近年加速康复外科（ERAS）在外科领域得以广泛应用，减重与代谢外科有其特殊性，建立适合中国国情的减重与代谢外科ERAS原则专家共识十分必要。

参照改良Delphi方法建立《减重与代谢外科加速康复外科原则中国专家共识（2021版）》。由20位从事减重与代谢外科的专家组成专家组，提出、审核EARS原则条目，由专家组邀请56位有经验的减重与代谢外科医师，共76位专家对42项ERAS原则条目进行投票，经两轮投票赞成率≥70%的条目为达成共识。

经第一轮投票，42项ERAS原则条目中，14项赞成率<80%；经第二轮投票，最终36项ERAS原则条目达成共识，6项条目未达成共识。

结合文献证据及中国减重与代谢外科具体情况，建立《减重与代谢外科加速康复原则中国专家共识（2021版）》，供减重与代谢外科医师临床实践中参考。

The concept of enhanced recovery after surgery (ERAS) has been widely applied in surgical practice. Bariatric and metabolic surgery has its complexity and particularity. It is necessary to develop the Chinese expert consensus on the ERAS principles in bariatric and metabolic surgery.

The Chinese expert consensus on enhanced recovery after surgery principles in bariatric and metabolic surgery (2021 edition) was built up based on the modified Delphi approach. We created a committee of 20 recognized experts in bariatric and metabolic surgery who were responsible for proposal, review and voting for the statements. The committee invited 56 bariatric and metabolic surgeons to vote on 42 statements concerning on ERAS with the total voters were 76 people. After two rounds of voting, the agreements amongst ≥70.0% were regarded as reaching consensus.

The agreement rate was less than 80% in 14 statements of the 42 statements in the first round voting. At the second round voting, no consensus was achieved in 6 statements. Thirty-six statements were considered achieving consensus.

Based on literature evidence and the specific situation of bariatric and metabolic surgery in China, the Chinese expert consensus on enhanced recovery after surgery principles in bariatric and metabolic surgery (2021 edition) was achieved. This expert consensus can be used as a reference for bariatric and metabolic surgeons in clinical practice.
