Introduction: The choice of an appropriate surgical procedure for the treatment of obesity is critical to achieving effective and safe outcomes. This study aimed to compare the safety of two popular procedures: Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) in terms of operative time, length of hospitalization, reoperations, and complications according to the Clavien-Dindo scale (C-D).

Methods: A retrospective analysis of clinical data was conducted on patients who underwent bariatric surgery between September 2021 and April 2023 at our institution. Patients who underwent Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) were included in the analysis. Operative time, length of hospitalization, reoperations, and complications classified according to the Clavien-Dindo scale were assessed.

Results: The analysis included 94 patients, of whom 13 underwent RYGB and 81 underwent SG. The mean operative time was 157.46 minutes (SD 28.56) for RYGB and 83.48 minutes (SD 17.83) for SG. This difference was statistically significant (p < 0.05). Hospitalization length was 3.6 (SD 0.6) days for RYGB and 3.3 (SD 0.6) days for SG. No reoperations were required in the RYGB group, whereas 2.47% of SG patients required reoperation. In the RYGB group, 7.7% of patients had Class I complications according to the Clavien-Dindo scale. In the SG group, 4.9% had Class I and 2.5% had Class IIIB complications.

Conclusions: This retrospective study suggests that both Roux-en-Y gastric bypass and sleeve gastrectomy are safe surgical procedures for the treatment of obesity. Apart from the significantly longer operative time associated with Roux-en-Y gastric bypass, no statistically significant differences were observed between the procedures in terms of length of hospitalization, reoperations, and complications according to the Clavien-Dindo scale. Our results can contribute to informed decision-making regarding the choice of a surgical procedure for obesity treatment, with particular consideration of patient safety.
