After reading the interesting article “Predictive value of upper gastrointestinal studies versus clinical signs for gastrointestinal leaks after laparoscopic gastric bypass” by Madan [1] et al., we want to contribute our opinion about the use of routine imaging tests (RIT) after laparoscopic Roux-en-Y gastric bypass (LRYGB). The efficiency of upper gastrointestinal (UGI) studies relies mainly on radiologist experience; besides, it is well known that computed tomography (CT) scanning has a better sensitivity and specificity [2] than UGI studies for detection of leaks. Therefore we consider that in the case of clinical suspicions of any complications after LRYGB, a CT scan with isotonic oral contrast must be requested and UGI studies should be limited only to patients with a weight over the CT scanner limit (most frequently 180 kg). In the last few years, surgeons have acquired great experience in bariatric surgery, which has been translated into a significant decrease in leak rates [3], such that the most experienced bariatric surgeons show leak rates under 1%. For this reason, we do not support the routine use of any RIT after LRYGB, but to perform them when patient’s clinical signs and symptoms require us to do so.
