Laparoscopic Right Hemicolectomy with Radical Lymph Node Dissection Using the No-Touch Isolation Technique for Advanced Colon Cancer

The treatment of advanced right-sided colon cancer presents numerous challenges for the surgeon who must aim to minimize the invasiveness of surgery, achieve curative resection, and prevent port-site recurrences. To overcome these issues, we performed a totally intra-abdominal laparoscopic right hemicolectomy with radical lymph node dissection based on a no-touch isolation technique. To perform this no-touch technique, we initially dissected the lymph nodes along the surgical trunk, then transected the transverse colon, terminal ileum, and mesentery without tumor manipulation. Finally, the right side of the colon was freed retroperitoneally. We performed this surgical technique on three patients and no intraoperative complications were encountered. Curative resection was achieved in all three patients, as curability A according to the Japanese Classification of Colorectal Carcinoma, and their postoperative courses were uneventful. Therefore, this novel technique proved to be both feasible and safe. Furthermore, it enabled us to minimize the invasiveness of surgery, while providing clear access to resect the right-sided advanced colon cancer.

前入路原位胰十二指肠切除术治疗胰头癌的临床疗效

目的探讨前入路原位胰十二指肠切除术(PD)治疗胰头癌的临床疗效。方法采用回顾性队列研究方法。收集2012年1月至2018年6月昆明医科大学第一附属医院收治的285例胰头癌患者的临床病理资料;男164例,女121例;平均年龄为57岁,年龄范围为40~76岁。285例患者中,196例行前入路原位PD,设为前入路组;89例行传统入路PD,设为传统入路组。观察指标:(1)手术情况。(2)术后情况。(3)随访情况。采用门诊、电话或网络方式进行随访,术后每2~3个月门诊随访1次,了解患者肿瘤复发、转移及生存情况。随访终点为患者死亡,随访次要终点为肿瘤复发或转移。随访时间截至2018年12月。正态分布的计量资料以±s表示,组间比较采用t检验。偏态分布的计量资料以M(范围)表示,组间比较采用Mann-Whitney U检验。计数资料以绝对数或百分比表示,组间比较采用χ2检验。采用Kaplan-Meier法绘制生存曲线,采用Log-rank检验进行生存分析。结果(1)手术情况:285例患者均顺利完成手术。前入路组患者保留幽门,联合门静脉-肠系膜上静脉切除重建(对端吻合、人工血管置换、侧壁切除吻合),手术时间,术中出血量分别为118例,37例(17、11、9例),(303±107)min,350 mL(100~750 mL);传统入路组患者上述指标分别为48例,9例(7、1、1例),(335±103)min,400 mL(100~900 mL),两组患者上述指标比较,差异均无统计学意义(χ2=0.990,3.474,t=0.722,Z=1.729,P>0.05)。(2)术后情况:前入路组患者R0切除率、淋巴结清扫数目、阳性淋巴结清扫数目、神经侵犯率、脉管侵犯率、严重并发症、围术期死亡、术后化疗分别为93.88%(184/196)、12枚(5~19枚)、4枚(0~15枚)、45.41%(89/196)、31.12%(61/196)、28例、3例、69例;传统入路组患者上述指标分别为85.39%(76/89)、7枚(4~17枚)、5枚(0~13枚)、32.58%(29/89)、23.60%(21/89)、11例、2例、41例,两组患者R0切除率、淋巴结清扫数目、神经侵犯率比较,差异均有统计学意义(χ2=5.506,Z=4.637,χ2=4.149,P<0.05);两组患者阳性淋巴结清扫数目、脉管侵犯率、严重并发症、围术期死亡、术后化疗比较,差异均无统计学意义(Z=0.052,χ2=1.962,0.192,0.001,3.048,P>0.05)。(3)随访情况:285例患者中,252例完成次要终点随访,228例完成终点随访,随访时间为35个月(6~58个月)。196例前入路组患者中,181例完成次要终点随访,176例完成终点随访,随访时间为38个月(6~58个月);89例传统入路组患者中,71例完成次要终点随访,52例完成终点随访,随访时间为33个月(7~53个月)。前入路组患者术后中位无瘤生存时间、中位总体生存时间分别为31个月、37个月,传统入路组患者上述指标分别为24个月、31个月,两组患者术后无瘤生存比较,差异有统计学意义(χ2=7.646,P<0.05),术后总体生存比较,差异无统计学意义(χ2=3.265,P>0.05)。结论前入路原位PD治疗胰头癌安全、可行,能提高手术R0切除率,延长患者无瘤生存时间。
