[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.

Laparoscopic cholecystectomy in acute cholecystitis in the elderly.

Background/aims: Benefits of using laparoscopic cholecystectomy (LC) in the elderly with acute cholecystitis (AC) is still questionable. Our aim is to carry out a comparative analysis of that intervention in two groups of patients: under 65 years old, and over or equal to 65 years old.

Methodology: This study corresponds to 249 LCs carried out during 4 years at the Emergency and Surgery Department of Hospital de S.

Durability of long-term outcome of laparoscopic Nissen - comparison of the results at 5 and 10 years after surgery .

Background/aims: It is not sufficiently clear whether the continued good outcomes obtained with laparoscopic Nissen operation after a short follow-up will continue after several years. The aim of our re-search was to make a comparative analysis of the quality of life and presence of symptoms 5 and 10 years after surgery.

Methodology: 123 cases (69 men and 74 women) average age of 49.
