Gastric antral vascular ectasia (GAVE) is an uncommon cause of chronic gastrointestinal bleeding or iron deficiency anemia. [1] [2] The condition is associated with dilated small blood vessels in the gastric antrum, which is a distal part of the stomach. [1] The dilated vessels result in intestinal bleeding. [3]
It may be performed laparoscopically, and the average recovery time is approximately two weeks. [8] The weight loss success rate after Roux-en-Y gastric bypass revision surgery is generally excellent. [9] There are some associated risks of vitamin deficiency and stomach ulcer formation requiring prevention with multivitamins and proton pump ...
Iron-deficiency anemia can occur as the stomach normally converts iron into its absorbable form. [2] Another side effect is the loss of ghrelin production, which has been shown to be compensated after a while. [3] Lastly, this procedure is post-operatively associated with decreased bone density and higher incidence of bone fractures. This may ...
Vitamin B 12 deficiency is quite common after gastric bypass surgery with reported rates of 30% in some clinical trials. [journal 13] Sublingual B 12 (cyanocobalamin) appears to be adequately absorbed. In cases where sublingual B 12 does not provide sufficient amounts, injections may be needed. Protein malnutrition is a real risk.
In one report 10% of 100 people investigated for iron deficiency anemia had a large hiatal hernia. [3] A 1967 review found that 20% of 1305 individuals having surgery for hiatal hernia were anemic. [4] Cameron in 1976 [5] compared 259 people with large hiatal hernias visible on chest x-ray with 259 controls without hernias. Present or past ...
The SADI-S is a single anastomosis bariatric surgery. It is different from the classic duodenal switch, the gastric bypass (RNY) or sleeve gastrectomy.It is a type of bariatric surgery carried out to lose weight and to mitigate various metabolic issues including type 2 diabetes, dislipidemia, metabolic syndrome, and polycystic ovary syndrome.
However, B 12 deficiency after gastric surgery does not usually become a clinical issue. This is probably because the body stores many years' worth of B 12 in the liver and gastric surgery patients are adequately supplemented with the vitamin. [44] [45]
In a recent propensity score-matched study, the difference in weight loss for LSG vs ESG was 9.7% at 1 year, 6.0% at 2 years, and 4.8% at 3 years in favor of LSG, though the authors described the ESG as non-inferior based on an a priori definition of non-inferiority as being within 10% total body weight loss of the surgical arm.
