OBJECTIVE Acute cholecystitis is a common disease, and laparoscopic surgery is the standard of care. BACKGROUND Optimal timing of surgery for acute cholecystitis remains controversial: either early surgery shortly after hospital admission or delayed elective surgery after a conservative treatment with antibiotics. METHODS The ACDC ("Acute(More)
Laparoscopic surgery has potential theoretical advantages over open surgery in reducing the rate of adhesion formation, but very few comparative studies are available to prove this. A literature search was performed within Medline and Cochrane databases using the key words: adhesion*, adhesiolysis, laparoscop*, laparotomy, open surgery. Further articles(More)
The aim of the study was to determine if tumor seeding during laparoscopic surgery for cancer is a rare event or a typical complication of this procedure. Laparoscopic staging and treatment of intraabdominal tumors is increasing in gastroenterology, gynecology, and general surgery. A total of 1052 questionnaires were mailed to surgical department chairmen,(More)
Concepts in “fast-track” surgery, which provide optimal perioperative care, have been proven to significantly reduce complication rates and decrease hospital stay. This study explores whether fast-track concepts can also be safely applied and improve the outcomes of major pancreatic resections. Perioperative data from 255 consecutive patients, who underwent(More)
Carbon dioxide, the primary gas used to establish a pneumoperitoneum, causes numerous systemic effects related to cardiovascular function and acid-base balance. Therefore, the use of other gases, such as helium, has been proposed. Furthermore, the pneumoperitoneum itself, with the concomitant elevation of intraabdominal pressure, causes local and systemic(More)
PURPOSE We present an augmented reality (AR) navigation system that conveys virtual organ models generated from transrectal ultrasonography (TRUS) onto a real laparoscopic video during radical prostatectomy. By providing this additional information about the actual anatomy, we can support surgeons in their working decisions. This work reports the system's(More)
We report a method of laparoscopic surgery in the rat. Our technique is illustrated by gastric fundoplication requiring two handed dissection, suturing, and knot tying. This animal model for laparoscopic surgery is relatively inexpensive, can be extended to other operations, and makes use of an extensively studied animal. These factors may facilitate(More)
BACKGROUND Although providing excellent outcome results, laparoscopy also induces particular pathophysiological changes in response to pneumoperitoneum. Knowledge of the pathophysiology of a CO(2) pneumoperitoneum can help minimize complications while profiting from the benefits of laparoscopic surgery without concerns about its safety. METHODS A review(More)
Background: Numerous experimental and clinical investigations indicate that the mononuclear phagocyte system (MPS) has a relevant function in terms of physiological defense against tumor metastasis and bacterial infection. Consequently, a point of major interest is the influence of surgical techniques on the MPS function. Method: The model investigation(More)
Suturing is one of the main tasks in advanced laparoscopic surgery, but limited degrees of freedom, 2D vision, fulcrum and pivoting effect make it difficult to perform. Robotic systems provide corresponding solutions as three-dimensional (3D) view, intuitive motion and additional degrees of freedom. This review evaluates these benefits for their impact on(More)
