METHODS: The patient was a 73-year-old woman diagnosed with ascending colon cancer on colonoscopy. Preoperative abdominal contrast-enhanced computed tomography confirmed that the MCA and ICA had a common trunk. She underwent laparoscopic ileocecal resection for the ascending colon cancer with D3 lymph node dissection. Intraoperative indocyanine green fluorescence imaging was conducted. After confirming vessel bifurcation, the ICA was dissected at the distal end of the MCA bifurcation. The patient has been followed as an outpatient, with no signs of recurrence as of 2 years postoperatively.
CONCLUSIONS: A case of an ascending colon cancer with a unique vascular bifurcation pattern was presented. Preoperative and intraoperative evaluations of the major colorectal vessels are very important for preventing perioperative and postoperative complications.
方法:患者是一名73岁女性,在结肠镜检查中被诊断为升结肠癌。术前腹部对比增强计算机断层扫描证实,MCA和ICA具有共同的躯干。她接受了腹腔镜回盲肠切除术治疗升结肠癌,并进行了D3淋巴结清扫。术中进行吲哚菁绿荧光成像。确认血管分叉后,在MCA分叉的远端解剖ICA。该患者已作为门诊病人被随访,术后2年无复发迹象。
结论:呈现一例具有独特血管分叉模式的升结肠癌。术前和术中评估结直肠主要血管对于预防围手术期及术后并发症非常重要。
