Treatment and analysis of a case of pulmonary embolism with pulmonary infarction following mixed haemorrhoid surgery case report.
Article in Medicine, 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
rationalePulmonary embolism following mixed hemorrhoid surgery is uncommon, with few such cases reported in domestic and international literature. This study examines the clinical characteristics, diagnosis, treatment, and outcomes of pulmonary artery embolism after mixed hemorrhoid surgery, aiming to enhance clinicians' vigilance and prevention of postoperative complications. PATIENT CONCERNS: Clinical features of a patient with pulmonary embolism following mixed hemorrhoid surgery, admitted to the Department of Anorectal Surgery at Ansteel General Hospital in June 2025, were analyzed. A 55-year-old female presented with a rectal mass protruding after defecation for approximately 2 weeks. Denies a history of hypertension or diabetes; denies a history of infectious diseases such as hepatitis or tuberculosis; no history of surgery or trauma; no history of varicose veins or swelling and pain in both lower extremities; no history of cardiovascular or cerebrovascular disease or thrombosis; and has had sleep disturbances for over a year. She underwent mixed hemorrhoid surgery on June 24, 2025 and was discharged uneventfully. Five days later, the patient presented to our hospital's respiratory medicine department with sudden right-sided chest pain accompanied by dry cough. Pulmonary computed tomography (CT) angiography revealed pulmonary embolism with pulmonary infarction. Abnormalities in D-dimer, fibrinogen, and blood gas analysis. DIAGNOSES: Combined with the patient's symptoms and physical findings, led to a definitive diagnosis of pulmonary embolism with pulmonary infarction following mixed hemorrhoid surgery.
interventionsFollowing oxygen therapy, anti-inflammatory treatment, and anticoagulation, a follow-up pulmonary CT scan demonstrated reduced pulmonary infarction with improved lesion margins. OUTCOMES: Prognosis is favorable, with the patient currently undergoing regular follow-up. LESSONS: Although the risk of pulmonary embolism following hemorrhoid surgery is low, if it does occur and is not promptly diagnosed and treated, the consequences are often severe and may even be life-threatening. This article presents the diagnostic and treatment process for this case and provides analysis and discussion in conjunction with related cases, with the aim of providing some advice for the timely diagnosis and treatment of pulmonary embolism following colorectal surgery.
