Neutropenic enterocolitis (NEC) can be a life-threatening complication of chemotherapy in leukemic patients. Early diagnosis and treatment is therefore crucial.
A 38-year-old woman with acute lymphoblastic leukemia and chemotherapy-induced neutropenia suddenly developed symptoms suspicious of NEC. Transabdominal ultrasound showed features consistent with NEC, later confirmed by computed tomography (CT) scan.
The patient was scanned using portable ultrasound (US) equipment (Esaote My Lab 25). US findings showed involvement of the cecum, appendix, ascending colon and proximal middle transverse colon, with features resembling gas containing fissures within the colon wall itself. The risk of colon rupture was confirmed by CT scan. The patient underwent successful hemicolectomy after intravenous treatment with broad spectrum antibiotics, granulocyte-colony stimulating factor (G-CSF), platelets and fresh frozen plasma transfusion.
A prompt bedside US examination upon development of symptoms allowed an early diagnosis of NEC and identified features consistent with imminent colon wall rupture, shifting the management of this life-threatening complication from medical to surgical. Multidisciplinary intervention was crucial for a successful hemicolectomy in a severely affected neutropenic patient.
中性粒细胞减少性小肠结肠炎(NEC)可能是白血病患者化疗过程中一种危及生命的并发症。因此,早期诊断和治疗至关重要。
一名38岁急性淋巴细胞白血病且化疗导致中性粒细胞减少的女性突然出现疑似NEC的症状。经腹超声显示的特征与NEC相符,随后计算机断层扫描(CT)证实了这一诊断。
使用便携式超声(US)设备(百胜My Lab 25)对患者进行扫描。超声检查结果显示盲肠、阑尾、升结肠和近端中横结肠受累,其特征类似于结肠壁内含有气体的裂隙。CT扫描证实了结肠破裂的风险。患者在接受广谱抗生素、粒细胞集落刺激因子(G-CSF)、血小板静脉治疗及新鲜冰冻血浆输注后,成功接受了半结肠切除术。
症状出现后立即进行床旁超声检查可早期诊断NEC,并识别出与即将发生的结肠壁破裂相符的特征,从而将这种危及生命的并发症的治疗从内科转为外科。多学科干预对于严重中性粒细胞减少患者成功实施半结肠切除术至关重要。
