Standardization of the definition of the types of oncological colectomy. Delphi method for consensus of experts of the Spanish Association of Surgeons

Abstract

There is no international consensus on the definition of the type of oncological resection that corresponds to each of the colectomies existing in the current literature. The objective is to define for each colectomy described in the literature: embryological dissection plane, vascular pedicles in which to perform central ligation, the extent of the colectomy and the need for resection of the greater omentum. A consensus of experts is carried out through the Delphi methodology through two rounds from the Coloproctology Section of the Spanish Association of Surgeons. Study period: November 2021-January 2023. 120 experts were surveyed. Degrees of consensus: Very strong: >90%, strong: 80-90%, moderate: 50-80%, non-consensus: < 50%. The definition for each oncological colectomy was established by very strong and strong recommendations. Each oncological colectomy was established by right hemicolectomy (RHC), RHC with D3 lymphadenectomy, extended-RHC, transverse colon segmentary colectomy, splenic flexure segmentary colectomy, subtotal colectomy, total, left hemicolectomy (LHC), extended-LHC, sigmoidectomy.
