Shortening the operative time of laparoscopic colon and rectosigmoid cancer surgery: A comparison of multi-port surgery and single-port surgery using video analysis
Jo Tashiro, Shigeki Yamaguchi

【Purpose】Reducing the operative time of laparoscopic colorectal cancer surgery is desirable. The potential to shorten the operative time of laparoscopic surgery was studied by single-port laparoscopic surgery (SPS) which used less ports and a less assistant surgeon workload than multi-port laparoscopic surgery (MPS).

【Methods】 A total of 106 consecutive colon and rectosigmoid cancer patients, including 53 patients who underwent MPS from October 2012 to December 2013, as well as 53 patients who underwent SPS from SPS induction until January 2014, were selected. The operative time was compared between MPS and SPS. In addition, a video review was performed as part of procedure.

【Results】The major factors to shorten operative time were fewer trocar insertions, solo surgery which reduced the assistant surgeon’s work time, prior umbilical laparotomy, and omission of temporary abdominal wall closure. It was estimated that the operative time of SPS was shorter than that of MPS by more than 10 min.

【Conclusions】The possibility to shorten operative time of laparoscopic colorectal surgery has great potential. Several factors highlighted by video analysis contributed to shortening operative time. Shortened laparoscopic surgery times were enabled by reviewing procedures following SPS for colon cancer and RS cancer, including advanced cancer. Video analysis highlighted the factors contributing to a shortened operative time. These results have positive implications for both patients and gastroenterological surgeons.
