ABSTRACT
Background: Obesity is a global epidemic associated with increased mortality and morbidity. Bariatric surgery
has emerged as a successful intervention for clinically morbid obesity, often incorporating pre-operative weight
loss criteria. The relationship between preoperative weight reduction and bariatric surgery outcomes remains
underexplored. This study aims to investigate the effect of pre-operative weight reduction on post-operative
outcomes in a Jordanian population. Methods: A single-center, retrospective, comparative study was conducted at
King Hussein Medical Hospital, Jordan, between March 2019 and March 2020. The study enrolled patients who
underwent bariatric procedures, categorizing them into two groups: those achieving a 10% pre-operative weight
reduction (Group A) and those without weight reduction (Group B). Data collection included demographic,
clinical, and operative variables. Results: Among 280 patients, predominantly female (91%), Group B exhibited a
significantly higher BMI (Mean: 53.0 vs. 39.0, p-value<0.001) and increased post-operative WBC levels (means:
11.5 vs. 10.2, p-value=0.027). Group A demonstrated better outcomes, with 13% post-operative complications in
Group B, including bleeding, hernia, intestinal obstruction, and intra-abdominal abscess. Conclusion: Our study
suggests a potential benefit of pre-operative weight reduction in enhancing post-operative outcomes in bariatric
surgeries among the Jordanian population. The observed differences in BMI, WBC levels, and postoperative
complications between groups emphasize the relevance of pre-operative interventions in optimizing surgical
results.
