A number of different access techniques have emerged within reduced port laparoscopy. The multi-trocar approach via separate fascial incisions and multichanneled single trocar devices have challenged reliable paradigms of multiport laparoscopy (MPL). Although benefits of the reduced port technique have yet to be proven, change has begun without comprehensive evaluation. Given that this new platform […]
The emergence and early application of reduced port laparoscopy requires comparison to current accepted safe standards of multiport laparoscopy (MPL). Evaluation of single port access platforms with attention to ease of use and limitations is necessary. These new techniques introduce increased size (5- 20mm) or number (1-4) of fascial defects at a single access point. […]
Introduction: Previous studies have reported less acidemia and decreased intraoperative stress during NOTES procedures using endoscopic air insufflation compared to standard laparoscopy in a porcine model. Insufflation gas (Co2 vs air) and pneumoperitoneal pressure may contribute to these findings. Objectives: 1-To evaluate the effects of CO2 versus intraabdominal pressure on intraoperative acidosis. 2-To compare the […]
Background: Minimally invasive surgery is based on visualization with less reliance on tactile feedback. Therefore, the type of laparoscope, location of the laparoscopic working port, light transmission, viewing angle, depth of view, camera, magnification, image display and clarity are critical. Rigid laparoscopes with fixed viewing angles are the most employed worldwide because of their ease […]
Introduction: To identify pre-operative, intra-operative, and post-operative variables that impact the long term results of laparoscopic Heller myotomy in patients with Achalasia. Methods and Procedures: A retrospective record review and telephone interview with a standardized questionnaire was conducted on 122 consecutive patients who underwent a laparoscopic Heller myotomy from 1995 to 2008. A partial fundoplication […]
