4-Ports Cholecystectomy (4PC): a 12mmHg pneumoperitoeum is created either by a 10mm umbelical Hasson's port or by a Verress needle followed by a 10 mm umbelical port insertion; further one 10mm and two 5mm ports are placed according to the preferred technique. A straight or angulated laparoscope may be used. Laparoscopic graspers, monopolar hook, bipolar forceps, scissors and 10mm clips-applier are used. A plastic bag system might be used for gall bladder extraction if necessary. In both 10 and 12mm accesses, fascia is sutured with resorbable sutures. Skin is secured by either metallic agraffes or interrupted sutures.
