Clinical presentation of primary torsion of the greater omentum is nonspecific, thus rarely allowing for a preoperative diagnosis. Three patients presented with acute but nonspecific abdominal symptoms. Because ultrasonographic and radiologic findings were unclear, all patients underwent diagnostic laparoscopy. In all cases, laparoscopy enabled us to achieve the diagnosis and to perform a resection of necrotic omentum. The mean duration of the procedure was 56 minutes (range: 42 to 76). The postoperative course was uneventful and the patients were discharged on postoperative day 1 (2) and 3. The value of diagnostic laparoscopy increases when the disease can be treated laparoscopically. The laparoscopic vision allowed us to explore the whole peritoneal cavity, so achieving the diagnosis, and to place the operative trocars at the most convenient sites. The laparoscopic resection of the greater omentum is an easy task even for inexperienced laparoscopic surgeons, allowing patients to benefit from the advantages of a mini-invasive approach.
