Laparoscopic gastric bypass with a single anastomosis resulted in micronutrient deficiency in 46.60% of patients 1 to 3 years after surgery.

Does laparoscopic gastric bypass with a single anastomosis lead to micronutrient deficiency in patients with morbid obesity?
Laparoscopic gastric bypass with a single anastomosis is associated with a high rate of micronutrient deficiencies 1-3 years post-surgery, necessitating careful monitoring especially in high-risk groups.
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.
Strizheletsky et al. (Fri,) conducted a observational in morbid obesity (n=103). Laparoscopic gastric bypass with a single anastomosis was evaluated on micronutrient deficiency. Laparoscopic gastric bypass with a single anastomosis resulted in micronutrient deficiency in 46.60% of patients 1 to 3 years after surgery.
