Learning objectives -  To review the most common postoperative imaging findings following abdominal surgery.-  To review the imaging findings and radiological approach for the evaluation of the most common postoperative complications, including general, hepatobiliary, pancreatic, and gastrointestinal surgery.
Read more Background In the postoperative period, radiologic imaging is essential for identifying and differentiating common and expected postoperative imaging results from potential complications.  For radiologists, the early postoperative phase can be difficult since normal findings and problems frequently share traits. Numerous issues may arise throughout all surgical procedures, while others are particular to the specific operation conducted.Types of postoperative complications are variable and depend on: Type of surgical procedure Indication for surgery Severity of presentation Comorbidity conditions or concomitant disease entities Timing in relation to the operation Length...
Read more Findings and procedure details The predominant complications associated with abdominal procedures include internal hernias, adhesions, surgical site infections, abscesses, active bleeding, hematomas, anastomotic leaks, fluid collections, stenosis, and iatrogenic injuries. The most common disease-related complications are primarily linked to neoplastic or inflammatory recurrence. Following any abdominal surgery, certain complications may arise and present similarly on imaging. Surgical Site InfectionsAfter major abdominal surgery, approximately 5-10% of patients may develop wound complications. These include wound dehiscence, seromas, hematomas, surgical site infections and hernias. Depending on whether the...
Read more Conclusion Knowledge of the most common complications following abdominal surgery during the postoperative period is crucial for every radiologist to ensure timely diagnosis of potentially life-threatening situations and appropriate therapeutic planning.
