Abstract

Background: Intra-abdominal adhesion is one of the most important complications of abdominopelvic surgery. It increases morbidity and mortality for patients. Although laparoscopy is the gold standard of adhesion diagnosis, it can cause visceral damage during the operation. Therefore, surgeons prefer to use non-invasive methods for planning the operation. We designed this study to evaluate transabdominal ultrasonography (TAU) accuracy for diagnosing Intra-abdominal Adhesions Material & methods: This double-blinded cohort study was conducted on 47 patients with previous laparotomy who undergo another surgery. Spontaneous visceral slide (SVS) and induced visceral slide (IVS) were measured during TAU. Results: The mean age and BMI of 47 patients were 43.21±10.3 and 27.545±5.76. The majority of the patients were female (76%). Mean SVS and IVS in patients with intra-abdominal adhesion were 8.73±1.60 and 44.84±11.60. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of TAU in intra-abdominal diagnosis were 83.33%, 51.72%, 51.72%, 83.33%, 63.83%. Conclusions: Although TAU is an appropriate method for detecting the intra-abdominal adhesion, it isn't good enough for diagnosing free adhesion area. We recommended further researches with greater sample size and other non-invasive techniques. © 2018 The Authors
