Abstract:

OBJECTIVE

The aim of the study was to evaluate micronutrient deficiency in patients with morbid obesity after laparoscopic gastric bypass with a single anastomosis.

MATERIAL AND METHODS

Analysis of long-term surgical results of treatment of 103 patients with morbid obesity in the period from January to December 2017 based on blood levels of serum iron, vitamin B12, vitamin D and calcium 1—3 years after surgery.

RESULTS

The study included 103 patients whose surgical treatment was chosen using a non-systemic approach and was mainly determined by the preferences of the operating surgeon and the patient. All patients underwent laparoscopic gastric bypass surgery with a single anastomosis. 1—3 years after surgery, 46.60% (48) of patients were found to have vitamin D deficiency, and 41.74% (43) had serum iron deficiency, 34.95% (36) had vitamin B12 deficiency, and 33% (34) had calcium deficiency. In total, micronutrient deficiency developed in 46.60% (48) of patients. Given the unsatisfactory results obtained, after analyzing the data, we identified risk groups for micronutrient deficiency after laparoscopic gastric bypass surgery with a single anastomosis.

CONCLUSION

After laparoscopic gastric bypass surgery with a single anastomosis, micronutrient deficiency develops, which means that this group of patients requires observation and monitoring. Risk factors for developing micronutrient deficiency include a BMI below 43, age under 22 and over 58, and low patient compliance. When choosing the type of bariatric surgery in patients with morbid obesity, it is necessary to assess the risk of developing micronutrient deficiencies.
