Epidemiological and clinical profile of patients with liver hydatid cyst in an endemic region.
Observational study in BMC surgery, 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
backgroundLiver hydatid cyst can be found anywhere in the world, but especially in endemic areas, including Iraq. However, its epidemiology and clinical patterns are different among various populations in other countries.
objectiveTo find out the epidemiological and clinical profile of patients with liver hydatid cyst in our locality (endemic area). PATIENTS AND
methodsThis observational cross-sectional study was conducted on a total of 250 patients diagnosed with liver hydatid cysts at multiple hospitals, Sulaimaniyah, Iraq, from January 2022 to March 2025. All patients underwent partial cystectomy for liver hydatid cyst under general anesthesia. A self-created questionnaire was used to collect patients’ data on their sociodemographic characteristics, environmental factors, risk factors, and the recurrence of liver hydatid cyst. Then, correlations between some variables were determined and compared.
resultsThe mean age of the patients was 39.49 ± 17.97 years. Majority of the patients were aged < 30 years (33.2%), females (60.4%), lived in rural areas (60.8%), had direct contact with livestock (55.2%) and dogs (59.2%), used spring water as their primary water source (56.8%), and did not have any family members diagnosed with hydatid cyst (92%). Among patients, only 19.6% experienced a postoperative bile leak that was significantly associated with cyst size (≥ 6 mm) (p = 0.004) and multiple cyst (p < 0.001) after adjustment of the data. More profound symptoms among patients was right upper quadrant pain (68.8%), while some individuals had jaundice, nausea and vomiting. Also, most patients (95.2%) did not experience any recurrence.
conclusionsPostoperative bile leak was significantly associated with cyst size, number of cysts, and affected liver segment. Hospital stay was longer among patients with postoperative bile leak.
