“…In this paper we have focused on the most common performed surgeries, the SG and RYGB. The One Anastomosis Gastric Bypass (OAGB) is a procedure that is gaining popularity, and is the most performed type of surgery in some parts of the world 142 . For the OAGB the stomach is dissected to create a long narrow gastric pouch; a loop of the small bowel is connected at the end of this pouch 143 .…”

Bariatric or weight-loss surgery is a popular option for weight reduction. Depending on the surgical procedure, gastric changes like decreased transit time and volume and increased pH, decreased absorption surface in the small intestine, decreased exposure to bile acids and enterohepatic circulation, and decreased gastrointestinal transit time may be expected. In the years after bariatric surgery, patients will also substantially lose weight. As a result of these changes, the absorption, distribution, metabolism, and/or elimination of drugs may be altered.The purpose of this article is to report the general influence of bariatric surgery on oral drug absorption, and to provide guidance for dosing of commonly used drugs in this special population. Upon oral drug administration, the time to maximum concentration is often earlier and this concentration may be higher with less consistent effects on trough concentrations and exposure. Additionally, prescription of liquid formulations to bariatric patients is supported by some reports, even though the high sugar load of these suspensions may be of concern. Studies on extended release medications result in an unaltered exposure for a substantial number of drugs. Also, studies evaluating the influence of timing after surgery show dynamic absorption profiles. Although for this group a specific advice can be proposed for many drugs, we conclude that there is insufficient evidence for general advices for oral drug therapy after bariatric surgery implying that a risk assessment on a case-by-case basis is required for each drug.

“…On the other hand, bariatric surgery induces 15% to 25% of total weight loss during a 20‐year follow‐up 2 and reduces obesity related comorbidities and mortality 2–4 . As a result, it is increasingly applied and is now considered the most effective treatment for obesity 5 …”

A systematic review and meta‐analyses of food preference modifications after bariatric surgery

et al. 2021

Summary This systematic review and meta‐analyses aimed to synthesize evidence of the link between bariatric surgery and changes in food preferences, considering the method of assessment. MEDLINE, Cochrane Library, Web of Science, Cinahl, PsychINFO, ProQuest, and Open grey were searched incorporating two blocks of terms (“Intervention” and “Food Preferences”). Interventional or observational studies involving patients (BMI ≥ 35 kg m−2) with sleeve gastrectomy (SG) or Roux‐en‐Y Gastric Bypass (RYGB) and a control group were included. Meta‐analyses were performed comparing the standardized daily mean percentage energy from proteins, carbohydrates, and lipids between preoperative and postoperative patients. Fifty‐seven studies concerning 2,271 patients with RYGB and 903 patients with SG met the inclusion criteria, of which 24 were eligible for meta‐analysis. Despite a total reduction in macronutrient intakes, the meta‐analyses revealed a postoperative increase in percentage energy from proteins at 12 months (0.24, 95% CI: 0.03, 0.46, {I2} = 73%) and a decrease in percentage energy from fat at 1 month (−0.47, 95% CI: 0.86, 0.09, {I2} = 72%), up to 24 months (−0.20, 95% CI: −0.31, 0.08, {I2} = 0%). In conclusion, the present systematic review and meta‐analyses showed changes of food preferences in terms of macronutrient, food selection and, overall food appreciation up to 5 years following bariatric surgery.

Fifteen Years After Sleeve Gastrectomy: Weight Loss, Remission of Associated Medical Problems, Quality of Life, and Conversions to Roux-en-Y Gastric Bypass—Long-Term Follow-Up in a Multicenter Study

et al. 2021

Purpose Since 2014, sleeve gastrectomy (SG) has been the most frequently performed bariatric-metabolic operation worldwide (2018: 386,096). There are only a few studies reporting a long-term follow-up (up to 11 years) available today. The aim of this study was to evaluate the long-term outcome of SG with a follow-up of at least 15 years regarding weight loss, remission of associated medical problems (AMP), conversions, and quality of life (QOL). Setting Multicenter cross-sectional study; university hospital. Methods This study includes all patients who had SG before 2005 at the participating bariatric centers. History of weight, AMP, conversions, and QOL were evaluated by interview at our bariatric center. Results Fifty-three patients met the inclusion criteria of a minimal follow-up of 15 years. Weight and body mass index at the time of the SG were 136.8kg and 48.7kg/m2. Twenty-six patients (49.1%) were converted to Roux-en-Y gastric bypass (RYGB) for weight regain and gastroesophageal reflux within the follow-up period. Total weight loss after 15 years was 31.5% in the non-converted group and 32.9% in the converted group. Remission rates of AMP and QOL were stable over the follow-up period. Conclusion Fifteen years after SG, a stable postoperative weight was observed at the cost of a high conversion rate. Patients converted to RYGB were able to achieve further weight loss and preserve good remission rates of AMP. SG in patients without the need of a conversion to another bariatric-metabolic procedure may be considered effective. Careful preoperative patient selection is mandatory when performing SG.
