Technical Considerations in Laparoscopic Fundoplication

Gastroesophageal reflux disease (GERD) is a common disease and can be successfully treated by laparoscopic fundoplication. This article describes the technique of laparoscopic surgery for GERD with a focus on operative pitfalls.     

In vivo quantification of fluorescent molecular markers in real-time: A review to evaluate the performance of five existing methods

With the advent of molecular-targeted fluorescent markers, there is a renewed interest in fluorescence quantification methods that are based on continuous wave excitation and multi-spectral image acquisition. However, little is known about their in vivo quantification performance. We reviewed the performance of five selected methods by analytically describing these and varying input parameters of irradiance, excitation geometry, collection efficiency, autofluorescence, melanin content, blood volume, blood oxygenation and tissue scattering using optical properties representing those for human skin. We identified one method that corrects for variations in all parameters. This requires image acquisition before and after marker administration, under identical geometry. Hence, it is suited for applications where the site of interest can be relocated (e.g. anaesthetized animals and dermatology). For applications where relocation is not possible, we identified a second method where the uncertainty in the fluorescence signal was ±20%. Hence, use of these methods can substantially aid in vivo fluorescence quantification compared to use of the raw fluorescence signal, as this changed by more than 3 orders of magnitude. Since these methods can be computed in real-time, they are of particular interest for applications where direct feedback is critical, as diagnostic screening or image-guided surgery.     

Planning for minimally invasive unicompartmental knee arthroplasty

Unicompartmental knee arthroplasty (UKA) is considered the treatment of choice in patients with single compartment arthritis of the knee at early stages or with osteonecrosis limited to one compartment. However, results in the literature are still controversial and it is a technically difficult procedure. The main goal of UKA is to restore the articular space of the afflicted compartment, without influencing the limb alignment. Selection of patients and pre-operative planning are crucial. The necessity to improve functional results and to reduce immobilization of the patients has led to the development of minimally invasive surgery. Applied to UKA, this approach reduces blood loss and surgical time, causes fewer symptomatic postoperative complications, and permits earlier recovery compared to the traditional incision. The shorter incision makes careful pre-operative planning essential. We briefly review the indications for UKA, the pre-operative clinical and radiological assessment, and the surgical procedure.

鼻胃管胃肠减压在择期腹部手术中的应用价值

鼻胃管胃肠减压曾被常规应用于择期和急诊的腹部手术后，目的是预防急性胃扩张的发生、治疗梗阻、降低吻合口压力等。但是，鼻胃管置入也会带来一些副作用，如呼吸道并发症、胃-食道反流、体液和电解质的丢失、声带的损伤，以及越来越被重视的患者的不适感。近年来的研究结果也对择期的腹部手术后常规应用鼻胃管胃肠减压提出不同的看法。现重新评价应用鼻胃管胃肠减压的理论基础及相关临床研究的结果，并对鼻胃管胃肠减压在择期腹部手术中的价值作一综述。     

TSS and traditional surgery in hip and knee replacement

Surgery passes through a continuous evolution, thanks to the introduction of new technologies and techniques. Tissue-sparing surgery is a concept introduced in the last years to address prosthetic surgery to a more conservative fashion. We discuss the TSS decalogue with a critical eye, pointing out how traditional surgery is evolving in accordance with TSS statements.

后腹腔镜下肾肿瘤剜除术的临床疗效观察(附5例报告)

目的：探讨后腹腔镜下肾肿瘤剜除术的操作要点及临床价值。方法：采用后腹腔镜下肾肿瘤剜除术治疗肾肿瘤5例，其中肾癌3例，肾错钩瘤2例，瘤体直径1．5～4．0cm。具体方法是：①暴露瘤体和肾动脉；②采用硅胶管牵拉肾动脉，必要时可暂时阻断肾动脉；③于瘤体1cm正常肾组织处用电钩切除瘤体；④采用生物蛋白胶、止血纱布缝合加压处理创面出血。结果：手术均获成功。手术时间150～210min，术中出血80～350ml。术后1～2天肠道功能恢复并可床上活动，1～4天可下床活动。术后住院5～9天，平均7天。结论：后腹腔镜下肾肿瘤剜除术具有创伤小、康复快、安全、住院时间短等优点；对外生性生长、直径小于4cm瘤体，该法可作为首选手术方法。
