5-Year Collis-Nissen Gastroplasty Outcomes for Type III-IV Hiatal Hernia with Short Esophagus: A Prospective Observational Study.

Background: To assess the 5-year outcomes of patients undergoing Collis-Nissen gastroplasty for type III-IV hiatal hernia with short esophagus.

Study Design: From a prospective observational cohort of patients who underwent antireflux surgery for type III-IV hiatal hernia between 2009 and 2020, those with short esophagus (abdominal length <2.5 cm) in whom a Collis-Nissen procedure was performed and reached at least 5 years of follow-up were identified.

Indication, performance and outcomes of adrenal vein sampling in patients with primary hyperaldosteronism.

Primary hyperaldosteronism (PAH) is an important cause of secondary hypertension (HTN). The study of the same requires a high clinical suspicion in addition to a hormonal study that confirms hormonal hypersecretion. It is important to start the appropriate treatment once the diagnosis is confirmed, and for this is necessary to demonstrate whether the hormonal hypersecretion is unilateral (patients who could be candidates for surgical treatment) or bilateral (patients who are candidates for pharmacological treatment only).

Minimally invasive surgery in the era of step-up approach for treatment of severe acute pancreatitis.

Objectives: To assess the minimally invasive surgery into the step-up approach procedures as a standard treatment for severe acute pancreatitis and comparing its results with those obtained by classical management.

Methods: Retrospective cohort study comparative with two groups treated over two consecutive, equal periods of time were defined: group A, classic management with open necrosectomy from January 2006 to June 2010; and group B, management with the step-up approach with minimally invasive surgery from July 2010 to December 2014.

Results: In group A, 83 patients with severe acute pancreatitis were treated, of whom 19 underwent at least one laparotomy, and in 5 any minimally invasive surgery.
