目的:探讨三联预康复策略在肝癌腹腔镜肝切除术中的应用价值。方法:选取2015年1月至2018年1月四川大学华西医院胆道外科收治的120例行腹腔镜肝切除术的肝癌患者，按随机数字表法分为观察组及对照组各60例。观察组在门诊收治当日开始三联预康复策略干预，干预时间约2～4周；对照组予以常规肝癌腹腔镜肝切除术术前准备。于干预前、术前1天及术后4周分别记录六分钟步行距离(6MWT)、医院焦虑抑郁量表(HADS)评分、健康调查简表(SF-36)评分及检测血清白蛋白(ALB)、前白蛋白(PA)、转铁蛋白(TRF)水平。结果:术前1天，观察组6MWT、血清ALB、PA、TRF水平高于干预前(P＜0.05)；对照组6MWT、血清ALB、PA、TRF水平与干预前差异无统计学意义(P＞0.05)；术后4周，观察组6MWT、血清ALB、PA、TRF水平与干预前差异无统计学意义(P＞0.05)；对照组6MWT、血清ALB、PA、TRF水平低于干预前(P＜0.05)；术前1天、术后4周观察组HADS评分低于干预前，SF-36评分高于干预前(P＜0.05)；对照组HADS、SF-36评分与干预前差异无统计学意义(P＞0.05)；术前1天、术后4周，观察组6MWT、SF-36评分、血清ALB、PA、TRF水平高于对照组，HADS评分低于对照组(P＜0.05)。结论:三联预康复策略应用于肝癌腹腔镜肝切除术可明显改善患者围术期活动能力、心理状态及营养状况，加速患者术后恢复。     

腹腔镜与开腹手术治疗子宫内膜癌的疗效比较

目的:探讨腹腔镜与传统开腹手术治疗子宫内膜癌的临床效果差异。方法:回顾性分析陕西省人民医院2013年10月至2018年3月114例确诊为子宫内膜癌并以腹腔镜治疗的患者为研究对象（腹腔镜组），以同期62例开腹手术治疗的子宫内膜癌病例为对照组，两组在手术时间、术中出血量、淋巴结清扫个数、术后膀胱功能恢复时间、排气时间、体温恢复时间、住院时间及并发症等各方面指标进行比较。结果:腹腔镜组术中失血量、输血率、术后体温恢复时间、肠道功能恢复时间、膀胱功能恢复时间、术后住院天数及手术并发症发生率显著低于开腹组(P<0.05)。腹腔镜组与开腹组在手术时间、术中清扫淋巴结数目、复发率及总生存率差异无统计学意义。结论:与传统方法相比，腹腔镜手术短期效果良好，生存率相当，在具备丰富的腹腔镜手术经验、完善的腹腔镜设备的条件下，可以广泛应用于子宫内膜癌患者的治疗。     

RPLU、FURL及PCNL治疗输尿管上段嵌顿性结石的疗效研究

目的探讨后腹腔镜切开取石术（retroperitoneal laparoscopic lithotomy，RPLU）、输尿管软镜碎石清石术（lithotripsy with flexible ureteroscope，FURL）及经皮肾镜碎石清石术（percutaneous nephrolithotomy，PCNL）种不同方法治疗输尿管上段嵌顿性结石的疗效，以明确直径大于1.5 cm的输尿管上段嵌顿性结石的最佳处理方案。 方法回顾性分析159例输尿管上段嵌顿性结石，收集其术前术中资料，按术式不同分为RPLU组56例、FURL组55例、PCNL组48例。对手术时间、术后住院时间、结石清除率、术后并发症等数据进行统计学分析。 结果FURL组手术时间和术后住院时间明显短于RPLU组和PCNL组，差异均有统计学意义（P＜0.05）。RPLU组术后3 d和术后1个月的结石清除率（100%，100%）稍高于FURL组（90.9%，94.5%）和PCNL组（93.8%，93.8%），3组患者术后无严重并发症出现，差异均无统计学意义（P＞0.05）。 结论3种不同手术方法治疗嵌顿性输尿管上段结石均安全有效，FURL组手术时间及住院时间更短，患者术后恢复更快，更具有优势。     

