RESUMO
BACKGROUND: Laparoscopy has enjoyed improvements over the last three decades primarily in achieving high definition, but the 70° field of view (FOV) remains unchanged. Complications related to events that take place out of the FOV continue to be reported. Additional problems leading to poor visualization are fogging and smoke accumulation. A novel laparoscopic system (SurroundScope, 270Surgical) was developed and dramatically expands the FOV from the 70° to 270° by adding side cameras at the distal tip of the laparoscope, while LED illumination eliminates fogging and improves smoke effects. This study describes the initial clinical experience with SurroundScope and its potential advantages over traditional laparoscopy. METHODS: SurroundScope was studied at Bnai Zion Medical Center in Israel and the Minnesota Institute for Minimally Invasive Surgery in America. 27 laparoscopic surgeries were performed, and at the end of each procedure, evaluations were completed by all surgeons and camera holders. RESULTS: All 27 cases were completed successfully without adverse events. No injuries occurred as a result of surgical tool manipulation outside of the central frame while 133 potentially adverse events were identified on side frames. There was no fogging across the 27 cases. The impact of smoke was negligible in all cases, as laparoscope removal or venting was never necessary. Surgeon respondents indicated that tools could be followed from the port to the site of surgery without camera manipulation. Most surgeons strongly agreed that the potential to identify bleeding was improved. Camera holders strongly agreed that the ergonomics were improved and that they moved the camera less than with a standard laparoscope. CONCLUSIONS: Initial results demonstrate numerous advantages for SurroundScope as compared to traditional laparoscopy. The important benefits of expanded FOV, complete lack of fogging, and negligible smoke may improve patient safety, reduce adverse events and the duration of surgery. Further investigation to quantify these benefits is recommended.
