结直肠癌肝转移患者行全腹腔镜与腹腔镜辅助同期切除手术的疗效观察

目的探讨结直肠癌肝转移(CRLM)患者采用全腹腔镜与腹腔镜辅助同期切除术治疗的临床疗效比较。方法选取2010年2月至2015年4月间大连大学附属新华医院收治的68例CRLM同期切除患者,采用随机数表法分为辅助组和全镜组,每组34例。辅助组患者采用腹腔镜结直肠癌(CRC)根治术联合开腹CRLM切除术治疗,全镜组患者采用全腹腔镜切除术治疗,比较两组患者术中术后指标、术后并发症发生率及生存时间。结果两组患者手术时间和术中出血量比较,差异无统计学意义(P> 0.05)。两组患者术后排便时间和住院时间比较,差异无统计学意义(P>0.05)。辅助组患者并发症发生率为44.1%,全镜组为32.4%,差异无统计学意义(P> 0.05)。两组患者无病生存时间和总生存时间比较,差异无统计学意义(P> 0.05)。结论全腹腔镜与腹腔镜辅助同期切除术治疗CRLM患者的安全性及有效性结果接近,临床可根据患者病情合理选择手术方式。     

Is laparoscopic liver resection safe for intrahepatic cholangiocarcinoma? A meta-analysis

BackgroundThe use of laparoscopic liver resection for curative surgery of intrahepatic cholangiocarcinoma (ICC) is not well established. Herein, we perform a meta-analysis to compare the differences between laparoscopic liver resection (LLR) and open liver resection (OLR) for ICC.MethodsMultiple electronic databases were searched and 8 relevant studies containing 552 patients treated by LLR and 2320 treated by OLR were identified. The fixed effects and a random-effects model were used to perform a meta-analysis.ResultsCompared with OLR, LLR for ICC was associated with less blood transfusion (7.14% versus 17.11%; OR: 0.32; 95% CI 0.15 to 0.71; P < 0.05), higher R0 resection (85.63% versus 74.69%; OR: 1.48; 95% CI 1.13 to 1.95; P < 0.05), shorter length of stay (LOS) (SMD: −0.40; 95% CI -0.80 to 0.00; P = 0.05), less overall morbidities (20% versus 32.69%; OR: 0.50; 95% CI 0.33 to 0.78; P < 0.05), and less death due to tumor recurrence (22.39% versus 35.48%; OR: 0.50; 95% CI 0.29 to 0.86; P <0.05); but LLR was associated with smaller ICC, fewer major hepatectomies, less lymph node (LN) dissection rate, and inferior 5-year overall survival (OS) (P < 0.05). Duration of operation, blood loss, average LN retrieved, LN metastasis, major morbidities, mortality, tumor recurrence, 3-year OS and disease free survival (DFS), and 5-year DFS were comparable (P >0.05).ConclusionLLR for ICC is in the initial phase of exploration. More evidence is necessary to validate LLR for ICC.     

Percutaneous radiofrequency ablation versus open surgical resection for spinal osteoid osteoma

BACKGROUND CONTEXT

Both open surgical resection (OSR) and radiofrequency ablation (RFA) have been reported for spinal osteoid osteoma (OO).

Robotic left-sided colorectal resection with natural orifice IntraCorporeal anastomosis with extraction of specimen: The NICE procedure. A pilot study of consecutive cases

Background

Despite numerous benefits, only a small fraction of laparoscopic left-sided colectomy is accomplished without the need for an abdominal incision to retrieve the specimen and prepare for anastomosis. We report our early experience with a robotic approach using Natural orifice IntraCorporeal anastomosis with Extraction of specimen (NICE) to help overcome the technical limitations and challenges of this approach.

