Texas statewide incidence and severity of iatrogenic major vascular injury during inpatient laparoscopic surgery: a population-based cohort study.
Article in Surgical endoscopy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMajor vascular injury during laparoscopic surgery is rare but potentially catastrophic. Existing literature is largely limited to case series and registry-based analyses without reliable denominators or validated measures of disease severity. Procedure-specific risk and overall population burden remain incompletely defined. This study aimed to determine the statewide incidence, severity profile, and procedure-specific risk of iatrogenic major vascular injury during inpatient laparoscopic surgery.
methodsWe conducted a retrospective population-based cohort study using the 2024 Texas Inpatient and Outpatient Public Use Data File (PUDF). Adult patients (≥ 18 years) undergoing inpatient laparoscopic procedures were identified using ICD-10-PCS approach codes. Iatrogenic major vascular injury was defined using ICD-10-CM diagnosis codes T81.71* and/or I97.5*. The primary outcome was statewide incidence per 10,000 inpatient laparoscopic procedures. Secondary outcomes included markers of clinical severity, including mortality, ICU admission, conversion to open surgery, transfusion, organ failure, and length of stay.
resultsAmong 119,652 inpatient laparoscopic procedures, 84 cases of iatrogenic major vascular injury were identified, yielding an incidence of 7.02 per 10,000 procedures. (R3C3) These injuries were associated with high clinical severity, including an in-hospital mortality rate of 7.2% and ICU admission in 66.3% of cases. Surgical management often required escalation, with 55.4% of cases undergoing conversion to open surgery and 30.1% requiring blood transfusion. Acute kidney injury (26.5%) and respiratory failure (24.1%) were common. The median length of stay was 6 days (IQR 3-11), compared with 3 days (IQR 1-5) without injury. Diagnostic laparoscopy demonstrated the highest incidence (20.59 per 10,000), whereas colorectal resection had the lowest (0.89 per 10,000).
conclusionsIatrogenic major vascular injury during inpatient laparoscopic surgery was rare but associated with substantial morbidity and mortality. The elevated incidence observed during diagnostic laparoscopy may suggest abdominal access as an important contributing mechanism of injury, reinforcing the need for continued emphasis on safe-entry techniques and heightened specialty-specific risk awareness.
