in Kaplan–Meier analysis.
  • Adjusted primary finding: open surgery versus laparoscopic surgery was associated with higher recurrence hazard in multivariable Cox regression, HR 1.76.
  • Secondary risk factors: smoking, female sex, and microscopically inflamed resection margins were associated with higher recurrence hazard, but abstract-level evidence does not provide their adjusted effect estimates.
  • Severe perioperative complications: occurred in 7.0% overall and were not associated with long-term recurrence; rates differed by approach in the abstract-level profile.
  • Causal inference limitation from retrospective observational design.

1Lead resulthuman in vivoAssess whether surgical approach (laparoscopic vs open) is associated with long-term surgical recurrence/reoperation after elective intestinal resection for Crohn’s disease, and estimate its independent effect adjusting for confounders.Retrospective single-centre cohort (elective intestinal resection for Crohn’s disease, 1995–2020)Expand

In plain English

Retrospective single-centre cohort (1995–2020) of 641 elective intestinal resections for Crohn’s disease comparing laparoscopic (n=270) versus open (n=371) approach for long-term surgical recurrence. Kaplan–Meier analysis showed lower cumulative recurrence after laparoscopy (log-rank p = 0.010). In multivariable Cox regression, open surgery was associated with higher hazard of surgical recurrence (HR 1.76, 95% CI 1.14–2.69). Mean follow-up was 12.4 years.

Key findings

  • Open surgery (vs laparoscopic) was associated with a higher hazard of long-term surgical recurrence after elective intestinal resection for Crohn’s disease in multivariable analysis.HR 1.76 (95% CI 1.14–2.69) for open versus laparoscopic surgery
  • Severe perioperative complications did not influence long-term surgical recurrence.
“A retrospective single-centre study of patients undergoing elective intestinal resection for CD between 1995 and 2020 was conducted.”
What this piece can’t prove
  • Retrospective single-centre cohort study, limiting causal inference and generalisability.
  • Potential residual confounding and selection bias; abstract does not list covariates adjusted for in the multivariable model.
  • Long inclusion period (1995–2020) may introduce heterogeneity due to changes in surgical technique and perioperative care over time.
2human in vivoIdentify additional risk factors for long-term surgical recurrence (e.g., smoking, sex, microscopically inflamed resection margins) in the same cohort.Retrospective cohort; multivariable Cox regressionExpand

In plain English

In a retrospective single-centre cohort of 641 patients undergoing elective intestinal resection for Crohn's disease (1995–2020; mean follow-up 12.4 years), multivariable Cox proportional hazards regression identified smoking, female sex, and microscopically inflamed resection margins as independent predictors associated with a higher hazard of long-term surgical recurrence. The abstract does not provide adjusted effect estimates for these specific predictors.

Key findings

  • Smoking was associated with a higher hazard of long-term surgical recurrence in multivariable Cox regression.
  • Female sex was associated with a higher hazard of long-term surgical recurrence in multivariable Cox regression.
“Demographics, disease features, surgical details and complications were analysed.”
What this piece can’t prove
  • Retrospective, single-centre observational design with potential for unmeasured confounding and selection bias.
  • Abstract does not report adjusted effect estimates (HRs and CIs) for smoking, sex, or inflamed margins, nor full list of covariates included in the final multivariable model.
  • Generalizability to other centres or practice eras may be limited given long accrual period (1995–2020) and evolving surgical/medical management.

3human in vivoEvaluate whether severe perioperative complications influence long-term surgical recurrence in the cohort.Retrospective single-centre cohortExpand

In plain English

In this retrospective single-centre cohort of 641 elective intestinal resections for Crohn's disease (1995–2020; mean follow-up 12.4 years), severe perioperative complications occurred in 7.0% overall (3.3% laparoscopic, 9.7% open) and were reported not to influence long-term surgical recurrence (p = 0.574).

Key findings

  • Severe perioperative complications occurred in 7.0% of patients (3.3% laparoscopic, 9.7% open) and were reported not to influence long-term surgical recurrence (p = 0.574).p = 0.574
“Severe perioperative complications (7.0% overall; 3.3% laparoscopic versus 9.7% open) did not influence recurrence (p = 0.574).”
What this piece can’t prove
  • Retrospective single-centre design as reported in abstract.
  • Lack of detail in abstract on how 'severe perioperative complications' were defined or ascertained.
  • Abstract does not specify the statistical model or covariates used when testing the association between severe complications and recurrence (only p-value reported).
  • Potential limited power to detect an association given low overall rate of severe complications (7.0%).
