Faiz O, Warusavitarne J, Bottle A, et al., 2009, Laparoscopically assisted vs. open elective colonic and rectal resection: a comparison of outcomes in English National Health Service Trusts between 1996 and 2006, Diseases of the colon and rectum, Vol: 52, Pages: 1695-1704, ISSN: 1530-0358
PURPOSE: This study was designed to compare outcomes after elective laparoscopic and conventional colorectal surgery over a ten-year period using data from the English National Health Service Hospital Episode Statistics database. METHODS: All elective colonic and rectal resections carried out in English Trusts between 1996 and 2006 were included. Univariate and multivariate analyses were used to compare 30 and 365-day mortality rates, 28-day readmission rates, and length of stay between laparoscopic and open surgery. RESULTS: Between the study dates 3,709 of 192,620 (1.9%) elective colonic and rectal resections were classified as laparoscopically assisted procedures. The 30-day and 365-day mortality rates were lower after laparoscopic resection than after open surgery (P < 0.05). After correction for age, gender, diagnosis, operation type, comorbidity, and social deprivation, laparoscopic surgery was a strong determinant of reduced 30-day (odds ratio, 0.57; 95% confidence interval, 0.44-0.74; P < 0.001) and one-year (odds ratio, 0.53; 95% confidence interval, 0.42-0.67; P < 0.001) mortality. Similarly, multivariate analysis confirmed that laparoscopic surgery was independently associated with reduced hospital stay (P < 0.001). Patients who received rectal procedures for malignancy, however, were more likely to be readmitted if laparoscopy rather than by a traditional method was used (11.9% vs. 9.1%, P = 0.003). CONCLUSION: In the present study, patients selected for laparoscopic colorectal surgery were associated with reduced postoperative mortality when compared with those undergoing the conventional technique. This finding merits further investigation.

This paper introduces a stereoscopic fibroscope imaging system for Minimally Invasive Surgery (MIS) and examines the feasibility of utilizing images transmitted from the distal fibroscope tip to a proximally mounted CCD camera to recover both camera motion and 3D scene information. Fibre image guides facilitate instrument miniaturization and have the advantage of being more easily integrated with articulated robotic instruments. In this paper, twin 10,000 pixel coherent fibre bundles (590 mu m diameter) have been integrated into a bespoke laparoscopic imaging instrument. Images captured by the system have been used to build a 3D map of the environment and reconstruct the laparoscope's 3D pose and motion using a SLAM algorithm. Detailed phantom validation of the system demonstrates its practical value and potential for flexible MIS instrument integration due to the small footprint and flexible nature of the fibre image guides.

Ballantyne J, Valibeik S, Darzi A, et al., 2008, Robotic navigation in crowded environments: Key challenges for autonomous navigation systems, Pages: 306-312
Crowded environments provide significant challenges for autonomous navigation systems. The robot must be fully aware of its surroundings and incorporate this knowledge into its decision-making and planning processes. The purpose of this paper is to outline major challenges that an autonomous navigation system needs to overcome to enable effective navigation in crowded environments such as hospital wards. We will discuss several key components of autonomous navigation systems to include localization and mapping, human-robot interaction, and dynamic object detection. © 2010 ACM.
