吲哚菁绿引导腹腔镜淋巴结切除术治疗根治性前列腺切除术后直肠系膜内淋巴结转移2例报告

Indocyanine green guided laparoscopic lymphadenectomy for the treatment of intramesorectal lymph node metastasis after radical prostatectomy:2 cases

前列腺癌根治性手术后直肠系膜内淋巴结转移在临床上少见。本文报道2例根治性前列腺切除术后直肠系膜内淋巴结转移行手术切除的病例。例1行腹腔镜根治性前列腺切除术后5年,复查MRI发现直肠系膜淋巴结转移。例2行机器人辅助腹腔镜根治性前列腺切除术后2个月,复查盆腔MRI发现直肠系膜淋巴结转移。2例患者均接受吲哚菁绿荧光引导腹腔镜直肠系膜淋巴结切除术。术后4~6个月复查血清PSA及MRI,未见肿瘤复发。

Intramesorectal lymph node metastasis after radical surgery of prostate cancer is rare in clinical practice.This paper reported 2 cases of intramesorectal lymph node metastasis and resection after operation for prostate cancer.Patient 1 underwent laparoscopic radical prostatectomy 5 years ago,who was followed up closely after surgery,and was diagnosed with mesorectal lymph node metastasis by MRI examination.Patient 2 underwent robot-assisted laparoscopic radical prostatectomy 2 months ago,who was followed up by pelvic MRI and mesorectal lymph node metastasis was revealed.Both patients underwent fluorescence laparoscopic mesenteric lymphadenectomy in our department.With 4 to 6 month of follow-up after surgery,MRI examination showed no recurrence of tumor.
