Computerized tomography safe after laparoscopic gastric bypass.
2004 DEC 27 - (NewsRx.com & NewsRx.net) -- Computerized tomography is safe after laparoscopic Roux-en-Y gastric bypass for patients with suspected complications.
"Early detection of complications after laparoscopic Roux-en-Y gastric bypass (LRYGB) can be difficult because of the subtle clinical findings in obese patients. Consequently, routine postoperative upper gastrointestinal contrast studies (UGI) have been advocated for detection of leak from the gastrojejunostomy. The medical records of 368 consecutive patients undergoing LRYGB were analyzed to determine the efficacy of selective use of radiological studies after LRYGB," investigators in the United States report.
"Forty-one patients (11%) developed signs suggestive of complications. Of the 41 symptomatic patients, two were explored urgently, 39 (10%) had radiological studies, and 16 of them (41%) were diagnosed with postoperative complications," stated S. Lyass and colleagues at Cedars-Sinai Medical Center. "Overall morbidity of the series was 4.8%. Four patients (1.1%) developed a leak from the gastrojejunostomy and were correctly diagnosed by computerized tomography (CT). The sensitivity and specificity of CT in determining leak was 100%, with positive and negative predictive value of 100%. The mortality of the series was 0%."
"No radiologic studies were ...
