Sleeve-forming gastrectomy is the right terminology.

Gastric sleeve is the final result when a vertical or sleeve-forming gastrectomy is performed. There is controversy about the nomination of the procedure to make a lesser curvature gastric sleeve (LCS) since the term sleeve gastrectomy, used commonly, is grammatically a misnomer. Lexicon incorrectness should not be accepted scientifically for any nomination. The Spanish Royal Academy of Medicine and seven leaders of the International Federation for the Surgery of Obesity (IFSO) were consulted. Four past IFSO presidents, four chief editors of the Obesity Surgery journal and two presidents of national associations all agree that the sleeve gastrectomy term is a misnomer and sleeve-forming gastrectomy is proposed as the correct term.
