This study aims to compare the operative results and oncological outcomes of patients with total mesorectal excision (TME) for mid and distal cancer and partial mesorectal excision (PME) for proximal cancer. Anterior resection has become the preferred treatment option for rectal cancer. TME with sharp dissection has been shown to be associated with a low local recurrence rate. Controversies still exist as to the need for TME in more proximal tumor. Resection of primary rectal and rectosigmoid cancer was performed in 298 patients from January 2003 to November 2010. These 298 patients (163 men and 135 women; median age, 67 years) underwent anterior resection. The curative resection was performed in 269 patients (90.3 %). TME was performed in 202 patients (67.8 %). Significantly longer median operating time, more blood loss, and a longer hospital stay were found in patients with TME. The overall operative mortality and morbidity rates were 1.8 % and 32.6 %, respectively, and there were no significant differences between those of TME and PME. Anastomotic leak occurred in 8.1 % and 1.3 % of patients with TME and PME, respectively (P < 0.001). Independent factors for a higher anastomotic leakage rate were TME, the malegender, the absence of stoma, and increased blood loss. The advanced stage of the disease and the performance of coloanal anastomosis were independent factors for increased local recurrence. By performing TME in patients with mid and distal rectal cancer, the local control and survival of these patients are similar to those of patients with proximal cancers where adequate clearance can be achieved by PME.
本研究旨在比较接受全直肠系膜切除术(TME)治疗的中低位直肠癌患者与接受部分直肠系膜切除术(PME)治疗的高位直肠癌患者的手术结果和肿瘤学结局。前切除术已成为直肠癌的首选治疗方式。锐性分离的TME已被证明与低局部复发率相关。对于更高位肿瘤是否需要TME仍存在争议。2003年1月至2010年11月,对298例原发性直肠和直肠乙状结肠癌患者进行了手术切除。这298例患者(163例男性和135例女性;中位年龄67岁)接受了前切除术。269例患者(90.3%)进行了根治性切除。202例患者(67.8%)接受了TME。TME患者的中位手术时间明显更长、失血量更多、住院时间更长。总体手术死亡率和发病率分别为1.8%和32.6%,TME组和PME组之间无显著差异。TME组和PME组患者吻合口漏发生率分别为8.1%和1.3%(P<0.001)。吻合口漏率较高的独立因素为TME、男性、未行造口术和失血量增加。疾病晚期和结肠肛管吻合术的实施是局部复发增加的独立因素。对中低位直肠癌患者实施TME,这些患者的局部控制和生存率与高位直肠癌患者相似,后者通过PME可实现充分的切缘。
