Laparoscopic Right Colectomy
No full textJacobs et al. first reported a case of laparoscopic right colectomy was in 1991. Since then several reports, large series and randomized controlled trials proved that laparoscopic right colectomy is equal to open surgery in terms of oncological results. Furthermore, minimally invasive approach to right colon has also been proved safe and feasible for benign disease. Recent data also demonstrated that the laparoscopic approach has several advantages in comparison to open techniques including shorter postoperative stay, lesser use of analgesia, shorter postoperative ileus, reduction in wound related complications and incisional hernia rate and faster return to normal life activities
Laparoscopic Transperitoneal Adrenalectomy
No full textFirst described by Gagner et al. and Higashihara et al. in 1992 laparoscopic adrenalectomy is now considered the gold standard treatment for removal of adrenal masses. Reduction in post-operative stay, wound related complications, pain and faster return to normal activities in comparison to standard open technique represent the main benefits of the minimally invasive approach. Current indications for laparoscopic transperitoneal approach to the adrenal glands are removal of benign functioning and non-functioning tumors of the adrenal gland <12-cm
Ergonomics in the operating room: transition from open to image-based surgery
No full textAt several specializations, more often minimal invasive procedures are performed instead of open surgery. Laparoscopy is a minimal invasive technique, which is carried out in the abdominal cavity. In spite of the fact that surgical principles are the same for open and laparoscopic procedures, laparoscopy has changed the way of interaction between the surgical team and the operating field in many ways. These changes however have not led to the required adaptations in the operation room to improve the surgical quality and to optimize the work conditions of the surgical team. In this respect, ergonomics can play a role to fit the work environment to the user and improve the surgical quality accordingly. The aim of this thesis is to improve the surgical quality by applying ergonomics (physical, sensory and cognitive) in the operating room. This thesis discusses different studies. The current situation in the Dutch hospitals concerning ergonomics and the aptitude of the operating rooms for laparoscopy is mapped out. Furthermore, in the field of physical ergonomics a product solution, which reduces the physical complaints and the discomfort that the surgical team experiences during procedures, is proposed and evaluated. Subsequently, the sensorial and cognitive aspects of laparoscopic procedures and in particular the image quality during laparoscopic surgery are assessed. This study consists of objective and subjective measurements in thirty-six Dutch hospitals. At last, the results are translated into solutions and methods, which can be applied both by the designers and by the surgical team.Industrial Design Engineerin

Stress response to laparoscopic surgery: a review
No full textStress response to laparoscopic surgery: a review. Buunen M, Gholghesaei M, Veldkamp R, Meijer DW, Bonjer HJ, Bouvy ND. Department of Surgery, Erasmus Medical Center, P.O. Box 2040, 3000 CA, Rotterdam, The Netherlands. BACKGROUND: Laparoscopic surgery is associated with reduced surgical trauma, and therefore with a less acute phase response, as compared with open surgery. Impairment of the immune system may enhance surgical infections, port-site metastases, and sepsis. The objectives of this review was to assess immunologic consequences of benign laparoscopic surgery and to highlight controversial aspects. METHODS: A literature search on stress response to nonmalignant laparoscopic and open surgery was conducted using the MEDLINE and Cochrane databases. Cross-references from the reference list of major articles on the subject were used, as well as manuscripts published between 1993 and 2002. RESULTS: Local (i.e., peritoneal) immune function is affected by carbon dioxide pneumoperitoneum. The production of tumor necrosis factor and the phagocytotic capacity of peritoneal macrophages are less lowered. The systemic stress response, as determined by delayed-type hypersensitivity response and leukocyte antigen expression on lymphocytes, shows a preservation of immune function after laparoscopic surgery, as compared with conventional surgery. CONCLUSIONS: Intraperitoneal carbon dioxide insufflation attenuates peritoneal immunity, but laparoscopic surgery is associated with a lower systemic stress response than open surger
