There is a complete paucity of literature for left-handed surgeons. Some studies revealed that left-handed surgical residents have lesser operating skills and some surgeons have considered leaving surgery at some point in their career owing to laterality-related frustrations. Most important, whereas minimally invasive surgical techniques have had a profound impact on the treatment of diseased gallbladder, these procedures do not eliminate laterality related to the discomfort of left-handed surgeons. Usually, left-handed surgeons must teach themselves a procedure. They must make modifications and learn some technical tips to make a more comfortable, convenient, and safe intervention. The aim of this study was to describe some modifications made by a left-handed surgeon to perform 52 safe laparoscopic cholecystectomies with standard right-handed instruments in our hospital. These surgical steps could be used in a reproducible way to minimize the recurring difficulties of left-handed learners in a surgical residency program.
Conference Paper: Real-time interference ing method T1A.3 for mobile communication systems[Show abstract] [Hide abstract]
ABSTRACT: Deployment of next-generation wireless networks requires systems capable of operating in high-mobility environments. High performances are necessary for the antenna system and in particular the capability to reconfigure the radiated beam and adaptively change the shape of the radiation pattern in order to optimize the radiation coverage while minimizing the interferences. In this paper, a novel phase-only adaptive ing method is proposed, which is based on the description of the phase distribution of the array excitation by means of a weighted sum of proper basis functions. By optimizing the weights of this sum, rather than the phase of each element, the problem becomes almost independent of the size of the array, and its convergence speed makes it suitable for realtime applications. The present work shows that with this method both interference ing and signal tracking can be efficiently achieved.Radio and Wireless Conference, 2004 IEEE; 10/2004

ABSTRACT: Laparoscopic cholecystectomy is one of the most frequently performed surgical procedures by the general surgeon. This situation allows determining a defined surgical strategy in most patients. However, some factors may induce modification by the surgical team. Our objectives were to describe and analyze the variation of the surgical technique used during laparoscopic cholecystectomy in a female patient with situs inversus totalis. We report the case of a 70-year-old female with a diagnosis of chronic gallstone cholecystitis and situs inversus totalis. Modifications in the surgical technique are detailed, and anatomic variations of the intraabdominal organs are described. Postoperative evolution was satisfactory and the patient was highly satisfied with the surgical outcome. There was no associated morbidity. Variations in intraabdominal anatomy, alteration of cystic artery location and changes in position of the abdominal ports prompted us to modify the standard surgical technique for laparoscopic cholecystectomy. However, these factors did not alter results or the patient's postoperative evolution.Cirugia y cirujanos 01/2009; 77(2):145-8. · 0.18 Impact Factor
