Reluctance in duodenal switch adoption: an international survey among bariatric surgeons.

Background: Duodenal switch (DS) still comprises less than 1% of the overall primary procedures in the United States. Our aim is to explore the reasons behind surgeons' reluctance to DS adoption.

Objectives: To determine perceived reasons for the widespread lack of adoption of the DS.

Setting: Worldwide survey of closed bariatric surgery social media groups.

Methods: A standardized questionnaire was posted on 2 closed social media bariatric groups. DS was used as an umbrella term that includes traditional BPD with duodenal switch, single anastomosis duodeno-ileostomy (SADI) and loop DS. The questionnaire link was accessible to bariatric surgeons only for a period of 1 week.

Results: Survey responses (n = 193) were analyzed. The majority (75%) were fellowship-trained bariatric surgeons, and 58% were practicing in the United States. Although 72.9% believed DS to be a good bariatric procedure, it was not being performed by 64% of the respondents. The main reasons behind DS nonadoption included a perceptible high long-term complication rate (43.5%), lack of training (38.1%), and procedure seldomly demanded by patients (31.5%). For surgeons who perform DS, 16.4% use it as a revisional procedure, mainly following sleeve gastrectomy (40.5%). Finally, 29.5% of surgeons believed that the American Society of Metabolic and Bariatric Surgery endorsement of SADI will encourage them to add DS to their practice. They are mostly planning to do so by visiting other surgeons and getting proctored (42.6%).

Conclusion: This survey will help guide bariatric societies and governing bodies in addressing the issues and concerns preventing surgeons from adopting DS in their practice by elucidating the chief reasons and circumstances behind this occurrence.
