Abstract

INTRODUCTION: The most popular scale to stratify the postoperative risk is the Obesity Surgery Mortality Risk Score (OS-MRS). The design and ease of interpretation make the scale a potential tool for clinical use.

AIM: To evaluate the usefulness of the OS-MRS scale in the enrollment of patients for laparoscopic bariatric procedures, including laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB).

MATERIAL AND METHODS: The medical records of patients who underwent LSG or LRYGB due to obesity between January 2010 and December 2010 were reviewed retrospectively. The decision of choosing the surgical procedure was made on the basis of OS-MRS risk category. The primary endpoint of this study was the 90-day mortality, and the secondary endpoint was the presence of major complications.

RESULTS: There were 107 patients including 66 women and 41 men. The OS-MRS classes were A (48%), B (47%) and C (5%). The LSG was applied to patients with higher body mass index and to patients of class C. The secondary endpoints occurred in 6 patients, distributed in 10% of class A, 2% of class B and 0% of class C patients (p < 0.05). In 5 of 6 cases the endpoint was observed after LRYGB. Fatal cases were not observed.

CONCLUSIONS: The OS-MRS can be a useful clinical tool for choosing the appropriate laparoscopic bariatric procedure, depending on the risk of postoperative complications. Low risk of postoperative complications should not lower the watchfulness of the surgeon.

Keywords: Obesity Surgery Mortality Risk Score; bariatric surgery; obesity; postoperative complications
