Efficacy and Safety of Laparoscopic Endoscopic Cooperative Surgery in Upper Gastrointestinal Lesions: A Systematic Review and Meta-Analysis.

Background And Aims: Laparoscopic and endoscopic cooperative surgery (LECS) combines advantages of endoscopy and laparoscopy in order to resect upper gastrointestinal lesions. Our aim was to evaluate the efficacy and safety of LECS in patients with EGJ (esophagogastric junction), gastric and duodenal lesions, as well as to compare LECS with pure endoscopic and pure laparoscopic procedures.

Methods: PubMed, Scopus, and ISI Web of Knowledge were searched.

[Laparoscopic cholecystectomy and open cholecystectomy in acute cholecystitis: critical analysis of 520 cases].

Introduction: Despite the skepticism with which it was initially seen, laparoscopic cholecystectomy is now the technique of choice for acute cholecystitis. It is, however, important to evaluate the results in comparison with classic cholecystectomy, since the latter is still used by some surgeons in certain situations.

Material And Methods: Our research corresponds to the analysis of 520 patients operated on for acute cholecystitis performed in the department of surgery at the SÉo JoÉo Hospital in Oporto - 412 (79.
