Quantitative and Topographic Analysis by Immunohistochemical Expression of Ghrelin Gastric Cells in Patients with Morbid Obesity.

Purpose: The cellular distribution of ghrelin positive cells is not well defined. The aim of the study is to quantify and determine the distribution of ghrelin cells in gastric mucosa in patients with morbid obesity and relate this finding to gender, comorbidities, gastritis, and plasmatic levels of acyl and desacylghrelin before and after laparoscopic sleeve gastrectomy.

Patient And Methods: We performed a study on 61 patients with BMI≥50 kg/m operated by laparoscopic sleeve gastrectomy.

Extralobar pulmonary sequestration with an unusual venous drainage to the portal vein: preoperative diagnosis and excision by video-assisted thoracoscopy.

Pulmonary sequestration is an uncommon congenital malformation of the lung that can be classified as intralobar or extralobar (ELS). Approximately 90% of ELS occur in the left hemithorax. Approximately 10% of ELS may present below the diaphragm.
