Background: Guidelines recommending antibiotic prophylaxis at emergency cholecystectomy for cholecystitis were based on low-quality evidence. The aim of this trial was to demonstrate that omitting antibiotics is not inferior to their prophylactic use.

Methods: This multicentre, randomized, open-label, non-inferiority clinical trial randomly assigned adults with mild-to-moderate acute calculous cholecystitis (immediate cholecystectomy indicated) to 2 g cefazolin administered before incision or no antibiotic prophylaxis.

Objective: To assess whether laparoscopic cholecystectomy is superior to percutaneous catheter drainage in high risk patients with acute calculous cholecystitis.

Design: Multicentre, randomised controlled, superiority trial.

Setting: 11 hospitals in the Netherlands, February 2011 to January 2016.

Cleft lip with or without cleft palate (CP) is one of the most common congenital malformations. Ultrasonographers involved in the routine 20-wk ultrasound screening could encounter these malformations. The face and palate develop in a very characteristic way.

Background: The additional value of perioperative antibiotic prophylaxis in preventing infectious complications after emergency cholecystectomy for acute cholecystitis is a much-debated subject in the surgical community. Evidence-based guidelines are lacking, and consequently the use of antibiotic prophylaxis varies greatly among surgeons and hospitals. Recently, high-level evidence became available demonstrating that postoperative antibiotic prophylaxis in patients with acute cholecystitis does not reduce the risk of infectious complications.

Introduction: According to the Tokyo Guidelines, severity of acute cholecystitis is divided into three grades based on the degree of inflammation and the presence of organ dysfunction. These guidelines recommend grade I (mild) acute cholecystitis to be treated with early laparoscopic cholecystectomy and grade II (moderate) acute cholecystitis with delayed cholecystectomy. Yet, several studies have shown that, for acute cholecystitis in general, early cholecystectomy is superior to delayed cholecystectomy in terms of complication rate, duration of hospital stay and costs.

Background: In the era of advanced surgical techniques and improved perioperative care, the willingness to perform emergency operations in elderly patients continues to increase. This systematic review aimed at assessing the clinical outcomes of early cholecystectomy in elderly patients with acute cholecystitis.

Methods: Medline, Embase, and Cochrane Library databases were systematically searched for studies reporting on early cholecystectomy for acute cholecystitis in patients aged ≥70 years.

Background: In medical practice, the tendency to remove an inflamed gallbladder is deeply rooted. Cholecystectomy, however, is associated with relatively high complication rates, and therefore the decision whether or not to perform surgery should be well considered. For some patients, the surgical risk-benefit profile may favour conservative treatment.
