EUS-Guided Intragastric Injection of Botulinum Toxin A in the Preoperative Treatment of Super-Obese Patients: a Randomized Clinical Trial.

Background: Obesity is a disease that is highly prevalent in Brazil, and the associated comorbidities represent a major global public health challenge. Botulinum toxin type A (BTX-A) is a potent neurotoxin and inhibitor of gastric smooth muscle activity. In theory, BTX-A administration should promote early satiety and weight loss because it delays gastric emptying by inhibiting acetylcholine-mediated peristalsis, which is primarily responsible for gastric motility.

Improvement of Body Composition and Quality of Life Following Intragastric Balloon.

Background: The aim is to evaluate the effects of IGB in overweight or class I obese patients, by analyzing body composition and quality of life (QOL).

Methods: Prospective study including patients with BMI 27-34.9 kg/mbody composition analysis (BCA) was performed before IGB implantation and its removal, after 6 months of treatment.

A new technique for performing endoscopic pyloromyotomy by gastric submucosal tunnel dissection.

Aim: To investigate the feasibility of a new endoscopic pyloromyotomy technique.

Materials And Methods: Endoscopic pyloromyotomy through a gastric submucosal tunnel was performed in 6 pigs. At the greater curvature, 2 cm proximal to the pylorus, we incised the mucosa and dissected the submucosal tunnel up to the pyloric ring.