改良Miccoli腔镜辅助下手术和经乳晕入路单孔法内镜下治疗甲状腺良性肿瘤效果观察

目的探讨改良Miccoli腔镜辅助下手术和经乳晕入路单孔法内镜下治疗甲状腺良性肿瘤的效果。方法对2015年8月～2017年3月我院60例甲状腺良性肿瘤患者进行筛选,依据患者意愿及要求选择手术治疗方式,对改良Miccoli组(30例)与经乳晕单孔组(30例)围术期机体创伤指标、手术指标、术后切口美容效果、术后疼痛指标等展开对比。结果两组创伤相关指标在术前均无差异(P0.05),术后WBC、TSH测验水平均上升,血钙、PTH测验水平下降,且改良Miccoli组波动幅度相较经乳晕单孔组更为轻微,差异有统计学意义(P0.05)。改良Miccoli组手术切口大小、术中出血量、术后引流总量、手术时间、住院时间指标统计均较经乳晕单孔组显著下降(P0.05),住院费用远高于经乳晕单孔组(P0.05)。改良Miccoli组患者颈部活动恢复时间相较经乳晕单孔组明显缩短,术后6 h、12 h及24 h疼痛值低于经乳晕单孔组(P0.05)。对术后1周、1个月及1年切口的美容效果比较,改良Miccoli组均较经乳晕单孔组评分高(P0.05)。改良Miccoli组并发症总发生率(10%)低于经乳晕单孔组(20%),差异有统计学意义(P0.05);总满意度(93.33%)高于经乳晕单孔组(86.67%),但差异无统计学意义(P0.05)。结论对甲状腺良性肿瘤患者予以改良Miccoli腔镜辅助手术及经乳晕入路单孔法内镜治疗,均可取得满意效果,但相对而言,前者对患者机体所造成的创伤应激更小,但费用更高,且后者手术切口位于隐秘部位,颈部无创,故临床在选择术式可充分考虑患者意愿,取更适宜术式。     

Lingual lymph nodes: Anatomy,clinical considerations,and oncological significance

Lingual lymph nodes are an inconstant group of in-transit nodes, which are located on the route of lymph drainage from the tongue mucosa to the regional nodes in neck levels I and II. There is growing academic data on the metastatic spread of oral cancer, particularly regarding the spreading of oral tongue squamous cell carcinoma to lingual nodes. These nodes are not currently included in diagnostic and treatment protocols for oral tongue cancer. Combined information on surgical anatomy, clinical observations, means of detection, and prognostic value is presented. Anatomically obtained incidence of lingual nodes ranges from 8.6% to 30.2%. Incidence of lingual lymph node metastasis ranges from 1.3% to 17.1%. It is clear that lymph nodes that bear intervening tissues from the floor of the mouth should be removed to improve loco-regional control. Extended resection volume, which is required for the surgical treatment of lingual node metastasis, cannot be implied to every tongue cancer patient. As these lesions significantly influence prognosis, special efforts of their detection must be made. Reasonably, every tongue cancer patient must be investigated for the existence of lingual lymph node metastasis. Lymphographic tracing methods, which are currently implied for sentinel lymph node biopsies, may improve the detection of lingual lymph nodes.     

Robotic resection of recurrent pediatric lipoblastoma

This case demonstrates successful resection of a rare, recurrent presacral‐pelvic lipoblastoma in a 19‐year‐old female patient. Because of the anatomical location of the mass and its proximity to vital structures, the robotic approach allowed for both optimal visualization and effective debulking of the mass. Furthermore, with the use of an articulating laparoscopic camera, key visualization of the posterior lateral pelvis was possible. Using a wide breadth of technologies and resources is essential to broadening the surgical armamentarium and achieving resectability in otherwise challenging cases.     

Differences in surgical resection rate and risk of malignancy in thyroid cytopathology practice between Western and Asian countries: A systematic review and meta-analysis

There is increasing evidence showing that clinicians employ different management strategies in their use of The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC). In this meta-analysis, we investigated the differences in diagnosis frequency, resection rate (RR), and risk of malignancy (ROM) between Western (ie, American and European) and Asian cytopathology practices. We searched PubMed and Web of Science from January 2010 to January 2019. Proportion and 95% CIs were calculated using a random-effect model. We used independent sample t tests to compare frequencies, RR, and ROM between Western and Asian practices. We analyzed a total of 38 studies with 145,066 fine-needle aspirations. Compared with Asian practice, Western series had a significantly lower ROM in most of TBSRTC categories, whereas the RR was not statistically different. Focusing on indeterminate nodules, the RR in Western series was significantly higher (51.3% vs 37.6%; P = .048), whereas the ROM was significantly lower (25.4% vs 41.9%; P = .002) compared with those in Asian series. The addition of Asian cohorts increased ROM for most of diagnostic categories compared with the original TBSRTC. In conclusion, this study demonstrates a difference in Western and Asian thyroid cytology practice, especially regarding the indeterminate categories. Lower RR and higher ROM suggest that Asian clinicians adopt a more conservative approach, whereas immediate diagnostic surgery is favored in Western practice for indeterminate nodules. The addition of Asian series into a meta-analysis of TBSRTC altered ROM for several categories, which should be considered in future revisions of TBSRTC.
