目的:研究腹腔镜手术治疗高龄胆囊结石患者的临床疗效.方法:2010年4月-2019年4月收治高龄胆囊结石患者108例,分为两组,各54例.对照组采用传统开腹手术治疗;试验组采用腹腔镜手术治疗.比较两组临床疗效.结果:试验组平均手术时间、平均住院时间、平均术中出血量、平均肛门排气时间与术后并发症发生概率均显著低于对照组,差异均有统计学意义(P＜0.05).结论:与开腹手术相比,对高龄胆囊结石患者采用腹腔镜手术治疗,可以更好地提高临床疗效,降低并发症的发生概率,缩短住院时间.

目的:探究使用经皮经肝胆囊穿刺引流术的方式来治疗高危急性胆囊炎所产生的临床治疗效果.方法:随机选取我院2017年10月至2019年10月期间接受治疗的高危急性胆囊炎患者共60例,将其分成实验组和对照组,每组各30例.实验组的30例患者使用经皮经肝胆囊穿刺引流术后行手术治疗,对照组患者采取常规急诊手术进行治疗,对比两组患者手术治疗时间、术后住院治疗时间以及术后治疗效果.结果:实验组患者的手术治疗时间、术后住院治疗时间以及术后治疗效果均优于对照组,差异具有统计学意义(P＜0.05)结论:对高危急性胆囊炎患者行经皮经肝胆囊穿刺引流术进行治疗,可以大幅度的提高术后的治疗效果,并且有助于患者术后的身体恢复.

目的:对单孔腹腔镜在小儿腹股沟斜疝患儿手术治疗中的应用方式以及疗效进行详细探究.方法:选取2017年8月至2018年10月期间,本院收治的100例小儿腹股沟斜疝患儿作为研究对象,根据手术方案不同,将所有患儿分为对照组以及观察组,每组各50例.对于对照组患儿,采用传统开放手术治疗方案,对于观察组患儿,采用单孔腹腔镜疝囊高位结扎术治疗方案.对两组患儿的手术时间、术中出血量、住院时间以及术后并发症发生率进行详细记录并比较.结果:观察组患儿的手术时间以及住院时间短于对照组患儿,同时术中出血量少于对照组患儿.对照组患儿并发症发生率为(3/50)6.0％,观察组患儿并发症发生率为(1/50)2.0％,观察组患儿并发症发生率低于对照组患儿.结论:通过对小儿腹股沟斜疝患儿采用单孔腹腔镜疝囊高位结扎术治疗方案,疗效显著,同时患儿并发症发生率比较低,值得推广应用.

目的:讨论腹腔镜右半结肠切除术与开腹手术治疗结肠癌的临床治疗效果.方法:选取我院150例右半结肠癌患者作为本文的研究对象,而后以实施手术的不同,将这150例右半结肠癌患者分为对照组与研究各75例,对照组予以开腹手术,研究组予以腹腔镜右半结肠癌根治术,评判标准:各项手术指标、并发症.结果:研究组患者的各项手术指标与并发症发生情况明显优于对照组,两组数据相比有统计学差异,P＜0.05.结论:腹腔镜右半结肠癌根治术相较于开腹手术,更有利于促进患者的术后恢复,且并发症发生机率较低,值得在临床上进行推广.

Objective To evaluate short-time outcomes of laparoscopic surgery and open surgery (OS) for left-sided colon cancer. Methods Clinical data of 144 patients who received LAP or OS left hemicolectomy in Chinese Academy of Medical Science and Peking Union Medical College from January 2010 to March 2016 were collected and analyzed. These patients were divided into LAP group (n=66) and OS group (n=78). The operation time, intraoperative blood loss, the number of dissected lymph nodes and short-time outcomes were compared between two groups. Results There was a significant difference in operating time between the LAP group (151.36±26.98) min and the OS group (190.30±15.30) min (t=-5.130, P=0.0014). There was no significant difference in intraoperative blood loss between the LAP group (75±29.92) ml and the OS group (76.87±24.59) ml (t=-0.836, P=0.4613). There was a significant difference in length of surgical incision between the LAP group (6.88±3.00) cm and the OS group (15.57±2.22) cm (t=-28.484, P<0.001).There was no significant difference in number of swollen lymph nodes between the LAP group (21.58±8.57) and the OS group (23.82±10.96) (t=-0.283, P=0.2670). The average postoperative evacuation time (P=0.0015), getting out-of-bed time (P=0.0009), time to eat food (P=0.0018) were shorter in LAP group than in OS group.The hospital stays were shorter in LAP group than in OS group (t=-3.762, P=0.0364). there was no statistically significant difference between the two groups in postoperative complications (P=0.333). Conclusions LAP for left sided colon cancer is safe and reliable. Compared to the OS group, LAP has advantages including less surgery time, smaller surgical incision, faster recovery and shorter hospital stays.
