[Standardising sigmoidectomy by single umbilical incision]

The increase in single-incision endoscopic surgery has led to more and more procedures and surgical groups who perform them. Segmental resection is the procedure most likely to benefit from this approach since it achieves a significant minimisation in the parietal access; with umbilical mini-laparotomy the entrance ports are grouped together and extraction of the piece and preparation of the anastomosis can be performed. Among the colorectal procedures, sigmoidectomy seems to be the most appropriate area to start using these techniques by groups with laparoscopic colorectal experience. Our aim is the standardisation of single-incision sigmoidectomy, analysing the process with the support of video sequences, and placing emphasis on the factors where it differs from conventional laparoscopy and on the key points in order to avoid problems during the execution of the process.
