Patients who received an LRYGB at our institution in 2020 or 2022 for a guideline-compliant indication should be included in the study.
All patients from 2020 had not received an L-TAP block, whereas all patients from 2022 had received such an additional block. Cases without L-TAP in 2022 were excluded.
All other bariatric surgery procedures should be excluded from the survey, e.g. single-anastomosis bypass, reoperations, gastric sleeve resections and combination procedures such as LRYGB with cholecystectomy, partial gastric resection or with placement of a non-adjustable gastric band as an additional procedure in the same surgical session. Furthermore, revision surgery in the event of treatment failure or late complications, conversion to open surgery and persons under the age of 18 were excluded.
