BACKGROUND Laparoscopic suprapubic hernia repair (LSHR) is frequently a technically difficult procedure. This is often due to extensive adhesions from multiple previous operations, the necessary wide pelvic dissection, and adequate mesh coverage with transfascial suture fixation. The aim of the current study was to document the complications and morbidity(More)
The da Vinci® Surgical System (Intuitive Surgical, Sunnyvale, CA, USA) is a computer-assisted (robotic) surgical system designed to enable and enhance minimally invasive surgery. The Food and Drug Administration (FDA) has cleared computer-assisted surgical systems for use by trained physicians in an operating room environment for laparoscopic surgical(More)
Natural orifice translumenal endoscopic surgery (NOTES) is surgically challenging. Current endoscopic tools provide an insufficient platform for visualization and manipulation of the surgical target. This study demonstrates the feasibility of using a miniature in vivo robot to enhance visualization and provide off-axis dexterous manipulation capabilities(More)
OBJECTIVE This study aims to examine trends of utilization and rates of conversion to open procedure for patients undergoing laparoscopic colon resections (LCR). METHODS This study is a national database review of academic medical centers and a retrospective analysis utilizing the University HealthSystem Consortium administrative database-an alliance of(More)
BACKGROUND The prevalence of gastroesophageal reflux disease (GERD) in the morbidly obese population is as high as 45%. The objective of this study was to compare the efficacy of various bariatric procedures in the improvement of GERD. METHODS The Bariatric Outcomes Longitudinal Database is a prospective database of patients who undergo bariatric surgery(More)
Robotic laparoscopic surgery has revolutionized minimally invasive surgery for the treatment of abdominal pathologies. However, current training techniques rely on subjective evaluation. The authors sought to identify objective measures of robotic surgical performance by comparing novices and experts during three training tasks. Five novices (medical(More)
This study demonstrates the feasibility of using a miniature robot to perform complex, single-incision, minimal access surgery. Instrument positioning and lack of triangulation complicate single-incision laparoscopic surgery, and open surgical procedures are highly invasive. Using minimally invasive techniques with miniature robotic platforms potentially(More)
Feasibility and effectiveness of minimally invasive surgery have made the use of robotic surgical system a rising prevalence with a wide range of applications. However, as a remarkable result, how to adroitly and precisely manipulate the sophisticated robotic surgery instruments is of fundamental importance to new surgeons. In order to provide the robotic(More)
The clinical utility of cholecystokinin-cholescintigraphy with calculation of a gallbladder ejection fraction (GBEF) in patients with suspected chronic acalculous gallbladder dysfunction (CAGD) remains controversial. It was our aim to critically evaluate the literature on the utility of the GBEF to predict outcome of patients with suspected CAGD. We(More)
BACKGROUND Controlling surgical task speed and maintaining accuracy are vital components of robotic surgical skills. This study was designed to investigate the relationship between accuracy and speed for robot-assisted surgical skills. METHODS Ten participants were asked to alternately touch two circular targets with various dimensions and distances(More)
