Laparoscopic management of acute torsion of the omentum in adults.
BACKGROUND
Acute torsion of the greater omentum is a rare cause of acute abdomen in adults. We report our experience on the clinical presentation, diagnosis, treatment, and outcome of this condition.


METHODS
This is a retrospective review of 9 patients who had a clinicopathologic diagnosis of acute torsion of the greater omentum and were treated at the Department of Surgery, Pamela Youde Nethersole Eastern Hospital from January 1994 to March 2004. Eight patients were male and 1 was female with a median age of 43 years (range, 24 to 65). Median body mass index was 24 kg/m(2) (range, 22 to 24). All presented with acute abdominal pain with a median temperature of 36.8 degrees C (range, 36.5 to 37.2) and a median white cell count of 9.5 x 10(9)/L (range, 7.4 to 15.1 x 10(9)). Preoperative ultrasound was done in 5 patients.


RESULTS
All diagnoses were made during surgery. Resection of the infarcted omentum was performed for all patients (5 laparoscopic resections and 4 open resections). No postoperative complications occurred. The overall median time from admission to operation was 23 hours (range, 2 to 98). The overall median operating time and postoperative stay were 70 minutes (range, 38 to 105) and 3 days (range, 1 to 6), respectively. The median oral and parenteral analgesic requirement for postoperative pain control was less and the median hospital stay was shorter in patients who underwent laparoscopic resection.


CONCLUSIONS
Acute torsion of the greater omentum is an uncommon cause of acute abdomen in adults, and preoperative diagnosis is usually difficult. Laparoscopy seems a safe and minimally invasive technique for both diagnosis and treatment of this rare disease entity.
