单孔加一孔联合ERAS在高位直肠及乙状结肠癌中的应用

目的 探讨单孔加一孔腹腔镜手术联合 ERAS 治疗高位直肠及乙状结肠癌的近期疗效。方法 回顾性分析 2017 年 11 月至2018 年 10 月在福建省肿瘤医院胃肠肿瘤外科进行加速康复外科干预的 92 例高位直肠及乙状结肠癌患者资料，根 据手术方式的不同，分为单孔加一孔手术联合快速康复外科组39 例及常规腹腔镜手术联合ERAS 组 53 例，对比两组围术 期情况。结果 两组患者基线资料无明显统计学差异（P ＞ 0.05），且在手术时间、出血量、上下切缘、清扫淋巴结数量及 并发症方面无明显统计学差异（P ＞ 0.05）。但单孔加一孔手术联合ERAS 组较常规手术联合ERAS 组，总切口长度更短 [（6.7±1.1）cm 比（8.5±1.3）cm，P=0.000]，术后首次下床时间更早 [（22.2±5.2）h 比（27.1±7.9）h，P=0.001]，首次排便 时间更早[（70.2±19.8）h比（83.1±20.4）h，P=0.005]，术后第一天C反应蛋白值更低[（43.5±28.6）mg/L比（57.2±33.2） mg/L，P=0.038]，术后住院时间更短 [（7.0±1.7）d 比（8.1±2.1）d，P=0.010]，且术后 2~4 天疼痛评分更低（P ＜ 0.05）。 结论 经验丰富的腔镜医师采用单孔加一孔手术治疗高位直肠及乙状结肠癌并联合 ERAS 干预是安全可行的，且单孔加一孔 手术可减低操作难度，具有疼痛轻、术后恢复快等优势，值得临床推广。     

原发性骶尾部脊索瘤的CT分型及征象

目的对治疗前原发性骶尾部脊索瘤(PSC)CT图像分型,并分析其CT征象,为诊断和个性化治疗提供依据。方法回顾性分析101例PSC患者治疗前的CT图像,包括肿瘤的部位、范围、大小、密度、肿瘤与邻近结构的关系。按照肿瘤的部位由上及下分为Ⅰ~Ⅳ型,并根据肿瘤侵犯的范围从小到大分为a^d亚型。采用Kruskal-Wallis H检验比较PSC各亚型的占比,并对各亚型之间进行两两比较。采用R×C列联表精确概率检验比较分型和亚型肿瘤钙化的发生率。采用单因素方差分析及LSD-t检验对各分型和亚型肿瘤的大小和密度进行分析、比较。结果101例PSC中,Ⅰ~Ⅳ型的发生率分别为17.8%、30.7%、36.6%、14.9%,a^d亚型的占比分别为9.9%、25.7%、58.4%、5.9%。各亚型的占比差异具有统计学意义(P=0.012)。c亚型明显高于a亚型(P=0.039),d亚型明显低于a亚型(P=0.036),其余各型之间无明显差异。各分型肿瘤内钙化的差异无统计学意义(P=0.233);各亚型肿瘤内钙化的差异有统计学意义(P=0.003),a^d亚型肿瘤钙化的比率逐渐增加。Ⅰ型肿瘤的左右径及上下径明显大于Ⅱ~Ⅳ型(P<0.05)。a亚型与b亚型肿瘤之间前后径的差异无统计学意义(P=0.102),b^d亚型之间前后径的差异均有统计学意义(P<0.05);不同亚型肿瘤之间的左右径、上下径之间的差异均有统计学意义(P<0.05),a亚型径线最小,d亚型径线最大。结论101例PSC中,Ⅱ、Ⅲ型最多见,肿瘤较少累及第一骶骨;各亚型中,a型较少见,c亚型最多见,d亚型最少见。肿瘤的密度与分型无关,肿瘤内钙化与亚型有关。Ⅰ型肿瘤侵犯的范围较Ⅱ~Ⅳ型广泛,a^d亚型肿瘤的径线逐渐增大,CT分型有利于判断肿瘤的范围。PSC诊断延迟现象比较明显,但很少发生远处侵犯和转移。CT图像可对治疗前PSC分型,为诊断和个性化治疗提供依据。

A case of purulent pneumococcal pericarditis

Background

Purulent bacterial pericarditis is a rare and potentially fatal disease. The course may be fulminant, and the presentation may pose a diagnostic challenge.

比较手术夹闭和介入栓塞治疗颅内未破裂动脉瘤安全性和有效性的Meta分析

目的比较手术夹闭和介入栓塞治疗颅内未破裂动脉瘤的安全性和有效性。方法计算机检索1990至2018年颅内未破裂动脉瘤的所有临床对照研究。两名研究员分别纳入研究、提取数据、质量评价并应用Rev Man5. 0软件进行数据处理。结果最终纳入21篇文献,病例数109114例。Meta分析结果提示:手术夹闭组动脉瘤闭塞率为88. 2%,平均住院时间7. 7天,均高于介入栓塞组的65. 3%和4. 1天,P 0. 05。介入组患者的短期死亡率和致残率分别为0. 61%和2. 1%,均低于手术组的1. 27%和4. 7%,P 0. 05。介入组患者的1年期死亡率和致残率(2. 5%、2. 5%)均与手术组(2. 2%、1. 8%)无明显差异,P 0. 05。漏斗图未发现发表偏倚。敏感性分析结果一致。结论介入栓塞相比于手术夹闭可缩短患者的住院时间,降低患者的短期不良预后发生率。但是动脉瘤的闭塞率较低,1年期预后与手术夹闭无明显差异。据此推测手术夹闭患者的长期预后可能要好于介入栓塞,手术夹闭更适合于年轻患者。     

Opioid maintenance treatment: trajectories in and out of treatment

Problem: Although efficacy studies of opioid maintenance treatment (OMT) have shown evidence of treatment benefits, there is still need for studies on its effectiveness in natural clinical processes. This study investigates the development in health, substance use and social conditions of those who applied for OMT, including those denied access or discharged.

Method: First, persons assessed for admittance in 2005–2011 (n?=?127) were categorized into four trajectory groups based on whether they were admitted or denied (n?=?19), discharged (n?=?31), readmitted (n?=?21) or had been undergoing OMT without interruption (n?=?56). Second, 99 of these, the analytical sample, were interviewed at follow-up using (a) the Addiction Severity Index (ASI) for seven problem-areas and housing, and (b) self-rated change in 11 problem areas. The ASI was compared to baseline interviews after 55 months (mean). Third, outcomes within groups was studied in relation to alternative interventions.

Results: Within the analytical sample, those denied OMT showed no improvements at group level, those discharged had some improvements, more if readmitted than if not and those with uninterrupted OMT showed the most comprehensive improvements. Those outside OMT, denied and discharged, had considerable mortality risks related to ongoing drug use, especially in lack of well-planned alternative interventions.

Conclusion: Improvements strongly relate to access to OMT. This study underscores that access to OMT improves the situation in all areas investigated and decreases the risk for drug-related death. It underscores the importance of two major risk situations, i.e. being denied OMT and being discharged.
