To assess safety of rectum removal with distal sacral resection.
The short-term results of surgical treatment of primary and recurrent locally advanced rectal and anal cancer with sacral fixation have been analyzed. 32 patients underwent combined operations with sacral resection at the level of S2-S5. In 12 patients only one point of tumor fixation (F1) was revealed, 10 patients had two points of fixation (F2), three patients had three fixation points (F3) and in 7 cases the tumor was fixed to four points (F4) of fixation to different pelvic structures.
Mean intraoperative blood loss and surgery time was 551±81 ml and 320±20 min in cases of sacral fixation only that was significantly lower compared with F2 cases - 1278±551 ml and 433±45 min, F3 cases - 2200±600 ml and 620±88 min, F4 cases - 2157±512.5 ml and 519±52,3 min, respectively (р<0.05). Complications requiring surgical intervention occurred in 9% patients (n=3). Among 23 patients with intact bladder and ureters urinary disorders occurred in 42% (n=10). Resection margin was negative along posterior surface of the specimen in all cases.
Advanced surgery with distal sacral resection is advisable for radical removal of locally advanced and recurrent rectal and anal canal cancer fixed to the sacrum with negative resection margin. These operations are feasible in specialized centers and should be performed by specially trained oncological or colorectal surgeon.
评估低位骶骨切除直肠切除术的安全性。
分析了采用骶骨固定术治疗原发性和复发性局部晚期直肠癌和肛管癌的手术短期结果。32例患者接受了S2 - S5水平的骶骨切除术联合手术。12例患者仅发现一个肿瘤固定点(F1),10例患者有两个固定点(F2),3例患者有三个固定点(F3),7例患者肿瘤固定于不同盆腔结构的四个固定点(F4)。
仅行骶骨固定术的患者术中平均失血量和手术时间分别为551±81 ml和320±20分钟,与F2组(1278±551 ml和433±45分钟)、F3组(2200±600 ml和620±88分钟)、F4组(2157±512.5 ml和519±52.3分钟)相比显著更低(р<0.05)。9%(n = 3)的患者发生了需要手术干预的并发症。在23例膀胱和输尿管未受侵犯的患者中,42%(n = 10)出现了泌尿系统疾病。所有病例标本后表面的切缘均为阴性。
对于根治性切除固定于骶骨的局部晚期和复发性直肠癌及肛管癌且切缘阴性,采用低位骶骨切除术的根治性手术是可取的。这些手术在专业中心是可行的,应由经过专门培训的肿瘤外科医生或结直肠外科医生进行。
