Background: Obesity is associated with a higher incidence of several diseases, including diabetes, cardiovascular disease,
and cancer. Bariatric surgery, regardless of its type, is the most effective approach for treating morbid obesity. This study
aimed to compare the outcome of SASI bypass with that of RYGB regarding weight loss, improvement in comorbidities,
malnutrition, and postoperative complications.
Methods: Patients with morbid obesity who underwent RYGB or SASI bypass and were followed for 12 months from May
2020 through May 2021 were included in the current prospective study. Weight loss, improvement in comorbidities,
complications, and nutritional status were compared between a group of consecutive patients who underwent SASI bypass
and a group of patients who underwent RYGB during the same study period.
Conclusion:The average percentage of postoperative weight loss was not significantly different between the two groups.
There were no significant differences in the remission of comorbidities between the two groups. Few postoperative
complications were reported in both groups. The outcome of SASI bypass and Roux en Yregarding weight loss and
improving of comorbidities were satisfactory
