Objective To investigate the safety and feasibility of the total mesorectal excision (TME) and intersphincteric resection (ISR) for ultra-low rectal cancer and anal sphincter preservation surgery for anorectal cancer, and to evaluate the short term efficacy and postoperative anal function. Methods A retrospective analysis of clinical and follow-up data of 86 cases with TME+ISR for ultra-low rectal cancer and anorectal cancer from January 2009 to December 2010 in West China Hospital of Sichuan University were performed. Results Eighty-six patients were successfully performed the operation, the lower edge of tumor from the anus was 1-5 cm (average 1.63cm); tumor diameter was 2-7 cm (average 3.4cm). The tumors were high differentiation in 4 cases, moderately differentiation in 60 cases,and poorly differentiation in 22 cases. The pTNM stages were stageⅠin 12 cases, stageⅡA in 11 cases, stage ⅡB in 15 cases, stage ⅢA in 2 cases, stage ⅢB in 23 cases, stage ⅢC in 16 cases, and stage Ⅳ in 7 cases. There were postoperative anastomotic leakage in 3 cases, perianal infection in 2 cases (1 case received reoperation with permanent colostomy because of pelvic peritoneal infection caused by perianal severe infections). Anastomotic bleeding and anastomotic stenosis were of 2 cases respectively. Rectovaginal fistula, inflammatory ileus, urinary retention, and abdominal infection were of 1 case respectively. Eighty-six patients were followed-up for 12-24 months, the mean time was 18 months. Liver metastases was found in 1 case in 7 months after operation, 2 cases dead in the 7th month and 12th month after operation respectively. Local recurrence were found in 3 cases (3.5%) in 1 year after operation. The survival rate of 1-year was 97.7% (84/86). The times of defecation was 1-5 times a day. The Kirwan’s score level on function of control defecation was 1-2 grade. Conclusions TME+ISR for low rectal cancer and anorectal cancer is a viable, safe, and radical operation type for preservation of anus. The short term efficacy is satisfactory.
目的 探讨肛管拖出式双吻合器在超低位直肠癌保肛手术中的应用价值。方法 回顾性总结我院23例超低位直肠癌保肛手术的经验。结果 本组病例利用肛管拖出和双吻合器技术行超低位保肛术均获成功,术后发生吻合口漏1例(4.3%),切口感染2例(8.7%),术后局部复发2例(8.7%),无手术死亡。结论 肛管拖出式双吻合器技术行超低位保肛术是安全可靠的,它可以大大提高超低位直肠癌保肛手术的成功率。
Objective To evaluate the role of curved-cutter-stapler in anus-preserving for low rectal cancer. Methods The clinical data of 32 patients with low rectal cancer from June 2007 to December 2008 who received low anterior resection and ultra low anterior resection by using curved-cutter-stapler were reviewed retrospectively. Results No operation death case, complete cutting and safe closure in all cases, one case was complicated with anastomotic leakage, and one case of rectovaginal fistula. Thirty patients were followed up 4 to 22 months after the operation, with an average time of 12.6 months, no hemorrhea of pelvic cavity and anastomotic stoma or anastomotic stenosis cases. Conclusion Curved-cutter-stapler has the advantages of complete cutting, safe closure and low complications, and easy being used in anus-preserving operation for low rectal cancer, which can increase the rate of anus-preserving.
目的 探讨国产单吻合器在低位直肠癌保肛手术中的临床应用效果。方法 结合相关文献回顾性分析2003年1月至2007年12月期间我院收治的128例低位直肠癌中行直肠全系膜切除(TME)且应用国产管状吻合器及荷包钳进行手术的91例患者的资料。结果 全组无手术死亡病例,保肛均获成功,保肛率为71.09%(91/128),术后病理检查肿瘤远端切缘无癌残留。未发生吻合口出血及狭窄; 1例(1.10%)发生吻合口漏,经保守治疗后痊愈; 无大便失禁发生。全组获随访1~5年,平均3.8年,局部复发6例(6.59%); 总的1年生存率为97.80%(89/91),3年生存率为80.00%(72/90),5年生存率为68.97%(60/87)。结论 TME联合国产管状吻合器及荷包钳应用于低位直肠癌根治术,可提高保肛率,操作简单安全,疗效满意。
目的 评价超低位直肠癌保肛手术的安全性和疗效。方法 回顾性分析笔者所在医院2004年10月至2010年12月期间收治的48例行管扎式结肠肛管吻合术的超低位直肠癌患者的临床资料。结果 48例患者手术均获成功,手术时间120~221min,(178±37) min; 术中出血量70~210mL,(167±38) mL; 术后排气时间2~5d,(3.1±1.2) d; 术后排便时间8~11d,(9.1±1.4) d。保留完整齿状线者27例,保留齿状线≥1/2者14例,保留齿状线<1/2者7例。所有患者均获随访,随访时间1~7年,平均32个月。术后有3例患者发生吻合口狭窄,无吻合口漏发生。术后1年有25例患者的肛门括约肌功能达优,其中保留完整齿状线者18例,保留齿状线≥1/2者7例; 良好16例,其中保留完整齿状线者9例,保留齿状线≥1/2者7例; 一般7例,均为保留齿状线<1/2的患者,优良率为85.4%(41/48)。随访期间,2例患者分别于术后9个月和13个月直肠癌局部复发,其中1例于术后23个月死亡。结论 超低位直肠癌保肛手术是一种安全的、可行的手术方式,可以在根治的前提下达到保肛的目的。
目的 探讨腹腔镜超低位直肠癌保肛手术的可行性。方法 回顾性总结2004年9月至2007年10月期间行腹腔镜超低位直肠癌保肛手术58例患者的临床资料。结果 54例在腹腔镜下顺利完成手术,中转开腹4例,无手术死亡病例。平均手术时间187 min,术中平均失血110 ml,术后肛门排气时间平均为2.3 d。手术切除淋巴结平均为18.5个; 随访6~42个月(平均17.6个月)未见切口种植及吻合口复发。结论 腹腔镜超低位直肠癌保肛手术具有创伤小、术后恢复快等优点,可以取得比开腹手术更好的根治效果。
