Lobectomy Is Associated with Better Outcomes than Sublobar Resection in Spread through Air Spaces (STAS)-Positive T1 Lung Adenocarcinoma: A Propensity Score–Matched Analysis

Introduction

Spread through air spaces (STAS) is a form of invasion wherein tumor cells extend beyond the tumor edge within the lung parenchyma. In lung adenocarcinoma (ADC), we investigated the (1) association between STAS and procedure-specific outcomes (sublobar resection and lobectomy), (2) effect of surgical margin-to-tumor diameter ratio in STAS-positive patients, and (3) potential utility of frozen sections (FSs) for detecting STAS intraoperatively.

Cranio-caudal approach to hepatic veins in laparoscopic central bisectionectomy (with Video)

BackgroundLaparoscopic central bisectionectomy (Couinaud's segment IV, V, and VIII) needs exposure of the RHV and MHV on the surface of the remnant and the resecting side, respectively. Avoiding venous injury is mandatory and laparoscopy-specific cranio-caudal approach to hepatic veins might be helpful [1]. We present this procedure in performing laparoscopic central bisectionectomy.PatientA 45-year-old female was admitted to our hospital with a 6 cm HCC in the segment VIII and IV. Her comorbid disease was non-cirrhotic HBV hepatitis (Child-Pugh grade A) and diabetes (untreated).MethodAfter cholecystectomy, G₄ branches were dissected and cut by extra- or intra-hepatic approach. Hilar plate was dissected and the G_ant was encircled and occluded by a vascular clip. Afterwards, exposure of the MHV was started at its root on IVC [2,3] and extended in cranio-caudal direction [1]. After sufficient space was obtained around the G_ant, the G_ant and the MHV were cut. Parenchymal transection between right anterior and right posterior sections was also started form the root of the RHV to its cranio-caudal direction. Liver resection was finished with full exposure of the RHV.ResultsThe operating time was 380 minutes, and the blood loss volume was 30 ml. Postoperative CT image showed exposure of the RHV and umbilical portion of Glissonean branch, and no fluid retention.ConclusionLaparoscopy-specific cranio-caudal approach to hepatic veins may be useful to avoid split injury of venous branches [4], especially if the hepatectomy requires complete exposure of hepatic vein, such as central bisectionectomy.     

腰-硬联合麻醉在经尿道前列腺电切术患者中的应用效果

目的探索腰-硬联合麻醉在经尿道前列腺电切术患者中的应用效果。方法选择120例经尿道前列腺电切术患者为试验对象,采用单双号随机化法将其分为观察组和对照组,各60例。观察组采用腰-硬联合麻醉,对照组采用全身麻醉。比较两组麻醉效果。结果术后12 h,观察组S100β、NE水平均低于对照组(P<0.05)。T₁、T₂时,两组MAP、HR均升高,但观察组低于对照组(P<0.05)。观察组胃肠道反应、呼吸抑制、血压下降发生率均低于对照组(P<0.05)。术后1、3、7 d,观察组MMSE评分高于对照组(P<0.05)。结论对经尿道前列腺电切术患者实施腰-硬联合麻醉,能够减轻对患者认知功能的损伤,提高治疗安全性。     

早期胃癌内镜治疗后追加外科手术病例特点、适应证和术式选择

内镜治疗技术的发展进一步推动了早期胃癌的微创治疗。然而，随之而来的问题是，部分接受内镜治疗的病人会出现非治愈性切除。早期胃癌内镜治疗后非治愈性病人的后续处理原则值得进一步关注。结合欧洲肿瘤内科学会（ESMO）、美国国家综合癌症网络（NCCN）及日本胃癌学会等国际指南及相关临床研究并回顾分析单中心数据后可得出结论，eCura-C的病人具有相对较高的癌残留风险，在与病人充分沟通后可考虑追加手术，但仍有较高的术后病理学无癌残留的风险。术式选择和切除范围可参考早期胃癌相关规定。如何准确预测非治愈性病人的淋巴结转移仍是未来的重点。前哨淋巴结活检及腹腔镜内镜联合手术是未来的发展方向。     

腹腔镜下中间入路与侧方入路右半结肠癌根治术的术中、术后情况比较

目的:探讨腹腔镜下中间入路右半结肠癌根治术的临床疗效及并发症。方法:回顾性分析在2015年6月1日至2018年6月1日期间由中国人民解放军第967医院普外科收治的82例右半结肠癌患者临床资料，45例患者接受腹腔镜中间入路右半结肠癌根治术，为中间入路组，37例患者接受腹腔镜侧方入路右半结肠癌根治术，为侧方入路组；对比两组患者手术时间、术中出血量、清扫淋巴结数量、中转开腹率、术后肠功能恢复时间、术后住院时间及术后并发症等临床指标，评价分析腹腔镜下中间入路右半结肠癌根治术的优越性。结果:中间入路组手术时间、术中出血量、淋巴结清扫数量、中转开腹率与侧方入路组相比差异显著，均有统计学意义（P＜0.05）；但中间入路组在术后肠功能恢复时间、术后住院时间及术后并发症发生情况等方面与侧方入路组相比无统计学差异（P＞0.05）。结论:采用腹腔镜下中间入路右半结肠癌根治术能缩短手术时间、减少术中出血量、减少中转开腹率、增加清扫淋巴结个数，近期治疗效果满意，值得在临床中应用并推广。     

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).

The detection and management of complications following the treatment of liver metastases

While once considered as incurable systemic disease, treatment options for liver metastases have increased over the last 30 years and safety has improved dramatically, such that for a selected group of patients the hope of cure can now be offered with radical treatment, and low morbidity interventions can be offered which prolong survival, even in patients with more widely disseminated disease. Advances have been made in selection and surgical technique for liver resection and several adjuncts to resection now exist in the form of portal vein embolization, thermal ablation and targeted drug or radiotherapy delivery options. A natural consequence of these developments has been the delivery of services within fewer specialist units, with the result that later complications of therapy may present to local hospitals, rather than directly to the specialist centres. This article will describe the current common liver-directed therapies and outline the presentation and management of their complications.
