Evaluation of technical feasibility and safety of Single-Site™ robotic right colectomy: three case reports

BACKGROUND

Robotic Single-Site™ surgery overcomes the technical constraints of single-access laparoscopy. After performing over 130 Single-Site robotic cholecystectomies and stabilizing operative times, we applied this technology to right colon surgery.

METHODS

We successfully completed three Single-Site robotic right colectomies (SSRRCs) using the da Vinci Si Surgical System(®) with a Single-Site kit (© Intuitive Surgical™) inserted through a suprapubic incision.

RESULTS

Overall SSRRC operative time was 218.3 ± 75.9 min. A side-to-side anisoperistaltic anastomosis was fashioned intracorporeally (two cases) or extracorporeally (one case). All patients were discharged within 5 days. There were no complications and oncological principles were satisfied. There were no recurrences up to 12 months.

CONCLUSIONS

This is the first report of SSRRC with intracorporeal anastomosis using the da Vinci(®) Single-Site™ port inserted through a suprapubic incision. This approach is feasible and safe, with oncological outcomes potentially equivalent to those of robotic or laparoscopic multiport surgery.

Present and future advanced laparoscopic surgery

Modern laparoscopy, starting with Kurt Semm's insufflators and the first successful appendectomies, has only been around for approximately 30 years. Since those early successes, the technology has grown from the inception of basic laparoscopy to endoscopic surgery through natural orifices, and it continues to evolve by leaps and bounds with computer-assisted surgery and improved robotics in surgery. Without question, laparoscopy has revolutionized the way we perform standard surgery, especially relative to the techniques that had been used for hundreds of years. Despite the development of multiple novel technologies since the 1980s, very little has changed with regard to basic conceptualizations and practice of laparoscopy. In this review article, we will describe the highlights of recent advanced laparoscopic surgery procedures, their potential applications within the field of surgery, and how these advances may impact and improve future quality and patient outcomes.

Comparison of short-term surgical outcomes after single-incision laparoscopic versus multiport laparoscopic right colectomy: a two-center, prospective case-controlled study of 100 patients

BACKGROUND

Recent case studies have demonstrated the feasibility of single-incision laparoscopic colectomy (SILC). Few comparative studies for SILC and multiport laparoscopic colectomy (MLC) have been conducted. The aim of this case-controlled study was to compare the short-term surgical outcomes between SILC and MLC for right-sided colectomies.

METHODS

Between January 2010 and February 2012, data from the first 50 consecutive patients that underwent right SILS at one of the two institutions were compared with a group of 50 consecutive patients that underwent right MLC in the same period.

RESULTS

Median operative time was significantly shorter in SILC (97 vs. 112 min; p < 0.001). Between both groups, no statistically significant differences were found regarding number and nature of short-term complications, number of reoperations [4 (8%) vs. 6 (12%)], and mortality rate [1 (2%) vs. 2 (4%)]. Median postoperative hospital stay was 6 days for both groups.

CONCLUSION

SILC is a safe and feasible procedure when performed by experienced laparoscopic surgeons. Length of hospital stay and overall complication rates are comparable with MLC. Until today, no clear advantages of SILC over MLC have been demonstrated. However, due to its smaller incisional trauma, SILC could be a major step in improving cosmetic outcomes.
