Anatomical malformations and vascular anomalies are predisposing factors. SOT is a more common

condition than POT, due to pre-existing abdominal pathology: cysts, tumours, abdominal inflammatory foci, postsurgical wounds and hernial sacs. The symptoms and the laboratory findings of POT are not specific and mimic other pathological abdominal conditions, for these reasons they make loose time to make Silmitasertib price diagnosis and provoke increasing degree and duration of OT. The differential diagnosis between POT and SOT is difficult and has seldom been made during the surgical operation. Helpful are US and/or CT scan. MRI can be effective when OT is accompanied by infarction or abscess. Explorative laparotomy represents click here a diagnostic and definitive therapeutic procedure. Nowadays laparoscopy is the first choice procedure for diagnosis and treatment of acute abdominal torsion. In cases of POT with extensive mass of omentum, diagnostic laparoscopy followed by laparotomy could permit the omental excision with small abdominal incison. Consent The patient knew about this case report and he signed a consent statement. A copy of the written consent was in the patient medical record.
