An innovative laparoscopic and endoscopic technique in an animal model: combined gastric full-thickness tumor resection.

 The combination of endoscopy with laparoscopy for full-thickness gastric resection has received much attention. The advantage in using it is removak of the target lesion without resection of excessive normal tissue. The technique could prevent deformed scars, particularly at the cardia and in the prepyloric area.

ENDOSCOPIC CHANGES RELATED TO GASTROESOPHAGEAL REFLUX DISEASE: COMPARATIVE STUDY AMONG BARIATRIC SURGERY PATIENTS.

Background: Obesity is correlated with several comorbidities, including gastroesophageal reflux disease. Its main complications are detectable by endoscopy: erosive esophagitis and Barrett's esophagus.

Aim: To correlate erosive esophagitis and hiatal hernia with the degree of body mass index (BMI).

Do Archaea and bacteria co-infection have a role in the pathogenesis of chronic chagasic cardiopathy?

Unlabelled: Chronic cardiopathy (CC) in Chagas disease is a fibrotic myocarditis with C5b-9 complement deposition. Mycoplasma and Chlamydia may interfere with the complement response. Proteolytic enzymes and archaeal genes that have been described in Trypanosoma cruzi may increase its virulence.
