直肠海绵状血管瘤是一种罕见的良性血管疾病，很少引起下消化道出血，其特点是误诊和漏诊率较高。手术治疗被认为是相对有效的；但它同时也应用于浅表血管瘤的治疗，具有微创手术的优点，包括安全、有效、创伤小、恢复快等。但目前尚缺乏泡沫硬化剂治疗胃肠道血管瘤的文献。现报道一例60岁男性，因反复便血病史>1年，症状加重而入院。 1周。患者病史无异常，经结肠镜、核磁共振、CT等检查，最终诊断为直肠海绵状血管瘤。因患者拒绝手术，在了解情况后进行了内镜下聚桂醇注射液泡沫硬化治疗。经患者及其亲属同意。硬化治疗后，便血症状消失，未观察到不良反应。两个月后，结肠镜检查和核磁共振显示血管瘤几乎完全消失，只有少量肿瘤残留，疗效满意。我们的研究结果表明，内镜下注射聚桂醇泡沫硬化剂是一种安全、有效的方法。胃肠道海绵状血管瘤的有效微创治疗选择。版权所有 © 2024 作者。由 Wolters Kluwer Health, Inc. 出版

Rectal cavernous hemangioma is a rare, benign vascular disease that seldom causes lower gastrointestinal bleeding, characterized by a high rate of misdiagnosis and missed diagnoses. Surgical treatment is considered to be relatively effective; however, it is accompanied by certain employed in the treatment of superficial hemangioma, boasting the advantages of minimally invasive surgery, including safety, effectiveness, reduced trauma, and rapid recovery. However, there is a lack of literature regarding the application of foam sclerosing agents for gastrointestinal hemangiomas.We present a case of a 60-year-old male who was admitted to our hospital with a history of recurrent hematochezia for >1 year and worsening symptoms for 1 week. The patient's medical history was unremarkable.Following colonoscopy, nuclear magnetic resonance imaging, computed tomography, and other examinations, the final diagnosis was rectal cavernous hemangioma.Due to the patient's refusal of surgery, endoscopic foam sclerotherapy using a lauromacrogol injection was performed after obtaining informed consent from the patient and their relatives.Post-sclerotherapy, hematochezia symptoms ceased, and no adverse reactions were observed. Two months later, colonoscopy and nuclear magnetic resonance imaging showed that the hemangioma had almost completely disappeared, with only a small amount of tumor remnants, yielding a satisfactory curative effect.Our findings indicate that endoscopic injection of a lauromacrogol foam sclerosing agent is a safe, effective, and minimally invasive treatment option for gastrointestinal cavernous hemangiomas.Copyright © 2024 the Author(s).
