Abstract

Purpose

SASI (single anastomosis sleeve ileal) bypass can lead to nutritional deficiencies, including disorders of iron metabolism and anemia. This study aims to evaluate the effect of SASI bypass on weight loss, anemia, and iron deficiency in patients with obesity during the follow-up period.

Methods

This study is a retrospective analysis of prospectively collected data from patients who underwent SASI bypass at our hospital between January 2020 and February 2022.

Results

The mean age of the patients was 42 years (range 22–58). The average duration of the follow-up period was 26 months. The mean percentage of excess weight loss (%EWL) was 90.1%, and total weight loss (%TWL) was 30.5%. During the postoperative observation period, anemia was identified in ten patients (25%), comprising 70% with normocytic anemia, 10% with microcytic anemia, and two macrocytic anemia cases (20%). Iron deficiency was observed in two patients (5%).

Conclusion

SASI bypass is an effective bariatric procedure in weight loss outcomes. However, there may be an increased risk of anemia and iron metabolism disruptions associated with this procedure. The common limb length (250 vs. 300 cm) did not significantly impact hemoglobin, iron, TIBC, ferritin levels, or anemia incidence among patients undergoing SASI bypass. The decrease in postoperative ferritin levels signifies a depletion in tissue iron reserves, thereby emphasizing the necessity for surveillance of iron homeostasis parameters following SASI bypass.

Bariatric Surgery Survey 2018: Similarities and Disparities Among the 5 IFSO Chapters

Luigi Angrisani, Antonella Santonicola, Paola Iovino … (2021)

Background The 2018 IFSO Survey focused on similarities and disparities in the number and types of surgical and endoluminal interventions among the IFSO chapters occurred in the last decade. Methods All IFSO Societies were asked to fill in the IFSO survey form on how many and which surgical and endoluminal interventions have been performed in the 2018. A special section was added, asking about the existence of national guidelines for bariatric and metabolic surgery, national recommendations for preoperative gastroscopy, type of reimbursement for bariatric/metabolic surgery, including for patients with BMI < 35 kg/m2. The trend analyses from 2008 to 2018 were also performed. Results Fifty-seven/65 (87.7%) IFSO Societies submitted completed forms. The American Society for Metabolic and Bariatric Surgery did not fill the IFSO survey form but provided an official report on the performed interventions. The total number of surgical and endoluminal procedures performed in 2018 in the world was 696,191. Sleeve gastrectomy (SG) remained the most commonly performed bariatric procedure (N = 386,096; 55.4%). Among the total reported bariatric/metabolic interventions, 604,223 (86.8%) were primary surgical and 29,167 (4.2%) primary endoluminal operations; 62,801 (9%) were revisional procedures. Conclusions There was only a slight increase (10.317 procedures) in the total number of the reported bariatric interventions compared to the last IFSO survey. SG continues to be the most commonly performed operation since 2014. The one anastomosis gastric bypass (OAGB), currently the third most performed procedure after SG and Roux-en-Y gastric bypass (RYGB), continues to rise in popularity worldwide.

American Society for Metabolic and Bariatric Surgery Integrated Health Nutritional Guidelines for the Surgical Weight Loss Patient 2016 Update: Micronutrients.

Julie Parrott, Laura B. Frank, Rebecca Rabena … (2017)

Optimizing postoperative patient outcomes and nutritional status begins preoperatively. Patients should be educated before and after weight loss surgery (WLS) on the expected nutrient deficiencies associated with alterations in physiology. Although surgery can exacerbate preexisting nutrient deficiencies, preoperative screening for vitamin deficiencies has not been the norm in the majority of WLS practices. Screening is important because it is common for patients who present for WLS to have at least 1 vitamin or mineral deficiency preoperatively.

Iron deficiency after bariatric surgery: what is the real problem?

Nele Steenackers, Bart Van der Schueren, Ann Mertens … (2018)

The growing prevalence of obesity explains the rising interest in bariatric surgery. Compared with non-surgical treatment options, bariatric surgery results in greater and sustained improvements in weight loss, obesity associated complications, all-cause mortality and quality of life. These encouraging metabolic and weight effects come with a downside, namely the risk of nutritional deficiencies. Particularly striking is the risk to develop iron deficiency. Postoperatively, the prevalence of iron deficiency varies between 18 and 53 % after Roux-en-Y gastric bypass and between 1 and 54 % after sleeve gastrectomy. Therefore, preventive strategies and effective treatment options for iron deficiency are crucial to successfully manage the iron status of patients after bariatric surgery. With this review, we discuss the risks and the contributing factors of developing iron deficiency after bariatric surgery. Furthermore, we highlight the discrepancy in the diagnosis of iron deficiency, iron deficiency anaemia and anaemia and highlight the evidence supporting the current nutritional recommendations in the field of bariatric research. In conclusion, we advocate for more nutrition-related research in patient populations in order to provide strong evidence-based guidelines after bariatric surgery.
