Validation of the Modena bleeding score in endoscopic sinus surgery

IntroductionThe Modena bleeding score is a categorical rating scale that allows the assessment of the surgical field in relation to bleeding during endoscopic surgery. It has recently been presented and validated in the field of endoscopic ear surgery by the present authors. The Modena bleeding score provides five grades for rating the surgical field during endoscopic procedures (from grade 1 ? no bleeding to grade 5 ? bleeding that prevents every surgical procedure except those dedicated to bleeding control).ObjectiveThe aim of this study was to validate the Modena bleeding score in the setting of endoscopic sinus surgery.MethodsFifteen three-minute videos of endoscopic sinus surgery procedures (each containing three bleeding situations) were evaluated by 15 specialists, using the Modena bleeding score. Intra and inter-rater reliability were assessed, and the clinical validity of the Modena bleeding score was calculated using a referent standard.ResultsThe data analysis showed an intra-rater reliability ranging from 0.6336 to 0.861. The inter-rater reliability ranged from 0.676 to 0.844. The clinical validity was α = 0.70; confidence limits: 0.64 ? 0.75, corresponding to substantial agreement.ConclusionThe Modena bleeding score is an effective method to score bleeding during endoscopic sinus surgery. Its application in future research could facilitate the performance and efficacy assessment of surgical techniques, materials or devices aimed to bleeding control during endoscopic sinus surgery.     

International Hand Function Study Following Distal Radial Access: The RATATOUILLE Study

BackgroundDistal radial access (DRA) has been proposed to improve procedure ergonomics and favor radial artery patency. Although promising data, nothing is known on evolving hand function after DRA.ObjectivesThis study sought to comprehensively evaluate hand function in patients undergoing DRA.MethodsReal-world patients undergoing DRA undertook a thorough multimodality assessment of hand function implementing multidomain questionnaires (Disabilities of the Arm, Shoulder and Hand and Levine-Katz), and motor (pinch grip test) and sensory (Semmes-Weinstein monofilaments test) examinations of both hands. All assessments were performed at preprocedural baseline and planned at 1-, 6-, and 12-month follow-up (FU). Adverse clinical and procedural events were documented too.ResultsData of 313 patients (220 men, age 66 ± 10 years) from 9 international centers were analyzed. The Disabilities of the Arm, Shoulder and Hand and the Levine-Katz scores slightly improved from baseline to FU (P = 0.008 and P = 0.029, respectively). Pinch strength mildly improved from baseline to FU (P < 0.001 for both the left and right hands). Similarly, touch pressure threshold appeared to faintly improve in both the left and right hands (P < 0.012 for all the sites). For both motor and sensory function tests, comparable findings were found for the DRA hand and the contralateral one, with no significant differences between them. Repeated assessment of all tests over all FU time points similarly showed lack of worsening hand function. Access-related adverse events included 19 harmless bleedings and 3 forearm radial artery and 3 distal radial artery occlusions. None affected hand function at FU.ConclusionsIn a systematic multidimensional assessment, DRA was not associated with hand function impairment. Moreover, DRA emerges as a safe alternative vascular access.     

云南白药对全髋关节置换术出血量的影响

目的研究云南白药在围术期对全髋关节置换术术中出血量及术后引流量的影响。方法2006至2008年我科收治的股骨颈骨折行全髋关节置换术60例,随机分成两组,分别服用云南白药胶囊和空胶囊;术前术后测定凝血酶原时间(PT),记录全部病人术中出血量及术后24 h引流量。结果实验组和对照组病人的凝血酶原时间(PT)差异有统计学意义(P<0.01);试验组的术中出血量、术后24 h引流量分别为(380±78)ml(、336±77)ml,较对照组(481±77)ml(、418±68)ml明显减少,差异具有统计学意义(P<0.01)。结论云南白药胶囊能够明显减少全髋关节置换术围术期出血量。     

不明原因下消化道出血的血管造影及导管治疗

目的：明确下消化道出血原因及止血治疗。材料与方法：对21例不明原因下消化造出血病人行选择性血管造影，并经导管灌注垂体后叶素、明胶海绵条栓塞。结果：血管造影诊断阳性率为76％，16例病人治疗后均止血。结论：血管造影是诊断不明原因下消化道出血的首选方法，垂体后叶素灌注短期（1周）止血效果显著，但易复发，栓塞治疗更重要的在于确定病变部位以利手术。

胆石症合并肝硬化门静脉高压症术中和术后出血的处理

目的总结胆道结石合并门静脉高压症的术中及术后出血的处理经验。方法对2000年1月至2005年7月收治的45例胆道结石合并门静脉高压症并手术的病人进行回顾性分析。结果本组45例病人，治愈38例，死亡7例，病死率为15．6％。发生肝肾功能衰竭，MODS5例，胆囊床大出血2例。死亡病例与肝功能分级有明显关系，肝功能A级死亡1例（5．6％），B级死亡3例（16．7％），C级死亡3例（33．3％）。术后出血9例（20％），包括腹腔内出血6例，消化道出血3例。术后出血病人中6例死亡（66．7％）。结论对合并有门静脉高压症的胆石症病人，加强围手术期处理，可降低死亡率。急诊手术先处理胆道疾病，Child A级病人行腹腔镜手术是安全的。合并有门静脉高压症的胆道疾病者，先行断流加分流手术，再行胆道手术，是最安全的方法。     

Bleeding from gastric ulcer halted by laparoscopic suture ligation

In a 48-year-old Japanese man there was an uncontrollable and recurrent bleeding from a gastric ulcer and laparoscopic surgery was done. Two cannulae were placed in the gastric cavity through the abdominal wall and suture ligation of the bleeding vessel at the posterior wall of the stomach was done under videovisual control with endoscopic guidance. The bleeding ceased, complications were nil, and he remains well.This article reports on surgery done to repair uncontrollable, recurrent bleeding from a gastric ulcer. Two cannulae were placed in the gastric cavity through the abdominal wall and suture of the vessel at the posterior wall of the stomach was done with videovisual control and endoscopic guidance. This approach is concluded to have supplied minimal-access surgery, cost effectiveness, early discharge, less pain, and doctor-patient satisfaction.
