Efficacy of novel reduced volume oral contrasted computed tomography protocol for detection of early
leaks after sleeve gastrectomy for obesity

O
besity is a modern world epidemic and 50% of European population between 35-65 years is either overweight or obese. Sleeve
gastrectomy gained popularity as a practical obesity surgery technique. One of the most drastic complications after sleeve
gastrectomy is staple line leak, occurring between 1 to 3% of patients. Prompt management of staple line leak is essential in avoiding
prolonged hospital stay and mortality. Recent studies showed that, radiologic contrast agent upper gastrointestinal examination
has low sensitivity for detection of leaks. In case of clinical suspicion of a leak, computed tomography scan with oral contrast agent
is recommended. But there is not enough prospective data on efficacy and methodology (timing, volume of oral contrast, etc.,) of
routine computed tomography after sleeve gastrectomy. Our objective of this study was to prospectively evaluate the efficacy of upper
abdomen computed tomography on postoperative day three after sleeve gastrectomy using only 50 cc oral contrast agent in 500 cc of
drinking water. Patients were instructed to drink the last 50 cc of water just before lying on gantry. For this purpose, 168 patients who
underwent laparoscopic sleeve gastrectomy were included in the study. Patients were started with oral feeds, if computed tomography
was negative for a leak and discharged. They were followed as outpatient on first, third, sixth and 12th months. None of the patients
with a tomography negative for a leak had a clinically manifest leak on follow up (Sensitivity 100%). Our study showed that using
minimal amount of only oral contrast agent, accurate timing and only with upper abdomen sections leaks can be detected with very
high accuracy.
