Background
A web-based survey was conducted among colorectal surgeons who represented members of both SAGES and ASCRS to find out how they define conversion for laparoscopic colorectal surgery.
Methods
Questionnaires were designed based on MCQs, including three parts: surgeon information, different definitions for conversion, and four different clinical scenarios. Surgeons were asked to choose the best definition(s).
Results
325 (28.5%) of 1,140 surgeons, 28.5% responded; approximately half of them were part of private-based practices. Fifty-three percent had more than 10 years experience; 35.9% performed more than 50 laparoscopic colon cases per year, 12% performed more than 25 laparoscopic rectal cases per year, and 60% less than 10. The majority (68.4%) agreed that any incision made earlier than planned is conversion. Whereas 81.4% felt that incision >5 cm is not a conversion, only 53.4% considered incision >10 cm a conversion, and 37% did not. Neither extracorporeal vessel ligation (73.8%), bowel resection (81.2%), anastomosis (77%), or incision made for specimen retrieval (91.1%) was counted as conversion. In clinical case scenarios, 62% found an incision made to facilitate phlegmon dissection after laparoscopically mobilizing the left colon up to and around the splenic flexure to be laparoscopic-assisted. A 10-cm incision required for fistula take down after finishing laparoscopic dissection was defined as conversion (55.6%). A 10-cm incision made for the rectal dissection in rectopexy was described as conversion in 51% and laparoscopic-assisted in 48%. Increasing a 5–12-cm for specimen extraction, 49.3% was declared a laparoscopic-assisted case.
Conclusions
It was considered clear that any incision made earlier than planned a conversion, whereas extra corporeal vessel ligation, bowel resection and anastomosis were not. However, there seem to be many views of conversion regarding incision length, and some clinical situations that might influence outcome among different centers.
