Correlation of Preoperative Prognostic Laboratory Markers with Bariatric Surgery-Related Complications

Abstract

Introduction: Bariatric surgery is defined as the best long-term treatment for morbid obesity and this leads massive increase in bariatric surgeries worldwide. However, these procedures are associated with severe morbidities and mortalities. And the clarification of preoperative predictors is still unclear today. Materials and Methods: We collected all clinical and laboratory findings of the patients retrospectively who underwent elective bariatric surgery at our hospital (2018–2021). We evaluated the parameters in terms of predictors of early complications. Results: From January 2018 to August 2021, 325 patients underwent bariatric surgery (sleeve: 172–bypass: 153). In total, 24 patients had early postbariatric complications (11 leak, 10 bleeding, and 3 pulmonary embolism). After evaluation of the data, preoperative laboratory markers and ratios were not found to be significantly associated with major complications. Only “asthma” as a comorbidity was a significant predictor of postbariatric surgery complications. Conclusion: The preoperative laboratory markers and ratios are potential prognostic factors for postoperative morbidities and mortalities in patients undergoing bariatric surgery. Our clinical findings do not correlate with major complications. More prospective studies and larger number of patients are needed to shed light on the potential importance of these parameters.