自制极简PORT在单孔腹腔镜子宫肌瘤切除术中的应用初步探讨

目的:初步探讨自制极简入路通道（PORT）在单孔腹腔镜子宫肌瘤切除术中应用的可行性及安全性。方法:回顾性分析空军军医大学西京医院妇产科于2017年3月至2018年12月共完成的46例单孔腹腔镜子宫肌瘤切除术患者，其中24例使用商品化PORT，22例使用我科自制极简PORT，所有患者均配合使用常规腹腔镜器械顺利完成手术。比较两组患者年龄、体质量数、手术时间、术中出血量、子宫肌瘤直径、术中及术后相关并发症、手术前后血红蛋白差值、术后排气时间、术后疼痛模拟评分、住院时间、术后随访情况等指标。结果:所有患者均顺利完成手术，无中转开腹或增加穿刺孔，无并发症发生。商品化PORT组和自制极简PORT组患者的一般资料具有可比性。手术相关指标包括手术时间［（75±56.9）min vs （74±55.7）min］、术中出血量［（55±67.9）ml vs （56±65.8）ml］、子宫肌瘤直径［（6±2.8）cm vs （6±3.4）cm］，两组比较无明显统计学差异（P＞0.05）。术后恢复指标包括术后排气时间［（12.6±4.4）h vs （13.5±3.4）h］、术后疼痛模拟评分［（2.1±1.3）分 vs （2.0±1.2）分］、住院时间［（3.4±2.8）d vs （3.5±2.6）d］，同样无统计学差异（P＞0.05）。两组手术效果相同，但术中使用自制极简PORT几乎不增加耗材。结论:自制极简PORT在单孔腹腔镜子宫肌瘤切除术中的应用安全性好，效果确切，节约成本，值得推广。     

Effects of Single-Dose Preemptive Pregabalin and Intravenous Ibuprofen on Postoperative Opioid Consumption and Acute Pain after Laparoscopic Cholecystectomy

Purpose: Non-opioid medications as a part of multimodal analgesia has been increasingly suggested in the management of acute post-surgical pain. The present study was planned to compare the efficacy of the combination of pregabalin plus ?v ibuprofen. Methods: 58 patients were included in this prospective, randomized, double-blinded study. The pregabalin group (Group P, n = 29) received 150 mg pregabalin, the pregabalin plus ibuprofen group (Gropu PI, n = 29) received 150 mg pregabalin and 400mg ?v ibuprofen before surgery. Postoperative fentanyl consumption, additional analgesia requirements and PACU stay were recorded. Postoperative analgesia was performed with patient-controlled IV fentanyl. Results: VAS scores in the group PI were statistically lower at PACU, 1and 2 hours at rest, at PACU, 1, 2, 4, 12 and 24 hours on movement compared to the group P (P < 0.05). Opioid consumption was statistically significantly higher in the group P compared to the group PI (130.17 ± 60.27 vs 78.45 ± 60.40 μq, respectively, P < 0.001) and reduced in the 4th 24 hours by 55% in group PI. Rescue analgesia usage was statistically significantly higher in the group P than in the group PI (16/29 vs 7/29, respectively, P < 0.001). Four patient in the group PI did not need any opioid drug. Besides, PACU stay was shorter in the group PI than the group P (10.62 ± 2.38 vs 15.59 ± 2.11 min, respectively, P < 0.001). Conclusion: Preemptive pregabalin plus ?v ibuprofen in laparoscopic cholecystectomy reduced postoperative opioid consumption. This multimodal analgesic aproach generated lower pain scores in the postoperative period.     

Preservation of Denonvilliers' fascia for nerve‐sparing laparoscopic total mesorectal excision: A neuro‐histological study

Urogenital complications due to pelvic autonomic nerve damage frequently occur following rectal surgery. We investigated whether total mesorectal excision (TME) with preservation of the Denonvilliers' fascia (DVF) can effectively prevent the removal of pelvic autonomic nerves through microscopy. Twenty consecutive male patients with mid‐low rectal cancer who received TME with preservation or resection of the Denonvilliers' fascia (P and R groups, respectively) were included. Serial transverse sections from surgical specimens were studied histologically. Nerve fibers at the surfaces of the mesorectum were counted. Clinical correlation between the amount of nerve fibers removed and post‐operative sexual function was analyzed. Nerve fibers closely localized to the DVF in the R group displaying rich erectile activity (positive anti‐nNOS immunostaining). At the anterior surface of the mesorectum, the mean numbers of nNOS‐positive nerve fibers per specimen in the P group were significantly lower than the R group (3.0 ± 1.8 vs. 5.0 ± 2.3, P < 0.05). Compared to the R group, patients in the P group had higher IIEF scores and better erectile function at 3 and 6 months post‐operatively. The DVF is a key risk zone for pelvic denervation during laparoscopic TME. Preservation of the DVF can prevent the removal of autonomic nerves and protect post‐operative erectile function. Clin.
