Laparoscopic or robotic intraoperative management to minimize aerosol dispersion: Adaptations to the context of the COVID-19 pandemic.

The coronavirus infection, also known as SARS-COV2, has proven to be potentially fatal, representing a major global health problem. Its spread after its origin in the city of Wuhan, China has resulted in a pandemic with the collapse of the health system in several countries, some with enormous social impact and expressive number of deaths as seen in Italy and Spain.

Esophagectomy with gastroplasty in advanced megaesophagus: late results of omeprazole use.

Objective: To analyze the late results of advanced Chagasic megaesophagus treatment by esophagectomy associated with the use of proton pump inhibitor (omeprazole) as for the incidence of esophagitis and Barrett's esophagus in the remaining stump.

Methods: We studied patients with advanced megaesophagus undergoing esophagectomy and transmediastinal esophagogastroplasty. Patients were divided into three groups: A (20) with esophageal replacement by full stomach, without the use of omeprazole; B (20) with esophageal replacement by full stomach, with omeprazole 40 mg/day introduced after the first postoperative endoscopy and maintained for six years; and C (30) with esophageal replacement by gastric tube with use of omeprazole.

Analysis of transplant rejection in rabbits aponeurosis.

Objective: To study the feasibility of heterologous aponeurosis to close the abdominal wall of rabbits emphasizing the rejection process.

Methods: This project was approved by the Animals Care Committee of the Faculdade de Ciências Médicas da Santa Casa de São Paulo, and it was carried out at the Experimental Surgery and Technical Unit. Four red female rabbits exchanged abdominal wall aponeurosis with other four white male animals.

[Factors related to the presence of reflux in patients with typical symptoms of gastroesophageal reflux disease (GERD)].

Objective: To analyze clinical, abdominal ultrasound, upper digestive endoscopic, esophageal manometric and prolonged esophageal pH-monitoring findings in patients with typical symptoms of GERD.

Methods: The study included a total of 251 patients with typical GERD symptoms. Clinical data, Body Mass Index, abdominal ultrasound aspects and upper digestive endoscopic data are reported.
