About
Prospective association study to analyse patients' outcome after bariatric surgery.
Outcome comprises postoperative pain, analgesia, postoperative side-effects, long-lasting pain, patients' impairment in daily living.
Full description
Background
Bariatric surgery is a common procedure. Data on patient related outcome beyond loss of body weight are scarce. The question arises which patient is at specific risk for an unfavorable outcome after bariatric surgery.
Objective
The aim of this study is to investigate variables possibly associated with impaired outcome and increased patients' interference after bariatric surgery. Which patients are at risk for clinically meaningful impaired daily living?
Methods
Patients will be enrolled in a prospective observational study. Data will be collected in a registry with documentation of patient, surgery, anesthesia and analgesia related variables including preoperative status and postoperative patient reported outcome with a follow-up period up to 5 years after bariatric surgery.
Patients fill in standardized validated outcome questionnaires at predefined time points. The registry provides the basis for large scale analyses and benchmarks for several parameters.
Variables to be considered are pain scores after surgery, patient reported outcome, pain related interference after surgery (Brief Pain Inventory), quality of life (SF-12), long-term outcome, chronic (neuropathic) postsurgical pain, BMI, psychological questionnaires, surgery and patient related variables, including genetic variants.
