1. A sheathing device for guiding insertion and extraction of a bougie into and from a stomach during a sleeve gastroplasty, the sheathing device comprising a tubular body having a main elongated lumen for slidably receiving the bougie therein, and the tubular body being translatable with respect to the bougie between:
a first position in which the tubular body at least covers a guiding segment of the bougie during insertion and extraction of the guiding segment into and from the stomach, and
a second position in which the tubular body is staggered with respect to the guiding segment for allowing the guiding segment to serve as guide to form a sleeve within the stomach.
